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

The eyes at the helmet were emitting two blue lights. Suddenly, the armor began to move and the body became tense into a straight line.

“Prepare to take off, 3, 2, 1.”

Zhang Yang issued a takeoff order in the armor. Jarvis connected Stark's computer and performed crazy calculations. The aircraft on the sole of his feet spewed out red and white flames, and the heavy armor floated up. Zhang Yang leaned forward slightly, and the armor changed direction and rushed out from the entrance of the underground parking lot.

"Oh!"

Zhang Yang shouted excitedly. This feeling of weightlessness was so exciting. He adjusted the flying angle and stability on both sides of his body, and tried to make a few rolls and excitement without any discomfort, and the overload was not as powerful as he imagined.

"The shock absorption system of this armor is so abnormal that it is outrageous!"

In front of Zhang Yang, the virtual image shows nearby terrain and buildings, as well as 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 bump into those planes.

The silver armor dragged its tail flames and flew over Los Angeles under the night. Jarvis kept conducting various tests. Many virtual images appeared in front of Zhang Yang's eyes. Suddenly, Jarvis's voice came.

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

In front of Zhang Yang's eyes, Stark's avatar was displayed.

"Zhangyang, how does it feel to be stable in operation?"

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

“It’s very smooth to operate and the flight is very stable.”

“How about cooling and flight power consumption.”

Red and white flames were sprayed on the soles of the feet and palms, but there was almost no heat. According to the flight power consumption, the current speed was 200 meters per second. The energy of the micro reactor was enough to supply armor to fly continuously for more than ten hours.

In front of a house, a little boy was looking out the window boredly. Suddenly, he saw a meteor passing by and began to make a wish excitedly. Zhang Yang's eyes widened the little boy's avatar, making him smile slightly, and deliberately approached a little.

The little boy opened his eyes and suddenly found that the meteor was getting closer and closer. From a distance, he looked like a man in iron! The little boy shouted immediately.

"Mom, there's Superman!"

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

"No, mom, there's really Superman!"

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

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

After recording the current data, Zhang Yang was preparing to fly vertically and test the limit of the flight altitude. The place where he flies is at the junction of the city and the seaside, with a relatively small population. Zhang Yang controlled the armor to draw an arc and flew up suddenly.

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

"What is the record of the Blackbird Fighter of the SR-71?"

"The flight altitude of the fixed wing is 26,000 meters above sea level, and we should not reach this height."

Zhang Yang felt the motivation coming from the armor and shouted.

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

Unlike in the plot, Zhang Yang was conducting the test flight, and Zhang Yang also replaced the material of the armor with gold-titanium alloy. When the original armor was at an altitude of 10,000 meters, the main sensor failed and the outside was frozen. Zhang Yang should exceed this speed this time.

“1500 meters, 3800 meters, 6300 meters….”

The flight altitude in front of Zhang Yang continued to rise, and the aircraft under his feet suddenly ejected even more dazzling flames. A layer of white mist instantly appeared around the armor. This was a sonic bomb cloud. The armor broke through the speed of sound at the moment just now.

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

Under Zhang Yang's feet were the lights, the whole city became very small, and on the other side was the deep darkness, which was the Western Pacific.

"Flying altitude is 12,600 meters, speed is Mach 1.87."

"continue!"

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

At such a height, the temperature is already very low and the oxygen is relatively thin. If Zhang Yang is in the daytime, you can see the ground turning into an arc, taking the shape of the earth, and you can also see the arc-shaped atmosphere.

A red warning suddenly appeared in front of Zhang Yang's eyes.

"Warning, the flight altitude is 18,000 meters, and the outside of the armor is frozen, which is likely to cause damage to the armor, which will endanger your life safety. Please lower the altitude immediately."

Zhang Yang felt an abnormal tremor around the armor, as if he was about to disintegrate. His heart suddenly tightened and immediately lowered the flight altitude. He dropped to a speed of 8,000 meters, and the tremor of the armor stopped. Zhang Yang did not dare to continue flying around and was preparing to go back for a check.

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

"Okay, come in from Yuan Luffy, don't smash my wall."

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

"Damn!"

Before Zhang Yang could react, he was dumped.

“Ping Ping Pong.”

A chaotic sound of Pilibala came, and the entire armor suddenly disintegrated in the air, while the Qi Yang, who maintained the inertial movement, had no protection in his whole body, and then he hit the wall of the underground passage heavily.

"Zhang Yang! Zhang Yang!"

Stark was about to celebrate Zhang Yang's safe return, but when he saw the sudden disintegration of the armor, Zhang Yang was thrown on the wall. He was shocked and pushed the table away and ran over.

"hiss."

Zhang Yang took a breath of cold air and climbed up from the ground. When the armor was disintegrated, Zhang Yang immediately used his mental power to plaster on the wall, reducing a lot of inertia, but even so, Zhang Yang's left arm still lost consciousness.

Zhang Yang saw his left arm thrust and pulled, and a biting pain came, and then he found that he could not move his left arm.

"It should be a dislocation, hopefully it's not a fracture."

Zhang Yang went to the hospital for an X-ray, but he was simply dislocated and had no fracture. After taking his arm, he returned to Stark's home. Stark collected the parts of the armor and was checking what went wrong.

"There is no problem with the armor itself, there is no damage, and the flight system is no problem. I think it may be a resonance problem, and I need to recalculate it."

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

"Because the components of the armor themselves are not exactly the same, the vibration frequencies of different metals are different during flight. It may be because different metals have problems due to resonance during high-speed flight, resulting in the separation of armor components and disintegration."

Zhang Yang doesn't know the details. Anyway, the armor disintegration will be lucky to happen on the ground. If it disintegrates at a high altitude, Zhang Yang will be completely finished.

"Can it be solved?"

Zhang Yang frowned. There seemed to be no such thing in the plot. Stark thought for a while.

"We need to redesign the proportion of metal alloys. The first point is to reduce the weight of the armor, and the second point is to keep the metal parts consistent and prevent disintegration again. These two points are mainly these. The rest need to be improved is the simplification of the flight system. Some redundant and unnecessary functions will occupy the CPU's memory, which may cause the flight system to collapse in serious cases."

Unlike Zhang Yang's expectation, many problems with the armor will jeopardize the user's life, which makes him helpless. He thought of his own mission - defeating Obadie Stan. According to time, Obadie should be about to build the armor now.

"Our hurry up, Stark, I have a bad feeling."

Zhang Yang could only make Stark speed up, and there was nothing else to do. When he was recuperating, Zhang Yang remembered the rewards the system gave him. Before he could check it, he opened it and found that it was a note.

"You have received the mission reward prop: PR—Assas—13 Invisible Technology Armor Drawings (Incomplete)."

Zhang Yang widened his eyes and said in a lost voice.

"Invisible Armor?"

"Props introduction: PR-Assas-13 Invisible Technology Armor Drawings (Incomplete): This is the advanced technology of other planets. The high-tech Invisible Technology Armor from Cybertron can be equipped on the body of the Autobot, but it has requirements for size, so it was abandoned by the large Autobot, and the drawings have been lost. This is a corner of the incompleteness."

"Props effect: This drawing is a broken part. If you obtain a complete drawing (1/2), you can get a complete method of making stealth armor. Invisible armor can be equipped on steel armor, which can achieve complete optical stealth and infrared stealth, greatly optimize the armor itself, and can block the radar's sensing of armor."
