After a period of resuscitation, No. 1 regained consciousness and was carried to the rest room by medical staff to rest.

"You are mainly due to the heat and pressure, I have injected you with the corresponding medicine, this medicine will be taken in half an hour, and then I will ask my assistant to stay and observe your situation.

The sky cover suddenly disappeared, the central circle was completely exposed, and a large number of uncomfortable people appeared in the circle, and I had to go back to direct the rescue. Twelve, who is in charge of medical care as the 31st administrator, said.

"I'll leave it to you in the circle, I feel like I'm fine. Go back. Number One took a moment to breathe.

………

"You can't get up yet, take a break." The assistant stops One from getting up.

"Get out of the way, at this time, how can I rest! What about the second wall? What about the Hunters' Guild? No news yet? ”

"I've already sent someone to get in touch. You should be able to come back later. The men reported.

"Isn't the Air Force ready! How long has it been since the accident! ”

"This, still waiting for news over there, after the 'Three Kings' are gone, the start of the aircraft needs to be rewritten......"

(*Central Circle Air Force: After 'that war', only the Central Circle was allowed to possess aerial 'flying' weapons, and no long-range manned aerial vehicles were allowed in the other protective circles.)

The weakness of the protective shield is the top point of the sky shield of all protective circles, and in order to prevent the sky protective shield from being destroyed from the outside, it is forbidden for all protective circles and individuals to have manned aerial vehicles flying at an altitude of more than 500 meters, except for the central circle and the headquarters of the Hunters' Association.

*

The combat-class vehicles owned by the Central Circle and the Hunters' Association as reported at the Twentieth World Conference are:

Central Circle: 23 multi-type bombers, 10 high-altitude patrol aircraft, 30 low-altitude satellite signal transmitters.

Hunter Association: Two fighter-type bombers, six special-shaped special unmanned agent sprayers, and ten hunter-specific signal connection machines.

*

After the Twentieth World Conference, all flying machines were completely abolished, with the exception of the World Governors and the Hunters' Association.

*

At the beginning of the establishment of the protective ring, the average vertical height of the ground of the sky shield was about 600 to 800 meters (except for the nine circles, which was only 400 meters at the beginning of the construction).

But this is not absolute, according to the development of each protective circle, the height of the protective cover can be set by the protective ring itself, of course, the higher the height, the better the technological development in the protective circle.

Prior to the Twenty-fifth World Conference, the heights of the protection rings were reported as 600 metres for the one, three, four, five and seven circles. The second lap is 680 meters. Six laps are 710 meters. Eight laps are 700 meters. Nine laps are 300 meters. The height of the outermost ring of the central ring is 980 meters. Hunters' Association is 820 meters.

Thereinto:

The use of all aircraft in the central circle requires the corresponding agencies to apply for use in advance, which is approved by the 'Three Kings', piloted by special personnel, and no more than three aircraft fly at the same time. Special circumstances that require multiple sorties require the full consent of the 'Three Kings' and the senior management of the Central Circle before they can be used.

The use of bombers by the Hunters' Association requires the purpose, time, location, and pilot's 'biometric credentials' to be reported to the central circle six hours in advance. Sprayers and signals can be used by all Hunters' Guild Thirteen Administrators. ）

"Report! The reprogramming of the aircraft has been completed, how many aircraft will be dispatched? ”

"All! Send them all out for me! If you don't use it at this time, he MD won't have a chance in the future! ”

"Yes!

Forty-eight heavy bombers and sixteen unmanned patrol planes are ready for departure. ”

"The patrol plane goes first, and the others follow, rush to the second wall to support, monitor and report in real time, and everything is subject to my orders." Number One commanded with chest pain.

"Report, manager thirteen sent a report: the central long-range missile has been prepared, I want to ask, do you want to take advantage of the time when the sky shield disappears to remotely support the second wall?"

"Tell them to stay put, and then listen to my orders after the patrol plane sends back the situation on the ground."

"Yes."

……

Outside the second wall, where Ling is:

"What happened? Why did the sky shield suddenly disappear? Zhuge Xun asked.

"I don't know, but the management of the sky shield for the last three walls of the central circle is that the walls and the central circle are carried out at the same time. It's not good, if it goes on like this, the second wall will not be able to support it, since we can't get in from the outside, Kaoru, you go back to the central circle with me first, and then go to the second wall from the central circle. ”

"Wait, Xiaoling, I think it's better to stay out for now." Kate said.

"What do you mean?" Ling doesn't think Kate just wants to stop herself.

"I ......"

Before Kate could speak, Ling noticed that she had received a message on her special license. No one except the Three Kings should know their email address, so who sent this one?

Although all communication signals are now cut off, this card was originally specially made for itself by the World Governor, so it can receive information

Ling plugged her license into the phone she had with her, and through the screen, Ling opened the email.

'ZERO, the situation is extremely urgent, if you can receive this email, please help us regardless of previous suspicions, the central brain 'crashed' for unknown reasons, causing the sky shield of the central circle to disappear, we are stepping up to find the cause, please be sure to assist the second wall to resist the rebels.

If you can get through it safely, on behalf of the Central Circle, I am willing to agree to all your requests! Thirty-one managers stay. ’

"What's wrong?" Zhuge Xun asked.

Ling directly showed the phone screen to Zhuge Xun, and Kate also got up......

"Are you going to ......," Zhuge Xun asked.

Ling's current situation, to be honest, is not suitable to participate in this chaos, but with his character, he will not back down.

"What's that? I didn't expect the rebels to have a hand! Kate said, pointing to the sky.

"Kaoru, is there a way to knock that down?!" Ling saw the military planes that appeared over the rebels and were flying towards the second wall.

"This height ...... I'll try. "Zhuge Xun pinched out a stack of 'blasting talismans'.

"Kaoru and wait!" Ketra lives Zhuge Xun.

"What do you mean?" Ling looked at Kate puzzled.

"Ling, this war is not something we should be involved in. Let's take a look, and you see, on the other side of the second wall, there are also many planes, maybe the central circle itself can solve this matter. ”

Kaitra shook her head at Zhuge Kaoru's hand.

"Could it be...... She? Zhuge Xun suddenly understood what Kate meant.

"Danger!"

An air-dropped bomb exploded not far from the trio. Although Zhuge Xun stretched out the protective enchantment, the three of them were still blown far away.

After that, the explosions came and went, and the outside of the second wall was completely shrouded in smoke from the explosion.

Although the three of them were relatively far away, they could still see what was happening in the sky.

It was supposed that the planes sent by the Central Circle and the planes owned by the rebels were competing with each other in the air, and the planes of the two sides dropped bombs from time to time, although the rebels suffered many casualties, but most of them were alien troops, and ordinary people and mechanical troops had withdrawn behind the alien army.

But the second wall is different, without the protection of the sky cover, several of the bombs dropped by the rebels have exploded inside the wall, and although the number of planes on the rebel side is not as large as that on the second wall, it seems that it can interfere with the flight of the planes on that side, so although the number of planes sent by the central circle is large, it is still a hard battle against the rebel planes.
