Thinking this over, Gu Shanhai hesitated, what if he himself got into trouble...
Oh, no, the opponent was still not cautious enough because someone truly cautious wouldn't actively seek trouble.
So, his purity wasn't high enough, and when his purity was deficient, it meant he wasn't cautious enough, and there was no need to worry about the other party unexpectedly turning the tables.
For this reason, he performed a divination to inquire about the strength, and the result of such a question docked him three thousand years of life, which was the price of a king of myriad herbs.
The outcome naturally was the same as with other Martial Arts True Immortals; all their strengths were suppressed and they couldn't make a move at will.
This reassured Gu Shanhai. If the opponent were truly hiding their strength, then Gu Shanhai's actions would have been much more ruthless, directly annihilating Heavenly City!
