Dong Chen opened the message board and looked at the recent messages, and sure enough, a large number of messages suddenly appeared yesterday.

"Ox X is not a fire series!"

"I was seduced by yesterday's power armor video, and after coming over, I discovered a new world!"

"Road to Powder...... Cattle! ”

"Shocked domestic cattle people!"

"Dereliction of duty! Actually, this is not power armor, this is just a tractor!! ”

"Are the great gods hidden so deeply, usually not showing mountains and water, but I was shocked when I got closer!"

"Dig a pit and dig up a prehistoric alien ruin!"

"Offer your knees, dedicate your knees, dedicate your knees"

"Wow,I always thought that the boss was only posting videos in the post bar.,I didn't expect there to be here.,And it's more than the post bar.,The boss really doesn't say anything.,Is it to be a beautiful man quietly?"

"Hello Director!"

"Hello Director, please bring a good seat to the bureau as well!"

There are really a lot of various messages from Balabala, well, it's worth celebrating, so let's add a braised egg to dinner.

After closing the web page, I started to upgrade the operating system of the micro machine and the 3D printer with my computer.

That's when he felt like he needed more computers, this one wasn't enough at all, and it was a laptop.

Maybe you can combine the advantages of the two worlds and make a few "high-configuration" computers.

But will it be suddenly "checked water meter""Ah, probably not, how can a good person be "checked water meter"?,Do I also have the victim paranoia of the protagonist of the novel?

It seems that it is better to learn the technology well, no matter what you find, it is said that it was made by yourself, if you don't believe it, just make one in front of you, and then look at your confused face, haha!

After upgrading the operating system, I saw that it was already past eleven o'clock, picked up my broken computer and walked towards the computer repair shop next door.

"Brother Li, I brought the computer, oh, I'll give it to you."

Li Dong looked at the miserable computer that was placed on the table.

"Hey, it's really split, it's exactly the same as those hey."

"I'll see, I'll see, tsk, tsk, miserable!"

"Hey, you're the worst I feel, are you the closest to lightning, you've been split like this!"

I'll go! Brother Li, you are the reincarnation of Sherlock Holmes!

"Ahem, Brother Li, do you still have the value of recycling, how much can you sell for rags."

Li Dong also saw the traces of the burning, and said casually, he didn't know Dong Chen's mental activities, and when he heard Dong Chen ask, he replied: "That's it, I'll show you." ”

"Well, this one can still be used, this one is scrapped, this one is scrapped, this one is scrapped...... also scrapped...... Scrapped...... Finish. ”

"You bought it for more than 8,000, right? Now it is estimated that it is worth more than 800. ”

When Dong Chen heard this, there were still eight hundred left, which was not bad, and the month's meal money came out again.

"It's good to have some left, I thought there was nothing left, not bad, then I'll give it to you."

"Okay, I'll transfer you later."

"Okay, then you're busy, I'll go."

After Dong Chen went back, he ordered some computer parts and some monitors on the Internet, yes, not a monitor, but some, Dong Chen planned to make his studio higher, more monitors, more computers, and more sense of technology.

In the next few days, Dong Chen wanted to see the beautiful Miss Zhang Yunxue again every day, and contact others, but unfortunately he didn't see him for several days.

Therefore, Dong Chen has been struggling for his flying skateboard for the past few days, studying in the radiation world, and looking for information in the arc jet power laboratory.

It's a pity that although there are a lot of things learned in the auxiliary learning system, it is only some relatively basic knowledge, just like the school, there are a lot of things taught, very comprehensive, and all aspects are involved, but none of them are outstanding.

Let's just say that the flying skateboard that Dong Chen is doing now is in the basic knowledge and historical changes involved in this aspect in the books, but it is in the history textbooks, so Dong Chen has to go to the arc jet power laboratory to collect information, and after collecting the information, it cannot be transmitted to the learning assistance system to accelerate learning, because the video, audio, pictures and texts there are specially made, so that they can be combined with microwave stimulation for rapid memory and learning.

Those who find technical materials can only learn slowly by themselves, and learning is learning, but they can't be copied to the flying skateboard, because it is too black technology, and it needs to be weakened, or find some old technology that radiates the world to transform.

In this way, after more than a week in the real world, plus the radiation world forgot to calculate how many days, Dong Chen's flying skateboard prototype was built.

The main body of the flying skateboard consists of a five-liter fuel tank, two miniature turbofan engines that provide the main power, four miniature vector nozzles that adjust the direction and maintain balance, and a miniature flight master computer, in addition to a single-handed remote controller, which can not only control the aircraft, but also display fuel level and flight conditions.

All the parts are integrated into one, and there is no need to carry a cumbersome fuel tank backpack separately, so the entire flight skateboard is still relatively small, and after filling up the fuel, the weight is less than thirteen kilograms, but the fuel tank is indeed a bit small, and after filling up aviation kerosene, the theoretical flight time is only between three minutes and three minutes and thirty seconds.

The design speed of the flying skateboard is up to 100 km/h, the maximum take-off weight is 85 kilograms, and the maximum flight altitude is quite high, 4,000 meters, but this three-minute flight time, if you want to fly 4,000 meters, you are looking for death.

It's not that Dong Chen can't build a flying skateboard that flies faster, has a larger take-off weight, has a higher altitude and has a longer flight time, but this is not the first generation of aircraft, how can you get a Niu X without upgrades!

……………………

In the footage of the camera on the table, Dong Chen took two safety ropes hanging from the roof and hung them on himself, and then stepped into the card slot on the flying skateboard in turn, and with the sound of "click" mechanical closing, the safety fixture of the flying skateboard fixed Dong Chen's ankle below the part.

The reason why even the ankles are fixed is because I am afraid that someone's shoes will come loose, so as not to be in danger because of this, which is too funny.

"Whew~"

Dong Chen was still a little nervous.

"The first test of the flying skateboard, the first item, the test goal: ignition."

"Three, two, one, start!"

"Hush~hum-"

Listening to the sound of the turbofan engine truthfully, Dong Chen breathed a sigh of relief, fortunately, it was a success, if there was a problem at the beginning, it would be bad.

"The electric start device responded well, there was no delay, and the test was completed."

"The first test of the flying skateboard, the second item, the test goal: liftoff."

"Buzz ~ Buzz ~ Buzz ~ Ming-" As the beep of the turbofan engine became more and more sharp, the flying skateboard slowly flew up.

"Wow~, haha!"

"Ness!!"

"The lift-off process is good, the fuel supply is normal, and the test is complete."

"The first test of the flying skateboard, the third item, the test target: flight steering."

“…………”

"There is a delay in the steering, the No. 3 vector nozzle is unstable, and the detection is complete."

"Flying skateboarding first ......, fourth ......"

“…………”

"Whew~~"

"After all the tests are completed, it seems that there are still a lot of problems that need to be modified."

"Sure enough, it's impossible to do it all at once."
