章 376: Extra Scoops

Xue Sifu didn't know that. He was busy weighing the saltpeter and putting it aside.

As for Xue Yifu, he took a big pot and a small pot. He used the same method as before, putting the small pot into the large pot. The large pot was 80% filled with river water, while the small pot was filled with well water, but the water level was lower than the large pot.

Seeing that Xue Yifu was done, Xue Sifu immediately poured the saltpeter into the large pot.

The saltpeter began to melt quickly in the water again, but it did not freeze at a speed visible to the naked eye like just now. Moreover, it was almost completely melted, but there was no sign of freezing.

Jiang Yue signaled Xue Yan to speak.

"Sifu, it's probably because there's not enough saltpeter. Let's try and add more saltpeter." Xue Yan said hurriedly.
