I Will Be Immune to All Poisons in the Last Days

"The end of the world + no system + no powers + no rebirth" In the apocalypse, mankind is forced to evacuate to the deserted island to survive. I was the only one left in the whole city. I thought I would die just like that. I didn't expect that when I was working as a drug tester, the vaccine I was injected with was a vaccine against apocalyptic mutated viruses! I was empty-handed and had only a small three-wheeler for company. It was also Xiao Sanlun who witnessed me. Make me the king of the new order in the last days!
