“Where is this mysterious place?”
Looking at him with serious expression, Feng Lingxi looked curious, and Dugucheng pulled her, “I will know if I go with me.”
Feng Lingxi was pulled by him to the mountain not far from the front of the valley, and stopped in front of a cave.
“It’s here.”
Feng Lingxi looked at the cave in confusion and saw many white stones at the entrance of the cave, and there were not many weeds around Shandong.
“The stones here are a bit strange. It is said that the stones will condense into ice when they sink into the water. Xi’er is smart, do you know what this is?”
“Condensate into ice?”
Feng Lingxi’s eyes lit up. Could it be that the cave is saltpeter?
Dugucheng nodded, “I also heard from the soldiers in the camp that I accidentally discovered this cave while patrolling. Seeing the difference between the stones in the cave and the outside, I picked up a few pieces and wanted to take them back for research. I wanted to wash them and take them out, but I didn’t expect the stone to turn them into ice in the water.”
After hearing this, Feng Lingxi hurriedly walked into the cave, looked at the stones in the cave, squatted down, picked up one, put them on the tip of her nose and sniffed it, with an incredible look on her face. This is really saltpeter. saltpeter can condense into ice and can also be used as gunpowder.
“Did Xi’er see that, what’s wrong with this stone?”
“This stone should be saltpeter. Master once said that this stone can be used as medicine or made into gunpowder, which is extremely powerful.”
“Gunpowder?”
Dugucheng was curious when he heard this word, “What is the gunpowder that Xi’er talked about? Can it also cure diseases?”
“Of course not. This gunpowder is very powerful. It can fight a hundred and make such a big gunpowder, and it can collapse here.” Feng Lingxi gestured, looking at Dugucheng’s shocked eyes. It was normal for them to not understand the Great Yuan Dynasty.
And she was also considering whether to make these saltpeters into gunpowder to help him.
“Does Xier know how to make gunpowder?”
Feng Lingxi nodded, “Master told me, but I have never tried it. After all, I have never seen this saltpeter before.”
“Will Xier try to make gunpowder?”
Feng Lingxi looked at the expectation in his eyes and said lightly, “If you want, I will try it, but it may not be successful.”
“Then try it, what you need, just say it to me, I will get it for you.”
Feng Lingxi picked up a piece of saltpeter and said, “Let’s go.”
For some reason, Dugu Cheng brought her here. She always felt that he was testing her. She wanted to know from her why she had so many. He didn’t say anything. This way of doing it was, Feng Lingxi felt a little strange.
Along the way, Feng Lingxi was silent and said nothing. Dugucheng wanted to speak but stopped several times.
Back at the room, Feng Lingxi took the saltpeter
and started to study it. Dugu Cheng told her that he had something to do and went out.
“Xiaoli, come.”
