When he woke up, Da Zhixing found that he was no longer a human being, but had become an intelligent life form in the universe known for its wisdom and strategy-Mephilas. He has great power and an unfathomable mind, but deep down, he is still the ordinary person from Earth.
Facing his familiar yet unfamiliar hometown, he did not choose to conquer or destroy, but decided to start a "game" with the earth as the chessboard and humans and alien visitors as the pawns. He transformed into a human being and walked around the city, observing human struggles and hopes as a bystander.
When the Earth Defense Force was struggling with the mysterious monster, he left an accurate prophecy on the Internet. When the vicious cosmonaut attempts to enslave humanity, he quietly sets a trap.
He enjoys the feeling of being behind the scenes, but there are always times when the chess game gets out of control. When absolute power comes, when the fate of mankind is at stake, as a chess player, should he continue to hide, or should he go out in person and stand in front of mankind with an "inhuman" attitude? Where will this game end?
