Even after further study, Bai Xiaochun was left with no other option than to give up on the idea of combining soul medicine with ordinary medicinal pills. Although he was a bit disappointed, there was simply no way to get these two completely different types of medicine to work together.
"Oh well. At least I know how to add toxic elements. Perhaps that will prove to be useful one of these days." With that, he continued on with the task of concocting soul medicine.
After all, he had promised the Blackmountain Tribe that he would do this for them, and he was the type of person who lived up to his promises. Therefore, the following days were focused mostly on that task.
All of the work was done with the souls they provided. Considering the predicament they were in, and how soft-hearted Bai Xiaochun was, he didn't impose any further requirements on them.
