After a few days of fabrication and debugging, the steel armor was finally completed, which should have been done a long time ago, but it took a lot of time to make the thrusters and artificial muscle suits.

Thrusters are used primarily to increase the armor's flight speed, and have no other purpose.

After all, the current steel armor using anti-gravity particles can only provide 30km/h, and on the ground, it can be said that it is relatively fast, but in the air, this speed is not even as fast as a turtle.

At this time, it was already more than ten o'clock in the evening, and Zhang Wenkai chose this time to conduct a test flight, just to avoid some unnecessary trouble.

He put on a suit with artificial muscles, this suit is semi-transparent, but it can change color, so Zhang Wenkai can't help but be careful about what to go through, and besides, Xiao Na is alone, what's the big deal if she goes naked, I'm afraid Xiao Na knows Zhang Wenkai's body in more detail than himself.

This suit is one-piece, except for the head, it is basically wrapped.

And this suit is very different from the previous suit, that is, it has a lot of thickness, and the reason why it is so thick is that it increases the strength of the suit itself, after all, to drive the entire steel armor, the strength is not good.

After moving their bodies a few times and feeling very comfortable, Zhang Wenkai and Xiao Na walked towards the top floor of the building, where the steel armor was on the top floor.

"If you have symptoms such as lack of power, abnormal system, or feeling that your body is getting heavier or your head is dizzy, I hope my husband can return to the ship in time." Cortana made a final reminder.

Theoretically, as long as the electricity is interrupted, the anti-gravity particles can constantly bounce off gravity and make objects fly, but some unexpected situations are not ruled out.

What if the power goes out at the transmitting station, what if there is a problem with the wiring inside the armor? These are all issues that need to be paid attention to and prevented.

Zhang Wenkai nodded solemnly, he would not joke with his life.

When I came to the roof, there was a gentle breeze, and it was the hot and humid time in this season, and after this wind blew, I obviously felt a lot cooler.

The breathability of the suit where you can feel the artificial muscles is good.

"Sir, you put on the steel armor first, and then give you the thrusters." Xiao Na has been frowning since she beat Zhang Wenkai upstairs, and the main reason is that she is worried about Zhang Wenkai, after all, she is flying high in the air.

Zhang Wenkai looked a little relaxed, the steel armor is equipped with a smart brain, through the smart brain, Xiao Na can carry out complete control, and the artificial muscle suit is also connected to the smart brain, through which the suit can be controlled.

The steel armor made this time is much smaller than the previous one, with five points similar to Iron Man, and the remaining five points are redesigned by Zhang Wenkai and Xiao Na, after all, it must conform to the mechanics of flight.

The only thing that is special is the face of the steel armor, the smooth metallic texture, it seems that this face is extremely cold, looking at the part of the eyes, but it looks more hideous, three pairs of compound eyes are added to the forehead, plus the original eyes, the whole eight eyes are arranged in a symmetrical way, some like spider eyes.

Originally, there was no need for so much, but virtual reality technology was used on the head of the steel armor, which was also convenient for Xiao Na to guide Zhang Wenkai.

Zhang Wenkai took a sip of incense on Xiao Na's forehead, and then stood next to him and asked Xiao Na Liudao to put on steel armor for him.

The order of dress is also very particular, you must first wear the front of the chest, then the back, then the limbs, and finally the head.

On the chest of the artificial muscle suit, there is a circular connector, which is used to connect the Di Rong coil, and the internal circuit does not use wireless technology, but also to ensure that the transmission of current is not interfered with.

A few minutes later, Xiao Na Liudao put on the armor for Zhang Wenkai, pulled out a thin thread on the collar of the suit, first connected it to the helmet, and then put on the helmet for Zhang Wenkai.

As soon as the helmet was put on, Zhang Wenkai's vision fell into darkness, and it took a few minutes before it lit up.

Glanced around a few times, the line of sight was very emotional, different from the past, after using virtual reality technology, in his sight, each object's body was glowing with a faint halo, obviously the image obtained by the night vision function was processed by the brain, restored to the appearance in front of him.

Around his line of sight, there were many words and graphics floating.

A diagram of the structure of the steel armor, just to his left, can see the current pressure inside the steel armor, as well as the operation of some equipment.

And when she looks at Cortana Liudao, she will also mark the number A1A2.

Zhang Wenkai stretched out his arm to perform a virtual operation.

"Open the airbag damping system."

"Detect the spoiler."

The next time, Zhang Wenkai began to check whether the entire set of armor was working properly according to Xiao Na's instructions

"Everything works!" Zhang Wenkai nodded.

After Zhang Wenkai's confirmation, Xiao Na Liudao took out two cylindrical objects, which were thrusters placed on his legs, and he was able to make Zhang Wenkai quickly enter the stratosphere.

"Buzz!" With the rotation of the screws, the two thrusters are mounted on the legs, which does not affect the movement in the slightest.

"Start!" Zhang Wenkai's body stood straight, and at the same time, his body had slowly begun to rise.

At this moment, his heart is excited, he can fly in the sky, and he is absolutely so good that he has no friends.

"Sir, I'm going to turn on the thrusters." Cortana's voice rang out.

"Hmm!" As soon as Zhang Wenkai said the word, the thruster on his leg burst into flames, and with a huge force, Zhang Wenkai soared into the sky.

His vision is not dark, and through night vision, he can clearly see the sky, even the clouds.

And during the flight, there was no pressure on his body at all, because the gravitational force had been bounced back by the anti-gravity particles and could not affect his body.

After he passed through a thick layer of clouds, there was no cloud in front of him, Zhang Wenkai knew that he had entered the stratosphere, and through the data, he could know that he was now at an altitude of 20,000 meters.

He wasn't surprised at the heights he was, he was surprised that it only took a little more than a minute.

"I'm afraid it's all up to the speed of sound!"

Just as he was about to fly up, the thrusters ran out of fuel and could no longer fly, so he had no choice but to start wandering around the stratosphere at a speed of thirty miles.

From the data given in the line of sight, it is known that the temperature outside is -56%.

"If this is exposed to the air, it will probably freeze in a few seconds."

"And it's not just freezing, it's suffocating in a minute." Zhang Wenkai sighed continuously. (To be continued.) )
