10,000 meters above the sky, at the junction of the troposphere and stratosphere.

Countless overlapping clouds make this layer like a white continent, as far as the eye can see, and the sunlight spreads on the clouds, which makes this continent dreamy.

Shout~

The sound of breaking through the air echoed through the area, and a fighter jet emerged from the clouds.

The fighter plane that broke through the clouds climbed very quickly, but in the next second, from the cloud where the fighter flew out just now, something seemed to rush out! Closely followed the fighter.

In the fighter plane, above the pilot position in the cabin, the pilot in the front seat was wearing a helmet and couldn't see any expression clearly, and judging from the stability of his hands controlling the joystick, his state of mind was very relaxed, but the one in the back seat of him didn't look so relaxed.

Her helmet mask was not pulled down, and she looked at the electronic screen in front of her, the data on which was constantly updated.

Bangbang.

There were a few knocking sounds from the glass next to her, and she immediately looked up, and there was a figure outside the cockpit that was on par with the combat power, and the two white wings were extremely dazzling under the reflection of the eyes, which were the frost.

"Sister Hu, I'm ready."

Although Dr. Hu, who was sitting in the back cabin of this fighter plane, could only see the shape of Ning Shuang's mouth clearly, the sound of Ning Shuang came from the headset.

"Let's get started."

Doctor Hu tapped on her electronic screen, she needed to collect all the data on the changes in her body after the frost was waiting.

Frost was recognized by the action, and the wings behind her flapped even more violently, and in front of her, a faint white barrier formed.

Ning Shuang felt a huge resistance that began to block the increase in her speed, this feeling she had encountered a few times before, and Doctor Hu told her that this was the sound barrier.

The resistance is getting stronger and stronger, and the top speed of the first few frosts is only the critical point that can reach the sound barrier.

This is the eighth time.

Is that all? Tomorrow will be the joint training of the five countries, which means that there may not be any opportunity to conduct this kind of fastest training for a period of time in the next period of time.

"Frost, don't force it, there are still ten minutes left, and this training is coming to an end."

Doctor Hu was admonishing the condensation, and the condensation had been tried several times, each time it was very reluctant, and the index on his body fluctuated greatly, which made Doctor Hu have to worry.

"This kid's personality is too strong, even if he is a man, he doesn't fight like this."

Looking at the data on the electronic screen that the frost had reached the early warning index, Dr. Hu was ready to take coercive measures.

"Condensation."

It's just that before Dr. Hu's words were spoken, only a crazy alarm sounded from the electronic screen in front of him, and a huge sonic boom sounded from the headset.

"Hehe, that little guy has succeeded, hold on, I'm going to keep up with her."

The voice of the pilot in front of me was heard in the headset.

Doctor Hu quickly sat down and put down his mask.

The fighter accelerated wildly, and it also made a sound boom, breaking through the sound barrier and catching up with the frost.

So that's it!

When the condensation frost is flying, the physical energy-like true qi will automatically cover the whole body to help the condensation resist the low temperature and strong wind resistance at high altitude, just now when the condensation frost has never been able to solve the speed problem, she is constantly thinking about how to go one step faster.

When she saw the bow of the fighter, she suddenly remembered that the human body was not always suitable for flying, so she increased the output of the true qi in her body, forming a cone to wrap herself, and sure enough, she directly broke through the sound barrier.

However, supersonic flight also puts a lot of burden on the condensation, maintaining such a speed and the conical protective shield outside the body makes the energy in the condensation body consume like flowing water, which is why Dr. Hu's electronic screen warns.

After only a minute of flight, Frost had to withdraw from the supersonic flight and regain her strength suspended in mid-air, barely holding her wings.

It's a bit too scary.

At this time, the fighter planes also arrived and circled around the frost.

"How are you feeling?"

Doctor Hu's eager voice sounded in the frost headset.

"It's okay, it's just a bit expensive."

"It's okay, the data shows that the energy in your body is at a low point in an instant, return to the base at a speed, and I'll take you for a detailed physical examination."

"Okay."

Frost flew to the fuselage, followed by the fighter, and Frost returned to the base.

"Hurry up and go with me to the recovery pod."

"Sister Hu, it's really nothing, I'm fine now!"

"No, hurry up."

Doctor Hu was about to leave the tarmac with Ning Shuang directly, but a soldier came to Ning Shuang.

"Codename Angel, Instructor Li asked you to go to the No. 3 martial arts training ground on the 2nd floor as soon as you come back."

"Understood!"

Giving the soldier a salute back, Ning Shuang glanced at Doctor Hu.

"Sister Hu, this?"

"Hurry to my medical office when the matter is done."

Instructor Li has an order, and of course Doctor Hu can't stop it.

"Okay!"

For the medical office that was about to strip naked at every turn, the cream was still a little resistant, although she had taken it off many times.

Hurried to the martial arts training ground.

In the martial arts training ground, except for her, all seven people arrived, and Instructor Li was also present.

"Assemble."

said that it was a gathering, but in fact, it was the return of frost.

When Frost returned to the team, Instructor Li began to speak.

"Tomorrow you are going to participate in the five-nation joint training, I have also seen your efforts in the past four months, and here I have to praise you, you are quite outstanding."

Everyone didn't answer, first raised and then suppressed, this is a cliché that everyone knows, and sure enough.

"However, you must know that there is no shortage of elites in other countries, and among the students this time, we Huaxia are actually still the relatively inferior side."

Everyone's faces were not very happy, this is not compared, how can the instructor say that they are not as good as other national students.

"Report!"

Instructor Li looked at Gao Shiqing who shouted the report and nodded.

"Speak."

"Why do you say that we are not as good as students from other countries, I don't think we are bad!"

Instructor Li looked at everyone after listening to Gao Shiqing's answer.

"Do you think so?"

There was silence, but everyone's arrogant eyes told Instructor Li their answer.

"Okay, everyone immediately go to the training plaza on the first floor."

"Yes!"

"Xiao Leng, Yan Ningshuang, you two wait a minute."

The two of them, who were just about to walk with the others, stopped and stood in front of Instructor Li again.

"How was the team after the order was given to the two of you to become captains, and how did the other team members react?"

"Report to the instructor, there is no special reaction, the team members have no objection to the two of us becoming captains, they are quite supportive of us."

Xiao Leng answered Instructor Li's question.

"That's good."

"Instructor, can I ask you something?"

Ning Shuang suddenly asked beside him.

"What's the matter?"

"Why did you make me the vice-captain?"

After listening to the condensation question, Instructor Li pondered for a moment.

"Want to hear it?"

"Yes."

"A woman's body, a man's heart."

Ning Shuang's heart chuckled, could it be that he was discovered? No, no, you must behave like a normal girl now, how do normal girls behave at this time? I have to think about it.

By the way, normal girls will definitely shout annoyance at this time and then run away angrily.

It has always been a good habit to do it when you think of it, and she snorted.

"You're annoying!"

After speaking, he ran out of the room directly and went to the training square, leaving only Xiao Leng and Instructor Li, who were in the martial arts training ground, stunned.

"That was Yan Ningshuang just now?"

Xiao Leng muttered to himself, how could he feel so disobedient.

"Hehe, this little girl is obviously very accepting in her heart, but she wants to pretend to be annoying, interesting."

Instructor Li's eyes are quite vicious, and he has always been very accurate in seeing people, and Ning Shuang's heart was immediately seen through by him.

"Instructor, it's definitely not for this reason that you made her the vice captain."

Xiao Leng and the instructor chatted while walking.

"Of course not, after all, the team has five men and three women, nearly half, Yan Ningshuang, this girl is stronger than the other two, and she is also very talented, and after all, she is a girl, so she must be more delicate."

"That's right."

Xiao Leng sighed.
