The same universe has the modern world and the ancient world. The two have different timelines. Four years in the modern world are equivalent to tens of thousands of years in ancient times. The male protagonist travels from modern times to the ancient world of martial arts. This world is based on the power of the mind, telepathy and magic as the core, and the master is respected. After the war between humans and demons, there were the orc clan and the five empires (Tianze, Ruiting, Ouying, Mancheng, and Xia Shang). The Tianze Empire fell due to the slumber of the strongest, and new types of human demons appeared in each empire. The demon cultivator who studied under the demon god Demon Fist Sal is the first person to cultivate demons. After the protagonist learns of his tragic fate, he and the devil return to his realm to find a physical body and change his fate. The demon cultivator shows determination and hard work, embodying the common humanity in different realms and times, and explaining that only by being strong can you change your fate and protect the people you love.
