Wisdom Sweat Formation.
Chi Shang set up the Gu formation once more, exhausting every ounce of his strength to deduce it.
But this time, he encountered an unprecedented challenge!

Meanwhile, Fang Yuan was also pondering the matter.
"This level of difficulty has probably already surpassed the capabilities of a master, hasn't it?"
Not long ago, Fang Yuan had once again received Chi Shang's "help," allowing his Gu formation improvement plan for Silken Cave to take another great step forward, achieving breakthrough progress.

Tripling three times over did not mean increasing threefold. It meant an
