Upon arrival at your destination.

It was already three o'clock in the afternoon.

That section of the low mountain range, which cannot be seen from the main river, has to pass through a valley.

However, the people have already disembarked from the main river, because the technical tests can be carried out in this valley, and the work itself will have to start digging from this valley.

From the drone's topographic scans, the valley has a V-shaped silhouette, with a small river flowing down from the mountain in the middle.

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

Then the treatment of the forests on both sides began.

I saw dozens of construction workers wearing work-type exoskeletons, they are all new humans, and there is no leakage problem.

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

The shelves are then connected together, and then the pipes are driven deep into the ground by a small drilling rig.

In this area of nearly 10,000 square meters, a total of 100 underground pillars have been built.

After doing all this work, it was already the afternoon of the third day.

At this time, on top of each underground pillar, a ground pillar is installed just beyond the canopy of the tree, and at the top of the ground pillar, there is a green sphere larger than the basin.

The leader of the engineering team, Python Mountain, carefully inspected the lines of the 100 ground pillars, and after finding that there was no problem, he instructed the technician:

"It's ready to be expanded."

"Understood."

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

There are some differences in the height and position of the pillars, making these green skeletons look like trees without leaves.

Lines that connect nutrient storage containers deliver nutrient solutions to these skeletons.

A special transgenic plant implanted in a green skeleton begins to grow and develop.

In less than three days, the skeleton was already covered with green leaves, which looked like towering trees, and just shrouded the natural trees underneath.

This is a vine-type transgenic plant that uses air pineapple and creeper as the mother base, which does not need soil, only sunlight and water, plus a certain nutrient solution, can maintain life for a long time.

Homo sapiens has turned this genetically modified plant and artificial skeleton into a "green umbrella system".

This thing is much cheaper than the steel structure, and the maintenance cost is also very low, and it is used in the tropical rainforest, camouflaged as a natural forest, and it is definitely more hidden than the steel structure.

Even geological remote sensing satellites have no way to detect the anomaly.

Unless someone can enter the scene to reconnoitre, it is basically impossible to find the problem by relying on long-range radar and photography alone.

In order to avoid being discovered here, Siam will recently set up the area as a nature reserve, move all the surrounding villages out, and set up a patrol team for the reserve.

When the Green Umbrella system is deployed.

The engineering team began to cut down trees, huge logs were transported downstream by water, and weeds and twigs and leaves were thrown into fermenters on fermenters to produce methane.

This methane can be supplied to the engineering team for their own use, reducing the amount of fuel input from the outside world.

After the trees and weeds were removed, the ground was exposed with dirt and sand.

This is where the second new technology comes in.

In the area where excavation is required, drill down to a specified depth by a drilling rig.

Here, for example, the depth of drilling is 20 meters, and then several special genetically modified bacteria are injected into the downhole, which will parasitize the rock layer under the action of hormones and nutrient solutions, destroy the structure of the rock layer, and turn the rock layer into fine gravel.

The specific type of bacteria to use can be determined according to the composition of the underground rock formations.

This kind of bioerosion can destroy the rock layer within a range of 25~30 meters underground in about a week.

Similarly, residual tree roots, which can also be broken down using specific genetically modified fungi, can also be turned into a rotten state in about a week.

After destroying the rock layers and tree roots, the formation is now left with only small particles of sediment and humus, and the next step can be moved.

Water and air are injected into the well to allow the surrounding formations to form a fluid boiling state similar to an ebullation bed.

Due to the difference in elevation and the fact that it is located next to the river, the sediment will be poured into the river under the action of the terrain and the earth's gravity, as if a mudslide is erupting.

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

In the vicinity of the construction site of the Dangweng River dam downstream, the engineering team arranged a large number of sand pumping boats, constantly pumping sand from the bottom of the river, artificially increasing the depth of the river.

The deeper the downstream channel allows it to accommodate more sediment accumulations.

This river sand can be used as raw material for the construction of dams and cities.

Kill two birds with one stone.

The sediment content of the river will surge in a short period of time, which will accelerate the rate of land reclamation in the estuary delta of the Salween River.

Especially during the rainy season every year, when the river is swollen.

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

On the other hand, considering that after the dam is completed in the future, the entire valley will be submerged in low-lying areas, and Homo sapiens will carry out another work, that is, sand pumping and filling the valley.

The low-lying areas along the river are artificially raised by using sediment from the river.

The current project at this location is only a preliminary test, and once it is carried out on a large scale, it will not be tens of thousands of square meters, but several square kilometers together.

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 can directly flow from both sides to converge.

According to the planning of the project, the central canal hub project in the Ta Nin Thanon Mountains has a length of 21 kilometers, a river width of 500 meters, and a river depth of 30 meters.

In order to ensure that the water level can be stabilized, several large reservoirs will be built in the vicinity.

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

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

Wu Nan and Liu Zhifan took a small boat and entered the green umbrella that was hidden in the sky, and saw that the area that had been washed away from the sediment layer almost formed a small lake.

"I barely found this green dome on the outside, and I didn't expect it to have been hollowed out inside."

Liu Zhifan said with a smile: "The leaves on it are real, and the satellites can't find the project here." ”

"It seems that it is necessary to strengthen the management of the perimeter, or should a division be stationed nearby?" Unan proposed.

But Liu Zhifan shook his head: "It's too much, it's enough to use a patrol team composed of new humans, the army is too conspicuous." ”

Unan immediately reacted: "That's the same." ”

After listening carefully to the introduction of the technicians, Unan initially figured out the role of these new technologies, and he said with emotion: "At this rate, it is estimated that it will not take a few years to complete here." ”

"If everything goes well, it can be done in about 15 months, which is a little faster than the dam on the Donong River."

When Unan heard this time, his expression was a little helpless: "It seems that after I go back, I will supervise the progress of the transformation of the Chao Phraya River, so as not to delay when I get there." ”

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

Unan also knew the seriousness of the matter, and nodded solemnly: "I'll pay attention." ”

Thank you for your support (ω'), and thank you for the rewards of "Kunlin Yuanshan" and "Sunny Day".
