Lu Changhe wanted to collect qi, but it was absolutely impossible for Wei Yuan to agree to this. Not to mention that it involves so many people's paths, which goes against the fundamental beliefs of Wei Yuan, and no one knows if he will secretly do something. If it harms the root of Qingming, Wei Yuan would deeply regret it.
As for whether Lu Changhe is happy or not, Wei Yuan really can't care that much. Ever since Wei Yuan forced the Crown Prince to commit suicide, the enmity between them has become quite significant.
But Wei Yuan was also a bit puzzled. It was just some natural spiritual energy; why would it make Lu Changhe lower his stance and send people to negotiate with Qingming?
So Wei Yuan went to find Bao Yun and asked carefully, only then did he learn that in family clans, qi collection and bone replacement are quite common.
