He called Tian Zong and Ou Yexia over and asked Zhang Yumeng to start explaining the functions and effects of cement. As expected, they were all shocked.

Yang Qian tilted his head. As expected, the three swordsmen Xia Xue and Qu were also there. Nima was just like Niubi Tang. He must not be a particularly high-ranking official. Otherwise, wouldn't he have to work here every day?

Ou Yexia was silent for a while and said, "General Yang, this thing is easy to operate. Just give it to the idle soldiers and let them do it. What do you want me to do?"

"I need iron bars." Yang Gan said.

"What do you need iron bars for?"

"Weave iron bars as thick as a finger into a frame and fill them with cement, so that they become extremely hard stone slabs."

"Then lay the stone slabs flat and stick them with cement, and wrap the current city wall inside. You can also pour cement into the gaps or rammed earth."

King Xia Wen couldn't help but interjected, "Is this thing really as good as you say?"

Zhang Yumeng jumped out directly, "I came up with this. It must be easy to use. Unfortunately, there are no shells here. If there are shells from the sea, smash them into powder and add them to the hardness."

King Xia Wen's eyes lit up and he glanced at Tian Zong. Tian Zong immediately suggested, "Actually, there are a lot of hay and shells in Tuncheng and Shoucheng. If you want them, you can get them by nightfall. There is quite a lot." "

When he heard that there were shells, Yang Gan was stunned and asked, "Lao Tian, ​​is there a sea here?"

"There is the sea a few hundred miles to the south. Over there is Haichao County. It relies on the sea to eat and has made a living by fishing for generations. Many people will bring shells and the like here. When building earthen walls, they use shells to grind them. The powder is also very easy to use." Tian Zong explained.

"That's not right. Isn't the South Shangguo?"

"Strictly speaking, the sea is southeast of Yuntong County."

"Okay, Zhang Yumeng, you can take charge of teaching these soldiers the things here. I also have 1,800 slaves from the country who were rescued from the Huns and have no place to arrange them. They can just work as coolies and provide enough food."

Yang Qian quickly implemented all the matters and let Tian Zong check the specific implementation. Zhang Yumeng began to direct the soldiers to start refining cement. Although she was working, she was still puzzled.

"How does Yang Gan have such a brain? How does he know about reinforced concrete and concrete, and how he knows so much about cement and cement plus shells?"

Suddenly, a flash of light flashed, and Zhang Yumeng opened her mouth in surprise. She was rescued by him and came to the Yang Mansion.

The toilet, bathtub, rain shower, washbasin and some furniture that did not match this era were seen inside, and there was no doubt about the cement itself.

A normal ancient person would definitely not believe in the effectiveness of his cement without seeing the real thing, but Yang Qian was indeed unswerving. The only explanation is that he knew this thing.

"Is he also a time traveler?"

But soon, Zhang Yumeng shook his head. No one in modern society would have such great ambition and courage.

And no matter who travels through time, it’s impossible to instantly hold weapons and go to war, right? How many modern people can do this?

He almost died in the execution ground when he came. Zhang Yumeng subconsciously believed that others should be the same as him. If Yang Gan is not a time traveler, then his ability to accept and draw inferences from one example is too strong.

After arranging the mission, Yang Gan began to inspect the ordnance, and sure enough he saw dozens of modified tanks, with ferocious bronze spiral blades emitting cold light in front of them.

No one would think that this thing is not sharp, and many soldiers even feel a chilling feeling every time they walk past the chariot.

Some soldiers exclaimed, "Fortunately, this chariot belongs to their own camp, otherwise when they set up the military formation, their legs would have been weak before the chariot came."

In addition to chariots, there are a lot of ordnance to be inspected. The equipment of the entire frontier army is in a mess. Some use bronze swords, others use iron swords, as well as armor.

Those who can serve as the main force all have their own armor and weapons. Many people's armors are even of the type from decades ago.

If the armor is well preserved, it needs to be maintained regularly. It is not a problem to pass it down to two or three generations. But if you just come by yourself and bring nothing, you can only serve as an auxiliary soldier, and you will most likely be sent as cannon fodder.

When he came to the city wall, Yang Gan jumped over and looked around. This place is composed of two majestic and majestic mountains, with mountain roads stretching for hundreds of thousands of kilometers next to them.

It's not that people won't come from other places, but the cavalry will definitely not be able to pass through the uneven and bumpy mountain roads, and they will have to give up most of their baggage.

Can the Huns still bite people without their cavalry?

How many days can the dry food you carry with you last? Let’s not talk about other countries in the Central Plains. Just the consumption alone can kill the Huns.

Baiyunguan Pass is an irregular rectangle, made of long, round, flat and rammed stones. The east wall is 800 feet long, the west wall is 600 feet long, and the south wall is more than 80 feet long.

There is also the Dongmen Guanlou in the east. It is 31 feet long from north to south and ninety-three feet high. It is concave in shape and runs from west to east. It controls the main entrance to the pass. The Guanlou is a three-story mountaintop-style building with double doors and double buildings. , each roof is decorated with a red phoenix, so it is also called "Danfeng Tower".

Located at the lower end of the city wall on the right side of the east gate of the building, there is a shaft-type weapons warehouse. The arrow warehouse is like a dry well, and there are bundles of arrows in it, about 1 cubic meter.

Looking around, the sky is blue, the fields are vast, and the wind-swept grassland has no cattle or sheep in sight, only the slightest look of desolation.

A few days later, Fujiko Jin arrived at the reception camp of the Jie tribe. This was the only way for the Xia Kingdom's caravans to pass. The roads were opened according to the needs of each tribe, and the goods inside the horses were also inspected.

Fujiko Jin threw some tea bags skillfully. In the grassland, the attraction of money is far less attractive than material.

The tea that can be sold here is a luxury product. Only nobles can use it, and ordinary people can save it.

Some people are already very fragrant when they drink milk. Tea leaves can only be picked up and bitten when the aristocratic grandfather throws away the tea leaves.

"Hahahaha, my Brother Teng, come and pull me." A big fat man wearing gold and silver came out of the tent to welcome him.

The current Fujiko Jin is good news for him. When other merchants come, they just bring some salt, tea, and silk. If it were normal times, it would be really valuable, but now the Huns have been attacking the Jie tribe fiercely.

The Jie tribe is also considered a large tribe on the grassland, but unfortunately they are still unable to cope with the powerful Huns. Apart from the initial tug-of-war, now they are simply being suppressed and are in urgent need of copper and iron.

Fujiko Jin was one of the very few merchants in Daxia who could provide copper and iron, so he was naturally treated with great courtesy.

"Hahaha, Mr. Wanhu, long time no see." Fujiko Jin said with joy on his face and held his hands towards the other party.

The two of them started to talk to each other in a cowardly manner and walked towards the big tent.

The head of Wanhu asked his servants to serve butter tea and said, "Brother Teng, I have something to say directly. The Huns' offensive is getting more and more fierce. They seem to be going crazy during this time. We, the Jie tribe, did not offend them."

Fujiko Jin nodded, "Copper, iron, salt, I also specially prepared some good things for the heads of ten thousand households."

A sly smile appeared on Fujiko Jin's face, and the head of the household touched his rough beard and smiled.

After counting the supplies, it was already nighttime. Inside the camp, the head of the household was flushed, his eyes were bloodshot, and sweat was forming on his forehead.

"Okay, okay, this Five Stone Powder is really good. After eating it, my whole strength becomes stronger."

Wan Huzhang is a bit ecstatic, but judging from the cold light emanating from the faint triangular eyes, he is not a simple person.

After giving his subordinates a look, a large group of centurions and centurions below began to toast Fujiko Jin enthusiastically.

"Ah, that's enough, that's enough. I don't drink much."

All the Jie people were so enthusiastic that they almost grabbed Fujiko Jin and drank wine. After a while, his whole face turned red.

The Jiangjun Lie produced in Zhuangzi is no joke. Many Jie people like to drink Jiangjun Lie mixed with kumiss. Firstly, it has a milky flavor, and secondly, it can increase the alcohol content.

Wanhu Zhang looked at his subordinates, and the captain immediately understood. He pulled Teng Zijin and said with a smile, "Brother Teng, the good thing you mentioned is the Five Stone Powder?"

Fujiko Jin blushed, waved his hands wildly, and muttered, "Hahaha, I originally prepared things for you, but you don't need them anymore."

Suddenly everyone became interested, and the captain asked, "What good thing is it? We don't have much money, but we have enough cattle, sheep and horses. If you have any good things, just take them out."

"Oh my gosh~~~~That's tens of thousands of swords, ready-made, equipped and ready to go on the battlefield."

Everyone present was dumbfounded. They didn't offer such a good thing. The Xia people were really cunning and they must have wanted to raise the price.

Wan Huzhang's face darkened, "Brother Teng, we Jie tribesmen treat you as a brother, but you treat us like Weiwei. Why don't you bring out such a good thing?"

Fujiko Jin shook his head and said with a smile, "These weapons were originally planned to be sold for a good price. Who would have thought that when I came here a few days ago, I met a caravan coming from the King's Court of Shanshan. There was a friend among them. He told me

.....Hiccup~~~"

Seeing Fujiko Jin's shaky appearance, not only the heads of households but also the commanders and centurions below became anxious, half-said, "I won't have a wife in the future."

Teng Zijin rubbed his chest, his face was very ugly, and after burping, he said, "Eighteen tribes of the Xiongnu were wiped out. The Chanyu was furious and asked his son, King Zuo Xian, to gather troops to attack the Xia Kingdom."

"Since the Huns are about to retreat, you probably won't be able to use these weapons. It's a pity that I have been transported over a long distance, but there is no place to use them." After finishing speaking, Fujiko Jin fell down on the carpet.

Woke up soundly and sound asleep.

With a "pop" sound, the head of the household stood up, his triangular eyes looking left and right, and after a long time, he sat down heavily in his seat.
