However, instead of finding peace in death, he miraculously awakens in his fourteen-year-old body. Armed with decades of combat experience, unyielding determination, and the horrific memories of his past life, Jack vows to rewrite history. He will dismantle his wicked family from the inside, shield his sister from her tragic fate, and destroy anyone foolish enough to stand in his way. This time, the youngest son of the Marquis house is truly invincible.

Betrayed by his family and transformed into a bloodthirsty monster for revenge, Jack dies full of regret. Mysteriously sent back in time to his childhood, he uses his future knowledge to protect his sister and dominate his enemies.
