Across the Stars, with the Best Physique

Li Lang, the king of interstellar mercenaries, was drawn into another world by the vortex of yin and yang while chatting with the AI. He took his body and became the framed useless prince of the Dai Viet Dynasty. The royal family set up a scheme to slander him and humiliate the princess, and wanted to destroy the whole family of Zhenbei Palace. Nanotechnology instantly repaired his Dantian meridians, giving him peerless combat power. He killed the imperial army on the spot, captured the prince, broke into the palace, beheaded the emperor and the prince, overthrew the dynasty with iron-blooded means, helped his father ascend the throne, ruled the world from then on, and began to sweep the world.
