According to the "Book of Mountains and Seas", the four ancient sacred trees, "Fusang, Jianmu, Ruomu, and Xunmu, stand at the four extremes of the Yin Sea, standing in the Aral Sea." It is said that the sacred tree has three layers and nine branches, with mulberry leaves and elm flowers. The fruits are shaped like ten crows, with yellow snakes entwined on them. The four great divine continents in ancient times were burdened by the poisonous roots of evil. They were cursed by gods and sealed into the crystal world to become an endless purgatory. The descendants of the four divine envoys have been searching for thousands of years and finally unlocked the secrets of the crystal world and the ultimate world behind it. However, they discovered that it turned out to be a shocking conspiracy from ancient times that lasted for thousands of years. Intention: Human nature is good, with great affection and great love
