Before the chessboard, indeed, two Immortals were watching the trials of Su Chengyu with smiles in their eyes. Eventually, it was Kunwu who spoke first.
"Young friend, you are astute, but how did you detect that I was watching?"
Listening to the unsurprising answer that arose in the void, Su Chengyu spoke indifferently,
"Because you were not only watching, but you also directly intervened in the content of the trial, did you not?"
"What makes you say that?"
Su Chengyu calmly responded, "The trial on the sixth level, while seemingly still consisting of nine challenges, was of a completely different magnitude compared to the previous levels. I do not believe that everyone who comes to Ascending Heaven Tower would undergo trials of this caliber."
There was another point that Su Chengyu did not mention: Ji Yuzhu had also come to Ascending Heaven Tower.
