Chapter 329: Tunnel into the sea

In the rear of Datang Heavy Industry, a large factory building has been established where the relics of the prehistoric civilization of 10,000 years have been excavated, that is, where a dozen energy rifles have been excavated.
This plant is about two hundred meters long, one hundred meters wide, and twenty meters high. Among the large-scale plants of Datang Heavy Industry, it is still relatively small. However, there is Ye Fan’s underneath this plant. Shocking plan.
The so-called "Southern Sky Gate" plan is to build a large floating city pair channel, which is to directly open a channel connecting the South China Sea, and then from the bottom of the South China Sea all the way to the South Pacific.
"Crunch..." The painting of this large factory building is made of white. However, the ten-meter-high gate at the door adopts a black and white striped pattern, which looks a different kind of beauty.
This plant is still in a top-secret state among Datang Technology. Even the top level of Datang Technology cannot easily approach it. The vicinity is full of combat robots disguised as intelligent robots.
If someone is found trespassing here without authorization, these robots will expel them immediately and let the other party leave here, otherwise they will be knocked out and then forcibly taken away.
When Ye Fan walked into the factory building, the ten-meter-high gate was slowly closed. The moment the gate was closed tightly, the eight drones cancelled optical stealth.
At this time, Ye Fan's large steel armor had successfully emerged from the air.
In the interior of this plant, almost all are steel rolling machinery, as well as large and small molds and robotic arms, as well as hundreds of intelligent robots that are assembled with unknown materials.
In the center of the workshop, there is a big hole with a radius of fifty meters. It seems to be bottomless. I don’t know where it leads. The edge of this big hole is made of black steel. At the edge of the big hole, there is a light source. .
On the edge of the big hole, there is also a large elevator, all the way through the ground, it seems that this is to carry some large parts into the water to assemble.
Ye Fan jumped all his life and jumped directly into this big hole. At the same time, he started the ion engine and started to slow down his figure, and at the same time, he landed according to the altitude chart given by the origin.
This large hole is a thousand meters deep. It uses a large plasma cannon to evaporate the rock and soil into air and plasma to achieve such a scale.
Otherwise, just by collecting and digging, the excavated soil can be piled into a hill.
Of course, part of the rock was also excavated and sent to three heavy nuclear fusion reactors for fusion reaction power generation.
In this two-month period, in order to dig this tunnel, the origin can be said to be the construction of eight large plasma cannons, each can reach the speed of light, and can remove all soil with a radius of 40 meters and a depth of 3 meters. Evaporate.
However, in order to dig deep into this tunnel, both nuclear reactors are turned on at full power, just to charge a large number of super batteries.
And all the eight plasma cannons at the beginning of the game have reached the end of the life of the material. It took 13 plasma cannons to open the tunnel through the ground. You must know that this is only the first step.
The cost of each plasma gun is very high, reaching 300 million yuan. These 13 large plasma guns cost 3.9 billion yuan.
If these billions of funds are used fair and honest, and bidding for powerful construction companies, the cost even less than half of this point.
However, the concealment of the "Nan Tianmen" plan is destined to be a very money-burning project. If you want to save it, you can't save it. Otherwise, Ye Fan will not allocate 100 billion of Tamron Chip Group's funds to this plan.
"Papa." Relying on the reverse thrust of the ion engine, Ye Fan successfully landed on the ground. Looking up from the ground, he found that almost all of the sight was dark, even if the large searchlight provided the light source, it could not be changed. what.
This is because the large vertical tunnel that goes straight to the ground is made of liquid metal, and this metal has a very powerful ability to absorb light sources.
At the end of this vertical tunnel, there is an underground workshop made of white painted steel. Its length, width and height are more than double that of the large workshops on the ground, and several large boilers have been built here. , For metal smelting.
After all, if all the steel production of Datang Heavy Industry is used for the "South Tianmen" project, it would be impossible not to be discovered. Therefore, a batch of large-scale boiler equipment was built underground to carry out steel and iron work in the ground. Smelt.
In the ground, Origins invaded the data of several companies and obtained the construction drawings of a large shield machine. Then a large shield machine was built underground. After improvement and excluding energy loss, and excluding parts loss ~EbookFREE.me~ is advancing at a speed of 300 meters per day.
The underground space is a square, each side has a large semicircular tunnel with a radius of 30 meters, but three of them are built with reinforced concrete, and no rapid prototyping liquid metal is used.
Only one tunnel was constructed using liquid metal, because the large shield machine digs the road at a very fast speed. If the shield machine is unable to advance when encountering a solid rock, then the head of the shield machine is removed, and then Use plasma bombardment, and then assemble the shield machine for propulsion.
This tunnel leads directly to the seaport, while the other three tunnels are all digging towards some local veins. After all, to smelt liquid metal, a large amount of ore is needed for support.
Therefore, under the support of three underground iron ore veins, the ore demand that supports the "South Tianmen" project can barely account for more than 40, and there are still 60 ore needs to be imported from the outside.
There is also a large amount of excavated soil, which is thrown into the sea directly through the tunnel into the sea, avoiding exposure to the greatest extent.
Because this tunnel made of liquid metal leads directly to the bottom of the sea, it is inclined at a 20-degree angle. After two-thirds of the distance, seawater has already poured in.
"Wow!" Ye Fan started the ion engine, and the two-thirds of the journey was a direct leap, and finally came to the end of the tunnel, which was the section of road full of sea water.
Ye Fan began to walk towards the end of the tunnel step by step. The size of the steel armor is actually a "sandwich" mode. Every time the water level dives, seawater is injected into the steel armor. , And then go through the stabilizing device exchanged from the system to seek the absolute balance of internal and external water pressure.
