Everyone Transmigrates to a Cultivation World, but I Gain Immortal Eyes

[Everyone cultivates immortality + no saintly heroine + stockpiling supplies + Survival + self-interest]

One day, a hundred billion people around the globe woke up scattered across a perilous world of immortal cultivation. This otherworld had cultivation resources and powerful demon beasts, and everything came down to luck.

Yiluo was forced to take part, but fortunately, he had Immortal Eyes. They could reveal the weaknesses of his enemies and the uses of any item or living creature. He also unexpectedly obtained a servant-contract scroll, which could forcibly tame ferocious beasts of any cultivation level as his pets.
