Xiru felt that he didn't have the ability to judge the depth of these two people's sleep. As long as one person has a whole eye, it's over. So what to do?

Hiru sat in his office and began to think of ways to do it. First of all, a thought popped into his mind, what about some medicine? It's not difficult to get some sleeping pills, as long as you go to the clinic and say that you haven't slept well recently, then you can prescribe it. After the sleeping pills arrived, I crushed the sleeping pills into powder and brought them to the unit. These two tea drinkers, in fact, almost all the security guards on night duty, are tea drinkers.

Then find an opportunity to pour the powder into the cups of these two people. In this way, they should be able to sleep more soundly at their posts.

How many drugs can be given? If there is too much, they can detect it themselves, and if there is less down, it may not work. It's still a bit tricky. I am not a doctor, so I can't estimate the drug resistance of these two people.

That's not drugging...... Drinking. As soon as this idea came to him, Xiru immediately dismissed it. Because of his previous working hours in the pseudo-middle reserve, he has never drunk alcohol. If you drink rashly this time...... But it's counterintuitive. Maybe someone will be able to see what happens the next day.

After thinking for a while, Xiru fell asleep in a daze. Waited until the next morning. I got up pretty early. Trained a circle of posts again. All the security guards got up. Okay, let's do it first. Anyway, didn't the one called Lao Tai say that if you don't have a chance, don't start easily.

When it was time to hand over the shift, Lian Yishan came on time, and the two of them opened the vault again and walked around. Lian Yishan finished signing the shift record, and Xiru was off work.

Out of the pseudo-Zhongchu, I was not in a hurry, and I met a big Shandong bun seller on the street. I bought a dozen or so, and I can eat it today. Save cooking. After a while, he came to the entrance of his alley, and drew a small horizontal path on the wall with the small turn of his head in his hand. It's as if you were holding your hand on a wall, and you can draw it as you walk inside.

After returning home, Xiru was not in a hurry, smoked a cigarette, took out the leftover food from yesterday, put it on the table together, and then started to make!

I was sitting in the hall eating steamed buns when I heard a knock at the courtyard door and someone walked in. There are two in total, one of which is Bai Fengtai. The other Hiru hadn't seen it.

After plugging the courtyard door, Bai Fengtai and the two walked in. Bai Fengtai said: "I saw the signal you left, I originally wanted you to know someone today, so today is just right." Did you get it? ”

Xiru said: "Why did you come empty-handed today? As he spoke, he stuffed the rest of the bun into his mouth and took out the clay locket from his pocket.

Bai Fengtai pointed to the small box and said, "Look at it." ”

He was speaking to a man he had brought with him, who was about forty years old, not fat or thin. I haven't spoken since I came in, and I seem quite quiet.

Hearing what Bai Fengtai said, he reached out and took the small box in his hand and opened the lid. After looking at it, he said, "Well, this should be the handiwork of Sakura Lock, which is mostly used on portable metal boxes." But it's the old style, their latest style, on the metal box, in addition to the mechanical lock, but also added a manual mechanical combination lock, four, five, six digits. However, this kind of metal box is a kind of insurance transit box used when transporting important things or documents. ”

Bai Fengtai listened and asked, "Then this kind of lock, is it easy to open?" ”

"Simple." The man said: "I said that this is an old style, and the new style is actually not difficult to open." This kind of lock is far away, and there is actually no difference from ordinary locks. It's all about the relationship between the key and the cylinder. If it were me, if I had the tools, it would be open in a few seconds. ”

Bai Fengtai nodded and said, "Then if you teach it to a layman, how long do you think he can learn." After learning it, how long will it take to open this kind of lock? ”

After hearing this, this person thought for a moment and said, "It's hard to say." How long does it take to learn...... Look at this person's understanding, some people hurry up, some people slow down. In addition, I have to buy a few more lock cylinders with the same principle, and I will teach him how to open them. Then let the other party practice. The more familiar you are, the faster you will definitely be, and it depends on whether the other party can work hard to practice. Also, how long is there to practice. If you are willing to put in the effort to practice, within a week, it is a single lock...... Well, in ten seconds. I'm talking about ordinary people. ”

Bai Fengtai let out an "um". Then he said, "I forgot to introduce you two." This is Tan Manzai, you can just call him Lao Tan. Then he pointed at Xiru and said, "This is your student, Xiru." ”

Tan Manzai looked at Xiru and asked, "Did you have no foundation in this area before?" ”

Xiru said: "Who will touch this thing." Never. ”

"Okay." Tan Manzai said: "Then I will go out to prepare something, it shouldn't be too long." Within an hour it was about the same. ”

"Okay." Bai Fengtai said: "Then you go." When you come back, I may have already left, you just teach him. ”

"Understood." Tan Manzai replied, turned around and walked out the door.

Xiru raised his chin outside the courtyard and said, "This is also your people?" ”

"That's right." Bai Fengtai said: "He has studied all kinds of locks on the market. Even locks that include safes. So you have to learn from him. According to him, this kind of lock, if you want to open it, it is not very difficult. ”

Xiru said, "Well, I'll try to learn it this morning." It's better to go to Chongqing early to see my wife and children. ”

Bai Fengtai said: "Do you feel that when you go to work, do you have any opportunities, or ideas? ”

"I thought about this last night. I had a few thoughts...... "Then he told Bai Fengtai about what he considered last night."

Bai Fengtai listened, waved his hand and said, "I don't think it's okay, don't think about drinking." Not in line with your original habits. As for drugged...... Like you said, it's not good to go down too much, and it's not good to grasp the amount if you go down less. If one is not good, it may be discovered immediately the next day. In this way, there will be little or no safe time for you to leave Shanghai. ”

When Bai Fengtai said this, he paused, thought about it in his mind, and said, "I think it's better to start in the morning when you are on shift and when you inspect the vault." I heard you say that every day I walk around the vault with that Lian Yishan......"
