A righteous gamble, wagered in the name of loyalty, cost him his entire youth.
A special "university" awarded degrees in darkness.
After a carefully planned return, the roles of hunter and prey had been reversed.
Lin Feng was an ordinary college student. In an attempt to save his closest friend, Chen Hao, one moment of poor judgment led him to shoulder an enormous crime and land behind bars. Naively believing his brother's promises, he waited to see daylight again. All he got in return were cold handcuffs and utter betrayal.
In the hellish prison, he met the mysterious Mr. Mo. This enigmatic "mentor" pulled him up from the depths of despair, only to lead him into another, even darker world. Loopholes in the law, psychological manipulation, combat and killing, financial schemes... What Mr. Mo taught him with everything he had was not the path to redemption, but a weapon of revenge. This "Abyss University" used cruelty as its textbook and survival as its credits, completely remaking Lin Feng's soul.
Years later, Lin Feng returned. He was no longer the naive, timid boy he had once been, but a calm, meticulous machine, harboring a dangerous power. His former friend Chen Hao had used lies and his family background to climb over Lin Feng's corpse and become a winner in life, envied by everyone: polished and seemingly flawless.
