Siheyuan: My name is Cao Xing, and I have a strong background

"Mr. Liu, what does dead child mean?"

Cao Xing only had a general idea about the spy undercover business. It was a very complicated business and there were many things he didn't understand.

Mr. Liu explained: "The characteristic of this kind of dead child is that they do not pass on intelligence or contact their superiors, but they carry out various activities inside the target country, which has a profound impact on the political, economic and social environment of the target country. This causes great damage to the target country. This kind of dead child is the most dangerous and the most difficult to eliminate."

Cao Xing understood that the harm caused by this kind of dead child is that it is deeply hidden and difficult to identify. If he holds an important position, the damage he causes will be very serious.

“You mean to say that if the plane was sabotaged, then this person is the dead son of the Northwest Base?”

Old Liu nodded and said, "That's right. These dead men are extremely difficult to find. After all, they don't pass on any information, don't have a radio station, and don't need to inquire about any news. They are extremely hidden."

Upon hearing this, Cao Xing closed his eyes and carefully thought about the condition of the plane at that time.

This is no joke, and it can be disastrous if you get it wrong.

Besides, the plane he flew into the sea has crashed into pieces, so it is impossible to find it. He can only guess based on his memory.

After a while, Cao Xing finally opened his eyes.

He said with a heavy face.

"Mr. Liu, I can now confirm that the bolts on the landing gear showed signs of being pried open by humans. There are three landing gears in total, each of which lost a bolt. Therefore, I am sure that this was man-made and not an accident!"

When Mr. Liu heard what he said, he was immediately overwhelmed.

Today, the most important place in the whole of China is the 311 Project Base.

In the underground air-raid shelter of the old city, anyone who can enter must undergo strict inspection, and they may not be able to come out for a short period of time.

Under the 311 project team, there are three major research bases, including a No. 096 air-raid shelter research base in Sijiu City.

Another one is in the south, and the last one is the Northwest Research Base.

These three bases concentrate half of China's talents, including people from all walks of life. Although the management is strict, there is no guarantee who can sneak in.

Especially for a dead kid like this, there is a chance that he could sneak in.

Old Liu said softly, "These idiots usually don't carry out such dangerous missions. Their main mission is to achieve a certain goal through public opinion or their own influence. He didn't hesitate to risk being exposed to murder Lao Guo. He must know the importance of the information in Lao Guo's hands."

Cao Xing pondered and said, "That's right. Mr. Guo knew the importance of the information in his hands, and he rushed to Sijiu City without wasting any time. Therefore, this person must have known the content of the information in Mr. Guo's hands in a very short time. That's why he did it once and for all and modified the landing gear of the plane, so that Mr. Guo and the information would be burned into the sea of ​​fire."

Cao Xing quickly figured out what was going on and began to reason.

His mind worked quickly, and he soon realized that the guy was willing to take the risk because he was absolutely sure of his success.

After all, in this day and age, no landing gear means crash, no exceptions.

When the plane crashed, the people and information inside would naturally be lost. I have to say that this guy had a nice idea.

But unfortunately, Cao Xing was involved in this matter.

The people and the data were all safe, but the plane crashed, so the evidence was lost.

At this time, Han Weiguo walked in with the packaged roast duck.

"Commander, the roast duck has arrived."

Old Liu nodded repeatedly after hearing Cao Xing's analysis. He felt more confident and his expression improved.

"You should eat first, and then go and write the letter of guarantee."

"Ah? Still writing a letter of guarantee? Aren't you going to arrest people?"

Old Liu snorted and said, "Don't be so anxious. The person can't get away anyway. I'll go check it out myself later. The most important thing for you now is to eat. Besides, the letter of guarantee is the highest instruction. You can't discuss this with me."

Upon hearing this, Cao Xing nodded immediately. He thought to himself that the highest instruction actually asked him to write a letter of guarantee. He was still a little flattered that he was valued so much.

"Mr. Liu, you and Brother Han can eat some too. This is a whole duck."

He had just drunk a physical potion and was not hungry at all.

Han Weiguo picked up two more packaged roast ducks.

"You eat yours. I brought some for the chief."

Cao Xing was stunned and couldn't help being a little surprised.

"Are you guys so extravagant now? Brother Han is really generous. He bought three roast ducks at once. This must have cost at least ten yuan."

This roast duck is not cheap now, and it is far beyond the scope of reimbursable meal expenses. Han Weiguo can buy three of them with his own money, so it is not an exaggeration to say that he is generous.

But Han Weiguo laughed and said, "Haha, I didn't buy three, but twenty-three, one for each of our staff members."

After hearing this, Cao Xing was so shocked that his eyes almost popped out of his head. It felt like a big steamed bun was stuffed in his throat and he almost choked to death.

He opened his mouth wide, looked at Brother Han in astonishment, and stammered.

"Han...Brother Han, are you crazy? Are you not going to live the rest of your life? Don't forget that you haven't even found a wife yet! What special day is today that makes you spend so much money?"

A barely perceptible blush appeared on Han Weiguo's face, and he looked a little embarrassed, but he still spoke bravely.

"Brother, don't get excited. I didn't spend any money. Hey, this meal money... this meal money... this meal money will all be put into your account!"

"Wha...what?!"

When Cao Xing heard this, he was completely stunned.

It took him a long while to come back to his senses, and he felt that the fragrant and sliced ​​roast duck in his hand suddenly became tasteless.

If you eat this thing for free, it will of course be delicious, but once you have to pay for it yourself, the feeling is completely different, as if something is missing.

When Mr. Liu heard this conversation, his expression did not change at all and he remained calm and composed.

He just picked up the roast duck on the table as if nothing had happened, turned around and strode out of the room.

Han Weiguo also hurriedly followed, not even daring to look at Cao Xing's somewhat resentful eyes. Only Cao Xing with a wry smile on his face was left in the room.

Although he doesn't lack this little money, he is a patient and a hero who has just made a contribution. Is it too early for him to pay for his own meal now?

After going around for a long time, Mr. Liu didn't give me any benefits at all, and I even had to pay a lot.

But he was used to it, and with the system's rewards to comfort him, he could finally laugh.

The rewards from this system are not something from the technological world.

But it is a rare treasure from the fantasy world.

This is a sapling.

According to the system, this sapling is called Tianyuan Tree, and it is one of the rare treasures in the fantasy world.

The fruit of this tree is called Tianyuan Yannian Fruit. Eating one can cure all diseases, make you immune to all poisons, keep you young forever, and increase your life by 50 years!

Cao Xing cared about it very much and specially cleared a large area in the space to cultivate this Tianyuan tree alone.
