Guardian's Prophecy

They are a special group of people who guard the ancient Eastern civilization. Their existence is like a mystery, and people can't find it. They never show their true colors to others, what we see is always an illusion. But all this changed because of his appearance. The prophecies from ancient times have gradually appeared. The elemental power between heaven and earth has begun to be chaotic. The ancient civilization has gradually been forgotten. They have begun the "awakening" plan, all just to protect the former glory and the civilization that belongs to them. He is a guardian, but unlike other guardians, he is the last trump card of the guardians. He is the son of prophecy. In ancient times, guardians with the same ability as him were called "controllers"...
