During the meal, several people were unusually quiet.

It wasn't until all five people put down their chopsticks that Zhao Long on the other side spoke.

"Academician Liu, let me introduce you."

"This is Academician Fei Xiangfei from the Ministry of Information Security."

"This is Academician Fan Zengfan."

Zhao Long introduced Liu Cong to the two people sitting next to him one by one.

Seeing this, Liu Cong also took the initiative to shake hands with the three of them one by one.

"If there is nothing else, we can set off now." Liu Cong said.

"Okay, then I'll trouble you, Academician Liu."

Later, led by the vehicle in front, Liu Cong and Lieutenant General Li Hu came to the Information Security Department.

This place is located near the suburbs of Beiping City.

There are soldiers patrolling the area near the Information Security Department office building.

Led by the car in front, Liu Cong quickly arrived at the compound of the Ministry of Industry and Information Technology.

The buildings of the Information Security Department and the Chinese Academy of Sciences are roughly similar.

After getting off the car, Zhao Long and others took Liu Cong and Lieutenant General Li Hu to the building of the Information Security Department.

Soon after, several people got into the elevator and arrived at the third floor.

Under the leadership of Zhao Long, Liu Cong and others followed the corridor to a room.

The room was a little noisy. Liu Cong could hear the chatter inside from outside and didn't know what was being discussed inside.

"Academician Liu, please come in!"

Zhao Long opened the door for Liu Cong himself, and Liu Cong was not polite and walked into the room.

The moment Liu Cong entered, the chatter of the discussion suddenly disappeared.

What replaced it was shock.

"Academician Liu, why are Academician Liu here?"

"Academician Liu is my idol, why is he here?"

"I would like to call Academician Liu a scientific giant in China!"

"…………"

Everyone's first reaction when seeing Liu Cong was disbelief, followed by excitement.

"Academician Liu, they are so enthusiastic." Academician Fei on the side smiled awkwardly.

"It doesn't matter."

Liu Cong smiled softly, and then greeted these people warmly.

Most of these people are in their thirties.

Their eyes were firm and showed no sign of decadence.

"Academician Liu, please come in. We have something to discuss with you." Zhao Longcong said.

"Okay, let's go in now!"

Just like that, the five people entered the office under the gaze of everyone.

The office is very large, and there are two high-performance computers in it. This is very attractive to Liu Cong.

As an engineering man, who can refuse a gleaming 3090ti?

"Academician Liu, sit down!"

"I'll make you some tea!"

With that said, Zhao Long went to get tea from the cupboard.

Academicians Fei and Fan arranged for Liu Cong and Lieutenant General Li Hu to sit down.

Since none of them were very familiar with each other, Liu Cong didn't know what Zhao Long's purpose was for calling him here this time.

For a moment, there was a bit of embarrassment in the air.

Finally, Academician Fan on the side broke the deadlock in advance.

"Academician Liu, is this your first time coming to our Information Security Department?"

"If there is somewhere you want to visit, just tell me and I will take you there!"

Academician Fan was very enthusiastic.

"Academician Fan, you're welcome to Liu Cong."

"Let's get down to business first and leave the visit later."

At this time, Zhao Long also came over with tea.

Not too many bells and whistles, just a cup of green tea.

As a science and engineering major, few people use tea sets to cook and drink tea.

"Hey, okay, thank you!"

Liu Cong stood up and took the tea cup with both hands to express his gratitude.

Seeing that Liu Cong had no airs, Zhao Long respected Liu Cong a little more in his heart.

"Academician Liu, and the friend next to me, we don't have tea sets in the office, so we can only use this to drink tea. Please forgive me if the reception was not good!" Zhao Long said apologetically.

"Don't say that, this is good!"

Liu Cong smiled at Zhao Long and others, then picked up the tea cup and took a sip, exclaiming: "Good tea!"

"Yes, good tea."

Lieutenant General Li Hu on the side also echoed.

Seeing that neither of them cared that much, Zhao Long did not continue the pleasantries.

"Then we can get down to business now."

Liu Cong nodded: "Well, let's start now."

"I'm also curious about why your Information Security Department suddenly came to me."

Having said this, the faces of the two academicians next to them were filled with sadness.

"The reason why we asked you to come here to help is because Guofangbu recommended you."

"We just couldn't think of any other way to find you."

As Zhao Long talked, there was still a little smile on his face, but now it is all gone.

"Um?"

"What's going on? Can you tell me?" Liu Cong said.

As he said that, Zhao Long glanced at Lieutenant General Li Hu next to Liu Cong.

After Liu Cong indicated that it was one of his own, Zhao Long relaxed his vigilance.

"Liu Yuan, why don't I avoid it first?"

Lieutenant General Li Hu knew it well and planned to leave on the spot.

"No, let me introduce to you. This is Li Hu, Lieutenant General Li of the Peking First Military Region."

"Everyone is their own person."

Hearing what Liu Cong said, Zhao Long deeply apologized for his behavior just now.

"Lieutenant General Li, I'm really sorry. Look at my brain. I didn't even ask you about your identity in the first place."

"I didn't mean to drive you away just now."

Zhao Long looked at Lieutenant General Li Hu with some embarrassment, but Lieutenant General Li Hu didn't care at all.

"It's okay, I understand."

In the end, under the strong request of several people, Lieutenant General Li Hu chose to listen on the sidelines.

"Academician Liu, it's like this. We recently discovered a very difficult problem."

"We found that spies from the United States have penetrated deep into China, and may be suspected of spying on military intelligence."

"However, no matter how we tried to decipher their location, we found nothing. We didn't know what to do, so we went to ask Guofangbu, but the people over there were just like us, and there was nothing we could do!"

"Finally they gave me your contact information and asked me to come find you!"

"so……"

When Zhao Long said this, Liu Cong already understood what he meant.

"Director Zhao, do you want me to help you decipher the information?" Liu Cong asked.

Zhao Long nodded, "Since the beginning of this year, we have discovered a large number of suspicious packages and objects at sea and on land."

"Fortunately, due to inspections by customs and border crossings, many packages were intercepted in advance, so no big mistake was made."

"But there are still some that we cannot investigate, because many of them are living as ordinary people in China."

Speaking of this, Zhao Long sighed.

"In the past, they basically used Morse code and barrier cipher encryption. Sometimes they also used three-point cipher. It was only a matter of time for us scientists to decipher it."

"Now these few times, our superiors have begun to pay attention to this matter and summoned a large number of talents to prepare to decipher their codes. However, no matter what we do this time, it will not help."
