When the Mark 2 was flying test, it was sternly stopped by Chen Mo when it flew to an altitude of 150,000 feet.

Although the Mark 2 did not have icing problems at that altitude that exceeded the flight limits of the aircraft, it does not mean that Obadiah's Iron Overlord will be safe and sound.

You must know that Mark No. 2 has been improved and strengthened many times under Chen Mo's guidance, and the gap between Mark No. 2 and Mark No. 1 is simply immeasurable.

And Obadiah is based on Mark 1, and the Iron Overlord hastily created in such a short period of time, except for its huge size, strength and defense advantages, it is impossible to compare with Mark 2 in other aspects, especially in some places that Tony himself has not discovered, such as the problem of high-altitude icing.

As soon as he thought of it, Tony relied on his speed advantage to deliberately maintain a distance from Obadiah and lead him high into the air.

Although the Iron Tyrene's thrusters are huge and the flames spewed out are far thicker and more spectacular than Tony's Mark II, due to the huge gap in technology, the propulsion power is actually far less than that of the Mark II's smaller energy engine.

Coupled with the heavy weight of the Iron Overlord, its flight speed was actually not fast, so Tony suppressed the speed and always maintained an almost accessible distance, so that Obadiah, who was red-eyed and wanted to kill Tony, followed him into the air without hesitation.

Although they suppressed their speed, the two quickly entered the air at tens of thousands of feet.

Seeing that he was about to catch up with Tony, Obadiah taunted excitedly.

"Tony, your design is great, but alas, my suit is more advanced!"

Indeed, judging from the performance of the two since they fought, Tony's Mark II has been comprehensively suppressed, and the strength of Mark II itself is not as strong as the huge Iron Overlord, and he is equipped with very few weapons, and there are no heavy weapons, so he is not a threat to the heavily armored Iron Overlord at all.

It's just that Obadiah, who was chasing after Tony, didn't notice that the surface of the Iron Overlord's armor had begun to freeze, and as they flew higher and higher, the ice on the surface was also rapidly thickening.

"So how did you solve the icing problem?"

Tony replied with a glance back at the thick ice on the Iron Overlord.

"Icing problems?"

Obadiah didn't quite understand, after all, he was just a businessman, and he was not tech-savvy.

Their altitude at this time had not yet reached the 85000-foot flight altitude reached by the SR-71 Blackbird high-altitude high-speed strategic reconnaissance aircraft, but it had already exceeded the flight limit of ordinary aircraft.

As soon as Obadia's words fell, the Iron Overlord's thrusters stopped working after a series of muffled sounds, and the suit's operating system also crashed in this extremely low temperature condition, and the entire suit completely lost power and fell downward.

Tony breathed a sigh of relief and stopped, originally thinking that this suit was already perfect, but he didn't expect that a lot of problems were exposed in the actual battle, and thanks to Chen Mo's improvement of Mark II, otherwise he would not be able to defeat Obadiah this time, it seems that the steel suit still needs to be upgraded.

Looking at the Iron Overlord who was speeding down below with some complicated feelings, it wasn't until he was almost out of sight that Tony controlled Mark II to fly towards the ground and returned to the place where the two had just fought, in the Stark Industrial Park.

He was physically and mentally exhausted from the fierce battle just now, and what he wanted to do most at this time was to take off his armor and rest.

Just as he opened his helmet and was about to catch his breath, the Iron Overlord, who should have crashed, suddenly fell behind him, and before he could react, he used his thick and powerful right mechanical arm to firmly strangle Mark II.

The previous high altitude and low temperature did cause a thick layer of ice to condense on the surface of the Iron Overlord, and the internal control system also crashed at low temperatures, but Tony ignored the Iron Overlord's huge size and the thickness of his armor.

While it did freeze at first, falling to the ground, it wasn't that bad.

The temperature inside the suit just exceeded the lower limit of the control system, but in the process of falling, the temperature of the environment continued to rise, and the violent friction between the suit and the air at high speed also generated a lot of heat, and the ice on the surface fell off under the impact of tumbling and air currents, and the temperature inside also rose rapidly.

Before falling to the ground, the control system finally restarted and the thrusters resumed working, allowing the Iron Overlord to land safely to the ground.

Immediately, Obadiah, who nearly fell to his death, went into hiding and waited for Tony Stark to land.

Just as Tony thought he had fallen and let his guard down, Obadiah suddenly flew out of hiding and landed behind Tony.

Before he could react, he grabbed him with the advantage of strength and pinned him to his chest, while raising his left hand, which was equipped with a giant impact hammer, and slammed it into Mark II's head.

The moment Tony found that he was strangled, he quickly closed the mask of the battle suit, and struggled hard at the same time, but unfortunately, compared with the Iron Overlord, who was several times larger than him, his strength was still a little insufficient, and seeing that he couldn't get rid of the struggle, Tony had to grit his teeth and resist.

The heavy impact hammer hit Mark 2 on the head hard, and the huge impact force shook the entire suit, and Obadiah in the Iron Overlord could feel the huge vibration coming from the suit, and the parts that directly received the attack were slightly deformed.

A fierce smile appeared on Obadia's face, and today, he was going to completely solve Tony Stark, the biggest obstacle to his complete mastery of Stark's industry.

Fortunately, the defense of Mark II is extremely strong, and Tony Stark inside the suit only felt that his entire head was shaken a lot, and he was a little dizzy, but he did not suffer substantial damage.

In the movie, Tony Stark, who was wearing Mark III, was hit by a tank shell and fell directly from a high altitude, smashing a large hole in the ground, but only the surface of the suit was slightly damaged, and the body under the protection of the suit was unscathed, which shows the strong defensive performance of the steel suit.

In addition to the strong defensive performance of the gold-titanium alloy armor, the biggest role in the defense system of the entire suit is actually a special shock-absorbing cushioning system.

This technology can be said to be the core technology of the steel suit, and it is with it that the steel suit can have super defense power that surpasses that of heavy tanks in such a small size.

This shock-absorbing cushioning system, which can be regarded as a black technology, is also what Chen Mo values the most, if it weren't for Tony Stark, relying on the power of Hydra alone, it might not be possible to study it for hundreds of years.

Only Chen Mo, who personally participated in the design and manufacturing process of the Mark II, knew what was the most valuable thing in this suit.

The design of the Ark reactor energy, the flight thrusters, and the entire suit's drive system, while highly technological, is not absolutely impossible to manufacture.

In Iron Man II, Hammer Industries copied armor similar to the Iron Suit, although it was still immature at the time, and in many ways it had a big gap with Tony Stark's Iron Suit, and it was completely completed with the help of another genius scientist, Ivan Vanko, and had actual combat ability.

But even so, they are just some remote-controlled steel machines, with average speed, defense, agility, handling, etc.

Moreover, without the core shock absorption and cushioning system developed by Tony Stark, if a person is driven inside, a strong attack or a huge impact force generated by a fall will directly shock the operator to death.

The whip mecha made by Ivan Vanke seems to be powerful, but in fact, it only relies on two flexible and powerful energy whips, which make people unable to get close, and its own defense ability is not strong, mainly relying on the surface of the steel armor for protection.

However, the shock absorption and cushioning system invented by Tony Stark can greatly weaken the impact force of the outer defensive armor, and the final impact transmitted to the body is minimal, so it can be said that as long as the outer alloy armor is not broken, then the life of the person inside will not be in danger.

Therefore, Obadiah's attack did not directly shock Tony Stark to death as he wished, but the gold-titanium alloy used in the outer defensive armor of Mark II, although it is a super strong special alloy used by the Seraphic military satellite, is not indestructible after all, and it is still slightly deformed under the attack of the heavy impact hammer.

Obadiah was not annoyed when he saw that he couldn't take out Tony with a single blow.

"What a surprise! Looks like you've upgraded your defenses as well! ”

Obadiah couldn't help but marvel at the strong defense of the Mark II.

"Tony, you're a genius!"

"Unfortunately, you have to die today!"

Obadiah's face began to turn hideous as he spoke, allowing Tony to struggle uselessly under the Iron Overlord's thick mechanical arm, and once again raised the hammer of his left arm to launch a series of attacks on Mark II's head.

Despite the offset by defensive armor and shock-absorbing cushioning systems, Tony's brain was buzzing with the constant onslaught, and he could only instinctively struggle uselessly.

"15% damage to the armor of the head!"

Jarvis's voice rang in Tony's ears, and a schematic diagram of Mark II's all-god armor appeared in his shaking vision, with a red alarm on his head and a progress bar next to it showing the degree of damage.

As the Iron Overlord's heavy hammer continued to bombard Mark II's head, the armor damage became more and more severe.

"Sir, the damage of the head armor is increasing rapidly, it has reached 37%, and the estimated damage time is 24 seconds!"

Jarvis's warning made Tony Stark anxious, but at this point he was powerless to resist.

Just as he racked his brains to think of a way to crack it, the damage of his head armor had reached 90%, and he saw that he would be completely destroyed after a few more attacks, and his head would be blown up along with it.

Still at a loss for what to do, Tony could only watch as the breakage continued to rise, and a sense of despair quickly rose in his heart, and he had already felt this powerless despair twice.

Once in the desert of Afghanistan, lost in the vast sea of hot sand, once was subdued by Obadiah with a nerve paralysis device and took the second-generation Ark reactor in his chest, and both times, Chen Mo appeared in time to rescue him from the brink of death.

It's just this time, not to mention that Chen Mo should still be in the seaside villa at this time, and he can't catch up at all, even if he really comes, it is estimated that he is not the opponent of Obadia's Iron Overlord, it seems that this time he is really going to die, but Xiao Pepper .......

Just when Tony let go of his last hope and was ready to face death with some regret and unwillingness, an incomparably brilliant silver sword light suddenly crossed his head.
