There's only nine minutes left.

The end of the world is coming!

The story revolves around the rebirth of Lin Yuan, a once-humble student who, after his world is upended by a cosmic event, enters a world beyond his wildest imagines-one that is no longer confined to classrooms and textbooks, but filled with blood and despair.

As Comet 6 passed overhead, a mysterious cloud of dust triggered the Earth's transformation. Monsters are about to invade the real world, and unprepared humans can only serve as food and playthings at the feet of various magical creatures.

But when he experiences a rebirth, the information he once remembered brings him new opportunities, and he finds himself standing on the precipice between the old world he knew and the new world that awaits him. He knows from his pre-rebirth memory that the first people to invade the modern world through random location portals are Goblins, and he still has a chance to survive!

Compared to his previous life, nine minutes was enough time for him to be well prepared. Amid the chaos, Lin Yuan's laughter reflected his defiance and acceptance of the new reality. His journey is no longer about passing exams or young romances, but about survival, identity and power in a world under siege.

Lin Yuan's transformation is not only reflected physically, but also mentally and spiritually.

The new world is only a wild, only strength is the root of everything!

He wants to change his destiny and walk a different path of legend.

As he struggles with his extraordinary rebirth, will he be able to redefine his life and destiny?
