One day, the cow elder who was carrying out the alchemy prophecy was unable to detect the future of the Revolutionary Continent from the crystal ball and he saw from the ball that the Revolutionary Continent was split into scattered land pieces, and the split lands were filled with black tower-shaped objects. In order to find a way to save the world, the cow elder carefully studied the book of alchemy, which records the way to save the lost continent. "Go to the mysterious country of Buton Island in the east of the Sea of Heroes. In the mysterious country, there is a heart of the continent shining with golden light. It is said that the heart of the continent can link all things in the universe. The owner can control the change of time and space at will and has the ability to reconstruct and connect the universe. However, the energy of the Continent Heart is not infinite. With the consumption of its energy, the Continent Heart will be depleted, and if the Continent Heart of the Revolutionary Continent is exhausted, the Revolutionary Continent will also result in destruction.” After this prophecy was over, the cow elder deduced the location of the mysterious country despite that he was exhausted. The final result pointed to the bustling animal city. The cow elder wrote his prophecy on the last page of the book of alchemy and went to Buton Island alone to search for the entrance to the mysterious realm. Ever since that day, there were no news coming after. One day, the cow patriarch learned all this after he found the book of alchemy of the cow elder, and let people disclose the news that the revolutionary continent will be destroyed in the future, and solution to all of this is hidden in the mysterious country of animal city. This news created quite a stir at the time, but as time passed, people gradually forgot about it.
