"Take me to see it." Huo Gang nodded and said, according to the spirit of the Jade Gate, there is less than a week left for the formation of the river, and if you want to dig the river channel and build a long enough river, then the time is still quite tight.

"General, please come with me." Yang Lao Wu immediately spoke.

Turned over and followed Yang Lao Wu Huo Gang to the top to investigate the terrain, according to the source of the river chosen by Huo Gang, it is in the Qilian Mountains next to it, and the location where it can flow out, Huo Gang can be determined now, because there is only one valley here that stretches out from the mountain range.

At that time, the river will definitely flow out of this valley, and the depression that Yang Lao Wu and they chose is actually at the exit of this valley, Huo Gang and they stood at a high altitude and observed, the area of this depression is very large, it is estimated that it is at least close to twenty kilometers from north to south, and it may be longer from east to west, but to the east, the mountain range where Yangguan is located on the east side and the Qilian Mountain are gradually beginning to merge.

Although it is still lower than the mountains on both sides, it is much higher than the terrain to the west, so you don't have to worry about water flowing out of that side.

"A few of you looked at it here, and they probably estimated that the lowest place in the middle of this depression, the highest place on our west side is about 10-15 meters lower, and after the natural embankment on the west side, the terrain starts to extend downward, and if we dig there in advance, the river can only flow out of that place."

"And from the natural embankment, the terrain is relatively gentle for a distance, so in order to concentrate the impact of the water flow, it is best for us to excavate in that place, bind the river in advance, and set aside a section of 4,000 meters of river channel for our later use." Yang Lao Wu said quickly.

"Your time is very tight, I think it's too late, especially the river on both sides If you want to use cement to build, I'm afraid the cement fired during this time is not enough, right?" Huo Gang asked.

"It should be enough, Wang Luo and Tian Zhong have discussed, considering the impact of the water flow in the construction of the embankment, the muddy concrete made by the general before is not too practical, but the cement can be used as a binder, and then the stone is used as a brick, similar to the way of stacking the city wall, so that the embankment uses a large number of large stones and cement for bonding, and the amount of cement used for the embankment will not be too much."

"As for the excavation of the river embankment, it may be necessary for you to order the general to mobilize these herdsmen from the Tongluo tribe. For 10,000 people, five days is enough to dig out this section of the river, which is also our lack of tools, otherwise, this time should be shorter. ”

"During this time, I went to Akcheng to buy a lot of iron tools and came back, and Lu Feng and everyone have made these iron tools into iron picks and shovels." Yang Lao Wu said quickly.

"I can give an order, but you have to think about one thing in advance, and that is the bridge." Huo Gang thought about it, but still reminded him.

"Speaking of which, General, I'll have to introduce you to someone." Yang Lao Wu said with a smile.

"Oh?" Huo Ganghuan looked at Yang Lao Wu with interest.

"His name is Zheng Feng, his name is high, he is a bridge expert, and his teacher is a famous bridge master of the former Sui Dynasty, Li Chun." Yang Lao Wu said with a smile.

"Who do you say his teacher is?" Huo Gang was stunned for a moment, and couldn't help but ask.

"Li Chun, does the general know about Li Chun?" Yang Lao Wu looked at Huo Gang with some surprise.

"Did Li Chun preside over the construction of an arch bridge called Zhaozhou Bridge? What do locals call the Big Stone Bridge? Huo Gang immediately asked.

"The general really knew, but he didn't expect the general to know the names of Li Chun's family. The general is really wise, his teacher is Li Chun, who built the big stone bridge, Zheng Feng has already won the true inheritance of his teacher, but what he has learned in this Western Regions is almost useless, he originally thought that his life would be wasted, but he didn't expect the general to give him the opportunity to show his ambitions. Yang Lao Wu immediately arched his hand.

Huo Gang couldn't help but take a deep breath, this Anno ...... What a good person, many people don't know about Li Chunqi, but Zhaozhouqiao is afraid that Huo Gang knew it as long as he went to school in that era.

After 1400 years of wind and rain can still exist, it is conceivable that the design of Zhaozhou Bridge is absolutely leading the world, even in modern times, the design of Zhaozhou Bridge is probably not too backward.

And the personal disciple of such a person is actually in Anno's tribe, Huo Gang now suspects that those people in Anno's tribe will not everyone have a few brushes.

"Is Zheng Feng in the industrial zone now?" Huo Gang immediately asked.

"Yes, he has discussed with a few people before, it doesn't matter if the bridge can't be completed now, he said that the cement invented by the general will make the construction of the bridge easier and faster, and now we only need to flow out of a large enough area on both sides of the river in the early stage, and use concrete to lay a large enough area and a strong enough foundation, and it will be easy to reproduce the big stone bridge built by his teacher in the future." Yang Lao Wu immediately spoke.

"It's simple, if it's just a foundation, as long as the pit is dug deeper, and then the area is larger, and the concrete can be poured directly." Huo Gang nodded.

He also thought about designing the bridge himself, if Huo Gang designed it, he really didn't know how to design, bridge design really needs experts, although a modern person knows that the arch bridge has advantages, but how to design the arch is also to be calculated.

Huo Gang didn't know this, but Huo Gang's original idea was to play with the miracle of flying bricks like Lao Maozi.

It's very simple, dig a channel directly next to the river, and first divert the river from the side to bypass it.

Then in the place where the bridge is going to be built, it is a big deal to build a few more reinforced concrete piers in the middle, and the bridge will not be arched, but does the reinforced concrete need to be arched? If you have more piers, just use wood to erect them and then pour the concrete bridge deck.

As long as the material is strong enough, it doesn't matter if it meets the mechanics or not, Huo Gang is not ready to let it be used for thousands of years, as long as it can support it for decades, he doesn't believe that he can't train an expert in bridges for decades.

Now it's good, just send him an expert in bridges, and now the advantages of reinforced concrete are needless to say.

"Let's go, let's go back now, I'll go directly to Amatuo, you call Zheng Feng over, and let all the Tongluo tribes move." Huo Gang said very simply.

"Yes!"

Now that the decision was made, Huo Gang did not hesitate, and followed Yang Lao Wu back to the industrial area directly, and Yang Lao Wu quickly gathered these craftsmen.

Huo Gang also met Zheng Feng, Zheng Feng looks very old, mainly because he looks old, but Huo Gang has already known Zheng Feng's age through Yang Lao Wu, he is forty-seven years old this year, Zheng Feng has been following Li Chun since he was five years old, and it can be said that he has learned the true biography of Li Chun.

"I've seen the general." After Zheng Feng saw Huo Gang, he hurriedly bent down to salute Huo Gang.

"Zheng, you're welcome, I just heard from Yang Lao Wu that you have already designed the plan for the bridge." Huo Gang said.

"Yes, General, I have been testing the strength of concrete made of cement these days, and in a way, it is even harder than some natural stones, because it can directly form a whole so that the forces acting on it are not dispersed."

"In addition, I heard the general say that if you can add steel bars to the middle of this concrete, if you turn it into reinforced concrete, it will become stronger, and in this case, it will not be a problem for our bridges, but we have too little steel now, although it is okay to use steel, but the quality may be worse." Zheng Feng immediately said with some excitement.

He originally thought that what he had learned could only be buried in a coffin, but he didn't expect that there would be a chance to build a bridge in the Western Regions, could this not make him excited?

"Well, it's simple, build a spare, steelless concrete bridge in the early stage, and then build the main bridge through it later." Huo Gang said very simply.

"Yes." When Zheng Feng heard this, he was immediately overjoyed, as a bridge expert, his greatest wish in this life is naturally to build bridges.

After confirming with Sun Er next to them, Huo Gang also took direct action, as for these Turkic herdsmen, for the time being, let them see the operation of these cellar furnaces, it is indeed possible to leak secrets, but Huo Gang is not worried.

First of all, these Turks are illiterate, not to mention ordinary Turks, even the literacy rate of those Turkic nobles is not very high, and most of the Turkic nobles only know a small part of the script.

Secondly, after the river appeared here, these Turks would never leak any news here, because at that time, Huo Gang was the god in their hearts!

Huo Gang, who came here from later generations, couldn't be clearer about the power of faith, and after more than a thousand years, faith has such terrifying power, let alone this era of ignorance.

What's more, these Turks were doing hard work, and the work at the heart of these factories was now carried out by the Anno tribe.

After finding Amato, Huo Gang directly conveyed his orders to Amatuo, and soon, the 10,000 Turks who had migrated here to the main headquarters of the Tongluo tribe began to act one after another.

With the exception of children and the elderly, even all the women began to work, and the work of herding cattle was temporarily handed over to the elderly and children.

For these herders, there is no problem at all with the elderly and children grazing, and more than a thousand years later, the herdsmen and children of Inner Mongolia can ride horses and gallop at the age of five or six, let alone this era.

With the addition of seven or eight thousand strong laborers in the entire industrial area, the entire Gobi Desert instantly began to become in full swing, such a scene, the last time it appeared was Huo Gang in his previous life when he was a child, he built roads when he was a child, and everyone from a dozen nearby villages contributed to the collective construction, until the country had money, and it was gradually handed over to professional construction workers and machinery.
