Demon Soldier Supreme

There are powerful alien demons sealed in the demon soldiers. It is said that those who pick up the demon soldiers have only two fates. Either they will be swallowed by the demons in them and become the incarnation of the demons who only know how to kill, or they can conquer the demon soldiers and become the strongest person in the world. However, the fate of most people... Is the former. Those who will become magic soldiers are either madmen or desperate people, and coincidentally, Li Xiao is both.
