"Teleport?" This is another fresh word, and Shen Yun is very curious.

Cao Fang replied: "Yes, all the aircraft produced and manufactured by the military industrial units of the Light Continent have reached the level of light speed travel, and they can travel through the universe at will. However, ground aviation is different from aerospace, the geological layer below the earth's crust cannot provide the conditions for traveling at the speed of light, and teleportation has become the main navigation mode of ground spacecraft. However, with each teleportation, the engine system at the tail of the shuttle will emit a large amount of heat, which comes from the antimatter hydrogen fuel, which can reach a high temperature of more than 2,000 degrees Celsius at the initial start, but any object within a radius of 150 meters from the shuttle will melt in an instant. ”

"Antimatter!" Again, Shen Yun heard this term, but this time it came from the Space Force's ground air shuttle!

"You...... Didn't you say that antimatter propulsion is a technology mastered by aliens, and earthlings can't achieve it yet? She asked worriedly.

Cao Fang's answer was: "It is true that the spacecraft of the Light Continent have not yet achieved this propulsion technology, but we have already taken a substantial step - antimatter has been used in the ground shuttle, which is why they can get rid of the fuel tank, have an ultra-small size, and achieve teleportation." ”

After hearing these words, Shen Yun's mood suddenly became indescribably complicated, and for a while, she couldn't even read what she was thinking, and she could no longer find the excitement just now. In order not to arouse Cao Fang's suspicions, she had to put aside the topic of antimatter.

After figuring out the reason why the apron area is huge and the throughput is pitifully small, she has a new question and asks: "If one day, civilians on the ground really move in in a big way, every bomb shelter will face the problem of rapid transfer of personnel." With such a small shuttle capacity, wouldn't it cause a large number of migrants to be stranded and cause riots? ”

Hearing her question, Cao Fang laughed heartily, and after laughing, he replied confidently: "I promise that this kind of riot will not happen, because the optical shuttle, which seems to be the size of a kayak, actually carries ten times the passenger capacity of a Boeing 747 passenger plane."

Compared with the behemoth Boeing 747, the passenger capacity of a small kayak will of course be very different, but it is the "kayak" side that has super capacity? Regarding Cao Fang's words, Shen Yun was skeptical, and whether they were true or false could only be verified later.

Cao Fang also said: "One thing is certain, when the underground light continent is opened to the public on the ground one day, the busyness of these aprons may far exceed the airports, railway stations, long-distance passenger stations, etc. on the ground, and they will never be as quiet as they are now, so even if the apron throughput is so huge, it may not be able to withstand the test of such a huge flow of people." How to solve this problem depends on the CMC's clever measures. ”

"Open to the ground......" Shen Yun's heart tightened, and he instantly thought of the word "open", which meant that the alien invasion had become a fact. At that time, the Continent of Light, which is 400 kilometers deep underground, will become a refuge for human beings, and the once peaceful nature will be completely shattered.

"The Optical Flow Shuttle will be here in four minutes, and it's time for us to change gear." Cao Fang urged, and at the same time showed his wrist hidden in his sleeve. On that wrist, Shen Yun saw a military uniform box that was exactly the same as her birthday present.

Cao Fang motioned for Shen Yun to watch his movements carefully.

I saw him press one palm on the dial and twist it to the left, and then rotate it to the right, without receiving sunlight, and the two thin hands were revealed. Shen Yun couldn't help but think, why had she never tried to split the parts of the watch before?

Then a wonderful change appeared, and she had no time to look around.

After the lid was opened, the hands pointed to the twelve Roman numerals 5 and 12, respectively, and after a while, Cao Fang pressed the switch similar to the pointer adjustment knob.

A pale red aura appeared on his wrist, and then increased in circles at an extremely fast speed, expanding according to his body size, until it enveloped his whole body, enveloping him in a large cloud of red light, and Shen Yun couldn't see him again for a while.

But this invisibility didn't last long, it was like covering his head when wearing a pullover, and before Shen Yun could come back to his senses, Cao Fang's head and hands reappeared, and the original ordinary green military uniform was gone, and now he was wearing a crimson one-piece uniform with no seams visible.

Under the white light, the uniform glowed softly red, and Shen Yun noticed that on Cao Fang's left chest, there was a small badge-like circle, and a bright red national flag was inlaid in the circle. Although the national flag is small, the five stars are dazzling, as full of vitality as if rising from a raging fire.

What Cao Fang is wearing now is a solid-state photon camouflage suit.

The ordinary green military uniform, probably because it was only worn for the "ground people", was not very particular, and it did not reflect the military rank of the wearer. But when he changed into a formal military uniform, everything returned to formality, and Shen Yun could see that five stars were arranged on each of the golden epaulettes on his shoulders, marking his rank as a five-star general. Shen Yun's admiration for him added another layer, and secretly sighed that this person was young, and he was already a marshal.

I don't know if I saw what she was thinking, Cao Fang's expression suddenly fell, and he said with heavy and awe: "If it weren't for General Shen's cultivation, how could I be exceptionally promoted to the deputy commander of the First Army Corps by the Military Commission?" The five-star epaulette, which should have belonged to your father, was set on my shoulder, and the weight was too heavy, and I deserved it. ”

He suddenly made a 180-degree turn in attitude, Shen Yun was at a loss, and he couldn't figure out whether to answer this, so he asked timidly after a while: "Don't you say it's camouflage uniform?" Why is there only one color? ”

"Oh, I'm sorry!" Cao Fang was awakened from his memories and realized that he was far away, so he quickly recovered his face and said, "That's the case, I'll adjust it for you." ”

The glass lid on the box was closed, and Cao Fang dialed the hour hand pointing to 5 in the direction of Dasu, and some irregular color blocks appeared on the uniform. The color patches are large and small, and they are irregularly distributed, and the color is still deepening with the movement of the hands. He fiddled with the second hand again, and the color block began to switch between the seven colors of red, orange, yellow, green, blue, and purple, and the transition was swift and natural, as if he were a chameleon.

"You remember," Cao said, "when the two hands coincide at 12 o'clock, the camouflage uniform will automatically change color with the environment." When it coincides at 6 o'clock, the color needs to be adjusted manually. The other digital areas are fine-tuned and you can decide according to your needs. But in the process of wearing, the glass lid must be tightened, not even a trace of gaps can be left! Because as soon as the color spectrum of the inner core sunlight changes, you can suddenly be exposed to absolute zero, form a solid ice and shatter.

Shen Yun had the courage to feel it on Cao Fang's arm with his fingers, the military uniform looked smooth and shiny, but it felt as rough as snakeskin, which was definitely suitable for the requirements of arduous field combat.

She looked at it carefully for a while, and then asked, "Since the Space Force belongs to the Global Alliance, is everyone's military uniform this dark red?" ”
