"Compared to digging in the walls and digging holes in the ground, the amount of work is very small. Sechin said.

"In comparison, the workload is really negligible. Zu Yuji said.

"Negligible...... That's a bit exaggerated, isn't it, Xiaoyu?" Tang Ruoruo said.

"Not an exaggeration at all. ”

Zu Yuji said that if Tang Ruoru said this, he obviously did not have an idea of the workload of the dark passage and the dark room, even if it was approximate.

This is necessary to give her a bit of science. So Zu Yuji told Tang Ruoruo.

“...... If so, what do you think?"

After a long period of popular science, Tang Ruoruo fell into contemplation, and Zu Yuji saw that she had not moved for a long time, so she asked.

"I think...... The amount of work in the darkroom is not small. Tang Ruoruo said.

"So, that's it," Zu Yuji nodded, Ruoruo still understood very quickly (she explained for a long time, even if she was a stupid person, she probably understood, but Zu Yuji didn't realize that she had been talking for a long time), and said, "The dark passage and the dark room, digging up underground, the amount of work is not small." ”

"That's true. Tang Ruoruo nodded, this amount of work is really not small.

"So I said, remove the door and remove the door frame, this amount of work is really insignificant compared to this. Zu Yuji said.

"Well, Xiaoyu, what you said makes too much sense," Tang Ruoruo nodded, "This is not only insignificant, it is simply insignificant!"

Xie Qin watched the two girls talk for a long time, and shook his head secretly in his heart, you have to discuss this little matter, it is really ...... But when he thought about it, he had a quarrel with Ruo Ruo just now, and the quarrel was still a trivial matter, how could I be qualified to talk about them!

Alas, Xie Qin shook his head secretly, it's better to get down to business, concentrate on this, otherwise it will be dark later (you have said it several times...... It's still very stubborn this day).

So Xie Qin clapped his hands and said to Zu Yuji and Tang Ruoruo: "Okay, okay, let's get back to business." ”

"Well, okay. Tang Ruoruo nodded, if she didn't figure it out, she would keep asking, but now that she has figured it out, there is no need to dig deeper. So she simply agreed.

"Well, that's right. Zu Yuji nodded, "Brother Lingsheng, go on." ”

Xie Qin also nodded and said, "Then, let's go on." ”

He walked to the other side of the hallway, surveying the rooms on either side as he went.

Tang Ruoruo just heard Xie Qin talk about dismantling the door and dismantling the frame to relieve the door, Xie Qin didn't finish speaking, so she mentioned it again: "Brother Lingsheng, you just said that you just said that the door change, and you haven't finished talking about it." ”

"Oh, by the way," Sechin nodded, thought about it, and asked, "Where did I just come from?"

Tang Ruoruo looked at Xie Qin and said, "Did you say something similar before?"

"Oh no," Sechin shook his head, he was impressed, "you said it." ”

Tang Ruoruo was stunned, then nodded and said, "Yes, I said it, but Brother Lingsheng, you also said it, it's just that I said it first." ”

"yes, that's the point you said first. Xie Qin said.

"What!" Tang Ruoruo said dissatisfiedly, "What is the point of this!

"Of course, in order!" said Sechin dissatisfied.

Zu Yuji watched from the side, these two people were talking and talking and saw that they were about to quarrel again, so they hurriedly stopped and said: "Okay, okay, don't say it anymore, it doesn't matter who says it first, this is not the point in the first place!"

"What's the point?" Tang Ruoruo asked, turning his head.

Okay, Zu Yu Ji said in his heart, this is to forget about the business.

She shook her head secretly, and reminded her: "Ruoruo, why did you forget this, let's get down to business......

Zu Yuji stopped suddenly halfway through her words, eh, what did I say just now?

Hey, why didn't I even forget this! Jujube cake! Can this disease be contagious?

Seeing this, Xie Qin hurriedly said, "Ruoruo, what you just said was about changing the door. ”

He didn't want to keep arguing either.

"Oh, yes," Tang Ruoruo nodded, recalling, "I just talked about changing doors. ”

"Yes. Sechin nodded, and then his voice froze.

"What's the matter, Brother Lingsheng?" Tang Ruoruo asked, "You can go on." ”

"I can't say it," Sechin shook his head, "because I have a problem on my side." ”

"What's the problem?" Tang Ruoruo asked.

"I forgot where I said before. "Sechin said,

Tang Ruoruo was stunned, didn't he go back again?

Both fell silent, subtly.

At this time, the witty Zu Yuji stood up and broke the silence and said, "This problem is easy to solve." ”

"How to fix it?"

When Xie Qin and Tang Ruoruo heard this, they looked at Zu Yuji together and asked in unison.

"It's very simple," said Zu Yuji, "you just have to start from the beginning." ”

"......" Xie Qin was speechless.

At this time, Tang Jiaju interjected: "Xie Qin, you just said that replace the original door, tear down the door frame, and replace it with a new door, the material of this new door must be similar to the material of the surrounding walls." ”

"Oh, yes, yes!" Xie Qin clapped his hands and suddenly realized, "I remembered!"

You have a really good memory, Zu Yuji thought to herself, fortunately, the two people here are not stupid...... Wait, I feel like I'm in the dark! That's not going to work! Hmmm......

After a short period of thought, Zu Yuji had an idea.

Hmm!There you have it! Just count Brother Ringtone as half a fool!

That is, Xie Qin didn't hear Zu Yuji's heart, otherwise, he would definitely complain: You have been thinking about it for so long, but the result is not that Ruoruo is a stupid person!

But Sechin didn't know, so he didn't complain.

"yes, yes," he nodded repeatedly, "that's exactly that, yes, yes, yes...... I know what I'm going to say next, so wait, I'm going to organize the language first. ”

"Well, you organize. Tang Jiaju nodded.

Xie Qin thought for a while, and then said to everyone: "That's the case, why should the material be the same as the surrounding walls? ”

"What follow-up?" Tang Ruoruo asked.

"Paint. Sechin replied.

"Paint?" Tang Ruoruo was stunned when he heard this.

"That's right. If you want to use a new door that is close to the material of the wall, it is for this moment," Xie Qin said, his eyes wandering around the wall, "The so-called painting is to use it to be very similar to the original paint color on the wall, or simply the same color of paint, so that it is better to paint on the door." Speaking of which, you should understand what I mean, right?"

"Well, I do understand," Zu Yuji nodded, in fact, Xie Qin understood halfway through his words, "This is to disguise the new door panel as a wall, right?"

"Well, yes. Sechin nodded.

"But the walls are generally made of bricks, where can I find a door panel made of similar material to the turning head?" asked Tang Ruoruo.

"Anyway...... That's pretty much it. Xie Qin said leisurely, but after thinking about it, he said, "You can directly get a stone door." ”

"Slate door?" Tang Ruoruo was stunned when he heard this.

"yes, slate. Sechin nodded, this is indeed there.

"Hmm...... That's right, too. Tang Ruoruo nodded, because this is indeed there.

"I think that the Master of the Scepter Hall should be imprisoned in such a secret room, and there is a layer of such a disguise on the door. Sechin said to everyone.

Tang Jiaju said: "This ...... You can see inside from the window, right?"

Xie Qin said: "I think that the dark room where the master of the Xuanscepter Hall is imprisoned should be the same as the monitoring room, there are no windows. ”

"Well, that makes sense. Tang Jiaju nodded.

"So, how do you find such a dark room?" Tang Ruoruo asked.

"It's simple. Sechin replied, "Just pay attention to a few details." ”

"What details?" asked Tang Ruoruo.

"The first detail is the paint of the new door. Xie Qin said.

"Paint ......," Tang Ruoruo pondered.

Xie Qin said: "The paint of the new door, whether it is a similar color paint or the same color paint, will be different from the original paint, and you can see it if you look closely." Of course, this is based on the premise that the house is older. ”

"Otherwise?" Tang Ruoruo asked.

"In both cases, the paint can be avoided from being found. Xie Qin said.

"Which two?" Tang Ruoruo asked again.

Xie Qin said: "First, it is a new room, the new paint, because the time difference is not long, so you can't see it with the same type of paint; second, it is the same kind of paint to repaint the whole house, because it is the same time, the same paint, so you can't see the difference at all." ”

"Oh......" Tang Ruoruo nodded repeatedly, "I understand." ”

Xie Qin added: "The second detail is the scratches on the floor. ”

"Scratches. Tang Ruoruo repeated again, "What's so strange about this?"

Xie Qin said: "Under normal circumstances, this kind of new door is a flap door, the kind that is pushed open by hand and turned to the other side, and this kind of door will leave a semi-circular scratch on the ground after being pushed open for a long time, ah, if there is also one on the other side, it will be a circle when it is put together." ”

"Hmm...... Truly. Tang Ruoruo nodded.

Xie Qin added: "However, if it is not a flap door, but a secret door that is driven by a mechanism or an electric current, we will not see any trace, unless it is ......."

"Unless what?" Tang Ruoruo asked.

"Unless there happens to be something pressed under the door," Xie Qin said to Tang Ruoruo, "just like in the TV series, something is pressed under the door...... For example, a piece of stick. ”
