Su Mo's face was not filled with joy, but with solemness.
Although he didn't use his full strength in the palm just now, he had used 70 - 80% of his strength. It only shook his soul sea.
And this was with Feng Xueji and Wu Kong attacking from the other two directions. From this, one could see how powerful this formation was.
Moreover, su mo found that when his palm hit the formation, the moment the formation was under the fierce attack, the rich soul power in his soul sea quickly added to the formation.
In other words, the power of this formation would become stronger when it encountered a stronger opponent.
The stronger the attack, the more soul power it absorbed from the soul sea, and the stronger the formation.
From this, it could be seen that it was almost impossible for the three of them to break the formation in a short time with their current strength.
The only way was to slowly wear it down over a long period of time.
