The Trapped Dragon Breaks Free from Prison

Su Mu was framed and thrown into prison, where a mysterious master took him on as a disciple and taught him unparalleled skills. He became the uncrowned king of Nine Nether Prison.

The leader of the Devil Mercenary Corps, undefeated across the borderlands; the arms magnate who supplied weapons to nations around the world; the head of an assassins' guild capable of easily killing the rulers of small border countries; and the president of an international chamber of commerce richer than entire nations.

Even they could only grovel at Su Mu's feet in Nine Nether Prison!

His five-year sentence served, Su Mu walked free. Now that the caged dragon had emerged, the whole world would tremble before him.
