The mind would be in a state of disorder when one was concerned!
Ji Tingyu had guessed Jiang Yi's thoughts accurately, and she was clear that Jiang Yi was a very intelligent person. He was very terrifying when he was calm, and it would be hard to find any loopholes on him.
Since that was the case, she had to make him anxious. A fake Su Ruoxue was enough to make him lose his cool. As long as he was no longer calm, he would no longer be invulnerable. As long as they could catch one loophole, it would be enough to consign him to eternal damnation.
Take this moment for instance: some trick had been done to this fake Su Ruoxue by Ji Tingyu, and her soul spirit was deep asleep. Jiang Yi wasn't thinking that this Su Ruoxue was a fake but had been poisoned. He would assume that Wu Ni had made use of some antidote for the poison to impede him.
