MTL - Pass Through 80s: A Notoriety - Chapter 27 really can't please

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?

Jin-woo had never considered himself someone ordinary. Okay, that sounded like an arrogant thought to have, but he was definitely unordinary. He would always be reminded of this whenever he had to take his antipsychotic medication for his schizophrenia. It also didn’t help that he was starting High School with the whole school knowing this fact because of his little… slip up? Of course this comes with bullies targeting him, but that wasn’t new. Jin-woo was determined to do his best to avoid them and not draw any unnecessary attention to himself… But that was impossible as some God seemed to have cursed him to be in the same class as his bullies, and even that nosy popular girl who won’t stop talking to him in front of everyone. How many times did he have to say they weren’t friends, much less childhood friends for her to leave him alone?! However, what might be worse than being in the same class as your bullies and that annoying girl, was being in the same class as your bullies and that annoying girl, while being trapped in there because of a zombie virus outbreak… and somehow being the cause of it? Should he stay, or chance it with the hordes of zombies outside? What would you do?

A few decades ago, many strange gates appeared all over the world, and a creature called a demon by humans also descended at the same time, bringing unprecedented catastrophe to the human world. Humanity has a chance to breathe.

By chance, the world’s No. 1 magician gave up his identity, became a rookie tester and started again, entering the mysterious gate to participate in those unimaginable trials.

“This is also considered a newcomer?” The testers were depressed.

Completed the novel “Sword Suit” with 3 million words, “Shen Pin Dao Sheng” with 1.6 million words, “Super God Gene” with 7.3 million words (in the comics update), and “I just want to play games quietly” (in the comic novel update).
