Police Detective

If Bai Song remembers correctly, the elevator the two took this time was the same one they took when they went down, but the elevator inside became a woman.

　　 This is really a problem in itself. As far as the flow of people in this hospital is concerned, there is no need to equip all four elevators with elevators. Two equipped, the other is not equipped but the optimal solution.

　　 Therefore, Bai Song always felt that there was a problem last time. This time I basically found it, but it is still uncertain.

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

　　 "This hospital is really ill," Bai Song murmured again: "There can be four elevators, but nobody charges parking fees."

　　 "I do feel that there is a problem, but there is no direct evidence yet." Liu Shuyuan rubbed his temples, thinking about how to arrange the next step.

　　 "I think the laboratory is not on the 10th floor. The 10th floor is fake. It is very possible that your elevator will stop on the 9th floor." Bai Song said.

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

　　 This car window glass is also one-way, with a film attached, so you can't see the inside from the outside, but Liu Shuyuan still has a feeling of being seen by others.

　　 The place in the hospital itself is a bit gloomy. Thinking of the unknown behind this, Liu Shuyuan can feel the extra coolness. But on the contrary, there was a raging fire in his heart, and he couldn't wait to know the secret inside.

　　 "I always think someone will pay attention to us." Liu Shuyuan said: "Should we go back and change a car?"

　　 "It's okay, we won't come later." Bai Song drove the car out of the hospital, and parked the car in a clearing near the prison.

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

　　 The red flag of Bai Song was particularly conspicuous. Just as he was about to stop, two policemen surrounded him. Bai Song said that he was in trouble—the two had disguised themselves, but they did not match their documents. The main reason is that there are not all police around here, it is troublesome to explain, and it is easy to expose.

　　 Thinking of this, Bai Song didn't stop the car, and drove away from here. The police stopped watching the car go away.

　　 "You policemen can't do it," Bai Song joked, "When we saw the police, we drove away, but the police didn't chase them."

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

　　 "Um..." I can't answer these words...

　　 Bai Song coughed and drove to a nearby empty place.

　　 "Just here, here is clean." Bai Song parked the car.

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

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

　　 "The main reason is that I am afraid that the grass will startle the snake", Bai Song said: "Even if I don't walk up the stairs, I still have a way to confirm the floor."

　　 Bai Song looked around, there was no one around, went to the trunk and took out the telescope.

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

　　 Soon, Bai Song adjusted the position, after watching for more than half a minute, he exhaled deeply: "OK."

　　 Liu Shuyuan was itching to hear, and hurriedly moved in.

In the whole field of vision, there is a piece of glass, that is, a piece of glass on the outer curtain of the building. The glass is very complete. Liu Shuyuan is not very good at operating this telescope, and he does not know how to adjust the horizontal and vertical position. ?"

　　 "Look at the lower right corner of this glass, you can see a faint black mark of three or four centimeters in it, which is very unclear, but it is different." Bai Song reminded.

　　 "Oh oh oh, it's true, but I don't know exactly, what is this?" Liu Shuyuan raised his head and looked at Bai Song.

　　 Bai Song did not speak, 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, the privacy film of this car is still 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 reason why one side can see the other side and the other side can't see it is the most important thing about the film's ability to pass incident and reflected light. And the refraction is different. This kind of film is multi-layered. After the refracted light passes through different media, the real look 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 escaped, allowing us to see a mark."

　　 "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 on the windowsill." Bai Song said relaxedly: "From here, this table tennis racket is on the 12th floor."

Ping pong paddle…

　　 Liu Shuyuan was reminded of this, and also remembered.

　　 There are seven or eight people playing at the table tennis table. If they lose, they change. After the two people saw that the uncle who had won six or seven rounds in a row lost, it would take half an hour to think about going up.

　　 Liu Shuyuan always felt that he was also very careful, but he was still very shocked. He couldn't help but look at Bai Song a little bitterly, feeling very sad.

　　 Liu Shuyuan’s growth can be said to be smooth. Although he has met many great people, most of them are elders and professors, who are older than him~www.wuxiaspot.com~ he can accept it. But Bai Song is one year younger than him! The most important thing is that Bai Song, like him, came to this hospital twice, and the two were together the whole time!

　　 Whether it was the last time or this time, there are always things that are commonplace that can be found by Bai Song as clues, but he can't. This is quite frustrating.

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

　　 "I'll do it myself." Liu Shuyuan is still able to remove makeup, got into the cab, and got makeup remover and cotton from Bai Song.

　　 The makeup and disguise of Master Qiao are not the same as those outside, but the ones that remove makeup are ordinary makeup removers. The two quickly "tipped" the disguise on their faces.

　　 "Next, find someone to confirm." Bai Song sat in the co-pilot and looked at Liu Shuyuan: "The matter here must be under the jurisdiction of the Tianbei Branch."

　　 "That's for sure." Liu Shuyuan heard this, with a pretty good spirit: "I'll solve it."
