I'm so Good That I'm a Leader

Li Xuan is the leader of the Holy Realm of the Upper Three Realms in the universe. However, the disciple he regarded as his own son turned against me and killed me. Unfortunately, my life should not have been cut off, and I was reborn. The good news is I'm still alive, the bad news is the resources here are terrible. Fortunately, the memory has not disappeared. He also received the first mission in this world: to develop the sect.
