Ship girls can breathe too, but this demand is different from humans and animals, and it is not a balanced breathing cycle.

They do not need to obtain oxygen in the air, do not need to directly use air to promote the redox reaction in their bodies, and then transport and use energy through body fluids.

The main function of the ship girls in daily breathing of air is actually to dissipate heat and discharge a small amount of waste gas.

If the ship girl only uses the ship girl's resources and does not eat human food, theoretically, it will not produce digested residues after food, which means there is no need to be dispersed.

There will only be a small amount of waste liquid and the waste gas needs to be released.

The function of inhaling and heat dissipating can be replaced by water or other methods.

But these are all on the ground and in the atmosphere. If you reach space, the situation will become more complicated.

When exposed to the sun, the temperature will rise rapidly, far exceeding the daily high temperatures that are endured on the ground.

When there is no sun, the temperature will drop rapidly, reaching more than one hundred degrees. If there is no sun exposure, it will even drop to a level close to absolute zero.

At this time, relying on breathing to assist in heat dissipation is useless...

In fact, this method is of no use and is far from truly controlling the body temperature of the ship girl.

Xu Xingchen and the ship girls both suspected that the ship girls' breathing activities themselves may have been deliberately added to imitate the characteristics of humans and animals.

After arriving in space, what ship girls need to consider is heat insulation and insulation.

After a simple test, Xu Xingchen and the ship girls discovered that the ship girls' skin was too powerful.

It looks crystal clear and soft and smooth to the touch, giving people a very delicate feeling, but in fact it is extremely tough and has the best thermal insulation ability.

With this powerful protective layer, the functions of the ship girl's body can achieve stable temperature control.

When Yuanwang No. 1 took off his helmet, he held his breath directly, and nothing abnormal happened after taking off his helmet.

Yuanwang 1 has been tested on the ground. If you keep your breathing in your hands, the ship girls can hold on for a few hours without any problem.

Even a few hours are not actually the limit, and there will be no problems with physical functions. It is just a mental discomfort that makes the ship girls unable to continue to persevere.

So now Yuanwang No. 1 is not ready to challenge the limit of holding his breath, but is ready to try to discharge the air in the body cavity to see what will happen.

So Yuanwang No. 1 carefully opened his mouth, ready to meet the feeling of complete suffocation.

When the air in the body cavity was rapidly leaking out and the environment in the body cavity gradually approached the vacuum, Yuanwang No. 1 felt a little stuffy, and at the same time, it was a little chill in the body cavity.

This feeling just now appeared, and a warm energy quickly spread from the corresponding position of the human chest cavity toward the surroundings.

The coldness inside the body quickly disappeared, and the warmth inside the body also returned to its heart.

And strangely, the feeling of stuffiness disappeared.

Yuanwang No. 1 tried to open his mouth and try to make his chest undulate. In an environment without air, this action should have no meaning.

However, as I simulated my breathing, the energy diffusion speed around the chest cavity began to accelerate, and the body's temperature also rose rapidly.

The temperature on the surface of the body quickly exceeded the body temperature of normal humans.

"This... this action is a functional module that can control and regulate body temperature..."

Yuanwang No. 1 muttered in his heart, and then tried to hold his breath again to prevent the chest cavity from undulating, and the energy diffusion speed would drop rapidly, and even the area would stop.

The body's temperature also slowly decreased, and eventually stabilized at a level similar to that of human body temperature.

"It is indeed used to adjust the temperature. It should be said that it is to actively control the temperature. Without control, the temperature will automatically stabilize..."

Yuanwang No. 1 nodded gently, and then tried to say his discovery, but found that he was completely speechless now.

After taking off the space suit, there was no air around my body, and the sound was completely impossible to spread directly.

Although the radio is still usable, it cannot make a sound by itself and can only transmit text and images. However, the barrier-free consciousness communication channel can be used.

Yuanwang No. 1 explained his discovery in the channel, allowing Black Fish and the sisters at the local base to record it.

Then Yuanwang 1 began to remove the spacesuit on his legs, and removed it until only the control pedal placed under his feet, holding the pedal directly in his hand.

Manually pull off the safety module under the pedal, completely disconnect it from the control line, and then throw it over.

The action of manually removing the control pedal is a sign that the first two stages of this experiment is over, and the door of the experiment cabin will not be automatically closed afterwards.

Far-watching No. 1 floated in the middle of the experiment cabin, curled up slightly, and looked at his limbs.

Leaving the thick space suit, he wore normal clothes directly, and moved flexibly and freely as if inside the Space Force Port.

An unprecedented sense of liberation spreads in consciousness.

By this time, the test has been basically completed and it can be basically confirmed that the ship girl can survive directly in the universe without relying on any external objects.

Of course, if you want to move in space, you still have to rely on other equipment, so the next stage of testing begins.

"The third phase of space exposure test is to unfold the ship-mounted propulsion equipment installed on the ship-mounted to move freely in space space."

Yuanwang explained the mission plan through the consciousness communication network, and then directly launched his own modified aircraft carrier.

In addition to the facilities of normal aircraft carriers, the ship is equipped with a large rocket engine and a small gas auxiliary thruster added by Xu Xingchen.

Yuanwang No. 1 tried to control the gas auxiliary thruster, and went straight, steering, retreat, rising, and rotating in the experimental compartment, confirming that there was no problem with all kinds of actions.

Then let the thruster push himself to the door of the hatch and manually press the button next to the narrow long door.

So, the outer walls of the entire experimental cabin slowly separated from the middle, revealing avenue leading to Tai Space.

Yuanwang 1 is preparing to test the rocket engine and test the rapid movement directly in space.

Before officially setting off, Yuanwang No. 1 subconsciously wanted to take a deep breath, which resulted in a slight increase in physical problems.

"I'm used to it..."

Yuanwang No. 1 shook his head helplessly and complained to himself in his heart.

Then he held his breath, hooked his feet to the telescopic guide rail buckle in the middle of the experimental cabin, and made a move to accelerate the start and accumulate force, and at the same time, he turned on the large rocket engine on the ship:

"Fuanwang 1, attack in space!"

A report was made in the consciousness communication channel, and his feet left the telescopic guide rail, and the whole person immediately flew out under the spurting flames.

After leaving the space channel, Yuanwang 1 controlled the steering of the rocket engine, quickly circled around the space military port, and tested various maneuvering actions.

Then he accelerated again, and the whole person flew into the distant space like a meteor.

Accelerate, accelerate, accelerate again...

Originally, it was just a simple straight-line flight, but the feeling of relief in Yuanwang No. 1's heart was upgraded again.

The boundless universe stretched around the body, looking at the vast starry sky in the distance, looking back at the blue planet underneath, looking at the heart of the No. 1 in the heart was extremely emotional:
Chapter completed!
