"My thoughts are...... Wrap a thread around it. ”

Jiang Bai explained his actions while operating.

He wrapped the thread he bought around the back of the key, and knotted the tip through a small hole. After securing the business, he wrapped a few more laps around the back of the key.

"Now the door is unlocked."

He said, "Close the door like this, and the line will pass under the door." ”

Che Hao, He Dazhuang and Du Yiheng observed in the room, while Yan Xiyue followed Jiang Bai outside.

Jiang Bai pulled through the line under the door and closed the door.

As he pulled the string, the rope that had been wrapped around began to spin the key.

"Smack"

With a very soft thud, the rope broke.

It just happened to be broken internally.

"It seems to be a bit of a mistake."

Jiang Bai said and opened the door.

"I see what you mean, pulling the key to rotate in this way is just right to lock from the inside?"

Cha Hao understood.

The rest of the people suddenly realized.

"And this kind of operation?"

He Dazhuang said with some surprise, "Although you failed, it should be feasible." ”

"I have a question, if you pull like this, won't there be traces of rope on the key after locking the door?"

Yan Xiyue thought about it and said, "Even if we can succeed, we should have discovered these things as soon as possible." ”

"yes, how do you explain that?"

He Dazhuang said according to Yan Xiyue's thoughts.

"That's why I use cotton thread."

Jiang Bai said, "The cotton thread can be ignited, and if it is ignited, then the whole evidence will no longer exist." I think the ash and burnt marks left on the key at that time must have been caused by cotton thread. ”

"You're okay with your train of thought, but why don't you give it a try?"

Che Hao said with a slight smile and motioned to Jiang Bai to light the cotton thread and try.

Jiang Bai lit the cotton thread from the outside, and the result was completely different from what he thought.

Originally, he thought that the flame of the lighter should burn along the cotton thread, but the actual effect was only a section of the cotton thread was slightly burned.

"Something must have gone wrong."

Jiang Bai pondered, "The flame should be right, the cotton thread needs to be changed." ”

"Although the cotton thread has enough strength, the speed of the fire is too fast, and there is no way to burn it down."

Che Hao explained, "It may be different if you change the material. ”

"How about more cotton threads?"

He Dazhuang said, "As long as it is thick, it can be burned for a while." ”

"No, it's a matter of material."

Yan Xiyue understood Che Hao's words, "What about oil?" I remember watching TV dramas in the past and there would be that kind of oil lamp! ”

"It's too slow, before the line is burned, the criminal police team members will come to open the door."

Jiang Bai shook his head, "It should be something that burns quickly...... Lead? ”

He remembers that when he was a child, firecrackers would have a fuse, which could not only burn along the way, but also have a certain strength!

"The lead should be fine, but I think the strength may not be enough."

Che Hao analyzed, "Upstairs is still under construction, so I'm looking to see if there are any materials for making leads." ”

He said and left, heading to the part that was still being renovated.

On the other hand, after Chen's mother returned to the villa, she was always a little uneasy in her heart.

He always felt that Jiang Bai's actions were faster than hers.

So he went to the secret place in the kitchen and made a call.

"Hello? Director. ”

Chen's mother heard the phone call, "Jiang Bai, how are they?" Do you want to speed it up? ”

"Well, a little, it looks like he's about to crack the secret room."

The director snorted, "Hurry up and take the final steps, they should find out soon." ”

"Director, I want to make sure, you're really going to help me, right?"

For the sake of insurance, Chen's mother confirmed again on the phone.

"Don't worry, I won't treat you badly."

The director paused as he spoke, "This matter is over, I promise you will definitely be able to go." ”

"Good!"

After Chen's mother hung up the phone, she left the villa.

In the Criminal Police Corps, Zhao Bin is putting the newly found clues and evidence into the reasoning of the entire case.

"How is it with Professor Che that they crack the secret room?"

He thought about turning to Liu Zifeng.

"I've just been contacted, and they've found the principle, and they need to study it again."

Liu Zifeng had just had a brief phone call with Che Hao.

The case is almost closed, but the suspect has not yet been identified.

Both Zhao Bin and Liu Zifeng believe that as the case progresses and more information is available, the murderer will naturally surface.

"Team Liu, are you interested in staying in Kyoto?"

There were only Liu Zifeng and Zhao Bin in the conference room at this time.

"This ......"

Liu Zifeng hesitated.

"I think your mobility and case-solving thinking are very good, and if you stay in Kyoto, you will have a greater development. This time, I have recruited many other local criminal police team captains, and I feel that you are the only one suitable to stay in Kyoto."

Zhao Bin said, "I may have to wronged you at first, and I will arrange you under my command as soon as possible." ”

This case not only requires the assistance of the captain of the criminal police team in other places, but also can be regarded as an assessment of absorbing excellent local captains.

Of course, he is optimistic not only about Liu Zifeng, but also about Jiang Bai behind him.

After these days of getting along, he felt that Jiang Bai's ability to solve cases was not inferior to Che Hao, and Jiang Bai was younger and had a bright future!

Jiang Bai and Liu Zifeng are from the same place, and Zhao Bin thinks that by "tying up" Liu Zifeng, he can "tie up" Jiang Bai.

According to the normal situation, the position of the Kyoto Criminal Police Corps is unattainable, and no matter how many members of the Criminal Police Corps break their scalps, they can't step into the gate of the Kyoto Criminal Police Corps!

But Liu Zifeng also made a mistake at this time.

"I feel like there's a lot of pressure on the team."

Liu Zifeng touched his head and said with a smile, "It may not be suitable for me for the time being." ”

He didn't think he could go to the Criminal Police Corps to do things, and he also felt a lot of pressure during this time.

Especially when he was "favored" by Zhao Bin, he made many other captains out of town a little jealous.

"I see, and I'm not going to force you."

Zhao Bin said and sighed, "If you want to come, I am always welcome, as long as I am still in this position." ”

"Thank you, Team Zhao."

Liu Zifeng said and saluted, "Right now, I still want to handle the case first." ”

He felt that Jiang Bai should not be able to stay in Kyoto for a short time, and the old captain's request was more important than Zhao Bin.

Jiang Bai must become a member of their criminal police team.

Only in this way will Liu Zifeng consider other things.

was even pulled into the criminal police corps with Jiang Bai.

That's all for later.

At the same time, Cha Hao found a lot of materials from upstairs and only made something similar to a lead.

"Try this."

Che Hao said and walked down the stairs, "Let's see if the thickness is enough, if you can't stuff it in, it will be troublesome." ”

Jiang Bai took the lead, passed through the hole of the key, and then tied it a few times.

Pull the thread out along the lower end of the door, just the right thickness.

You may feel friction when you pull it up, but you can barely use it.

"Try it."

Du Yiheng said, and walked into the door with He Dazhuang and Che Hao to observe.

Jiang Bai slowly pulled the lead again.
