Troubled times are like a melting pot, and human lives are like grass. He was once the undefeated king of the underground arena, crushing all challengers with a pair of iron fists. When the princes were divided and the world collapsed, he was forced to be involved in the quagmire of power - rely on the heroes or establish himself as king? Every choice you make is a matter of life and death. Powerful as a sword, betrayal as a shadow, he rose from the humblest of warriors, fought tigers with his bare hands, and destroyed cities with laughter. On the day when the iron hoof trampled the mountains and rivers, he returned with the name of being invincible, and wanted to redefine the "throne" with his own hands on this chessboard paved with bones.
