After meeting Professor Xu, Su Heng understood that there was no point in pretending to be someone from the investigation team, so he simply revealed his true identity.

But this is also half-true, at least the subterfuge team is true, and the name is also true, but the subterfuge team is not subordinate to the Seventh Division of National Affairs, not now, and not before.

The reason why she pulled this tiger skin was also because of Tang Jiuge, her identity could withstand investigation.

Professor Xu's performance was surprising, and after hearing about the Mystery Team, he was only slightly surprised, and then calmed down, and her calm was really calm, the kind that didn't make waves in her heart, not a disguise.

"Captain Su Heng, hello, I've heard of your name for a long time, but I didn't expect to see each other one day."

And Professor Xu's words surprised everyone present, even Su Heng was stunned for a moment.

"Professor Xu, do you know me?" Su Heng couldn't help but ask.

"Yang Qing is my student, and I know some inside information about the incident three years ago because of some special reasons." Professor Xu explained.

"Since Professor Xu knows me, he should understand the purpose of my visit this time, right?"

Su Heng didn't expect it to be such a coincidence, as for Yang Qing in Professor Xu's mouth, he was one of the eight people killed in Case 136, leading the team.

Although the files were sealed after the almost total annihilation of the Crime Unit, it does not mean that no one knows about it.

In fact, many people's energy is beyond imagination.

Su Heng didn't care how the other party knew, on the contrary, this kind of knowledge was more beneficial to him.

"I know, if Captain Su doesn't mind, come to the study with me to talk." Professor Xu nodded, and then said to Tian Li beside him, "You help me take care of the guests." ”

"Mom, why don't I accompany you."

Tian Li obviously wanted to know all this, but under her mother's stern gaze, she finally had to take a step back.

Su Heng came to the study with Professor Xu, in fact, even if he didn't have this invitation, he wanted to come in and take a look, after all, one of the pictures he saw from Tian Lao's eyes was the old map in the study.

Seeing Su Heng looking at the map on the wall in a daze, Professor Xu didn't bother him, but waited for him to finish reading it before saying, "Lao Tian has been reading this map for most of his life. ”

"This is left by Tian Lao's father?" Su Heng asked.

"Sort of, my father-in-law did leave a map back then, but it was too damaged, Lao Tian copied this one according to that map, it can be said that the two are exactly the same." Professor Xu seemed to remember something, and his face became more and more gentle.

"Your father-in-law is amazing." Su Heng said sincerely.

On the map, there seem to be only six routes, but they almost run through most of China, especially through various remote places, without great perseverance, without years of arduous trekking, it is absolutely impossible to complete this task.

"Although I haven't met my father-in-law, he is indeed a great person." Professor Xu said slowly.

"Haven't you seen it? Don't know when your father-in-law died? Su Heng immediately asked.

"December 6, 1958." Professor Xu remembers it very well.

"December 6th? Three months after that photo was taken? So how did he die? Su Heng felt that the death of Tian Lao's father might be related to the statue.

"I don't know, it's said that he was crazy, and then he disappeared, but it's a pity that Lao Tian has been reluctant to tell it, and since then, he has been bent on tracking down the truth of the year, and the only clue is the photo left by his father-in-law, and a notebook." Professor Xu shook his head and said.

Su Heng didn't immediately ask about the notebook, the third picture he saw from Tian Lao's eyes before was the treasured notebook, but unfortunately he didn't open it at that time, so Su Heng didn't know what was written inside.

Unexpectedly, the notebook was left by Tian's father, but if you think about it carefully, it's normal.

"I'll give you the photos and notebooks later, but you need to promise me one thing." Professor Xu suddenly looked at Su Heng and said.

"You said, as long as I can do it, I will never shirk it." Su Heng was shocked and said.

"I want you to fulfill his last wish." Professor Xu's tone was noticeably heavier.

"Not revenge?" Su Heng obviously didn't expect Professor Xu to make such a request, which was a bit unexpected for him.

In his words, even if he dies suddenly one day, it is just retribution, no matter what the crime is, he goes down to redeem it, but the only thing he can't let go of is the matter of his father-in-law back then.

Now that Lao Tian is gone, the only thing I can do is to help him fulfill his last wish and find the truth about the murder of my father-in-law. Professor Xu said seriously.

"Professor Xu, don't worry, even if you don't say anything about this matter, I will do it, but I have a few questions for you." Su Heng nodded without hesitation.

"I want to know who Tian Lao contacted last night?" Su Heng thought of Tang Jiuge's words and asked directly.

"According to Lao Tian, it is an exploration team, after all, my father-in-law walked too many places back then, and even if there is a map, it is not easy to find possible locations." Professor Xu said.

"So how is Tian Lao's mood recently? Did you say anything? Su Heng continued to ask.

"Lao Tian's mood is good and bad, but recently, especially after the arrival of Xiao Gao and Xiao Tang, he seems a little excited, and even after the two left last night, Lao Tian couldn't sleep, and drank a glass of red wine alone."

Professor Xu struggled to recall.

"By the way, before going to bed last night, Lao Tian was still muttering something soon, soon."

"Soon?"

Su Heng's spirit was shocked, could this be the truth of his 'suicide'?

And what Tian Lao said is fast, the biggest possibility is that he is about to find the statue in the photo, or the truth of the year.

But no matter what point it is, it is also very important for Su Heng.

With Yan Li being killed, the other murderer was also completely hidden, and the only thing Su Heng could be sure of was that through the picture he saw in Yan Li's eyes, the other party had a kind of devotion to the statue that was almost worshipped.

If Su Heng wants to find him, then it is imperative to find a real statue again, or to find out the true identity, origin, and purpose of the statue.

It's also the only way to turn reactive into proactive.

You can't continue to let him open a bar and wait for the other party to kill, right? What if the other party disappears and hides completely?

After all, he has been waiting for three years, and it is impossible to wait another three years.

Half an hour later, Su Heng left with his things.

Closing the door, Professor Xu seemed to have unloaded his last breath, his body staggered, and he almost fell.
