The first step was always the hardest. After succeeding once, succeeding again became much easier.
Another four days passed. After failing seven times, Yang Zhengshan once again refined a furnace of Jade Marrow Pills, and this time he produced fourteen pills.
After that, Yang Zhengshan continued refining Jade Marrow Pills. Gradually, his success rate stabilized at around twenty percent: out of ten attempts, he could succeed with two furnaces, each producing about fifteen pills.
This result looked very good, but in reality, it was a money-losing business through and through.
One must know that each time Yang Zhengshan refined Jade Marrow Pills, he had to consume two hundred Spirit Stones. Five attempts meant one thousand Spirit Stones, yet the result was only fifteen pills. On average, each Jade Marrow Pill cost sixty-six Spirit Stones.
This cost was no ordinary level of high. It was even higher than the selling price of the Qi Nourishing Pills from the Lingxiu Three Sects.
The price of a Qi Nourishing Pill was fifty Spirit Stones each, and that was their selling price. Their cost price was probably only around twenty Spirit Stones.
Although the Jade Marrow Pills refined by Yang Zhengshan should be somewhat better than the Qi Nourishing Pills of the Lingxiu Three Sects, the cost difference was far too great. If he took them out to sell, they would probably find it very hard to compete with the Lingxiu Three Sects' Qi Nourishing Pills.
But then again, Yang Zhengshan could not buy a large number of Qi Nourishing Pills. If he wanted to satisfy his own cultivation needs, he could only refine Jade Marrow Pills.
Moreover, as the number of times he refined them increased, his pill-forming rate would also grow higher and higher, so his current losses were still very necessary.
