Yang Tao'er finally understood. They had not informed him because Yuan Jingxing was the Chief Steward of Immortal City, and Su Zhanze was currently in a fierce battle with Ye Chen. Both Chen Yu and Xiang Zi had some status, but it was Yuan Jingxing who was in charge of the affairs of the city, which of course included the Defense System of Immortal City.
Considering the current situation, forcing Su Zhanze to fall into demonic madness was extremely difficult for Ye Chen, but if they utilized the energy of the Defense System to assist, the outcome was uncertain.
"Why didn't you tell me?" Yang Tao'er clamored.
"We didn't anticipate the situation would turn out like this," Li Mo said.
"I knew you were definitely keeping something from me." Yang Tao'er asked, "Does Qing'er know about this?" It was obviously a rhetorical question—if she was unaware of this matter, how could Qing'er possibly know?
