Global Defense Breach! the Little Cub Holds a Copy of Othello

Three years ago, an alien game called Reversi landed on Blue Star, and the country's borders were turned into chess chips. Humans around the world were randomly selected by the system to become chess players. Rules: If a player loses the game in the ghost dungeon, the entire administrative district corresponding to the real world will be wiped out, and all mountains, rivers, cities, and creatures will be reduced to nothingness. In three years, nearly 60% of the world's landmass has been eroded by chessboard rules. Territories of many countries have been eliminated one after another. The survivors are trapped in a small land. Materials are scarce and people are panicked. Despair has swept all mankind. Mental breakdowns and suicides have increased year by year. Misfortune never comes singly. When players were selected for a new round of games, a rare flaw occurred in the system program, and a small human cub was forcibly pulled into a terrifying chess game filled with murderous intent. The child is small, docile and sensible, and is courteous to others. In a dungeon world full of bloodthirsty monsters and vicious calculations, from the perspective of conventional survival logic, the outcome is destined to be death. After learning the news, all mankind fell into complete collapse, and human civilization, which was already on the verge of extinction, was cast into a haze of extinction.
