Yi Qian did not question Lu Shu's decision. Since Lu Shu said that they have to watch out for Sun Xunwen, they would definitely follow his orders.
However, to Lu Shu, there were many changes in the West Region. Perhaps Sun Zhongyang was only pretending to be loving Sun Zhongyang or perhaps God Lu was about to spring a counterattack. However, all those were not important as one's life was the most important.
Moreover, Lu Shu was worried that God Lu was running around the place with six spirits of the masters. If he had really found Sun Xunwen, plotting for a counterattack was not the most worrisome but instead, the most worrisome thing was how God Lu would turn Sun Xunwen into a slave!
