I Have an Agreement with the Demon King

Three days ago, the family ancestor died unexpectedly. Enemies who had been dormant for many years came out in force, burning the house and staining the ancestral hall with blood. The Zhao family's century-old foundation was turned into scorched earth in a matter of days. His father protected him with his life, pushed him out of the pile of dead people, and spent his last breath, leaving only one sentence: "Live on." He was seriously injured and fled into the Warcraft Mountains, thinking he would die. When he was on the verge of death, in a desperate situation, the peerless demon king crossed over and entered his body with his remaining soul, saving his life. There is only one condition - within ten years, collect all the "Demon Emperor's Orders" scattered in the Demon Court in ancient times. At the end of the ten years, the Demon King will get back what he promised, and by then his soul will be gone.
