Homo sapiens

After arriving at your destination.

It was already three o'clock in the afternoon.

That section of low mountains cannot be seen from the main river, and you still need to pass through a valley.

However, everyone has already disembarked in the main river, because technical testing can be carried out in this valley, and the project itself also needs to start excavation from this valley.

Judging from the drone's terrain scan, the valley presents a V-shaped outline, with a small river flowing down from the mountains in the middle.

The engineering team set up camp next to the relatively open and flat valley mouth.

Then start working on the forest on both sides.

I saw dozens of construction workers wearing work-type exoskeletons. They were all new human employees and there was no problem of leaking secrets.

The iron bamboo pipes unloaded from the transport ship were pulled into the forest and then assembled. The pipes were laid on the ground, similar to scaffolding in construction.

The racks are then connected together, and then the pipe is driven deep into the ground through a small drilling machine.

A total of 100 underground pillars were built in this area of ​​nearly 10,000 square meters.

After finishing these tasks, it was already the afternoon of the third day.

At this time, on top of each underground pillar, a ground pillar was installed just beyond the crown of the tree. On the top of the ground pillar, there was a green sphere larger than the washbasin.

Mangshan, the captain of the engineering team, carefully checked the lines of the 100 ground pillars. After finding that there were no problems, he ordered the technicians:

"It's ready to unfold."

"clear."

As the switch was pressed, the top sphere of the ground pillar quickly unfolded, and the green organic matter skeleton controlled in all directions, turning into hemispherical skeletons.

Due to some differences in the height and position of the pillars, these green skeletons look like trees without leaves.

Lines connected to nutrient storage containers deliver nutrient solution to these skeletons.

The special genetically modified plant implanted in the green skeleton began to grow and develop.

In less than three days, the skeleton has been covered with green leaves, looking like towering trees, and just covering the natural trees below.

This is a vine-type genetically modified plant that uses pineapple and ivy as the mother base. It does not require soil. It only needs sunlight and water, plus a certain amount of nutrient solution, to maintain its vitality for a long time.

Homo sapiens calls this genetically modified plant and artificial skeleton the "Green Umbrella System."

This thing is much cheaper than steel structures and has very low maintenance costs. It is used in tropical rainforests to disguise itself as a natural forest and is definitely more concealed than steel structures.

Even geological remote sensing satellites have no way of detecting anomalies.

Unless someone can enter the scene to conduct reconnaissance, it is basically impossible to find the problem simply by relying on long-distance radar and photography.

In order to avoid being discovered here, Siam will establish this area as a nature reserve in the near future, move all surrounding villages out, and set up a reserve patrol team.

After the green umbrella system is deployed.

The engineering team begins to cut down trees. The huge logs will be transported downstream along the waterway, while weeds, branches and leaves will be thrown into the fermentation tank of the fermentation ship to produce methane.

This methane can be supplied to the engineering team for their own use, reducing external fuel input.

After clearing away the trees and weeds, the ground revealed dirt and gravel.

This is where the second new technology comes into play.

In the area that needs to be excavated, drill down to the specified depth with the drilling machine.

For example, here, the drilling depth is 20 meters, and then special genetically modified bacteria are injected into the well. These bacteria will parasitize on the rock formations under the action of hormones and nutrient solutions, destroy the structure of the rock formations, and turn the rock formations into fine gravel. .

The specific type of bacteria used can be determined based on the composition of the underground rock formation.

This kind of bioerosion takes about a week to destroy the rock layer within 25 to 30 meters underground.

Similarly, the remaining tree roots can also be decomposed using specific genetically modified fungi. It takes about a week to turn these tree roots into a rotten state.

After destroying the rock formations and tree roots, only small particles of sand and humus are left in the stratum, and you can proceed to the next step.

Water and air are injected into the well to cause fluids to boil in the surrounding formation, similar to an ebullating bed.

Due to the terrain height difference and being next to the river, the sediment will pour towards the river under the influence of the terrain and the earth's gravity, as if a debris flow erupted.

After the sediment enters the river, the air nozzle installed at the bottom of the river will continuously spray air, making it difficult for the sediment to settle and has to flow downstream.

Near the construction site of the Dangweng River Dam downstream, the engineering team deployed a large number of sand pumping boats to continuously pump sand from the bottom of the river to artificially increase the depth of the river.

As the downstream river channel becomes deeper, it can accommodate more sediment accumulation.

These river sands can be used as raw materials for building dams and cities.

Kill two birds with one stone.

The sediment content of the river water will surge significantly in a short period of time, which will accelerate the speed of land reclamation in the Salween River's estuary delta.

Especially during the rainy season every year when the river water surges.

The transportation effect of formation fluid boiling technology will be better.

On the other hand, considering that after the dam is built in the future, the entire valley will be submerged in low-lying areas, Homo sapiens will also start another job, which is to pump sand to fill the valley.

The low-lying areas along the river will be artificially raised using sediment from the river.

The current project at this location is just an initial test. Once it is launched on a large scale, it will not be tens of thousands of square meters, but several square kilometers.

Even if the mountains are relatively high, they can be peeled off layer by layer, and finally the mountains can be turned into flat valleys, so that the river water can flow directly from both sides to join together.

According to the project plan, the central canal hub project in the Thanianthavang Mountains is 21 kilometers in length, 500 meters in width, and 30 meters in depth.

In order to ensure that the water level can be stable, several large reservoirs will be built in the surrounding area.

But when Wu Nan and Liu Zhifan came here to inspect, the engineering team had expanded from the previous 150 people to 632 people.

The green umbrella system covers an area of ​​1.3 square kilometers.

Wu Nan and Liu Zhifan took a boat and entered the green umbrella that obscured the sky and the sun. They saw the area where the sediment layer had been washed away, almost forming a small lake.

"I almost didn't notice this green dome from the outside. I didn't expect that the inside had been hollowed out."

Liu Zhifan said with a smile: "The leaves above are real, and satellites cannot detect the construction inside."

"It seems that it is necessary to strengthen the management of the surrounding areas. How about deploying a division to station nearby?" Wu Nan suggested.

But Liu Zhifan shook his head: "It's not enough to go too far. Just use a patrol team composed of new human employees. The army is too conspicuous."

Wu Nan immediately reacted: "That's true."

After listening carefully to the technical staff's introduction, Wu Nan initially understood the role of these new technologies. He said with emotion: "At this rate, it will probably be completed here in less than a few years."

"If everything goes well, it will be completed in about 15 months, which is faster than the Dam Weng River Dam."

When Wu Nan heard this time, his expression was a little helpless: "It seems that after I go back, I will supervise the progress of the Chao Phraya River's transformation to avoid being delayed."

"Although the progress has to be rushed, confidentiality work should still be done well." Liu Zhifan reminded.

Wu Nan also knew the seriousness of the matter and nodded seriously: "I will pay attention."

Thank you for your support (ω｀), and thank you to book friends "Kun Lin Yuan Shan" and "Sunny Day One" for their rewards.
