The supporting character's harem is very normal - Chapter 236 Welcome home

During the demon-summoning ceremony, Aiwass finally recalled his past life's memories.This should be an online game that his family's company had released and operated for six years. Now, his foster father was the leader of the latest version's antagonist organization.He would expose his identity six years later, hesitate and then defect from the protagonist's side. Ultimately, because he decided to take a fatal strike meant for the player character, he was killed by his upright older brother in a transitional CG without even a chance to enter the main content.——But the problem was not too significant. Aiwass also knew many secret advancement routes exclusive to the player character, as well as the Nurturing Secret Sequel regulations of the various Paths. He believed he could reverse his unfortunate fate……So now there was only one issue left.“According to the original plot, shouldn't I have been rescued by the protagonist before this lousy ceremony even began?”Tied to the ceremonial altar as a sacrifice, Aiwass fell into contemplation.

An ultimate warrior, the one and only Alchemy Emperor, Ling Han, died in his quest to achieve godhood. Ten thousands years later, he, with the ‘Invincible Heaven Scroll’, was reborn in the body of a young man with the same name. From then on, winds and clouds moved as he set himself against the uncountable geniuses of this new era. His path of becoming a legend has begun once more. Of all eras underneath the heavens, I am the strongest!

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?

This is a story about the protagonist getting the system, going crazy in the biochemical apocalypse, producing aircraft and tanks, destroying zombies, saving good people and killing bad people.
