The whole fortress is circular, the outer wall is hundreds of meters high, the width is more than 20 meters, and some places in the middle are hollow, so that people can be stuffed, and then through the small holes in the wall, they will attack the beasts that come to attack.

Because of the thickness of the wall, there are all kinds of heavy weapons on the top, whether it is against the air or the ground, they can ensure that they have absolute destructive power.

In addition, there is an airfield inside the fortress, and if it encounters an attack, the hovering fighters docked in the airfield can immediately take off to face the enemy.

Judging from this, the safety factor of this fortress is very high, and in this forest, they have the power to protect themselves.

However, the Blue Star people who came to the old land, what they needed to resist was not only those terrifying beasts, but also the ubiquitous magic sound, which was the most headache for them.

Therefore, the soldiers in this mountain forest, they are all wearing power suits, which have similar functions to the external mechanical skeleton, but are more advanced and have better effects.

You don't have to control or control this costume, it will automatically receive commands from your muscles and calculate the action you want to make based on a subtle change in your muscles, so as to help you jump or dodge.

And one of the most important functions of this power suit in the old soil is to help the Blue Star people isolate those magic sounds to a certain extent.

Because of the existence of power suits, Blue Star people can carry hundreds of kilograms of oxygen cylinders on their backs at will without feeling tired.

The existence of the oxygen cylinder can allow the Blue Star people to wear a glass cover on their heads for several days, or even ten days, to isolate the magic sound, so that they have the ability to march in the mountains and forests for a long time.

You must know that because of the power suit, under the rapid march, these Blue Star people will reach an astonishing number every day.

It was as Fang Yun had observed—through the ubiquitous cameras in the base, he saw columns of soldiers, wearing power suits and carrying a round transparent glass cover on their heads, constantly making rounds.

Boom.

At this time, a closed-wing rotary-wing combat transport helicopter rumbled over from the side of the World Tree, and when this helicopter was on the Blue Star, the Blue Star people had already made it, especially suitable for jungle flights.

The propellers on both sides replace the huge propeller overhead, and on top of the propellers on both sides are a protective device similar to an electric fan cover to prevent the propeller blades from hitting the branches.

As soon as the helicopter landed at the airfield, the special staff ran over and took out a large number of tendrils from inside.

Fang Yun looked at all this through the camera, and then his gaze fell on other places.

Suddenly, in his field of vision, a conference room appeared.

A meeting was being held in the conference room, the conference table was already full of people, and through the monitoring of the stereo and microphone, Fang Yun heard those guys speak.

First of all, it needs to be explained that the situation of these guys in the conference room, sitting in the first place is a middle-aged man with a flat head, his figure is so burly that it makes his head look a little small, judging by the color of his skin, he is a white man, but his skin is a little tanned.

He was wearing a camouflage uniform, and his eyes looked resolutely at a middle-aged man in front of him - this man wore a pair of gold-rimmed glasses, and his complexion was fair, not like a man in the army, but more like a pampered figure.

"Chief Miles, I think we need to discuss when we're going to enter the Exclusion Zone to rescue our company's research team, they've been in the Exclusion Zone for ten days."

The man with gold-wire glasses asked eagerly towards the burly middle-aged man in front of him.

"Mr. Lee."

Miles said to the man in gold-wired glasses: "I can understand your feelings, but I also hope you can understand us, there is no corresponding order from above for the time being, and I have no right to send people over - even if we are only a hundred kilometers away from that devil-like place!" ”

For the current Blue Star people, 100 kilometers is a very short time.

"But our company's research team responded to your call, but now we can't contact our people, and you turn a blind eye when you need your help."

"Maybe I should report this to my boss and let him talk to your boss over there."

"No, Mr. Li."

Miles groaned, and then said, "In this case, how about I send a team of fifty people to protect you to the restricted area?" ”

"The situation over there is mostly the damn magic sounds, and I'll give you the best equipment, and sturgeon oil."

"Li Sheng, I'm sorry, my rights are just here."

Li Liguo sat back in his seat, his brows furrowed, he also knew that although Miles was the highest commander here, it was completely impossible to send a large army into the forbidden area.

If his superiors knew about this, they would definitely collapse him.

The forbidden area has now been lifted, but there is no army to go to that continent, but some research teams have been called to explore the way to that continent.

Coincidentally, their company's research team also began to enter the area after learning the news.

Initially, it was agreed that the research team would only operate around 30 kilometers and send messages with flares every three days.

However, it has been a week since the last time their research team sent a flare, and it is clear that the research team has lost contact.

Li Liguo came to the Black Iron Fortress, hoping that Miles could help them enter the forbidden area to find their company's research team, but Miles refused to answer.

After losing contact for a week, it is very likely that he has died inside, and the situation over there, Miles knows better than anyone else, and it is very likely that they sent people over, and it is very likely that they will also end up in a dead end.

Under various considerations, Miles rejected Li Liguo's request, but Li Liguo is not small, even he has to be polite, and according to Li Liguo, there is an important person in their company in the research team.

Miles is now scolding his mother in his heart, and it is not he who calls for the domestic research team to enter the forbidden area, it is those old guys at the top, but now he is going to let him carry a pot.

"Chief Miles, when is the operation going to begin?"

Taking off his glasses and rubbing his brows, Li Liguo suddenly looked up at Miles.

……

"The current Blue Star people have begun to explore the forbidden area."

Fang Yun couldn't help but be surprised, "Why are they suddenly so interested in the forbidden area?" ”

In the previous time, although the Blue Star people were curious about the forbidden area, they were more of a jealousy, so they had no intention of exploring the forbidden area for the time being.

Unexpectedly, in just five years, they actually began the initial action of exploring the forbidden area.

Fang Yun entered the information system of the "Black Iron Fortress", and then carefully rummaged through the corresponding information, and after some searching, he really let him find the relevant information.

And after reading this piece of information, he couldn't help but be even more surprised.

The reason why the Blue Star people couldn't wait to explore the forbidden area was because they had received some information from the World Tree.
