The Invasion of Evil Tribes Where All the People Are Cultivating Immortality

I, Lin Tian, was originally an 18-year-old boy, but for some reason I got the memory of seven years later. Humanity at that time was on the verge of extinction because it was too cruel. I didn't know where the system came from. Faced with him, he found that cultivating every human being, the people here no longer have disputes. They just want to cultivate so that they can have abilities but kill everyone. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
