When otherworldly demons invaded, thousands of Heroes were chosen to enter a secret realm. Their bloody struggles against demon beasts were streamed live for the whole world to see. Unfortunately, I, Chu Mo, was among the chosen ones. But all the other Heroes are frigging cultivators! You want a normal guy like me to go fight demons? Are you insane?! Then, the sign-in system went online. On my 1st day of signing in, I got the power of a 1000 year old demom beast; on the 2nd, I received a legendary Martial Gods experience; and on the 30th day, I turned into planet-class one-punch man!
