Hearing the word sapper, there was no need for Yang Tie to explain it again, Xiao Wuchen had already literally understood what kind of soldier this was.

Arms were called sappers in the Xia military, and they were specialized in the production and creation of weapons, and they were called sappers.

Because this branch of the army does not have to go to war, their main task is to create weapons and research equipment.

It is more like a worker in nature, so it is called a sapper.

In other countries, they also have their own names, but they are all called arms internationally.

Could it be that my manuscript of the exam drawings was sent to the Engineer Research Division? Xiao Wuchen guessed in his heart.

Only this explanation is more reasonable, otherwise how could the people in the engineering department look at him as a combat unit.

This also corresponds to what Wang Tie said just now, that is, special forces will not be favored by them, because they need people who create weapon talents, not excellent special forces.

"Is my exam blueprint in your hands?"

"Yes, your reaction is not very slow, so you can't refuse my invitation, we need to go to you to do the confidential work, otherwise with the importance of the drawings, you may really be put in prison to prevent the secrets of the drawings from being leaked."

"I'll rub!"

"It's my fault too!"

Xiao Wuchen was speechless.

"It's not your fault, it's the weapon ideas and data in your head."

"It can be important, and if the weapon design can work, then your importance is self-evident."

"In order to prevent you from leaking these design secrets to the enemy, we really risk imprisoning you and putting you in prison."

Xiao Wuchen really wanted to say something special, isn't this still my fault!

Fortunately, Yang Tie told Xiao Wuchen that as long as he obediently went with himself to see the old man he said, otherwise everything would be uncertain.

There is only one engineering research institute in the Jingye Military Region, and it is still in Beijing.

Returning to the city again, Xiao Wuchen felt a little like a different world, as if he had just returned from the wilderness.

The prosperity of Beijing can be said to be one of the best cities in Xia Kingdom, and there is so much history and culture here.

Beijing is like the dragon vein of the Xia Kingdom, carrying the national fortune and inheritance of the entire Xia Kingdom.

Yang Tie did not drive the car towards the capital city, but walked on the periphery of the capital city, and it didn't take long for a gate to fall into Xiao Wuchen's eyes.

"Tang's Military Industry Research Institute" is engraved on the plaque, which looks majestic and bold.

Named after the beginning of the Tang Clan, Xiao Wuchen already understood that this was an inspirational attempt to learn from the most powerful dynasty of the Xia Kingdom.

Because the Tang Dynasty was the most prosperous founding dynasty in the history of the Xia Kingdom, it can be said that it was extremely powerful in unifying the eight wildernesses, and the weapons created at that time were also the most advanced and most historical era, and it was able to lead the world for a hundred years at that time.

The Military Research Institute is very quiet, and the nearby kilometers belong to the territory of the research institute, which is guarded and protected by soldiers, and has a high city wall, like a great wall, and ordinary people can't enter it at all.

When the vehicle drove to the main entrance, Yang Tie and Xiao Wuchen were asked to get out of the car, and several guards and soldiers used some reconnaissance instruments to scan the car back and forth.

At the same time, Xiao Wuchen and Wang Tie were also searched by the instrument, and after confirming that they were correctly identified, the two were released.

It is worthy of being an important place in the Military Research Institute, Xiao Wuchen sighed in his heart.

Entering through the main entrance, they were scanned by electronic instruments at least three times.

There are not many security checks of this level, and the first time Xiao Wuchen encountered it, it is enough to show the status and importance of this military research institute.

It is almost impossible for foreign spies to enter the military research institute through the main entrance, and no one can get in unless they attack by force.

The car stopped, Yang Tie got out of the car with Xiao Wuchen, and headed towards the office building of the old man in his mouth.

The so-called office building is also the research institute.

Xiao Wuchen found that there were not many people inside after coming in, and there was no sense of crowding.

At this time, a middle-aged man passed by Yang Tie, and when he saw Yang Tie, his face was happy.

"Lao Tie, I heard that you were on a business trip, and you came back so soon?"

"Of course, I have to come back as soon as possible, there are still many things for me to do!"

The man nodded.

"Who is this?" He moved his gaze to Xiao Wuchen beside Yang Tie, and asked with questions in his mouth.

"His name is Xiao Wuchen, a recruit of the armored regiment of the Jingye Military Region."

"Hello," the other party just took care of Xiao Wuchen briefly, and then looked at Yang Tie.

"Lao Tie came back and helped me figure it out, there are some details of my weapon design that I need your help to fix up."

"Okay, no problem."

"Remember not to release my pigeons this time, I'm busy first."

After saying that, the right person has left.

"Lao Tie!" Xiao Wuchen shouted as the other party learned.

"You kid."

Yang Tie deliberately glared at Xiao Wuchen, but he didn't expect his name to be exposed like this.

There's no way who made his name Yang Tie! After being with these colleagues for a long time, they will give each other nicknames to make it easier to shout.

So his name Yang Tie got such a well-known name as Lao Tie, which is easier to be remembered than his proper name.

......, the two of them entered the building, and a scanning ray flashed, and Xiao Wuchen instinctively took a small step back.

"Don't be nervous, it looks like a tight place, but that's just a necessary precaution against the enemy's prying eyes, and the people in us are very easy to get along with."

Xiao Wuchen nodded, indicating that he was not nervous.

He really didn't feel nervous, but had some anticipation in his heart.

Because from Yang Tie's words, Xiao Wuchen knew that the identity of the old man he was about to meet might be very unusual, and he was definitely a big man.

He used to be an ordinary ordinary person, and he never thought that he would meet the most important person in the country one day, and he was inevitably a little excited and expectant.

Yang Tie led Xiao Wuchen into the elevator.

At this time, Xiao Wuchen saw Yang Tie take out a pair of light blue eyes from his pocket and put them on, and then pressed twice on the flat glass on the side of the floor button, and then the elevator door closed and opened for operation.

Xiao Wuchen was a little puzzled at first, he didn't understand why Yang Tie was uneasy about the elevator button on the floor, but he had already guessed the answer in his heart when the elevator was moving.

Xiao Wuchen found that the buttons that could be seen next to him only had the number of ascending floors, but there was no basement floor marker, which was obviously used to confuse outsiders.

And the few times Yang Tie put his eyes on the glass just now, it should be the location of the design of the ultraviolet invisible underground floor button.

With this design, even if outsiders break into this place, they can't find the elevator button in the basement, and can only go to the building floor above the building.

Most of the important documents, such as the data on the results of weapons research, are completed in the basement and are kept in the basement.

This design also adds a layer of safety and security.

Sure enough, as Xiao Wuchen guessed, the elevator did not go up, but went down quickly.

Bang dang.

Dozens of seconds passed, and the elevator paused, and it had reached the underground floor where Yang Tie was going
