It is very simple to make cement by the civil method. First mix limestone, clay, and iron ore powder in proportion. This mixture is called raw material, and then calcined. After calcination, it is called clinker. Grind the clinker and gypsum together and mix it in an appropriate proportion to become cement.

As for gypsum, there is one in Hongye City, so Zhang Feng doesn’t need to look for additional gypsum ore.

To the west of Hongye City, there is a cave for making pottery. Zhang Feng asked his servant to transport the raw materials to the cave for calcination.

These servants are all Zhang Feng's slaves, and they are extremely loyal to Zhang Feng and are not afraid that they will leak the cement production method. Besides, Zhang Feng asked each of them to be responsible for a small part of the complete steps, and they didn't know.

Of course, there is also the most important issue of appropriate proportions. Only Zhang Feng knows what is appropriate.

Soon, when it was dark, the cement was tinted out.

But it is not a success now. You should wait for about ten hours to see how the cement is hardened, but Zhang Feng feels that there should be no problem.

The speed of building city walls in another world is very slow, and one of the important reasons is the absence of cement.

If cement is used as a binder, the efficiency will definitely be greatly improved. After all, cement sets quickly, and after solidification, it is strong and hard.

While directing the servants, Zhang Feng thought about what kind of city wall to be built.

Meanwhile, the castle entrance.

Dozens of soldiers lined up and Baker and two soldiers came out of the castle with a lot of things in their arms.

"Everyone performed well today. This is what the city lord rewarded us."

Baker didn't say much, after all, real rewards work more than much words.

The reward is food, each person has a pack of instant noodles, a ham sausage, and a bag of pickled vegetables.

Not to mention Zhang Fengkou, the main thing is that rare things are precious. If you give too much things, it will be worthless.

Zhang Feng estimated that after these soldiers received these "benefits", some people would definitely buy them at a high price, and they would most likely sell them.

For soldiers, this is a large amount of income. For those who buy, this can satisfy some of their own desires and everyone will get what they need.

The reality is similar to what Zhang Feng thought. After these soldiers received the reward, they did not hide it, and someone soon discovered it.

While they were changing shifts and resting, a large number of merchants seemed to smell the fishy cats, and they all offered high prices to buy the things in the hands of the soldiers.

Of course, buying a bag of instant noodles with a gold coin will definitely not be available again. After all, these merchants are not as rich as Valen, but at least there are dozens or even dozens of silver coins.

In other words, the soldiers' reward this time is worth at least a few months' salary!

The treatment of soldiers naturally aroused the envy of many people, and even caused a wave of military service...

...

Back at the castle, Caroline had already prepared the meal and was waiting for him, but Zhang Feng was a little surprised when he saw the wolf-eared lady sitting obediently at the dining table.

"Huh? Why are you here?"

Before Zhang Feng tinkering with the cement, he had already arranged Amy's residence - a small building not far from the castle.

Because Amy is an orc, Zhang Feng didn't know whether she refused to live with humans, so he divided the small building to her to avoid being disturbed.

But she didn't expect that she didn't leave.

"Hmph! I won't leave!"

Amy snorted.

Zhang Feng looked at Caroline, and Caroline said softly:

"She said she was afraid of living alone and wanted to live in the castle."

"Did you promise her?"

"Isn't this going to discuss it with you? I think it's not impossible to have so many rooms in the castle..."

Zhang Feng looked at Amy and said:

"Okay, you can live anywhere, respect your choice."

He was very suspicious that Amy wanted to live in the castle for free for food and drink.

But Zhang Feng doesn't care. He just prepares a pair of chopsticks anyway.

“Is there enough food?”

Because Amy is here, naturally, the food cannot be prepared for only two servings.

"I prepared a lot, it should be enough."

Seeing plates of delicacies being served, Amy stared at her, and her tail shaking from time to time.

Zhang Feng is actually very curious about the difference between the body structure of the wolf-eared lady and humans, and he really wants to study it!

Especially her ears and tail, she was furry and wanted to masturbate too much. If she hadn't been afraid of not being able to beat her, Zhang Feng would have wanted to get started directly.

"Ahem, that Amy!"

"what!"

Looking at Zhang Feng's malicious look, Amy said vigilantly.

"I'm curious about one thing, will you transform into a human being, or a beast, such as whether you can become a wolf?"

Amy looked speechless.

"I don't know, I won't!"

"That's how..."

Zhang Feng showed a hint of disappointment in his tone, and was disappointed when he failed to see the "transformation technique".

"Forget it, eat and eat!"

Although the wolf-eared lady could not help it, she picked up the knife and fork until Zhang Feng took the lead in moving the chopsticks.

It can be seen from this that orcs are not unceremonious species. At least Zhang Feng did not feel anything annoying in Amy.

After dinner, Caroline asked the servant to pack up a house for Amy to live in. Her room was close to the window and looked out, and she could see Pangda.

Amy was naturally satisfied.

"Give it, this is your toiletries."

Caroline took out a set of towels, toothbrushes and other things and handed them to Amy.

Amy looked at the things in her hand and was a little confused, not knowing what she was doing.

"I'll teach you how to use it."

"good."

Zhang Feng took a shower and lay on the soft big bed, with some random thoughts in his mind.

When will the horse thief come?

Can the newly built city walls block the horse thief?

What do other orcs look like except for the wolf-Eared Girl?

Can those jade be sold for money? Will people in this world like jade?

I have been in another world for almost five days. Is there anyone in another world looking for me?

...

As he thought about it, Zhang Feng felt a sleepy feeling coming and was about to fall asleep, he suddenly heard a knock on the door.

Dongdongdongdongdongdong!

"Mr. Zhang Feng, have you... been asleep?"

Hearing Caroline's soft and weak voice, Zhang Feng's sleepiness suddenly disappeared.
Chapter completed!
