After staying in the Unicorn Fortress for half a month, there was no grand occasion of countless warships fighting in the air and the New American Army pressing on the Unicorn Fortress as Yun Yi imagined. The army of the new America did not know where it was, and not even a shadow was seen. At this time, the fleets gathered around the Unicorn Fortress, in addition to the six main fleets left behind in the original fortress, there were also the ten main fleets brought by Lin Jiaoyang, the two local fleets, and the two main fleets sent by Qin Shou. Of course, there are also several transport fleets, and all kinds of supplies are constantly being transported from all over Chu and Tang to the Unicorn Fortress.

As for the crown prince Chu Xiuling, who represented the Chu Tang royal family, he did not send any fleet, not even a single one.

He didn't give any explanation for this, and Lin Jiaoyang and Qin Shou didn't mean to ask. Only Bleteg occasionally whined and said something to complain about Chu Xiuling. In his opinion, whether it was Lin Jiaoyang or Qin Shou, or the left-behind fleet of the fortress, everything they did was to protect the safety of the entire Chu Tang. As the ruler of Chu Tang, Chu Xiuling didn't say anything, and didn't even send someone to condole, which made Blaiteg very angry.

However, when Bletteg and Yunyi were chatting again, they were heard by Lin Jiaoyang, who was passing by, and after being reprimanded fiercely, Bletteg no longer dared to talk nonsense.

In the past half a month, in addition to hiding in the room to design mechas, Yun Yi has wandered around the fortress.

Arguably the most outstanding man-made structure in the universe in the past 50 years, from the inside out, whether it's the gigantic cannon or the small screw in the internal parts, it has an unparalleled attraction for mechanical engineering experts like Yunyi.

With the highest-level pass issued to him by Lin Jiaoyang, Yunyi could walk unhindered in every corner of the fortress and observe his curious location. At the same time, he also has part of the authority of the fortress master [Qilin], and with this permission, he can connect with [Qilin] through the light brain, and check the structure and technology used in the construction of the fortress. Although this fortress has been built for more than half a century, the technology used inside is the most apex in the universe. Through viewing, the technical level of Yunyi has risen a lot, and there are many extremely ingenious designs in it, after careful consideration, Yunyi's eyes are opened, and he is no longer limited to the previous realm.

From his observations, he found a lot of useful techniques and techniques that could be applied to the design of mechas. In this way, the time for mecha design has also been greatly shortened, and Yun Yi himself estimates that it will not take more than a year at most, and the mecha used by the mecha cavalry regiment can basically be designed and formed. At that time, the Nebula Group was entrusted to manufacture several test products for various pressure tests, and then it could be put into production in large quantities.

On this day, Yun Yi connected the light brain to the fortress's network in his room, and after using his permission, he re-entered the database of the fortress light brain [Qilin], and looked through the design materials and blueprints of those fortresses. Just as he was engrossed in looking through it, his heart jumped, and he looked around, but there was no one around, the whole house was empty and extremely quiet, and it was only him.

"Is it my delusion again?" Yun Yi muttered to himself, a little confused in his eyes.

These days, he always has a feeling of being stared at. This is the feeling that occurs in your room, during a meal, when you are out and about, or when you are talking to someone. However, each time it was instantaneous, and it would disappear in no more than a second, making Yun Yi wonder if there was something wrong with his sensory system. Uneasy, he often took the Syrophy ribbon with him.

Born into the Dragon Slayer, Syrophys is highly trained in the art of stealth assassination, and her instincts are excellent, a must-have for an Assassin.

But even if Sherumis was next to him, he would occasionally give Yunyi the illusion of being watched. Ask Syrophys, but the girl shakes her head, saying that she doesn't feel anything. In this way, Yun Yi was completely helpless, and could only attribute it to the illusion that he was too tired these days.

It's just that this feeling appears from time to time, which makes Yun Yi extremely uncomfortable. Sometimes, especially when he is concentrating on the design work, this feeling suddenly appears, which will always disrupt his thinking, and he finally thinks of a solution to a certain problem, but because of this interruption, he forgets it completely, and can only sit down and continue to think.

Glancing at the seemingly unfamiliar data on the screen, Yun Yi sighed helplessly, closed his eyes slightly, and pressed his hands on his temples.

The blue light in the room flashed suddenly, and a round light brain core appeared on Yun Yi's hand.

"[Sakura], I don't know if you're okay living in it?" Yun Yi muttered to himself to the light brain core in his hand. It's been more than a year since [Sakura] fell asleep, and there is no movement in this light brain core where [Sakura] is stored. Yun Yi sometimes wonders if [Sakura] has completely disappeared from this world.

If [Sakura] is here, he will definitely be able to analyze whether his feeling is real or Yunyi's illusion.

He flipped through the light brain core in his hand for a while, until Yun Yi was sure that it was no different from before, and then he planned to put it back into space. Only in the free necklace that he carries with him will Yunyi feel safe.

The blue light flashed again, and just as Yun Yi put the light brain core into him, he suddenly felt a wave of fluctuations coming from the palm of his hand.

"It's ......"

Frightened, Yun Yi hurriedly closed the space necklace, held the light brain core in front of his eyes, and watched it carefully with wide eyes.

A few minutes passed, and the appearance of this light brain core and Yunyi's memory did not change in the slightest.

"Is it my delusion again?" Yun Yi frowned slightly, if it was really an illusion, he came so often, was there something wrong with his body?

After thinking about it, Yun Yi did not put the light brain core into the space, but placed it next to the light brain and no longer touched him.

After a short break, Yun Yi put his hands on the keyboard and continued the design work of the mech. After a while, Yun Yi's attention was completely focused on the screen of the light brain, forgetting everything around him. Yun Yi, who was engrossed, didn't notice that the light brain under his hand was emitting a trace of invisible data outward, and the direction of the shot was the light brain core placed next to the light brain.

After receiving these data, extremely subtle fluctuations were generated from the light brain core, and soon, a trace of extremely weak data diverged from the light brain core, which was captured by the light brain next to it, and through the connection of the network, it was only an instant to reach the core of the network.

At this moment, in the very center of the Unicorn Fortress, that is, in the middle of the [Qilin] main engine where the most important part of the fortress was located, above the huge main engine that was nearly 100 meters high, a slight humming sound sounded. Countless indicators flashed wildly, whether it was alarm lights, indicator lights, data lights or lights, they flashed uncontrollably, turning on and off, off and on, shining in the entire computer room.

There was no one in the machine room, and for the safety of the [Qilin], the garrison of the fortress strictly forbade anyone to enter it. For only one day a year, hundreds of opto-brain engineers, under the watchful eye of thousands of soldiers with loaded guns, inspect the [Kirin] and replace the old parts. But now, more than two months have passed since the last inspection, and naturally there is no one here.

As for the cameras installed all over the house, they didn't work for some reason, and what they showed was the same as before.

No one knows what happened in the computer room, in the entire fortress, or the same as before, everyone is doing their own thing, and no one will notice the changes in the computer room.

The host of [Kirin], in the midst of countless flashing indicators, the temperature is slowly rising. The rate of rise is not fast, but it is constantly rising.

As the top priority of the entire fortress, the cooling system of [Kirin] is also excellent, fully automatic control, which will detect the temperature rise of the main engine and release cooling substances at the same time. But now, dozens of cooling devices have begun to work, but the temperature of the [Kirin] host has not decreased in the slightest, and is still slowly rising.

100 degrees ......

200 degrees ......

500 degrees ......

If someone sees the temperature indication in the computer room at this moment, they will be surprised that their eyes are about to fall off. Because in the historical history of the fortress, this huge light brain has never reached such a temperature, even when Chu Tang attacked in a big way, the light brain controlled all weapons, including the main gun, and the calculations performed per second required at least thousands of the most advanced central light brains in the universe at that time to be compared. Even in that case, the temperature of this light brain host did not exceed three hundred degrees. But now, it has actually reached 500 degrees, and it continues to rise.

When New America made this optical brain, it took into account the temperature problem caused by excessive computing. Therefore, the materials used for this optical brain are all resistant to high temperatures, even if the temperature exceeds 2,000 degrees, it will not cause any problems to the optical brain host. Later, when Chu Tang repaired this optical brain, the materials used were even better than Chu Tang's, so that the high temperature resistance value of the host reached 3,000 degrees.

Even if it is a high-temperature resistant material, coupled with a super cooling device, it is not possible to reduce the temperature of the host of [Kirin] even a little bit.

800 degrees ......

1000 degrees ......

Fifteen hundred ......

If something goes wrong with the Kirin, the entire fortress will be completely paralyzed. Not only is the "Unicorn Horn" cannon unfiring, but other weapons are also unusable. Even the various facilities in the base, as well as the passages to enter the inside and outside of the fortress, are very likely to be completely closed and locked due to the failure of the optical brain. If such a problem really happened, it would mean that half of Chu Tang's troops stationed in the Unicorn Fortress, including Lin Jiaoyang and other senior officers, would be completely sealed inside the fortress.

But no one knows about the problems that have happened to [Qilin] now.

Only those who may use the [Qilin], such as the monitoring department of the Unicorn Fortress, the internal system control department, etc., may find that the connection between their optical brain and the [Qilin] has slowed down. Most of the slowdowns in the system were caused by a malfunction of the optical brain, so they didn't suspect that something was wrong with the [Kirin].

There was no one who went to the computer room to check.

If New America launches an attack at this time, with the current state of [Kirin], the activation speed of "Unicorn Horn" will be at least two or three times slower than usual. If the temperature continues to rise, causing the [Kirin] main engine to burn down, then everything will become a disaster.

And the culprit who caused all these changes was still placed next to the light brain by Yunyi.

Sitting in front of the light brain, Yun Yi sometimes tapped the keyboard quickly, sometimes browning his brows, thinking hard, but he didn't want to include the light brain core in his space necklace.

1800 ......

2,000 degrees ......

2,200 ......

When the temperature rose to 2,500 degrees, in the entire fortress, all the light brains that were connecting with the [Qilin] were disconnected from the [Qilin] at the same time. At this moment, the entire fortress suddenly became chaotic.

Losing the control of the [Qilin], the ten entry passages began to slowly close. This is not operated by the fortress personnel, but the automatic protection system of the fortress's backup system after detecting that it cannot connect with the [Kirin]. Heavy alloy valves slowly stretched out from both sides of the inner wall of the channel, snapping into each other, and the overall thickness exceeded 100 meters. With such thickness and hardness, even if it is bombarded with the main guns of flagship-class battleships, the effect is extremely limited.

This is just one of the many changes that have changed since the Kirin lost control.

Without the automatic control of [Kirin], first, the various living areas and industrial areas in the fortress began to have a large-scale power outage. Because it was in the interior of the planet, the entire area suddenly became dark during the power outage, and you couldn't see your fingers.

Then, don't interrupt the communication connection between the inside and outside of the fortress, because people outside can't know all the news inside the fortress, and people inside can't send communications.

And the most frightening thing is that the huge "Unicorn Horn" located at the north pole of the Unicorn Fortress is slowly rising from the inside of the fortress, and the cannon muzzle that is so thick that even small ships can sail into it is flashing with a dazzling blue light. In the spaceship parked outside the fortress, every soldier and officer looked at the behemoth that was rising in amazement, as they served in the main fleet of Chu Tang, they naturally knew very well what the blue light represented.

"What, the Unicorn Horn is being charged?"

In the room, Lin Jiaoyang stood up, and his face became extremely ugly.

An officer with sweat on his head said quickly, "Yes, Lord Marshal. The subordinate is the supervisor in charge of the first energy base, after the large-scale power outage just now, the subordinate was about to take people to check the energy supply line, and he saw that all the fusion power furnaces in the energy base were all started without human control, and all the energy flow direction pointed to the horn of the unicorn of the main gun of the fortress! ”

Lin Jiaoyang's face instantly turned pale, and before he could speak, another officer broke in without even knocking on the door.

"Marshal, something is wrong, the unicorn horn is rising!"

Looking at the visitor, Lin Jiaoyang only felt that his heart was sinking rapidly. The officer, whom he also recognized, was the supervisor in charge of the maintenance and defense of the main gun, Unicorn's Horn. The main cannon is starting to rise and is being charged, which is a clear sign that the main cannon is about to fire.

And now, there is no New American fleet outside at all, all of them are Chu Tang's fleets, and all of them are in a state of engine shutdown. The battleship starts its engines, which takes at least ten minutes. The 'Unicorn Horn' is recharged in fifteen minutes. But even if those ships started to start their engines now, the remaining five minutes would not be able to get them out of the range of the fortress's main guns.

Not to mention the destruction of all the warships outside, even if only a small part of them, the consequences would be extremely serious.

The control of the fortress is now in Lin Jiaoyang's hands. But the fortress suddenly attacked the Chutang fleet, what would others think. I'm afraid that everyone in those fleets, from commanders to small soldiers, will think that he, Lin Jiaoyang, has taken refuge in New America, and his name is this unicorn fortress and the Chutang fleet that was bombarded and killed by the main artillery of the fortress......

With a "poof", Lin Jiaoyang sat on the sofa, lost focus in his eyes, and looked at it blankly. In just an instant, Lin Jiaoyang was as if he was more than ten years old, a few wrinkles quietly crawled on his face, and his temples turned gray.

The door was pushed open again, and this time it was not one person, but seven or eight middle-aged and elderly people, who seemed to be of different ages, but on their shoulders there were countless stars shining brightly, even in an office that had lost its power and was a little dark with only a few light-emitting devices.

"Marshal Lin, I hope you can give us an explanation!"

As soon as he entered the door, a middle-aged general shouted to Lin Jiaoyang aggressively. But soon, these people noticed Lin Jiaoyang's changes, glanced at each other, and they all showed deep surprise. They can see Lin Jiaoyang every day, so they naturally know what he looks like. And now this person who looks like he is in his fifties and looks a little old, is it really Lin Jiaoyang?

"This ...... What the hell is going on? ”

An old general asked, bewildered. Such a big thing happened in the fortress, these commanders and deputy commanders thought it was Lin Jiaoyang's ghost, so they all came to ask him for the crime, but they never thought that they would see such a scene.

The officer in charge of the First Energy Base who came in before whispered to them: "Marshal Lin was fine just now, but after hearing the news of the unicorn horn rising, it suddenly became like this. ”

Several veterans looked at each other, and they also guessed that this matter probably had nothing to do with Lin Jiaoyang. But there are a few middle-aged generals who don't think so, maybe in their opinion, this is just Lin Jiaoyang's ghost, maybe that officer was also arranged by Lin Jiaoyang.

Just as they were about to continue the questioning, the office door was pushed open again, and another officer from the military academy ran in breathlessly.

As soon as he saw so many people, he was stunned at first, and then immediately shouted: "Marshal Lin, something is wrong." Due to the loss of energy supply, all oxygen generators in the base have been rendered useless......"
