At Xinhai International Airport, under the attention of the staff, Qin Tian and his party got out of the car and walked into a plane that had never flown before.

Although it is also called an airplane, the swarthy black plane with a streamlined body is very different from ordinary airplanes when you look at it.

The biggest difference is the lack of flanking and tail flying devices, which makes it difficult to understand how this particular aircraft flew.

Looking at the plane of this shape, Cao Tao, Li Zhen, and Wang Feng refused to get up.

"How do you think this thing flies, it can't run on a few wheels underneath, right?"

"And if you look at this shape, in addition to the size of an airplane, there is a little bit of an airplane. ”

"You three, come up quickly. ”

Seeing that the three of them were still hesitating, Qin Tian didn't bother to explain to them.

"If you can't get up, if you don't get up, we're going to go. ”

Seeing Qin Tian's posture of closing the door, Cao Tao and the three of them panicked, and hurriedly rushed up the stairs.

With a 'bang', the door fell heavily, and the surrounding airport staff gradually faded.

And here, there is only a lone thing like an airplane parked in the square.

Suddenly, a flash of light flickered, and the dark fuselage lit up with a dazzling light, and then I saw the entire flying object slowly detach from the ground, straight towards the sky, and slowly rose into the air.

But soon, the speed of the upper body increased rapidly, and it was still in sight in the blink of an eye, and then disappeared.

On the clouds, a strange flying device, in which three pale young men were clutching the handle next to the seat, their faces were full of panic, although Qin Tian not far away was not so out of shape, but his physical fitness did not allow him to be much better.

If it weren't for the fear that the other three roommates would find it difficult to accept too many things for a while, he would have let Fauber take him directly through the wormhole.

After a while, the faces of several people returned to normal, but before they could recover for long, Fauber announced that it was coming.

"Xiaotian, how can it be so fast?"

Glancing at the three roommates with surprised faces, Qin Tian thought, fortunately, it didn't make you feel more magical, otherwise you might be shocked?

"Do you know what the speed of sound is?"

“340m\/s。 ”

"The speed you just felt was 10 times the speed of sound. ”

Generally speaking, the aircraft is flying at high altitude, where the high altitude refers to 7000-12000 meters, and in this altitude, 1000 meters is an altitude layer, from 7000 to 12000 There are six altitude layers.

China's civil aviation regulations stipulate that below 8400 meters (inclusive), every 300 meters a flight altitude layer, and above 8400 meters (exclusive), every 600 meters is an altitude layer, and the aircraft shall not be less than the specified flight altitude when crossing, relative, and surpassing each other.

In addition, there are some small aircraft activity areas, and the general requirement is below 3000 meters.

In addition, the current record for the highest flight altitude is the X-15A research test aircraft of the United States, which is recorded at 108,000 meters high. ”

"But. ”

Hearing Qin Tian's tone suddenly aggravated, the attention of the three of them suddenly focused.

"We are at an altitude of 250 kilometres, which is in the upper atmosphere. ”

Regardless of the big mouths of the three of them that could be stuffed into pebbles, Qin Tian said immediately.

"The fastest passenger aircraft now flies at Mach 2.2, which is 2.6 times faster than other aircraft, reaching 2,335 km/h, while the fastest fighter jet is the X-43, which has a speed of Mach 9.8 and a speed of 11,500 km/h. Remember, it's all about hours. ”

"And the fastest speed of this craft is, oh, I don't know. ”

"Cut. ”

The three of them made strange noises in unison.

Qin Tian didn't bother to pay attention to these three living treasures, and just asked in the direction of Fu Bo, "Fu Bo, what was the speed of this plane just now." ”

"Mach 10. ”

"Huh?!"

"That's just the initial velocity, you know the speed of light, right?"

"En, you know, isn't it 300,000 km/s, is it possible that this can still fly so fast?"

"Flying so fast? ”

"I'll just say it. ”

"If you fly that fast, you won't be scared to death. ”

In line with Cao Tao's voice, Li Zhen patted his chest.

"I mean, it's impossible to fly so fast because it's faster than the speed of light,"

In an instant, the eyes of the three people stood out and their eyes were glazed.

'Click', 'Click', 'Click'

Three times in a row, three photos came out.

Stuffed into the hands of the three of them, Qin Tian ignored the three living treasures, got up and walked out with Fu Bo.

"Young master, how do the three of them arrange. ”

"That's something I've been hesitating about. ”

The fighters of Tianfu are divided into several levels, the first is the personal guard battalion of the mansion master, the main task is to follow the mansion master to charge, contain the enemy's high-level, the staffing is 500, and personnel will be replenished every time there is a lack of personnel.

The addition of personnel is from a person's loyalty, talent, willpower.

Because the guard battalion is a person who follows the lord to fight, he may come into contact with the back of the lord at any time, and he needs to protect the lord with his life when the lord is injured, loyalty is the most important one, if the loyalty test is not enough, or once the negative change of loyalty is found in the process, the person will be immediately removed from the guard battalion.

A person's realm is not high, but he can be cultivated, and if he has a good talent, the training time is short, and he can join the battle faster.

Willpower is the most critical, thousands of years of vigilance, fighting, fighting, hovering on the edge of life and death at any time, therefore, it is easy to cause some people's willpower to be smoothed out, and some blood will also be cooled, which will leave a loophole for the enemy, so, in every test, we must test whether we can overcome the fear of death in the face of death.

In this way, many people who want to enter the guard camp will be brushed on the last item, and how many people can choose not to retreat at the moment when they know that they will die.

The second is the reserve battalion, which is in the position of preparing to replenish the personnel of the guard battalion who have been damaged by the war at any time, and the selection of this part of the people will be much lower in requirements.

In the past, because of the temporary supplement, the management of this part was relaxed, causing some people to get involved, and the lessons caused were only bloody.

For this reason, the loyalty requirements for personnel in the reserve battalion were also stricter after that year.

Except for these two people who directly belong to the lord of the province, there are other armies.

There is a guard team, dedicated to protecting the human race, this part of the personnel is quite mixed, and the strength of all aspects is uneven, but it is also the largest number, and it is this part of the personnel who have been forming a life defense line in front of the human race to prevent the fire from being extinguished.

The second is the eight armies, each led by a commander, who is responsible for large-scale battles, small-scale annihilation of the enemy, and the clean-up of the remnants of the enemy.

Regarding these three roommates, Qin Tian actually wanted them to supplement the guard camp, but the main problem was their willpower, once they did not have the ability to face death, then going to the most dangerous place would not only be difficult to guarantee their own lives, but more importantly, it would affect the entire team.

"Fauber, let them choose for themselves, let them go wherever they want to go, if, I mean, if they want to participate in the selection of the guard camp or the reserve camp, protect them, don't let them die. ”

"Okay, young master, I see. ”

"So we're going down now?"

"Hmm. ”

Suddenly remembering the experience when he came, Qin Tian hurriedly said, "Fu Bo." ”

As soon as Fu Bo saw Qin Tian's eyes, he knew Qin Tian's thoughts, and with a flicker, he saw a layer of energy covering on Qin Tian's body, and then, the flying machine suddenly fell.
