Now that the war is gradually subsiding, Jiang Song naturally does not have to be as busy with the border as before.

Usually just training soldiers in the military camp outside Beiping City, and at this moment they just returned to the palace. Luo Cheng came to the door with two sharp swords, although Luo Yi said that the emperor was imminent, but their brother's relationship was not much indifferent.

But Jiang Song was still a little surprised when he saw Luo Cheng, after all, he knew that Luo Cheng had been busy recently and had little free time. At this moment, he deliberately came back to find him, presumably there must be something.

"What is the second brother looking for me, is it because your wooden ox and flowing horse have already achieved new results?" Jiang Song thought about it, and asked with some curiosity, he was also a little interested in the steam engine.

Hearing this, Luo Cheng chuckled and shook his head, and said: "Although the wooden cow and the horse have other achievements, I don't need to personally come to inform the eldest brother, Luo Cheng came today to give the eldest brother a sword."

"Send a sword?" Jiang Song was slightly stunned, and he didn't react, for no reason, what did Luo Cheng do when he gave him a sword. But Jiang Song obviously knew Luo Cheng well, and did not ask questions.

Luo Cheng took out the two swords on his body, handed them to Jiang Song and said, "These two matching swords are made of steel, and the steel of the sword is made by me."

Jiang Song suddenly realized, it turned out that there was still this meaning in it, and he didn't think much about it, he just took a long sword and pulled it out, and the cold light flashed, making Jiang Song's face change slightly.

Jiang Song's surprise was expected by Luo Cheng, because the long sword forged by Xingang was countless times sharper and stronger than what was commonly seen, as if it was a rare sword today.

Although Jiang Song had seen such a divine weapon, he heard that this sword was actually made of new steel practiced by Luo Cheng, how could he not react at all. Such a sharp weapon is truly extraordinary.

"This steel is actually cast by a new method, and it is rare for a weapon to be so sharp." Jiang Song sighed with heartfelt emotion, holding the long sword in his hand, with an inexplicable feeling.

After all, this sword was forged by Luo Cheng, and it was very different from the feeling of ordinary sword. It was waved away, and a cold light appeared in the air, and a cold front also came out.

Seeing that Jiang Song liked this sword, Luo Cheng was naturally happy, so he smiled and said: "How about this sword, big brother still likes it, the new steel cast sword, only these two are owned by you and my brother."

Hearing Luo Cheng's words, Jiang Song couldn't help but be silent, of course he knew what the deep meaning was. The two brothers, although they are double swords, are a family, which is the friendship between their brothers.

So Jiang Song turned around and looked at Luo Cheng, and said angrily: "This sword is given by the second brother, how can I not like it for my brother, I will use this sword to kill all foreign enemies in the future and raise the prestige of our country."

Jiang Song was not ambiguous at all, his words undoubtedly aroused Luo Cheng's interest, and he also said: "Today, with this sword as proof, you and my brothers will work together and never lose each other."

The two looked at each other and smiled, both feeling happy.

……

After giving the sword, Luo Cheng returned to the workshop again.

The method of steelmaking has already worked, and Luo Cheng is to order the craftsman to continue refining, and the follow-up promotion method will be discussed after the situation is stable. Steel was drilled here, and it was used for wooden oxen and horses.

In addition, the cement arranged by Luo Cheng also came to fruition, and under the guidance of the craftsmen's efforts and Luo Cheng's drawings, they finally succeeded in firing a batch of cement.

Upon learning of this, Luo Cheng rushed over.

This is the advantage of the superior, although Luo Cheng has arranged many projects, he does not need to spend too much energy, as long as he guides the craftsman step by step.

Soon, Luo Cheng came to the cement workshop, and when he saw the familiar gray powder, he couldn't help but nod. But it is still not certain whether the cement is successful or not, and it will have to be experimented.

Luo Cheng pounded the cement according to the future process, and then put it aside to dry. According to Luo Cheng's estimate, it will be able to dry in one day at most.

The experiment that Luo Cheng has to do is how hard the cement is after solidification, and whether it can meet Luo Cheng's requirements. However, according to Luo Cheng's view, there is still a good chance.

Time flies, and in the blink of an eye, it is a day.

Luo Cheng took the craftsman again, looked at the cement that had completely solidified and dried, and began to pick up the hammer and beat it. Luo Cheng's strength is too huge to be compared to ordinary people, so naturally it can't be used as an experiment.

Therefore, a craftsman spent a lot of effort and finally hammered down the cement wall that Luo Cheng had built. When he gasped, his face was also happy, and in his personal experience, the cement was undoubtedly a success.

All the craftsmen present also showed different colors, and they naturally knew that the man did not release the water. If that's the case, then the effectiveness of this cement is somewhat amazing.

The normal city wall is several meters thick alone, and it is naturally impossible to break it with an iron hammer. But there are a lot of things that are added, the cost is extremely high, and most importantly, the time it takes is just as long.

But this cement is different, and this thin wall alone can withstand such a heavy blow. If you increase it several times, I am afraid that it will be comparable to the strength of the city wall.

Although the development of cement has been full of twists and turns, everyone present knows that its cost is nothing but Erer, and it is nothing at all. At a lower cost, but with considerable quality, you can see at a glance who wins and who loses.

The most important thing is obviously not this, because the concrete wall has been formed in just one day. If it is used to build city fortifications, it should not be too fast.

Everyone looked at each other and began to understand what they were doing, but it was ridiculous that they had doubted Luo Cheng's intentions before. At this moment, the results appeared, and they could no longer question them.

Luo Cheng is still very satisfied with the effect of cement, and it seems that his infrastructure construction has finally been settled. However, this production alone is not enough, and we must find a way to expand it.

At this moment, cement can also be regarded as a strategic resource, and Luo Cheng naturally can't easily leak it. He directly issued a gag order, and if anyone dared to divulge the method of cement manufacturing, he would be killing himself.

After that, Luo Cheng went to Hu's father again and ordered him to build a few more workshops. Although it is not yet time for a large-scale expansion of Beiping City, it is always okay to prepare in advance.

This was Luo Cheng's order, and Father Hu readily agreed, he had already made such preparations. Now as long as you follow Luo Cheng's order, you will definitely not suffer, if you disobey Luo Cheng's order, you really don't know whether you live or die.

Hu's father was extremely efficient, and soon recruited a group of craftsmen, and at the same time built several workshops outside the city of Beiping. Luo Cheng found reliable people from the original workshop and distributed them everywhere.

Several workshops started working together, and the output naturally went up.
