The rise of nanometers

January 28th.

After more than a week of refinement, Chu Xuan formulated a very complete plan.

The Sierra Madre Occidental Mountains in northwestern Mexico connects the southern Rocky Mountains. Deep underground in the mountains, at a depth of approximately 1,375 to 1,582 meters, there is an unknown natural underground passage.

Of course, this kind of underground passage is not always connected. The Intelligence Department and the Institute of Geology have collected a wealth of North American underground rock formation data through several years of research.

These underground caves, underground interlayers, etc. are more or less distributed deep underground in many mountains.

They may come from erosion by flowing water, formed by stratigraphic fractures, or formed by the decomposition of minerals.

This underground passage is located very deep underground, and there are many underground caves and cavities that are not connected to each other. There are also severe conditions such as collapses, poisonous gas, and water areas.

Under normal circumstances, it is difficult to develop.

But the number of underground caves in North America, or the American Rockies, Andes, and Central American mountains, all have dense and coherent underground caves.

In order to improve this plan, the Intelligence Department also commissioned the Suiren Department to open a vest company and purchase several mountainous areas in the Sierra Madre Occidental, nominally to develop local coal mines and copper mines.

In fact, the mine was used as a cover to build an underground secret passage.

In order to ensure the confidentiality of the project, the construction principle of the secret tunnel is to use underground caves and underground rivers as much as possible, and then use chemical agents to corrode the excavation.

After more than a year of improvement, this secret trail can reach from the northern part of the Sierra Madre Occidental Mountains to the vicinity of the Grand Canyon Park in Arizona.

If it weren't for the use of natural caves and underground rivers, this 1,274-kilometer secret tunnel would be a fantasy. No one would believe it even if it were told.

In fact, the length of this secret tunnel that really needs to be excavated is only about 281 kilometers, the natural caves are a full 624 kilometers, and the rest are underground rivers.

Even in areas that need to be excavated, the Intelligence Division has adopted the latest tunnel excavation technology, namely chemical corrosion + water erosion, to reduce vibration and sound wave transmission.

Using the cover of the water flow of the underground river and the tunnel they dug, the radius is only about 1.2 meters, which only needs to accommodate one person to pass through.

The new chemical corrosion agent corrodes the rock formation very quickly. Under the maximum tolerance of sound waves, it can dig 500 to 900 meters per day. This is a very amazing technology.

This is also the reason why this secret passage can be completed quickly.

In order to cooperate with this operation, Chu Xuan also spent a lot of money.

James, who was transferred from Australia, had a serious face at this time. He wore a diving suit and entered the underground river with three other colleagues.

James had no choice. After being captured by Chu Xuan, he was forced to become a double agent and sent a lot of half-true and half-false information to his old master Britain. Now he could no longer get off the ship.

Moreover, Chu Xuan is not a pedantic person. If he dares to use James, it means that he has made all preparations, such as the bionic nanochip implanted in the brain, and James' family.

If James dares to make a small move, his life will be at risk in a minute, and he may not even be able to leak a word.

There is no other way to use James. The main reason is that North America has been very wary of Asians and Chinese in recent years.

The skin color is too obvious, making it difficult to get close to the target. Even if the mission is successfully performed, it is difficult to escape safely.

Moreover, Chu Xuan is very afraid of Naoting's brain-reading equipment. Once the personnel are caught by the opponent, it may lead to the exposure of secret underground passages in North America.

This secret passage was built to play an important role in the future. It cannot be scrapped just because of a single mission. Such a loss would be too heavy.

Equipped with a submersible exoskeleton and a jet thruster, the four swam through the last 8.7 kilometers of underground river area and came to an underground cave.

This place has been transformed, and three agents are stationed there. After preparing a series of equipment for the four of them, they began to take action.

In addition to James, there is another white man on the special team, but he is from the region.

After leaving the cave and walking down a long and narrow rock path for more than fifty meters, we entered an abandoned gold mine cave. The mines here extend in all directions. If there are no professionals to guide the way, it is easy to get lost in it.

Moreover, the most dangerous aspects of abandoned mines are the risk of collapse and excessive concentrations of gas and carbon dioxide.

The carbon dioxide concentration in this abandoned mine is about 4 to 5 times higher than normal.

Wearing special gas helmets, they quickly arrived outside the mine following the obscure warning signs on the rock wall of the mine.

Team leader Wu Di made a few gestures, and everyone quickly took off the gas helmets, hid them in the prepared boxes, and then placed them in the small mezzanine above the mine, and covered them with wooden boards.

They felt a chill. Although the latitude of the Grand Canyon is not high, its altitude is about 1,000 to 3,000 meters. It is winter in the northern hemisphere, so the temperature is naturally not much higher.

Fortunately, the Intelligence Department had made a rigorous plan and had already taken the weather into account. They had special warm clothes on them, plus the clothes and backpacks provided by the cave base, which was enough for them to live in the wild for a week.

Taking out his telescope, Wu Di stood on a high slope and looked at the small city in the distance - Tiba City.

This small city is not far from Grand Canyon City, but it is very far away from their mission location.

This time their mission was to Salt Lake City, 660 kilometers away, a large city near the Salt Sand Base.

While it's still dark.

Wu Di took James and others to Tiba City not far away. The Intelligence Department had prepared ID documents and a small amount of change for the four of them.

An hour later, one of the team members left the team and lurked near the small town. There was a small farm here, which was purchased by a wealthy Panamanian man who "happened" to return to Panama for the winter.

The team member entered the farm house without anyone noticing.

Only he and captain Wu Di knew about this hidden stronghold, and neither James nor the two knew about this place.

As for Wu Di and the others, they checked into a motel as tourists in California, and then prepared to rent a car and head to Salt Lake City tomorrow.

Since it was in the hinterland, the motel owner didn't have much suspicion about the three people. Although one of them was Asian, there were two white people together.

In addition, James is eloquent and has a familiar skill, and he quickly struck up a conversation with the boss.

After eating hot dog buns and fried chicken, Wu Di and others went to rest.

In the dead of night, James glanced at the dark tree shadows outside the window and sighed softly. Thinking back to his life, he couldn't help but smile bitterly.

Born and raised in Scotland, he married a wife and had children in Australia, and then inexplicably became a member of Greater China. Now he wants to become 007 and destroy evil organizations.

This fucking life.

Maybe after he retires, he can consider writing an autobiography, which will definitely sell well.

Pushing the random thoughts out of his mind, James closed the curtains and lay down on the bed to sleep.

at the same time.

In the Yansha base, after the three Valentines completed the loyalty test, they finally began to conduct batch tests on the internal personnel of Brain Court. The first batch included 10 people.

The reason why there are so few is not because there is not enough equipment, but because there are not enough operators and medical staff. They need people they can trust before they can gradually expand the scale of testing.
