"It's always me who asks, 'Where did I just say?', and then you tell me, 'You just said blablabla......,' and then I suddenly realize, 'Oh, that's it, I forgot,' and then everyone is happy!"

"Everyone is happy about this!" Tang Ruoruo exclaimed dissatisfiedly, "There is no meaning of celebration at all!"

Xie Qin shouted: "Why is there no more! It is only by asking like this that there is joy, ah no, everyone is happy, how can there be any joy!"

"Isn't joy the meaning of joy!" Tang Ruoruo shouted.

Xie Qin shouted: "Who did you learn the language from! Joy and joy are not the same word!"

"But the meaning is always similar!" Tang Ruoruo shouted.

"The meaning is not similar!" exclaimed Sechin.

"How can it not be similar!" Tang Ruoruo shouted, "I'm afraid you're not lying to me!"

"I didn't lie to you! I really didn't mean it!" exclaimed Sechin.

"No, I don't believe it, you're lying to me!" Tang Ruoruo shouted.

"Ah," Xie Qin suddenly reacted, "we got off topic!"

"Did you just react!" Tang Ruoruo shouted dissatisfiedly.

"Did you react?" exclaimed Sechin, "you reacted and you didn't warn me?"

"Why should I remind you!" Tang Ruoruo shouted.

"Anyway!" Xie Qin waved his hand, "No matter what!" 'Where did I just say' This is all I said first, and you, as the person being asked in the general routine, don't even know that this is your disqualification!"

"What the hell!" Tang Ruoruo shouted, "Brother Lingsheng, what are you talking nonsense!"

"I'm not talking nonsense!" exclaimed Sechin.

"Still say no!" Tang Ruoruo shouted, "If I hadn't reminded you just now, you wouldn't have remembered what was going on!"

"Who said that!" exclaimed Sechin, "besides, you have reminded me, why didn't you tell me!"

"Tell you what?" Tang Ruoruo was stunned when he heard this.

"Tell me what I just said, of course. Sechin said.

"Why are you still struggling with this ......!" Tang Ruoruo suddenly became angry and didn't fight, "I kindly reminded you just now, you actually said it!"

"I don't need you to remind me, slightly. ”

Xie Qin grimaced at her, but it was not visible in the gas mask.

"I'm ignoring you too!

Xie Qin looked at Tang Ruoruo's face (gas mask) and couldn't see anything, but listening to the voice, she might be grimacing as well.

This gas mask is really troublesome, he thought to himself, not seeing other people's faces......

Just when the two were arguing inexplicably, Tang Jiaju interjected in time: "Xie Qin, you just said that by modifying the existing room, a dark room can also be created." As for the way to create it, you haven't finished talking about it yet. ”

“...... Ahh

When Xie Qin heard this, he immediately reacted.

Thanks to what he said, otherwise Xie Qin and Tang Ruoruo would have to continue to quarrel over some inexplicable.

Sechin breathed a sigh of relief, anyway, it's always good that way.

He quickly used his brain and thought about it for a while.

"Well, I remember," Sechin nodded, "I finally remember." ”

"If you still can't remember this, I'm afraid you're going to enter Alzheimer's disease in advance. Tang Ruoruo snorted and said disdainfully.

"Uh......" Sechin was momentarily speechless.

"I'm really too lazy to quarrel with you anymore!" Tang Ruoruo shook his head vigorously, "Brother Lingsheng, you better hurry up and get down to business, otherwise it will really be dark in a while!"

"Xie Qin, tell us what the hell is going on. Tang Jiaju said.

"Hmm...... All right. ”

Xie Qin calmed down.

"Well, you can create a darkroom by modifying an existing room, and it's very easy to do that. He said to the people.

"Oh......" Tang Ruoruo nodded, as if he understood.

"So, what specific modifications should be made?" Tang Jiaju asked, "Xie Qin, can you give some examples?"

"I was about to say that. Xie Qin smiled, "It's really very simple, and there is a way to do it, which is to replace the door." ”

"Replace the door?" Tang Ruoruo repeated.

"Yes. ”

Sechin said, turning around and striding towards the other side of the hallway.

"Replace the original door, tear down the door frame, and replace it with a new door, which is more similar to the material of the surrounding walls. ”

"Oh......" Tang Jiaju nodded, as if he had realized.

"Replace the door, and tear down the door frame?" Tang Ruoruo said, "This is not a small amount of work, right...... And it's not easy. ”

Xie Qin shook his head and said: "Compared to digging in the wall and digging a hole in the ground, the amount of work is already very small. ”

"Hmm......" Tang Ruoruo thought again.

"Well, in comparison, the workload is really small and negligible. Zu Yuji said.

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

"It's not an exaggeration," Zu Yuji shook her head, "If you can imagine how much work it takes to dig a hole in the wall and dig a secret passage—you know, the secret passage must extend a long distance outward, and it is impossible to make an exit at the door of the house, this is simply impossible." ”

"Well, yes. Xie Qin nodded in agreement, "Xiao Yu is right. ”

"But......" Tang Ruoruo thought for a moment and retorted, "What we're talking about now isn't a secret passage, right?

"It's the same with the dark room. Zu Yuji said, "The workload is not much smaller. ”

"It's much smaller, it's better. Tang Ruoruo said.

Zu Yuji said: "It's not small at all, let's just say it, we don't count the secret path in it." ”

"Didn't you say there was no more?" asked Tang Ruoruo.

Zu Yuji said: "Under normal circumstances, there is no direct digging of a dark room under the house, because it is easy to be discovered, and the ground is empty, so walking on it must be different from the solid one." And it's not safe. ”

"Isn't it safe?" asked Tang Ruoruo.

"It's not safe. Zu Yuji nodded, "Because in this way, the dark room is directly under the ground on the first floor, which is essentially digging the foundation of the house." ”

"Foundation?" Tang Ruoruo asked again.

Xie Qin looked at her, and said in his heart, why don't you understand anything, are you the legendary problem baby?

Zu Yuji said: "It's the foundation of the house, it's all necessary, if the darkroom is built on this, isn't it hollowed out? If it's just a little space, it's fine, but the darkroom has never been so small, at least it has to be as big as a room." ”

"Well, that's ......," Tang Ruoruo nodded.

Zu Yuji said: "So the problem comes, a dark room the size of a house, under the house, then the whole room is hollow underneath, think about it, if you walk on it, when do you think the ground will suddenly collapse?"

"I think...... It's possible," Tang Ruoruo nodded heavily, "It's too likely." She said with a look on her face that became a little uneasy, as if she had really walked through it. "If this suddenly collapses and falls into the dark room, it must be very painful to fall so high. ”

"It hurts?" Zu Yuji glanced at Tang Ruoruo, "It's not just that it hurts, it's already very lucky to be in good condition." ”

"Also...... Also. Tang Ruoruo nodded.

Zu Yuji said: "So, this is very dangerous. The safe way to do this is to open only a small part of the dark passage, and then lead to another place, where there is no foundation, and then build a dark room to come out. In this way, it will not attract attention, and there is no need to worry about sudden landslides while walking. ”

"Indeed......" Tang Ruoruo nodded.

"But let's assume that first. Zu Yuji said suddenly.

"What hypothesis?" Tang Ruoruo was stunned and asked.

Zu Yuji replied: "Since you say that the workload of the dark room is smaller than that of the dark passage, then let's make a hypothesis, assuming that there is no such a small section of the dark passage, it is directly the dark room, under the house." If you roughly calculated, how much work would be required to dig out such a large dark room, and how small would it really be to dig out a dark tunnel?"

Tang Ruoruo thought about it.

Zu Yuji didn't wait for her to answer, and said: "And if you want to know one thing, it is that the dark path does not need such a large space, and its engineering quantity lies in the distance is too long. ”

"Hmm......" Tang Ruoruo nodded and began to think again.

Zu Yuji waited for a while, and when she saw that she still didn't speak, she asked, "Ruoruo, what do you think?"

"I think...... The amount of work in the darkroom is not small. ”

This was originally a fact, so Tang Ruoruo quickly figured it out (probably), she nodded as she said.

Zu Yuji said: "So, that's it, the dark passage and the dark room, dug 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 shook his head secretly, thinking to himself, you still have to discuss this little matter, compare, talk about it for a long time, it's really ...... At this time, he thought about it, hey, they are at least discussing related topics, and the trivial things I just quarreled with Ruo Ruo are really useless!

Alas, Xie Qin sighed heavily, just rushed this matter, I am not qualified to talk about them!

Alas, speaking of which, although it is not qualified, the nature of these two things is really the same.

- What a waste of time!
