The World Core was in a crystal ball form. It was a mixture of world energy, dao concepts and world authority.
Fortunately for Mo Shen, the will of the world had long died, and the energy of the core had greatly reduced from how it was initially. Otherwise, the first obstacle to his goal in claiming the world for himself would be the will of the world. If it was still living, it would have destroyed anyone who had ill intentions towards its world, including Mo Shen.
The wills of worlds usually differ in strength. For a middle level world in the Dao Universe, the will of the world might have strength ranging from Universe Dao realm to the Universe Lord realm. But the only thing they can use their strength for is to protect the world from being destroyed. Even if invaders from outside the world wants to kill everyone in the world, there's nothing the will can do, except the invader attempts to destroy the world itself.
Usually in case of world invasion, the will of the world might be able to predict such circumstance and try its best to produce great talents and strong cultivators to face the future invasion. It's form of doing this is to instill part of its powers in form of talents when babies are born, and create oppurtunities for them to attain greater strength.
The oppurtunity can be in form of them being born into a powerhouse of that world, or in form of luck where they can have an accident and stumble into an ancient cave containing great resources. It can also be in the form of a great master taking them as disciples.
Mo Shen was sure that he wasn't one of those privileged ones. After all, his existence was one that could surpass the world and devour it. No matter how a world loves its residents, it would never create a variable out of their control. He could be said to be a special existence. In fact existences like him would usually be destroyed by the world.
The destruction would usually be in form of a tribulation during breakthrough. The will of the world can tap on the Heavenly Dao to increase the level of tribulation faced by the cultivator. It can also be in form of bad-luck, where the cultivator would never stumble upon oppurtunity, but dangers would be all around him.
Mo Shen emptied all thoughts from his head and put his hand upon the crystal world core. As he activated his 3 dao of Infinite Space Dao, Dark Void Dao and Billion Stars Dao, their aura flowed into the world core and provided a passage for him to absorb the world energy, authority and concepts.
As he was absorbing it, he saw noticed that there was a supreme dao in the world core. It was the Water Authority Dao. All elemental worlds contain their Authority Daos in their world core. He also just found out about this as he searched through his memories.
It was no longer a surprise that the will of this world perished. The world was initially a water elemental world, but suddenly an overpowered fire was introduced into it. It was normally said that water could counter fire, but reverse was also the case. If water comes into contact with an overpowered fire, then it would be devoured.
Mo Shen happily focused his attention on the Water Authority Dao to comprehend it. It was going to be his 8th dao. He was now one step closer to his goal of comrehending the 3000 supreme daos.
It took him 6 months to finish devouring the world core and take control of the Undying Phoenix World. It would have taken a shorter time if not that he was also comprehending the Water Authority Dao, in which he did in 1 month.
He felt the world energy in his body. It seemed like he didn't even need to pass through the Immortal realms, he already had World Energy. When he succesfully creates his dao, he could enter into the Universe Dao realm automatically. His cultivation path was truly different from the rest of the world. It was unique, not a path that could be imitated because it was born from his various experiences.
As he was examining his body, he felt an energy wave from another part of the world. "It seems like Mo Fan is about to break through to the Empyrean realm."
When Mo Fan left the Dao Universe with Mo Shen, he was at the peak of the True Immortal realm, shortly after he broke through to the Heavenly Immortal realm. Through Mo Shen's guidance, he was able to break through to the 4th stage of the Heavenly Immortal realm in these 17 years, especially with the 10 years he spent in the Undying Phoenix world waiting for him
And before Mo Shen started devouring the world core, he had given a part of his 5% crystal, which he used to forge his body, to Mo Fan. The crystal was able to take his cultivation to the Empyrean realm.
"It seems like he wasn't able to absorb up to 90% of the crystal and ended up wasting the remaining, and now, he still needs more energy to breakthrough." Mo Shen said as he appeared where Mo Fan was. "Let me give him a hand."
As he was now the owner of the Undying Phoenix World, Mo Shen had full control of it. He controlled the energy in the world to flow to Mo Fan.
Mo Fan was able to absorb 90% of the crystal liquid, giving him a chance to breakthrough to the Empyrean realm. As he discovered the wave of energy flowing to him, he knew his young lord must have succeeded in refining this world. Immediately, he started to absorb the energy wildly, using it to integrate his world energy into his body.
The process went too smoothly that Mo Fan even suspected something was wrong. Then when he thought over it once again, he knew it was to be expected. After all, he had entered the dao, and his understanding had greatly boosted his immortal soul leading to a smooth breakthrough without any obstacles.
Now the final step was the Heavenly tribulation. The first tribulation a cultivator will receive was when he was entering the Void Immortal realm. There were 18 strikes of the thunder tribulation at this point. The tribulation also had 9 levels depending on the potential of the cultivator. The 9 levels were represented by 9 different colors of thunder from the lowest: yellow, red, orange, blue, green, purple, black, white and gold.
The last time someone with the white tribulation appeared was millions of years ago, in the era of the Demon ancestor and ancient god ancestor. Now in recent times, those who are able to achieve the purple tribulation were referred to as geniuses of the era, and only about 3-5 of them could appear in 100,000 years.
Mo Shen was curious as to what the colour of Mo Fan's tribulation will be. Mo Fan told him that his last tribulation, when he entered the Void Immortal realm, was purple in colour. Mo Shen knew that in the short 17 years Mo Fan had followed him, his talent had improved greatly, especially when he had once used his ancient god blood as medicine for Mo Fan to heal his hidden injuries. He had also allowed him to absorb his blood a few times, when he was just short of energy for a breakthrough.
"Black thunder?" Mo Fan looked up in surprise. "Haha! My talent has undergone a terrific change."
"Use the thunder to temper your body, don't just block it out. These 18 strikes of thunder will be very helpful." Mo Fan heard a low voice transmitted to him. He knew it was his young lord who was unfathomable.
Without answering, he channeled his true energy that was converted from world energy to mix it with the thunder and absorb it into his body. Although it was very dangerous, but he knew the gains outweighed the losses. He might only feel injured for a while, but the tempering will bring his body to a whole new level. If possible, he could even use the remnant energy to breakthrough to the 2nd or 3rd stage of the Empyrean realm.
Bang!
Another strike of black thunder landed on Mo Fan. He gritted his teeth and endured it, allowing all of the thunder energy to enter his body.
Mo Shen sat cross-legged as he watched the scene. In his mind, every other thing had been shut off, the only thing he could see was the thunder. In fact he was even seeing more than the thunder on the surface, he was looking at the essence of thunder. Be it black thunder, or golden thunder, they were all the same to him right now. He was seeing the formation, movement and attack of the thunder strikes.
He didn't know how long he stayed there for. Even after the 18 strikes had been completed, thunder could still be seen his eyes. He remained there for a month. In his mind, the formation of thunder could be seen as he replayed it millions of times.
"Got it!" Mo Shen said with excitement as he stood up. He looked over at Mo Fan who sat cross-legged cultivating. "Oh, you've broken through to the 2nd stage of the Empyrean realm."
"Yes young lord." Mo Fan said as he opened his eyes. "You've been out of it for a month young lord. Don't tell me you just comprehended the thunder dao?" Mo Fan asked suspiciously.
Hahaha!" Mo Shen laughed happily. "Indeed, with a stroke of enlightenment during your tribulation, I managed to comprehend the Thunder Tribulation dao, although it is just at its entry level."
Mo Fan looked on without a change of expression. "As expected of you young lord. You really don't let any opportunity slip by."
"It's time to return. We've spent 3 years more than the expected time. I hope mother doesn't worry too much." Mo Shen said as he created a portal and left the world with Mo Shen.
As they got outside the Undying Phoenix world, Mo Shen stood in front of it. Utilising the power of the world core, he made a suction force towards the world. The world that looked to be over 25,000 miles round shrunk to the size of a fist.
Mo Shen held it in his hands as he examined it. It was only Mo Feng that was inside the world. He had been cultivating since they arrived there. He was presently in the Void Immortal realm. He was originally hatched with an Immortal soul, so from the moment it came out of its egg, it was in the Divinity realm.
"I'll call it the Small Crystal world." Mo Shen said. Then the crystal world turned into a light and entered the space between his brows.
Each cultivator at the divinity realm are able to open up a personal space in their bodies where they keep their artifacts that are bound to them.
"Let's go." Mo Shen said as he created another portal. He and Mo Fan entered it and flew forward.
Mo Shen wasn't sure of the approximate location of the main Dao universe, so he could only speculate it to be the area with the most spiritual energy in the void.
It took about 5 days travelling to different portals before they arrived at a world which seemed different from the Undying Phoenix world. Other than it being over 100 times larger, it also seemed perfect without flaws and complete. It overflowed with the aura of the dao.
"What on earth?" Mo Shen almost cursed out loud.
It was his first time being in the Dao Universe main world like this. When he first left, although he was already sentient, he didn't really know anything.
