The Legend of the Dragon King: The Frostbound Boy

No one knows that the arrival of a mysterious boy from the Far North will upend their lives. He will become the greatest variable among them, the older-brother figure of their generation.

But whenever they challenge him to a duel, they all complain that his fighting style is too underhanded and ask for his soul skills to be banned.

They don't know that the boy's identity is another great mystery. Hiding the blood feud he carries, he goes by Mo and keeps up a cheerful front.

No matter what he faces, his motto is to fear nothing, even death. The word "madness" is carved into his bones. When an abyss appears in the Far North, he stands guard alone and never retreats. When his Martial Soul changes and evolves, the day of his revenge arrives.

"Leave none alive."

Tang Wulin: "Welcome to Moshuang An."

Xie Xie: "You can't tell me that isn't underhanded."

Xu Xiaoyan: "He's just using his abilities properly, not fighting dirty."

Gu Yue: "I hope you'll still be the same in the future."

Moshuang An: "How am I underhanded? I just happen to show up behind you sometimes."

They save one another, stop being insecure and become brave, and stop burying their secrets, turning instead into blades that protect others.

But in the end, he loses his emotions and is left with no choice, becoming the sharpest blade of all.
