KO One: I Am the Legendary KO Zero

Chen Qian transmigrated into the Demon Realm of The Ultimate, where his body was taken over by his demonic second personality, "Zero."

With astonishing talent, he became the second demon in millions of years to reach the level of Demon Venerable, and challenged Demon Venerable Diabolo.

Before their battle could reach a conclusion, an accident sent him tumbling into the Golden Dimension. At that moment, Chen Qian, his original personality, awoke.

Having no memories of what had happened before, Chen Qian thought he had just transmigrated and was an ordinary person with no powers.

Then his System awakened, too.

Chen Qian had no idea he was already a fearsome Demon King renowned across the Twelve Dimensions. He worked hard to "make a comeback" with the help of his System.

Until danger arrived.

Arthur: "Chen Qian, run! I'm about to be possessed by the Sword Demon. You're no match for him!"

The next second: "Huh? Why is the Sword Demon kneeling to you?"

Black Dragon: "Hahaha, Chen Qian, become one of my living corpses!"

The next second: "Your humble servant pays respects to Lord Demon Venerable!"

In the end, Chen Qian united the forces of good and evil, bringing the Demon Realm and the righteous path under his rule.

The Flame Envoy: "Brother Qian is here. I'd better take the long way around."
