Bai Yue had become Zhou Shu's eldest disciple. He walked in the forest while cultivating.
His face was pale, and beads of sweat kept dripping from his forehead.
This was extremely abnormal.
Although Bai Yue didn't know the Martial Dao previously, his strength was comparable to a Grotto-Heaven realm expert, and his body was so strong that ordinary Grotto-Heaven realm martial artists couldn't compare to him at all.
Not to mention that Bai Yue had lived for more than a hundred years, and his willpower wasn't something ordinary martial artists' could compare to.
For him to have such a reaction, it showed how much pain he was enduring.
The power of the Iron Smelting Hands Technique was not top-notch, but the difficulty of cultivating it was almost incomparable.
Bai Yue had become Zhou Shu's disciple to learn the art of forging. Zhou Shu didn't teach him any other techniques but the Iron Smelting Hands Technique.
