บท 129: What's Going On?

As expected, the spark was blown away and turned into flames.

"What!" Li Hehua immediately walked over to take a look. "Jiang Yue, you really made a fire piston? How are you so smart?"

"I only rolled it up as Xue Yan said," Jiang Yue said. "Yifu made the bamboo tube."

Xue Yifu also came over and smiled naively. "I didn't do anything and didn't expect it to burn up after blowing on it. Will it stop burning once it's covered?"

"Yes." Jiang Yue nodded and closed the lid again. After a while, she opened it. As expected, they could only faintly see the sparks inside. There was no flame like before. She blew again, and flames appeared again.

"This is good." Xue Yifu chuckled. "It's just a little expensive. These things are enough to buy a lot of flint stones for the family. Two pieces of flint stones can be used for a few months."

However, these few fire pistons would save a lot of their time.
