However, Mu Rufeng can still pass through the walls, but it takes some time.
Finally, Mu Rufeng spent about half a minute to successfully pass through the wall.
Half a minute, this is neither long nor short.
Thinking for a moment, Mu Rufeng immediately used [Potential Burst] and [You Die, I Live].
His strength instantly reached the Peak State.
Mu Rufeng tried again, and this time, he also channeled a large amount of soul power, and this time it was much faster, taking only five seconds to penetrate the wall and return to the room.
Five seconds, that can indeed be considered very fast.
Then, Mu Rufeng went out from the door, and this time it was even faster, taking only two seconds.
Mu Rufeng realized that, compared to the walls, the rule power of a door was relatively weaker.
Immediately, Mu Rufeng went directly to the sealed window beside him.
Soon, Mu Rufeng passed through those wooden boards and arrived outside.
