Chapter 6699: Chapter 6699: mutation

The other three refiners also arrived one after another. Yun Chujiu learned from their conversation that the refiner in front of her was surnamed Wu, and others addressed him as Master Wu.

One of his two disciples was called Zhu Kang, and the other was called Ma Cong.

For the whole day, Master Wu didn’t show any abnormalities. He only instructed Yun chujiu to keep a close watch on the fire before he left. He couldn’t rest for one night, so that the sword would be ready the next day.

This was also the difficulty of the fire-making task. Sometimes, it would take two or three consecutive days and nights.

Fortunately, there was no class the next day, so Hei Xinjiu was not worried.

During the day, she watched Zhu Kang and Ma Cong forge ores. The process was similar to what she had mastered before. It was just that she did not know if there would be a process of pouring sword qi into the furnace before it was ready.
