Actually, Madman had long wanted to stop doing this kind of work because he did not know how to modify the cultivation method, and he did not know how to save the lives of those Pioneers who had problems with their cultivation.
Moreover, there was a Pioneer who had problems with his cultivation recently, and this Pioneer meant a lot to all the Pioneers.
According to Madman's estimation, this Pioneer had at most half a month's time, but Madman could do nothing about it.
He had no idea how to save this Pioneer's life.
This Pioneer was the instructor of all the Pioneers. No matter what kind of cultivation method was developed, this instructor would try it first.
After the instructor tried it and confirmed that there was no problem, he would let the other Pioneers try the cultivation method.
This arrangement was also because the instructor had awakened a special ability that could allow his body to recover quickly.
