The main raw materials of gunpowder are sulfur, saltpeter and charcoal, and then according to the ratio of 75 percent saltpeter, 10 percent sulfur and 15 percent charcoal, the most primitive gunpowder can be obtained.

On the way from exile, she had already collected a lot of sulfur, plus Rong Shaoyu had also collected some nitrate along the way, although it was not much, but it was enough, and as for charcoal, she still had a lot of space.

Therefore, the materials have been almost prepared, and now it is only necessary to purify the sulfur stone and white nitrate with soil.

The storage of white nitrate is relatively simple, just put it into the water tank, soak it with water, and then remove the scum, and then put it into the pot and add water to boil until it is completely dissolved and fully concentrated, and then pour it into the container, after one night can precipitate crystals, if you want to have good nitrate, you need to add water and boil again, so that you can get good white crystals several times.

As for the sulfur stone, it needs to be put into the pit of the earth to be calcined, burned to a certain extent, there will be golden yellow gas coming out, in advance on the small hole with a bowl with a slot around the bowl, the yellow steam will be condensed along the bowl into a liquid into the surrounding slot, after cooling, it will eventually condense into solid sulfur.

After determining the steps, Murong Qin waved her hand and took out some tools from the system space, fortunately she had everything in the space and lacked nothing, otherwise she would really be worried about it.

When she was busy in the space, Hu Changping and Murong Qingyang were also leading people to clean up the mess outside, so no one in the yamen came to disturb her.

In this hurry, she forgot the time, until the things were almost ready, Murong Qiang was shocked to realize that the time of the night had passed, and after eating a grilled fish with Tuan Tuan to fill her stomach, she washed up again, and then hurried out of the space.

At this time, there was no one in the yamen, and even Murong Chen and his mother didn't know where they went, but thinking of the things and materials needed to make weapons, she raised her feet and went out.

As soon as he came out of the yamen, he saw Zhang Yinwu and Li Yao and others coming.

Li Yao's mood was a little low, and his face was quite reluctant

, "Little Brother Murong, the matter of Yuanling County is over, let's go." "

You... Leaving?" Murong Qin was slightly stunned, it was indeed time.

Although I knew that there would be this farewell, I didn't expect this day to come so quickly.

The birth and death on the way to exile have long made their relationship no longer defined by ordinary friends.

"I will take care of you along the way, Zhang is grateful, but there is no feast in the world, if there is fate, we will meet again in the future, little brother Murong... Don't pass by today, remember to cherish it. Zhang Yinwu bowed solemnly and arched his hand.

Chen Shan's eyes also secretly sparkled with water.

Murong Qin understood their compulsion, and slowly spoke

, "Okay! Brother Zhang, Brother Li, Brother Chen... You have a smooth journey, if you want to come back one day, I welcome you at any time on behalf of Yuanling!" Li

Yao was very sad when he heard this, but he still smiled and said, "Little Brother Murong, you take care of yourself in the future, maybe we will see each other again next year..."

And they will return to Beijing after sending the last of these people to Yongchuan, as for the result, it is not yet known.

Zhang Yinwu didn't feel good in his heart, but he suddenly thought of something and said

, "By the way, little brother Murong, the county magistrate has already ordered someone to register those who are willing to stay in Yuanling County in the government early this morning, I heard that they were specially made into a village, and the village is not far from Yuanling County, Zhao Zuo and Gu Lao's family are also among them, if you want to find them in the future, just ask Lord Hu."

And also...... Regarding yesterday's incident, I have sent someone to inquire clearly, it is the daughter-in-law of the Chen family who is causing trouble, Brother Zhang knows who you are, so he specially asked Zhao Xun to leave his family behind, how to deal with it, you can just watch it yourself.

Murong Qin didn't expect that there would be such a stubble, she couldn't help but be moved in her heart, Zhang Yinwu was a careful person and would always think about her.

After the explanation, Zhang Yinwu decisively took Li Yao and other officials to say goodbye to her, and walked with Zhao Xun to the direction of the city gate with Zhao Xun under her eyes.

It wasn't until everyone could no longer see that Murong Qin put away his sadness, and his eyes became firm.

Yuanling County is her first home, no matter how much wind and rain there is, here, no one can shake it, maybe soon, she and them will finally have a goodbye day, at that time, I hope they will not have so many involuntary and helpless!

In the post station, many exiles who remained here were waiting for the government's arrangement.

Most of the people led by Zhang Yinwu chose to stay in Yuanling, and some of the people led by Zhao Xun also stayed, but only a few people, despite this, there were nearly one hundred and fifty people in total.

She had known that Grandpa Gu's family had stayed here, but what she didn't expect the most was that the down-and-out scholar Shen Ye was also among them.

Shen Ye was still alone as before, looking out of place in the huge crowd, and when he saw her coming, an indescribable light flashed in his eyes, and Murong Qin was a little unable to see through it.

But she knew that this person was extremely smart and talented, after all, he had already been admitted to the Juren at the age of seventeen, and he couldn't find a few in the entire Daling Kingdom, which showed that he was indeed extraordinary.

Such a talent stays in Yuanling County, maybe it is also a blessing for Yuanling County, no matter what, it is better than being sent to that ghost place in Yongchuan County to mine and work as a coolie.

Murong Qin looked around, and finally, his eyes fell on the daughter-in-law of the Chen family.

The daughter-in-law of the Chen family began to panic as early as the moment Zhao Xun left her, and now when she saw Murong Qin, she was a thief with a weak heart, her eyes dodged, and she didn't even dare to raise her head, but when she hugged the child in her arms who obviously looked different from before, a trace of hatred flashed in her eyes.

Murong Qin's face was calm and unwavering, and she raised her eyebrows when she saw the child in her arms.

It is self-inflicted, and you cannot live.

This child was really ruined by her hands.

But this is by no means an excuse for her to report to the gangsters and assassinate her family, especially since Rong Shaoyu is still lying in her operating room after experiencing life and death at the moment.

She, unforgivable!
