The silver steel armor exuded a dangerous aura and stood there silently.

The eyes at the helmet emitted two blue rays, and suddenly, the armor began to move, and the body stretched into a straight line.

"Ready for takeoff, 3, 2, 1."

Zhang Yang gave the take-off command in the armor, Jarvis connected to Stark's computer, and carried out crazy calculations, the aircraft on the sole of his feet spewed red and white flames, the heavy armor was suspended, Zhang Yang's body leaned forward slightly, and the armor changed direction, from the entrance of the underground parking lot, and rushed out.

"Oh!"

Zhang Yang shouted excitedly, this feeling of weightlessness was simply too exciting, he put his hands on his sides, adjusted the angle and stability of the flight, and tried to do a few tumbling excitement, without any discomfort, and the overload force was not as strong as imagined.

"The shock absorption system of this suit of armor is simply perverted to the point of outrageousness!"

In front of Zhang Yang, the virtual image shows the nearby terrain and buildings, as well as the situation of various aircraft, and marks the altitude and speed, Zhang Yang's current flight altitude is not high, and he avoids the vicinity of the airport, and will not hit those planes.

The silver armor dragged the tail flame, flying over Los Angeles in the night, Jarvis continued to conduct various tests, many virtual images appeared in front of Zhang Yang's eyes, and suddenly, Jarvis's voice was heard.

"Mr. Zhang Yang, Mr. Starck wants to talk to you."

In front of Zhang Yang's eyes, Starck's avatar was revealed.

"Zhang Yang, how does it feel to operate steadily."

Zhang Yang tried to maneuver in the air and change direction, and said with satisfaction.

"The handling is very smooth and the flight is very stable."

"What about heat dissipation and flight power consumption."

On the soles of the feet and palms of the hands, reddish-white flames are sprayed, but the presence of heat is almost not felt, and according to the flight power consumption, the current speed is 200 meters per second, and the energy of the miniature reactor is enough to supply the battle armor to fly continuously for more than ten hours.

In front of a house, a little boy was looking out the window boredly, and suddenly saw a meteor passing by, and immediately began to make a wish excitedly, and the little boy's head was magnified in front of his eyes, making him smile slightly, and deliberately got closer.

When the little boy opened his eyes, he suddenly found that the meteor was getting closer and closer, and from a distance, it seemed to be a man in an iron sheet! The little boy suddenly shouted.

"Mom, there's Superman!"

"Tom, you're lying again, don't make excuses for me, you need to go to bed on time."

"No, Mom, there really is Superman!"

In front of Zhang Yang, there are many virtual images, which indicate the flight altitude, flight speed, flight resistance, air pressure, wind direction, air humidity, energy consumption, driver's physical health monitoring, pupil lock object information, and a series of contents, all of which are calculated by Jarvis in the background.

"Jarvis, record, we're going to challenge the flight altitude."

After recording the current data, Zhang Yang prepared to fly vertically, testing what is the limit of the flight altitude, the place where he flew was the junction of the city and the seaside, the population was relatively small, Zhang Yang manipulated the battle armor to draw an arc, and suddenly flew away.

In front of Zhang Yang's gaze, there was a silver-white moon, Zhang Yang looked at it, and asked Jarvis.

"What is the record of the SR-71's Blackbird fighter?"

"The fixed-wing flight altitude is 26,000 kilometers above sea level, and we should not be able to reach this altitude."

Zhang Yang felt the momentum coming from the battle armor and shouted.

"Then let's try it and see if we can beat this record!"

is different from the plot, it was Zhang Yang who carried out the test flight, and Zhang Yang also changed the material of the battle armor to gold and titanium alloy, when the original battle armor was at an altitude of 10,000 meters, the main sensor failed, and the outside froze, and Zhang Yang should exceed this speed this time.

"1500 meters, 3800 meters, 6300 meters......."

The flight altitude in front of Zhang Yang's eyes continued to rise, and the aircraft under his feet suddenly spewed out more dazzling flames, and a layer of white mist instantly appeared around the battle armor, which was a sonic boom cloud, and the battle armor broke through the speed of sound in the moment just now.

"With a flight altitude of 8,000 meters and a speed of Mach 1.35, supersonic flight consumes more energy than ordinary flight."

At the foot of the flamboyant feet, the city is very small, and on the other side is the deep darkness, which is the western Pacific Ocean.

"Flying at an altitude of 12,600 meters and a speed of Mach 1.87."

"Go on!"

The final flight altitude was fixed at 17,579 meters, and the maximum flight speed had exceeded Mach 2.25, which theoretically reached the critical value of the battle armor.

At such an altitude, the temperature is already very low, and the oxygen is relatively thin, and if it is in the daytime, you can see that the ground has become an arc, taking on the shape of the earth, and you can also see the arc-shaped atmosphere.

In front of Zhang Yang's eyes, a red warning suddenly appeared.

"Warning, flying at an altitude of 18,000 meters, there is ice on the outside of the battleframe, which is very likely to cause damage to the warframe, and your life is in danger, please reduce the altitude immediately."

Zhang Yang felt an abnormal tremor around the battle armor, as if he was about to disintegrate, his heart tightened suddenly, and he immediately lowered his flight altitude. It wasn't until it dropped to a speed of 8,000 meters that the trembling sensation of the battle armor stopped, and Zhang Yang didn't dare to continue flying around, preparing to go back for an inspection.

"Stark, when the armor is at an altitude of 18,000 meters, the fuselage has a variable frequency of fluttering, which is likely to cause disintegration on the spot, we need to check it."

"Haode, fly in from the same road, don't smash my wall."

Zhang Yang lowered his altitude, flew towards Stark's house, flew in through the underground passage, and then adjusted the direction with both hands, and began to reduce the power of the aircraft, preparing to land, suddenly, the battle armor trembled violently, and suddenly disintegrated in the passage.

"it!"

Before Zhang Yang could react, the whole person had already been thrown out.

"Ping Pong."

There was a chaotic sound of thunderbolts, and the entire armor suddenly disintegrated in the air, maintaining the inertial motion of the open, without any protection from the whole body, and then slammed into the wall of the underground passage.

"Publicity! Publicity! ”

Stark was just about to celebrate Zhang Yang's safe return, when he saw the sudden disintegration of the armor, Zhang Yang was thrown against the wall, and he was suddenly startled, pushed the table away and ran over.

"Sss

Zhang Yang took a breath of cool air and got up from the ground, when the previous battle armor disintegrated, Zhang Yang immediately cushioned the wall with his mental power, reducing a lot of inertia, but Rao was so, Zhang Yang's left arm was still unconscious.

Zhang Yang saw his left arm shrugging and a piercing pain, and then found that he couldn't move his left arm.

"It's supposed to be a dislocation, hopefully not a fracture."

Zhang Yang went to the hospital to take an X-ray and looked at it, it was just a simple dislocation, and there was no fracture, and after connecting his arm, he returned to Stark's house, Stark collected the parts of the armor and was checking what was wrong.

"There's nothing wrong with the armor itself, there's no damage, there's no problem with the flight system, I think, maybe it's a resonance problem, I need to recalculate it."

Resonance? Seeing that Zhang Yang didn't understand, Stark said his guess.

"Because the parts and materials of the armor itself are not exactly the same, when flying, the vibration frequency of different metals is different, it may be because in high-speed flight, different metals have problems due to resonance, resulting in the separation and disintegration of the parts of the armor."

Zhang Yang doesn't know the detailed reasons, anyway, this time the battle armor disintegrated, luck happened on the ground, if it disintegrated at high altitude, then Zhang Yang would be completely finished.

"Can it be solved?"

Zhang Yang frowned, there didn't seem to be such a thing in the plot, Stark thought about it.

"We need to redesign the proportions of the metal alloys, the first is to reduce the weight of the armor, and the second is to keep the metal parts the same material to prevent the recurrence of disintegration. The rest that needs to be improved is the streamlining of the flight system, and some redundant and redundant functions will occupy the memory of the CPU, which may cause the flight system to crash. ”

Contrary to Zhang Yang's expectations, there were many problems with the Warframe, which would endanger the user's life, which made him very helpless, and he thought of his mission - to defeat Obadi Stan, according to the time calculation, Obadi should now be close to completing the Warframe.

"Hurry up, Stark, I have a hunch of displeasure."

Zhang Yang could only let Stark speed up, there was nothing else to do, when he was recuperating from his injury, Zhang Yang remembered the reward given to him by the system, and he didn't seem to have time to check it, he opened it and found that it was a note.

"You have received the quest reward item: PR-Ashas-13 stealth jishu armor blueprint (mutilated)."

Zhang Yang's eyes widened and he lost his voice.

"Stealth armor?"

"Props introduction: PR-Assas-13 stealth jishu armor blueprint (incomplete): This is the advanced technology of other planets, the high-tech stealth jishu armor from Cybertron planet, which can be equipped on the Autobots, but there are requirements for volume, so it was abandoned by the large Autobots, and the drawings have been lost, which is a broken corner."

"Prop effect: This drawing is a broken part, get the complete drawing (1/2), you can get a complete stealth armor production method, stealth armor can be equipped on the body of the steel armor, which can achieve complete optical stealth and infrared invisibility, greatly optimize the armor itself, and can shield the radar on the induction of the armor."

Stealth jishu armor! Zhang Yang's heart began to get excited.
