After traveling through time, I rely on force to survive

Li Qingqing looked at Xie Xuanan, who was on guard, and could only say, "I want you to buy some sulfur and saltpeter for me."

"What do you want these for?" Xie Xuan'an was a little puzzled.

"So I can buy it?" Li Qingqing was delighted when she heard it.

She had previously looked up books in the space and discovered an item called black fireball that could replace later explosives. If she could successfully make it, she would no longer have to worry about the threat from those bandits.

The key raw materials for making black fireballs are sulfur and saltpeter. She was not sure whether Dayuan Kingdom could easily find these materials, but Xie Xuan'an's reaction just now seemed to imply that these items were not difficult to find.

Therefore, Li Qingqing did not answer Xie Xuanan's question, and quickly asked again, "Can I buy it tomorrow?"

Xie Xuanan looked at her anxious look, feeling somewhat helpless, but he still thought about it seriously, and finally said:

"Yes, it can be delivered to Qiushui Town as early as tomorrow afternoon."

Li Qingqing was very happy to hear this. She solemnly reminded:

"It would be best to assign two teams to purchase these two items to avoid attracting unnecessary attention from those with ulterior motives."

"I understand. I will handle it carefully." Xie Xuan'an nodded.

But I was thinking, this woman bought these materials at this time, could it be that she wants to make some pills?

Xie Xuan'an knew that Li Qingqing was a doctor, but he didn't know that sulfur and saltpeter could actually be used to make powerful black gunpowder, a thing that was unheard of in the Great Abyss Kingdom.

Li Qingqing was in a very good mood at the moment. Seeing that Xie Xuanan was a little confused, she explained in detail:

"Yi Mo once copied many books and accidentally got a secret recipe. It is said that there is a black fireball that can kill countless enemies once it is made. Therefore, I plan to use these materials to try to make such a thing to drive away the bandits."

Li Qingqing lied and put the blame on Zhou Yimo. He would cover it up for her in the end anyway.

After hearing this, Xie Xuan'an's eyes flashed with surprise.

He remembered that when he visited Dean Bai, Dean Bai also mentioned that Zhou An was knowledgeable. Since Zhou An knew this secret recipe, its authenticity was beyond doubt.

Xie Xuanan pondered for a moment, then asked, "Are you sure about the method of making this black fireball?"

Li Qingqing smiled confidently and replied:

"Although I've never made it myself, the recipe is very detailed. As long as I have all the ingredients, I'm confident I can make it successfully."

Xie Xuan'an nodded and thought secretly in his mind.

Now the defensive works are being carried out intensively. Even if the black fireball cannot be produced, it will not delay the normal progress of the defensive works.

If this black fireball is indeed as powerful as Li Qingqing described, it will definitely be of great use on the battlefield. Brother Yun Jing will be very happy when he learns about it.

Thinking of this, Xie Xuanan smiled with his peach blossom eyes, and asked with some anticipation, "Can we make this kind of black fireball in a short time?"

Li Qingqing pondered for a moment, smiled and nodded,

"Time is tight, but it's not impossible. As long as you purchase the materials tomorrow, and we borrow some manpower from Mu Yunjing, we will be able to produce the first batch of black fireballs within two days."

"Okay, this matter must be kept secret and must not be known to outsiders." Xie Xuan'an nodded quickly after hearing Li Qingqing's affirmative answer.

He felt that since Li Qingqing asked Mu Yunjing to borrow the shadow guard to help, she must be worried about the news leaking out.

"Of course. This matter is of great importance. The production process needs to be kept absolutely confidential. Once leaked, it will cause unnecessary trouble!"

After the two of them discussed it, Xie Xuan'an hurried to arrange the purchase.

Since these two important materials could not be found in Qiu Shui Town, they could only be purchased in Yuntai County or other counties. Therefore, Xie Xuan'an quickly assigned his capable subordinates to set off in different directions under the cover of night.

After learning that the source of sulfur and saltpeter had been found, Li Qingqing felt much more relaxed.

She immediately found Zhou An, also known as Zhou Yimo, and said anxiously, "Yimo, I need you to write a prescription for me immediately. I want to give it to the village chief."

Zhou Yimo looked at Li Qingqing's anxious eyes, feeling somewhat helpless, but with a doting look in his eyes, he smiled and led Li Qingqing to the room.

Zhou Yimo picked up the pen, and Li Qingqing began to dictate, writing down the kiln firing method of charcoal making in detail.

As soon as she finished writing, Li Qingqing couldn't wait to take the prescription and said, "Wait for me, I'll be back soon."

Zhou Yimo: ...

Li Qingqing turned and left like the wind, taking the recipe with her to find the village chief of Lihua Village.

"Village chief, I need a batch of charcoal tomorrow afternoon, so I have to start making it tonight. But I want you to select two trustworthy villagers to be in charge of making the charcoal. Once they master the technique, they'll be able to increase their income by selling charcoal during the winter."

"Okay, I'll have them give you the charcoal tomorrow afternoon!"

After hearing this, the village chief's eyes flashed with surprise, and then he took the prescription and turned to leave.

Li Qingqing breathed a sigh of relief and decided to wait until tomorrow to deal with the remaining materials.

She turned around and went back to Xie Xuanan's house, where Zhou Yimo was still waiting for her explanation.

As soon as Li Qingqing stepped into the hall, she saw Zhou Yimo leisurely drinking tea. When he saw her come back, a trace of grievance appeared on his originally calm face.

Li Qingqing: ???

Li Qingqing felt a little guilty. She quietly found a chair nearby and sat down. She had been very busy recently and her calligraphy practice had been sporadic.

This time he was in a hurry to find Zhou Yimo, mainly because he was worried about her handwriting and was afraid that the village chief would not be able to recognize it.

"Madam, why are you in such a hurry to write a prescription for the village chief?"

As Zhou Yimo smiled, the trace of grievance disappeared in an instant, as if it had never appeared at all.

Seeing that Li Qingqing had sat down, he immediately stood up and poured a cup of tea for Li Qingqing.

Li Qingqing coughed lightly and suddenly felt a little uncomfortable.

She told him about her plan to make a black fireball, and then said, "If Xiao Xie asks, just say you learned it from ancient books."

After hearing this, Zhou Yimo frowned slightly, but soon relaxed again.

The black fireball that the lady mentioned, if it is successfully made, will be a matter of great importance, and he really doesn't want to take the credit from the lady.

But if I don't do this, I'm worried that my wife's secret will be known by others.

He would keep this secret for his wife no matter what.

Zhou Yimo weighed the pros and cons in his mind and decided to acquiesce. If that didn't work, he would just pretend he knew nothing. In short, he would reveal any information his wife thought could be revealed, and wouldn't say a word about anything that shouldn't be revealed.

Well! I won't tell you even if you kill me.

As the night deepened, torches were still lit everywhere in Qiu Shui Town, and craftsmen were working hard to build the gate.

Li Qingqing took advantage of the night to quickly move all the blue bricks, lime and other materials to the open space, and took out some bamboo poles and piled them together.

In the early morning of the next day, Li Tiezhu heard that the blue brick materials had arrived, and quickly took a group of people to start building walls and setting up bamboo frames.

No one suspected it and thought someone had delivered it in the middle of the night.

Only Xie Xuan'an and Mu Yunjing were slightly startled for a moment, but they both remained silent tacitly and did not raise any questions.
