Obviously, Xu Que wouldn't let Shang Wu go!
If it weren't for Situ Hai Tang and Shang Ling, Xu Que would have already killed him back in the Snow City.
When Xu Que knew that Shang Wu had invited help from the Gong Family, he had made up his mind to kill Shang Wu.
Xu Que had killed the four old men of the Gong Family in front of everyone, but he had let Shang Wu go. He did so simply because he did not want to be reprimanded by Situ Hai Tang.
Secretly, Xu Que had ordered his thunder illusion body to hunt for Shang Wu.
That night, Xu Que gathered together with all the guards and Generals and had a small meeting.
Xu Que warned them that no one should tell anyone else that he had killed the people of the Gong Family, since if anyone knew about this, the entire Water Nation would be dragged into a war.
Hearing this, everyone nodded and swore that they would keep it secret.
