Hearing Yun Niang's words, Han Shu's eyes flashed, thinking of what had happened before, and his heart began to be curious about what Yun Niang wanted! But then he shook his head again, could these three ordinary things really break through the boulder?

In order not to disappoint Yun Niang, Han Shuyan immediately sent someone out to find saltpeter, sulfur and sawdust to come back!

Sulfur and sawdust were two things, and the soldiers of Han Yue quickly found them, because sulfur is really not a rare thing on the border, and it is produced in extremely hot places on the border, so sulfur and sawdust are easy to find.

But the saltpeter that Yun Niang said gave the soldiers a big headache, and they could only be cheeky to find Yun Niang and ask.

"Childe, my subordinates are not very clear about the saltpeter in Childe's mouth, please ask Childe to solve your doubts!"

Yun Niang's eyebrows are lightly raised, isn't it? She had read so many books before, and they had more or less mentioned the ingredients for making explosives, because they were simple and easy to remember, and the ingredients were all things that could be obtained anywhere, so she wrote them down! Who knew that people now didn't know saltpeter, which suddenly made Yun Niang feel a little headache!

In the twenty-first world, the thing in the explosives was indeed called saltpeter! But maybe not in this place!

Yun Niang frowned in contemplation, and quickly thought about what was written in the original book in her mind! In the end, he tentatively asked Han Shuyan beside him.

"Do you know that a white stone is produced in the mountains? Or powder! By the way, you can go to the pharmacy and ask, it seems that this thing can be used in medicine, maybe you can buy it in the pharmacy! ”

Speaking of this, Yun Niang's voice stopped abruptly, where to find a pharmacy in this place now? This idea is a bit unrealistic, after all, it will take more than ten days to go back and forth from here to the nearest border city of the Yuan Kingdom, and I suddenly stood up a little irritated!

"Childe, is that white stone you said frost? The subordinates seem to have seen it in the place where they were digging sulfur, but it seems to be transparent, but I don't know if it is the saltpeter that Childe said. ”

When Yun Niang heard the soldier's words, her face was happy, and she stepped forward to grab the soldier's sleeve? Surely saltpeter is a white and transparent stone, either produced in a dry and hot place or a mineral spring, on the wall of the cave, the border is extremely hot in summer, since there can be sulfur, then there must also be saltpeter, and suddenly the head nodded hard.

"Yes, yes, that's it! Pick some for me! ”

The soldier looked at Yun Niang and said that what he said might be what Gongzi wanted, his face showed embarrassment at the moment, and he looked at the boss nodding at him, and turned around to say goodbye immediately.

When the soldiers mined the saltpeter back, it was already the second day, Yun Niang immediately asked everyone not to disturb her, and ran to the tent to work alone.

Yun Niang took all the things and went directly into the space, she was afraid that she would ruin the whole place if she was not careful!

The saltpeter brought back was indeed a transparent stone, as big as a fist, and there were four or five pieces wrapped in cloth.

The sulfur is also a large whole, about the size of a plate, and there is a pungent smell in the hand.

Only sawdust Yunniang let the space burn into charcoal, and found a dagger to scrape everything out! It is packed into a bamboo tube according to different proportions.

Yun Niang didn't appear for three days in a row, and the daily food was put outside by Han Shuyan, and then Dabao came out and took it in, and then lay at the door to rest, looking at the person in front of him intentionally or unintentionally.

Today, Han Shuyan has not seen Yun Niang come out for the third day, and he stood in front of the tent with some worry and did not go out, looking at Dabao outside the door, his eyes flashed with worry.

If Yun Niang hadn't repeatedly said that no one was allowed to enter, Han Shuyan would have been unable to bear it a long time ago!

Suddenly, Dabao lying on the ground stood up, his shiny fur shining, turned his head to look in the direction of the tent, and then the tent was opened from the inside, and Yun Niang, who was carefully holding the bamboo tube in his hand, walked out and counted about a dozen or so, all of which were sealed with strips of cloth, and he couldn't see what was inside.

Han Shuyan's eyes lit up, his body moved with his heart, and he floated in, looking at Yun Niang, who was holding the bamboo tube in front of him, and screamed lingeringly.

"Girl!"

"Well, Han Shuyan, hurry up and get a few for me, don't fall to the ground! Take you to see the magical stuff in a moment! ”

Yun Niang, who was talking, had a faint smugness on her face, and she was also a little excited in her heart if the improvised explosives she made could work! Let Han Shuyan take her out of place and ride to a remote place, so as to try the effect.

In a barren yellow sand and stone, Han Shuyan took Yun Niang on a war horse and went to the remote mountain, because Yun Niang said that she wanted to find a secret place and could not be discovered, so Han Shuyan took Yun Niang to the stone mountain on the border.

It's barren and inhabited, surrounded by vast plains, with potholed mountain roads and sand and gravel!

The cold wind on the border was like a knife, blowing on Yun Niang's face, so that Yun Niang bit her lip and could only endure it! I can't even open my eyes, instantly! Yun Niang fell into a warm embrace, Han Shuyan pulled the black cloak behind him to the front, and pulled Yun Niang into his arms to block the cold wind outside.

Yun Niang suddenly felt warm, and subconsciously spit out the cold air in her chest, and smelled the faint musk in front of her, with a hint of Han Shuyan's unique breath in the unique cold fragrance, which made Yun Niang's hand holding the bamboo tube in the cloak tighten, and her eyes leaned on Han Shuyan's chest in the dark, listening to the orderly heartbeat in her ears.

Feeling a faint exhalation coming from his chest, Han Shuyan sat on the horse's back with his eyes lowered, looking at the little person in his arms, not knowing what he was thinking, but a trace of flushing slowly crept up on his ears.

About an hour or so, Han Shuyan tightened his horse's belly, and when he stopped the horse, he heard a weak voice coming from the words.

"Han Shuyan, have you arrived?"

"Well, it's here!"

Unveiled the cloak and helped Yun Niang get off the horse, Han Shuyan directly draped the cloak on Yun Niang.

"Is it possible here?"

"You don't have a fire fold with you! I'm going to use it in a moment! ”

"Bring it!"

Yun Niang asked Han Shuyan to lead the horses farther away and tie them to the spot, otherwise Yun Niang was afraid of scaring the horses away for a while, and how could they go back then.

On each bamboo tube, Yun Niang has engraved the digital ratio with a dagger, and today's task is to blow up all ten bamboo tubes, and only then will I know which one ratio can be used!

Finding a safe location, Yun Niang wrote down the proportion of the first bamboo tube, took down the fire fold and ignited the cloth on the outside of the bamboo tube, and fled from the place as fast as possible!

Han Shu didn't know what to say, picked up Yun Niang and left with light skills, and fled to the boulder a hundred meters away, about five minutes or so, only to hear a bang in front of him, a burst of green smoke, and a faint smell of sulfur came from the air.

"What is this?"

Looking at the green smoke floating in the distance, Han Shuyan turned his face to look at the disappointed Yun Niang and asked curiously.
