The Legend of the Demon Martial Emperor: An Isekai Cultivation Adventure - The Legend of the Demon Martial Emperor, #5

In the Yi family of Hongcheng city, Yi An was an insignificant member, but after his father's disappearance, Yi An and his mother suffered bullying. Until three years ago, when an accident occurred, the real Yi An ceased to exist. The current Yi An is actually a devil cultivator who has crossed over from another world. After three years of tempering, he rose from the ruins. With the body of a devil cultivator, he broke free from his shackles and looked down upon all others...
A young devil cultivator, reborn into this other world. Here, his brilliance soars again. No devil is too formidable, no devil too fearsome...   ---   The existence of this protective layer made it extremely difficult for him to immerse his mind and operate within it. The Island Guardian had once opened his eyes to glance at Yi An, then ignored him thereafter, tacitly allowing such behavior. Perhaps he knew of Li Mo Island's formidable nature, letting Yi An explore freely. Having once felt the universe and observed the mysteries of the cosmos, Yi An's longing for Li Mo Island's marvels grew stronger.
For several days, he sat motionless on the ground, his mind a blank slate, already deeply immersed beneath the earth.
