Chapter 399

Su Ling kept her concubine identity and didn't want to appear in public with Chen Li at the same time, so she went back to Tianji cliff first.

Chen Hai took the cheeky Qi Hanjiang to the bamboo hall, the meeting place of the school Palace at juquanling Zhongfeng.

The craftsmen and apprentices who hurried back and forth saw Chen Hai bow his head and salute one after another, and Chen Hai nodded one by one.

Zhang Xiong, Zhao Ruhui, Guo Hongxuan, Xue Cun and others knew at this time that Qi Hanjiang was not playing tricks, but Chen Hai rushed back to the Tianji school palace in his busy schedule and welcomed him into the conference hall of the bamboo hall.

By chance, Zhang Xiong, Zhao Ruhui, Guo Hongzhi and others are also gathering in the bamboo hall to discuss things.

Unlike other sects or sects, which sit after the long cases, the bamboo hall adopts a round table system. The Tianji craftsmen who are qualified to enter the hall and discuss the highest level affairs of the school palace discuss things around an oval long table.

Looking at the furnishings in the side hall, Chen Hai thought maliciously that if these old men in Taoist robes put on suits or white coats, wouldn't they be the same as the earth?

Thinking of the earth, Chen Hai was dejected. I'm afraid he won't have a chance to return to his hometown in this life.

He took a seat at random and asked Zhao Ruhui, "master Zhao, what are you discussing today?"

Apart from Zhang Xiong, the culprit of the Western Qiang rebellion, who was sent to Liquan with twenty or thirty thousand people by Chen Hailiu, Zhao Ruhui and others joined the Tianji school palace. They did not have any obligation to Longxiang camp and Chen Haixiao. However, resisting the invasion of barbarians is the main righteousness and is the duty of everyone. Zhao Ruhui and others gathered again today to discuss how to do their best, Support the construction of yuchengling defense line.

Chen Hai nodded slightly when Zhang Xiong and Zhao Ruhui said what they had discussed before. Many work were advancing in an orderly way according to their expected direction, saying:

"The demon barbarian army began to shrink to the north, and the defense war this winter is coming to an end, but the front line of yuchengling is far from stable, and the pressure of follow-up construction is even greater. The import of young labor has been negotiated with Tianshui county a few days ago. Zhou, Wu, Qu and other ethnic groups will no longer stop the landless poor households and move north to yandangyuan to find a livelihood. It is estimated that nearly 200000 people will move to the middle reaches of Guanhe River this year However, with a large number of sophisticated tools and common materials, Hengshan needs two or three years to build many workshops, and it still needs to be transported from Lequan in the early stage. However, at present, the transport capacity of the three wind flame airships is too limited, they are continuously used, and the pressure of maintenance is also very great -- a more important problem is that Yandang, as a flat plain, is full of lakes and rivers, Even if there are minerals underground, they cannot be mined. A large amount of copper and iron ore needed for building the city can only be mined from the deep mountains at the Western foot of Qintong, but transportation is a big trouble... Do you have any better ideas? "

Quenched gold and iron in Qintong mountain are very rare. There are many ordinary iron and copper mines. Tianji palace has long found more than ten large copper and iron ore veins in the West foot, but the biggest difficulty is to transport a large amount of copper and iron ore from the deep mountain in the West foot of Qintong every year.

The transport capacity limit of the three wind flame airships is 600000 kg. In addition, the main components such as airbags, dragon bones, davits and wind flame steam boxes need regular maintenance, repair and replacement. The ultimate transport capacity in a year is 100 million kg.

At the same time, the loading and unloading of copper and iron ore to the wind flame airship is quite inconvenient.

Previously, for the needs of the war, Chen Hai gathered tens of thousands of young workers in the Xilu mine to provide services for the mining, loading and unloading of copper and iron ore, barely maintaining this, but this is extremely uneconomical.

Previously built Tongkou City, only 35000 troops and horses were considered to be stationed, and the wall was only built to a height of three meters; In the future, the real Tongkou city should consider resisting the invasion of blood demons, and can accommodate hundreds of thousands or even hundreds of thousands of people nearby. On the one hand, the area of the city is expanding on a considerable basis, and the height of the city wall needs to reach 20 meters or even higher.

At this time, we also want to melt iron to build a city, and in the future, we will build ten main cities along the line of yuchengling. The copper and iron ore consumed is far from the concept of 100 million or 200 million kilograms.

After a lot of discussion, some people suggested that in addition to the three wind flame airships already under construction, more wind flame airships should be rebuilt. Some people suggested that a plank road should be built near the cliff and steep wall of Qintong mountain. Others suggested that the Tonghe River should be used to transport the water in the deep mountains at the Western foot of Qintong mountain.

Each proposal has limitations.

The repair speed of the wind flame airship cannot be fast, and the repair cost after it is put into use is not low. Not to mention the others, if an airship is used so frequently, the airbag needs to be replaced once a year, which requires two or three thousand pieces of top-grade animal skins; Even if there are ten wind flame airships, they are far from meeting the needs of transportation capacity.

The construction of the plank road is to drill holes in the steep wall of the cliff, insert beams and columns, and then lay bamboo and wood section by section. However, the width of the plank road is limited, and it is easy for a carriage to pass one way at the top of the sky. Moreover, it is not a thing that can be completed in a year to build a thousand mile plank road from Lequan to Hengshan, and the final transportation capacity is far from meeting the requirements.

It is true that Tonghe river connects Liquan with Hengshan and Tongkou, but Tonghe river passes through the deep mountains and mountains at the Western foot of Qintong, with a height of 3000 meters. The beach is urgent and dangerous. The whole river also forms a waterfall like discharge, which makes it difficult for boats to pass.

Otherwise, the current land and water channel has long been formed from Hengshan to Tongbei mansion, and there is no need to wait until now.

However, when it comes to the transportation of bulk materials, the use of river is undoubtedly the most convenient and economical.

"Cough!" Chen Hai coughed twice and interrupted the discussion. With a wave of his hand, the topographic map of more than a thousand miles from Tianji learning palace to yandangyuan slowly appeared in a light curtain.

"It's too expensive to transport iron ore by wind flame airships. Even if there are ten or even twenty airships, they can't transport billions of kilograms of iron ore out of qintongshan every year, not to mention there are too many places where wind flame airships are needed. It's not impossible to build a plank road, but it needs to invest a lot of manpower and material resources in the early stage, and the transportation capacity in the future is limited - this thing needs to be done, but it can only be done slowly Even if we succeed in building an access road connecting Hengshan Mountain in five years, we still need to focus on the Tonghe River in the early stage. The Tonghe river winds out from the eastern foot of Qintong mountain and goes West through Liquan. After leaving Qintong mountain, it goes north and goes to the vast sea. There are countless streams, rivers and lakes in Qintong mountain, which can connect various mining sites with the Tonghe River, and we even know it You can cultivate more fields in the deep mountains at the West foot... "

In addition to Zhou Jun, Wu Meng, Cao Shan and other ethnic groups, Chen Hai also accepted refugees and prisoners of war in juquanling in his early years, and more than 20000 criminal families of the Zhang family moved into Liquan in his later years. The population of Liquan has long been 300000.

There are many mountains and few fields in Liquan. It is also a pity that in addition to the Tianji learning palace, the valves can accommodate such a large population in the Liquan building workshop.

Of course, in order to relieve the pressure of land and food, Chen Hai also looked for relatively open valleys and flat dams, built villages and moved some landless poor people into the deep mountains to the west of Juquan ridge and almost on both sides of Tong River.

At the same time, there are also some aboriginal villages in the deep mountains. There are hundreds of thousands of mountain people who inhabit and reproduce and live an isolated life.

At present, only by connecting the river channel of Tonghe River and forming an extremely rare waterway channel between Hengshan and Liquan, it is not difficult to transport the minerals in the deep mountains at the Western foot of Qintong, but in balance, the quantities are much more difficult than building a simple plank road.

It's impossible to do it in five years.

"It's impossible to completely connect the river, but it's not too difficult to transport copper and iron ore downstream in one direction," Chen Hai said, "There are four main superimposed flows at the West foot of Tonghe river. For example, when Juquan lake goes West, more than 100 high cliffs fall directly. However, we set up a transfer station at the top of the cliff to transport hundreds of millions of iron and copper from the top of the cliff, which is much easier than from the bottom of the cliff. We even need to build a slide to dump iron ore next to the stone cliff..."

If you think about it, it is much easier to concentrate millions of kilograms of copper and iron ore in front of the cliff and dump it directly under the 100m Cliff than transport it to the 100m Cliff

Transportation is one thing. At the same time, how much manpower and material resources need to be invested to mine such a huge amount of copper and iron ore in the hinterland of qintongshan every year?

Everyone frowned at the thought.

Hengshan and Tongkou are short of manpower. Can 200000 young workers be drawn out to mine in the mountain?

Chen Hai had thought about this for a long time. The mechanism puppet technique should be learned for practical use. If he had to dig minerals with a hammer and pick at this time, he would be famous as the Tianji learning palace. He took out a stack of pictures from the storage ring and handed them to Zhang Xiong, Zhao Ruhui, etc.

Zhang Xiong and Zhao Ruhui are dazzled and confused by more than a dozen kinds of drawings and conceptual drawings, such as rolling edge mining vehicle drawings and rail transportation drawings. In particular, the rolling edge mining vehicle actually installs mining parts at the front end of the crown block, which can also be driven by the wind and flame power box.

Of course, when Zhang Xiong, Zhao Ruhui, Guo Hongchen and others saw the picture of the mining vehicle, they all thought that if the mining parts were replaced with spiral blades, would all the traditional dense formations, including the spear heavy armor array created by Chen Hai, be destroyed?

At this time, I thought that I was not wronged at all when I lost outside Yuchi city.

Zhang Xiong, Zhao Ruhui and others were immediately confused. I believe Chen Hai could never have thought of this. Once Longxiang camp was equipped with such a rolling blade chariot, used with a heavy bore crossbow, and poorly equipped demon and barbarian soldiers, how could it resist? Do they still need to spend so much effort to build a city by melting iron on the front line of yuchengling?

Chen Haifei made such great efforts to build a city by melting iron in Yucheng ridge. Is it really demon and barbarian soldiers to guard against?

Of course, Chen Hai didn't say. Zhang Xiong, Zhao Ruhui and Guo Hongzhi didn't think about it. They just asked, "is this mining car to be secretly manufactured?"

Chen Hai nodded and believed that Zhang Xiong and they had also learned the great value of the mining vehicle structure. They asked Zhao Ruhui to specially supervise the manufacturing of mining vehicles, and then left Zhang Xiong to speak alone.

After Zhang's defeat in Yuchi City, more than 20000 people were put into Liquan with Zhang Xiong by Chen Hailiu. However, Liquan is too narrow. Most of Zhang's people can't even share the cultivated land to support their families. Most people are arranged to work in many workshops. Don't expect to restore their previous life of rich clothes and food at all.

Chen Hai wants to move some of Zhang's people to Hengshan and Tongkou this time, so that most of Zhang's people can be separated and take root in yandangyuan.

In terms of a high-quality population, Chen Hai has only 20000 disciples of the Zhang family. After years of polishing and training, they should be able to be of great use after honing their lightness, arrogance and disdain for the bottom.

Zhang Xiong also knew that this was a good opportunity for Zhang's rise again in Yanzhou and a real rise. Naturally, he would not refuse to agree. He knelt down in front of Chen Hai and shouted, "everything is at the Lord's command!" he was really willing to vote in front of Chen Hai.

"Zhang Gong doesn't need to be polite. Things are difficult. We just support each other." Chen Hai helped Zhang Xiong up and said.

Worried about the repetition of the blood cloud wasteland, Chen Hai went back to Tianji cliff to find a clean room, urged the Snake Bracelet, and then sneaked into the blood cloud wasteland again.
