Chapter 412

The room where Yuan Shan once lived was decorated as before, including sofa, TV and tea table. On the tea table, there are still some fruits, but because they have been for some days and dare not replace them, they have begun to deteriorate.

The room was exquisite and clean. There was almost nothing special at the scene except Yuan Shan's two leather shoes under the sofa.

Now there is no fighting scene, let alone bloodstain. As for the glass, it is as clean as before, not even a handprint.

Not many people entered the room, including Xiao Yan, Qin Nan, Peng Dahai, and Qin Nan's two soldiers. One of the two soldiers used to be a scout, and the other was responsible for tracking and reconnaissance.

After entering the house, the conductor wanted to introduce Xiao Yan, but it was clear in the room that there was no need for any introduction at all.

Xiao Yan looked up at the top of his head and saw a ventilated place. He asked, "can you open this vent?"

"Yes, but it's very narrow, and people can't get in." because there is an access hole here, there is no need to make the ventilation pipe, so people can get in.

And the carriage can't be so high. In that case, the resistance of the motor car is too large to run at all.

Xiao Yan found a stool and stood under the vent. First, he carefully observed the vent. The filter screen is made into a fine mesh, which can be opened by screwing it to the side.

The fine net had no trace of opening, and the net could at most allow flies to pass through. Even if it was opened, the width inside could not even pass through the baby.

The bone shrinking skill was denied by Xiao Yan. But there is no explanation at all. How can a good living man disappear all of a sudden in this almost closed space?

Is it Yuan Shan who can escape? You ran away? That's impossible. She's a civilian in national security. The information shows that she doesn't have the ability to hide.

Xiao Yan stepped down a leg and was preparing to come down. He suddenly found that there seemed to be some white powder on the inside of the filter screen of the vent.

These powders are similar to the dust adsorbed on the air conditioner for too long, but they are whiter than the dust. There are also some substances formed on the surface like the plastic aging of the filter screen.

"Mr. Peng, how long have you used this ventilation system?" Xiao Yan asked casually.

"Soon, all the updated in April this year have been changed!" Peng Haiping was a little surprised. How could Xiao Yan ask these questions.

"Did you change the filter screen?" Xiao Yan asked again, pointing to the filter screen.

"Of course, because it's supporting!" Peng Haiping answered truthfully.

Xiao Yan nodded. The color of the outside of the filter screen is the same as the surrounding plastic, which should be changed together. But if it was updated in April this year, it would not be aging like this.

"Give me a sealed bag, the smallest one." Xiao Yan shouted below, and Qin Nan handed a bag up.

Xiao Yan opened the bag, then took out the Heavenly Master needle, stood it up, stuck it to the side of the filter screen and scraped it slowly.

As expected, the white powder particles fell gently into the sealed bag.

A moment later, Xiao Yan took the sealed bag of white powder and jumped down from the stool. He deliberately didn't lift his breath. When he fell, he stepped on the floor of the train a little heavy.

Sure enough, a faint white dust rose on the ground.

Xiao Yan's face was a little gloomy. He asked for a sealed bag, pushed away the sofa, and collected some white powder in the corner again.

They found that a thin layer of white powder fell on the surrounding corners and the floor, like flour.

At first, people thought it was dust, but when Xiao Yan collected it all, it was a little different.

"What is this?" Qin Nan asked.

Xiao Yan didn't answer. He opened the two bags and sniffed them gently. His eyebrows gradually wrinkled.

He threw the bag on the tea table, looked up at the vent and remained silent.

One of Qin Nan's two men picked up one and smelled it in front of his nose, but they didn't smell anything.

Qin Nan was a little dissatisfied with Xiao Yan. He raised his voice and asked, "you are talking. What are these things?"

"Yes..." Xiao Yan murmured.

"What is it?" Peng Dahai couldn't help asking.

"It's the ashes, Yuan Shan's ashes..." Xiao Yan said when he saw that the people were determined to ask.

"Ah..."

Several screams sounded almost at the same time. Qin Nan's two subordinates also killed people and beat drug dealers, but when they heard this, they threw out the sealed bag in their hands.

Qin Nan was also stunned. He picked up the sealed bag, looked carefully, smelled carefully, nodded his head and said, "it's really like the smell of ashes, but how can it be?"

"It's not possible, but impossible. If you cremate a person here, how can the surrounding things be intact?" Peng Dahai was naturally unwilling to accept this conclusion.

Xiao Yan did not answer them, but looked up again at the vent.

"Listen, is there a buzzing voice?" Xiao Yan suddenly asked.

Everyone pricked up their ears and the room became quiet. But only the sound of the train, and because the air conditioner in this house is off, there is no sound of the air conditioner.

Xiao Yan suddenly flew up and pulled his finger on the filter screen. When he fell, he took down the filter screen.

At the moment when the filter screen was opened, a small fire red bug flew straight out of the vent.
