After foreseeing an impending attack on the North Shore Wharf by an S-rank alien beast, he asks his younger sister, Lin Xiaoya, to carry him to the Supernatural Bureau and turn him in. At first, nobody believes Xiaoya, until Lin Musen displays his astonishing abilities and hacks into the central bureau's system to issue a crisis warning, shocking everyone. To protect the Dragon Kingdom and shelter his only younger sister, Lin Musen chooses to cooperate with the Supernatural Bureau. He then begins evolving continuously by harnessing high-voltage electricity and feeding on alien beast nutrients. He cultivates supernatural fruits to build an elite team of dual-ability warriors. When a hundred-billion-strong SSS-rank beast tide arrives ahead of schedule, the guardian divine tree sweeps across the globe, defeating alien beasts and turning humanity's desperate situation around.
