Ning Cheng reacted swiftly. By the time the old crone said he had deceived her, he had already understood what was going on.
He hadn't looked over the basic spiritual grass section, yet he had still scored a hundred percent. This indicated that his memory was indeed incredibly powerful, capable of remembering everything he glanced at.
Since his memory was so powerful, when the old crone had given him the Jade Slip with the Stealth Technique, he should have remembered it after just one look. However, he had told the white-haired old crone that he didn't need the Jade Slip and had even said it with conviction.
Now that the white-haired old crone had caught him red-handed, he couldn't deny it even if he wanted to.
Realizing this, Ning Cheng could only say awkwardly, "Senior, when I said I didn't need the Jade Slip, it was because I had indeed remembered the contents of the Stealth Technique it contained. I truly did deceive you, Senior, please punish me as you see fit."
