Reborn as Mr.CEO's Fat Wife - Chapter 414 - Bittersweet like Love

Tang Hao was an honest man making an honest living, but despite all his honesty and kindness, life often looked the other way. Even when he stood up for a man in the streets, he ended up being beaten to a pulp and the man he stood up for? He disappeared. That left Tang Hao with nothing to prove and a hefty medical bill blowing through his savings. However, while he lay unconscious in the hospital, he could feel a warmth coming from the jade pendent he wore as it began to feed him with a trove of priceless information. Now discharged, and still armed with the same naivety and honesty, what will our village peasant do with this newfound power? Will he go on to conquer the hearts of a hundred women? Will he defeat the mightiest crime lords? Only time will tell, but for now, fate has many whimsical plans for Tang Hao.

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.
