Li Hui left.

Once he left, Chen Xiao couldn’t just leave Teacher Xiao alone.

Although Chen Xiao couldn’t find much to say about academic knowledge.

But as an audience for a retired old teacher, he could still qualify.

It was simple; while listening, he occasionally praised Teacher Xiao for his achievements in teaching excellent students worldwide.

Teacher Xiao spoke with glowing enthusiasm, especially when he mentioned those outstanding students he had taught, his eyes sparkling with pride.

Chen Xiao nodded from time to time.

He didn’t think Teacher Xiao was bragging; instead, he felt that this teacher truly deserved respect.

What can make a teacher prouder than training thousands of excellent students over several decades?

After chatting for an unknown amount of time, Li Hui finally returned.

“I’ve checked and notified everyone, and I called Cheng Qing’s parents again.”

“But both are honest farmers, so they still don’t know much about their child’s affairs at school.”

This is indeed a fact.

The parents from Cheng Qing’s era were even less educated than Chen Xiao’s generation.

Parents with little education supporting their children’s schooling was already a far-sighted endeavor.

As for school matters, it’s normal not to know.

“How long until the notified ones arrive?” Chen Xiao asked.

Li Hui replied, “Cheng Qing attended Songtan Town for three years in middle school, but the teachers were different each year. So I’ve found three in total, two homeroom teachers and a math teacher. Others are either out of town or have passed away.”

“The two homeroom teachers are enough.”

Chen Xiao said this, and Teacher Xiao, seeing this, said with visible fatigue, “Since you still have a case to handle, I won’t disturb you further.”

“Thanks for coming tonight, Teacher Xiao, traveling so far and late to assist.”

“Captain Li, you’re too polite.”

“I’ll escort you.”

Li Hui was very courteous to Teacher Xiao, and Chen Xiao could feel it since Teacher Xiao arrived at the detective team.

After escorting Teacher Xiao out, Chen Xiao couldn’t help but ask, “Did Captain Li also attend Chang Hua Middle School?”

“No, my grades couldn’t get me into Chang Hua back then.”

“I saw how respectfully you treated Teacher Xiao and assumed he was your mentor.”

Chen Xiao said, considering that Li Hui, as a detective team captain in Lanshan County, many would have to call him leader when meeting him.

But what Chen Xiao didn’t expect was Li Hui suddenly slapping his forehead in frustration.

“Ah… I didn’t realize until you mentioned it, I had something to discuss with Teacher Xiao before contacting him today. Who would’ve thought the case discussions made me forget?”

“What was it?”

“Teacher Xiao’s daughter is now a head at Chang Hua Middle School; my younger sister Xiaoxue recently transferred there too, and I wanted them to get acquainted.”

Chen Xiao realized and didn’t say much more.

Soon, an officer brought some files over, and upon seeing Li Hui, said, “Captain Li, here are the academic and household registration files you asked for.”

Chen Xiao couldn’t help but look at Li Hui.

At this moment, he felt an urge to commend Li Hui.

Li Hui is definitely someone who can handle overseeing the larger scope of work.

Even Chen Xiao had overlooked checking Cheng Qing’s academic and household information.

Why check the household information?

Chen Xiao had clearly stated earlier his suspicion that Cheng Qing’s achievements might have been impersonated when entering Chang Hua.

And the impersonator, in Chen Xiao’s suspicion, was Chen Xianzu!

Although this was just a baseless guess, Li Hui managed to cover everything thoroughly.

The documents he brought were not only Cheng Qing’s but also Chen Xianzu’s.

Although the latter had passed away years ago, it didn’t mean this person was untraceable in the records.

When he was born, when he died, which school he attended, and whether he changed his name can all be clearly investigated!

Chen Xiao and Li Hui started to review the files.

One looked at Chen Xianzu’s, and the other at Cheng Qing’s.

After looking through them, the two exchanged looks.

Li Hui: “When Mr. Chen mentioned that possibility earlier, I felt like a deep inner tranquility was fiercely disturbed, so looking at these documents makes me feel uneasy.”

Chen Xiao frowned slightly.

The comparison of their records showed almost no signs of impersonation.

The only common point was that both had repeated grades.

But the difference being, Cheng Qing was in third grade middle school, while Chen Xianzu was in elementary school.

Regarding Chen Xianzu repeating elementary school, Chen Xiao seemed to remember hearing about it.

Even though Chen Xianzu was much older than Chen Xiao, he didn’t know where he heard the title “Songshanping’s Repetition King.”

And this title referred to Chen Xianzu.

It was later, after seeing Chen Xianzu’s transformation, that elders jokingly remarked who would’ve thought the former repetition king would become Songshanping’s college student!

Looking at his school history, Chen Xianzu wasn’t exactly a repetition king initially.

He seemed just unable to get into learning at first, but once he did, he smoothly advanced like unlocking the Ren and Du Meridians.

However, though slightly older than Cheng Qing, Chen Xianzu eventually reached the same starting point in the third grade.

This starting point was merely the grade level they were in.

Both entered high school in the same year, but Cheng Qing went to the prestigious Chang Hua Middle School, while Chen Xianzu attended the somewhat lesser known Lanshan No. 3 Middle School.

Neither had any record of changing names.

The documents clearly showed that besides being from Songtan Town and entering high school in the same year, they shared no commonality.

After giving the documents another look, Chen Xiao decisively said, “I was wrong.”

Li Hui’s eyelid twitched, saying nothing as he scrutinized Chen Xiao.

Chen Xiao smiled: “Captain Li, no need to look at me like that. Although you’re the police and I’m an ordinary citizen, we’re doing the same thing. In what we’re doing, being wrong is wrong, and being right is right; there’s nothing we can’t admit.”

“Do you still want to personally question those teachers?” Li Hui asked.

Chen Xiao nodded: “Yes, of course. This only eliminates one of our inner suspicions. The skull was found in the stone lion at Chen Yuan’s house, and Chen Yuan had some odd transactions. These points make both Chen Yuan and the deceased Chen Xianzu suspects.”

Li Hui: “Indeed, this case has been unsolved for fifteen years, but we’ve uncovered many things in just a day or two, right?”

As they spoke, both Chen Xiao’s and Li Hui’s phones almost simultaneously rang.

They glanced at their phones, then at each other, and spoke in unison: “It’s news from the forensic side; the matching results must be out!”

As they spoke, a thought arose in both their minds simultaneously.

What they were doing now was taking one step and looking three steps ahead, constantly investigating.

So the matching result is crucial. If the skull is Cheng Qing’s, then Chen Xiao and Li Hui would feel a heavy burden lifted.

But what if it isn’t?
