Compared to the excitement of lift-off, the process of landing is even more exciting.

Originally, Zhang Wenkai thought that he was slowly descending to the ground, but

"Ahh Zhang Wenkai exclaimed, his body was descending at a speed of 15m/s, and the rapidly falling body made him feel that there was nothing to rely on, because the anti-gravity particles had stopped moving.

Originally, the thrusters were used for the return voyage, but the thrusters ran out of fuel, so they had to use the freefall method.

"It's a good thing that I didn't use thrusters, otherwise it would have been faster." Zhang Wenkai stabilized his mind.

On the way to the landing of the steel armor, it does not fall all the time, and the anti-gravity particles must be activated every few kilometers to achieve the effect of buffering, and this can only be used.

In this way, when Zhang Wenkai reached the ground, it was already more than half an hour later.

Accompanied by "Bang! With a bang, Zhang Wenkai landed firmly on the ground, and it was not Xiao Na who greeted him, but a burst of white gas.

After encountering this white gas, Zhang Wenkai could feel that the surface temperature of the steel armor was obviously decreasing.

The white gas is liquid nitrogen, mainly to prevent the oxidation of steel armor due to high temperatures

"That's it!" Although his feet were on the ground like stepping on cotton, Zhang Wenkai still shook his head calmly, this flight experience made him addicted, and he had fallen in love with this exciting feeling.

"Improve, must improve!" Zhang Wenkai's only idea now is to transform the steel armor into an existence that surpasses Iron Man, and he wants to create a Chinese version of the Iron God.

On the way to land, he already had a lot of thoughts in his head.

One of the most critical ideas is to solve the problem of decay caused by the use of anti-gravity particles at superfrequencies.

"Can Cortana replace the anti-gravity particles before they cause decay?" This is what Zhang Wenkai thought, just like there is no oxygen in the oxygen cylinder, it can also be perfused, and when the anti-gravity particles are about to fail, they are released and re-infused with new anti-gravity particles to achieve the effect of continuously rebounding gravitational waves.

Another advantage of this is that it can be used at an over-frequency at all times, because the anti-gravity particles can be replaced at any time.

Xiao Na was a little surprised, he didn't expect Zhang Wenkai's head to open up.

"Sir's idea is right." As she answered, Cortana had already sorted out this function and related design solutions.

On top of the original steel armor, Cortana has expanded space on her back and on both sides of her body to store spare anti-gravity particles.

At present, anti-gravity particles are displayed in the form of gaseous state (in fact, they are in the particle state), and noble gas is added to them, so there is no need to worry about the interference of the anti-gravity particles from the outside world.

"We still have to calculate the specific power." Because there are many involved, how much power can be supported by a unit volume of antigravity particles, and how long they can be used, all need to be calculated.

"The ultimate speed can reach 961 kilometers per hour, which is equivalent to the speed of a Boeing 747, but at this speed, he can only fly for ten seconds, that is, he can fly 2610 meters, and the temperature can be 600 degrees in an instant during this period."

"After that, Mr. must quickly replace the anti-gravity particles, otherwise the qualitative anti-gravity particles will cause great damage to the body, and the emitted electromagnetism has exceeded the limit that the body can resist, even if it is injected with anti-electromagnetic radiation vaccines."

Xiao Na had already calculated the values of the relevant aspects, and after Zhang Wenkai's words were spoken, she told Zhang Wenkai in detail.

"Hmm!" Zhang Wenkai nodded thoughtfully and continued: "It doesn't take that much speed. ”

Cortana controlled the holographic workspace and remained silent.

"By the way, can you add batteries to it?" Zhang Wenkai felt that if the launch station was only used, the restrictions of steel armor were too great, because the launch station was not yet popular, so there were many places where steel armor could not go.

"Can't do it!" Cortana shook her head, it's not that she can't do it, but the volume doesn't allow it, the volume of a battery is too large, and it can't be added to the original steel armor at all, and blind addition will only affect the overall function of the armor.

"Hey!" Zhang Wenkai sighed lightly.

So the two of them began to improve the steel armor

A week later.

"The suit is qualified!"

"There is no problem with all the parts of the body!"

"Alternate anti-gravity particles have been added."

"The multi-layer lamination has been installed!"

“”

Tonight is the second test flight, Zhang Wenkai is like a tenacious little strong, he has to develop armor that surpasses Iron Man, he doesn't hit the south wall and doesn't look back, but it doesn't seem to be the south wall.

The steel armor of this test flight is very different from the past, it is thicker, like a big fat man, but don't underestimate this steel armor, this is the most perfect design.

This time, instead of thrusters, anti-gravity particles were used.

At a speed of 100 km/h, it took only 15 minutes.

After arriving in the air, Zhang Wenkai began the experimental process.

"Go up at maximum speed!" As soon as Zhang Wenkai finished speaking, the heavy steel armor rushed out at a speed of 961 kilometers per hour.

Ten seconds later, I heard Zhang Wenkai shouting loudly: "Get rid of the outermost secondary armor quickly." Because Zhang Wenkai has already seen that the overall armor is a little red, and the temperature is also rising sharply.

As soon as he said this, it was like molting, and the armor ejected, and their bodies immediately lost a lot of weight.

Zhang Wenkai breathed a sigh of relief, this mode of discarding the secondary armor was discussed by him and Xiao Na later, the high temperature problem caused by the excessive use of anti-gravity particles cannot be solved by cooling means in the air, so it can only be discarded together with the high-temperature outer armor and scrapped anti-gravity particles, but don't worry, there are still several layers of such structures inside.

Zhang Wenkai repeatedly tested all kinds of difficult movements and ultra-high speed in the air, and only after he discarded all the sub-armor around his body because of the high temperature, he obediently returned home.

Now, the body of the steel armor is no different from the size it used to be.

This is the last layer of steel armor and cannot be discarded, only the anti-gravity particles can be replaced.

"Cortana, get ready for liquid nitrogen, I'm going to increase my landing speed." Zhang Wenkai is not willing to go to a speed of 100km/h. (To be continued.) )
