After Cole recovered from his excitement, he immediately started his long-term cultivation. Fortunately, with the scent of the Mind Calming Grass in the surrounding, the unwanted thoughts and distractions vanish almost instantly.

When he enter the cultivation trance, he run the [Dantian Genesis Cultivation Method] and the rich Heaven and Earth Energy from the Spiritual Spring flows towards Cole's meridian with a steady flow like a calm river.

He don't know the difference between the outside world and [Inner World] that makes the flow of the energy greatly different. Like on the outside, even without the [Messiah Tree Martial Spirit Skill : Breakthrough Aid], the energy that flows through him brought a little pain but inside the [Inner World], there is no such pain. It was very smooth that it brought and gave him comfort.

What is the difference between them? Was it because outside he absorb all kinds of energy that have a small incompatibility and therefore collides? While the [Inner World] only have one kind, attributeless energy?

Nevertheless, whatever the reason behind it, it just further prove that the [Inner World] is getting better than the outside world. Well, not as the whole but maybe much better than the Low Lands that only have a small amount of energies.

The rich energy from Spiritual Spring continue to flow and absorb by Cole. Also, one of the good thing detected is that the energy only pass his six colored sun, which later called by him as the Refinement Sun, and just like the name stated, it filters and refine energy to the purest form possible. This means that the energy from the Spiritual Spring is pure and almost untainted by impurities. It greatly hasten his speed of absorption.

This time, since Cole is facing a problem regarding with Space, he focus all the absorbed and refined energy into the his Space-Core.

However, two days later, eventhough he felt that his Space-Core are already full to brim and should already make a breakthrough, it did not. It was as though it was restricted by some kind of hidden restriction, which Cole didn't have any idea about. It seems that he have yet to master his Solar Formation System.

But he still continue on sending energy towards the Space-Core. He don't know what restriction it blocks to have a breakthrough but he knew that he'll trigger some kind of reaction which will solve his current predicament.

Just as he thought, five hours later, the Space-Core can't receive more energy. As he expected, he did encounter the strange reaction he was waiting for; all of the energy that he is directing to his Space-Core directed back and absorbed by the center of the Refinement Sun, where his Wood-Core preside.

One day later, with full of momentum, along with the assistance of [Messiah Tree Martial Spirit, Breakthrough Aid], his Wood-Core finally made a breakthrough and enter the Second-Level of Core Formation Stage.

And the very after the process finished, his Space-Core immediately follow and also enter the Second-Level of Core Formation Stage.

After this process, Cole conclude that as the center of his Solar Formation System, the Wood-Core should be the most powerful. Other Cores or his affinities can't exceed the level of it, which also means that he have to prioritize the growth of his Wood-Core among many others.

Knowing this crucial rule, Cole set aside the other elements and decided to improve his Wood-Core and Space-Core first.

Without any more thoughts and distraction, Cole fully focus on his cultivation.

One month later, his Wood-Core level-up to Third-Level. Three months for Fourth-Level, seven months for Fifth-Level... By the time his Wood-Core reach the peak of Ninth-Level, it was four years later. He only stop when the Wood-Core won't receive any more energy.

And for the first time on that four years, Cole finally open his eyes. The moment he did, a great pang of hunger immediately assaulted him. When he look at his arms, he could clearly see that he it was a literal skin and bones.

Although the Energy of Heaven and Earth is totally great and could do many amazing things, it was not omnipotent.

Yes, it could support him until now but it can't completely provide the mortal human body needs.

Without disturbing his tamed beast who also focus on strengthening themselves through meditation, Cole immediately teleported himself into the nearest tree that was full of delectable fruits.

The current [Inner World] finally reached it peak, the concentration of the Energy of Heaven and Earth inside are already very rich. All of the herbs, flowers and trees inside that was actually composed of more of low ranking items due to their origin, were all flourishing. The herbs and wild grass were all very healthy, the flowers look more vibrant and all trees were full of delectable and nutritious fruits.

Only, except for his tamed beast and creatures alike, there were no other within inside.

Cole focus on gorging himself with fruits that he actually finish that first tree in no time.

Cultivator's digestive system is very powerful. If the rank of the items they were eating has a low rank, they could digest it almost instantly and use the extracted nutrients into improving their body.

Cole's body, despite having a little feminine like body, are very powerful due to him being bath for the long time with Messiah Tree's aura. In addition, since all of the greens inside the [Inner World] were also bath with Messiah Tree's aura and were almost remolded into something perfect, they were almost with no impurities and also very easy to digest by any being.

It wasn't even an exaggeration to say that all of the greens inside the [Inner World] were all unique treasures.

With Cole's digestive system and foods' uniques factors, his skin and bones body are improving fast visible in the naked eye. By the time he finish the fourth tree, his body return to normal, healthy state. Only after he finished the fifth tree did he finally feel full and stop his feast.

Pity, there is no source of meat inside, much less outside. No matter how great the fruits inside are, both his body and soul are still looking for meat. It seems that he have to raise some livestock inside the [Inner World] for him to avoid this kind of situation in the future.

Wanting to check his progress, Cole summon [Gate] and appear beside the [Summoning Grimoire]. This time, instead of world of black ink like before, it was now a world of mist. He immediately felt elated; his chosen path is true! He was truly inside in some kind of loop formation! He was sure that this mist was the protective mechanism of the formation, and since he could already see them with his [Heavenly Eyes] by now, he's 80% sure that he could clearly by pass this mist by the time he reached Nascent Soul-Stage!

Ah, the rewards! The treasures! Eventhough he was trapped in this independent space for years, as long as he could receive a rich reward, it will still all worth it!

Without delaying more, Cole return inside the [Inner World] and once again return near the Spiritual Pond and cultivate.

This time, he focus on improving his Space-Core. With the improvement of his meridians with his last cultivation which lasted for four years, his cultivation of Space-Energy to the peak of Ninth-Level Core Formation-Stage lasted only for three years, one year less than the last time. He only stopped when the Space-Core refuse on receiving any more energy.

After that, he didn't immediately try to make a breakthrough to next stage, the Nascent Soul. Without even trying he knew, more or less, that there is some kind of restriction once again.

The [Dantian Genesis Cultivation Method] is truly great and knew that it was definitely a first-class, but it did really have a lot of restriction. With this thought, he can't help but bad mouth a little the system; why all those restrictions wasn't added when he bought the manual of the method?

As if responding to his thought, which appear like adding a salt to his wound, a series of messages appear on his mind;

Do you want to purchase all the additional information of Dantian Genesis Method? This action will cost 3 500 SP. Proceed?

Cole gritted his teeth. Fortunately, he was on break of his cultivation as he was pondering what kind of restriction he'll face when breaking through the Nascent Soul-Stage or he don't know what will happen to him when he encounter this teeth grinding situation while he was cultivating.

With a deep ache in his heart, he agreed and proceed, spending his hard earned 3 500 System Points all at once.

Purchase Completed.

Many strings of information flow in to his mind. After he sorted it out for good five minutes, he found the information he needed along with other answer to his questions before.

For instance, just like what he expected, the strange shape of his other energies are actually called sub-Beast Cores.

Any creature who is on the path of cultivation are only entitled to have one main-Core. If others have other affinities, they either form a one Core which could contain up to maximum of five different energies, and this is the usual method.

However, due to the uniqueness of [Dantian Genesis Method], each energy should have one, independent core each.

Also, his six-colored sun which he later called Refinement Sun actually called the Five Element Refinement Sun. Although it was called Five Element Refinement Sun, it was not limited to just the five main elements. It was only called like that since to form it initially it needed the five main elements.

Fire is responsible for removing impurities, Wood is responsible for making it gentle energy for easy absorption, Earth is responsible for further refinement, Water is responsible for transporting the refined energy throughout the whole formation system through mist form, while the Metal is responsible for protecting the whole Dantian for prevention from possible crippling.

If other energies reach the Core Formation, they could also add their own unique properties for improving the Five Element Refinement Sun.

Of course, there is also the information he needed, and that is in order to reach Nascent Soul, he have to make all the sub-Cores reach atleast Fifth-Stage.

After identifying the correct path, Cole immediately return on cultivating. This time, his focus is to make his four sub-Cores – fire, earth, water, and metal – into Fifth-Stage. With the improvement from his last cultivation along with Messiah Tree's passive ability [Breakthrough Aid], he made it all happen for one year.

Without bothering on taking break, he switch and directed all the refined energy into his Wood-Core. This time, not the same as before, his Wood-Core received all the energy.

As if on cue, the rustling Messiah Tree Martial Spirit appear on top of his head. Seconds later, ten [Beast Phantoms] are summoned from void, with nine of it releasing a green radiance and one with red, fiery glow.

Nine of the phantoms position themselves in the air and began absorbing energy which are transferred to Cole while the other one flew towards the Fire Lizard.

A torrential flow of energy immediately follow. It was great since it was as though ten person are cultivating all at once but his meridians is not that much.

His Wood-Core is already full of energy from before and with all the rich energy continuously flowing into it, it was so full that signs of cracking are started to appear.

However, instead of feeling bad, Cole feel elated instead.

Base on the information he read before from Five Element Sect, cultivators Core is like an egg. In order to reach the next stage, the Core are needed to be opened and hatch what is inside, which is the Nascent Soul.

With the continuous flow of rich amount of energy, the cracks on his Wood-Core increase and when it reach the peak, instead of big explosion like what he's expecting, the Wood-Core open slowly. With all the wonders, it literally look like a opening lotus flower made of green jade.

When the lotus flower bloom fully, there sat in its middle a miniaturized image of him in meditation posture. It was 100% looks like him except having a green hair and luckily, genderless...

Cole continue to send energy towards the Nascent Soul to stabilized his Stage, and by the time the [Beast Phantoms] vanish, he knew that he is successful... He's now a Nascent Soul-Stage cultivator!

Still basking on the feeling of success and striking the iron while its hot, he immediately follow his Space-Core.

This time, it was a little different; it remained a Core but on the inside is the miniature size turtle... Yes, the transition of his Space-Core to Tier-4 is also successful, almost without difficulties, but instead of image of him, it was Shelly...

Oh, well... He already have a sub-Beast Cores, having a beast Nascent Soul is not a big deal anymore!
