The proton of the Great Xia Dynasty, Li Changgeng, was demoted to Jiuyou Heavenly Prison because he was involved in a royal secret case, and he will never be able to stand up again. In desperation, I accidentally activated the [Three Thousand Gods and Demons Acting System]. The missions issued by the system are weird and bizarre, but the reward is the opportunity to play as an ancient god and demon. Each time I play a god and demon, I can temporarily obtain part of its power, and permanently obtain a fragment of the law represented by the god and demon.
