“The mad dragon who crawls out of hell will stain the sky with blood!”
Qin Feng was once the world’s top mercenary, known as “Dragon Fang.” Framed in a conspiracy, he was thrown into the most terrifying prison on earth: **Death Prison**. It held SSS-ranked criminals: drug lords, arms dealers, hacker kings, underground boxing champions, and more.
Yet inside the prison, Qin Feng awakened a mysterious bloodline, befriended a reclusive medical sage, and brought all kinds of madmen under his command, becoming the uncrowned king of Death Prison!
After his release, he led a “Mad Dragon Mercenary Corps” made up of Death Prison inmates, sweeping through the world’s dark forces, taking revenge on the mastermind behind the conspiracy, and ultimately reaching the pinnacle of the world!
