Gulong Ayuken is coming, and he is coming on behalf of the church.

Things are a bit troublesome, and he still wants to farm well.

But...... It should be a long time before it comes, after all, the letter was written by an ancient dragon, and an ancient dragon said that it would come soon, according to the human concept of time...... Let's wait for half a year, people can sleep for half a year when they take a nap, but I don't know if Ayuken is as lazy as Elaine, if that's the case.

"Well, sir, what are we going to do? What's going on with the daughter here? This missionary, has a daughter on our side? Do you want to ......" Bai Si thought about whether to cut the grass and eradicate the roots, and made a downward gesture to Lu En.

Lu En was surprised, what did this little girl go through, she was so ruthless?

"Ahem, what do you think." He played a white brain: "His daughter is Elaine, the one who is helping us now, are you embarrassed to do it?" ”

"Huh? Is it the big sister who is covered in gold and is very rich at first glance? Is she a member of the church? Bai frowned: "Sir, now that we are few people, we should keep the team pure, although she looks very good, but if it has something to do with the church...... I think it's better to clear it. ”

"That's right, but don't worry, she can be trusted." Lu En did not reveal Elaine's identity, after all, she was a dignified holy dragon, and if she said that the camp might be dispersed, at least, the high-level vampires might not be able to accept it, unless Elaine handed over a petition and killed the people of the church, but that was not what Lu En wanted to see, he had other arrangements.

"Okay, I'll arrange it, don't worry, is there anything else?" Lu En changed the subject.

Since the person in charge said so, Na Bai didn't say much, so he calmed down his mood and began to report on the situation in the camp recently.

"Recently, our existence was discovered by a group of brute beasts, the orcs can't deal with it, this is the twenty-sixth group recently, although there are no dead people, but Sister Kara's energy has been seriously dispersed, I suggest, you need to build some fortifications around, you don't need too much, just a little rejection of horses and pits, Mr. can use magic to make a trap, and it won't take much time to reject horses." Shiro said as he gestured with his hand.

"Trapped? Rejection? Lu En touched his chin with his hand.

"Well, you can do this now, but it's not necessary, I've been busy these days, I don't have much time, I've been dealing with the people in the church every day, and I don't have much time with the high-level vampires, now that I have time, I'll teach you something that you can use." Lu En took out a pen and paper, began to write and draw, and then tore it into notes.

"Go and prepare a little clay, lime, there is a river nearby, it shouldn't be difficult to collect, by the way, their workshop should not have been built yet, and you also need some slag from the blast furnace before, to build things, I have something better than stone, called cement." He said as he wrote down the materials that needed to be prepared.

"Cement?" Bai tilted his head, this name is weird.

However, since the gentleman had said it all, it must have been useful, and Shiro took the note he had written, and began to prepare those things.

The next day, Bai Yi didn't sleep all night, and took people to collect materials everywhere, and took away what was in the warehouse, and went to find what was not in the warehouse, and finally prepared all the materials before dawn, and the quantity was not small.

Lu En also didn't sleep all night, mainly because of the relationship between the boundary monuments, things that can rewrite the concept of the universe are not ordinary, in order to be able to finish this within a month, Lu En used himself to build this boundary monument, eighteen boundary monuments, which is equivalent to eighteen Lu En standing on the border, his mind is divided into nineteen parts, and he is over there at any time, the advantage is that once someone crosses the line, he will immediately know, the disadvantage is that before he takes his mind back, he doesn't want to sleep, meditate, or do something that extremely needs to be focused, and distract nineteen partsHow do you focus?

As soon as the morning dawned, the sun rose slightly, and Lu En stood under the morning light, accompanied by Bai, and there was a monster hybrid.

Monster hybrids are human-mixed minotaurs, which look no different from normal minotaurs, with a bull's head and hooves, and a slightly bowed body, just a little shorter, but they are tall and powerful for humans, with a strong body, two meters and five meters tall, and a normal minotaur is about three to four meters tall.

His name is the big tower, he is one of the monster hybrids in Larante before, and now he is the most powerful stonemason among those monster hybrids, very talented, and has reached Stonemason 2, but he only broke through a few days ago, and he is the only level 2 among all monster hybrids, because recently he has been mining the stone quarry near this wasteland day and night, preparing for the expansion in the future, a lot of practice, the right talent, plus some luck, made him a level 2.

"Cement is a good building material, it can also be used as a binder for stone, and the raw materials are very simple to get, very cheap and efficient, the specific manufacturing method has been given to you, I will show you now."

The raw materials brought in are all genuine "raw materials", which have not been milled, all of them are lumpy, and the slag is still hard.

Normally, if you want to grind these, you need a lot of human physics, but a magic 9, then you don't need it, magic itself represents a higher level of productivity, otherwise what are the majestic buildings of Larrant and the imperial capital built on? By the level of technology of this magical medieval? Of course not, it depends on advanced production technology.

In Lu En's view, this world is not backward at all, on the contrary, this world is unbelievably advanced, human beings have a full 10,000 years of civilization, the human beings in this world are not necessarily stupider than the humans in the original world, they are just too lazy to study physical chemistry, their real technical power lies in magic, those magic instruments are the best proof, they can tear apart the teleportation of space, in the original world, this technology is still left in the "conjecture" column of the computer folder in the laboratory, and this side has been realized, It can even be used on a large scale.

Because of the existence of individual power, all the technology and development of this world are limited to the upper class, and no one cares about the lower class people at all, so they have maintained the so-called magical medieval living standard for thousands of years, ten thousand years, and they can't even set off a revolution, because even if they set off a revolution, as long as they come to two or three levels 9, they will be extinguished when they raise their hands, and the fluttering in the small ditch is not important, the population is just more than a large number of people, and there will be more high-level professionals.

Thinking of this, Lu En sighed, that emperor was terrifying, he didn't look like a professional, but those eyes, which seemed to contain an abyss.

He couldn't figure it out, he couldn't even fit the abyss in his eyes, why couldn't he hold that little thing?

But this is not important, leaving it behind, Lu En said to Bai and Da Ta: "Look, remember the process, this thing is very important." ”

Hearing Lu En's saying that it was important, the two of them were already very nervous, but at this moment they became more solemn, and they looked at Lu En's approach without blinking.

"First of all, grinding, you are a stonemason, this should not be a problem for you, you don't need to grind so fine like me, the coarse point is just a little less strong, but a little finer grinding is not a bad thing."

As he spoke, the magic in his hand activated, and the magic power gathered, creating a large pool of elemental ice that was constantly stirring and grinding, which was said to be ice, but actually did not melt, but was extremely strong, and it was very effective for grinding.

This is the Ice Pool Technique, which was originally intended to destroy some sturdy armor, and with this move, it is especially useful against some iron turtles, but it is also very good when used to grind raw materials.

Soon, the raw material was ground into powder, extremely delicate, Lu En blended according to a certain proportion, and said in the process of blending: "Lime is the largest raw material used in the production of cement, and the particle size is larger, the hardness is higher, so it is difficult to grind, this point should be noted, it can not be too fine, but if there are particles, it will be more troublesome, and it will affect the final finished product." ”

As Lu En spoke, he began to knead the raw materials into spheres with the hands of a mage.

Bai and Da Ta hurriedly wrote it down, they all knew that this could be alchemy, and alchemy is a step that cannot be wrong, otherwise it may die, this is an ancient and revered art, it is the art of mixing all kinds of magical substances, only a few people who are desperate, not only smart but also not afraid of death, can be lucky enough to master this skill.

There is a well-known joke about alchemy, the last words of an alchemist, whose last words before his death were: "Remember, only three drops of polar oil can be added here...... Damn it! Run away, everyone! ”

Lessons from the past, so they are becoming more and more dignified, the steps of alchemy must be good at all, otherwise they are joking with life.

"Then, it's clinker firing, and you can see it clearly." The elements in Lu En's hand turned again, and the original deep pool of ice suddenly burned in the blink of an eye, the yellow flame ignited with a pungent smell, and the faint light flashed in the morning light, and the single shadow quickly turned into hundreds and thousands, and the raging flames emitted a blazing rush from Lu En's hand and began to burn.

Lu En uses the calcination method of vertical kiln, which has long been eliminated, waste of resources, serious environmental pollution, and poor effect, because it is a static calcination, many times, the outside of the raw meal has been sintered and the reaction has been completed, the inner layer may still be in the solid phase reaction, and the core part may still be in the decomposition of calcium carbonate, the heating is uneven, the product quality is poor, the output is low, but the advantage is that the technical content is also very low.

The better method is of course the calcination method of the rotary kiln, the use of rotary calcination equipment, the cement material in the rotary kiln can roll up and down freely, the cement output and quality are greatly improved, the energy consumption and production cost are greatly reduced, and the clinker produced in this way has more pores, easy to mix, the composition is stable, the uniformity and quality are all higher than the vertical kiln cement, but that requires the rotary horizontal calcination equipment, which is not to think about it for the time being, only in the dream.

"These two steps are the most important, the first is the calcareous raw material, the clay raw material and a small amount of correction raw material after crushing, according to the ratio I gave you, grinding, and matching into a uniform raw meal, and then calcined into clinker, the ratio and temperature are written in the notes I gave you, remember, the temperature must be stable, not up and down, but this requires a stable source of coal...... Well, that's a question, do you have any ideas? The trade route has not yet been opened, and it is estimated that it will not be opened in the near future. Lu En asked as he forged cement to control the heat.

Bai didn't know the answer, frowned and thought, now is the period of controlling the heat, but he doesn't need to pay too much attention to the clinker in calcination.

However, the big tower suddenly spoke: "Sir......"

He called Mr. Luen, not Wang, because the title was a hybrid of monsters that Larrant came out of, and everyone called him Sir, as if they could tell where they came from.

"Do you have a way?" Lu En looked at the tower, the minotaur was a meter taller than him, and he had to look up to see it directly.

"Shall we have the people of the church to help connect the trade routes? I have heard that if it were a diocese, the Church would have opened up the road to facilitate the pilgrimage. Data said.

"It's impossible, isn't that just showing weakness to the church, so Mr. ......fought with them." Shiro retorted, but at this point, her voice became smaller and gradually stopped, these things were not said to ordinary members, and saying it now might cause panic.

These ordinary members only know that they are here to open up wasteland, and they can no longer endure the white eyes and oppression in the city, but they do not know that they are here to fight against the church...... If you knew, you might be scared silly.

Seeing her stop, Da Ta continued to say suspiciously: "Is there anything strange about showing weakness?" Is there anything better than the church? Moreover, I have a pretty good impression of the church, I used to be unable to afford to eat, but I went to the church and ate a lot, and they didn't need money to give alms, anyone could go, as long as they knelt there and followed the scriptures. ”

After saying that, he grinned and said, "But I still like it here!" Although there is food over there, I always feel uncomfortable, there are brothers here, and there are goals to strive for, and my skills are also learned here, sir, we can build a city like Larante here, right? ”

"What do you think, the city we are going to build...... Much larger than Larante. Lu En also replied, and at the same time, because of the magic flame, the cement clinker in his hand was almost calcined.

It's much faster than in the stove.

Lu En broke the clinker in his hand into pieces, put it on the ground, and used the field wall to shape it, and made a water mass by the water making technique.

"Well, you see, it's this special powder, called cement, and stone, which can be used to make extraordinary defenses, and can also be used to build houses." Lu En hadn't added the water yet, but a special smell was already emerging.
