At this time, Stella woke up when she heard movement downstairs.

She immediately went downstairs to the room where the sound was sourced.

"You're all back?"

Stella said excitedly, holding her right hand over her chest and breathing a sigh of relief.

"Well, there's no danger."

Jiang Bai said lightly: "But I also found a lot of useful things. ”

"Something useful?"

Stella looked at Jiang Bai with some expectation.

"Not so sure, but my gut tells me it might work."

Jiang Bai continued to explain, "Because it's also something similar to the sign in the room. ”

"Sister Stella, we haven't slept yet."

Yan Xiyue said: "Even if I go to research now, I don't have much energy. ”

"Also, everyone have a good rest, and then study when you are in good spirits."

Stella nodded, yawning.

Because she was worried about Jiang Bai and them, she didn't sleep well all night.

By the time they all returned to their rooms, they had washed up and were ready to go to bed, the sun was already out.

However, the curtains of the villa have very good light insulation.

Close the curtains, just like at night.

They thought they had slept at night.

After a morning rest, Jiang Bai woke up at about two o'clock in the afternoon.

I know in my heart that if I go to sleep again, I will be better at night, but it will be a vicious circle.

He's not nocturnal, he can't be.

At this time, he opened the curtains and picked up the document bag that Liu Zifeng gave him.

The first thing to look at is Shi Xinxin's information.

Team Liu is right, she is not simple.

Shi Xinxin used to be a professor and senior researcher at a university.

Responsible for researching various histories.

Especially the history of the customs agencies and ciphers of various countries, no one in China can match it!

The reasoning ability is not even inferior to that of a professional criminal police officer.

Therefore, in the early days of personal information, there are often records of her helping the criminal police team solve the case.

However, the subsequent information was blank, and it seemed that someone had deliberately erased it.

This is the information brought from the criminal police team, and it stands to reason that it is impossible not to be complete.

It is also impossible for any hacker organization to attack and modify the information of the criminal police team.

Therefore, there is only one possibility, and the authority that Team Liu said is not enough - she is involved in some confidential matters.

Opening another file bag, Jiang Bai seemed to understand a little.

Shi Xinxin's husband's name is Zhang Zhuming, and he is a scientist.

Scientists who are truly at the forefront of scientific research!

When he was in high school, he was already studying the difference between bioelectric signals and computer electrical signals, a kind of research that Jiang Bai didn't understand at all.

Later, he was sent to a prestigious university, and finally entered a national electronic information research institute that has been made public.

There was a blank space in the following information.

Jiang Bai speculated that he should have been transferred to a research institute that could not be disclosed.

From the comparison of time and school, they are the same university.

I should have had a photo taken when I was in college.

Later, they co-participated in a study.

After the blank page, Shi Xinxin is "retired" and becomes an honorary professor.

On the other hand, it is a record of Zhang Zhuming's death four years ago due to an accident in some scientific experiments.

This corresponds to what Chen's mother said, "Since the master is gone".

But there was no cause or process of Zhang Zhuming's death.

It's even a simple vague statement of "killed because of a scientific experiment accident"!

Maybe it's really the lack of authority that Team Liu said.

Through the understanding of Shi Xinxin and her husband Zhang Zhuming.

Jiang Bai felt that this villa and the secret room could make sense.

But why did Shi Xinxin leave such a trace? Is she afraid that others will find her, or are you afraid that others will not find her?

Thinking like this, Jiang Bai thought about Chen's mother.

Chen's mother said that she didn't know about the secret room, and Jiang Bai had three speculations.

First, Chen's mother was ordered by Shi Xinxin to keep this secret.

Second, Chen's mother knew something and deliberately concealed it.

Third, she herself was deceived by Shi Xinxin, and she really didn't know.

In any case, Jiang Bai must ask her clearly in the process of cracking the password.

After reading these documents, the feeling of "clouds and mist" that he had just woken up from disappeared, and Jiang Bai began to look at the letters and think.

First of all, follow the upper left corner of the Tian character to cut out these words little by little.

He flipped through the pages and came to the last page of photos.

The slate.

He took pictures correctly at that time, and the traces on the slate just made him feel something.

He flipped through the photographs back and forth, comparing the letters with the hints on the slate.

According to the explanation on the slate, the Tian glyph below the red line does not need to be considered, only the upper half of the character needs to be cracked.

He didn't know if it was the right thing to do.

As Du Yiheng said, the password with multiple encryption must be difficult for people to understand before it is completely unlocked.

Even it still looks like gibberish.

On the other side, Li Qiming had already invited the "cattle man" to his home.

This person is Gao Zhiwei, who used to study history and ciphers under Shi Xinxin

"Hahahaha, if you tell me the shape of Tianzi, I can only tell you that I can't solve it."

Gao Zhiwei said with a smile: "Reporter Li, don't think about this. ”

"Why? I heard that you have been researching under Professor Shi before, how could you not know? ”

Li Qiming asked a little puzzled: "It stands to reason that you should be very clear!" ”

He thought that the "secret master" he invited would be able to kill Jiang Bai, but he was told such inexplicable words.

"You also know the direction and hobbies of Professor Shi's research."

Gao Zhiwei explained: "Even if I am promoted to professor now, I will not be able to reach it. ”

"That'...... No one can solve it? ”

Li Qiming asked, showing a hint of suspicion, and a little happy in his heart.

If even such a powerful boss can't be cracked, then Jiang Bai and a college student will definitely not be able to solve it!

"Yes."

Gao Zhiwei said: "Someone has indeed cracked the code. ”

"Who is it?"

Li Qiming couldn't wait to ask, "Can I get in touch?" ”

If someone can crack it, even if they pull down their faces and use all their connections, they will find him!

"The way to reach him should be simple."

Gao Zhiwei said with some jokingness: "Just find a rope and hang yourself." ”

Li Qiming frowned, "He's dead?" ”

"As far as I know, the only person who was able to crack Professor Shi's code is dead."

Gao Zhiwei said slowly, "Zhang Zhuming." ”

"This ......"

Li Qiming had a look of disbelief on his face.

"At that time, I was researching with Professor Shi, and she and Professor Zhang were very close."

Gao Zhiwei explained: "Professor Shi gave Professor Zhang a set of multi-encryption passwords, the first of which is the Tianzi shape. It's her favorite technique. ”

Under his explanation, Li Qiming gradually understood this unknown past.
