This is an era of high martial arts where monsters are rampant, ferocious beasts are raging, and demons are invading, just like the arrival of a mythical world! There are giant kuns thousands of meters high that swallowed up the Sakura Country and flew away in a hurry, there were giant pythons that were 10,000 meters long that wiped out the Australasian continent with one tail, there were magic ants that were 100 meters long that resisted several nuclear bombs and left without any damage... And Qin Shaoyu, who traveled through time, unexpectedly discovered that there was a game world inside his body. What was even more unexpected was that the character created in this game world turned out to be his clone. He also discovered that the clone upgraded in the game world and was able to synchronize its power with the real body. Some items in reality can be exchanged for various required gold coins, divine stones, divine powers, etc. In the game world. So in the game world, a big man who is good at playing krypton gold was born! "Master Qin defeated the Demon Emperor, won the first place in the Abyss Experience, and gained 100,000 reputation!" "Master Qin defeated Wuming, the Lord of Swords, and won the throne of the strongest man in the God's Domain!" "Master Qin broke through the 999th wave of the Tomb of the Gods and was rewarded with supreme magic weapons!" "..." In the real world, Qin Shaoyu slowly opened his eyes. The power of the avatar of the strongest man in the Dominion Domain within his body came out instantly and could easily tear apart the void and traverse eternity. With the power of the Supreme Overlord King, he can turn the world upside down, shatter the sky, crush the giant beasts in the starry sky, and tear apart the alien demon emperor with just a trace of his aura. As a result, the first existence in the world that was as mortal as a god appeared, leading mankind to kill through the entire mythical world!
