"You should also go and rest. I ate too much and won't be able to sleep for a while. I want to practice my air-bending skills."
Xu Yi persuaded Ling Yue to take a rest. He still didn't trust the Iron Shou Gang, so he wanted to find a chance to take a look around.
After all, he has a Jingshen drone in his hand, and he can use its infrared lens to find nearby targets and see if anyone is hiding nearby.
Ling Yue nodded obediently, then took Ling Shuang and left together.
The top brass of the Seven Killers all live in the townhouse.
Ordinary soldiers were housed in the dormitories of the original steel plant.
Those dormitories were converted into two-person rooms, and the extra iron beds were moved out and placed in the two large warehouses that were cleared yesterday.
Currently, survivors from the city center are being housed in two large warehouses.
The women were placed alone in a dormitory building with slightly better conditions, with eight people sharing a room.
There are even security teams patrolling the place, so there isn't much of a safety problem.
The Seven Killers were still able to maintain good public order and did not bully ordinary people.
Xu Yi walked around and found that everyone was settled well.
Of course, there must be many ordinary people who are not happy.
Some officials and some former wealthy businessmen are very dissatisfied with their current situation and want to restore their status and life before the end of the world.
Xu Yi discovered that some of them were wooing others and seemed to have made some promise to them.
After Xu Yi found out, he asked the security team to keep an eye on these people.
Now, he is in no hurry to deal with these people.
Because there is still a need for a large number of laborers, and there are many things they need to do.
As long as the stability is not affected, Xu Yi has no plans to touch them for the time being.
There must be some ghosts and monsters in the crowd, and it's good to keep them together. When they need to be dealt with, they can be dealt with in one pot, without having to bother to screen them one by one.
After walking around in a circle, Xu Yi reached the roof of a factory building.
The location here is relatively high and the view is better.
Xu Yi took out the box of his Jingshen drone and opened its box.
Picking up the battery of the Jingshen drone, Xu Yi immediately had the idea of upgrading it.
[500 survival points can be used to upgrade the battery to a micro graphene super battery. After the upgrade, the battery capacity will be increased by 4 times. 】
[1500 survival points can be used to upgrade the battery to a radioisotope battery. After the upgrade, the battery can last for 1 year. 】
There are two options, one is a super battery and the other is a nuclear battery.
Xu Yi hesitated for a moment, then chose the former.
Because he wants to upgrade two batteries. If it costs 1,500 points, it will be too expensive and he cannot afford the upgrade.
"Survival Points-500"
"Survival Points-500"
The appearance of the two batteries has not changed much, but its power capacity has increased four times.
Originally, its battery can allow Jingshen to fly for 4 hours. After the upgrade, it can allow Jingshen to fly for at least 16 hours, or even longer.
Xu Yi spent 1,000 points just to upgrade the battery.
However, Xu Yi was not satisfied yet.
Therefore, after Xu Yi installed the battery, he focused on the fuselage.
[You can use 2000 survival points to upgrade the drone to visual stealth effect. After the upgrade, the drone will be invisible to the naked eye. 】
"Upgrade!" Xu Yi chose to upgrade without hesitation.
"Survival Point-2000"
In this way, it doesn't have to worry about being discovered by anyone, not even other mutant birds.
According to the intelligence of the military department, there are many bird-like mutant beasts in the sky. They are very aggressive and even fighter jets cannot avoid their attacks.
In order for the drone to be used safely, it is very necessary to be invisible to the naked eye.
Although 2,000 points is quite expensive, Xu Yi thinks it is still a good deal since it can achieve this step.
Even with the technology in this world, there is no way to do this.
Even if it is 20,000 points, Xu Yi thinks it is reasonable.
After having the stealth system, Xu Yi will upgrade its communication distance.
In this way, he can investigate everything around him at will.
[5000 survival points can be used to increase the maximum map transfer distance of the drone to 35 kilometers. 】
"So expensive?"
Outrageous!
The original image transmission distance was 20 kilometers, but now it has only increased to 15 kilometers. It actually requires 5,000 survival points, which is more than twice as expensive as installing a stealth system.
I can’t afford it, I really can’t afford it!
Xu Yi thought for a while and gave up on other upgrades.
"Now that you are no longer the original drone, your appearance has changed, so let's call you Yin Kong."
After launching Yin Kong, Xu Yi found some changes in his remote control interface.
With an invisible status button, you can turn on the invisibility function with just one click.
In addition, the battery life shown above is 18 hours.
"How come the maximum image transmission distance has been shortened so much, to 10 kilometers?"
Xu Yi found that the image transmission distance was directly shortened by half.
Xu Yi frowned, thinking that it must not be caused by upgrading the invisibility function.
"Is it because of the virus?"
Xu Yi thought that the military was losing control of the satellites, so was the shortened image transmission distance of his invisible drone also because of the 'virus'?
Otherwise, there is no way to explain why the image transmission distance will be shortened.
Now, he understands why it is so expensive to increase the image transmission distance to 35 kilometers.
After activating Yin Kong's stealth function, Xu Yi found that it gradually became transparent.
"This should use some kind of projection technology to achieve the purpose of invisibility. No wonder it is invisible to the naked eye."
Xu Yi now knows why it is cheaper, because this technology is not particularly difficult. The technology in this world can also do it, but it cannot be so perfect.
The traffic lights can no longer be seen, which is really impressive.
Controlling Yin Kong, Xu Yi let it fly high into the sky, and then began to look around.
After enabling the thermal infrared lens, Xu Yi clearly saw the situation outside.
Infected people appear to be gray and black in patches, and cannot be seen clearly.
However, Xu Yi saw two people on the balcony of a building.
"Only two people left?"
That building is in an old community where Xu Yi and the others once stayed, so Xu Yi is almost certain that these two people are from the Iron Hand Gang.
"I don't know if anyone else is hiding in the house."
"If there are only two people, we can kill them at night. Enemies, if you kill one, you will lose one."
If there were only two of them, it wouldn't be a problem for Xu Yi to take Ling Yue, Lu Ran, and Qin Li and kill them directly.
After thinking about it, Xu Yi controlled Yin Kong and flew back.
By upgrading it with another function, you can test out how many people there are on the other side.
