In terms of volume, the volume of the transport ship is arguably the largest of all ships. Even compared to the flagship-class battleship, it is nearly twice as large. The huge volume can make the carrier load more goods and reduce transportation costs.

But in terms of speed, the transport ship is the slowest of all ships.

I have experienced the high-speed commercial spaceship specially made by the blue sky, and now sitting in the military armed transport ship, Yun Yi even has the illusion that he can walk much faster than the transport ship. It's been almost a week since it set off, but the 21st Mixed Armed Fleet hasn't even gone out of the Weizhou Star Field, and is still flying leisurely and slowly. Since its departure, the spacecraft has been thinking about traveling in a southwestern direction, where it can pass through the long-distance XW01 wormhole and reach the Xingzhou Star Field.

At the current pace, in less than a month, this fleet will not want to reach the Unicorn Fortress.

Although he was anxious about the speed of the ship, the maximum speed of the transport ship was also like this, and there was nothing he could do in a hurry, so Yun Yi calmed down and locked himself in the room alone to study and design the mecha. A few days ago, he received a communication from Yin Ji, the dean of the Tower Shield Academy, and learned that in the more than two months since he left, there were more than 100 innate level mecha masters. Moreover, there are now more than 3,000 academies that have reached level ten, and it is expected that in the next half a year, the birth speed of innate masters will usher in a blowout, and they will spring up one by one.

Yun Yi knew that the design work on his side had to be accelerated, otherwise after the students had entered the innate level, they could only drive ordinary mecha purchased on the market to fight, and they would not be able to exert their due strength at all.

But fortunately, Yun Yi's foundation in mecha engineering is very solid, and during this time, as long as he has time, he will pounce in front of the light brain to carry out design work. The basic structure has now been prototyped, and at the current pace, it will be possible to complete the design within a year or two.

In addition to designing mechs, Cloud Wing occasionally urges Blue Sky and Lotus Card. The latter, on behalf of the United Family of the Cologne Merchant Alliance, provided him with rare ores mined from NW-AL0083, which were sent to a secret warehouse at the Tower Shield Academy to be sealed after Yunyi paid the corresponding amount of Imperial Gold Dollars. And the former, although Lan Tian is in charge of the extremely important artificial wormhole communication line during this time, but the construction of the rare ore smelting plant cannot be left behind, which is related to the use of rare materials when manufacturing mecha in the future, if the mecha warrior is also there, the mecha design is also available, and the factory that manufactures mecha is also available, but there are a few materials that cannot produce mecha, in that case, it is enough to make Yunyi depressed to death.

Lan Tian is still more concerned about the matter of the mining and metallurgical factory, and sent his capable generals to take full charge of this matter. Moreover, the location of the mining factory is in the Kingdom of Mayah, as one of Yunyi's best friends, Omir will also be very concerned about this matter and give a lot of help in the construction process.

According to Lan Tian's estimate, it will take half a year at most, and this large-scale space mining and metallurgical factory, which can be regarded as the first in the Southeast Universe, the fourth in Chutang, and the top ten in the Southern Universe, will be completely completed. When the time comes, whether it is the ore shipped from NW-AL0083 or purchased by Yunyi from other places, it can be transported here for processing to produce the rare materials he needs.

On the ship, in addition to designing mechas, Yunyi has to communicate with Lin Moxue every day. Although the delay in communication is getting bigger and bigger due to the distance, the two of them are happy to do it, as if they don't talk for a day, and they feel uncomfortable. Of course, Yun Yi mainly faked the information on the front line from Lin Moxue, so as to grasp the latest developments in the war.

Lin Moxue told him that now that the fleet of New America had gathered on the planet closest to the Unicorn Fortress, it had no intention of launching an attack for the time being, but began to build a military supply base based on this planet.

After learning about the movements of New America, Yun Yi was somewhat impressed by its preparations for a long-term war of resistance. It seems that there are also extremely outstanding generals, marshals or staff officers in New America, who can clearly analyze the current situation in Chu Tang. Presumably they already knew that the forces of Chu Tang who came to support the Unicorn Fortress were not as harmonious as they imagined. Although they are now forced to join forces to fight against the new America, if the time goes on, a long period of idleness and material consumption will continue to reduce morale, and naturally some people can't help but leave first, as long as one battleship leaves, there will be a second and third, until all the battleships that came to support the Unicorn Fortress leave, it is time to launch a general attack.

Therefore, the most unfavorable thing for Chu Tang now is the long-term battle plan of the new United States.

I don't know if Lin Jiaoyang has come up with a countermeasure, and Lin Moxue is not very clear about this, but he just told him that when he communicated with his grandfather, although his grandfather always had a smiling face when talking to her, the intelligent Lin Moxue could still catch a trace of sadness from it.

But right now, these things aren't for Yunyi to think about.

There is still almost a month to go before reaching the Unicorn Fortress, and it is not close to reality, so it is impossible to observe the actual situation of the Unicorn Fortress up close, and even Yunyi has no way to make countermeasures. Instead of wasting time thinking about how to defeat the fleet of New America, it is better to devote all of your time to the design of the mech.

On the eighth day of departure from the base, the fleet finally arrived at the entrance and exit of the XW01 wormhole leading to the Xingzhou star field in the Weizhou star field.

Compared with the bustling wormholes in the past, the flow of spaceships through the wormholes is obviously not as good as before. Although only a small number of people knew about Qin Shou's rebellion, and ordinary people did not know about it, it was this small group of people who were all people who stood at the pinnacle of Chu Tang's power or wealth, and most of the spaceships that usually passed through the wormhole were owned by these people. The current situation in Chu Tang made these people dare not act rashly, let alone conduct ocean trade as before. Maybe one day when the fleet goes out, it will be stopped by a warlord and packed up and taken away, and it will be too late to regret it.

After passing through the wormhole, after more than ten days of flight, and after passing through the wormhole for two days, the fleet finally arrived at the Juzhou Star Field, which was adjacent to the Guzhou Star Field, the Cologne Business Alliance, and the Yangming Kingdom, where the Unicorn Fortress was located.

Juzhou Star Domain is one of the eight star fields of Chu and Tang Dynasty, the only star field that does not border the Zhongzhou Star Field, where the capital Chang'an is located, is located cheaply, and people who come out of here will be jokingly called "hillbilly" no matter where they go. However, the Juzhou Star Domain is the only way for Chu Tang to trade with the Cologne Business Alliance, the Yangming Kingdom and various countries in the southeast, so the degree of commercial and economic prosperity is stronger than that of Xingzhou Star Domain and Weizhou Star Domain.

After coming out of the wormhole, the fleet will turn northward, and it is expected that it will take about seven days to reach the wormhole leading to the Guzhou star field.

Along the way, I didn't encounter any intercepting fleets, so it can be said that it was relatively smooth. And the wormholes they passed along the way were all in the hands of Lin Jiaoyang, and no one came to embarrass them.

However, seeing that this is about to reach the Unicorn Fortress, something strange happens.

On this day, Yun Yi was sitting intently in front of the light brain, studying the stability of an energy circuit. This problem was encountered by Master Niu before when he was designing the [Yi Xun] mecha, and he told Yun Yi no less than three ways to solve it. But now, Yunyi had a whim, to add another energy control system to this circuit, so as to better control the flow of energy. If this problem is solved, the mech's energy recovery time after unleashing the skill can be reduced by at least a quarter. This is extremely important and advantageous for the mecha cavalry regiment that is suitable for group battles.

It's just that it's not easy to solve this problem, Yunyi racked his brains and tried countless methods but didn't find a solution.

Just when he was extremely distressed, and even had an urge to kick the light brain in front of him over, he suddenly heard a rapid knock on the door.

Sighing, Yun Yi knew that he was a little impatient. This is the case with mecha design, and sometimes a small problem can trouble the designer for a long time. But if you go out and distract yourself from this time when you can't figure it out, maybe you will think of a problem to solve when the tendon in your mind turns. So Yun Yi didn't blame the person outside for disturbing his work, but opened the door very calmly.

Outside the door was a younger soldier, dressed in the uniform of the logistics fleet. As soon as he saw Yun Yi open the door, he hurriedly said, "Mr. Yun, something is wrong, Commander Zhang asks you to go to the command room immediately." ”

Yun Yi said strangely: "What happened, why didn't Commander Zhang send me a message directly?" ”

"If I could, I would have sent it a long time ago." The soldier's face was a little ugly, and he said, "Now the fleet has been surrounded by Michaels scattered by the enemy, and it is impossible to conduct any communication at all. ”

Yun Yi was slightly stunned, he had joined the army since he was a teenager, and he also knew Mie particles very well. In space, as long as Mie particles are scattered in a large area, the communication between the spacecraft and other directions can be blocked, and it is a very widely used thing in warfare. But he had never heard that the Mie particle could also block the internal communication of other people's spaceships, so after hearing this soldier's words, the first thought that Yun Yi had was that he was deceiving people, and the second thought was that Zhang Xintian's communicator was broken.

Thinking of this, he quickly turned on the communicator and sent a communication to Zhang Xintian.

When he saw the words "network outage", Yun Yi believed what the soldier said. Suddenly, he thought of the word "enemy" in what the soldier had just said, and then he suddenly realized: "You mean, we are being targeted by enemy warships?" ”

"Not targeted, but surrounded!" The soldier's face was a little anxious, and he urged, "Mr. Yun, you should go to the command room first." ”

Yun Yi didn't bother to ask more, and hurriedly pulled out his legs and ran towards the command room. Because he knew very well what would happen if a transport fleet ran into an enemy. Don't look at this fleet, which is called an "armed mixed fleet", but in fact, it is just an ordinary transport ship with some artillery and missile launchers, neither the necessary large-caliber main guns of warships, nor the catapult system of mecha and fighters, it is okay to deal with some small pirates who are not long-eyed, if they encounter the enemy's regular army, they can't run even if they want to run at the speed of a transport ship, let alone fight.

Running and running, Yun Yi suddenly thought of another question.

The fleet is still in Chutang, and it is obvious that the enemy cannot be the fleet of the New America. Moreover, Lin Jiaoyang and Qin Shou have already agreed to support the Unicorn Fortress, this fleet belongs to Lin Jiaoyang, I believe that as long as it is a military person, it can be distinguished from the code name at a glance, how dare they risk provoking a civil war to rob this fleet?

Thinking about it, the speed under Yun Yi's feet was not slow, and he ran quickly towards the command room. Some of the soldiers and crew members I met along the way, as well as the ship's staff and technicians, all had panicked faces. It seems that the personnel of these logistics fleets did not conduct a real big war. As he passed by the outward porthole, Yun Yi glanced at it, and with the naked eye, he could see a glittering patch in the distance, and the planet could not be so dense, it could only be a man-made object, and in this case, Yun Yi could already guess that it was the enemy fleet that targeted the warship he was on.

It's just that the example is too far away, even if Yunyi has an innate level 10 cultivation, it is impossible to see clearly what kind of spaceships those are at such a distance, and can only rely on the ship's detection system to see which side of the warships belong to.

"Detachment 1, can you hear it, please answer...... The first detachment, the first detachment ......"

"Second detachment, can you hear it, please come back to ......"

"Third Detachment ......"

As soon as he entered the command room, Yun Yi saw Zhang Xintian yelling at the communicator, and it seemed that there was a problem with the communication system of the entire ship, and it was impossible to contact other spacecraft. In this way, the command of the entire fleet was completely paralyzed, the people below did not know the intentions of the above, the fleet commander could not mobilize the detachment, the detachment commander could not command the battleship, and if the enemy took the opportunity to attack, he could not organize a resistance.

Looking at Zhang Xintian's sweaty shout, Yun Yi shook his head slightly, and said secretly in his heart: Fortunately, this guy is not the commander of the main fleet......

"Command with light signals!"

Yun Yi couldn't bear to see the fat man's anxious appearance, and reminded him beside him. This is also a measure that the fleet usually uses when it is impossible to contact but is relatively close. Using the flickering of lights to relay a few simple signals can let other ships know the Fleet Commander's intentions.

"yes, how did I forget that." Zhang Xintian patted his head and immediately asked people to use light signals to notify other spaceships to prepare to detour. After ordering everything, Zhang Xintian remembered the person who reminded him, and when he looked up, it was Yun Yi, and hurriedly thanked: "If it weren't for Mr. Yun's reminder, I'm afraid I wouldn't know what to do by now." ”

On this ship, Zhang Xintian can be said to be the supreme commander. Although he was only a lieutenant commander of the logistics fleet, he also held the power to keep almost everyone on board. But when this kind of thing happened, and the communication with other warships was cut off, he didn't have anyone to talk to. After thinking about it, he thought of Yunyi, because looking for a young man, but Lin Jiaoyang personally informed him and asked him to take this young man to the Unicorn Fortress. It can be seen that this young man named Yunyi is definitely not an ordinary person, and it is estimated that Lin Jiaoyang can come forward in person.

With such an idea, Zhang Xintian asked people to invite Yun Yi over, but he didn't expect to do him a big favor just after he came.

Yun Yi sighed slightly in his heart, and from such an incident, he could see what the quality of this fleet was. If Zhang Xintian didn't think of it for a while, but what about the other officers or soldiers under his command, if it is the flagship of a main fleet, once this situation is encountered, whether it is an officer or a soldier, they will immediately think of the light command signal, and everyone will remember clearly what the signal means and what it means. Look at the soldier who went to prepare the light signal, and also looked up what the signal meant on the light brain.

"It's nothing." Yun Yi said lightly: "What happened, where do those battleships belong?" ”

"It's a New American." Zhang Xintian said hatefully, and then switched the screen to the screen detected by the detection system, and sure enough, the thousands of warships that appeared on the screen were all Poison Falcon-class warships. This kind of battleship is the main military warship unique to New America, although Chu Tang also has this kind of warship, but almost all of them are placed in museums or laboratories of battleship research institutions, and they are not seen outside at all, let alone thousands of them appear at a time.

Coupled with the Michaels particles scattered around, what this fleet wants to do, Yunyi can already imagine it.

It's just that he doesn't understand where this new American fleet entered the Chutang transit. Although the Juzhou Star Domain was the most remote star field in the Chu and Tang Empires, the north and west were both within the Chu and Tang Empires, and the northeast was the Cologne Business Alliance, which never allowed warships from any country to enter the country; And in the southeast is Chu Tang's die-hard Yangming Kingdom, which is said to be a kingdom, but in fact, it has already become a puppet kingdom of Chu Tang, and everything must follow Chu Tang's instructions.

"Where did this fleet come from?" Yun Yitou asked without replying.

"I don't know." Zhang Xintian said hatefully: "I was still sleeping just now, and I was suddenly called up by my subordinates, and I saw that the enemy no longer knew when the Mie particles were scattered. Judging from the records, it must have been sprinkled with Michaels particles on this route before we got here, and we just didn't notice it and got headlong into it. Fortunately, the enemy's fleet is still some distance away from us, and we hope to have time to escape......"

Yun Yi frowned, at this time, he was not thinking about how to escape the starry sky, but why the fleet of New America was here, and there were Mie particles scattered along the route to isolate the signal.

Suddenly, he thought of a possibility, and couldn't help but shudder.

"Could it be...... Is there a long-distance wormhole from New America to Chutang? ”
