He was once the most dazzling general of the Great Xia Dynasty, the patron saint of the north, and was known as the "Invincible Wolf". With an edict and a conspiracy, he fell from the clouds and became a criminal guarding the abandoned fortress "Ghost Valley". When the war broke out again in the north, the barbarians trampled the mountains and rivers with iron hooves, and the princes in the court were helpless, the forgotten man, with three hundred old, weak, sick and disabled, re-entered the chess game of blood and fire. This time, he not only wanted to protect the thousands of miles of rivers and mountains behind him, but also used the bones of his enemies and the blood of powerful officials to wash away all the stigma that had been spilled on him. The country and the mountains are the board, and all living beings are the sons. What he wants to play is a big chess game that will overturn the world.
