*(At 4 PM)*

  After following the Chief for the whole day, Kaida asked, “Chief, I carefully watched you perform your tasks. I get some practical experienow?”

  “Kids these days are so impatient,” the Chief replied. “Normally, you'd train for at least a month befetting near any patients. But since you're Mitsuru-sama’s student, I’ll cut that time down to a week.”

  The Chief then added, “My shift is over, so you head back o read some books,” before leaving.

  ‘Since my brother promised to teach me Genjutsu after this, I’ll let my shadow es hahe reading,’ Kaida thought, using the Wind Instantaneous Movement Jutsu to quickly head home.

  ...

  Shisui, havied, was training in the gardee being ae jonin at only 12, he was still far from his prime. This made him a prodigy both within the Uchiha d in Konoha.

  Kaida ehe house, saw Shisui, and walked toward him. With his Sharingan active, Shisui noticed Kaida as soon as he entered.

  “How was your day?” Shisui asked.

  “B. I have to shadow the Chief for a whole week without doing anything,” Kaida replied.

  “Observation is important for learning, Kaida. Take it seriously,” Shisui advised.

  “Okay, brother. Now we start enjutsu training?”

  “Sure, let’s head to the training area,” Shisui said, using the Body Flicker Jutsu to disappear.

  ‘Even with my Sharingan, I ’t follow his movement. He’s so fast,’ Kaida thought as he activated his own Sharingan and used the Wind Instantaneous Movement Jutsu to follow.

  When Kaida arrived, Shisui was casually standing near a tree. Kaida disrupted his chakra flow to check if he was under any illusion. Shisui vanished and reappeared behind him.

  “Good, at least you remember the basiow, try to divide your chakra between Yin and Yang as much as possible,” Shisui instructed.

  Activating his Sharingan, Kaida began dividing his chakra, and after five minutes, he projected a ratio of 91:9, with 91% Yin chakra.

  “That’s good enough. Now stop,” Shisui said. “We’re moving to the phase, which is both easy and tricky.”

  Kaida nodded aivated his Sharingan.

  “You just et the eyes of your oppo and send your chakra to their brain, specifically to the cerebral nervous system where the spine ects to the brain. Once you’ve established a chakra pathway, think of what you want them to see. The closer it is to reality, the easier it will be to fool them,” Shisui expined.

  “What do you mean by ‘closer to reality’?” Kaida asked.

  “It’s simple. Like earlier, I made it seem like I was standing here. Since you expected me to be here, your brain didn’t o be forced to accept something unusual. With enough trol and chakra, you even do something like this.”

  Shisui snapped his fingers, and the day turo night. Crows surrouhem, and Shisui grew bck wings from his back. Kaida’s immediate thought was, *‘So cool.’* He tried to disrupt his chakra but was shocked when the illusion didn’t break.

  Shisui chuckled at Kaida’s expression before stopping the Genjutsu.

  “How did you do that, brother? I couldn’t break the illusion even after knowing it was Genjutsu,” Kaida asked in amazement.

  “I made it seem like you dispersed your chakra when, iy, you didn’t,” Shisui expined, smiling.

  “Will I be able to do that someday?” Kaida asked.

  “You will, but only when your Yin chakra is at least 96% pure. For now, let’s focus on the basics,” Shisui replied.

  “Who am I going to practi?” Kaida asked.

  “Use your shadow es,” Shisui said.

  “Will Genjutsu even work on shadow es? They don’t have cerebral nervous systems, right?” Kaida questioned.

  “Yes, they don’t have a true nervous system, but they have something simir. Otherwise, how could they learn and help you train? They need some form of ‘brain,’” Shisui expined.

  “Oh, I see,” Kaida said, thinking, *‘If shadow es could resist Uchiha Genjutsu, they’d be the perfect ter, and the Uchiha’s power wouldn’t be so feared.’*

  “Now, start your training,” Shisui urged.

  Kaida created a shadow e and tried projeg his Yin chakra to its eyes, which was easier with his Sharingan active. He ected his chakra to the e’s “brain” and made it see a rabbit nearby.

  “Did you see a rabbit?” Kaida asked.

  “No, it wasn’t a rabbit. It was something terrifying. Let me show you,” the e said before dispersing.

  Kaida received the memory and realized he’d actally made the e see a flesh monster instead of a rabbit.

  “Were you hoping to get it right on your first try? Keep practig. Onaster this, I’ll teach you a jutsu that will improve your uanding of Genjutsu,” Shisui said, using the Body Flicker Jutsu to rest in a tree.

  Kaida created another e and tinued practig. After two hours, Shisui called out, “I’m heading back. e find me when you’ve either succeeded or run into trouble.”

  Kaida nodded and tinued practig. trolling chakra outside his body was difficult due to the imbaween Yin and Yang, but he persisted.
