Let's go. ”

After talking to Professor Li on the phone, Lin Yu patted Zhao Xiaolu, who had been waiting for a long time, and went out to shop after changing his appearance.

Tired of being crooked for a whole day, until more than six o'clock in the evening, estimating that the experience should have been collected, Lin Yu sent Zhao Xiaolu home, and he politely declined Zhao Jianwu's invitation to have dinner together, and returned to Longteng Mansion alone to check his various belongings.

This video implants a large number of 'advertisements' of the main equipment, but basically it is only a superficial taste, the audience's attention is limited, and too many elements will divide the attention too much and affect the effect, which is a truth that any creative practitioner understands, and the same is true for experience collection.

Needless to say, the protagonist of Survival Diary II is naturally a flying skateboard, followed by a hundred million times of battle suits and three kinds of medicines: self-healing, body strengthening, and nutrition.

【Flying skateboard prototype】

[Grade] LV0: 624320/300

[Introduction]: The flying skateboard made by Longteng Technology Laboratory is equipped with a miniature turbojet engine and attitude control system, with a maximum speed of 120 km/h and a maximum endurance of 10 minutes.

[Evaluation]: Teenager, do you know about the innovative project ropeless bungee jumping?

————————

The production of the flying skateboard did not take much effort, all of them were processed with materials and components available on the market, and the basic appearance is the first appearance in the video, with a turbojet engine and a bulky fuel pack, and the stabilization system and control system are extremely rough.

After all, it only took a little more than a week from production to video shooting, and even if most of the video was a lucid dream scene built with Xiao Ke's assistance, there would be so much time left.

Of course, there are deliberate reasons for this, the flying skateboard is only used by him to obtain plasma propulsion technology and energy technology, there is no need to make the experience demand too high, otherwise he will not want to get flying armor in a short period of time with tens of millions of experience.

"Three hundred points of experience, as expected, it should just be the optimization of the program and materials."

Glancing at the attribute board, Lin Yu casually clicked on the upgrade.

He deliberately made the control program and structure of the flying skateboard relatively rough in order to reduce the need for basic experience.

Different experience zones represent different levels of leveling, and the base experience can be controlled to a certain extent, excluding alternative materials or special cases where the concept is too high.

Take this flying skateboard as an example, if it has been developed perfectly, then it must be upgraded in a more high-tech direction, but if some defects are left, there is a high probability that the next level of upgrade direction is to improve these defects, and the basic experience requirement will be reduced.

This is also a little trick that he has only recently figured out, although it sounds a bit unusual, but it is actually quite practical, after all, the level experience requirement is ten times increasing, and by controlling its base experience, you can grasp the subsequent upgrade range.

It is good to have high potential, but the relative collection of experience will also be a long process, and sometimes it is inevitable to need a little trade-off and control.

【Turbojet Skateboard】

【Level】......

【Introduction】:......

[Evaluation]:......

————————

The blue light flashed, there was no accident, the flying skateboard just optimized the balance control system and slightly increased the endurance and speed, in essence, it is not much different from the flying skateboard developed by modern technology, and it is not even as good as the Milican individual combat system.

It has been upgraded again, this time in terms of engine, not in fact, it is more supercharged technology to become a micro turbofan engine, the speed and thrust have been strengthened, the fuel consumption has been reduced, and in general, the speed and endurance have been improved.

"I hope I don't play with ......"

Before being promoted to the third level, Lin Yu's heart also had a wisp of fluctuation.

The upgrade ability is created out of thin air, and the difficulties of machining accuracy can be completely ignored, and it has no impact on the experience requirements, so it stands to reason that 30,000 points of experience should be able to upgrade the micro chemical rocket engine.

But the prediction is just a prediction, and he is not completely sure, if the third stage fails to upgrade the rocket engine, then the fourth stage wants to plasma propulsion technology, I am afraid it is also a bit hanging.

Upgrade!

Worried, Lin Yu's escalating action did not stop, and the dark blue brilliance gushed out again before it dissipated and wrapped the flying skateboard.

【Batwing Solo Aircraft】

[Grade] LV3: 591020/30w

[Introduction]: The batwing individual aircraft is equipped with a miniature liquid rocket engine and a high-altitude maneuver reaction system, which can theoretically operate in a cosmic vacuum environment, with a theoretical speed of 600 km/h and a theoretical endurance of 1 hour.

[Evaluation]: Theories are just theories, first you have to think about how to send yourself to heaven.

————————

"I thought it would be called a Green Goblin skateboard."

After reading the attributes, Lin Yu finally put his mind at ease.

The reason why a rocket engine is a rocket engine is because its propellant contains an oxidant and a working fluid, and it does not need to be exposed to outside air, so the batwing man-made vehicle has been able to fly in space.

The speed and endurance are also extremely good, the endurance of an hour is more than enough to cope with most situations, and the speed of 600 kilometers per hour is far beyond all kinds of supercars, after all, it is only a micro engine, it is impossible to compare with the real aircraft rocket, and the average person can not bear the 600 kilometers per hour without protective measures.

"Xiao Ke, scan and record the structure, establish a three-dimensional model for archiving, extract the backup control system and balance system, and analyze the propellant composition ......"

The value of the miniature liquid rocket engine was very high, so Lin Yu paused for a moment, recorded various data and took some samples of propellant.

After nearly half an hour of tinkering, he continued to click on the upgrade.

【Bat Wing Aircraft Type II】

[Grade] LV4: 291020/30w

[Introduction]: The second-generation batwing individual aircraft is equipped with plasma propulsion technology and cold nuclear fusion reactor technology, with greatly improved endurance and flexibility, with a maximum speed of 400 km/h.

————————

The brilliance dissipated, and a bat-wing flying skateboard that was exactly the same as in the survival diary II appeared in front of Lin Yu, the original bulky fuel pack had disappeared without a trace, and the 'iron boots' that fixed the legs had also become a concave non-slip striped pedal with only the thickness of the sole.

The speed of the fourth-stage batwing vehicle is reduced by a full third compared to the third-stage speed, but this is also a normal situation, electric propulsion technology is generally high specific impulse and low thrust, and today's small plasma thrusters even have a pitiful few Newtons or even a few tenths of a Newton thrust, and the manned speed of 400 kilometers per hour can already scare those experts who study plasma propulsion technology.

And although the literal attributes are reduced, the implicit enhancement is immeasurable, the biggest advantage of plasma propulsion is the low demand for working fluid and the flexibility and controllability, the air static suspension, subtle attitude adjustment, and high-speed direction change, which are incomparable to chemical rocket thrusters.

After all, flying skateboards are used for combat and low-altitude flight, speed is often not so important, as long as it is qualified, but flexibility is the most indispensable.

What's more, Lin Yu is actually a drunkard, not drinking, all he wants is plasma propulsion technology and miniature nuclear reactor technology.

In fact, the second-generation batwing vehicle gave him a big surprise - a miniature cold nuclear fusion reactor!

It may not be intuitive to say that the cold nuclear fusion reactor is more straightforward, but to put it bluntly, this thing is the same thing as the miniature ark reactor in Iron Man, and there may be differences in the technical implementation, but the essence is the same.

The concept of cold nuclear fusion is somewhat similar to superconducting materials, but it is relative to thermonuclear fusion, usually nuclear fusion requires high temperatures, and cold nuclear fusion can be carried out at low and room temperatures.

Although he secretly rubbed the porcelain in the survival diary II, Lin Yu didn't expect to upgrade this thing, and it would be good to upgrade a high-end nuclear battery.

I'm afraid that most of the 300,000 experience this time will be smashed on this small reactor, and plasma propulsion can be said to be a fluke to this extent.

"What am I? Green Goblin plus Spider-Man hybrid? ”

Unable to study the structure of the batwing aircraft, Lin Yu couldn't wait to step on the skateboard, looked at the venom suit on his body and had a strange thought, then shook his head and threw it out of his mind, started the skateboard and soared indoors.

The plasma thruster is very stable and flexible, just like playing skateboard or balance car, the legs do not need to be fixed at all, the balance control system inside the aircraft will naturally adjust the attitude according to the center of gravity after the center of gravity of the body, and firmly support the body on the skateboard. Just like in the survival diary video, open the window and fly into the night sky outside the building.

", Meteor!"

"Your meteor is on blue fire, it's obviously Gatling!"

"Gatling, I'm Iron Man...... it! the groove! There's really a guy on top of Nima! ”

"It's a prop master! The cliff is the prop master! The big guy really made a flying skateboard! ”

I'm sorry, I've been looking up the information for a long time in order to write it truthfully, and it's late.
