“Jang Jinmyeong”, a martial arts master who mastered the forbidden technique “Gyuhwa Bojeon”, reached the peak of power—only to be branded a traitor and thrown off a cliff.

Just before his death, he realizes two grave mistakes:

1. He gained immense power through Gyuhwa Bojeon at the cost of losing his manhood.
2. He failed to eliminate the vile traitors Wang Jin and Seop Pyeong when he had the chance.

But instead of dying, Jinmyeong awakens in a mysterious realm, where he encounters the original copy of Gyuhwa Bojeon , and is sent 32 years back in time—right before he lost his manhood.

Now, with his body intact and the power of Gyuhwa Bojeon still coursing through him, Jinmyeong embarks on a new path.

This time, he will correct the regrets of his past life… and seek vengeance against Wang Jin and Seop Pyeong, the men who betrayed him.
