The director of the Civil Air Defense Office couldn't explain it even after he was questioned hard.

He ran back and forth, urging the cryptographers to find a solution.

Seeing that there was a deadlock when opening the door, Xu Yishan, director of the People's Defense Office, invited the cryptography expert over.

"Comrade expert, can't you decipher the code?" Xu Yishan asked tentatively.

The expert explained awkwardly, "Leader, it's not impossible to decipher, it may take some time. We just studied it and found that the password for this door is not an ordinary password design, but uses the SHA-1 password program."

Xu Yishan said oh, he didn't know what the "sha-1" password program was.

The expert continued to explain: "For example, computer deciphering methods are used to decipher passwords now. Usually, it will not take more than three minutes to decipher a password. But if the password uses the SHA-1 program, even if a supercomputer is used to decipher the password, it will not take more than three minutes.

Calculation may take a million years."

Fei Jin said in surprise: "A million years? Are you kidding?"

The expert said solemnly: "Yes, super computers will also take a hundred years."

He sighed and said, "So, there's nothing you can do about it?"

The cryptography expert smiled bitterly and said: "Aren't we making various attempts? But it will definitely take time."

Fei Jin sneered: "So, we have to wait a million years?"

After listening to the cryptography expert's explanation, everyone felt like a deflated ball.

Fei Jin suddenly said: "Zhou Wenwu should know the password of this door."

The director of the Civil Air Defense Office said: "Since Zhou Wenwu is in your hands, do you still need to go to all this trouble to ask him to reveal the password?"

Fei Li smiled bitterly and said: "Who said Zhou Wenwu is in our hands? Besides, that kid has already eaten the weight, knowing that he is dead. So this kid has been unwilling to cooperate with us in handling the case. Even if that kid is in our hands

, it may also be a big difficulty for him to come up with the password."

The director of the Civil Air Defense Office said with a smile: "You policemen still have some means. I guess if the Bodhisattva falls into your hands, he won't even dare to recite sutras."

Fei Jin snorted coldly, "You guys are all looking at people through colored glasses. What do you think our public security agencies are like?"

Between the two of them, you say something and I say something, and no one gives in to the other.

The cryptography expert sighed and said: "Both leaders, don't argue. Let me explain. The SHA-1 password was designed and released by a relevant government agency of a certain country based on the hash function. It is known as the most difficult password to crack in the world. We

There is a country's cryptography expert named Wang Xiaoyun who has deciphered it, but we don't have her deciphering code. So, we don't have to wait a million years. As long as we can get expert Wang's deciphering code, we can do it in a few minutes."

Fei Jin said angrily: "Where can we find this expert named Wang Xiaoyun?"

The scene fell silent. Faced with the most difficult code in the world to decipher, the cryptographers were at a loss what to do.

Xu Yishan smiled lightly at this time and said: "Don't be anxious, everyone. There will always be a way. So, comrade experts, can the two of us communicate alone?"

The expert quickly said: "Of course."

Xu Yishan's words were actually not meant for cryptography experts. They were meant for Fei Jin and the director of the Civil Air Defense Office.

Sure enough, both Fei Jin and the director of the Civil Air Defense Office heard the meaning of his words. Fei Jin took the initiative and said: "Let's step aside and ask Director Xu to communicate with the experts."

Xu Yishan asked the cryptography expert to bring a piece of paper. He wrote the password he got from Zhou Wenwu on the paper, handed it to the cryptography expert and said, "Try to see if you can open it with this."

The cryptography expert was hesitant. He hesitated for a moment and then returned to the basement door with the password.

After entering the password, only a slight "chirp" sound was heard, and the basement door slowly moved aside.

Everyone was stunned. For a long time, there was no sound from the scene.

Xu Yishan's tense heart dropped to the ground. He thought to himself, it seems that this boy Zhou Wenwu didn't lie to him.

Fei Jin and the director of the Civil Air Defense Office could hardly believe their eyes. Even cryptography experts were at a loss to open the door. How did Xu Yishan know the password?

Due to a long-term power outage in the basement, the power supply for emergency lighting was also exhausted. Therefore, the basement was completely dark and it was impossible to see anything inside.

I ran to the basement door with great effort, looked inside, and then hurried back to Xu Yishan and said sincerely: "Director Xu, you are impressive."

There are two meanings in this sentence. No matter how Xu Yishan knew the password, it is no longer important. His ability to open the basement door surpassed everyone present, including cryptography experts.

Another meaning is that Xu Yishan has completely conquered him.

The team that opened the basement door was well prepared. Soon, the power cord was connected.

The moment the lights came on, everyone was shocked. The basement, which everyone cared about, was actually empty.

"There's not even a hair on it," he said dejectedly.

On the contrary, the director of the Civil Air Defense Office became proud, "This is a civil air defense project. We have strict requirements and cannot pile up any items to avoid problems during emergency evacuation."

Xu Yishan couldn't believe that what he saw before him was real. Why was there nothing in the basement?

If the basement is just an empty warehouse, Zhou Wenwu is full of food, so he has to go to great lengths to create a "sha-1" password to make things mysterious?

If there is a secret hidden in the basement, where is the secret?

The basement was spotless, and the floor was so bright that people's shadows could be reflected on it.

Everyone was looking around at the basement door, with disappointment written all over their faces.

It's so surprising that this basement, which cares about everyone's hearts, would show such an appearance.

But looking around the basement, there is no damage anywhere. This means that no one has entered the basement before the basement door was opened.

If it is said that the basement has been tampered with before, this possibility is almost non-existent. First of all, from the discovery of the basement to the present, the basement has been in full view of the public, with more than a dozen pairs of eyes staring at the basement door every day.

Even a fly flying by will leave traces.

He scratched his head hard and said, "Hey, what's going on? Is it empty?"

The director of the Civil Air Defense Office smiled and said: "It was originally empty. It was because of your complicated thinking that you thought there was a treasure hidden in it. Now, are you disappointed?"

The empty space in the civil air defense project shows that the civil air defense office has done a good job. The scene in front of him made the director of the civil air defense office extremely happy.

Xu Yishan couldn't believe what he saw. He pondered for a while and said: "Don't panic, everyone, Director Fei, let's go in and check."

He comforted others not to panic, but actually he panicked first. However, no one felt his panic.

This basement once placed a lot of hopes on him.

From the moment he discovered the basement, he firmly believed that there must be a fatal secret hidden in the basement.

He has never denied his truest thoughts. It has always been the result of his efforts to capture Wei Li, Secretary of the Political and Legal Committee of Hengyue City. After Zhou Wenwu was brought to justice, he thought he could get useful evidence from Zhou Wenwu.

.But in all the materials Zhou Wenwu handed over, not even the shadow of Wei Li could be seen.

He knew the truest thoughts in Zhou Wenwu's heart. Zhou Wenwu initially thought that if he was caught, as long as he did not explain who was behind the protective umbrella, people outside would find ways to rescue him.

As the gaffe progressed, Zhou Wenwu already knew that he had no way out and only one way of no return. After that, he placed his wish on his family not to be implicated. He knew that as long as he revealed who his protective umbrella was,

, his family members left outside will definitely not have a good life.

When hope was dashed again, Zhou Wenwu's last hope lay in Xu Yishan. This was also the reason why he told Xu Yishan the password to the basement. He had a condition with Xu Yishan, that is, Xu Yishan must protect his family left outside.

Zhou Wenwu didn't want to personally explain who was behind the protection, because he had scruples.

He hoped that Xu Yishan could find what he wanted from the basement, which at least showed that it was not him, Zhou Wenwu, who betrayed the umbrella.
