The majestic Rocky Mountains stretch and rise, nearly 5,000 kilometers from north to south, almost run through the North American continent, composed of countless countless large and small, high and low peaks, can be described as lofty mountains, heavy mountains and mountains, although the scale is large, but does not match the name of steep, the highest peak is only 4399 meters.

In the territory of Colorado, most of the slopes are low, and there are few mountains and majestic, steep edges. The main reason is that Colorado itself is at a high altitude, almost a plateau, and the peaks here are very low.

In addition, it is located inland, the climate is arid and the precipitation is very low, so the plants here are mostly low bushes, thorns, tumbleweeds and even drought-tolerant plants such as cacti, and the mountains are mostly exposed, which can be described as barren at a glance.

Most of the areas are barren and uninhabited areas or hundreds of kilometers along the highway to see a house, so except for a few people who like to challenge the limit, they basically do not attract tourists or travelers to explore and enjoy the beautiful scenery.

Such a no-man's land is an excellent base for S.H.I.E.L.D., with cold storage for criminals and dangerous goods built in a mountain far away from people, safe, hidden, and difficult to detect.

Yes, it's a building built in the mountains, not a building that stands high above the ground, and think about it, S.H.I.E.L.D. has always been a hidden form, and agents go out with several documents, for fear that people will guess that he is from S.H.I.E.L.D.

How can you build a building hundreds of meters high in a deserted place, and the entrance and exit are still on the roof, isn't this a clear way to tell people that there is a problem with this building?

And digging a shaft down from the top of the hill, building it layer by layer, is also a building in a sense, just like the lower town in Puerto Rico, the only entrance is at the top of the hill, and only a small number of guards are needed, so that the prisoners inside cannot escape and the outsiders cannot enter.

Even if the prisoners try their best to rush out of the entrance and exit, there is no way down the mountain, here all rely on planes to transport materials and personnel, such strict precautions, it can be called the strongest prison on the earth, it is not an exaggeration, the cold storage has been built for so many years, no prisoner can escape from here.

In the Kun-style transport plane that was speeding in the sky, Stark used a holographic image to show the structure of the prison, and successfully shocked Greel, S.H.I.E.L.D. is really generous enough, on a mountain three thousand meters above sea level, a shaft hundreds of meters deep was drilled, and a warehouse of one or two hundred floors was built as a part-time prison.

This is much higher than the cost of building a high-rise building on the ground, it can only be said that the rich are capricious, and even the prisons are built so differently, I really don't know how many prisoners they have to be imprisoned, and the money and food consumed every day are a sky-high number.

But...

"What are we doing here?" Greer asked suspiciously, now that S.H.I.E.L.D. and Hydra are almost in full swing, the human brain is about to hit the dog's brain, and both sides have suffered heavy losses, which can be regarded as the limit of one for one, and it is very necessary to fight the battle, but Stark drove the Quint transport plane to Colorado.

"Nick Fury has a lot of stuff in there, and it must not fall into the hands of Hydra." Stark said as he handed over the pilots to Jarvis, letting him control the Quint transport plane to slow down and lower altitude, with a series of mountain peaks below, some covered in green vegetation and more in bare weathered gravel.

"It's been so long, and if they want to transfer something, it's estimated that it has already been done." Grell was pessimistic, and after Alexander Pierce took control of S.H.I.E.L.D., he made drastic changes to S.H.I.E.L.D. in the name of investigation.

The Trident headquarters is about to become the lair of Hydra, and most of the previous leaders of the Hub Operations Department have changed, if there are really so many 'dangerous items' in this place, Hydra is estimated to have moved out.

Stark smiled mysteriously and said, "They didn't find it." ”

"Didn't find it?" Grell turned his gaze back to the structure of the cold storage, since they said they didn't find it, they must have looked for it, although the cold storage building area is very vast, but it takes a little more time, you can always find it, how can you not find it?

Stark, who sold the guan, said: "Because that layer was deleted in the design drawing, and it is not related to the control center of the cold storage, I don't know, even if the cold storage is blown up, don't think about finding it." ”

"In your hard drive, you even said this?"

"Nope." Stark shook his head, and with a wave of his right hand in front of the hologram, pulled the design to the bottom right corner, zoomed in there, revealing the designer's signature: Howard Stark.

Now it makes sense, the basement of the Stark family's warehouse is full of S.H.I.E.L.D. information, I don't know how many S.H.I.E.L.D. secrets are hidden, come to think of it, before Howard left office, there were no secrets in front of Stark, and this attack on the Trident headquarters, he must have obtained a lot of confidential information.

At this time, the Kun transport plane had arrived near the top of the mountain, slowed down to approach the top of the mountain, turned off the optical invisibility, and generously showed the detection radar to the cold storage, and then Jarvis sent back a password response signal, completing the identification of friend or foe, and was identified by the cold storage system as a S.H.I.E.L.D. transportation and supply aircraft.

Then, the Kun transport plane slowly landed towards the gentle ground below, and the earth covered with low grass and trees suddenly slid up, revealing a parking platform, allowing the Kun transport plane to be firmly parked on it.

"Jarvis, say hi to them." As soon as Stark's voice fell, a virus outbreak disguised as a password response signal sent by Jarvis instantly paralyzed the cold storage system, the lights went out, the elevator was shut down, and the automatic door was locked...

The entire base came to a standstill for a moment, and no one could get out of the room or go to the next room, as Jarvis had obtained the highest clearance, and all but the necessary ventilation systems were locked and shut down.

Grell witnessed the whole process and deeply realized what it meant to be 'technological power', and that such a large and well-defended base could be so easily stripped of its clothes and acted arbitrarily.

Jarvis is much tougher than before, it took a long time to break through the firewall to steal information in the Helicarrier, and it was discovered immediately, but now it is not an infiltration, but a system that directly controls the secret base of S.H.I.E.L.D., is simply a judgment between the two.

"Let's go." Stark got up from the flight seat, opened the Gana Library, began to dress in Mark 46, and strode off the Kun transport plane, not far outside, the unpretentious rock wall slowly opened, revealing a descending elevator room.
