People Are in Fantasy, and They Sign into the Immortal Desolate Demon Holy Body at the Beginning

Fang Chen traveled to a fantasy world. Unexpectedly, after joining the sect, before he had time to practice with his master, the master broke down and he was the only one left in the entire sect. Facing the unfamiliar fantasy world, Fang Chen panicked a lot. What should he do if he has no strength? Fortunately, he awakened the system. Just sign in and you'll get something! The Holy Body of the Immortal Desolate Demon, the Dao Heart Demon Seed Technique, the Soul-Eating Banner of the Seven Evils Burning Heaven Forbidden Method, the Blood Evil Shura Palm, the Shura Demon God Sword, and the Three Corpse Brain Pills... Looking at the rewards he received for signing in, Fang Chen felt that signing in was not a serious thing, right? Thousands of years later... The strong human beings formed the Demon-Slaying Alliance and surrounded the Blood God Mountain. Fang Chen looked at the densely packed enemies and let out a sigh.
