Death Cultivator 2

Fight for your Soul. 

Death cultivator Grady Hake thought his problems would disappear when he and his friends became members of the strongest gang on the prison planet, but all it did was thrust them into the kill-or-be-killed world of the Eight-Legged Dragons.

As Hake fights his way through the Dragons' grueling trials, he soon discovers there's a deadlier force on the prison planet than a death cultivator, even deadlier than the Angel of Death, and it wants his soul. Learning to cloak his lethal Spirit attacks in oblivion might help Hake rise through the ranks of the Eight-Legged Dragons, but it won't keep him and his friends alive…or his soul in one piece.
