After breaking up with his girlfriend Luo Xi, Su Mo awakens a dual system. To save his younger sister, he travels through worlds to a high-martial otherworld, cutting through the martial world with heaven-defying comprehension to become the supreme "Sword Immortal," and takes the otherworld's same-named "Empress" Luo Xi as his disciple; after flattening the demonic sect for her, he shatters the void and returns to the present world. In the present world, Su Mo perfectly inherits the peak cultivation of the otherworld, transforming into the ceiling of human combat power. He secretly slays the Beast King to resolve humanity's calamity, and even plays the pig to eat the tiger in the global grand competition, face-slapping all kinds of dignitaries and petty figures with the posture of both literary and martial top scorers. To thoroughly eliminate the conspiracy of the exotic beasts, the max-level big shot Su Mo is full of ambition, ready to step into the next otherworld journey!
