In a distant alien world, there is a towering giant tree. There are no leaves or flowers on the tree, only fruits. The fruits are large and hollow. At the top of the tree, there is a fruit that gathers the aura of heaven and earth and the essence of the universe. It gave birth to two Tianyuan gods: Star and Sapphire. The belly of this fruit is its residence, later called Tianyuan Palace. There are mountains and rivers in the fruit, but there are no intelligent creatures like the Tianyuan gods. Because of loneliness, Tian Yuan Shen connected the other four empty giant fruits, and used his own magic to eliminate the obscurity in them, creating an environment similar to Tian Yuan Palace, hoping to breed new life. Four and a half billion years later, the advanced life expected by Tian Yuan Shen appeared, but another problem began to bother them again: the home of the souls of the dead, so they created another fruit as Hades, which they were in charge of. However, a new problem appeared again. Higher beings began to be divided into races, and they hated each other, plundered, and were in chaos. Therefore, Tian Yuan Shen came forward to purge the four realms, select the best, divide the territories, control the opening and closing of the passages with the power of the emperor, and create equal strength to restrain the four realms. However, the chaos did not end there. The melee in the four realms caused Tian Yuan Shen a headache. Finally, Tian Yuan Shen came out again to stop the four realms. The melee in the four realms was stopped, and the passage was narrowed and opened regularly. The grievances of the four realms were put to rest. With Emperor Ling's departure, the tense atmosphere finally began to ease, and the barriers between the four realms were slowly weakened. At this point, the economic technology of the four realms began to grow rapidly in line with Tian Yuan Shen's expectations. However, when Tian Yuan Shen gradually relaxed his vigilance and allowed the development of the four realms, an uneasy atmosphere gradually emerged...
