Xinmen Wei family and Wei hai pang family were both well-known families in the Qing-Yun realm. They were famous for growing spirit herbs and making spirit pills. The spirit herbs they grew were of higher quality than the other families. However, they were only for their own use and never sold to the public.
It was only until this generation, when the talents of the descendants of the two families had withered, and there were no outstanding spirit alchemists, that the idea of selling the spirit herbs to the outside world came into being.
