Police Detective

If Bai Song remembered correctly, the elevator the two of them took this time was still the same one they took last time, but the elevator attendant inside became a woman.

That in itself is really problematic. With the amount of people in this hospital, there is actually no need for all four elevators to be staffed with elevator operators. Two are equipped, and the other is not equipped, which is the optimal solution.

Therefore, Bai Song always felt that there was something wrong the last time he came here. This time he basically discovered it, but he was not sure yet.

There were still many people on the first floor. The two slowly left the hospital and got into the car. Bai Song took a deep breath.

"There's something really wrong with this hospital," Bai Song murmured again, "There are four elevator attendants, but no one charges parking fees."

"I do feel there is something wrong now, but there is no direct evidence yet." Liu Shuyuan rubbed his temples, thinking about the next step.

"I don't think the laboratory is on the 10th floor. This 10th floor is fake. It's very likely that your elevator will stop on this floor if it's on the 9th floor." Bai Song said.

"So, the laboratory is actually on the 9th floor, and there are two floors between the 7th floor. What we call the 13th floor is actually the 12th floor." Liu Shuyuan sat in the back of the car and observed this from the window glass. building.

The car window glass was also one-way and was covered with film, so the situation inside could not be seen from the outside, but Liu Shuyuan still felt like he could be seen.

The hospital itself was a bit eerie. Thinking of the unknown things behind it, Liu Shuyuan could feel an extra chill. But in contrast, there was a burning fire in his heart, and he couldn't wait to know the secret inside.

"I always feel that someone will pay attention to us." Liu Shuyuan said: "Should we go back and change cars?"

"It's okay, we won't come again." Bai Song left the hospital and parked the car in an open space near the prison.

There are several cars waiting here, and there is also a police car.

The red flag of Bai Song's car was particularly conspicuous. Just as he was about to park the car, two policemen surrounded him. Bai Song thought that he was in trouble - the two of them had disguised themselves, but it didn't match their IDs. The main reason is that there are not all police around here. It is very troublesome to explain and easy to expose.

Thinking of this, Bai Song drove away without stopping the car. The policeman stopped as he watched the car go away.

"You police are not good enough," Bai Song joked, "When we see the police, we drive away, but the police don't chase us."

"Someone knows this car." Liu Shuyuan said calmly.

"Uh..." I can't answer this...

Bai Song coughed and drove to a nearby deserted place.

"Just stay here, it's clean here." Bai Song parked the car.

There are a lot of trees here, and they are one or two hundred meters away from the gates of the prison and the hospital. The two of them analyzed the problem carefully.

"Why don't you take the stairs to confirm?" Liu Shuyuan said, "I don't think there is any danger."

"The main reason is that I'm afraid of alerting the enemy," Bai Song said, "Even if I don't take the stairs, I can still confirm the floor."

Bai Song looked around and saw that no one was around, then went to the trunk and took out the binoculars.

The straight-line distance from the hospital building is more than 500 meters. It is very clear to see the windows with a telescope at this distance, especially when there is no smog today.

Quickly, Bai Song adjusted his position, looked at it for more than half a minute, and took a deep breath: "OK."

Liu Shuyuan felt itchy after hearing this and quickly came over.

In the entire field of view, there is a piece of glass, which is the outer glass of the building. The glass is very complete. Liu Shuyuan is not very good at operating this telescope and does not know how to adjust the horizontal and vertical directions. He can't help but wonder: "What's wrong? This is ?”

"Look at the lower right corner of the glass, you can faintly see a three to four centimeter black mark inside. It's very unclear, but it's different." Bai Song reminded.

"Oh, oh, there really is one, but I'm not sure, what is it?" Liu Shuyuan raised his head and looked at Bai Song.

Bai Song didn't say anything, opened Liu Shuyuan's rear door, and reached into the car: "Can you see my hand like this?"

Liu Shuyuan shook his head: "I can't see it, but the privacy film on this car is pretty good."

Bai Song then put his hand on the car glass from the inside, and then asked: "Can you see my hand like this?"

"I can see it." Liu Shuyuan seemed to understand something.

"This kind of coated glass is not purely one-way glass. The main reason why one party can see the other party but the other party cannot see it is the ability of this film to pass incident light and reflected light. And refraction is different. This kind of film is multi-layered, and the refracted light passes through different media, so the true appearance of the inside cannot be seen from the outside." Bai Song explained: "But if you are very close to the glass, there will still be A small amount of reflected light escapes, allowing us to see a seal."

"So, what is this seal you are talking about?" Liu Shuyuan understood what Bai Song wanted to express.

"The uncle's table tennis racket is placed on the window sill." Bai Song said easily: "Looking from here, this table tennis racket is on the 12th floor."

Ping pong paddle…

Liu Shuyuan was reminded and thought about it.

There were seven or eight people taking turns on the table tennis table, and when they lost, they would change players. After the old man they saw, who had won six or seven rounds in a row, lost, it would take him half an hour to think about how to play again, so...

Liu Shuyuan always felt that he was quite attentive, but he was still very shocked. He couldn't help but look at Bai Song sadly, feeling very sad in his heart.

Liu Shuyuan's growth can be said to be smooth. Although he has met many outstanding people, most of them were elders and professors who were older than him, and he could accept them. But Bai Song is still one year younger than him! The most important thing is that Bai Song came to this hospital twice, just like him, and they were together the whole time!

No matter it was last time or this time, there were always some common things that Bai Song could find as clues, but he couldn't, which was quite frustrating.

"What's wrong with you?" Bai Song was a little confused. At this moment, he had put away the telescope, "I'll take off your makeup."

"I'll do it myself." Liu Shuyuan still knew how to remove makeup. He got into the cab and got makeup remover water and cotton pads from Bai Song.

Master Qiao's makeup and disguises were different from those outside, but the makeup removers were ordinary makeup removers, and the two of them quickly "removed" the disguises on their faces.

"Next step, find someone to confirm." Bai Song sat in the passenger seat and looked at Liu Shuyuan: "The matters here must be under the jurisdiction of Tianbei Branch."

"That's for sure." Liu Shuyuan was in good spirits after hearing this: "I'll solve it."
