Gu Yu knew what Cheng Xi meant. According to the plan, they wanted to use Devon's energy to extend Lily's life. Cheng Xi was afraid that they would kill Devon.
In Cheng Xi's opinion, it was fine if she died, as long as Lily could be saved. However, Devon was the key to saving Lily now. Nothing must happen to him.
Gu Yu also began to hesitate. On one hand, he was worried about Lily, and on the other hand, he was worried about Cheng Xi. Although Devon said that he loved Cheng Xi, he was afraid that he would not care about anything at the moment of life and death. If he attacked, he might also kill her.
Yunbao didn't dare to move when she saw that Fourth Uncle didn't attack, but she stared fiercely at Devon to express her dissatisfaction, as if that cute face could scare him.
Devon thought that his words had frightened them. He smiled and said, "As long as you let us go, I naturally won't touch her. Otherwise, we will die here together."
