Douluo: Emerald Poison Emperor - Chapter 57: Douluo: Emerald Poison Emperor []

Being reincarnated in a cultivation world, Han Jue realizes that he can live his life like a video game. He can reroll his cultivation potential and connate providence.

Perhaps it is the choice of fate. As a senior otaku, Qian Lingfeng got the “steel shell system”. However, when he swept the world with the system, became a local rich man, made all kinds of beautiful women, opened a harem, and realized the ultimate fantasy of thousands of otaku, he found that things seemed far from simple!
When the end comes, biochemical zombies suddenly come down, fierce beasts are in power, bloodthirsty zerg roam to kill the world, and human lives are comparable to dirt. Where will weak human beings go in this world? Is humanity going to be extinct? Or … can an otaku save the fate of the human race?
