The Black Dragon was slain in front of Wang Ling and the chains the thorns that slew the Black Dragon erupted from the ground and caused tremors that shook the entire realm.

The tremors were strong enough to affect the entirety of the two layers. The first and two layers are worlds apart. Different dimensions that exist outside each other's borders.

But despite this simple fact, the tremors were resonating with the roar that lies in the depths of the Black Dragon's world.

Curiosity struck Wang Ling but instead of sticking around to find out what caused the tremors, he began to run. He escaped through the way he entered and the left the three Devils behind.

The three saw him leaving and in a hurry, they called out, "Wait for us!"

He ignored them and jumped into the waters. He opened his feathery wings and activated his God's Mark. The God's Mark spread to his wings, although it was just the tip of his wings when he flapped them he zooms out of the entrance.

Wang Ling turned around and saw the three Devils in a frantic escape; alas, they too were slain by the thorns of the mysterious beings. They screamed in pain but it soon died down as the flame of their lives died down.

The thorns seemed to be hungry for life and it dashed towards Wang Ling and attempted to kill him too.

Raising his hand, Wang Ling brought out Reaper. His sword qi erupted with his killing intent. He slashed out and the only thing his sword could do was create a small time frame for him to escape.

He began ascending the next moment he got. Without wasting any time he moved like lightning, the thorn was coming for him and right in front of him as of this moment was a group of Oceanic Beast.

After all these years, these beasts have yet to give up. They opened their jaws and got ready to devour Wang Ling. But Wang Ling did not have to hide his hellish qi in this place, his qi erupted and his body exudes a dangerous aura. He swung his blade and more than ten of the Oceanic Beasts was slain without any mercy.

He passed the Oceanic Beasts and the thorn followed closely behind. The thorn killed anything it passed, it didn't care if it kills a beast, it killed everything that got on its way.

Wang Ling drew everything he had. The God's Mark was slowly eating its way on his body, the power of God's Mark was actually capable of corrupting his tempered body.

The power it held was too immense for him. This is the obsidian grade God's Mark, it was no ordinary God's Mark like the devil had used previously.

"This is a little difficult to use." He complained, "Suzhen, heal my wings, and the corrupted areas, make sure I don't die from my own doings. Fer, try your best to slow that thorn down."

"Yes, Father." Both of the Flames answered.

Wang Ling felt a warm flame entering places all over his body alleviating the pain from God's Mark's corruption. And around him were spear-like black flames forming, the flames of Fer burned with high intensity and soon it flew out to the thorn with the intent to stop its advance.

Boom! Boom! Boom!

Explosions echoed as Fer's flames fought back against the blackkthorn. Wang Ling had no time to actually observe the fight as he was too busy running away. The strength of that thorn was too immense, he can't deal with it for now.

He continued running and with his endless supply of qi and vitality, he didn't run out of qi allowing him to continue without rest. This continued for three days, straight, but when the fourth day came, Fer run out of his personal supply and he asked Wang Ling if he can draw out qi from him.

He had to think twice, Fer's managed to hold back, albeit it was only by a little bit the thorn from reaching him. But his decision was made quicker than expected, because the pressure of the thorn increased shortly after Fer's bombardment stopped.

"Do it, take as much as possible. I can get back what I lose so do not worry about it too much."

Fer did what he was told, and Wang Ling was put in a predicament. The usage of qi was too strong, even with his absorption, Wang Ling was being sucked dry by Fer.

Having been like this, he was presented with two options; first improve his cultivation right here right now, and second improve his bloodline to True Devil Emperor. He chose the easier and faster method, he chose to improve his bloodline.

From his forehead, he dug into the Blood Hell Pearl and drew out the bloodline of the devils that coalesce into a small fingernail sized blood. The blood seeped into his body but cut it off soon after.

The blood of the ancient devils flowed into his bloodstream and mixed with his own. The blood began to twist and turn, mixing and twirling like a snake that had found its mate.

The blood of the devil was surging with power. A dam-like burst surged in his body and flowed towards his back. His back began to burn as if acid had flowed into it, as if struck by lightning he felt shock flow all over his body.

It started from his back until it reached all the way to his toes. His body was changing. He was feel it, he needed to find a place where he can fully transform.

But, he can't do that right now. He is trapped, he has nowhere to run but ahead, change course to find a place to hide and he will find himself at death's door. He can only move forward, so he will transform whilst moving forward.

Underwater, he was swimming yet he was also soaring. Like a Koi emerging successfully from the bottom of the waterfall, he called upon the power that stemmed from his inner self, calling the wings that will let him soar to the high heavens.

A single black feather emerged from his back, and finally, it sprouted as if he was pulling the root of a tree. He cried tears of blood, the circle around his pupil sunk into it and turned it full crimson.

The fourth crimson ring emerged slowly and with the emergence of the fourth ring of the Piercing Vision, he finally escaped the cocoon of the True Devil King and emerged as a True Devil Emperor.
