Lu Yanzheng looked at her apologetically and said, "Yes, Prince Yong's 30,000 troops are heading towards Yongshan County. I have already notified Qin Shen to bring 20,000 border troops to support us. Tomorrow I need to take these 500 men to the border between Yukang Prefecture and Qiongzhou."

This was a serious matter, and an urgent one at that, so Jiang Qinyu naturally had nothing to say. After a moment of silence, she finally spoke, "Then take care of yourself, and don't let it happen again like this time."

It was only at this moment that she understood why Lu Yanzheng had brought so many people back to Dingshui Village, because he knew that only in the village could they get the best rest.

Apart from Dingshui Village, even at the county government office, Lu Yanzheng dared not sleep as soundly as he did at home.

Having figured this out, Jiang Qinyu suddenly felt a surge of joy. The feeling was subtle, and she didn't know how to describe it, but she couldn't suppress it or express it accurately.

“Okay.” Lu Yanzheng didn’t say much, but nodded solemnly in agreement.

The reason he was in such a sorry state this time was because he went to the capital to meet Xiao Rui, and on his way back he learned that Prince Yong had sent 30,000 troops to Yongshan County, which forced him to rush back.

Jiang Qinyu wanted to take the bowls away, but Lu Yanzheng stopped her, saying, "I'll do it."

For some reason, Jiang Qinyu had no intention of being polite at all at this moment. Instead, the thought of "men are supposed to do housework" popped into her mind.

Lu Yanzheng took all the dishes to the kitchen and washed them as well.

Everyone else in the house was asleep at the moment, so he moved very quietly and didn't disturb anyone.

When he returned to the bedroom, Jiang Qinyu asked, "You sent border troops to support Yongshan County. Won't there be any danger in the city over there?"

“Not for now,” Lu Yanzheng closed the door, strode over and sat down on the edge of the bed. “Dayuan and Xiqiang haven’t made any moves yet, probably because they were stunned by the new weapon you gave me.”

In fact, he was also on guard against the area outside the pass, but now that the threat of Prince Yong was imminent, he had no choice but to risk sending 20,000 men over first.

Jiang Qinyu pursed her lips, wanting to say that she actually had something even more powerful, but thinking about whether it would be a blessing or a curse if it were put into use, she hesitated and didn't speak.

This wasn't something the system gave her; it was a liquid explosive that she had memorized herself, and it was more powerful than gunpowder.

Raw materials can be obtained here, and mass production is also possible, but transportation is a huge problem. One wrong move and you could blow yourself up. She didn't want Lu Yanzheng and the others to take that risk.

Lu Yanzheng noticed her hesitation and thought for a moment before putting his hand on Jiang Qinyu's shoulder and asking, "Is there something you can't tell me?"

“No, it’s just…” Jiang Qinyu hesitated for a moment, but ultimately decided to give the choice to Lu Yanzheng, “I also know of a liquid explosive…”

She briefly explained the situation with nitroglycerin, emphasizing her concerns.

After hearing this, Lu Yanzheng suppressed his excitement and said in a deep voice, "You don't need to worry about any of this. The people at the Ordnance Bureau will handle it. But... is it too late now?"

“A small quantity is fine,” Jiang Qinyu nodded, “but if you want to make a large quantity, I’m afraid it won’t work.”

After all, the raw materials for making nitroglycerin in this era need to be purified, and purification requires some special filtration and distillation equipment, all of which take time to make.

Lu Yanzheng smiled with bright eyes: "A small amount is fine, we can talk about the large amount later."

As far as he knew, Prince Yong also possessed gunpowder weapons, which were derived from improvements to thunderbolts, and their power was similar to the improved version of thunderbolts they had used before.

Now that Jiang Qinyu has provided new explosives, he has to make them, not for any other reason than to deter Prince Yong.

"Alright, I'll write down the specific production method and the materials you'll need for you." Jiang Qinyu was relieved to hear this.

She immediately took out paper and pen and started writing and drawing.

As Lu Yanzheng watched, he suddenly smiled.

"What's wrong?" Jiang Qinyu asked, tilting her head to look at him with a puzzled expression.

Lu Yanzheng ruffled her hair and said, "Does this count as me living off my wife?"

Ever since he met Jiang Qinyu, it seems that Jiang Qinyu has solved all the major problems for him.

Of course, it's not that he couldn't solve the problem without Jiang Qinyu, but rather that if he were to solve it on his own, it would be more troublesome, take longer, and the result might not be as good as it is now.

"So, do you like being a kept man?" Jiang Qinyu asked, raising an eyebrow.

Lu Yanzheng's lips curled up even higher, "Although I have very good teeth, I am more than happy to live off my wife."

His words made Jiang Qinyu laugh, and she covered her mouth and said with a smile, "If Qin Shen and the others knew what you said, they would probably laugh at you for the rest of their lives."

“Let them laugh, they’re just jealous,” Lu Yanzheng said dismissively. “If they’re so capable, let them find a wife who can make them live off her.”

Jiang Qinyu: "..."

What could she say? She could only silently light a candle for Qin Shen and the others.

However, Lu Yanzheng's words stirred up that feeling she couldn't suppress in her heart again, so Jiang Qinyu quickly turned her head and continued writing and drawing.

...

The next day, before leaving, Lu Yanzheng told Jiang Qinyu that the night before, they had encountered a group of refugees on the road. However, he found their escape suspicious, so he grabbed them and interrogated them. He learned that they had come to rob Dingshui Village, so he immediately arrested them all, tied them up, and sent them to the county government.

"It's a good thing you took them to the yamen, A-Zheng, otherwise we don't know how much we would have worried about them coming back for revenge." Village Chief Li patted his chest with lingering fear.

That night, if they had more people, they could have easily captured all those people and handed them over to Lord Wei.

But there were too few of them, and he really didn't dare to take the risk, so he let the group leave.

Lu Yanzheng said, "There should be more refugees coming during this period. If you don't want to accept people from other places, you can keep all the refugees outside the village. If there are any problems, send someone to find Magistrate Wei, and he will handle it."

"Okay, okay, I've got it." Village Chief Li nodded repeatedly, then took Lu Yanzheng's hand and said, "Yanzheng, you must be careful out there and take good care of yourself. For no other reason than to think of your parents and wife back home, okay?"

Lu Yanzheng nodded in agreement, "Thank you for your concern, Uncle Village Chief. I will be careful."

Chen and Old Man Lu looked at Lu Yanzheng with reluctance. They had already said everything they needed to say at home, but Chen still couldn't stop wiping away her tears.

"Father, Mother, Uncle Village Chief," Lu Yanzheng glanced at the people who came to see him off, cupped his hands to everyone, and finally looked at Jiang Qinyu, "and everyone else, please take care in the village."

After saying that, he mounted his horse and led the way out of the village.

Behind him, five hundred cavalrymen followed in an orderly fashion.

The soldiers had already said goodbye to everyone early in the morning. Although they had only spent a day and a night together, each of them felt the warmth of the villagers of Dingshui Village and developed a special affection for the place.

Jiang Qinyu supported Chen Shi and watched Lu Yanzheng's departing figure, remaining silent for a long time.
