In the last days, people start an aerospace aircraft carrier

After consideration, Su Xu decided to partially adopt Agent Hill’s suggestion.

Postponed the rescue operation against Zhonghai University, but only for one day.

In addition to the riot of the mutants, the main reason is that he is ready to put the stagnant return line he got today into the city center to see what is happening there.

After making this decision, he immediately sent Kun-type fighters to the campus of Zhonghai University to broadcast the notice.

The S.H.I.E.L.D. Resident Evil Emergency Response Force (SBCS), which was waiting for it, also boarded the fighter plane, and changed from the original rescue mission to camps 1 and 2 respectively for reinforcement.

After arranging these minor matters, Su Xu focused on the matter of putting the stagnant air back line.

Before starting the launch, it is necessary to test the air defense capabilities of the newly emerging mutant creatures with air capabilities in the city center.

Su Xu did not rashly let the space carrier rush up, but first sent a drone for air testing.

When the drone flew above the city center above the gray fog range, it was not attacked.

From this, it can be roughly proved that the enemy cannot attack aircraft at this altitude.

So he ordered: “All drones disperse their positions and begin to descend in height!” ”

The four drones participating in the tests spread out in four directions, forming a square with a side length of 1 km.

Then it slowly sank down into the sea of gray mist at different descent speeds.

Su Xu stood in the combat command center, staring intently at the display screen divided into four parts.

The bottom drone has descended to a height of four thousand meters, and the other three drones above it are one hundred meters higher in turn.

All drones have clear signals and show no signs of interference or attack.

3,500 meters, still normal.

But when the first drone descended three kilometers into the air, the corresponding picture on the screen suddenly went black.

The signal connection to it is also interrupted at the same time.

Immediately after, the other three drones with a height of between 3,100 meters and 3,300 meters also disappeared.

Position sensors mounted on these drones show that the airframe is falling freely. Of course, it is also possible that what fell was just a pile of wreckage.

Su Xu asked: “Can you confirm the type of drone attack?” ”

The synth operator immediately replied in the negative: “Can’t confirm.” ”

Su Xu pondered for a moment and said, “Send four more drones for testing and increase the height difference between each aircraft.” ”

This time, the bottom drone was destroyed when it dropped to 3,600 meters.

The UAV at an altitude of more than 3,900 meters above it diagonally did not escape either.

Only two drones at an altitude of four thousand meters survived.

Su Xu came to a preliminary conclusion.

“The enemy’s defense of the air should be at a normal alert altitude of three thousand meters. Once a vehicle enters this altitude, it will be immediately detected and then attacked by unknown means. ”

“And the ultimate height of air defense is approximately four thousand meters.”

Knowing the height of air defense, it is time to test the density of air defense.

That is, to test how many air targets the opponent can destroy in a certain period of time.

The main reason for testing this is that Su Xu needs to drop the container containing the stagnant return parent body into a low altitude like a bomb, and then release these nanorobots.

If released directly in the air, the nanorobot will be blown away by the air flow and will not be able to spread to the area he wants to monitor.

This time, it was the turn of the Kun-type fighter to throw a special iron can of the same weight and shape as the nanorobot container into the ground at an altitude of five kilometers.

Sensors attached to the tin allow operators in the combat command room to confirm its height and integrity.

……

Zhonghai University.

In another school building near the sixth school building, the survivors hiding there listened with pale faces to the roar outside.

In the past few days, it has never been so “lively” outside during the day.

“It’s over, now it’s full of monsters outside, we can’t get out at all!” At this time, there was no way to rush to the Six Sects before the rescue team came. ”

“I knew that I should have left with Zhan Lan yesterday.”

“Hasty! How did the routine of those monsters suddenly change? ”

“……”

The crowd complained and was annoyed, and the small group was filled with negativity.

The glasses man tried to cheer up his companion: “No one knew if it was safe to set out yesterday, and no one knew that the situation would be like this today.” ”

“Zhan Lan’s choice to leave was originally a gamble, and if she arrived at the Six Sects smoothly, it would only be the right bet this time. But gambler thinking does not bring long-term gains, and our approach is the most rational choice. ”

“Moreover, even if the rescue is missed this time, it is not hopeless. If Zhan Lan is rescued, she will definitely inform the rescue team of our situation, making us a priority target with clear information. ”

But no matter how rational he analyzed, he could not change a fact.

That is, they are trapped here, will miss the upcoming arrival and do not know if there will be the next rescue.

Just as everyone was frustrated, the roar of fighter planes resounded over the campus again.

“The rescue team is here!”

The voice that symbolized hope made everyone even more frustrated at this time.

Then they heard a familiar radio sound.

The content of the broadcast made everyone stunned at first, and then rekindled hope.
