Leng Yan has a body with the taboo of "ice and fire coming from the same source" in martial arts, and his body is naturally filled with two completely conflicting energies. This extraordinary talent is not common in the world, and the righteous see it as a source of trouble that must be eliminated, while the evil covet its terrifying destructive power and want to refine it into a weapon. Under the attack of the two parties, Leng Yan fled for his life, and finally escaped into the extremely dangerous place of Nanming Lake - the extremity area where the volcano and the thousand-year cold pool meet. At the junction of ice and fire hell, he used his body as a furnace and his life as a guide. Day after day, he endured the extreme torment of frozen blood and burning organs, struggling to find the elusive way of balance between life and death. A near-death failure almost destroyed all his meridians, but it also unexpectedly opened up a new life. With the help of strange crystals produced by volcanoes and the ancient black ice deep in the cold pool, he reshaped the meridians and discovered the true meaning of the same origin that circulates and endlessly under the surface of the conflict between ice and fire. When he steps out of the Absolute Realm with his transformed power, what awaits him is a deadly web carefully woven by good and evil... On this road, he can only use ice and fire as blades to carve his own path.
