One day, spatial portals suddenly appeared all over the world. Strange animals no one had ever seen before poured through them and began attacking humanity. Then a young man from Gansu recognized them as monsters described in the Classic of Mountains and Seas. He found a way to inform the government, and everyone learned where the creatures came from. China was the first to organize a counterattack, while countries around the world began preparing their own responses. Unlike the chaos in Western nations, China organized its troops and fought back decisively. Before long, its counterattack achieved excellent results. The young man then proposed that the monsters’ corpses could be eaten and offered many benefits. Later, when China began pushing through the portals, it discovered that the world on the other side was the very land described in the Classic of Mountains and Seas: the Shan Hai Realm. China then organized nationwide cultivation while continuing its advance into the Shan Hai Realm, fighting all the monsters there. Gradually, it uncovered the realm’s secrets: the ruins and mysteries left behind by the ancestors of the Chinese people, as well as cultivation methods for humanity. These methods were then gradually shared with all the people of China. Later, they also discovered an ancestral temple of humanity, containing statues of Nüwa and the Three Pure Ones, statues of the Three Sovereigns and Five Emperors, and the highest cultivation arts of humanity. They also learned the secret of the Shan Hai Realm: it was the passage linking our world to the primordial world. Through the Shan Hai Realm, one could reach the primordial world.
