Professor Vogt noticed the hat before she noticed the student.

  She was midway through writing the day's formation topology on the board when she noticed something wrong. Thirty years of teaching had given her eyes in the back of her head. A hat. A baseball cap, worn indoors, in her lecture hall, at Phillips Exeter Academy.

  She turned slowly.

  Third row. Aisle seat. A boy she did not recognize, wearing a dark navy cap pulled low over his eyes. Sitting there like he'd been enrolled all semester.

  Professor Vogt did not appreciate hats in her classroom. She especially did not appreciate hats on heads she did not recognize, in seats that should contain students whose faces she knew.

  Professor Vogt had something adjacent to photographic memory for her student roster. She could name every junior studying the Dao Art, and recite their grades since freshman year.

  This boy was not in her memory.

  She set her chalk down and walked to her desk. Pulled up the attendance roster on her tablet. Scrolled. Referenced the seating chart with the face, or what she could see of it under the hat brim. Nothing matched. She expanded the search to the full junior class. Scrolled again.

  Chen, Leo.

  She stared at the name. Then at the thumbnail photo beside it. Then at the boy in the third row.

  Leo Chen. The only student who had skipped the mandatory enrollment sessions three years running. The ones where you got expelled for missing them.

  She looked at the hat again. The gold crossed arrows on the front.

  Ranked insignia. The boy had an ELO.

  Professor Vogt was German by upbringing, practical by nature, and old enough to know when a situation contained more trouble than it was worth. She had opinions about hats indoors. She had stronger opinions about students who treated her class like an elective they could attend on a whim.

  But she also had a functional sense of self-preservation, and the gold crossed arrows on that cap meant the boy wearing it had killed a Nascent Soul.

  She would not poke this bear.

  Professor Vogt put on her brightest smile. The one she reserved for parent-teacher conferences and department funding reviews.

  "Mr. Chen." She clasped her hands in front of her. "What a pleasant surprise. I don't believe I've had the pleasure of seeing you in class this year."

  "I've been busy."

  "I can imagine. You've been busy for approximately three years, by my records." She tilted her head. "So what brings you to my classroom today?"

  A few students turned to look at him. Leo shifted in his seat.

  "I wanted to learn about the Three Talents formation system."

  Professor Vogt's eyebrows rose. Her smile settled into something more genuine. More interested.

  "Well. That explains the visit." She walked back to the board and picked up her chalk. "The Three Talents system is not covered in the high school curriculum. Most students won't encounter it until their second or third year in university, and even then only in specialized tracks."

  She wrote HEAVEN - EARTH - MAN on the board.

  "The Heaven-Earth-Man formation system has fallen out of favor in modern formation work. The current meta, as your generation likes to say, focuses on engraving higher tier formations onto lower tier spiritual materials. This is what we call downgrading." She drew a quick diagram.

  "For example, collegiate-grade flying swords use Tier Four formations placed on Tier Two material substrates. The formation does the heavy lifting. The materials just need to hold the formations together."

  She tapped the Three Talents on the board.

  "The Three Talents are exceptionally difficult to downgrade. The concepts are too abstract. You would think that the hardest should be the Two Polarities, and those classically are the hardest to work with. But the physical sciences have made enormous progress describing polarity interactions."

  She underlined HEAVEN - EARTH - MAN.

  "The Three Talents don't have that luxury. How do you mathematically define Heaven? How do you quantify Man? These concepts resist the kind of precise specification that downgrading requires."

  She set down the chalk and turned to Leo.

  "Now. You came here with questions. There are no wrong questions in my classroom. What would you like to know?"

  Leo was quiet for a moment. The classroom waited. Thirty-two students, most of whom had been attending Professor Vogt's formations lectures for the last three years, watched the boy in the hat think.

  "What is a formation?"

  The room went quiet. They had just heard someone ask a question so terrifyingly absurd.

  A girl in the front row turned around fully in her seat to stare. Two boys in the back exchanged a glance that communicated an entire conversation.

  Leo coughed. He raised a hand, half-defensive.

  "I should clarify. I'm really only good at one thing, and that's fighting with my flying sword."

  Professor Vogt studied him. The bright smile was gone.

  "What is your divine sense rating, Mr. Chen?"

  "Seven thousand fifty-eight."

  The room held still for half a second. Then it exploded.

  "Seven THOUSAND?"

  "What the hell!"

  "Wait, is that Leo Chen? The one who won us the championship last year?"

  "He's in our class? He's been in our class?"

  Professor Vogt let the eruption run for five seconds, then raised one hand. The room died.

  "Mr. Chen." Her voice was careful. Measured. "With a divine sense of seven thousand, you could have pursued dao arts at a very high level. Formation theory, alchemy, divination. Safer disciplines. More academically and financially rewarding. Why didn't you?"

  Leo leaned back in his chair.

  "Everyone told me that transport missions in the Catacombs were very safe and basically free merits."

  "I don't really know what happened after that. One thing led to another and I found out what an army of three hundred Nascent Souls looks like. The hard way."

  A murmur rolled through the classroom. Heads nodded. Boston Command's recruitment trick had apparently worked on many of them. Sign up for convoy escort duty, they said. Easy merits, they said. See the Catacombs from the safety of a Tier Four transport hull, they said.

  Nobody mentioned the part where you discovered what the inside of a Domain looked like on a very personal level.

  Professor Vogt sighed. She had seen too many students vanish from her roster permanently.

  "Very well. Let's start from the beginning."

  She turned to the board and began writing.

  "A formation is a structured arrangement of spiritual energy, anchored by physical or conceptual nodes, designed to produce a repeatable effect on the world. Think of it as a blueprint that tells spiritual qi what to do and where to do it."

  Her chalk moved in clean, confident strokes.

  "At the most basic level, a formation has three components. The substrate, which is the physical medium that holds the formation in place. The pathways, channels through which spiritual qi flows according to the formation's design. And the core logic, the arrangement of nodes that determines what the formation actually does."

  This tale has been unlawfully lifted without the author's consent. Report any appearances on Amazon.

  She drew a simple circle with three points inside it.

  "A Tier One illumination formation, for example, uses a jade chip as substrate, two carved channels as pathways, and a single brightness node as core logic. Qi enters, follows the channels, hits the node, and the chip glows. Simple. Predictable. The foundation of everything we do."

  She paused. Turned to make sure Leo was following. He was. His pen was moving.

  "Now." Her voice quickened. "When we extend this to higher-order formations, we encounter the problem of recursive node dependency, where the output of one formation node serves as the input for another, creating feedback loops that require simultaneous solving across all nodes. This is why Tier Three and above formations cannot be designed sequentially. They must be conceived holistically..."

  She looked at Leo.

  His eyes had glazed over. The pen had stopped moving.

  "...which we will set aside for now." Professor Vogt put down her chalk. "Mr. Chen. Tell me specifically what you're trying to do."

  Leo straightened.

  "I'm cultivating a dao heart technique called the Heart of Flesh. A friend of mine who studies formations suggested I think about it through the lens of the Three Talents."

  Professor Vogt leaned against the edge of her desk.

  "I'm not familiar with the Heart of Flesh specifically. But any dao heart technique worth its name will touch upon the Man element of the Three Talents." She paused, choosing her words. "Let me tell you something useful, then."

  She walked to the board and drew the Three Talents triangle again. Heaven at the top. Earth at the bottom left. Man at the bottom right.

  "The man formation is very important because it handles various forms of control. Most notably, divine sense control, which is probably the most important aspect of treasures such as your flying sword."

  She drew a small sword icon.

  "But since the Three Talents resists downgrading, modern formation engineers had to find a workaround. Their solution was lifebonding." She drew a line from MAN to a small sword icon.

  "By lifebonding a weapon, you replace the man formation with yourself. Your divine sense becomes the control mechanism. This is why lifebonding has become so standardized for weapons. It solves the Man problem by removing it from the formation entirely and putting a living cultivator in its place."

  Leo asked. "So the Man formation is about divine sense?"

  "Divine sense is one superficial manifestation, yes. But only one." Professor Vogt held up her hand and counted on her fingers. "Picking up a weapon. That's Man. Speaking with your voice. Man. Thinking a thought. Choosing to act. All Man." She lowered her hand.

  "Divine sense is how you reach out and perceive. But Man encompasses everything about how a living being interfaces with reality. A person's 'Will', so to speak."

  She let that settle, then turned back to the board and wrote beneath the triangle:

  Heaven gives shape to Earth. Earth gives foundation to Man. Man gives meaning to Heaven.

  "This is the classical description taught to us from our ancestors. Clean and Elegant." She set down the chalk and folded her arms. "But let me ask you a question, Mr. Chen. Do you have free will?"

  Leo opened his mouth. Closed it.

  "Think about it. If Earth gives foundation to Man, and Man is a product of his environment, his upbringing, his spiritual roots, his family lineage, then in what sense is Man independent? The Legacy Sects claimed you could calculate any person's maximum possible cultivation realm from their spiritual roots and family background alone. Destiny, predetermined by Earth." She pointed at the triangle.

  "And if Man has no free will, if Man is merely the sum of Earth's influences, then what meaning can Man give to Heaven? The entire formation loses coherence if the Man node is just a passive reflection of the Earth node."

  The classroom was quiet.

  Leo stared at the board. "How can anyone even design formations with questions like that? You'd go insane."

  Professor Vogt smiled. The first real smile she'd shown all class.

  "Mr. Chen, the history of formation theory is the history of locking enough talented people in rooms with formation brushes and seeing what they produce. Given sufficient time and sufficient monkeys, you can derive almost anything."

  A laugh rippled through the classroom.

  Leo looked at the triangle. Heaven. Earth. Man.

  Something clicked.

  He had two Heavens. Two Earths. The Azure Profound Continent and Earth. Two completely different realities, two systems of karma. And before that, if he counted his life before transmigration, before the Catacombs opened, that was yet another configuration. Another Earth beneath another Heaven.

  His destiny should have been calculable. His spiritual roots and his family said Qi Refining at best. That was what the ancient formula would have predicted.

  But he'd broken the formula. He'd transcended it. Because he had access to a multiple Earths beneath multiple Heavens, and the sum of those inputs produced an outcome that neither system could have predicted alone.

  "Professor."

  "Yes?"

  "Earth and the Catacombs. That's two Heavens and two Earths. One Man." He tapped his pen against the notebook. "Everyone in this school has access to both. Does the Three Talents framework account for that?"

  Professor Vogt's expression sharpened.

  "That," she said, "is the question that keeps several very well-funded research departments awake at night." She walked back to the board and drew a second triangle overlapping the first.

  "The classical Three Talents assumes one Heaven, one Earth, one Man. A single closed system. When the Catacombs opened and humanity gained access to a second realm, the model broke."

  She drew connecting lines between the two triangles.

  "The dominant assumption is that the situation is inherently unstable. Two Heavens, two Earths, one Man. The system resolves through destruction. War until one Heaven and one Earth are eliminated, and the classical balance is restored."

  "War until the Catacombs or Earth is destroyed," Leo said.

  "That is the prevailing theory, yes." Professor Vogt set down her chalk. She stared at the overlapping triangles for a long moment. "But I think differently."

  She turned to the class.

  "The classical Three Talents formation isolates Man. Man is a single node, a single point. But are humans not social creatures? Where is everyone else in this model?"

  She gestured at the room. "Thirty-three students in this classroom. Billions of people on Earth. Tens of billions more in the Catacombs. The Man node isn't singular. We do not exist alone."

  She erased the bottom-right point of the triangle and redrew it as a cluster of dots.

  "Maybe Earth isn't the ground beneath our feet. Maybe Earth is the accumulated history of what Man has already done. The product of past choices. Past actions. The foundation that previous generations of Man built for the current one." She relabeled the bottom-left point: PAST.

  "And maybe Heaven isn't the sky above. Maybe Heaven is the choices that Man will make. The future, unwritten, undefined, but giving shape to everything that follows." She relabeled the top point: FUTURE.

  She wrote MAN in the center. Drew a circle around it. And relabeled it: PRESENT.

  "Past. Present. Future. Earth is what was. Heaven is what will be. Man is the living moment between them." She set down the chalk. "And if that's true, then two Earths and two Heavens doesn't mean war. It means a richer past and a wider future."

  She brushed chalk dust from her fingers.

  "The ancient classification may simply be wrong."

  Leo stared at the board. Past. Present. Future. Man as the living moment, the point where accumulated history met unmade choices. He thought about the crowd at the Florida game. The chanting. His heartbeat syncing with fifty thousand people. Man to Earth. Present resonating with past. And somewhere ahead, the choices that would give shape to everything after.

  He closed his notebook.

  "Thank you, Professor."

  Professor Vogt nodded. The fake smile was long gone, replaced by the look of a teacher who'd just given an unplanned lecture and found it more interesting than the one she'd prepared.

  "You're welcome, Mr. Chen. Do try to attend more than once every three years. I hope to see you again"

  ---

  Leo sat across from Tom in the dining hall, picking at a plate of food slowly. The usual lunchtime roar surrounded them.

  He'd been scanning the room for twenty minutes.

  "You're doing it again," Tom said.

  "Doing what?"

  "Looking around like you're expecting something."

  "I'm not expecting anything."

  "I know when you're disappointed Leo."

  Leo stabbed a piece of chicken. "I just thought, you know. After the Florida game. The highlights. Maybe someone would..." He trailed off.

  Tom waited.

  "No girl has given me her number, Tom."

  Tom set down his fork. He had the expression of a man choosing his next words very carefully.

  "Leo."

  "What."

  "Kim Yuna has warned off the entire school."

  Leo stared at him.

  Tom picked his fork back up. "Nobody wants to make enemies with her."

  "We're not even together!"

  "And yet."

  Leo opened his mouth to protest further, but a shadow fell across the table.

  Kim Yuna sat down beside him. She placed her tray on the table with a deliberate clank, announcing her presence. Her uniform was immaculate. Her expression could have frozen a spirit vein.

  "Leo."

  "Yuna."

  "I leave you alone for a few weeks and you already have wandering eyes."

  Leo decided to change the subject as fast as humanly possible.

  "How have the Catacombs been going in Korea?"

  Yuna's chopsticks paused over her tray.

  "Only America can throw forbidden formations at all their problems." She said it flatly. "The rest of the world has to pay with their blood."

  Leo blinked. "What do you mean?"

  "America is the country with the most T5 spirit veins and can just throw T5 formations on everything, even their transports." She set her chopsticks down. "Why else do you think your parents tried so hard to immigrate here?"

  Leo frowned. "My parents immigrated because they only wanted one child. China's three-child policy would have required them to have two more."

  Yuna shook her head slowly.

  "The rest of the world didn't have the Scorpions, Leo. They paid for their Tier Three spirit veins with bodies." She picked her chopsticks back up.

  The dining hall noise continued around them. Leo's chicken sat untouched on his plate.

  "Your parents didn't leave China because of a child policy. They left because China's Catacombs campaign was a meat grinder, and they didn't want themselves, or their son into it."

  Leo stared at his tray. The world rearranged itself slightly.

  Yuna watched him for a moment, then her expression softened.

  "It's fine. I mean, America killed two thousand Nascent Souls across twenty-seven entrances. In hours. That's insane." She resumed eating. "The whole Catacombs offensive slowed down after that. Korea, Japan, Europe. Everyone got breathing room because the cults freaked out."

  Leo nodded slowly. He was still processing.

  A light pink blur appeared at the edge of his vision.

  Vivian slid into the seat across from Yuna, setting her bag on the table with a casual thump. It was a Hermès Divine Beast Birkin. Light pink, T5 leather. The hardware was rose gold. It was an extraordinary bag.

  Yuna's eyes locked onto it.

  "That's tacky," Yuna said. "Carrying around a designer bag and flaunting it in a school cafeteria."

  Vivian shrugged. She opened the bag, pulled out a tablet, and set it on the table. Then she looked at Yuna with a small, precise smile.

  "It's a gift from Leo. He picked it out for me."

  The temperature at the table dropped.

  Yuna turned to Leo. The fraction of softness that had appeared evaporated.

  "You bought her a bag."

  "I..."

  "You bought her an Hermès divine beast bag."

  "She drove the transport..."

  "I was on your transport too." Yuna glared.

  Leo was silent.

  "Valentine's Day," Yuna said. The words landed like a gavel. "I expect something. Don't disappoint me."

  She picked up her tray, stood, and walked away.

  Leo watched her go. Then he turned to Tom.

  "What was that about?"

  Tom glanced at Vivian, the sly smile still faintly visible at the corners of her mouth. He looked back at Leo. He considered his options.

  "Nobody understands women, Leo."

  Leo laughed.
