Duan Xu finally got to know the two people who wore peaked caps and entered Xia's house through his own way.

Through the backs of the two people and some blurred faces, and then through some high-tech means, Duan Xu's team finally simulated a very clear real face.

After that, Duan Xu's team also went through some technical means to determine the summer social circles, and then took out the photos of all the people in these social circles for comparison.

Honestly, it's a pretty stupid approach.

Perhaps only a person like Duan Xu can find so many resources, so as to find some clues from here.

In other words, there are no high-tech equipment, and even many of the investigations involved in this are too many things, and not anyone can see them if they want to.

So when doing some things like this again, a person's identity advantage is well expressed.

Through restoration and comparison, Duan Xu determined the identities of those two people.

The identities of these two people are not very special compared to Summer, and these two people have not had much intersection with Summer for many years.

If it weren't for Duan Xu's investigation of the summer accident, he especially emphasized the need to check the nobles in the summer, from the fact that he had not yet developed to all the nobles after his development, none of them could be let go.

One of these two people, no one would have thought of it at all.

Because this person is just a very ordinary small businessman, a small businessman of this level is not worth mentioning in the eyes of the summer.

But it was a strange thing that he was able to go into his summer home.

By investigating the reality, one of these two people was a noble person before the summer was born.

This person's surname is Chen, and his name is Santang.

This Chen Santang is more than ten years older than Summer.

When the summer was not yet developed, Chen Santang once funded it.

Later, after making a fortune in the summer, he also wanted to feed Chen Santang, but Chen Santang refused.

Later, as the disparity between the identities of the two became wider and wider, the intersection became less and less.

Summer has summer ideals, and Chen Santang has Chen Santang's own life.

No matter how good friendships are, they don't often connect, or after the intersection of life becomes less and less.

Slowly, it faded a lot.

Duan Xu was able to find out about this past incident in the summer, but it was actually very difficult.

At least Xia Yue didn't know that there was such a person as Chen Santang.

In his father's friend list, Xia Yue knows that everything is either rich or expensive.

Even if Chen Santang survives until now, he can only be said to be a small businessman who is slightly better than ordinary people.

After so many years, his starting point is much higher than the summer, but he has not gone through the years, and his life has not particularly taken off.

But his life is not bad.

Ordinary people don't follow the rhythm of society over time, even if the overall social level improves.

He just said that he had changed from an ordinary person when he was young to an ordinary person when he was old, and nothing else had changed.

When society is developing as a whole. A person has not developed by a great leap forward, he is still just an ordinary person, if he does not develop, or even stops, then he will fall behind.

Obviously, Chen Santang is just an ordinary person who is developing with the rhythm of society.

Through Duan Xu's inference and investigation.

He found that Summer was not a person who did not miss the old. Don't look at the difference in his later development.

But as long as some friends came to him before he made a fortune.

He will be very generous to help them.

There used to be a friend who was not successful in the summer, because someone in the family was seriously ill and urgently needed money.

Summer was also directly generous, lending the person a large sum of money.

In the end, it was that money, and outsiders don't know if it was recovered in the summer.

So if one of those two people is Chen Santang, this is also very easy to explain.

A person who has not yet made a career in the summer, because he has funded the summer but has never asked for benefits from the summer.

The friendship between them should be extraordinary.

So if Chen Santang wants to see Summer, Summer will let him come to his house.

It all makes sense.

But a new problem arises.

Chen Santang and Xia have not crossed paths for so many years. So why did they meet at such a moment?

Is it just a simple reminiscence?

There was another person. Who is the other person?

Duan Xu didn't know.

Because I compare all the photos of my friends in the summer.

Compared with the other person in the photo, there is no person with a high degree of similarity.

So that person is also a mystery.

Of course, whether Chen Santang in the photo is really Chen Santang is not easy to say.

The assistance of high technology is only for corroboration and inference, and cannot be completely certain.

The restored photographs are just similar to the existing Chen Santang.

Without conclusive evidence, it's hard to draw conclusions about all this.

Therefore, Duan Xu's top priority is to find Chen Santang and then negotiate with him.

So as to determine whether this is true or not.

Duan Xu investigated Chen Santang's family again.

Chen Santang has only one son.

His son is also just an ordinary office worker.

His son also gave him grandsons.

The grandson is 10 years old.

However, his son and daughter-in-law divorced for unknown reasons last year.

This information doesn't seem to have much effect on the case as a whole.

Then Duan Xu was ready to talk to Chen Santang in person.

It's actually not that difficult to find Chen Santang.

Chen Santang was also busy in the capital when he was young, and later returned to his hometown of River Province and bought a house in the provincial capital.

Now he is also taking care of the children with his wife in the provincial capital and helping his son.

Duan Xu found Chen Santang's home.

However, what made him feel a little surprised was that he arrived at Chen Santang's house.

found that Chen Santang had died of a sudden illness three days later.

Three days ago, that is, when he almost found the line.

Chen Santang had an unexpected sudden cerebral hemorrhage and died before he had time to go to the hospital.

Duan Xu chatted with Chen Santang's son and also learned that Chen Santang had indeed been to the capital once.

said that it was for his grandson's illness to go to the capital to find acquaintances.

As for what acquaintances he was looking for, he didn't tell himself.

Duan Xu also learned that Chen Santang's cerebral hemorrhage also died suddenly when he was out shopping for vegetables.

Duan Xu didn't see from Chen Santang's son's eyes that he was hiding anything.

However, after Chen Santang went to the capital this time, he brought some special medicine back for his grandson.

According to Chen Santang's son, this game was indeed very effective for his son's illness.

Duan Xu took a special medicine from Chen Santang's son.

Because there was no packaging when the medicine was brought in.

However, Chen Santang was very firm and said that there was nothing wrong with this medicine.

Chen Santang's son couldn't stand Chen Santang's insistence, and finally had to give this medicine to his son.

Slowly, he found that there was no problem with this medicine, and his son's illness was getting better and better, so he was completely relieved.

During this period, he also asked Chen Santang how to get this medicine.

Chen Santang always said that his friend entrusted him with a relationship, but as for what kind of friend he was, Chen Santang kept silent.
