The sudden reward is really a bit inexplicable, the reward is still very large, which is equivalent to a reward of 4999, in fact, it is not just a reward of points, listen to the tone, the qualification for exchange is also quite valuable, but this reward is really a bit of a pain for Li Yunfei, because all his points are only 4050 points in total. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

In the dream, listening to the name is a very awesome thing, a mortal article costs tens of thousands of points, even if a five-fold discount is given, and 5,000 points are given to the exercises, the system uncle is still so stingy.

Fortunately, this exchange qualification is not changed immediately, and it is okay to exchange it after making up enough points, so find a way to get more points, and quickly replace this thing when you save enough points, as long as you exchange it, it is equivalent to earning 4999 for nothing.

I don't know how awesome this exercise is, but the price of 50 points for basic internal strength, this 10,000 points, the gap is so big, it must be an excellent thing, as for the mortal chapter, maybe in the eyes of the system, the immortals are all mortals, and even the immortals are mortals.

Li Yunfei counted the things stored in his storage space, there are still some things that can be exchanged for points, such as the grapes, such as the blood worms, such as the refining body fluids and the corrosive liquid extracted from the cockroaches, if you sell all these things, the total number can really stink a thousand points.

“…… Forget it, it's better to wait for the new grapes to be fully ripe and picked, and it's not too late to sell them after testing the efficacy, in case the new grapes don't have the longevity effect, the life extension effect is powerful and the spirit fruit is sold all the gains! After thinking about it for a long time, Li Yunfei finally stopped the urge to sell everything in exchange for divine skills.

……

After a long period of experimentation and modification, that set of flying armor was finally finalized, and there were many changes.

First of all, the four thrusters on the feet were improved, and the maximum thrust was increased by 200%, but the thrusters were not much larger, and the volume and weight were only 50% higher than the first generation.

The maximum thrust generated by one thruster is 220 kilograms, and four together can provide 880 kilograms of thrust, plus 110 kilograms of thrust on each of the hands, so the ultimate thrust is 1 ton, minus Li Yunfei plus the weight of the equipment, you can also drag a ton of things and fly away.

This is the maximum weight that Li Yunfei can barely control freely, if it is heavy, the body will be very uncomfortable, although there is technology to add a power system to the armor, which can increase the body's bearing limit by dozens or hundreds of times.

However, once the power assistance system is added, then the weight of the armor will increase many times, and the flexibility will be greatly reduced, no matter how good the power armor is, it will always be inferior to Li Yunfei's own agility that surpasses ordinary people several times, it is really not cost-effective, Li Yunfei's main purpose for this armor is to wear it in ordinary times, if it is made like a machine gunner power armor that weighs several tons, it will be too inconvenient.

The four thrusters on the shoulders, chest, and back have not changed, and there is that thing, not for super-maneuverability, but for the sake of making it easier when flying in peacetime. As for the maneuverability of the orbit change, in fact, it is more convenient to complete it directly with hands and feet, which is the conclusion reached after continuous testing in the past few days. For example, if you want to decelerate quickly, you can do a backflip and do a 180-degree reversal to complete it, and use the most powerful thruster of the foot to quickly slow down, and you don't need to use other thrusters to complete it.

The energy battery has also been tripled, some aerodynamics have been modified, the radar system has been strengthened, and a new shooting has been added, a pair of small wings that can be freely popped and retracted, which can greatly improve flight stability.

The armor was coated with radar wave stealth material, although it didn't have the ability to directly make the armor in flight achieve the effect of visual stealth, but it could be used in front of radar stealth. It is impossible to maintain the stealth force field in the flying state, and the movement is too loud to destroy the stealth force field, whether it is borrowing thrusters or using wind control techniques.

The weight of the third-generation flight armor is 35 kg, the instantaneous maximum power output of all propellers in the hands and feet, the ultimate acceleration of take-off is 110 m/s, and the maximum overload on the body is equivalent to 11G. Theoretically, it only takes one second to accelerate from a forbidden state to a speed of 420 km/h.

The ultimate flight speed is five times the speed of sound, but that is only a very short period of time to fly, and the fastest flight of long-term cruise is still three times the speed of sound, not because the thrust is not good, but because the thermal barrier formed by air friction cannot be solved.

At five times the speed of sound, it only takes three minutes for the surface temperature of the armor to soar to thousands of degrees......

The 14-hour continuous flight spanned 50,000 kilometers (the circumference of the planet is exactly 50,000 kilometers), successfully completed the round-the-world flight, everything in the flight armor is very reliable, has undergone various bad weather tests, safe and reliable, the superconducting battery capacity is still 65%, and the battery capacity is completely sufficient......

When I returned to the periphery of the base, I saw from a distance that there was a long-awaited Nova standing in the square of the central station of the base, and a few other robots.

Flying around the world is really nothing, and Nova firmly believes that Li Yunfei will not have an accident, but when she watched Li Yunfei go out, she was still worried that he would never return, so Duo Tan was still a little restless. I really want to accompany Li Yunfei to the round-the-world flight test, but her flight armor is not ready, and even if it is done, she can't control supersonic flight now, so she doesn't dare to make any special requests......

"Congratulations on the successful completion of the 100,000-mile ultra-long-distance flight test!"

"Well, don't congratulate, eat first, you're hungry too, sit down and eat together." Li Yunfei directly took out a large amount of food and ate it directly.

This time, in order to verify the limit attributes, he has been flying, but he has been flying at three times the speed of sound for more than ten hours, and it is impossible to open the mask to eat, otherwise the air pressure is absolutely deadly, so he can only endure it.

"Sir, in fact, this powerful thruster can also be equipped with the power armor of the machine gunner, so that the robot can have the ability to fly, which can improve the powerful and improve mobility!" Xiao Wei served tea and water to the boss on the side, and he also hoped that his robot army could be super mobile.

Xiao Wei is just artificial intelligence, although it looks very much like a human, in fact, there is no essential change, everything is the result of program simulation, so for Xiao Wei, it is all his 'pursuit' to make the robot work more efficiently, and the movement efficiency of the flying robot must be higher.

"Well, although your proposal is very good, but this matter will be talked about later, now I don't have the ability to change the control system of the machine gunner, after the addition of thrusters, it will be necessary to completely upgrade the power armor, control system, stability system, and energy system, which is not possible now...... But I can give you a robot that weighs less than a ton, and make a flight system, and that's more! ”

"Thank you, sir, you are the best in the world, my admiration for you is as boundless as the sea of stars......"

"Okay, don't be a sycophant, if you have time, let's hunt some swift beasts, the ecological balance of the grassland has been broken by those remnants of the defeated generals!"
