Shark Abyss

Retired Deep-Sea War King Qin Feng hides as a bodyguard—until best friend Jiang Qiao and lover An Xin betray him on a cruise. Reborn, he returns to before the giant shark attack, stockpiles supplies, and seizes the strongest watertight cabin. Mutant sharks strike again and again; the traitors pay. Qin Feng swears to protect kind Tang Tang and leads survivors out. After the ordeal his identity is exposed—and the disaster is a conglomerate bioweapon. To defend home, he must return to the deep.
