"I got it."
A King who was proficient in Buddhism seemed to have thought of something and said slowly with a grim expression, "I once saw a record of Great Emperor Infinite in an ancient book."
"In the records, Great Emperor Infinite released a secret skill during a huge battle and avoided almost all the enemies' attacks!"
"That secret skill is called No Self."
No Self!
The moment those words were said, it caused a commotion in the Blessed Heaven World Square.
Another King looked at the figure hidden in the void on the battlefield and said in a deep voice, "That secret skill has already come into contact with the profundity of emptiness. That's the reason why this lad can hide in the void and avoid the attacks of the 18 peerless divine powers!"
The word for emptiness corresponded to both the void and also space.
The formation of a Grotto-heaven was to create a spatial chamber.
