The ordinary forces that came to participate in the competition soon sent all their people in. However, for the four most powerful divine worlds, they were not in a hurry to send the contestants in.
Because only they knew that every time the world battle ring began, a king would appear in the inner space. This king had wisdom that was no less than that of human beings.
Although the king would not attack at will, he would hide in an unknown place to control other powerful beasts to hurt the people participating in the competition.
Because of this, every time the battle ring began, the king of the beasts would send a large number of beasts to ambush at the entrance of the passage.
Once they met the contestants, these beasts would use all their strength to attack.
After a while, there were only the people of the four biggest divine worlds left outside the world battle ring.
