The four different types of energies were doing their jobs as Ye Xiao's focus was fully on them.
Some of the small pieces of his shattered world had already evolved to the size nearing his previous Small World. The biggest star in the Solar System was still the sun as it has already evolved to the size of Ye Xiao's previous Small Planet and was still evolving.
The spirit energy from the surroundings was about to run out but still, Ye Xiao failed to think of an idea. If he chose to go out of the Nature's Chakra to devour the Spirit Energy, he will lose the Yin and Yang Energies but if he didn't do so, the evolving worlds inside the Solar System will stop evolving and start to crumble, after all, they had yet to completely evolve.
If Ye Xiao wanted to create the Solar System successfully, he needed all four types of energies and if he lacks even one of them, he will never be able to create the Solar System no matter how hard he tried.
Ye Xiao could feel that the most lacking energy among the four energies was the Spirit Energy. It was not in terms of quantity. Quantity was the main problem but the quality was also important. Ye Xiao could feel that even though the Spirit Energy he was devouring was much denser than what he felt in the Outer Sect of the Dragon Immortal Sect, but its quality was still lacking compared to the other three energies.
Yin and Yang Energies were called extreme energies not just for the show. Their destructive power was incredible and this destructive power comes from their quality. The significance of the thinnest Yin and Yang Energy was much higher than the dense Spirit Energy he felt in the Upper Realm after he opened his eyes for the first time here.
As for his Soul Force, there was no need to say anything about it. There is no one under the Heavens whose Soul Force can match Ye Xiao's Soul Force in terms of both quality and quantity. After all, he had no normal soul but the Ancient Emperor Divine Soul and because of this, his Soul Force was also now called Ancient Emperor Divine Soul Force.
The only energy lacking in terms of quality was the Spirit Energy. Let alone equal, its quality was so low that caused the evolution of worlds to slow down to the extreme.
Well, Ye Xiao was already troubled over the matter of how to devour more spirit energy after emptying out the surroundings spirit energy, so he could not dwell over the matter of its quality. It would be already enough as long as there was spirit energy for him to devour until the creation of the Solar System.
"Damn it!"
Ye Xiao cursed out loud the moment he felt that he had already emptied out the surroundings spirit energy. He can not even leave the Nature's Chakra because if he did so, he could not continue to devour the Yin and Yang Energies.
"What should I do, what should I do? Damn it, damn it!" Ye Xiao became extremely anxious. There was no solution to this problem. It was already very hard for Ye Xiao trying to create the Solar System.
There was only a 30% chance of him being successful not just for any reason. The difficulty was really very high.
Let alone creating a Solar System, Ye Xiao believed that there was no one who had even thought of creating two Small Worlds instead of one. The way of thinking of everyone under the Heavens was the same. They had only one dantian and could only evolve it onto the Small World.
Even if one wants to create two worlds, they would never find a way because of having only one dantian. What is more, they were not crazy enough to try to destroy their Small World before creating many more Small Worlds.
First, they did not even know how to reform the Small World after its destruction. Ye Xiao was the only anomaly.
Second, they were not like Ye Xiao who had seen the complete process of the evolution of the Universe.
It can be said that under the Heaven and Earth, Ye Xiao was the only person who even thought of creating a Universe. Although currently, Ye Xiao was only trying to creating the Solar System, there was no doubt that after his success, he will continue to let the Solar System evolve and evolve until it finally evolves to being a Galaxy and then he will do the same with galaxy until it evolves into the Universe.
This Universe will be his own Universe, not the Universe that was in his mind or the Heavens.
At that time, he will be the creator of the Universe and the sole ruler where only his order would be the royal edict and no one could interfere in his decision.
Although there was already a Universe in his mind and Ye Xiao was its inheritor, Ye Xiao knew that he could never completely control this Universe because the Universe in his mind already had its free will and spirit. How can an existence like that be willing to acknowledge Ye Xiao as its master and give complete control of the Universe to him?
It was simply impossible.
Although this was all Ye Xiao's own guess, Ye Xiao believes that this guess of his is the closest to the truth.
Seeing the process of the creation and evolution of two universes was extremely beneficial for Ye Xiao's plan of creating his own Universe. At least he knew what he has to do.
In the end, his Universe will be under his control unlike the Universe in his mind where he had no control (at least for now).
Creating a complete Universe was a very long process. Ye Xiao had seen that even the natural evolution of the Heavens and the Heavenly Pearl into the Universes took a very very long time, more than hundreds of thousands of years or even millions of years, Ye Xiao was not sure. But one thing he was sure of was that the Universe he wants to create will also take an extremely long time. He will not be able to evolve his Solar System into a Universe in the near future but far in the future.
For now, Ye Xiao only wanted to create a Solar System but creating the Solar System alone was so difficult, difficult to the point where he has already run out of Spirit Energy and he didn't know what to do next.
Ye Xiao closed his eyes as he didn't want to see the evolving Solar System crumble into nothing.
But at this moment, Ye Xiao felt a fluctuation of energy from the Universe in his mind, and not long after, streams after streams of extremely pure liquified energy entering the Solar System without him needing to guide, and slowly replace the job of Spirit Energy.
This energy was so pure that its quality was not lacking in the slightest compare to the Yin and Yang Energy. Maybe, Its quality was purer than the Yin and Yang Energy.
Ye Xiao was left dumbfounded as he never thought that in the end, the one helping him would be the Universe in his mind. The streams of energy that it was sending were actually the True Essence Ye Xiao felt and saw at the Third Floor of the Nine Story Pagoda.
Anyways, it was a timely help. Ye Xiao needed this the most. Ye Xiao knew that the True Essence was the most purer version of the Spirit Energy that also exists in the air of the world.
It can not be found on the Lower Realm and the Upper Realm because both can not endure the heavyweight of the True Essence. Ye Xiao had already found from the memories of the three ancient gods that True Essence can be found only at some special places on the Upper Realm.
There was no existence of the True Essence in the Lower Realm.
Ye Xiao had seen when the Heavens evolved into the Universe, there was only True Essence everywhere. There was no existence such as the Spirit Energy. Ye Xiao didn't know what happened that caused the True Essence to almost disappear from the surface of the Lower and Upper Realms of the Heavens.
No matter what, that reason must be very terrifying which could cause the disappearance of the True Essence and appearance of the Spirit Energy.
Ye Xiao even felt that that reason might be related to the Heavenly Pearl in some ways which was now the Universe inside his mind.
No matter what the reason, it was not something Ye Xiao should be concern about. At least, not for now!
Now that the problem of the Spirit Energy was solved, Ye Xiao fully focused on controlling the other three energies well. There was no need for him to control the True Essence as it was being controlled by the Universe in his mind and was perfectly doing its job.
