Mountain and Sea Demon Lord

There are great monsters in the mountains and seas, and their movements are elusive. They may sink to the bottom of the sea, hang in the sky, hide in the mountains and rivers, or hide in the swamps. The only one with extreme power is a great demon. When the big demon gets angry, the situation changes; when the demon shakes, the mountains collapse and the earth breaks apart! Therefore, the waves of the sea are thousands of miles away, the clouds in the sky are rolling, the mountains and rivers are shaking unsteadily, the swamps are flooding thousands of miles, and there are panic and natural disasters, most of which are caused by demons. It's extremely strange, and it's also a big monster. In ancient times, there were great demons fighting each other, and blood spilled on the earth. The red blood lasted for thousands of years. If the human warriors went there, they could enter the secret realm. In the secret realm, it is very magical. The sun, moon, mountains and rivers appear one by one, there are countless exotic flowers and plants, and there are even birds and animals living in it, playing in the flowers, swimming in the clear streams, or soaring in the sky. It is a paradise. The beasts in the secret realm cannot leave the secret realm independently, but a strange person establishes a connection with the strange beast and takes it out of the secret realm. Strange beasts have spirits, later called demon spirits. The demon spirits are strange, they can appear as beasts, fight with their scales and claws, and are no less powerful than ferocious beasts; they can also turn into patterns and be tattooed on their bodies, giving humans extraordinary powers! After thousands of years, the human race tamed demon spirits, became demon masters, and fought against mountains and seas! ———————————————— When you don't know how to write an introduction, the prologue is the introduction. ——Qing Shengyu
