Uncle Nine: Starting with double pupils, he turned his master into a zombie.

Double pupils, unorthodox methods, myriad realms, decisive and ruthless, fast-paced.
Li Yu transmigrated to a zombie world and was adopted by an old Taoist priest. He thought he could embark on the path of cultivation and live a carefree life, but he didn't expect that the old man wanted to turn him into a zombie.
Fortunately, the Creation Pearl has awakened. As long as it possesses spirituality, it can purify and sublimate all things in the world, and even merge them!
Purify and elevate yourself, awaken double pupils, and become a Yin Spirit Body!
From the Breath-Eating Technique to the Ghost-Eating and Demon-Devouring Scripture, from the Origami Technique to the Record of Countless Vengeful Spirits, from the Heart-Eating Hand to the Ksitigarbha Purification Great Hand Seal...
He killed his master and turned him into a zombie, thus beginning Li Yu's cultivation journey...
Uncle Nine: What do you mean by "a demon with double pupils committing evil deeds"? I'll reiterate: Fellow Daoist Li Yu is a heretic! And by the way, stay away from me, or I'll get blood splattered on me...
Four Eyes: Fellow Daoist Li Yu, let's make a deal. When I ask the Ancestral Master to possess me in the future, will you come instead?
Chizuru: I only play high-level games? I'm quitting, I'm done playing, running into Li Yu is a guaranteed death sentence...
Shi Jian: The world is in chaos, plagued by demons and monsters. Only the iron-fisted suppression of these evil spirits by someone like Chong Tongzi can restore peace! If you are willing to accept this offer, I am willing to lead Maoshan with all my might!

Countless years later, a great terror roamed the myriad realms, its double-pupiled gaze sweeping across countless worlds, causing the birth and destruction of countless realms.
"How dare ants glimpse the face of the heavens?"
