章 106: This Is How A Man Should Be (1)

Previously, Lin Feng had used the astral winds to temper his mental strength in the boundary realm. Unfortunately, before he could reach the level of qualitative change, he left because of Tarzan.

Now, he was only one step away from achieving qualitative change in his mental strength, so he began to consult the black cat.

When the black cat heard this, it explained to him, "The qualitative change of mental strength is actually like the process of a piece of iron turning into a sword. It needs to be tempered thousands of times."

"If you want to temper your mental strength, you need pressure from the outside world to compress your mental strength."

The black cat turned around in Su Xiuxiu's arms and changed to a more comfortable position. It continued, "And the external pressure can't be too great. Otherwise, it might instantly obliterate your mental strength. However, it also can't be too small. Otherwise, it won't achieve the effect of tempering.
