Endless Apocalypse: I'm Really Not a Weird Killing Machine

My name is Jiang He. When you read this sentence... I should still be alive and well. I may have made a lot of money, paid off the debt left by my parents, and lived a good life with my sister... Once traveling through time, Jiang He came to a strange apocalyptic world. This is a weird world. In order to survive, the cursers and temperers have built island-like protected areas. Due to some rules, the weird outside world can't seem to invade the safe zone? But it doesn't seem to affect the strange births in the protected area. Fortunately, these are not things that a poor guy like him should consider. In order to survive in this apocalyptic world with his sister, Jiang He followed the footsteps of his master and embarked on the road of being an escort in the restricted area. He thought it was an endlessly dangerous path of no return, but he changed after killing a weirdo. It seemed that by killing the weirdo, he could extract entries and become infinitely stronger. … "Hey, don't you really think... That Jiang He has become more and more cruel recently? Several A-level weirdos were slaughtered by him. I heard that not even ashes were left at the scene," After saying that, he gently scratched his neck with his tentacles covered with sarcoma. "Now they all say that Jiang He is a weird killing machine!"
