The soil method is very simple to make cement, first mix limestone, clay, and iron ore powder in proportion, this mixture is called raw meal, and then calcined, calcined is called clinker, and the clinker and gypsum are ground together and mixed in appropriate proportions, which becomes cement.

As for gypsum, Red Leaf City has it, but there is no need for Zhang Feng to look for gypsum mines in addition.

To the west of Red Leaf City, there is a cave where pottery is made, and Zhang Feng asked his servants to carry these raw materials to the cave for calcination.

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

Of course, there is also the most important issue, the issue of appropriate proportion, what is appropriate, this is only known to Zhang Feng.

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

It's just that it can't be considered a success yet, and you should have to wait for about ten hours to see how the cement hardens to see what the effect is, but Zhang Feng feels that there should be no problem.

One of the main reasons why the Atlas is slow to build walls is the lack of cement.

If you have cement as a binder, the efficiency will definitely be much higher, after all, the cement sets quickly, and after setting, it is viscous and hard.

While commanding the servants, Zhang Feng thought about what kind of city wall to build.

At the same time, the castle gates.

Dozens of soldiers stood in formation, and Baker and two soldiers came out of the castle with a large pile of things.

"Everyone has done well today, and this is the city lord's reward for us."

Baker didn't say much, after all, the real reward was more effective than the amount of words.

The reward is food, a pack of instant noodles, a ham sausage, and a bag of mustard per person.

Not to mention Zhang Feng's buckle, the main thing is that things are scarce and expensive, and if you give too many things, they will be worthless.

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

For the soldiers, this is a large income, and for those who buy it, it satisfies some of their appetites, and everyone takes what they need.

The reality is similar to what Zhang Feng thought, after these soldiers were rewarded, they didn't hide it, and someone soon found out.

While they were resting from shifts, a large number of merchants, like cats smelling fish, offered high prices to buy things in the hands of the soldiers.

Of course, there will definitely be no more gold coins to buy a bag of instant noodles, after all, these merchants are not as rich as Valen, but at least a dozen or even dozens of silver coins are still available.

In other words, this time the soldiers' rewards are worth at least a few months' salaries!

The treatment of soldiers naturally aroused the envy of many people, and even aroused a wave of enthusiasm for being soldiers......

……

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

"Huh? Why are you here? ”

Before Zhang Feng tinkered 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 doesn't know if she rejects living with humans, so he divided the small building to her to save being disturbed.

But I didn't expect her to leave.

"Humph! I'm not going! ”

Amy snorted.

Zhang Feng looked at Caroline, and Caroline said softly:

"She said she was scared to live alone and wanted to live in a castle."

"You promised her?"

"Isn't this going to be discussed with you, I think there are so many rooms in the castle, it's not impossible to ......"

Zhang Feng looked at Amy and said:

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

He suspected that Amy wanted to live in the castle because she was eating and drinking.

But Zhang Feng doesn't care, anyway, just prepare an extra pair of chopsticks.

"Is there enough food?"

Because Amy is here, the food can't just be prepared for two people.

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

Watching the plates of food being served, Amy stared at it with a blank eye, and her tail wagged from time to time.

Zhang Feng is actually very curious, what is the difference between the body structure of the wolf ear girl and humans, and he really wants to study it!

Especially her ears and tail, fluffy, I want to stroke it so much, if I wasn't afraid that I wouldn't be able to beat it, Zhang Feng would want to get started directly.

"Ahem, that Amy!"

"What!"

Looking at Zhang Feng's ill-intentioned look, Amy said vigilantly.

"I'm curious about one thing, will you orcs transform, that is, completely human, or become beasts, for example, can you become a wolf?"

Amy was speechless.

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

"That's ......"

Zhang Feng's tone showed a hint of disappointment, disappointed that he didn't see the "Transformation Technique".

"Forget it, eat, eat!"

Although the wolf ear mother couldn't help it for a long time, it wasn't until Zhang Feng took the lead in moving the chopsticks that she picked up the knife and fork.

It can be seen that orcs are not an impolite species, at least in Amy, Zhang Feng did not feel any annoyance.

After dinner, Caroline asked the servants to clean up a room for Amy, her room was close to the window, and when she looked out, she could see Fatda.

Amy was naturally satisfied.

"Here's your toiletry."

Caroline took out a set of towels, a toothbrush, or something, and handed it to Amy.

Amy looked at the thing in her hand, a little confused, not knowing what it was for.

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

"Okay."

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

When will the horse thieves come?

Will the newly built walls be able to keep the horse thieves at bay?

Except for the wolf-eared girl, what do the other orcs look like?

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

I've been in the other world for almost five days, is there anyone in the other world looking for me?

……

Thinking about it, Zhang Feng felt a wave of sleepiness coming, and when he was about to fall asleep, he suddenly heard a knock on the door.

Knock knock!

"Lord Zhang Feng, you ...... Slept? ”

Hearing Caroline's soft and weak voice, Zhang Feng's sleepiness was suddenly swept away.

"Nope!"
