The two-day flying carnival has finally come to an end, and if you want to ask the most memorable moment in this carnival, I think when Dong Chen stepped on the flying skateboard and soared into the sky, people may not forget it for a long time.

Due to Dong Chen's amazing flight display, the popularity of personal aircraft has continued to rise in China, and Dong Chen's fame has also continued to rise.

Lin Dajiang also obtained the production and sales rights of the first generation of Black Phantom flying skateboards.

As mentioned in the previous chapter, Lin Dajiang is a chairman, and he has a machinery factory in Haishi, which is a manufacturing factory specializing in making model props, movie props models, aircraft models, tank models, etc.

From the business of the factory, it can be seen that Lin Dajiang is an extremely interesting person, the two met and became familiar with each other at some parties and exhibitions, and after understanding, they became friends with the same smell.

The two have cooperated a lot of times, and this time Dong Chen still asked for 50% of the profits, and he didn't care about it.

Dong Chen feels that although the first-generation flying skateboard is amazing, the flight time is still too short, and the price will be very expensive.

The others are okay, but Liu Changfeng is too annoying, first complained that Dong Chen went too early, and when they went, Dong Chen had already taken off, and he had already flown very high.

They only saw that people were looking into the sky, and it wasn't until Dong Chen lowered some altitude and started to maneuver that they saw someone in the sky.

Watching the windy flying skateboard shuttling back and forth in the sky, several people were dumbfounded, and only after the pilot took off his helmet did they see that it was Dong Chen.

They hurriedly squeezed through the cheers and whistles of the crowd, and also greeted Dong Chen excitedly, and then, Dong Chen was entangled by Liu Changfeng and them.

Liu Changfeng really didn't talk about the toy power armor, he had to buy this prototype with a dead face, Dong Chen told him that the new product would be on the market soon, and he wanted to sell as much as he wanted, but this product had to buy this prototype first, which was annoying.

In the end, on the second day of the carnival, I was annoyed for another day, I really couldn't do it, I could only give it to him, I really didn't want to be annoyed by him, and I had to make a new one.

Hurry up and give the flying skateboard to Liu Changfeng, and it's time to prepare for travel.

Sure enough, the seaside and ancient buildings are too attractive for college students, especially for a group of college students who are about to graduate.

Dong Chen's class has a total of 20 people, and then the typical liberal arts class structure occupies the side of art, so the ratio of men to women is 8:12, of which seventeen people chose to explore Taihang Mountain, two people chose the seaside, and only one person chose to appreciate ancient buildings.

The class group has been talked about.,How can there be a cold look before.,Say what's there.,Some give advice.,Some say precautions.,Some say what to buy.,Information refresh that's called a fast.,If you turn on the prompt sound,The "Di Di Di" sound can definitely blow up!

However, some basic wilderness exploration equipment such as sleeping bags, tents, ropes, and compasses have been bought, and they are still the sellers contacted by Dong Chen.

There's no way, who let Dong Chen know more people, after buying it, he is shipping it here, which is much cheaper than other places.

I also bought some drugs or something.,Because of the limited class funds.,So I can only buy some basic things.,And the list of items has been posted in the group.,If you feel that you're still missing something, you can bring it up with the class cadres.,If it's a necessity, you can buy it collectively.,If not, then you can only buy it yourself.。

Dong Chen and the others looked at this final list, and felt that it was okay, basically the same, and it should be redundant to buy again, but each person needs to carry a little bit of these things into the mountain.

"How do you feel, everything is complete, right?"

Dong Chen asked Li Xiang about them.

"Well, the main thing is that we haven't been in the mountains before, so I don't know what to buy, but I feel like it's almost there, it's just ......"

"What's it?"

"None of these things are weapons!"

"yes, no weapons!"

"I don't have a weapon, I don't know the bottom of my heart."

"Hmm~, that's a question, I'll ask the squad leader."

As he spoke, Dong Chen contacted Wang Fang and asked about the weapon.

"Senior squad leader, should we buy some weapons for self-defense?"

"Weapons? This is forbidden by the state, and it's not easy for us to buy this, let's not go to those dangerous places, just play in some slightly marginal places for a few days, there's no need to bring weapons, right? ”

Wang Fang replied with some hesitation.

"Oh, that's it, then if we bring it ourselves, it's okay, as long as we don't let the police see it, by the way, how are we going?"

"I don't know about this, I don't study law, we will charter a bus directly to the foot of Taihang Mountain, which is a free natural scenic spot, and then after getting off, we will go directly into the mountain from its place."

"OK, chartered car, squad leader, then let's bring some, be prepared, I'll go talk to other boys."

"Okay, actually, I also feel like it's okay to bring some self-defense."

ended the chat with Wang Fang and told the roommates about the matter, and the roommates were quite excited.

"Bring it, bring it, the dagger I bought before is finally used!"

"Come on, your dagger is not sharp, there is a hair!"

"What's not there to open the blade, Brother Dong can open the blade! Hey! ”

"Hey, then my craft knife can be used too!"

"Let's go to the deep mountains and mountains, how can we run into the police, right, haha!"

"Okay, if you want to cut it, go to me after class tomorrow, I'll cut it for you, and I'll go and inform the animals in the other dormitory."

After informing the boys in the other dormitory, they chatted for a while and then went to sleep.

………………

There was nothing to say all night, and the next morning, Dong Chen skipped class again, and he went to the Radiation World for a period of time, specifically upgrading and transforming the first-generation flying skateboard technology, and manufacturing the second-generation flying skateboard.

The speed of the second-generation flying skateboard has increased from 100 km/h to 120 km/h, and the flight altitude has not changed, still 4,000 meters.

The biggest change is the flight time, the second generation of flying skateboard uses a new structure of micro turbofan engine, which can greatly improve the energy utilization rate of existing aviation kerosene, but this special structure can only be used for micro turbofan engines, can not be used to manufacture large engines, so it has not received much attention in the radiation world, which is still Dong Chen turned over in the data reserve room of the arc jet power laboratory.

However, this miniature turbofan engine, the power system used to make the second-generation flying skateboard, is just right, and the flight time of the flying skateboard has been increased from three minutes to forty minutes, so that the flying skateboard has developed by leaps and bounds, and it has become practical in a real sense.

At the same time, the structure of the second-generation flying skateboard has been simplified, so that the volume of the flying skateboard is reduced by a quarter compared with the first-generation board, and the weight is also reduced by one kilogram, making it more convenient to carry.

Moreover, the second-generation flight skateboard also added a silencing module, because the noise of the first generation was really a bit loud, so Dong Chen added a silocene module to the second-generation to greatly reduce the screaming sound of the turbofan engine.

Therefore, the second-generation flying skateboard is not a level of things at all compared to the first-generation flying skateboard
