Xu Ping'an had been immersed in contemplation.
He continuously tried to compress the particles in the space around him, increasing the density of the particles in the surrounding space.
After repeated attempts, he finally succeeded in compressing the surrounding air particles after three days of effort.
As he compressed the air particles around him, Xu Ping'an discovered that increasing the particle density in a given space would affect a person's movement speed.
In this way, Xu Ping'an's domain, although it couldn't oppress people to the point of immobility like Situ Lie's, could still exert a certain influence.
Previously, his domain only enhanced his own attacks and did not affect others.
Now, he had gained an additional method.
However, this was not what he wanted. What he sought was to master the great forces of heaven and earth, particularly in terms of time and space, especially time.
