Now the Republic of Dawn is becoming more and more mech manufacturers are becoming more and more flexible with the development of the chip industry, and the mech operating system is becoming more and more flexible, and there are signs of competition among companies specializing in the production of civilian models of mechs. The construction of the Republic of Dawn has not stopped, so the demand for engineering mechs is very strong, which has driven the development of the mech industry to adapt to market demand.

Some good engineering mechas are sometimes comparable to military combat mechas. These engineering mechas are manufactured and are selectively purchased by the government of the Republic of Dawn. Therefore, these high-end mechas are still artificially made.

What is the Dawn Republic for purchasing these engineering mechas? The answer can be found in Watchtower City in the western Dawn Republic.

Watch City has been built for 12,000 years. Since the record of the Yuanmiao Continent, the entire city has always appeared periodically in the history of mainland warfare. Watch City is a highland on the alluvial plain in the west. Whenever the magic tide period is during the period, the south of the west and south of the Yuanmiao Continent will always be cleaned by astronomical tides. The annual tide washing can make the entire continental plain in swamp for many years. A large amount of sea water remains in the soil, filling all low-lying areas to form a large lake, which cannot be subsided in one or two years. However, this astronomical tide is once a year. This stage is the time when the sea tribes and the mainland races fight each other. Watch City is a place that must be fought for by the corps of both sides.

The magic tide is just beginning now, and the annual tide line has been advancing towards the mainland year by year. Signs of the astronomical tide soaking the entire Western continent have appeared. It is expected that twenty years later, this historical scene may really appear.

However, today, industrialization has begun, and a large amount of bauxite mines near Watch City have become the core of Watch City's manufacturing. In the past twenty years, this city of 120,000 people has attracted a large number of farmers from the plains to enter the city, learn technology, and become industrial workers. With sufficient energy in the city, the city has achieved a terrifying output of 900,000 tons of electrolytic aluminum per year. The scale of this smelting aluminum is comparable to the scale of steelmaking using coal mines on the earth. The reality is that there is no fossil fuel in the area, and steelmaking is really not as convenient as aluminum.

So now the Republic of Dawn uses a large amount of lightweight aluminum materials. The entire Watch City, except for the lack of particularly high skyscrapers, is actually very modern. The wide roads and various vehicles. The 50-meter-high stopping platform stands in various areas of the city. A four-axis #aircraft with a rotating propeller with a length of 15 meters is busy flying over the city with a load of several tons of heavy objects, shuttled through the sky and formed a logistics network corresponding to the shuttle of ground vehicles.

However, from the surroundings of the developing city of Skybird Olive, you can see that a huge dam structure with dozens of kilometers long to the west of the city is being built. A large number of red-coated engineering mechas shuttled through this large construction site. After the foundation was laid, huge aluminum pipes were inserted. The five-meter-high mecha engineer held the metal pipe with his hands and connected the metal pipes below, just like building a building block. The huge aluminum metal pipes were inlaid with circles of grid iron sheets.

When the two metal tubes were connected, more than ten palm-sized robots crawled out of the cool box behind a engineering mecha. These palm-sized robots climbed onto huge aluminum tubes and climbed on the official road like beetles. These machine beetles had powerful magnets on their feet, which is why the aluminum tubes were covered with iron grid layers. These machine beetles were distributed on both sides of the docking of huge steel tubes, corresponding to alternately emitting the red laser, so whether there were aluminum tubes or not? These machine beetles were neatly matched.

The insect observed very carefully. The engineers who controlled the engineering mecha, according to the information sent by these robots at any time, carefully spliced ​​the aluminum tubes to a satisfactory level. Then a special crawling robot crawled out of the box behind the engineering mecha. The robot came to the splicing gap and followed the straight line marked by the engineering mecha with lasers and used an arc to create high-temperature ion states. The dark blue ion arc was thinner than the pencil core, and it hit the gaps extremely accurately. The gaps were melted and seamless welding was completed.

After completing this docking, a thinner robot arm popped up on the huge arm of the engineering mecha. The high-definition camera on the robot flexibly investigated the degree of welding. After the engineer sitting in the mecha compartment determined the degree of welding of the robot, he let all the robots crawl back to the toolbox behind him and continue to do other work.

In the past series, the engineers of the driver mecha not only carried the physical work of carrying a huge ten-meter-long aluminum tube, but also completed the medium-level technical work of alignment, and finally supervised the robot to complete the precise welding work. The entire dam, a spectacular building that could only be seen in the era of the Magic Empire, is being built in an orderly manner.

The Republic of Dawn is preparing to protect eastern cities with this super defense system. At the same time, in order to ensure the safety of the freshwater source of Blue River, the entire Republic of Dawn has dug a large number of artificial canals to target Blue River to make full use of the water of Blue River.

This is why the Empire's engineering mechas are in high demand now. The tsunami-proof dam system in big cities is actually not a big project. It only takes two thousand high and low engineering mechas to cooperate with each other and can be easily completed within one year. The 50-kilometer tsunami-proof dam system. These tsunamis will only be built to a height of 35 meters at most. Because a 35-meter tsunami will only break out on the sea after falling from meteorites on the ocean or a major earthquake under the sea. As for the tsunami sweeping onto the land, it will be a few meters high. You only need to maintain this aluminum-tube structure mixed territory dam on the front facing the western waves. As for other parts, you can directly dig a map and pile up seven or eight meters of earth dams to block the turbulent storm during the days of the year.

For their own safety, cities in the western plains allocated a financial amount to support the construction of the dam, which brought good news to the cement industry in the Dawn Republic. Of course, this is just a city-level defense plan. As for the national defense plan, the scale is even larger.

Compared with the plan to defend against sea tides, the Republic of Dawn was determined to completely eliminate the tide and invisible. In the winter of the five years, the Republic of Dawn conducted 372 underground nuclear explosions underground in the western part of the country, with each nuclear explosion equivalent to 1,000 tons. The seismic waves caused by such explosions appeared one after another on the western continent. Through seismic wave research, the locations of several underground spaces in the western continent of Dawn. These underground spaces are derived upward like caves with a diameter of capillaries of hundreds of meters, and are mostly only five or six kilometers away from the surface.

There is a saying, how come a city’s conscience lies in the sewer. A city is soaked in rainwater because the city’s drainage system is not good. The west coast of Yuanmiao continent was ravaged by astronomical tides a year during the elemental tide period, and then the water cannot recede, and the entire western continent is flooded all year round. If the tide comes once a year, then after a month, all the water on the continent retreats into the river channel, all the water on the continent disappears, leaving dry land, then as long as all the humans on the land hide in the city that month, there will be no impact at all.

That's right, the senior management of the Republic of Dawn prepared this way, preparing to dig an epic-level pit for the landed sea tribes. A pit that caused the flood caused by the astronomical tide will be completely eliminated within one month.

Ren Di originally planned to name this huge project with a "sewer", but the gang of school officials in the Republic of Dawn could not stand Ren Di's name this time.

Looking at this huge plan, Wang Long said in a somewhat undeniable tone: "Dayu controlled the flood and stood in China, so it was called the 'Xia' plan. What do you think?" Wang Long looked at the people around him, and then his eyes fell on Ren Di. Although he was asking, the meaning was very obvious. If there was a relatively low-level naming plan, don't mention it.

Finally, the summer plan was implemented by the state. The plan implemented drilling holes above twenty detected underground spaces in the western territory, and then excavated in various parts of the western land. The canals with higher riverbeds will not enter water. Usually, these artificial riverbeds that are slightly lower than the ground will not enter water. When the astronomical tide arrives, the water level in the natural river channels in the western continent soars, when these river channels are filled with water, these river channels will then send water into the patio with a diameter of 50 meters and pour into the underground space.

In this way, every time the sea water soaks the continent, after the tide is gone, the water first enters the waterway, then enters the large number of artificial waterways excavated, and finally seeps into the underground. As for what impact so much seawater has on the possible ecosystems in the underground world, this dead fellow is not dead. Ren Di Zhuo Water harms the neighbors. If the seawater fills the underground, it will be beneficial to the stability of the underground.

The huge drilling rig drilled underground under the surging nuclear power. A large amount of soil was excavated and sent to the surface at any time. Although the plan was to dig out a channel with a diameter of 50 meters to reach the underground, in fact, a loophole of about 300 meters was formed on the surface. In this loophole, various working platforms serve large machines for underground drilling.

On the western surface, a large number of artificial rivers are being excavated. Now the tides that are soaked in the continent are less than one-tenth of the land that is soaked in the astronomical tide at its peak. As long as the underground infiltration channels are dug through, these rivers are assembled to this one-tenth of the area. This one-tenth of the area can be restored to dryness.

The feat of human beings to challenge nature has begun to form as rivers on the surface are being excavated in a network shape, and artificial veins of the earth are being formed.
