At noon.

Dingdong!

The doorbell was ringed, and a meal delivery employee riding an electric bicycle brought a sumptuous lunch to Zhao Yu and Cui Lizhu.

Lunches are customized from the guild hall, with Chinese and Western dishes, delicious and nutritious.

Although the meal and tips cost more than 1,000 yuan in total, the two of them ate very comfortably and felt that they were worth the money.

"Oh!" Cui Lizhu burped and exclaimed sincerely, "It's really beautiful to be a rich man. I wish we could find the treasure!"

"Now it's not just a treasure!" Zhao Yu was not as excited as Cui Lizhu. After eating in a hurry, he found a few huge pieces of white paper, placed it flat on the table, and began to write the investigation records.

This is a habit he has developed for a long time. He feels that only by writing the information himself can more ideas come out of his mind.

There are 16 names of people appearing on Tao Xiang's list, and there is a line of small characters under each name, marking the simple introduction of that person.

The 11 people in front were all marked "X" by Tao Xiang, but the five people in the last one were not. Zhang Jingfeng has confirmed that all five people died of heart disease.

Zhao Yu believes that the death of these five people should not be an accident.

Cui Lizhu understood Zhao Yu's habits and kept silently helping Zhao Yu.

Unexpectedly, when Zhao Yu had just written a lot, Zhang Jingfeng called again.

"Xiao Zhao, why are there so many names? What big case are you investigating?" Zhang Jingfeng seemed very puzzled on the phone, "It seems that these people have nothing to do with them!"

"Old Zhang!" Zhao Yu was eager to know the answer and hurriedly urged, "Hurry up, are there any problems with those 11 people?"

"Well... this is not easy to say! That's right, um..." Zhang Jingfeng's answer seemed a little hesitant, "The 11 people you asked me to investigate are no longer alive! It means there are 16 people in total, and there is no one alive!"

"ah!?"

The two were inevitably surprised.

"All... are dead?" Choi Lizhu changed her tone tremblingly, "Here... so many people, who did this?"

"Don't say that..." Zhang Jingfeng changed his mind and said quickly, "Although he is dead, the situation of these 11 people is a bit complicated, and it is a bit different from the previous five!

"Well... how do you say it! Judging from my information, these people died in a very long period of time. The earliest one can be traced back to 15 years ago, and the latest one was in the second half of last year. They are all scholars, and they have never done anything to commit crimes and have no evidence."

"Also, these people are of varying age, but most of them are already older, even those who are 90 years old! Moreover, according to the information, they all die normally, and it seems that they have nothing to do with heart disease.

"However, some people have too old age, and it will take some time to confirm them one by one!"

"That's it..." Zhao Yu smacked his lips secretly and said seriously, "Old Zhang, please help me investigate the detailed information of these people for the time being. All 16 people are required! I'll apply to the above. If possible, I will find a way to transfer you!"

"Okay! Look, okay!" Zhang Jingfeng hung up the phone happily and quickly sent the information he found to Zhao Yu.

"Boss...you have to think clearly!" Cui Lizhu reminded, "Do you really need to report this matter? Are we a little abrupt? Why don't we check it carefully before talking about it! What if those people die normally?"

Zhao Yu did not answer Cui Lizhu's question, but picked up his mobile phone, read all the detailed information of those people carefully, and then began to write on the white paper.

The entire writing process lasted for nearly an hour. Zhao Yu finally put away his pen and shook his head and said, "This white paper is not as good as a white board. If you write it wrong, you can't wipe it!"

"Boss, boss, how about it?" Cui Lizhu saw Zhao Yu talking and hurriedly asked, "Do you have any eyebrows? Who is the murderer?"

"I'll go!" Zhao Yu frowned, "I'm a detective, not a god. If I can find the murderer by just writing it casually, then I won't do anything else!"

"..." Cui Lizhu was speechless.

"Look..." Zhao Yu pointed to the already written materials, "Let's put death aside for the time being, let's take a look at these people first. Look..." He pointed to one of the names, "This person is a doctoral supervisor who studies modern history; then look at this one, an economist; this is a technical expert from the Cultural Relics Bureau, and there are some people who are engaged in scientific research projects, and even those who are engaged in exploration! How about it, what can you think of?"

"Well... these people are all knowledgeable and have high academic qualifications!" Cui Lizhu speculated, "and the majors they studied seem to be related to that batch of golden treasures! This..."

"Yes, there is a future!" Zhao Yu nodded, "I guess the reason why Tao Xiang wrote these people in the notebook is that these people have participated in actions related to finding treasures. Tao Xiang wants to find more clues about treasures through them!"

"So, every time he investigates one person and finds that they have nothing to do with the treasure, he will give him an X!" Cui Lizhu continued, "and he hasn't had time to investigate the five people behind?"

"It seems..." Zhao Yu said thinking, "It's not that I didn't have time to check, but, although I checked it, I didn't make sure it was done? Don't forget that Tao Xiang's box was buried under the floor! The floor was rebuilt by him, which means that he at least didn't plan to retrieve the box in a short time, right?"

"Oh..." Cui Lizhu looked at Zhao Yu in surprise, "It's worthy of being a big detective! When you say this, I suddenly realized. The reason why my dad didn't draw X for these 5 people is because these 5 people do know some news about the treasure, right?"

"Look at it again," Zhao Yu pointed to the name of the person in front and said, "Although the 11 people who drew X died, they were already very old when they died. Look... they are all over 70, 80 or even 90! Even a few younger ones died of terminal illnesses, not heart disease!

"Then what!" Zhao Yu pointed to the name of the person behind, "Look at the five people behind, although they are not young, they are not old enough to die. In this year's era, people in their 60s are not really old at all!"

"Oh..." Cui Lizhu nodded, "I understand. What you mean is that not everyone is really likely to die of a life-threatening death, but only these 5 people who have not drawn X!?"

"Absolutely!" Zhao Yuyan said, "The next thing is the most critical issue. Do you think that if these five people really die, then why would the murderer kill them?"

"My God!" Cui Lizhu said in surprise, "Because these five people know the secret of the treasure? Then... the murderer killed them. Do you want to know this secret or... want to kill someone to silence them!?"
