Yeling frowned, what do you mean? Rose Castle follows the security system of Tingyun, which is at the forefront of the world, and so far, the firewall has not been invaded.

Bo Yiren said, Er Shao had an accident a month ago, do you know?

What's the matter? Yeling frowned, hung up Bo Yiren's phone, and directly connected to Yeting Yun's video.

Video connection, coincidentally, Ye Yifan is also there, the video is received by Ye Yifan, happily greeting Yeling, hellyi, big brother, do you miss me?

Yeling waved his hand expressionlessly, with a posture of you dodging, Ye Yifan flashed to the side aggrievedly, and Ye Tingyun appeared in the camera with a smile, big brother, is there something wrong with me?

Why did he run away from you?

We have developed some new products, and if you are interested, you can come and take a look, big brother, what's wrong?

What happened to you last month?

Ye Tingyun was stunned, a trivial matter, and the loss was not big, so I took care of it myself.

Is it related to the security system?

Yes, we have developed a small aircraft, similar to insects, with shooting, video, positioning, tracking, and satellite access to the global biometric system, last month applied to the Department of Defense, connected to the satellite to do an air flight simulation test, very successful, this small aircraft can replace all the tracking products on the market, arms dealers, defense technology.

Why don't I know?

Big brother, this product can't be perfected, I'm doing solar modeling, because the volume is very small, you see Ye Tingyun took a small flying machine from the side and showed it to Ye Ling, the small flying machine is smaller than a fly, it's hard to imagine that this kind of flying machine has such a function against the sky.

Now that no news has broken out, it must still be in the secrecy stage.

This is a major breakthrough in national defense scientific research.

The small flying machine is named after the firefly, but the energy is insufficient, I have done countless experiments, the battery can only support two hours under efficient operation, this is not a perfect product, so I am doing solar modeling, a month ago, there happened to be a batch of products The solar battery was successfully transformed, but the news did not know how to leak out, and the product was stolen.

The loss of the laboratory is not big, so I won't tell you about it, because in addition to this batch of new products, our security system is also being upgraded, and I just finished upgrading yesterday, and I haven't contacted Luther yet.

Does the new security system be able to identify your machine?

Ye Tingyun said, this security system, the code is only known to me, more than 30 engineers each know the code is different, I do not plan to hand over this security system to the Ministry of Defense Science and Technology, so I want to wait for solar modeling to update our security system together.

The highest-end surveillance products are developed by them.

Ye Tingyun will naturally upgrade the security system of his home.

As for the security system of other people's homes, he is not going to bother.

If the security system upgrade is also on the market, this aircraft will be too worthless, and it will be a few years before the national defense technology develops its own security system.

Yeling looked at Ye Tingyun deeply, as if he was enduring something.

Ye Tingyun looked inexplicable, brother, what did I do wrong?

Ye Yifan was overjoyed on the side, second brother, I think you accidentally cheated our eldest brother again.

Ye Tingyun,

Good night to the little fairies!
