Foreign Tribes Invaded, I Used a Chessboard to Suppress the Tribes

[Alien invasion] [Survival in the apocalypse] [Decisive killing] [Chessboard superpowers] [Single female protagonist] [Trust me Rhythm Online, it will get better and better as you watch it! Pure hand rubbing, no system, no stallion, strong golden fingers] The mysterious aircraft that crashed in Kunshan many years ago kicked off the catastrophe of Blue Star being invaded by aliens. The country urgently formed a secret department and named it "Nantianmen", which means the sword of the south gate to guard the country! Thirty years later, the doomsday comes. Alien warships suddenly descend on the world. Strange sickle mantises, ferocious armored sharks and other alien races sweep through the city. The once prosperous city has become a purgatory on earth! The entire nation has entered level 0 combat readiness, and the seven-day countdown to the "Spring Breeze Plan" hangs overhead. Humanity is in danger! An ordinary young man, Jiang Wei, was involved in a bank robbery, and then encountered a sudden apocalyptic catastrophe! The hostages and robbers are forced to work together to survive. Bullets cannot penetrate the body of the beast, and death follows them like a shadow! In a desperate situation, Jiang Wei accidentally activates the ancestral half-que mysterious chessboard. He uses the chessboard to kill strange beasts, obtain source crystals, condense the chess pieces, and forge divine weapons. One person holds chess and controls all directions; half a game of chess is left behind to repel all races! So what if foreign enemies are threatening? In this chess game of heaven and earth, my human race is in charge, and all the tribes who invade will suppress them!
