Liu Xuan is a system player. The system allows him to travel through various time and space and improve the host's own abilities. The price is that he ultimately needs to do something for the founder of the system. The system is a serious system, but the host is not a serious system. The system was originally called the strongest cultivation system in the world. The purpose is to cultivate a strong enough host to do something. But Liu Xuan directly changed its name and changed it to the ten thousand world lewd stick system, which is in line with the facts.
