Interrogation room. There is no greenery inside, just bare walls. The tiles around are all in cold tones, but the air conditioning temperature is not low enough, making the room hot and uncomfortable.

The iron railing in front looks intimidating, and the police behind it are even more fearsome.

Before the iron fist of the authorities hit him, Wang Song thought he could endure it. But in reality, most people have proven that the iron fist is really heavy.

Wang Song used to travel abroad. It was a cooperation project between Jianyuan and other companies in Africa. The location of the project was desolate and restrictive, making it feel like being in prison.

The income was not high, with an annual net income of just over 200,000 yuan, but the benefits included food and accommodation, still feeling like being in prison.

Wang Song felt that it was better to sell big. But now, sitting in the police interrogation room, he felt terrible.

The oppressive feeling emanated from the interrogation room even before he was handcuffed. The air quality in the room was not bad, and Wang Song believed that no one had vomited, defecated, or even lost control outside the room.

The more frustrating emotion came from the demands of the interrogating police. Writing a paragraph ten times? That was a reward system that only college students would have.

But after careful consideration, under the stern gaze of the police, Wang Song silently copied it ten times.

Wang Song despised himself. At that moment, he felt like he was back in school, being bullied by other students, hating himself for not daring to resist.

But more than that, Wang Song was afraid. The interrogating police were definitely frightening, so what about the police outside the prison?

The inmates outside the prison, maybe they would be like the workers at the construction site, not saying a word or laughing... It took a lot of effort to copy a long paragraph ten times.

Before copying it ten times, Wang Song handed it to the police officer like a college student.

"Show it to the expert," the forensic officer said, then got up and walked out with the copied notebook.

In the interrogation room, there was also Wang Song, who was a part-time worker in Qinghe City, and an expert who came from Changyang City.

Since Yuan Yutang died, the case had been upgraded to a homicide. In the scope of Qinghe City, it was a high-profile case, regardless of whether Jianyuan Corporation was going public or not, the case was pressing.

At the same time, the resources that the forensic officer could mobilize had become scarce. Mainly because Jiang Yuan had been solving the case too slowly, so that Cheng An had time to allocate resources, and Bai Yuequn had given orders.

With the main suspect already arrested, the allocation of resources was exaggerated. Whether it was borrowing an expert from the Criminal Investigation Detachment of Changyang City, it was possible.

In addition to Jiang Yuan, there were eight Wang Songs, all spread out in a large room, each looking at a few sheets of paper and exchanging them with each other.

Jiang Yuan held a magnifying glass and carefully read the ten copies, then looked at the original text and the photos. Jiang Yuan not only looked at the Arabic numerals, but also focused on the word "WeChat" and the structure of some other words.

Yes, Wang Song could not use the original words for comparison, nor could he use other words for analogy. In theory, the simpler the word form, the less helpful it was for Wang Song's judgment.

The word form of "WeChat" was distinctive enough. Jiang Yuan basically confirmed after looking at a few sheets of paper that Lei Xin was the one with suspicious handwriting.

Since he was here, he also looked at the remaining versions. Lei Xin had not deliberately concealed the handwriting in any of the versions.

The original text was written with the right hand, and now it was all copied with the left hand, but it still looked very similar.

However, it was all useful. The first thing to look at was the similarity between the ten copies.

The handwriting of different people had very low similarity. For example, if a paragraph was copied ten times, they should all be basically the same.

The difference in the handwriting was minimal. Lei Xin had not undergone any special training, so when he copied it ten times, he used his usual writing style, and his performance was stable.

The small difference in the handwriting proved that he was hiding something. And the act of hiding something itself could explain the problem.

Next was the comparison between his handwriting and the physical evidence... In general, there were too few flaws, and it was difficult to find a good place to start.

The other two Wang Songs also had similar expressions. Before Lei Xin was exposed, Jiang Yuan's work was already very complicated. After the eight people confirmed, the forensic officer breathed a sigh of relief, thanked them, and confidently returned to the interrogation room.

In the interrogation room, Lei Xin, who had been sitting silently for a long time, had not yet figured out how to write "Your Struggle."

"Just tell us that your expert Wang Song has been confirmed, and that he wrote that note," the forensic officer presented the note. Cheng An swallowed and hesitated. Cheng An said:

"You are interested in him, you want his confession, to catch the people under him. But if he speaks, you have to catch him. It's a homicide case, you can't afford to be vague." Cheng An's eyes were still red, but he continued to speak.

"You know what conditions his superiors promised him, but ask him to think about it. At this point, does he think that I can fulfill my promise to him?" The forensic officer coaxed persuasively."You must have said something... is it considered... a performance, a meritorious deed?" Lei Xin spoke without much hesitation.

"It doesn't count." Wen Jian switched on her femme fatale mode, her smile already gone.

"How long are you planning to sentence him?" Lei Xin's gaze was intense as he stared at Wen Jian.

"That depends on the nature of the crime. He definitely said it, incitement is equivalent to complicity in the crime, premeditated murder, and it involves two people..." Wen Jian paused, then continued:

"If he properly reveals the mastermind and cooperates with your investigation, the sentence will be significantly reduced." Lei Xin took a deep breath, even leaning back slightly, and said emphatically:

"It's Seventh Master Yuan Yulang." After finishing that sentence, he paused for a moment, and my speech flowed more smoothly.

"I'll send you a picture, you tell me who sent this. Seventh Master said he didn't enjoy watching Old Eight just for fun, Old Eight talks too much trash, he wanted revenge, to embarrass me, maybe break a leg or something. Seventh Master said Old Eight's girlfriend is someone special, but unexpectedly..."

"What they were originally thinking, you guys can discuss that later. Tell me specifically what he did." Wen Jian maintained control over the rhythm of the interrogation, even as answers came forth, my face showed no sign of any change.
