Zhang Yaoyang originally thought that the movement of the drone would be very loud, but in fact, there was almost no noise in the whole flight, and only a burst of its own excited 'beep' sound was heard.

"Silent flight?"

A flash of amazement flashed in Zhang Yaoyang's eyes, this kind of technology is obviously not something that the United States can have, and it is obvious that this superb silent flight technology is still the masterpiece of the group of crazy scientists in the hive.

Zhang Yaoyang looked at his wrist and saw that the drone aerial footage began to appear on the remote control, and there was a symbol similar to a battery in the upper right corner, followed by the words 4:43:34, which represented the graphene battery in the aircraft, which could support nearly 5 hours.

Five hours later, the drone will fly in through Zhang Yaoyang's window, land automatically, and wait to recharge and take off again.

After the drone enters the working state, all the creatures seen will be scanned, and then saved to their own database, this program is quite intelligent, using face recognition technology, as long as your information is collected in, then in the future, even if you change your clothes or wear a pair of glasses, the drone will not mistake you for an intruder and kill.

And in the state of defense, the UAV is also divided into three alert levels, of which the three-level alert is the most common cruise mode, in this alert mode, all personnel movements in the cruising area will not trigger an alarm, only if an unknown intruder is found, it will be the first time to warn, and at the same time lock the target, but will not attack the target.

On the other hand, only specific personnel can carry out activities in the warning area, and if a target other than a specific person is found, even in the database, it will issue a warning, but will not attack the target.

The highest level of security is to attack someone other than a specific person as soon as it is detected, regardless of whether the other person is in the database or not.

In addition, there is a custom alert mode, which is flexible enough to handle any patrol mission.

In terms of defense, the UAV shell is made of "Chobham" ceramic composite material, the main component of this ceramic material is silicon carbide, which has the advantages of high hardness and light weight, and the weight is only 50% of steel, and the hardness can reach three times that of steel, and the defense ability against kinetic energy projectiles and ammunition fragments is very strong.

If attacked beyond its defensive capabilities, the shell will absorb a large amount of kinetic energy when it shatters, which will help cushion the impact and will not deform to prevent damage to the components inside.

The middle part of the ceramic shell, as well as a variety of composite materials such as rubber and special resin, can withstand high-intensity electromagnetic interference and prevent the enemy from using electromagnetic interference weapons to cause paralysis of the drone.

And the name of this drone is called "beep drone".

At first, Zhang Yaoyang didn't know the meaning of the name, but now it seems that it is because the drone always makes a "beep" sound, and I don't know if it is the bad taste of the researcher or some other reason.

Just when Zhang Yaoyang was watching with relish, a group of mercenaries suddenly ran out of nowhere, and they raised their heads one by one, looking at the drone with a look of vigilance in their eyes.

"Warning! Weapons were spotted! ”

Almost at the same time, an alarm sounded automatically on Zhang Yaoyang's watch, and the LCD screen of the watch quickly zoomed in, locking on to James who was looking dazed with some red boxes, and the firearm accidentally exposed on his trouser belt.

At the same time, on the LCD screen of the drone, the original smiling face has also become a vigilant expression, and the color has changed from green to yellow, making a "beep" sound.

"Look, there's a gun underneath it!"

At this moment, one of the mercenaries spotted the weapon on the drone, and several mercenaries immediately pulled out their pistols, as if once the drone made any moves, it would shoot it down directly.

"Warning! Five intruders spotted, armed with Beretta M9 semi-automatic pistols, threat rating intermediate, request to fire! ”

When the five people pointed their guns at the drone, Zhang Yaoyang's watch immediately made a loud alarm, and at the same time, the LCD screen of the drone liquid completely turned into a red angry expression, aiming the muzzle of the gun at everyone.

"Request denied." Listening to the warning sent by the drone, Zhang Yaoyang issued a ban order, "Add a few people in front of you to the trust whitelist."

"Beep!" With Zhang Yaoyang's order, the LCD screen on the drone changed back to a green smiling face again.

Zhang Yaoyang looked at the people who were still vigilant, directly pressed the voice button, and said into the microphone on the watch, "James, don't fire, this is the security drone of our factory, and it will act in concert with you in the future." ”

As Zhang Yaoyang's voice came out of the drone, everyone put down their weapons one after another, and James said excitedly, "Boss, it scared me to death, I thought it was the Hindu who came to attack us, but then again, this thing you got must be great to peep into the women's dormitory!" ”

Zhang Yaoyang rolled his eyes, didn't bother to deal with the other party, switched the beep drone to information collection mode, and then closed his eyes again, and after a while, another beep drone of the same model appeared on the floor.

This time, it is not only the drone that appears, but also two devices with complex shapes, just like the base of the drone, Zhang Yaoyang picked up the wire on the device and plugged it into the power socket on the side, which is the charger of the drone, if the power is about to run out, the drone will automatically fly back for charging, eliminating all the processes that need to be manually operated.

"The two drones work in turns, which is enough for the time being." Zhang Yaoyang glanced at the system interface, just two drones, he consumed 600,000 phantom value, fortunately, now the phantom value is gradually getting richer, otherwise this consumption alone is enough for him to feel distressed for several days.

But this is only a special case, and then he will find a way to build a production line for drones, after all, it is impossible for all drones to be embodied with phantom value, this kind of drone is powerful, and there are many places where it can be used in the future.

After solving the problem of emergency response, Zhang Yaoyang finally felt a lot more at ease, in fact, drone cruise is dispensable, after all, the entire factory has a red queen with a camera monitoring, what he mainly lacks is the counterattack force in an emergency, and the appearance of the beep drone can be regarded as making up for this shortcoming.

After that, Zhang Yaoyang began to prepare for the upcoming underground laboratory, he frantically ordered the world's most advanced biological experiment equipment all over the world, if he could not order the finished product, he would use the method of ordering parts, if some parts could not be bought, he would directly manifest them, and these equipment were continuously transported into the underground laboratory to enrich the laboratory warehouse.

And this laboratory, Zhang Yaoyang named it the Hive No. 2 Laboratory, which is different from the Hive Laboratory of the Illusion World, as long as the construction of the Natural Disaster International Technical Service Company on the surface is completed, under the cover of a military base, all the movements of the Hive No. 2 will be covered.
