The skies is dark since then. Devastation is everywhere, dragons that ready to devour the skyscrapers continuing to appear. Followed by land monsters who continue to appear from fragments of meteors that fall to the earth. Nowadays world are so inhabitable.

  "Brother, are you really going to go in there? The portal to the residence of those who are incredibly powerful?" Said Arthur's sister, Leia Thorne.

  "Of course, this is the only hope so that our world can return to normal right? A world without monsters that continue to appear, don't you want it?" Said Arthur.

  "But without you here, no one will be able to defeat those monsters! Your Mana control and your Mana capacity are the keys so we could survive!" After Leia said that, a burst of dragon breath erupted in the sky followed by meteors that continued to destroy the earth's surface.

  "I believe in you, Leia. You will continue my fight here, and I will continue to seek the truth and strength to stop these monsters that keep coming." He said while touching her cheek and wiping his sister's tears.

  WUNGG

  Their bodies were both covered in Mana, which meant Arthur was teaching his sister the techniques he learned about mana. Arthur removed his hand from Leia's cheek, and moved towards the portal.

  "I have taught you everything I apply when I use my mana, I hope you can understand it, I'm going now."

  "See you..." Leia said who still couldn't hold back her tears.

  "Hopefully we can meet again," Arthur said, who then entered the portal.

  ?? ?? ??

  "Huh?" Arthur said when he just opened his eyes.

  Arthur then woke up from the fertile soil. Arthur looked around and found that this world was so beautiful and lush, which is also full of tall and shady trees. Arthur decided to walk to see the forest around, to find out what was in this world.

  "Is there a place as beautiful as this on earth?" This place is so beautiful, like a forest in heaven, or is this really a heaven?

  As Arthur continued his journey through the forest, he found a skeleton. The skeleton was similar to a human skeleton but the skeleton had two horns and its body was twice as large as an ordinary human. Then Arthur approached the skeleton closer so he could observe it more clearly.

  "Hmm, what is this skeleton?" He said while digging around in the skeleton.

  "Eh?" When Arthur was ascertain into the skeleton, he found something he could hold and lift.

  SHUT

  He took the object from between the creature's skeleton and found something. It was a sword. The sword was quite long, not too heavy or even quite light for a sword this long. The blade of the sword was black with some characters that Arthur himself didn't know what they meant.

  "Hmm, I'll try a little, is that okay?" Arthur said while observing the sword carefully.

  WUNG SWING SUT

  He tried to slash and stab with the sword, it felt so light that he could swing it freely.

  "This is the greatest sword I've ever tried! Brother, you must..." When he was about to show it to his brother, he suddenly remembered that he came here alone.

  "Gosh, I've only been gone for a few minutes and I already miss my brother this much. How is he now?" Then he faced up to see the sky filled with the chirping of birds. The sky was clear, but a little cloudy.

  GROARRR

  "Huh!? What's that?" Arthur immediately took a position, ready to fight.

  BOOM JDUM BRUK

  Several trees were fell from a distance, and the fallen trees were getting closer to where Arthur was. The creature continued to make the trees to fall as it moved. Until finally, the creature was standing right in front of Arthur.

  ROAAAGH

  A creature that at least 6 meters tall, with yellow shining thorns covering its entire back along with its yellow shining claws that made it look like a very dangerous threat.

  SRING

  The creature then grazed Arthur, but Arthur managed to avoid the attack which then gave him the opportunity to attack the creature. His sword was then covered by his Mana and his feet were covered like a kind of cloud, which symbolizes the form of Mana in this world. Then Arthur kicked the ground as as hard as he can so he could slide towards the creature's neck and then...

  "HIYAT!" He slashed the creature's neck with his sword that was covered by his mana which he then changed the form of the Mana into flames.

  SWING

  The creature's head was finally cut off.

  BUK JEDUM

  His head fell to the ground and his body fell to the ground too.

  "Not too hard huh? It felt like fighting a sachet-sized monsters, haha." When Arthur was about to put his sword on his back, suddenly something came from the bushes.

  HAP

  From the bushes, three human figures (or not?) appeared with stunned expressions, seeing how the creature had fallen to the ground with its head even cut off. The three of them were women, wearing black clothes and one of them was wearing a ring with a crescent moon symbol, she had short black hair. The rest of them had blonde hair, one wavy and the other's straight.

  "Hey! You, over there!" Said a woman with black hair.

  "Yes?" Arthur replied.

  "Y- You killed this monster? This one?" Her expression seemed like she couldn't accept what was happening right now.

  "Yes? Why?" Arthur asked.

  "Did you have a hard time fighting it? Eh, it must have been hard a hard fight, right? Hahaha!"

  A case of literary theft: this tale is not rightfully on Amazon; if you see it, report the violation.

  "I only slashed it once. Is this creature that strong?"

  "WHAT!? Y- Are you kidding me?" The woman's expression became even more displeased with what Arthur had just said.

  "Hey, why would I joking right now?"

  The three women's expressions were now so stunned that their mouths were gaping.

  "Where are you from? Are you one of the powerful existences of the Celestials?" The woman continued.

  "Celestial? What Celestial? I come from earth. The one who should be asking is me, what is this place actually?"

  "What!? Don't tell me you're from the Abyssal?" Now Arthur was really confused by what the woman said.

  "What else is the Abyssal? Oh my, what are you talking about?"

  "If humans can be this strong, then there's must be a great feud between individuals in Essence that causes the power of immense Mana to leak into the Abyssal." The woman said.

  "Come on, follow us, we'll take you to The Forgotten Castle. I'll explain in more detail as we walk." The woman said.

  "Hmm, yeah okay. I'll just follow." Arthur was forced to follow because he had no purpose here. If they did anything, he just needed to slash them off. Because from their expressions it was clear that they were nothing compared to Arthur's strength.

  "Okay, we'll go! But before that, let's get to know each other first. I'm Selene, let's introduce ourselves too." Said the woman with short black hair.

  "My name is Stella." Said the woman with wavy blonde hair.

  "My name is Chloe." Said the woman with straight blonde hair.

  "My name is Arthur. Nice to meet you."

  "Okay, since we already know each other, now let's go!" Selene said.

  ?? ?? ??

  Chloe, Stella, Selene, and Arthur walked through the lush forest. Green leaves danced in the gentle breeze, while warm sunlight penetrated through the gaps in the trees, creating a beautiful light painting on the ground. The bright blue sky became the perfect backdrop for their journey to The Forgotten Castle, making Arthur's heart blossom and no longer haunted by the feeling of anxiety from the three women.

  Stella glanced at Arthur, then she thought: He's kinda handsome, his messy brown hair also seems to suit his face, and also his beautiful blue eyes, it feels like... Eh, what am I thinking about? Stella's glance was then returned by Arthur by looking back at her gently.

  "Is there something up Stella? That you're smiling like that?" Arthur asked.

  "Ah! Er, um.. it's nothing, hehe." Stella replied with her blushing face.

  "You must be really confused with the various terms I mentioned earlier?" Selene interrupted, changing the topic that Arthur and Stella were talking about.

  Oh my, thank you very much Miss Selene! You saved me from this embarrassment. Stella thought.

  "Of course, it's my first time here and you've presented me with strange terms in succession, how could I possibly understand?" Arthur snorted in annoyance.

  "Hehehe, sorry. Do you want me to explain? Also so that we don't get bored so much on our journey to The Forgotten Castle." Selene said.

  "Hmm, yeah okay. Then please start from Abyssal, Essence, Celestial, and whatever it is. I really don't understand that."

  "Ohhh! That's easy! So, in this world it's called the Creation Tree. We represent the form of this world as a tree, there are trees on earth, right?" Selene asked.

  "Yes, there are. Then?"

  "Well, since the form is like a tree, then the parts of this world are also the same as a tree. There are roots, trunk, branches or twigs, leaves, flowers, and fruits. Each part has its own name, Abyssal as the roots, Ascent as the trunk, Celestial as the branches or twigs, Starlight as the leaves, Essence as the fruit, and the most mysterious part of all, which is even considered as a myth, Eternity as a flower." Selene explained.

  "Then, where are we now?" Arthur asked further.

  "We are in Ascent, the trunk of the Creation Tree."

  "Then you said I came from Abyssal, right? Can you explain it in more detail?"

  "Oh, it's simple. Abyssal is manifested as a root, right? Well, each end of the root branch has one universe. Well, if you think about it, there are so many root branches, right? Which means that the universe is not just one but there are many universes scattered, which are also commonly called the multiverse. So indirectly, Abyssal is a multiverse."

  "Then, what about the Creation Tree?"

  "The mortals from Abyssal should not be able to enter the Creation Tree, because the dimensions are already very far apart. In fact, the Creation Tree is a place for immortal existences to live. Maybe you think the shape of the three of us is like ordinary humans, but we are originally immortal existences, we are not humans. Just so you know, the only mortal being here is you, even the beast you fought earlier was an immortal existence."

  "But isn't it strange that a mortal being like a human like me killed that beast? Even though it was actually an immortal existence."

  "Well, that's what I wonder. Is it that much the Mana leaked into Abyssal?"

  "Wait, does that mean that all this time in all the other multiverses in Abyssal there's not a single one that has a mana system?"

  "Actually there is, but it's not Pure Mana like the one you used when fighting that monster. The mana in the Creation Tree and the mana in Abyssal are very different. If you use Abyssal mana, or what people here call 'Replicated Mana', you won't even be able to scratch the beast's skin a bit."

  "I see. Actually I'm still not used to this mana, I just got it 1 week before I entered the portal to the Creation Tree. At that time, the world was shocked by their bodies suddenly feeling a strange sensation, like their body became much more healthier. Exactly thirty minutes after they felt that strangely pleasant sensation, monsters and dragons suddenly appeared, the sky became gloomy and chaos was everywhere. For those who can control the power of mana well, they are the ones who will fight those monsters." Arthur explained, with his face turning gloomy.

  "And you are one of them, right? And indeed the only one who can defeat them in the true meaning of defeat. I mean, the one and only human that could kill them is only you, and the rest of them just make them faint for a while. Am I right?" Selene asked

  "You could say that. Eh, how did you know that?" she asked back

  "It's clear from your eyes that you are so worried."

  "Ah, is that so? Haha." Arthur said with a bitter laugh.

  ?? ?? ??

  It was getting dark and the four of them decided to take a break. Arthur was collecting firewood for the campfire and the rest were laying out the mats they had brought. While Arthur was looking for firewood, he thought: Whether it's morning or night, this forest is still beautiful, huh?

  This forest is so beautiful like heaven. Fireflies and glowing plants create a stunning view, a wonder that is hard to find in places on earth.

  After exploring the forest for about thirty minutes, Arthur finally found at least ten firewoods. Because there was quite a lot of firewood, he carried the firewood by putting it on both of his shoulders while holding it so that it wouldn't fall. Arthur decided to return to his resting place.

  When he walked towards the place, he found something strange. Some of the bushes were swaying as if there were people in them, and the swaying of the bushes also followed wherever Arthur walked which made him suspicious.

  Should I change course? But what if it's not a person? Ah why am I bothering? better to continue. Arthur thought.

  After Arthur walked for a few minutes, he finally arrived at their resting place.

  "Finally you're here! What took you so long? You spent thirty minutes just looking some firewood!" Selene said.

  It seems like she's the most active out of the three of them, huh? Haha. Arthur thought while smiling slightly.

  "Hey, look at this on my shoulder, I'm looking for firewood as big as an elephant so we don't have to go back and forth looking for firewood again." Arthur replied, then dropped the firewood where they were going to light the campfire.

  "Ehh, enough already, let's not make a fuss and let's just make the campfire. Rather than us getting cold here, right?" Stella said.

  "Yes, I agree with Stella." Chloe added.

  "Okay then," Selene replied.

  Arthur dropped the firewood into the ground then raised his hand which then gathered mana around it and then...

  WUSHH

  In Arthur's grasp was now a fireball ready to light the bonfire. Arthur then threw the fireball into the pile of firewood which made the bonfire light up so instantly, without any effort at all.

  "Wow, your way of using mana is really cool. Okay, since it's already lit, let's all sit on the mat and rest." Selene said, which was then followed by those who were about to sit on the mat which according to Arthur, was so soft.

  "Selene, I want to ask more about this world." Arthur said.

  "Oh, about what?"

  "About the existence of immortals. Do they have levels or something?"

  "Oh, yup there is. Do you want me to explain it now?"

  "Yes, you may. Thanks for desired to explaining."
