"Gaps in the bath?" Liang Zichen looked at Wang Shen in surprise.

"Yes." Wang Shen nodded. "If you look at the layout of this bathroom, it can be said that it is very simple, except for a shower, there is not even a shelf. In such a small space, there is no way to fit clothes. So I guess that when Ah Cheng was taking a bath, his clothes should have been placed on the bench outside the door. Wang Shen pointed to the bench not far behind him.

"Team Wang, do you mean that the murderer knew about Ah Cheng's habit, so he secretly changed his key while Ah Cheng was taking a bath, and then moved the order of the cabinet, so that Ah Cheng would naturally use the clothes in cabinet No. 17 after he came out of the shower?" Liang Zichen nodded as he spoke, agreeing with such a speculation.

"That's kind of how it went."

"Team Wang, no, there is another very important question here. Do you remember that day when Ah Cheng actually passed by us when he delivered food? Liang Zichen suddenly frowned again, thinking of the unexplainable question.

"Of course, we still smell gasoline. We thought it was a little strange at the time, and then the accident happened. Wang Shen walked out of the bathroom and sat on a bench answering Liang Zichen's question.

"Yes, the problem is with gasoline. According to the test results of our bureau, Ah Cheng's gloves were replaced with flammable cotton gloves. And petrol was poured on gloves and clothes. Gasoline is indeed an extremely flammable substance, but it has the disadvantage that it smells too much. Ah Cheng, it's impossible for a normal person not to smell gasoline, right? If you smell gasoline, don't you even have a little vigilance? Liang Zichen said one of the most important problems in the spontaneous combustion link.

"Originally, I didn't understand this question. But after meeting the attending doctor Wu Yi, the answer to the question became clear. After speaking, Wang Shen touched his pocket, took out a folded piece of paper from his pocket, and sent it to Liang Zichen's hand. Look at this. Wang Shen said to Liang Zichen.

Liang Zichen looked at the paper in his hand, slowly unfolded the paper, and then looked at it for a while. "This is a hospital visit record? Ah Cheng's? After reading it, Liang Zichen looked up at Wang Shen and asked.

"Yes, this was given to me by Wu Yi yesterday. When he checked Ah Cheng's medical records, he found that Ah Cheng happened to go to his hospital two days ago, and the cause was a severe cold. I also asked Wu Yi about the symptoms of a severe cold. A severe cold may have greatly reduced Ah Cheng's sense of smell. In addition, the gasoline on the clothes was not newly spilled, and the original smell was no longer so strong, and with the decline of Ah Cheng's sense of smell, everything became possible. After Wang Shen explained the reason, Liang Zichen's face showed an expression of sudden realization.

"This murderer is really powerful, and he uses it handily at the right time and place. Team Wang, if you hadn't happened to be at the scene at the beginning, I guess this case would have ended up with an accident. The expression on Liang Zichen's face became a little complicated, both a little surprised by the murderer's tricks and a little glad that he was at the scene.

"Therefore, the final problem is to lock down the murderer as soon as possible according to the clues, and return Ah Cheng to justice." After a short period of distraction, Liang Zichen said with a frown.

"That's right, but now we have to figure out what kind of entanglement there is between the murderer and Ah Cheng, so that the murderer will take the risk to take Ah Cheng's life." Wang Shen tapped the back of his head and said. "Also, we can't afford to make emotional mistakes, which could lead us into mistakes."

"What is an emotional misunderstanding?" Liang Zichen glanced at Wang Shen suspiciously.

"So far, we don't seem to have a good impression of Han Lin. However, after all, there was no direct clue pointing to Han Lin. So we can doubt everything, but we can't make judgments. Next, we're going to ......"

Before Wang Shen finished speaking, he heard an angry roar coming from outside the locker room. The roar was followed by hurried footsteps that hurried in the direction of the locker room. Not long after, Han Lin appeared at the door of the locker room, but with a little smile on his face.

"Ouch, Officer Wang, why don't you say a word here, it's really not well taken care of." Han Lin had a smile on his face, and as soon as he came in, he shook hands with Wang Shen familiarly.

"Manager Han is so polite, we just wanted to come and see this locker room on a whim." Wang Shen smiled and responded to Han Lin. Liang Zichen's movements were fast, he relocked the door of cabinet 16 before Han Lin entered the locker room, and took Ah Cheng's wallet.

"Then Officer Wang still needs any help? I'd love to help you. Han Lin smiled more earnestly, and said with a smile on his face.

"Can this cabinet 16 be opened for us to see?" Wang Shen smiled while looking at Han Lin and deliberately pleaded.

Hearing Wang Shen's question, Han Lin glanced at cabinet No. 16 and responded with a smile, "Ouch, Officer Wang, you're stumped on me." As I told you last time, there is only one key to each cabinet, and it is placed next to the owner of the cabinet. I don't have the key to this cabinet, so it should still be on Ah Cheng. ”

Wang Shen deliberately patted his head, "Manager Han, look at my brain, I'm really confused, why have I been forgetting things lately." After speaking, Wang Shen laughed twice.

"Officer Wang must have been too tired lately." Han Lin smiled and said in response.

"Okay, we know you're also busy these days, so we won't bother you with work." After speaking, Wang Shen shook hands with Han Lin, turned around and left the "Spicy Restaurant".

"Did Ah Cheng take his wallet?" After sitting in his car, Wang Shen looked at Liang Zichen and asked.

"Take it." Liang Zichen nodded. "Should I take it?" Liang Zichen continued to ask.

"You can take it. The killer must have had a spare key to the No. 17 cylinder. If the murderer found that a wallet was missing from the cabinet when he checked cabinet 16, he must have known that we had taken it. Perhaps, the murderer will panic. When people panic, they will do something unplanned. In this way, we have a chance. Wang Shen smiled and started the car.

"You mean the killer has a spare key?"

"Of course, the killer's chain core has been replaced, will there still be a key missing? And the original key No. 16 is in the murderer's hand, and the murderer will definitely see what Ah Cheng has hidden in the cabinet. Wang Shen replied solemnly.

"So the murderer of the wallet thought it was useless, so he left it in the cabinet?" Liang Zichen suddenly understood the meaning of Wang Shen's words.

"That's right, that means Ah Cheng may have left some important clues. But these clues have been taken or destroyed by the murderer. As for the mailbox behind the photo, it should have been kept because the murderer didn't pay attention. Wang Shen pursed his lips, his expression still serious.
