Under the clear sky and blue sky, the Hudson River rushes through the mountains, across the city, towards the Atlantic, the wide river has a thin layer of ice, slowly melting under the morning sun, but one section of the river is about three or four thousand meters long, but there is no ice or snow.

If you dive to the bottom of the river at a depth of 50 or 60 meters, you can see the artificial creations on the riverbed: reinforced concrete columns, and a metal pipe nearly a meter thick, and the heat emitted by these pipes is quite amazing, so that the temperature of the water around the pipe rises by more than ten degrees, and even the surface of the river rarely freezes.

Around and in the middle of this large ring pipe, there are countless large and small instruments, which together form a large ark reactor that is 100 times more complex than the nest of clothes, to supply energy to the Avengers 2 base next to the Hudson River.

Stark had built an Ark Reactor to power Stark Tower, making Stark Tower energy self-sufficient, but the Ark Reactor was only an experimental model for verification, and this was the official model, producing three times more energy than Twist.

The reason why Avengers Base II needs so much energy is because the underground of Avengers Base II has been hollowed out, and it has expanded to the surrounding area by tens of meters, it looks like there are only a few buildings on the ground, but there is a huge building complex underground, and it is estimated that only the Western Base of S.H.I.E.L.D. has long collapsed.

But unlike the S.H.I.E.L.D. western base, there are no people in the underground base here, all of which are all kinds of machinery and equipment, not to mention automated, and the maintenance is also done by robots controlled by Jarvis, which used to only appear in scenes in science fiction movies, but now it has been realized by Stark.

This is the exclusive production line of the steel suit that Stark spent several years to design, an absolutely intelligent production line, which was used to be made by Stark Industries' factories to manufacture related parts, but after Iron Man became known to the world, the number of Stark Industries' spies instantly surged dozens of times, and the largest one lurked around Pepper.

Because of this, Stark began to pay more attention to secrecy, and used to only ship the processed parts back to assemble them, but since then, Stark has set up a small processing factory under the villa on the West Coast, and transferred some confidential parts there for processing.

But Stark was not satisfied, and then built a more complete and huge factory on the top floor of Stark Building, which could process and manufacture most of the steel suit parts, but unfortunately the war of twisting was ruined. As a result, this base has become another Stark secret factory and warehouse, which stores a large number of semi-finished and finished parts of steel suits, and can also process most of the parts.

Stark had built and tested nearly twenty sets of steel suits here, and today this secret factory is once again in operation, with countless precision robotic arms moving flexibly, shaping all kinds of metal, converging them in the assembly workshop, and quickly combining them.

It's just that it is not combined into a steel suit, but a certain part of the parts, which are larger than the ordinary steel suit for more than three turns, and finally packed into boxes and transported to the semi-bunker test site by 'elevator'.

The steel arm on the test bench is not covered with a protective shell, which makes the anti-Hulktop armored robotic arm reveal more details: dense electronic components, all kinds of metal parts are precisely combined, and they are all drawn on the blueprint, which can fill a room.

Banner, with messy hair and oil-stained white coat, was looking down at the freshly baked metal arm, and from time to time he had a heated discussion with the equally unkempt Stark, and after the self-inspection and manual inspection were completed, the anti-Hulk armor attack experiment officially began.

"The fifty-eighth attack experiment, the countdown begins!" With Stark's command, the mechanical arms next to the test bench moved in unison, controlling the huge metal arm to spread its five fingers, so that the 'disc' in the palm of the palm was aimed at the empty test field.

"thirty,:twenty-nine..."In Jarvis's countdown, a large amount of energy was transmitted along the pipeline from the large ark reactor at the bottom of the Hudson River, pouring into the steel arm, causing the exposed electronic components of the steel arm to light up one after another, and finally converge into the palm of the hand, making the 'disc' glow dazzlingly.

“... two、one、zero。 As soon as Jarvis's countdown ended, a brilliant beam of light was launched from the palm of his hand, instantly bombarding the metal target a hundred meters away, and the point where the metal wall up to one meter thick was attacked instantly turned red, and molten iron flowed down.

The high-intensity attack lasted for half a minute before it stopped, and a large hole appeared in the special metal wall, and the metal around the emitter of the metal arm was burned red, and there were signs of deformation, and the air was slightly distorted by the steam.

Stark took off his goggles that filtered out the glare and trotted all the way from the console to the steel arm, frowning at the reddened half of his palm, Banner next to him shook his head and suggested, "You have to make the power a little smaller, otherwise..."

Later, needless to say, Stark naturally understands the consequences, half a minute of full power firing will make the arc pulse cannon break like this, that is to say, if the battle is fierce, it may not be able to support the end of a battle, and if it is replaced by a high-intensity battle like the Battle of the Twist, it may be just started, and the parts will have to be replaced, which is too deadly.

Stark didn't say anything, turned his head, looked at the holographic display on the opposite wall, and said, "Greel, are you ready there?" ”

"It's ready to start." From the other end came Greer's rather indistinct voice, mixed with the noise of full helicopter propellers, and the wind 'Whew!' Call! Stark turned and walked to the console, and said without looking up, "Get ready and start." ”

Jarvis is also very 'sensible' adjusted the picture to the test site next to it, a composite armor plate is placed in the open space, simulating a steel suit, sensors are all over the inside and outside, can monitor changes from moment to moment, and above this composite armor plate, an unmanned helicopter painted red and gold hovers at a height of 80 meters.

The cabin door was wide open, and Grell peered down and shouted into the headset, "Then I'll start." ”

It wasn't until Stark's affirmative voice came from the other end that Grell took off the headset, reached out and pulled out a knight card from the knight's card case, and inserted it into the drive around his waist:

“Kamen Ride decade！”

The moment the loud mechanical synthesis sounded, nine phantoms appeared around Greel, instantly merging with Greel, turning into Kamen Rider Decade, the purple crystal on his forehead lit up, and then jumped out of the helicopter.

Once again, he pulled out a card from the knight card box on his waist and inserted it into the Neo decade drive on his waist:

“Final AttackRide D-D-D-Decade！”

The ruby in the center of the drive lit up, and the light projected eight hologram-like card-shaped light walls in the void, and each time he passed through a card-shaped light wall, the golden energy light of his right foot was filled with a point, and when all eight cards disappeared, the golden energy light lingering on his right foot was already dazzling like a small sun.

A kick from the sky, 'Boom! There was a loud bang, the whole base trembled, the water surface of the Hudson River rippled, and the huge test site was covered by the dust that was raised, and it was gray like a rolling sandstorm, covering the sky and the sun, and there was no distinction between people and animals half a meter away.

Banner lifted his glasses in some surprise and said to himself, "His strength has increased again." "After more than half a year, Greer's destructive power has increased by a little bit compared to before, and his current strength may be able to suppress Hulk.

Thinking of this, Banner's mood suddenly improved a lot because the experiment was not going well, Hulk had been bothering him for ten years, and he was worried about Hulk's madness all the time, so he ran all over the country to find ways to control his emotions, including helping Stark make anti-Hulk armor, just to suppress Hulk.

The anti-Hulk mecha is still being tested, but Kamen Rider seems to be able to fight against the Hulk, and with Thor who has settled on Earth, Banner suddenly feels that Hulk is not a problem, and even if he goes crazy, someone can restrain him.

Stark didn't speak, his eyes fixed on the vast amount of data that the sensors had sent back before destruction, and the dusty proving ground.

The breeze came slowly, the dust dissipated, the large crater of the test site was gradually revealed, the ground was broken into a net inch by inch, as if the land had dried up to the extreme, the pit in the center was so large that there was still a surplus for ten large trucks to drive in, and as for the composite armor used for the experiment, not even fragments could be found, and it was completely vaporized.

"The destructive power is very strong, and the thirty tons you said are estimated to be a fraction." Stark's voice came from the headset, and Grell bent his knees and jumped out of the pit, moving his right leg that was shaken by the reaction force as he walked, and said, "I have concentrated the strength of eight knights, of course it is very strong. ”

When Grell walked into the lounge of the main building of the base, he saw Stark and Banner still wearing the dirty clothes, facing a plate full of food and large bones, Grell lifted his transformation, threw himself into the soft sofa, and said weakly: "How long will it take to experiment?" Schools are all open, alas. ”

"You've been absent from school for more than half a year, not worse than two or three months." Stark stuffed the cheeseburger into his mouth, and tapped his free hand on the watch screen a few times, and several holographic projection screens suddenly unfolded in the room, showing the results of today's experiment.

"The new material still needs to continue to be tested and adjusted, the energy conductivity is five percentage points higher, but the strength and ductility are reduced, and..." Stark chattered about the experimental data of the new materials he had researched based on the fragments of the Dark Elf spaceship and the data that Grell brought back from the universe, combined with the earth's metals, and in general, it was still in the experimental stage, and there was still a way to go before it was practical.

Greer has seen how many repeated experiments have to go through behind each mature product, and it has been three months since the end of the convergence of the Nine Realms, and in these three months, Greer has spent 99% of his time at Avengers Base II.

Stark and Banner worked around the clock experimenting with new materials, and every time they came up with a new metal material, they would use it to make parts of a certain part of the steel suit, conduct a lot of experiments, and when they were done, they asked Grell to kick the knight to get more data.

"When will these days end?" Grell lamented in his heart, he thought that with all the information about the nano armor provided by Stark in the future, Stark would be able to quickly make the nano armor, so that the strength could be instantly raised to the level of "Avengers III", but he was poured cold water.

Stark didn't ask for the source, but just showed Grell that Howard implied a video of the Ark Reactor, which made Grell understand that there are many things that you can't design and build.

For example, if you want to build a mini four-wheel drive car in ancient times, you must first invent plastics, make magnetic engines, batteries... Don't look at the simple structure, but there are a lot of things involved.

The core of nano armor is nanorobots, and it is necessary to invent equipment for manufacturing nanorobots, as well as metal materials suitable for nanorobots, micron-level lithography machines, and new ark reactors... These things, even if there is information, must be produced little by little. (If only the data could have done everything, Spey Engines would not have been delayed for twenty years.) ）

Stark and Banner were discussing the details of the experiment with great interest, so much information about technology far beyond human beings, giving them endless motivation, eager to spend 24 hours a day on research, trying to get through these materials as soon as possible, and turn these technologies into their own use.

With this information, the standard of anti-Hulkhead armor has been raised by nearly half compared to the beginning of the design to ensure that it can suppress Hulk 100%, therefore, a large number of new technologies are used, such as new materials, new energy transmission methods, new...

In the room, the discussion between the two was hot, one pretended to be lying on his stomach, and suddenly, Jarvis's voice sounded: "Sir, there is your request for emergency communication." ”

"Who?" Stark continued to stuff the cheeseburger into his mouth.

"Unknown number, the signal is located at 51°10′ north latitude and 1°49′ west longitude."

"Where is this?"

"Stonehenge!"

"Stonehenge?!" Hearing this, Grell jumped to his feet and shouted, "Jarvis, get on now." ”

"Is there anything there?" Stark was a little surprised by Greer's overreaction, as if he had heard something terrible.

"The spatial passage, it appeared before the convergence of the Nine Realms, isn't it over? Wait a minute, is it possible to form a stable spatial communication..."As Grell was speaking, Stark asked Jarvis to answer the phone, and a hurried voice came out: "Stark, do you hear that?" I need your help. ”

Along with this sound, there is also a simultaneous 'Da! Da! The crisp gunfire and the sound of explosions were fierce like a battlefield, and the person who spoke seemed to be Coulson.
