Ji Dao Magic Sand

The half-demon sinks into the sand and takes the medical immortal Su Wan with him to control the desolate land, using chaos as his path. Immortals and demons are chasing him, and thousands of people are waiting for him. However, he uses love patterns as armor and sand bones as allies to gather all living beings to build a city. Fairy rules and magic rules? I want to overthrow the world and let all living beings coexist freely!
