Chapter 1930: The Key Question of the Optimization of the Energy Array (1)

Xu Tui looked at Ullr quietly.

Ullr also looked at Xu Tui quietly. He tried his best to look sincere to show that he was really convinced.

Ullr thought that Xu Tui was observing him and making a decision. However, in reality, Xu Tui was using his mind reading to listen to Ullr's mind.

Was Ullr convinced? No! He was still indignant. Being able to kill him three times without killing only made Ullr's fear of Xu Tui reach an unprecedented height. However, if Ullr was completely convinced and submitted to Xu Tui, he would not.

Moreover, Xu Tui knew that such a situation was basically impossible. It was basically impossible for an old coin like Ullr, who had grown up through hardships, to completely submit with two to three death threats.
