The aftereffects of this altitude sickness made Bai Song, who has always been relatively confident, feel the power of nature.

The human body needs oxygen, and not everyone can adapt quickly to the low-oxygen environment caused by low pressure.

Generally speaking, civil aircraft fly at an altitude of 7,000-12,000 meters. Once the cabin loses pressure, it will be the end of the flight, so the cabin will be pressurized. However, in order to reduce the pressure difference, the pressure in the cabin is generally reduced by 200 hPa, so that the atmospheric pressure in the cabin is approximately equal to the atmospheric pressure of a 2,000-meter mountain.

Normal people will be fine at an altitude of 2,000 meters as long as they don't do strenuous exercise, but starting from 3,000 meters, they will have altitude sickness. Every year, some people who travel to Sazhou City (3,600 meters) and Xiangge City (3,400 meters) suffer from altitude sickness.

Bai Song felt uncomfortable for the whole day. He woke up from sleep and felt confused. In short, he felt uncomfortable.

In his dream, Bai Song went abroad and dreamt about the source, step-by-step process and final outcome of this batch of white goods.

"What are you thinking about? You're even talking in your sleep," Wang Liang asked when Bai Song got up at night.

"It's okay, it's okay," Bai Song shook his head, feeling that his stomach was protesting severely.

"I ordered takeout for you. I ordered some porridge." Wang Huadong walked over with a bag.

"That's all?" Bai Song felt that this was not what he needed right now.

"Look, I told you so." Wang Liang took out a large plastic box from the box behind him, "Two pounds of braised beef."

Bai Song smiled and patted Wang Liang on the shoulder.

…

The competition, which was one day late, finally arrived as scheduled.

In the lottery, Tianhua City drew a better county - the crime rate was high, and of course, the proportion of this kind of points would be lower.

Bai Song and others have recently been in charge of the follow-up work of drug cases, which simply means tracing the source.

According to relevant clues, these people are just "donkeys" and the real controller has not been caught yet.

The three "donkeys" were all scared silly. They were all college students nearby!

"Have you read the law?" Bai Song asked.

"Officer...I..." Wang was very depressed: "I..."

"I don't want to hear this. If you were a little smarter and could provide me with some clues to catch my boss, it would definitely be good for you."

"I really... really don't know..." Wang was a little desperate.

Bai Song nodded and left the house.

He knew that these three people were dead.

24 kilograms, enough to be shot several times.

According to the original text of the Criminal Law, 50 grams is enough to be executed by shooting. Of course, 50 grams is just the starting point. The amount that can actually lead to execution is more than this. But no matter what, these three people have only one way out, unless they can give away the source of the problem.

Of course, handing it over to the upstream supplier does not necessarily save your life. It depends on how huge the contribution is. All we can say is that there is a slim hope.

However, it is obvious that these three people were purely used. For such a trip, each of them paid 50,000 yuan. Apart from that, they didn't even know what their parents looked like. All their contact was through the Internet, and those were all virtual numbers. One of them was even abroad.

"How is it, is there a way?" Sun Jie asked.

"No," Bai Song said, "These are all fools."

"It's as expected." Liu Shuyuan said, "If they knew where the online link was, they wouldn't do such a thing."

"That's true. So how do we check it?" Wang Liang asked. He was used to asking Bai Song.

"Do you think I'm a god?" Bai Song was speechless. "This kind of case is a national problem. The only way now is to see if the other party will take new actions. After all, they have suffered a huge loss this time. The real demand side will definitely continue to raise the price."

"Then it is most likely not a matter of City B. After all, Province B is so big. If they suffered a loss this time, they may avoid it next time." Huadong said.

"Yes, so we can only say that we have a long way to go. We can only leave this case here." Bai Song shook his head: "Let's go and look at other things first."

"Giving up just like that is not your style." Wang Liang said.

Bai Song ignored Wang Liang at all.

…

In the next few days, everyone started traveling mode, driving around on some mountain roads, under the pretext of looking for clues to the case, but Bai Song also knew that this was simply looking for a needle in a haystack.

A few days passed like this, and the few people finally got new tasks.

There is a special task force in Mo City. They discovered the lair of a fraud organization in District A of City B and need local support.

This matter does not require too many people's support. Remember that Bai Song went to Mo City to crack down on a den of scammers. It was all organized by the Jiuhe Branch. They drove a bus directly there. The main force of the arrests were police officers from Tianhua City, and the local area was mainly responsible for providing some technical support.

It happened that people from the Criminal Investigation Bureau were there this time, and Director Liang saw that Bai Song was a bit free recently, so he directly sent a few of them over to coordinate.

Originally, this kind of thing was not interesting, but Bai Song was still a little curious. A few days ago, Area A was searched by four or five hundred people. If there was a large scammer gang, there should have been some news.

After returning to the city, Bai Song got a clue and realized that these scammers actually rented a teaching building!

A local junior high school had fewer and fewer students enrolled in recent years, so only one of the several teaching buildings was in operation. So the school leaders rented out the other two buildings, one of which was full of scammers!

The fraud organization ran to the junior high school campus and rented a building, but these people did not interact with the students on weekdays. After all, junior high school students are still too young, so the fraud organization has strict confidentiality regulations.

These experts from all over the country explored many places, but they directly skipped places like junior high school campuses.

"Isn't this simple? It's an independent building with open space around it. They're just a bunch of scammers. Why don't we just rush in?" said the criminal investigation captain of Area A.

"Captain Liu, you don't know that the procuratorates in our big cities may be different from yours. The people in our procuratorates are very penny-wise! It's easy for us to arrest all these people this time, and it's also easy to detain them all, but if we want to approve their arrest, the chain of evidence must be complete! Although we have other evidence, we can't give them time to react. If some key evidence is destroyed, our future work will be in trouble!" Captain Shen of Demon City sighed.

Captain Liu could only nod his head: "Then we can only consider the time of the assault, or find a way to interfere?"

"The first floor of the teaching building has anti-theft windows and doors. If we raid it, it will take at least a few minutes," said Captain Shen. "Our idea is that the scammers' working hours are from 2 pm to 2 am. We will wait for them to get off work and then start the raid. Before that, we will gain control of their cameras."

"It's physically isolated inside, that's impossible." Wang Liang shook his head: "And it's infrared, it may not be effective at night."
