At Liu Yi's suggestion, the intelligence department and the fleet quickly took action, took several smuggling groups in one go, and severely interrogated these people.

The smugglers quickly relented, and with the help of the intelligence services, they finally agreed to cooperate with the intelligence services to take several agents to the outpost space station where the smuggling transaction was conducted.

With the cooperation of the smuggling cartel, the operatives managed to infiltrate the outpost and find a way to stay there.

This outpost space station was originally used for various observations and monitoring, but now the imperial capital is in a state of warlord melee, and discipline in the army has been much lax.

So the officers of the space station used their brains to take advantage of the location of this space station and turned it into a place for smuggling transactions.

According to the reports of the agents, the space station has a good expansion, so the garrison officers have expanded the space station, so that the space station is several times larger than the original, and it has become an exchange.

The station is home to a number of smuggling ships that come and go every day, and smugglers from all over the empire and the imperial capital trade here.

The goods traded range from all kinds of common commodities to all kinds of arms and weapons, and there are even all kinds of smuggling businesses to help people in the imperial capital or people from outside enter and leave the galaxy.

When Liu Yi saw these reports, he couldn't help but smile dumbly, and said secretly in his heart: "The officer of this space station is also a talent, which is almost the same as what I did in the White Rock Fortress. ”

It's just that the officers of this space station are still not as bold as Liu Yi, although they have set up such a smuggling trading point, he doesn't dare to let ships into the galaxy casually after all, and the space station itself is not armed with ships.

Liu Yi praised the intelligence department and encouraged them to make persistent efforts to open a breakthrough from this space station and obtain useful military intelligence as soon as possible.

I have to say that the intelligence department is ruthless this time, and must do something to show Liu Yi, and the few agents sent are the elite of the elite.

These people are not only highly skilled, but most importantly, they have a special set of speaking and doing things, and they have not been on the space station for long, and they have a clear understanding of all kinds of doorways.

Not only are the agents familiar with the station's garrison, but they are also connected to the station's officers through the soldiers.

From the officers, the agents learned that the defense system of the imperial capital was still functioning, which was the key to the imperial capital being able to close its doors, and even those warlords who were constantly fighting understood the importance of the defense system.

However, it is not clear to these junior officers who are in control of the defense system now, and only those with relatively high ranks may have access to these secrets.

Agents sent instructions to the headquarters of the intelligence services, asking them to be allowed to follow the path and gain access to higher-ranking individuals in order to obtain more information.

The intelligence services agreed to the agents' request after discussion, and promised them that they could use a monetary offensive if necessary, even if it was a bribe, as long as they could get useful military information as soon as possible.

The agents received greater support, and immediately let go of their hands and began to launch a monetary offensive against the officers of the space station, which worked very well, and the officers of the space station fell one after another, and they all became the iron buddies of the special agents.

Through the matchmaking of officers on the space station, an agent becomes friends with the superior officer of the space station, and then continues to develop into a higher officer......

After just two months, the agent managed to hook up with a colonel officer who specialized in checking the defense system, and gained a lot of useful information.

At the same time, several other agents have developed their own sources of information and information, and one agent has infiltrated the Imperial Capital with the help of the Imperial Capital Smuggling Syndicate.

The agents learned from the colonel officer that the Imperial Capital's defenses were currently working well and were not in a state of disrepair.

Although the imperial capital is now in a state of warlord separation, these people are very clear that the defense system is their talisman, so they have reached a tacit agreement that they will continue to be responsible for the maintenance and operation of the defense system without destroying or intervening in the army and departments that were originally responsible for the defense system.

At the same time, the amount of money spent on the defense system has not decreased, so the defense system has remained the same as it was, but it has not been further developed.

This information is very useful, so that Liu Yi and the others' strategic team can finally determine that the defense system is still effective, but no new super weapons have appeared, and the most powerful weapon is still the Houyi cannon.

However, the distribution of weapons in the defense system is still a problem that bothers everyone, and if the distribution of these defensive weapons is not clarified, the fleet will not dare to rashly enter the galaxy where the imperial capital is located, otherwise as long as it is hit by a Houyi cannon, I am afraid that half of the fleet will disappear directly.

So this difficult task was still entrusted to a few agents, and the intelligence services demanded that no matter what they could do, they must have access to the information on the distribution of defenses.

These materials are classified as top secret, and it is impossible to obtain them through ordinary channels, and even the colonel, who has revealed a lot of information, does not have access to all the materials.

After a lot of hard work, the agents still have a feeling that they don't know where to start, after all, such an important secret, unless it is the core of the army, how can ordinary people have access to it.

The intelligence department reluctantly reported these situations to Liu Yi, and Liu Yi did not blame them after hearing this, it is almost impossible to complete this kind of task in a short time, unless it is possible to do it even a little bit after a long period of infiltration.

After sending away the people from the intelligence department, Liu Yi couldn't help but recall the scene when he followed his teacher Yu Wensong to design the defense system.

The defense system of the imperial capital is a very large project, which began to be built many years ago, and is constantly being upgraded, renovated and redesigned in the process of construction, so it can be said that this is an endless engineering project.

At that time, although Yu Wensong was one of the most important designers, he was only responsible for part of it, and Liu Yi worked under the teacher, and the core content he could access was even more limited.

Liu Yi thought back to the people who participated in the design at the beginning, and suddenly remembered that there seemed to be several group photos at that time, and maybe the people who participated at that time could be found through the photos.

Thinking of this, Liu Yi immediately activated the portable system and asked the artificial intelligence to find some photos and images at that time.

After several hours of searching, the portable system finally found the photos at that time, and the process was more responsible than Liu Yi imagined.

It turned out that Liu Yi himself had already deleted the photo, and the portable system was through various methods to back up the data at that time, and after searching for a long time in the data like the sea, he found the photo.

Looking at the people in the photo, Liu Yi's heart was full of emotion, many of the people in it had left this world, including his teacher Yu Wensong.

"Things are not people...... Liu Yi sighed, and there were tears in his eyes.

However, Liu Yi didn't stay in the mood of reminiscing for too long, now is not the time to remember the past, he has to hurry up and do the right thing.

Liu Yi put away his memories and asked the portable system to investigate the current situation of everyone according to the people in the photo, and if he could find some of the people who participated in the design, he might be able to find some useful clues.

However, it is very difficult to find such people in such a large population of the empire, even with the help of powerful artificial intelligence, and some of them have long since been heard from, and perhaps even their data has been destroyed.

Liu Yi did this just as a dead horse as a live horse doctor, so he could only hold the mentality of giving it a try, he could find a better one, and if he couldn't find it, forget it.

After handing over this work to the portable system, Liu Yi no longer cares, and if there is a result, the portable system will naturally feed back to Liu Yi.

The busy affairs made Liu Yi quickly leave things behind, in fact, he didn't have much hope from the beginning, after all, so much time has passed, and the situation has changed drastically, thinking of how easy it was for these people back then.

However, things in the world are often intentionally planted flowers that do not bloom, and willows are planted unintentionally, and a few days later, Liu Yi suddenly received feedback from the portable system, and the search for those people in the photo actually had results.

Liu Yi was very excited, he really didn't expect to really find clues, so he immediately put down his work and began to check the results of the search.

Most of the people who participated in the design of the defense system have passed away, and some are missing, and it is unknown whether they are alive or dead.

At present, there are about four or five people who are still alive, including Liu Yi, and only one of these four or five people who has really served important tasks is named Li Mingheng, who belonged to the Imperial Capital Royal Design Institute at that time and is the main designer of the overall structure of the defense system.

This person's experience is somewhat similar to that of Yu Wensong, and he was also secretly detained, and later Yu Wensong and these people became missing, and only this Li Mingheng was still alive.

Liu Yi didn't know how he survived, many scientists who had mastered military secrets were persecuted at that time, maybe it was Li Mingheng's luck, in short, he is not only alive now, but also living in the imperial capital.

Liu Yi couldn't help but be overjoyed, and said in his heart: "If you can find this Li Mingheng, you will definitely be able to get a lot of useful information, and maybe you can know what happened to the teacher at that time!" ”

"Let the head of the intelligence department come to me right away, the sooner the better!" Liu Yi pressed the call button on the table and said to the secretary outside.
