The Exclusive Saint in the Opening Contract

In 2076, the Blue Star Utopia collapsed, alien races invaded, and purgatory descended. One second before the start of Orphan Lin Chen's rebirth in the apocalypse, he awakens to the whole-life mutual hostility system! The poisonous tongue system raises eyebrows every day, has a variety of prank props, and selects outrageous tasks. After returning from rebirth, the first thing he did was to bind a life-and-death contract to his beloved Su Qingyue! Protect the gentle heroine, protect the kind adoptive parents, and protect the sisters with special physiques. Form the strongest team of seven people and fight from ants in the ruins to become the master of the Blue Star in the apocalypse! The funny quarrels make me laugh every day, and the separation and death make me burst into tears!
