If Bai Song were to handle the case of Shi's suicide by himself, he would not dare to think about it. There were at least four or five people who made important contributions to this case, which made Bai Song's final inference logical.

Bai Song was lucky to come across Zheng Can's clue, but it also proved that there should be more than two tons of bad money, and it must have flowed into the market through some other channels.

Two tons of money can be kept until it becomes moldy, and some will become poor and some will die of flooding...

However, considering the 26 billion yuan of Descartes Financial, Bai Song smiled and said, "Ha, it's just a small amount of money."

…

Bai Song went straight to the office, it was already dark. Because there was no rush, and Bai Song was more familiar with the nearby roads, Bai Song drove the car back to the road where he got stuck before.

It is very easy to drive this road with a four-wheel drive car with a quattro system. Of course, the most important thing is that the headlights are so bright that you can easily leave places with bad road conditions.

Compared with the urban area, Tianbei District is a little desolate. There are several prisons about two kilometers away from here, standing alone on the roadside. This is a no-fly zone for drones.

After crossing the road, Bai Song parked the car near the gate of the abandoned factory and found an inconspicuous place to park the car.

It was dark and there were not many cars nearby, so Bai Song went straight into the park through the gate.

The last incident with the black radio station gave Bai Song an idea, and today he came over eager to verify it.

The main positioning method of the drone also relies on GPS, so it is not more difficult at night than during the day, but the visual effect is a little worse. Bai Song walked to the bottom of the chimney, started the drone, and pointed it directly at the top of the chimney.

The drone climbed steadily upwards, and when it reached a height of 60 meters, the entire chimney came into view.

Some bricks had fallen off the top of the chimney. Bai Song controlled the drone to turn around and found the problem in the direction of the chimney facing the Economic Investigation Corps.

There is a palm-sized object here with a small antenna hanging on it.

The last time Bai Song went to southern Guizhou Province with Wang Liang, he had seen a full-band jammer, so he had a general understanding of electronic equipment. What is this here?

There is no way to take down the drone. This thing is not big, more like a small black radio station, but there are no wires, and no high-tech things like solar panels. This thing is rootless water. Bai Song looked at it carefully and made sure that the thing had run out of power and turned off.

In terms of its newness, this small device was installed not long ago. Because the wind is quite strong at this altitude, the sun and wind will make it look "weathered" in a few months. Baisong analyzed that the installation time did not exceed two months.

Seeing this, Bai Song had a general inference. The last time Baldy came here, he should have come here to change the battery of this device. Taking away some iron was simply to cover up this behavior. After all, if the police found out, if they didn't do something, they couldn't explain it clearly. And if they were caught stealing iron worth dozens of yuan in this abandoned factory, the punishment would definitely be very light.

I have to say that the bald guy still has some brains. If Bai Song was a local police officer who came here for patrol and discovered this situation, he would definitely be charged with theft.

After determining the location, Bai Song couldn't see it at all from below, so he could only control the drone to return.

Although the sound of the drone was not loud, Bai Song still felt a sense of peace after turning it off.

It's so quiet. The ground here is made of thick concrete. The factory wall is of ordinary construction, but the ground is very solid, probably for the passage of large trucks. After so many years, not even a few weeds grow here, and rats don't come here. There is only some moss at the bottom of the chimney.

Those who are a little timid may not dare to come here alone at night.

Bai Song looked carefully at the traces of sand and other traces left behind, making sure that no one had been there in the past few days. He walked around the chimney again and found the iron handrail to climb up.

Thinking of this, Bai Song felt a little strange. No matter what this thing was, since it was out of power, why didn't Baldy come to change the battery? Did its historical mission come to an end?

The iron handrails here are U-shaped, and the distance between each one is about one foot. Bai Song tried it and found that the iron had been rusted for a long time. When he applied a little force, the rust almost scratched his hand.

After testing his strength, Bai Song stepped onto the first iron handrail.

Wandering.

Bai Song was too heavy, weighing more than 170 pounds, and this old handrail began to shake. Bai Song even suspected that he could pull the handrail out from the cracks in the bricks if he exerted enough force.

This was definitely not an event that Bai Song could handle at his weight, so he had to withdraw.

Last time, Bai Song was far away and didn't see the process of these people climbing up, but after thinking about it, he was sure that it must be the short man among the five who did it. When they were eating ribs in the restaurant, this short man was one of the more honest ones.

After coming down, Bai Song prepared to restore the scene and bend back the handrail that had been bent.

The rust was too severe, and it was dark, so Bai Song scratched his hand when he exerted too much force, and blood flowed out.

…

Is this considered a public injury?

Bai Song thought about it and it seemed that there was no way to calculate it. The things on it were out of power and there was no need to worry about it for the time being. After dealing with it, Bai Song carried the drone on his back and left the scene.

After getting in the car, Bai Song looked at his wound carefully. It was quite deep. Although it had stopped bleeding, he could not be careless as he was injured by the rusty iron in this place. Bai Song searched and went directly to the nearest Grade A hospital.

Because it is a Grade 3 hospital, there were a lot of people there at that time. Bai Song waited in line for a while before he met the doctor.

"Where did you get this?" asked the emergency doctor.

"On the rusted iron." Bai Song answered truthfully: "It's rusted quite badly."

The doctor took a closer look and said, "You must get tetanus. A patient in our hospital died of tetanus yesterday."

Bai Song was shocked: "I want to get vaccinated, please give me a prescription."

While the doctor was operating the computer, Bai Song asked, "Doctor, can I ask what happened to the person you mentioned who died of tetanus?"

"I heard that he cut his hand while climbing a chimney, but he didn't come for the injection even though his hand was cut. After a few days, he gradually showed some symptoms, but his friends said it was fine. He didn't come until his myotonia and muscular dystrophy became serious. When he came to our hospital, he was basically beyond help." The doctor said, "This is the disadvantage of not getting vaccinated..."

Bai Song was speechless. That little guy was dead?

Although Bai Song didn't like these five people very much, he still felt a little shocked that they died like this. It was nothing more than meeting the wrong person.
