When Karen, the son of a doctor from Qinglan Island, took over his father's bronze scalpel glowing with the blue light of spiritual liquid, he didn't know that this knife contained the "Seal of Life" of the ancient kingdom - and it also held the secret destiny of overthrowing the Tianlong people for centuries.
The Draco used the "forbidden water" to destroy Elda and tamper with the blank 100 years of history. His father's death was just a sacrifice for his "immortality experiment". To uncover the truth, Karen takes a knife and goes on the road: side by side with Rael, a navy orphan who has awakened his armed color, and Lina who decrypts the star map, and witnesses the transformation of the CP0 elite Viper from a killer to a redeemer.
From fighting in the foggy sea to transform Neptune, to Marie Joa destroying the conspiracy of immortality, they used scalpels as shields and spiritual liquid as blades to awaken tens of millions of civilians to resist. When the secret of the "Three Souls of the Heavenly Kings" points to the Upside Down Mountain, Karen finally understands: the so-called inheritance is the life link in the palm of the partner, and the free belief hidden in the light of the sword - can a knife that saves people cut through the righteous lies of the Tianlong people?
