The place where Shen Yun came said to be a hut, but in fact, the real name is "Preparatory Room", and AI Intelligence also calls it "Transition Zone".

On the door of the preparatory room, a line of red light is clearly marked: C Training Ground of the First Regiment of the Space Force.

On each side of the wall is a sign with a slogan, and on the left is "Defend the country and fight for the civilization of the earth". On the right is "work hard and stand hard work, don't disgrace your hometown fathers".

The "hometown" in the latter sentence must refer to the motherland of a group of soldiers - China, seeing such a slogan, Shen Yun felt that the blood in his veins was boiling, and a sense of pride rose from the bottom of his heart. She thought to herself, her father, who was a member of the Communist Party, should have felt the same way when he stood here, right?

However, Field C, which encompasses the panoramic view of the universe, must be extremely spectacular, and since it can be combined with the global Field C to form an open exercise environment, the estimated capacity is also extraordinary, why is the transition area so narrow?

This is a new question, and the explanation that Shen Yun can find is similar to the principle of optical flow shuttles and capsule trams - maybe the hut also belongs to that kind of miracle, which seems to be not big, but can actually accommodate thousands of troops and horses?

Cao Fang and Yao Zheng aimed at the identification system on the door, pressed the national flag on the left chest, and immediately the voice of AI appeared, this time it was from a deep man, and said in a majestic voice: Welcome to the third level of the Light Continent, starting from 700 kilometers underground to enter the state of weightlessness, please prepare the step balancer equipment, and pay attention to safety. ”

Cao Fang turned around and said to Shen Yun with concern: "The third level of the Light Continent is the deepest underground we can reach at the moment, and it is not suitable for humans to go further down. However, the in-depth study of the Earth's core has never stopped, so in fact, the real depth of the C field is not only 700 kilometers, and the natural temperature outside the absolute zero environment is not low, which leads to excessive gravity, and it is necessary to set up a super reaction force to simulate the weightless environment of the universe. Compared with real weightlessness, this kind of environment tests the endurance of soldiers, and although it can provide unique conditions for military training, it also increases the danger of entrants. That's why Field C is the toughest of all the training grounds.

Shen Yun understood the implication of Cao Fang's explanation, and said firmly: "Commander Cao, please rest assured, if all the soldiers of the first regiment can enter Field C, I will not have any problems." What to do next, please indicate. After speaking, he lowered his head and habitually tidied up the solid-state light military uniform on his body, although this uniform would not wrinkle.

Cao Fang nodded in satisfaction, gave Yao Zheng a thumbs up, and signaled everything to "OK", and the latter pressed his right index finger on the fingerprint module displayed by the identification system. Just listen to the sound of "boom", like a light streamer, the door of the preparatory room slides open to both sides, and the AI invites you to enter the transition area of Field C.

The C-field transition zone is the middle ground between the earth world with normal gravity and the simulated weightless universe. The room is equipped with a gravity adjustment system, once activated, all doors and windows will be sealed by pneumatic adhesive strips, and the air will be gradually pumped away, simulating a weightless environment. This simulation system has a progression from low to high, which the entrant can adjust as needed to avoid the discomfort of suddenly "floating".

In one corner of the room, there was a three-story black equipment rack, and several pairs of military boots that looked like roller skates were scattered at the bottom of the rack, and it seemed that no one had touched them for a long time. Next to the shelf is a large rectangular table with dozens of pairs of AR glasses that can cover half of your face.

Yao Zheng visually inspected Shen Yun's feet and quickly found a pair of military boots for her.

Shen Yun took off his shoes and carefully put his feet on his boots, but found that he couldn't stand up at all. Because she couldn't roller skate, the soles of her roller skates couldn't keep her balance, so she had to sit honestly on a bench for changing shoes.

After the three of them had changed their boots, Yao Zhengcai clicked on the words "Level 1 Start" on the electronic screen on one of the walls.

It was as if there was a turbid wind, blowing from nowhere, holding up Shen Yun's body. She felt like she was losing weight, and she was sitting, but her feet were slowly off the ground.

As an ordinary person who has never had experience in space travel, her nervousness can be imagined.

However, to her surprise, as soon as her body became a feather, there was a force under her feet, which pressed her down to stabilize, and only her upper body was still shaking, as if she was drunk.

Cao Fang and Yao Zheng are very familiar with controlling balance in weightlessness, and they immediately stand up steadily on their military boots, and can maintain a straight posture no matter walking or rising into the air, as if there is an invisible ground that has been clinging to the soles of their feet and rising with them.

Shen Yun had no time to look aside, and in a panic, she saw two blue flames erupting from the heels of her two boots, and then she realized that the so-called tread balancer was actually a simple fuel thruster, and as for what kind of fuel was used, she couldn't tell it.

At this time, the two people over there had already come over, standing beside her on the left and right, and they had the potential to become her personal bodyguards.

Yao Zheng took the initiative to answer her questions: "This preparatory room is specially prepared for the visiting group entering Field C, so the area is not large. Soldiers who actually participate in the training camp have a special channel, and all equipment is distributed as supporting materials when they enlist, so they do not need to use public goods. As for the tread balancers, they have a miniature rocket propulsion system installed on the sole of the shoe, which not only helps you balance in weightlessness, but also propappels you forward at a constant speed in a straight line. It is an indispensable safe travel tool for guests who have never been professionally trained. As for the fighters who can adapt to any tough combat conditions, they can choose to wear them or not. ”

This preparatory room really hasn't created a miracle that can accommodate thousands of troops, but if he can figure out the purpose of its setting, as well as what the tread balancer is about, Shen Yun will be content.

Cao Fang also smiled: "There are two big men to protect you together, even if a big tiger that eats people really pops out of the dark, you won't be afraid, right?" ”

This was clearly aimed at her fear of the dark, Shen Yun heard that her cheeks were feverish, if it weren't for her inconvenience, her head would have been lowered a long time ago. But the white screen wall in front of her suddenly changed color, which immediately attracted her attention.

I saw that the white background of the wall was darkening until it was dark into the night.

But it didn't take long for the darkness to last, and bright spots began to appear on the screen from far and near. Shen Yun didn't see any of the doors in the transition zone open, the step balancer began to carry her forward, and at the same time, a yellow light screen was suspended in front of her not far away, a red dot moved in the light screen, she moved as fast as the red dot moved, and she stopped as soon as the red dot moved.

The content displayed on the light screen is not difficult to understand, it is a panoramic thumbnail of the environment in which the mover is located, and the moving red dot is Shen Yun herself, with the light screen navigation, she will not get lost in the C field.
