The End of the World, I Am a Warhammer Greenskin Orc

What, the earth has been reduced to an experimental site for other civilizations, so alien viruses have been released. Why does this virus lead to evolution? I was having sex, but before the experiment started, the protagonist had a hemorrhoid rupture and was about to die. I couldn't bear to accept it. Ah, the experiment manager saw me as pitiful and saved me, revived me, and told me a bigger secret. All of this was actually to start the Xinhuo Project and create even bigger boosts. Hahaha. Fortunately, I drew the little green skin as compensation. Wuhu is about to take off!
