When Ren Xiaosu left, made it crystal clear to Yan Liuyuan that if Big Sister Xiaoyu was still taking care of him at that time, he would have to bring her along with him as well. If Xiaoyu had already taken the money and left, then Yan Liuyuan should go there and hide by himself.
Don't hope to get lucky, and leave immediately at the sign of any trouble!
In Ren Xiaosu's opinion, nothing was more important in this world than staying alive. It was better to have a gun for self-defense than having nothing at all.
Ren Xiaosu also wished that he could bring the gun with him into the Jing Mountains. But compared to his own safety, he felt that it was better to leave the gun for Yan Liuyuan.
It was just that Yan Liuyuan and Ren Xiaosu could not have expected something would happen so soon after Yan Liuyuan had retrieved the gun.
