The spiritual energy revived, and Blue Star ushered in a catastrophe. The barriers to other worlds cracked, forming secret realms of other worlds. Unknown creatures often entered Blue Star and caused murders. Humanity entered panic. Some talented humans have awakened various abilities, mastered various powers such as the five elements of metal, wood, water, fire, and earth, and began to fight against the invading creatures from other worlds.
Fifth Wind, a special soldier guarding the frontier, survived an attack on an unknown creature's nest, but was forced to retire after being seriously injured. Whenever he thought of his captain, brothers and sisters who sacrificed to protect himself, Fifth Wind could only cry silently in pain. He lived in guilt for the rest of his life, wishing that he had been sacrificed. When he was dying, his soul traveled back to the early stage of the mission, and he mastered the ability to change everyone's ending, and began to change the ending of the captain, his comrades, and himself.
