Forcing me to keep vigil for your childhood sweetheart? Then I'll leave you.

"I do have something that can be used to repair the city wall, and it's plenty enough."

Seeing Prince Qing's embarrassed expression, Lin Yi put on a mysterious smile.

"If you really have it, just take it out. I'll give it to you no matter how much it is!"

Now we have money but no goods. As long as it can be used to repair the northern city wall, Prince Qing is willing to pay any price.

"It may take a few days. I know the stuff, but it needs to be done."

Lin Yi waved his hand slightly and said, "You can take the bicycle and play with it first."

"Well, that's fine. Here's the money for the bicycle."

Prince Qing personally took out the banknote and handed it to Lin Yi, "You need that thing as soon as possible. You don't know when the enemy will attack again."

After saying this, he stood up and left with the messenger.

"Master, what are you talking about?"

Seeing Prince Qing leave, Xiaomei suddenly became anxious, "Where can we find anything at home to repair the city wall?"

And the portion is large and full?

It’s okay to fool others, but if you fool Prince Qing... and you can’t produce the results, it will be a capital crime!

“There’s always going to be one!”

"It just so happens that I also want to formally renovate our east workshop."

Lin Yi's calm demeanor made Xiaomei even more anxious.

"Master, go and apologize to Prince Qing!"

Xiaomei pouted, looking worried, and couldn't help but pull Lin Yi's sleeve.

"Don't be afraid, aren't the bicycles coming over here?"

The more relaxed Lin Yi was, the more worried and anxious Xiaomei became.

"You don't really think I'm lying, do you?"

Having said this, Xiaomei nodded slightly.

"Okay, then, you help me with the instant noodles and woolen cloth business first, and I'll go find the materials."

Lin Yi said this and went out immediately.

Anyway, the village is operating at full capacity now and is like an assembly line. Xiaomei and the village chief just have to take a look to ensure safety.

Lin Yi went out with a large basket and began to look for various stones in the mountains.

To make cement, you need various stones and clays, which you crush, add water, stir, and burn at high temperature.

So the first step is naturally to find stones and clay.

Soon, Lin Yi dug a lot of soil in the mountains and then picked up a lot of stones.

We only need to make a sample to show Prince Qing, so we don’t need too much material.

The woods and mountains near Niujia Village are full of materials. If you need mass production, you can come and dig them at any time!

Moreover, we can create some flat land near Niujia Village for development...kill two birds with one stone!

Thinking of this, Lin Yi took the basket back and started grinding stones in the yard.

He originally thought that cement could be made in one go, but the process of adding water and grinding made him a little crazy.

The soil is not very hard, but it takes a long time to dissolve in water.

Not to mention stone, to break a stone you need something harder than stone.

To this end, he borrowed the mills used to make flour and soybeans.

After a long period of hustle and bustle, I finally made a pot of cement slurry.

The fire subsided and the cement slurry gradually became thicker. Lin Yi also kept stirring it with a shovel.

"Master, what are you burning..."

Xiaomei had just returned after confirming that the villagers had completed their work for the day, but she saw Lin Yi cooking this pile of mud in the yard. She vomited uncontrollably before she could even finish her words.

"Go back to your room first, it will be fine in a moment."

Lin Yi knew that he couldn't stop stirring, so he could only wave to Xiaomei to go back to her room.

He didn't know how long it had been, but he felt that the mud in the pot was becoming harder and harder to stir, and it seemed to be taking shape.

Then he took a small box and put the cement in it to shape and cool.

Looking back, I realized that I couldn’t keep this pot anymore!

After doing all this, Lin Yi returned to his room to have dinner with Xiaomei.

"Master, what on earth are you doing?"

While eating, Xiaomei asked curiously, but when she thought of that pool of stuff, she felt nauseous and wanted to vomit.

"You'll know tomorrow."

Lin Yi thought that it would take quite some time for the situation to cool down, so he decided to wait until tomorrow morning to check the situation.

While eating, he remembered that there were still a lot of iron ore. If he could get himself a bicycle, it would be much more convenient to go in and out of the city!

But what he thinks about more now are just two words: rest.

The next morning, when Lin Yi went to the yard to see the situation, there was a hint of disappointment on his face.

It does take some time for the cement to cool and set.

Now when you touch it, it is still soft and can be kneaded at will like plasticine.

He suddenly had an idea and took out the unformed cement in the box and made a triangular pyramid.

Then continue to cool on a wooden board.

This thing had a scientific name in Lin Yi's previous life, called anti-tank cone.

After waiting for five or six days, the triangular cone finally cooled and took shape.

That day happened to be the end of the month and also the last delivery of instant noodles.

After that, their army would make instant noodles themselves, and the instant noodles made in Niujia Village would be sold to the people.

"Boss Lin, what the hell is this?"

The freight convoy was about to set off, but Lin Yi was seen carrying a "big lump of iron" with great effort.

"Take this with you."

Lin Yi did not answer, but directly carried the cement cone onto the carriage.

After reaching Liangzhou City, the soldiers took away the last batch of instant noodles.

Because this was the last batch of instant noodles that Niujia Village would sell to the army, Prince Qing was also waiting here.

"Lin Yi, shouldn't you tell my army members about the instant noodle recipe?"

Prince Qing greeted Lin Yi with a smile, but the next second, a hint of doubt flashed across his face, "What are you doing here with a big lump of iron?"

"Move it in first, and you'll know later."

Since Lin Yi said so, Prince Qing ordered people to help Lin Yi move his things into Prince Qing's Mansion.

In the yard, the housekeeper and some servants were also pointing at the big lump of iron, not knowing what it was.

"Daddy, what is this?"

Even Chu Yaoyue, who had just returned, was confused.

"Your Highness, everyone else must leave first."

Lin Yi reminded him seriously.

Prince Qing noticed something and immediately asked his steward to drive away the outsiders.

Then he placed the pyramid in the backyard with his own hands.

The thing was very heavy, but Prince Qing was even stronger.

"Lin Yi, you should tell me what this thing is, right?"

When they reached the backyard and put down the concrete cone, Prince Qing could no longer suppress his curiosity.

"This is called cement. It's the material I mentioned for repairing the city wall."

"More than bricks and stones."

Lin Yi looked confident.

"Can this triangle be used to repair the city wall?"

Prince Qing frowned in total disbelief, but the weight was indeed substantial.

"Your Highness, why don't you try its strength first?"

After Lin Yi's reminder, Prince Qing thought he should give it a try. He immediately drew out a knife and chopped at the triangular cone several times.

Prince Qing thought that his few cuts were enough to break the best bricks and stones, but he saw that there were only a few slight cracks on the triangular pyramid!

Instead, the knife he brought had several large cracks on it!
