Zhang Cen, a modern horse-and-blade player, traveled through time and became Emperor Chongzhen who attempted suicide. At that time, the army besieged the city, hundreds of officials fled, and the Ming Dynasty was in danger. In a desperate situation, he awakened the overlord system of riding and slashing, put aside his cowardice, armed with a mysterious iron sword, wore bright light armor, and accompanied his loyal servant Wang Chengen and elite imperial guards. He shouted "I am fighting thousands of troops" among thousands of troops. He fought with iron and blood to break through the encirclement, vowing to change his fate and revive the Ming Dynasty.
