Wang Jin traveled to the world of high martial arts invaded by alien beasts. Alien beasts invaded, and everyone had to practice martial arts to protect themselves, but Lu Jin logged into a lost fairy world in a dream, where he practiced fairy arts. The strongest breathing method on the blue star? Is it comparable to my Daojing? The strongest body training technique? Can it be compared with the body training supernatural power in the world of Xianxia? The expensive nourishment to replenish qi and blood? There is an elixir and a wonderful medicine, and one can increase life by a hundred years!... In the lost world of immortals, Lu Jin is the only heir to the lost immortal world. Waking up in a dream. One person with one knife, standing in front of billions of people. One knife, cutting out the universe!
