Ryuu and Xingyue stood side by side on a vast green surface beneath them and observed the kilometer-high waterfall which gave off the feeling of the heavens crying.

Long Xingyue: "Hey bro..."

Asura Ryuu: "Mm?"

Long Xingyue: "How did father succeed in making this whole thing, it looks as if it was made by nature."

Asura Ryuu: "Well, it's not entirely his doing - there's an array beneath us but it's hidden very well. In my opinion, this might be actually an ancient item or something because one Spiritist alone even if it's the Emperor-level powerhouse can't make it from scratch."

Long Xingyue: "Oh. Little Brother is so knowledgeable, hehe. I'm the luckiest sister in this world."

Asura Ryuu: "Hehe, if you stick to me you will be as smart as me one day, I guarantee."

...

Long Xingyue: "Hey bro..."

Ryuu glanced to his side where Xingyue stood with an aura that pressured him a little and her voice became strange as if it was a mix of solemness, excitement, and a bit of fear.

Asura Ryuu: "Don't worry, we can do it together. We'll surely pass this trial as well as every other that comes after and we'll fulfill our part of the deal with father, Right?"

Long Xingyue looked to the side, straight at Ryuu's black-green eyes and shoulder-long smooth and silky hair which made her be breathless for an instant and she sighed in her heart - regardless of how many times she saw him like this, every time her heart would thump louder and louder the more she stared at that proud figure.

Long Xingyue: "Yeah, let's get this over with and move on. It's not fun being in this place anymore."

Ryuu and Xingyue observed waterfall some more, one of them watching its magnificence while the other thinking about how to pass the final trial for this area.

If someone knew the requirement these two seven-year-old kids had to face, they would probably curse the one who made them do it.

Ryuu and Xingyue had to stay under the 'Heavenly Waterfall' for a whole day without using their Spirit Energy, purely resisting it by their body in order to pass it. Can you even imagine how big of a burden it is for these children who hadn't even learned anything about the world to undergo such torture?

Of course, you can't.

However, Ryuu and Xingyue could because of their special circumstances:

- First and foremost, they are Spiritists who use Spirit Energy and under the nourishment of it, their bones, skin and even hair and cells undergo a qualitative change which makes their bodies pretty sturdy and resilient.

- Second, Ryuu's body is forged from the body of a True Heavenly Dragon which in itself is on par with Gods in terms of quality, but that doesn't mean he can just defy the laws of nature if he has the God's body in a lower plane. Why? Because its only Quality - meaning, Ryuu has to improve it himself and only the improvement rate and regeneration rate are increased. Practically, this means that if someone with a high enough cultivation used their Spirit Energy to attack unguarded Ryuu, they'd break his bones. But luckily, Ryuu trained his body to the max and as much as he could, he tempered it with his low Spirit Energy.

The problem Ryuu faced was only in Spirit Energy for now because he was stuck at the middle of his realm, not even knowing why he's stuck there, but Ryuu could never imagine that there's actually no problem and that it was Little Dragon who suppressed his cultivation speed so that he'd be able to focus more on tempering his body and making solid foundation without telling him.

If she removed the seal on Ryuu, he could instantly shot through the weak barrier between the realms and enter the next realm instantly, but that's not what his master wants to see because Ryuu chose the hardest path in cultivation without knowing the consequences fully.

- The third is that Long Xingyue has a special body that she got from her mother and her bloodline when her Sea Goddess Soul Spirit awoke under the influence of Ryuu's blood and aura.

With those combined, these kids could be seen as monsters for their age, it was just that they didn't know that yet...

-----

Later that day, under the moon and the stars, the two fully naked petite figures sat on top of the rocks straight under the waterfall which seemed to be falling straight down from the stars above them in the dark sky. The moonlight shone on the two, illuminating their bodies full of wounds and their skin pressured by the enormous mass of water falling at almost the speed of 300km/h at the constant speed. The force with which water is landing on their small bodies is equal to the force of one ton, going by how Ryuu calculated it.

The important thing which should be noticed is that in the past several months, Ryuu and Xingyue got very close to each other, that close in fact that they were used to sleeping while hugging each other as if they were one soul in two bodies, but that's just how it seems on the outside. During that time, Long Xingyue taught her little brother about the legends and the way of cultivation while Ryuu told her the stories from his past life on earth and, at the same time, taught her how to use maths, physics and other techniques which could help them greatly.

To Ryuu's surprise, this world didn't have any concrete system for units or heat or anything similar to what humans on Earth had. Let alone that, they didn't even know maths or the structure of this world. When Ryuu was explaining, Long Xingyue was gasping from shock after knowing the information which turned her short life upside-down. An example of that was the knowledge about celestial bodies and things related to the universe, or atoms, matter, energy types, laws. Ryuu had to explain all that and furthermore had to explain what some terms meant.

Ryuu noticed a strange thing over that course of time - the several years he spent in an illusion, his body actually entered the illusion together with his soul, which means that was something like an alternate reality, but that was only one of the things he found out. The others included the fact that he understood the language on this planet, that he could feel the Spirit Energy and Spirit Power. That was all thanks to the genes from the dragon's body which was reforged to fit a human's. When Ryuu thought about it, he decided to fulfill every wish of his from the past life and try out as many things as he wanted - DNA modification, exploring the universe, conquering the celestial bodies and so on.

While the two were fighting with their last ounces of energy under the force of water, they didn't pay attention to the outside world and only focused on defending themselves as well as sensing the state in which the other was in case something happens, that's why they didn't know that the dark black-green figure of a girl coated in mesmerizing scales and ten wings behind her back each having a different color observed them and prepared to help at any moment. Even though Little Dragon used her own body to forge Ryuu's and an enormous part of her strength was used up for precise control and resisting the laws of the universe when she 'revived' Ryuu, there was still some power left sealed within his body that he didn't know of. The reason he couldn't detect it was because Ryuu's master didn't use Spirit Energy and instead used a completely different type of energy based on laws, therefore her whole body had 'space pockets' hidden through it where she stored her energy.

In other words, there were several separate dimensions where her power was still preserved and in case Ryuu faces any danger, she can overtake his body for a brief moment and help him out without any damage or negative aftereffects, but that's only if it's for a short moment, else his undeveloped body won't be able to take it even if it's of a Divine quality because his Spirit Power is low.

As the black-green figure was observing the two, in Ryuu's Spiritual Sea some changes were being made. At one moment, Ryuu even felt that he almost broke through the 15th level and that made him excited. But that excitement got magnified by Ryuu's Soul Spirit and therefore Ryuu was now in an 'S' mode where he enjoyed being tortured by the waterfall because it gave him the chance to breakthrough.

At a certain point in time ...

*CRACK~!*

A sound similar to something cracking and shattering reverberated in Ryuu's Spirit Sea as his aura sharply rose and behind him, under the waterfall, a black sphere with ten colorful dragons appeared, greedily sucking the surrounding Spirit Energy in.

Ryuu's mind echoed with his crazy laughter filled with joy and extreme happiness as well as ecstasy.

"Finally! I finally broke through, hahahaha!!!", echoed in his Spirit Sea followed by the roars of the ten dragons as if they were cheering him on.

Even though Little Dragon was outside of Ryuu's Spirit Sea, she now had a constant connection with him and could feel everything that happened in his Spirit Sea if she focused on it.

Little Dragon: "This brat actually broke my restriction, what a monster..."

One had to know that in terms of Quality as well as Quantity, Ryuu's master had infinitely stronger Spirit Power than Ryuu, but with his will alone he broke the restriction she placed in order to suppress him.

However, Ryuu didn't know that by doing this he made his own life more troublesome:

"If he did it now, then he could as well do it in the future, which means... Hehehe. Ryuu, from now on every time you reach the point of breaking through, I'll place a restriction that you'll have to break by your own will as you did with this one. Hopefully, it will keep you restrained or else... you'll be short-lived. There are things that even I can't help you with and that is interacting with the world I made..."

Little man under the waterfall opened his eyes slowly as ten-colored light flashed in the depths for a split second before disappearing. When he felt the warmth coursing through his body, he knew that he actually broke through and entered a new realm.

Asura Ryuu: "21st level in an instant, what's up with this?"

Ryuu glanced to the side where Long Xingyue was and felt that her aura was slightly stronger than his. "Wait, how's that possible if we're at the same level?"

Ryuu found it strange, but when he inspected her, he found that she actually broke through several small realms and was level 23 right now, hence she was still stronger than Ryuu in terms of Spirit Energy.

Asura Ryuu: "Life is unfair to me regardless of where I go it seems..."

Just when he thought that he caught up with Xingyue, she actually left him behind again.

Asura Ryuu: "Well, nevermind."

At that moment, the heavy feeling from their backs suddenly disappeared and Long Xingyue opened her eyes. The first thing she did was to jump in Ryuu's embrace and congratulate her younger brother on breaking through as well as Ryuu returning the congratulation even though it wasn't the same. Only then did they notice that the waterfall was neither 'water' nor 'fall' anymore - it disappeared. To be precise, the water disappeared and everything else was still there. Only now, there was a bluish pearl suspended in the air before the two.

"The first trial - Body Tempering area passed. Rewards handed out. Proceed to the next area.", the voice which seemed neither male nor female appeared in their heads which made them jump with joy.

"We did it~!"

They inspected the pearl with their Spirit Sense and found that it contained some techniques related to the cultivation of the body. Ryuu helped Xingyue out with them because he didn't need any of them - his body was already cultivated to the peak rank of quality, he only lacked constant training in order to make it more sturdy which couldn't be replaced by techniques. There was a shortcut and that was to take some Spiri Pills made of the fruits or plants but neither of them knew how to do it, therefore Ryuu only observed the inner changes in Xingyue's body with his Spirit Power-related Soul Spirit while she circulated the technique and, with the help of Little Dragon, directed his sister how to increase the results,

The two of them continued cultivating through the night, but now they were dressed because they didn't need to go under the waterfalls anymore.

Even then, Ryuu found it mysterious how this enormous array supported itself and was able to do all of these things, but as he couldn't comprehend, he left it by the side.

Now there was one problem - Ryuu found that it's extremely hard to cultivate even with the help of the black sphere which connects to his Spirit Sea, but that wasn't only limited to himself, even Xingyue felt it hard to progress any further as they were both in the third realm - Spirit Core Condesing Realm.
