After Zuo Hufa led his subordinates to tie up the horse bandits, he noticed some wooden spikes appeared on the gray walls of their sect. He frowned and thought it was a mess, but when he saw the big After the gray stone-like thorn on the position of the head, he swallowed all his words back.

Zuo Hufa turned his head in disbelief and looked at the densely packed wooden spikes on the entire city wall. If the moulds on this piece of the city wall are covered with such stone spikes, let alone attacking the city, the general horsemanship is not good. None of them dared to speed up on the edge of the city.

He couldn't imagine how his young master could do such a miraculous move. These stone spikes seemed to be integrated with the city wall, as if they grew out of the city wall.

Could it be that his young master has been favored by Lie Yanshen?Guardian Zuo couldn't help but think of it.

The right protector watched his subordinates tie up the horse bandits and took them into the city, and came over. The left protector told the right protector his guess, and the right protector looked at the densely packed molds on the wall in obvious shock.

"Blessings of the Lieyan God, I am afraid that the young master has really been favored by the Lieyan God." The right guardian looked at everything in front of him and couldn't help murmuring.

Waiting for him to come down from the city wall of Chu'an, the eyes of the left and right guardians who saw miracles greeted him.

He was still holding a pen and paper in his hand, and it recorded the time it took for the cement to dry. Unexpectedly, the cement was of very high quality, and the time it took to dry it was neither too fast nor too slow. Judging from the column performance, these cements have reached the qualified standard.

It was rare for Guardian Right to not know how to speak. He said to Chu An expectantly, "My young master, I don't know what are those stone spikes outside? They seem to grow out of the city wall."

Originally, the left and right protectors were ready to hear the miracle, but Chu An's answer still exceeded their expectations.

"Those stone spikes?" Chu An pointed to the outer city wall and said, "Those were filled with the gray mud made the day before yesterday. I call it cement now. Those so-called wooden spikes are actually the molds of these cements. After the cement is hardened, it will be like the stone spikes now, the left and right guards should have seen it, didn't you see the cement before you left the day before yesterday?"

The left and right protectors were slightly disappointed after hearing that it was not the miracle of Lie Yanshen, but when they heard that these stone spikes were actually made of the gray mud the day before yesterday, their disappointment turned into excitement.

The miracle of the Flame God will only favor one person, but like these plaster, no, cement can generally be mass-produced.

They have seen with their own eyes that the young master just went to the Gobi to pick up a few gray stones, put them in the kiln for calcination, and then got the gray powder, and the rest of the steps were just adding gypsum and other things and stirring them evenly That's all.

The left protector was rarely excited, and his originally stern face was a little loose, while the right protector looked at the cement kiln standing next to the main hall of the sect with bright eyes.

The left and right protectors were excited for a while, and the right protector who calmed down first couldn't help but asked with some doubts: "I don't know, young master, where did you learn about the method of making this cement? It is impossible not to forget the memory of such a benefit to the country and the people." Being used by the emperor of the Central Plains."

Chu An replied without changing his face: "I saw it in a miscellaneous book. As for why the emperor of the Central Plains didn't find out, it may be because the Emperor of the Central Plains already has Sanhe clay, which is not too different from cement."

The right protector nodded to show his understanding. At this time, the left protector couldn't help asking: "I don't know, young master, how much is this cement cost? Can it be mass-produced? Can it be used by the church members to build houses."

Zuo Hufa, who saw with his own eyes how the master's big knife broke, has no doubts about the solidity of cement. Although a stone house can also achieve the same effect as cement, the energy used to mine stone is not the same as making cement. an order of magnitude.

Chu An nodded and said: "The cost of this cement is not expensive, the only thing that is expensive is the gypsum inside, and other sand and stones are everywhere in the Western Regions, as long as you sift through and pick out the sand and stones that can be used, it will be fine, but the building cement It is fully capable, but there must be supports inside, red bricks are enough, and there is no need to worry about collapse if there is cement bonding."

The congregation on the side looked at each other excitedly when they heard Chu An's answer. They all witnessed with their own eyes how the young master turned the plaster into the current stone spikes. Just now they were still feeling so strong. If the materials can be used to build a house, there is no need to worry about the sandy weather in the Western Regions. Unexpectedly, the dream will come true in a blink of an eye.

The congregation couldn't help looking at Chu An with grateful eyes.

However, Chu An felt a little emotional: "It would be great if there were steel bars, and the house can be built at least five floors above if there are steel bars to support it."

In Chu'an's world, if you don't consider the wind load, reinforced concrete structures can be built as high as you want. Even if you consider the wind load, [-]-story residential buildings can be found everywhere.

Although the cement concrete produced today is only the most elementary concrete and cannot build a high-rise house, if it is supported by steel bars, it is absolutely no problem to have more than five floors.

After hearing Chu An's words, the guardian on the right couldn't help asking: "Young master, I don't know what the steel bars you are talking about are..."

"It's a long stick made of steel. You can understand the steel bar as the skeleton of the house," Chu An said, drawing a schematic diagram of the left and right guards on paper with charcoal at the beginning of the rise, "and the concrete is the skeleton of this skeleton." Flesh and blood, surrounded by steel bars with molds, and then poured with concrete, a house can be built extremely quickly."

Chu An sighed and said, "It's a pity that it is almost impossible to find steel bars." After all, under the ancient salt and iron control, one to three iron weapons for martial arts people was already the emperor's greatest tolerance for them, and it was also the emperor's greatest tolerance for them. The reward for retaking the Western Regions in [-].

Looking back on my memory, the emperor tightened iron controls on martial arts practitioners later on. I am afraid that it is not only by building a relationship with the government that you can use steel bars to build houses.

However, just as Chu An sighed, Guardian Right said soothingly, "Young Master, don't worry, our Lieyan Sect has a good relationship with the government's iron workshop in the Western Regions, and those steel bars should be able to be ordered in the government's workshop." .”

Seeing his young master widen those phoenix eyes as if in surprise, the right protector hooked the corner of his lips and said with a little pride: "Our Raging Flame Sect is a big customer of the government's iron workshop, and every year the congregation replaces it. All the ironware will be sold at a low price to the government workshop, and then exchanged for new ironware, after all, it is not a magic weapon, and selling it directly to the government workshop can reduce the cost."

Chu An couldn't help asking: "Does the government actually allow the Western Regions to buy weapons in large quantities?"

Protector You said to Chu An with a smile: "The so-called decent families in the Central Plains, don't they hide piles of ironware in their own warehouses?"

So later they were all taken care of by the emperor. They mainly recalled that before the death of the original owner, the government almost confiscated all the iron tools of the famous and decent families, and they became deeply puzzled.

Is the government so tolerant towards the newly recaptured Western Regions?They were even allowed to buy ironware in large quantities?

Chu An looked at the proud expression of Guardian Right, and suppressed his doubts in his heart.

Perhaps this is a special treatment for the newly returned land?

However, after seeing the person in charge of the iron workshop, Chu An put his previous thoughts behind him.

This iron workshop was definitely sent by the emperor to fish!

Chu An looked at the person in charge of the iron-making factory who had become a magistrate five years later, and couldn't help shouting in his heart.

-------------------------------------

The original owner was quite impressed with this person in charge, and they happened to be participating in the martial arts conference under him at that time.

At that time, the martial arts conference had been held by the government. Although the finances were stretched every year, the emperor continued the tradition of the martial arts conference just to ensure that there were talents available in the army.

The first session was held in the capital, and the second session was in the hands of the magistrate.

Chu An originally wondered why the magistrate looked so young in the memory of the original owner, yet he took a high position. Now that he thought about it, he might not have been promoted in the Western Regions for so many years undercover to provide the emperor with a list of Western Regions powers.

The magistrate five years later is still just a small official in the iron workshop of the Western Regions. He received Chu An and the others cheerfully and asked them why they came this time.

"Brother Zhang, it's not me who made the decision this time, but our young master." Guardian Right introduced to Chu An with a smile, "Young master, this is Zhang Chen and Fangzhu Zhang."

Zhang Fangzhu really deserves to be a film king figure who has deceived the entire Western Regions. As soon as he turned his head, he saluted Chu An with a flattering face: "I don't know that the young master of the Lieyan Sect is here, and I am disappointed. I hope the young master will forgive me." indivual."

Then he got up, rubbed his hands at Chu An and said, "I don't know what kind of ironware the young master wants to order today? Swords, guns, axes, axes, hooks and forks, we can make all of them here."

Although Chu Anming knew that the film emperor was here to trick them, but the emperor had no plans to attack the Western Regions at the moment, so there was no need to worry about buying ironware before doing so.

So Chu An unceremoniously handed over the length of the steel bars he needed and the patterns on them to the actor in front of him.

The actor accepted the request with a flattering face, but after seeing the request clearly on the paper, he immediately froze on the spot.

Chu An looked suspiciously at the stiff expression on the actor's face, and asked suspiciously, "Master Zhang, can't this steel rod be made?"

He had inquired about it, and with the current level of steelmaking, it shouldn't be impossible to make some ordinary steel bars.

I saw the film star said with a smile that was uglier than crying: "Young master, I can do it, but the pattern and length you requested are really embarrassing for my old Zhang. After finishing your order, All the blacksmiths in my house will be exhausted."

It was only then that Chu An remembered that there were special machines to carve the patterns on the steel bars in modern times, but in this era, they could only be carved with one hammer at a time.

Chu An seemed to be stiff for a while, but in fact he poked the system in his head to ask whether there were patterned steel bars as support, whether it would have a big impact on the height of the floor.

The system was really speechless about Chu An's question.

"Host, are you going to build a building with more than 10 floors in this elevator-free era? Besides, with me here, the security issue you are most worried about, host, is just an inspection."

It was only then that Chu An suddenly realized that his requirements for steel bars were all for modern large buildings with 30 floors. However, in this era, let alone 7-story buildings, it is a matter of whether anyone with a building above [-] floors is willing to climb stairs every day.

After Zhang Chen received the news that he didn't need to tap the pattern as he wished, he asked with some doubts: "I don't know why the young master needs so many steel rods?"

'After Chu Xiaoxiao passed away, the Lieyan Sect had internal and external troubles, but what can these steel sticks do?Could it be that this young master is planning to expand the Lieyan Sect? Zhang Chen thought seriously while maintaining a flattering smile on his face.

And Chu An's words interrupted Zhang Chen's thoughts.

"Build a house."

Seeing Zhang Chen's stunned expression, Chu An repeated again.

"These steel rods are used to build houses."
