Reborn Before the Apocalypse: My Backing is the Nation

Chapter 113 Spear and Shield

It was a machine that resembled a minibus.

It is about ten meters long, and more than two meters wide and high. It is completely enclosed and covered with metal without any gaps.

It has four wheels at the bottom, and four poles extend to both sides from the upper part of the outer body, each with a wheel at the top, for a total of eight wheels.

In addition, it also has a "tail".

It is made of metal, connected to the vehicle body on one side and a cart-like object on the other. On the cart is a wing-shaped object made of pipes.

At this moment, it was placed in a downward-sloping passage made of transparent glass.

Not only the slope, but also the height and width of the passage are four meters, which matches the dimensions of the underground passage on the moon provided by Jiang Yang.

The wheels extending from the upper part of the vehicle to both sides rest directly against the glass.

After the restraints were released, under the influence of Earth's gravity, the "minibus," trailing its tail and wings, began to glide slowly forward. Wheels and poles extending from the sides of the vehicle restricted its direction of travel, forcing it to glide along the passageway and preventing it from veering off course and crashing into the wall.

Jiang Yang knew that electromagnetic communication was impossible in the lunar underground passage. In order to ensure complete protection, it was impossible to open windows on the vehicle. Therefore, the astronauts inside could not know the external situation, let alone actively control the direction of the vehicle.

Therefore, fixing its direction with these four rods and wheels became the only option.

Accompanied by Zhou Yu, Jiang Yang approached the glass passageway and immediately felt the chilling aura emanating from it.

To mimic the lunar environment, the temperature inside the glass tunnel is -30 degrees Celsius, and it is in a vacuum.

Stepping back slightly, Jiang Yang looked at the monitor next to him.

Numerous experts are closely monitoring the data changes. Furthermore, some internal monitors clearly display the situation inside the minibuses.

Jiang Yang saw two seats per row, and sixteen seats in eight rows.

Below the seat is something like bicycle pedals.

No one is pressing the pedal, yet it is rotating on its own. Clearly, people are using electricity to simulate the pedal being pressed.

As these pedals operated, Jiang Yang saw some transparent liquid slowly decreasing.

He knew that these transparent liquids were refrigerants.

The refrigerant in a typical household air conditioner is a hydrofluorocarbon, while the refrigerant in this case, which is a transparent liquid, is liquid nitrogen.

The operation of the pedal forcibly reduced the pressure in the space containing these transparent liquids, causing them to vaporize. Liquid vaporization absorbs heat.

Therefore, inside the minibus, heat is forcibly absorbed through pipes throughout the entire vehicle body, using liquid nitrogen as a carrier.

The steam then travels through the "tail" on the outside of the vehicle body and into the wing-shaped radiator.

Here, the steam, based on the energy from those pedals, is forcibly compressed into a liquid.

A large amount of heat is released and diffuses outward in the form of thermal radiation in the vacuum environment.

After the heat is dissipated, the liquid is returned to the pipes throughout the vehicle body by the manual compressor, and the heat is drawn out of the vehicle body again and sent outside. This cycle continues endlessly.

Under this device, Jiang Yang could clearly see that the temperature readings detected by the temperature detectors at dozens of points on the vehicle body were constantly decreasing, eventually dropping to -191 degrees Celsius.

This temperature is already below the critical temperature of a superconducting material called PYDD-6! Above -190 degrees Celsius, this material loses its superconducting properties, that is, it loses its superconductivity. Below this temperature, it enters the superconducting state.

Now, by simply attaching an ultra-thin metal sheet made of this material to the body of a minibus, its temperature can be reduced to below the critical temperature.

In the testing hall, a group of experts, their faces greasy as if they hadn't cleaned themselves in a long time and their eyes bloodshot, simultaneously let out a low cheer.

Jiang Yang breathed a sigh of relief.

Once the unmanned experiment was successful, the manned experiment began immediately.

The astronauts arrived in neat rows, wearing spacesuits that mimicked purely mechanical designs but with their weight deliberately reduced.

Jiang Yang saw one familiar face after another.

In his previous life, the scenes of those people willingly going to their deaths flashed before his eyes, giving him an urge to go forward and greet them.

Jiang Yang was overwhelmed with emotions, but the astronauts' gazes did not linger on him.

In this life, the astronauts do not yet know Jiang Yang.

A total of 16 astronauts entered the "minibus" and took their seats.

There are a total of 62 astronauts, but only 16 seats in the minibus.

People knew that the chances of these astronauts successfully reaching the moon were only about 20%, and even the 16 seats available at the moment were almost impossible to use.

Upon receiving the order, the 16 astronauts began pedaling vigorously in their seats, much like riding a stationary bike. Liquid nitrogen, acting as a coolant, began to flow, and the temperature started to drop.

The experiment was also successfully completed.

After completing these tests, the astronauts got to work. Under the guidance of relevant experts and in accordance with the design drawings, they quickly disassembled the "minibus" into its components and then reassembled it.

It was so big that it had to be disassembled before it could be loaded into the rocket. After arriving on the moon, the astronauts would have to manually reassemble it.

Repeat this process several times until everyone has fully mastered it.

Superconducting materials from all over the world have been gathered at the launch site, with a reserve of materials in case of rocket launch failure and the destruction of some materials.

All preparations are complete; it's time to launch.

Amidst the roar, rocket after rocket soared into the sky, some transforming into magnificent fireworks, others disappearing into the clouds.

Jiang Yang stood in front of the huge floor-to-ceiling windows in the observation hall, looking up at the sky.

"We are facing the most powerful enemy we have ever faced."

To fight against the enemy and against the apocalypse, we forged the hydrogen bomb, the sharpest spear, and with the combined strength of the world, we forged the PYDD-6, the strongest shield.

To our bravest and most resolute warriors, we now entrust this spear and shield to you. May you carry the hopes and blessings of all of us as you step onto the battlefield and face the enemy.

I wish you victory in this war, I wish you a safe return, and I wish our nation and our civilization can continue to thrive on this planet where we have lived and multiplied for hundreds of thousands of years…

The last rocket has been launched into the sky.
