I'm Not the BUG Xianxia

"Brother, I just sucked some spiritual energy from you. There is no need to chase me!" Su Chen was originally a rich second generation. In a consciousness game called "Dongchen Xuanzhou", a real person who cultivates immortality, he was told by the system that he had traveled to a real world of immortality. At first he thought it was a joke, but when he actually saw someone having their aura drained, he realized that the system had not lied to him. In order to survive, he decided to find a thigh to hug him first. Fortunately, this thigh was not only thick, but also seemed to be very soft... But, why do you say that I am the source of trouble! Is time travel itself a BUG?
