Once a destitute scholar whose family was ruined and who took refuge in a dilapidated temple, he accepted the invitation of Princess Lin Chu. Pouring out his lifelong wisdom and risking his life, he helped her rise from a nobody to become empress. Little did he know that it was all a scam; on the day of her enthronement, he was brutally betrayed, shackled in irons, and his loyal subordinates were slaughtered. His utter devotion turned into monstrous hatred, and he was reborn at the execution ground, returning to the day of the empress's enthronement. The once gentle and refined strategist completely turned dark, cold-blooded and ruthless, living only for revenge. In a mere thirty days, every step calculated, he laid a death trap, determined to make the heartless empress and all the traitors pay in blood.
