I Actually Became the Source of the Sequence

I thought I would be a new student after the college entrance examination, but I didn't expect that this would be the beginning of a nightmare! Yan He has cancer, and it's still in the advanced stage! I wanted to eat the fungus and poison it directly, but I didn't expect that not only would it be fine, but it would also secrete a liquid that could make ordinary items undergo extraordinary changes. He is saved! And an extraordinary era has begun! Plant breeders, clinic doctors, vampires, zombies, Taoist priests... Extraordinary things are rampant, and evil spirits appear! No one knows whether this is a reappearance of history or a lie turned into reality! Yan He didn't care about this, he just wanted to test the way to become a god. Later, an extremely powerful demon planet found the coordinates of the Blue Star and invaded directly. "Devil? Good material!" After he noticed it, he looked over excitedly. After a while, the devil shivered! I want to seal the space tunnel and escape from here! Yan He looked helpless, "You're already here, sit down, I'm very hospitable!"
