Battle of Alien Beasts

Many years ago! The world was swallowed by darkness. There was a giant named Pangu who created the world! There are many strange beasts or elves in the world! Later, in order to survive, human beings used some methods to drive for their own use, which is similar to the summoning in the Yu-Gi-Oh! Egypt chapter. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
