The soul of the strongest dragon god gave all its power to the dragon stone of the game, and the soul flew back into the sealed chamber. Therefore, in the game, they are going to find the "Lock of Seal" and "Key of Seal", unlock the seal of the strongest Dragon God in the Dragon Clan, and fight with him against the "Wave of Light".
