From Propulsion City To Multiverse

Just as the Kunpeng airship swaggered all the way to Yangzhou City.

Many projects in the territory of the Human Revolutionary Federation are also gradually bearing fruit.

As the Pearl River (Xijiang) - Yangtze River (Xiangjiang) canal, namely Lingqu.

This canal has been tenaciously functioning since it was built in the Qin Dynasty. However, due to the shallowness and narrowness of the river and the terrain constraints, only flat-bottomed boats with a displacement of less than 10 tons can pass, which greatly limits the value of the canal. .

In order to transform the canal, Tang Feilin personally presided over the transformation plan.

At this time, the water near Lingqu has been completely cut off.

Tang Feilin simply asked the more than 20,000 people in the two nearby counties to stop agricultural production, and all food was supplied by the government. Together with 3,000 professional engineers, they all invested in the Lingqu reconstruction project.

Hundreds of tons of explosives almost flattened most of the stones in the ancient river.

In addition, Tang Feilin also built a reservoir. With the arrival of spring, the continuous rainfall caused the water volume of the reservoir to rise to the warning level.

Tang Feilin watched as the water level in the core river was also rising. Until March 13, the secretary in charge of monitoring the water level ran over with cold sweat on his forehead:

Tang Bu, the south embankment has broken.

En! Continue to monitor and ensure that the direction of water impact is in the predetermined direction. Tang Feilin was very calm.

clear.

The section of the Ling Canal that connects to the Xijiang River is already in a mess at this time. The flood from the upper reaches, guided by the guiding channel, is eroding the river crazily.

The big rocks in the river have been blown away, and many trees and vegetation on both sides have been cleaned up in advance, and even plowed with an iron plow to artificially cause soil erosion.

Under the impact of floods, the river channel is constantly expanding and deepening.

The existence of the flood channel is not set up randomly, but through geological exploration in advance, and the stratum without too many rocks is specially selected.

The downstream villages had been notified in advance to evacuate, Tang Feilin would not joke about human lives, and at this time the population of Xijiang was not dense, not as overcrowded as in later generations.

Artificial water storage, destruction of vegetation along the way, destruction of rock formations where they must pass, digging guide channels,

It is to take advantage of the torrential rain in spring to create large-scale soil erosion and wash out a large river.

Although the life and production of more than 100,000 people along the route will be affected to a certain extent, the NRU has the confidence to compensate them.

The torrential rain continued.

It wasn't until two days later that the raindrops became slightly smaller.

Tang Feilin immediately ordered: Second interception.

Yes.

On a reinforced concrete dam that had been built in advance, following Tang Feilin's order, the engineers and militiamen who had already been prepared quickly pushed the iron cages full of big stones into the gap one by one.

Then there are a large number of sacks filled with sand, which are also constantly pushed into the gap of the dam.

After more than five hours, the gap in the dam was firmly blocked, and the engineers and militiamen continued to reinforce the gap after lunch.

According to the estimates of the Ministry of Weather, there will be at least two to three days of rain in the clouds over the Xijiang River Basin.

As time went by, the amount of water stored in the Lingqu temporary reservoir increased rapidly.

Two days later, when the water level approached the warning line again, Tang Feilin ordered to dig the dam on the north side to allow the flood to hit the river on the side of the Xiangjiang River.

Still the same recipe.

Crazy floods quickly transformed the upper reaches of the Xiangjiang River.

At this time, Tang Feilin took people to inspect the upper reaches of the Xijiang River.

The river is still flooding, but the scale is much smaller. After all, there is no human guidance, and the large amount of precipitation accumulated in the reservoir has destroyed vegetation and rock formations. The river will not be so violent.

The river channel, which was originally only a dozen meters wide, has now been expanded to about 30 to 40 meters, and the depth has also reached 3 to 4 meters.

Of course, this is the flood thought data.

Tang Feilin estimates that after the river subsides, the width of the upper reaches of the Xijiang River will remain at about 20-30 meters, and the depth will be about 1.8-3 meters.

Moreover, the water level difference between the upper reaches and the middle reaches will be further reduced.

After the second refinement, the transportation carrying capacity of the Lingqu Canal will be greatly improved.

According to Tang Feilin's estimation, in summer when there is abundant precipitation, the largest ship passing through the Lingqu Canal is a flat-bottomed cement ship with a displacement of less than 500 tons.

And in the winter season when the flow is reduced, the water level of the river can also be adjusted through the reservoir to maintain the traffic conditions with a displacement of less than 200 tons.

Compared with the previous small wooden boats of less than 10 tons, the traffic capacity has increased by 20 to 50 times.

Moreover, this method of using water to build rivers can be used continuously, but in the future, the canal can only be temporarily closed when there is a heavy rain, and the canal will be gradually deepened and widened.

If this method is used for a long time, it may even divert the Yangtze River to the Pearl River, so a certain degree must be grasped.

The reason why later generations do not use this method is because of the dense population on both sides of the river, and man-made floods and soil erosion. A bad one is not a matter of losing the black hat, but a loss of life.

But now the population in the south is small, and the migration of the population along the river is also convenient.

Of course, this solution is only suitable for rivers in mountainous areas. Although it can be used for rivers in plain areas, the effect will be weakened a lot.

After all, it is easy to build reservoirs in mountainous areas, and it has the blessing of gravitational potential energy.

A day later, the surrounding area of ​​Lingqu began to clear up.

The river flushing project in the upper reaches of the Xiangjiang River was almost half completed, and everything was within Tang Feilin's plan.

Near the Pearl River estuary, the flood brought a large amount of sediment to the estuary, and even pushed the coastline southward by more than ten meters.

After the upper reaches of the Xiangjiang River are flushed, the river course is similar to that of the upper reaches of the Xijiang River.

Tang Feilin ordered the demolition of part of the south dam of the Lingqu Temporary Reservoir, and only the previous reinforced concrete dam was kept. The temporary dam on the river course must not be kept.

Of course, the project is not over yet, and the next step is to refine the Lingqu Canal and build several real reservoirs to regulate the water volume of the Lingqu Canal.

After finishing rushing the river, Tang Feilin left in a hurry.

Because the Pearl River (Beijiang)-Yangtze River (Ganjiang)-Zheshui canal has also entered the final stage.

In fact, this canal, such as Lingqu, was flushed early. During the coral typhoon at the end of last year, Tang Feilin took advantage of the huge typhoon precipitation to forcefully widen and deepen the canal.

As for the upper reaches of the Beijiang and Ganjiang rivers, preparations are made. As long as there is enough water in the temporary reservoir and there is a heavy rainstorm, the flushing can start.

Just recently, Jiangnan has entered the rainy season, and the precipitation in the upper reaches of the river is close to the critical point.

In fact, canals are still more cost-effective than railways in terms of cost performance, even in the 21st century, especially those bulk commodities that do not consider shelf life. If they can be transported by water, they will not choose to go by rail.

For example, in the Ruhr industrial area in Germany, the canal has not been eliminated, and it still serves as the main force for the transportation of iron ore and coal.

But Tang Feilin, Zheng Sen and others understood that the cost of building a railway was too high, and the maintenance cost was not low, especially in the ancient environment, the canal was the kingly way.

As for the railway, the North China Plain is the most suitable area for construction.

When Tang Feilin hurried to the upper reaches of the Beijiang River, the local water storage had reached the standard.

He quickly ordered the digging of the dam to flush the river.

The Ganjiang and Beijiang rivers were successfully flushed, and the river channel was expanded enough to pass ships of 200 to 500 tons.

...

Tang Feilin was busy wreaking havoc on the Yangtze and Pearl Rivers.

Zheng Sen has inspected Kunpeng 1 in Yangzhou City.

When the Kunpeng No. 1, which was like a mountain peak, slowly flew over the sky of Yangzhou City, it immediately caused a huge commotion.

Li Xiuning, Chai Shao, Shi Feixuan and others who were still in Yangzhou City stared at the behemoth in dumbfounded.

What exactly is this? Li Xiuning's mind went blank, even if she dared to go to the battlefield to fight the enemy, she felt terrified at this moment.

The representatives of various forces who were invited to observe the city wall, as well as the envoys of the small countries near East Asia, were all panicked at this time.

The Japanese envoys Fujiwara Dayi and Mo Lijing had panic and longing in their eyes, and they were thinking in their hearts how to get the Revolutionary Union to agree to their people to come and learn these technologies.

As for the Goguryeo envoys, when they thought of their bad relationship with the Central Plains Dynasty, they became even more frightened.

The envoys of other small countries also had mixed feelings.

Zheng Sen had a panoramic view of the expressions of these people, even when he looked at the envoys from Wa, Goguryeo, Silla, Baekje, Zhanluo, Funan and other small countries, there was a flash of sternness.

After a while, the airship made another move.

I saw a window open in the cabin at the bottom of the airship, and then a heavy bomb weighing more than 100 kilograms roared down from 500 meters in the air.

boom!

The makeshift bunker collapsed, sending bricks and debris flying in all directions.

As the envoys of the Zhuxia Alliance in the Human Revolutionary Alliance, Shen Luoyan and Xu Ziling's expressions were gloomy.

Xu Ziling even muttered to himself: How can our army resist such a killer weapon?

... Shen Luoyan couldn't even speak. At this moment, she understood what absolute power is. In front of such power, any city wall is no different from paper.

boom! Another heavy bomb hit the clearing.

A large crater with a radius of several meters exploded immediately, and the shock wave even made people on the city wall feel the smell of gunpowder in the air.

Several small tribal envoys from the Nanyang Islands were even scared to pee.

Zheng Sen said loudly: This is the power of Science and Dao. Any forces that try to prevent the RCRU from realizing the great harmony of the world will be wiped out.

Many people were already trembling with fear.

Even those who forcibly calm down are actually full of fear and anxiety in their hearts.

Zheng Sen ignored the panic of these people, because this was the effect he wanted, to defeat others without fighting.

The second half of this year is the deadline for the Human Revolutionary League to unify the Central Plains. The longer the war lasts, the greater the loss to the Central Plains. This is intolerable for Zheng Sen and others.

After this review is over.

The envoys from all parties had their own concerns, such as Li Xiuning, Xu Ziling and others, and they hurried back immediately.

Especially the Young Marshal Army and the Wagang Army, which are not in danger to defend, once the People's Revolutionary League attacks aggressively, the entire Huanghuai defense line will have no way to defend.

Especially on the side of the Wagang Army, Qin Shubao, Cheng Yaojin and others defected to Li Tang's side with a large group of subordinates, and many people defected to Kou Zhong.

Now the hearts of the Wagang Army are floating, and the sequelae of Li Mi's killing Zhai Rang have begun to erupt.

As for Li Tang, with the advantage of the bronze cannon, Li Shimin led the Tiance Army to completely defeat Liu Wuzhou at the beginning of February this year, and beat the intruders to the ground.

Then Li Shimin, who turned around, forced Liang Shidu to surrender again, completely wiped out the threat from Li Tang's north, and pushed the defense line to the Yinshan Mountains.

It's just that when Li Shimin's class teacher returned to the court, he found that the city of Chang'an was oppressed.

Inside Daxing Palace.

After reading the information Li Xiuning brought back, Li Shimin's face was extremely serious.

Even he, who is wise and powerful, feels helpless at this moment. After all, steam warships can still offset part of it by blocking the river and adding the dangers of Bashu.

And the airship flying in the air has no way to defend.

You can't shoot with a bow and arrow!

Erlang, do you think the artillery can hit the airship in the sky? Li Yuan asked unwillingly.

Li Shimin thought for a while: You can try it. If you can hit the airship in the sky, you won't be afraid of the airship of the thieves.

Li Xiuning gave another piece of good news: Father, the Fanzhai Master of Cihang Jingzhai intends to donate another 200,000 jin of copper materials to the imperial court.

Okay! I'm very happy with Samana's contribution to Datang. Li Yuan narrowed his eyes and smiled.

In fact, he didn't have a good impression of the Shamen headed by Cihang Jingzhai. In order to check and balance Cihang Jingzhai, the Taoist sect was made the state religion, and it was also inextricably linked with the demon sect.

This time, Cihang Jingzhai had to bleed a lot in order to protect himself, and asked the recluses in Guanzhong, Bashu, and Hanzhong to take out a batch of bronze elephants and bronze wares, which was enough to gather 200,000 catties of copper.

After all, the current copper not only represents money, but also force.

Li Tang, who has no blast furnace ironmaking technology, can only use bronze now, and bronze cannons consume too much copper.

Li Shimin, who returned to Tiance Mansion, quickly summoned his staff, including brother-in-law and eldest grandson Wuji, Fang Xuanling, Du Ruhui and others.

After everyone heard the news, there was a long silence.

Du Ruhui sighed: Oh! It's difficult! Your Highness, it's better to make plans early.

Is there really no chance of winning? Li Shimin walked up and down very unwillingly.

Du Ru shook his head helplessly:

Bashu, Guanzhong, Hanzhong, and Hetao, how to defend? Even if the artillery can hit the airship, the airship will not stay in one place, let the artillery attack, and there will be gaps everywhere on the border.

Changsun Wuji frowned: Then what should I do? The Kun bandits are killing us all, there is absolutely no possibility of surrender.

Fang Xuanling, who had been silent all this time, unfolded a map, pointed to a place and said:

For the current plan, there is only this way.

Li Shimin looked at that position with unbelievable astonishment in his eyes: Xuanling, how is this possible? Gaochang and other places can only support more than 200,000 people. I have so many people in Datang...

Suddenly he was stunned again, and then laughed bitterly at himself: Even if we really got to that step, how many people are willing to follow me and leave.

But Fang Xuanling continued to instruct: Your Highness, I am not only talking about the Western Regions, but also the west of the Western Regions. Therefore, Gan Ying of the Han Dynasty has been to the west. If his description is correct, Daqin should be there. Maybe we You can rest there.

This... Changsun Wuji hesitated to speak.

Fang Xuanling said murderously: Don't worry, Chang Shi. Since there are people in the old Han Dynasty who can go there, we still have artillery. At worst, we can destroy the Western Tutus and use their horses, cattle and sheep, and other countries in the Western Regions as transit.

Li Shimin walked up and down, and after a while he finally made up his mind:

This plan will not be made public for the time being. I am trying to manufacture artillery to attack airships, and at the same time send a large army to subdue the Western Regions and the Western Protrusions. After occupying the Western Regions, I will use the name of stationing troops to strengthen the frontier and move the population to the Western Regions.

Du Ruhui thought for a while and then added: Your Highness, if you want to subdue the Western Regions, I suggest a quick decision. If I'm not wrong, the Kun bandits will definitely attack Zhuxia in the Central Plains in the second half of this year.

Everyone was silent, and there was too little time left for them.

Changsun Wuji said viciously: Since we want a quick battle, we can't use the old method. We just don't do anything, kill all the nobles of the tribes along the way, and distribute their property to our soldiers. Part of it is given to the local people.”

Obviously, he is following the example of the Human Revolutionary League. If he uses this trick in the Central Plains, those tyrants will immediately rebel, but waiting for the aliens, they will not have such concerns.

If there is no revolutionary alliance, they may use a combination of hardness and softness, but now time is waiting for no one, and there is no way to quickly bring the Western Regions into rule without a quick knife.
