So It Cannot Be Solved

Wisdom sweat formation.

Chi Shang set up this Gu formation again, doing his utmost to deduce the formation.

But this time, he met with an unforeseen challenge!

Difficult, it was really difficult, even the first two rounds added together and multiplied by ten could not match this.

Chi Shang felt like he was a baby trying to ascend a tall mountain.

"This difficulty… no wonder Wu Yi Hai is so confident!"

"It is related to the contents of the first two Gu formations."

"No, I must use this chance to humiliate Wu Yi Hai. I will make him admit that he is inferior to me in front of Fairy Si Liu!"

After a day and a night, Chi Shang's eyes were filled with blood vessels, he was doing his best to try and tackle this problem.

At the same time, Fang Yuan was thinking.

"This difficulty, it has likely surpassed the limits of grandmaster attainment level?"
