With a single palm strike, Su Mo sent waves three hundred feet high surging across the Soul Sea, yet instead of joy, his face was filled with gravity.
Though he had not used his full strength in that strike, he had still used seventy or eighty percent of it. Yet it had merely shaken the Soul Sea.
That was with Feng Xueji and Wu Kong attacking from two other directions as well. This showed just how powerful this formation was.
Moreover, Su Mo discovered that the instant his palm strike hit the formation and it endured the violent attack, the incomparably dense soul power within the Soul Sea swiftly poured into the formation to reinforce it.
In other words, the stronger the opponent, the stronger the formation became.
The stronger the attack it received, the more soul power it absorbed from the Soul Sea, and the sturdier the formation became.
This showed that with the current strength of the three of them, it was almost impossible to break the formation in a short time.
They could only slowly wear it down through prolonged consumption.
Only after the soul power within the Soul Sea had been nearly exhausted would they have a chance to shatter the formation.
But no one knew how much soul power the Soul Sea actually contained.
There was no way to predict how long it would take to wear down the soul power within the Soul Sea.
Boom! Boom! Boom!
Next, Su Mo attacked continuously, palm strike after palm strike raining down upon the formation without end.
Every strike contained the power of eighteen small worlds, enough to shake heaven and make ghosts weep.
As his palm force fell again and again, heaven crumbled and earth split.
The terrifying power of the worlds possessed immense destructive force.
