An Unjust Disaster

There is a dynasty in the world, and millions of cavalry can sweep through the war and chaos; There is a sect hidden in the mountains, and one man can cut through a thousand feet of the Milky Way with one sword; Strange beasts are seen in the depths of the forest. Ancient dragons and snakes once occupied the ruined city; Look at the gods and demons from the clouds, and control the sun and the moon with your hands holding up the sky. Later, They were all killed.
