Chapter 41 Test Results
"Testing tube? Epidemic prevention station?"
Wu Feilin muttered something to himself, then turned to look at Lao Zhou, "Was what Ah Huai said useful?"
"It is useful, but..." Old Zhou pondered for a moment, then tried to justify himself, "The testing tubes at the epidemic prevention station are specifically for factory contamination, not for solving cases, which is why I didn't think of them at first."
Wu Feilin did not continue listening to Lao Zhou's explanation.
Now that we know it's feasible, let's choose to do it.
"Monkey, immediately have the bureau contact the epidemic prevention station and ask them to help allocate a test tube."
"Understood, Master."
After Hou Hao responded, he immediately ran downstairs.
While waiting, everyone in the room sniffed, trying to detect the "sour" smell that Gu Huai had just mentioned.
However, since no one had specifically researched formaldehyde beforehand, even with preconceived notions, it was difficult for people to detect the faint sour smell no matter how hard they tried.
Ten minutes later, Hou Hao rushed upstairs.
"Master, the epidemic prevention station said they've already gone off duty. If we really need it, they can contact someone to go to the station, but that might take a lot of time."
"How long will it take?" Wu Feilin asked, frowning.
Two hours.
"Why is it taking so long?" Gu Huai interjected. "Where did they come from?"
"Futian." Hou Hao took a breath and explained, "The station chief said that everyone in the station is celebrating the Lunar New Year at home, and he's on duty alone at the epidemic prevention station. He needs to contact someone to relieve him before he can come here."
Gu Huai glanced at his watch; it was already 9:31.
According to Hou Hao, the head of the epidemic prevention station would arrive at the earliest at 11:30.
"No, there's no time," Gu Huai said. "Team Leader Wu, could you please contact the people at the epidemic prevention station and have them wait there? I'll drive over to pick it up."
Wu Feilin had no objection to this, nodded quickly, and then gestured towards Hou Hao with his lip, "Monkey, you go with Ah Huai, he's new here and probably doesn't know the way."
"Eh."
After going downstairs, Hou Hao walked straight to the head seat of the car. "Ah Huai, let me do it."
"I'll do it," Gu Huai insisted.
He had seen Hou Hao drive before; he wasn't terrible, but his driving skills were just passable, nowhere near as good as his own, a veteran driver with twenty years of experience.
Seeing Gu Huai's insistence, Hou Hao didn't say anything more and simply tossed the key to Gu Huai.
After getting into the car, Hou Hao took advantage of Gu Huai adjusting the seat to ask the question that had been on his mind.
"Ah Huai, there's something I don't understand. Even if we prove that Luo Zhenbang removed formaldehyde, it doesn't prove that he killed someone."
"We don't need to prove anything." Gu Huai turned the key and started the police car. "He's just a taxi driver, keeping so much formaldehyde at home. It's Luo Zhenbang himself who needs to prove it."
"He could easily make it up," Hou Hao said. "For example, he could say he was helping someone carry something, or that he found it. He could just make up any excuse and get away with it, right?"
"Then let him make it up," Gu Huai chuckled. "The more he makes up, the more flaws he'll reveal, and we can solve the case directly by seizing those flaws."
Under Gu Huai's control, the vehicle slowly drove out of Yunshu Village.
At first, because it was in a village and the roads were narrow, Gu Huai didn't drive very fast.
Once they were on the main road, Gu Huai turned on the police car siren and floored the accelerator.
Fortunately, Shenzhen in 93 was different from later years, and there weren't many vehicles on the road.
Gu Huai arrived at the epidemic prevention station in half an hour, traveling at an average speed of 80 km/h.
Hou Hao kept gripping the handle on the car. "Ah Huai, how long have you been learning to drive?"
"One month." Gu Huai stopped the car, got out, and walked towards the epidemic prevention station.
At this moment, Station Chief Wu of the epidemic prevention station was already standing at the door with a box, waiting.
Upon seeing Gu Huai, he remarked, "Wow, you guys got here pretty quickly."
"Time is of the essence," Gu Huai said without exchanging pleasantries with Station Master Wu. "Station Master, could you teach us how to use this?"
"The testing tubes and manual samplers are all inside. I've already explained how to use them to your technical team." Station Chief Wu didn't waste any words. He took out a booklet from his pocket and handed it to Gu Huai. "This is a color chart for formaldehyde content. After the inspection, you can use this color chart to determine the approximate formaldehyde content."
Gu Huai opened the box and took a look.
A dozen or so glass tubes were neatly arranged, filled with white silicone particles, just like those in a memory device.
"Thank you, stationmaster." Gu Huai nodded slightly and then turned to walk towards his car.
Watching Gu Huai's hurried figure, Station Chief Wu remarked, "Young people are so energetic, they get things done so efficiently."
Back in the car, Gu Huai started the police car again.
"Ah Huai, let me drive when we get back." Hou Hao was really frightened by what Gu Huai had just said. Someone who had only learned to drive for a month dared to speed on the road. No matter how you looked at it, it was a bit too daring.
"Don't worry, nothing will happen." After saying that, Gu Huai started the car without saying another word, stepped on the gas pedal hard, and the car shot off.
They traveled in silence until they returned to Yunshu Village at exactly 10:20.
Gu Huai ran all the way back to Luo Zhenbang's residence and handed the toolbox to Lao Zhou.
Old Zhou connected the testing tube to the manual sampler and took different air samples from three locations: the center of the room, a corner of the room, and inside the wardrobe.
The silica gel particles slowly change color inside the glass tube.
It started as white, then turned into light purple, and then into dark purple.
Old Zhou's expression also changed.
"How much?" Wu Feilin leaned closer.
Old Zhou checked the colors and said, "The formaldehyde content in the middle of the room is 0.8 milligrams per cubic meter, the corner near the bed is 1.2, and the highest is inside the wardrobe, at 1.5."
After saying that, he explained, "It's exceeded the standard! Normally, the indoor formaldehyde concentration should not exceed 0.08, this is seriously excessive!"
Gu Huai continued, "Judging from the concentration in Luo Zhenbang's room, it means he has stored a large amount of formalin here for a long time. The reason we didn't find it is because he secretly took it away before we came here."
Wu Feilin's expression gradually became serious. He looked at Lao Zhou and asked, "Is there any scientific basis for what Ah Huai is saying?"
"Yes, there are." Old Zhou nodded. "It's probably because the stopper on the bottle he used to store the formaldehyde wasn't very airtight, and the formaldehyde leaked out. Those bottles Ah Huai mentioned definitely exist!"
Wu Feilin stared at the testing tube for a long time, then suddenly said to Lao Zhou, "Lao Zhou, take the monkey and ask around the village to see if anyone has seen those bottles. I'll go back and interrogate Luo Zhenbang now."
After saying that, he walked outside.
As Wu Feilin reached the door, he suddenly stopped.
After a moment of contemplation, he turned his head with a complicated expression and said to Gu Huai, "Come back with me."
