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?

The apocalypse has not yet begun, but the system has arrived early.

Then Chen Mo’s style of daily life suddenly changed.

You can get rewards for eating and petting the dog, and communicating harmoniously with beautiful women is regarded as a battle with the ninth-level corpse king!

[It was detected that the host was so brave that he fought the ninth-level zombie king until he lost all strength. Since the target level was too high, the host could still get points as a reward even though he had not completed the kill by overstepping the level of the enemy. The host is hereby rewarded with 5,000 survival points and an A-level gift pack. 】

Chen Mo, who had just finished the battle with his schoolmate, couldn’t help but have a strange look on his face when he looked at the translucent floating window in front of him and the harmless schoolgirl beside him.

[It was detected that the host had tamed a fifth-level mutated corpse dog. Because the target level was too high, the host jumped over the level to tame the alien beast, which is unparalleled in charm. We hereby reward the host with 2,000 survival points, a B-level gift pack, and +50 charm! 】

Chen Mo, who had subdued a wolf dog with snacks, listened to the prompts in his ears and felt quite fucked.

Chen Mo lives a normal life, but in the eyes of the system, his life is full of monsters and ghosts.

This resulted in Chen Mo being able to trigger various rewards with every move he made. When the end of the world came, Chen Mo’s rewards would be maxed out, and his combat power was incredible!
