The hidden dragon stirred from its sleep, the fierce tiger descended the mountain! Ye Wudao, following his master's orders, crossed into the mortal world, his medical skills so advanced they could reverse fate, his divine magic alone dominating the universe.

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?
