I Mastered Time and Space While I Transmigrated

"Transmigrating: With the Order of Time and Space in Hand, How Can You Compete with Me?" After an “accident,” Yang Ming arrives in an unfamiliar world and awakens the power to control time and space. But to increase his strength, he has to devour other people's spirit weapons. He has no choice: he has none of his own, so he can only take them from others.

In this unfamiliar world, there are no rules to hold him back. Why shouldn't he do whatever he wants? As long as no one can kill him, he'll only grow stronger.

Only after devouring everything does he realize he's living on a chessboard. So who is the piece, and who is the player?
