Hundred poison immunity

After Bai Yun was done with muscle tempering, it had already reached midnight. He was now covered in impurities that had been pushed out by the tempering process. But the muscles only held a little bit of impurities, and thus there was only a very thin amount of impurities on Bai Yun's body.

Bai Yun thought for a while whether he should start on the next process of refining the various materials he had gotten, or hundred poison immunity. But Bai Yun realized that he did not have enough time left for it.

So Bai Yun spend a little bit of time organizing his various gains. The first thing he took out was the three headed snake. Bai Yun skillfully disassembled it and separated its various parts. Bai Yun briefly considered using the bones of the snake for the bow but a closer look revealed that it would be too flexible.
