I May Be Cultivating Evil Immortals

He died suddenly while working overtime, was a waste of time and time cultivating immortals, his right eye was shattered, and he was ostracized by his peers. The only abnormality is: the broken right eye can see the black cracks spreading on everyone's body - that is the sign of "evil transformation". Each level of the righteous cultivation method takes away an emotion. The so-called ascension is actually becoming the food of the evil god. The cracks on his own hands were golden. Everyone is the same, except him. A time traveler who "doesn't care whether he lives or dies", in a world where "you can't become stronger without making a sacrifice", who should he choose to be a sacrifice for? In other words - who should I choose to be the sacrifice?
