The Law of Webnovels - Chapter 513

Yang Dai, who was reborn in the third year of high school, was forced to enter the [Deep Domain] before he could be happy.

This is a world where gods and gods reappear and demons eat and kill mortals!

Myths are revived, animals and plants have been transformed into demons, foreign ghosts have invaded, and the status of human beings as the ruler of the earth is at stake. At this time, the mysterious [Deep Domain] came to the earth in the form of virtual games, bringing hope to mankind.

Yang Dai entered the deep domain to gain the ability to control the soul. Based on the concept of wretched development, he wanted to be a soul summoner, and he planned to form an army of souls first, and then explore the deep domain.

Unparalleled talent, the peerless genius of the dynasty!

The unparalleled demon king who is wreaking havoc on the world!

Covering the sky with one hand, the Patriarch of the Demon Dao who presses the right way!

When Yang Dai’s soul army appeared more and more terrifying names that shocked all beings in the two worlds, he also won the honorary title of Megatron.

Soul Master!
