Lin Jin, a genius in the 25th century, died tragically at gunpoint because his publication of the "Abyss Algorithm" touched the interests of the powerful. However, he unexpectedly created a quantum resonance with the dying eight-year-old prince Zhao Heng of the Qi Dynasty, forming "one body and two souls", and they went to the troubled times together.
Yong'an City was destroyed, Shuo Mo's iron hoofs trampled the Qi Chao River and Mountains, and Zhao Heng (Lin Jin) took the remaining troops on the road to escape. The plague was raging at sea, and they used herbal medicine and wisdom to build a lifeline of defense; Shuomo Navy encircled and suppressed, using fire attacks, mines and terrain to fight back; the Yongwang of the clan concealed ulterior motives and colluded with foreign enemies, and they played a strategic chess game step by step.
Lin Jin guided Zhao Heng with cross-generational knowledge: making fresh water, making firearms, issuing bonds, building an epidemic prevention system, turning "trade fire" into "wolf smoke", and breaking the economic situation; Zhao Heng lost his immaturity in the flames of war and betrayal, and grew from a child who relied on his "brother" to a monarch who can rule the world and protect his people.
From the life-and-death game in the sea where ghosts see sorrow, to the bloody guarding of Guangzhou City, to the ultimate sacrifice of "Sparks Burning the Sea", the two souls achieve each other's achievements in symbiosis. Lin Jin burned out his consciousness in exchange for a glimmer of life. Zhao Heng carried his legacy, used peach blossoms as an oath and the people's hearts as a seal, rebuilt the Qi Dynasty on the ruins, let the sparks of the other world turn into the sky, and continued to write the new legend of the Great Qi.
