When Xie Ai watched Li Jun entering the deep ocean first, he wasn't surprised. He even felt slightly disgusted by the scene as he continued hacking the sirens to death.
On the side, Yu Weimin nodded at him and said, "Let's all go at once. We will create an opening together."
The guy's image successfully improved in Xie Ai's heart after hearing those words.
Actually, even if they left him behind, he wouldn't really be irritated by their acts. At the very least, he genuinely wished to keep the three of them safe.
As for Li Jun…. he already had a terrible premonition in his heart about that guy. Why would he still go on thinking positively about that man? If anything, he wanted the man to prove Xie Ai wrong.
If Li Jun had offered to stay behind, his image in Xie Ai's heart would have increased a bit, but no. The man instead shed himself of all responsibilities and escaped when he found a chance.
