After Xie Qin finished inspecting one side of the corridor, he led the group back to the middle of the staircase, that is, the middle of the second floor, the middle point of the corridor on both sides, and everyone followed behind, looking at each other, not knowing what he wanted to do.

"It's time to look at the other side. Sechin said to the crowd.

Tang Ruoruo couldn't help it, so he stopped him behind and said, "Brother Lingsheng, I really don't understand, what do you want to do?"

Xie Qin turned his head to look at him, smiled and said, "You'll understand later." ”

"I don't think I'll figure it out later. Tang Ruoruo shook his head, "Unless you tell me one by one." ”

Xie Qin smiled and said, "Of course, Ruoruo." When I figure something out, I'll tell you everything and tell you. ”

"Figure out something?" Tang Ruoruo repeated.

"That's right. Sechin nodded, "To be exact, I still have some things to verify...... Although, the guard had already indirectly told us the answer, but the exact location ...... We'll have to find it ourselves. ”

"What did he say?" asked Tang Ruoruo.

"It doesn't matter what he says," Sechin shook his head, "what matters is his reaction." When I mentioned the second floor, his reaction was clearly the panic of only those who had seen through the mystery. His reaction confirmed that the Scepter Hall Master was indeed imprisoned here, on the second floor. ”

Tang Jiaju and Tang Shuyan nodded together, and the guard's reaction really meant this.

But the question is, how can there be a secret passage on the second floor?

Sechin turned around and continued walking.

"I just thought about something. He said.

"I know, you mentioned a flash of inspiration...... Something. Tang Ruoruo said.

Xie Qin nodded and said, "Yes, that's what I'm talking about. ”

Tang Ruoruo said: "Then what do you want to say......"

"I suddenly remembered to open a show I had watched before. Xie Qin suddenly said something seemingly irrelevant.

Tang Ruoruo was stunned, he didn't expect him to suddenly talk about this.

"What show?" she asked subconsciously.

Xie Qin said: "I forgot the specifics, but in this TV show, it does mention things about secret passages, secret rooms, and so on." ”

"Oh......"

Tang Ruoruo nodded, at first she didn't pay attention to it, she just thought it was the kind of program that used her imagination to talk nonsense, but after thinking about it, since this show inspired Xie Qin, it must be worth mentioning.

So Tang Ruoruo said to Xie Qin: "Brother Lingsheng, what inspired you about that show?"

Xie Qin turned his head to look at Tang Ruoruo and said, "Actually, it's very simple, spaces like dark rooms and secret passages are not just limited to that kind of ...... Anyway, they don't just dig a place out of the wall, or dig a hole in the ground, there's a lot more to it. ”

"Uh...... All right. Tang Ruoruo nodded, Xie Qin's words were very subtle and incomprehensible, she had to think about it carefully before she could digest it.

Xie Qin added: "Another common way to create a darkroom is through the modification of a ready-made space. ”

“...... What do you mean?" Tang Ruoruo asked, she couldn't understand what she said.

"Meaning," said Sechin bluntly, "can create a dark room by modifying the existing room." ”

When Tang Jiaju and Tang Shuyan heard this, they both showed expressions of understanding.

"And the way to create it is very simple, as long as it ...... Oops, why am I dizzy......?"

As he spoke, Xie Qin suddenly felt a wave of dizziness.

"Hey!" Tang Ruoruo patted his head, "We patronized to find the third uncle, but we forgot a very important thing!"

"Mixiang!" Zu Yuji also reacted, "The second floor is still ventilating!"

"That's right!" Tang Ruoruo nodded, "Dad also said that he won't be able to come up again for a while!"

“...... I really forgot," Tang Jiaju shook his head, "I'm too anxious!"

Tang Shuyan said: "Let's quickly put on the gas mask." ”

The people still wore gas masks on their bodies, and when they heard this, they immediately put them on their heads again.

"Will I have heat stroke again this time?" Tang Ruoruo said.

"Huh, what heat stroke?" Sechin hadn't reacted yet.

"I mean, heat stroke. Tang Ruoruo said, "Didn't I have heat stroke just now, Xiaoyu almost suffered from heat stroke!

Tang Jiaju said: "It's talking about what happened just now." ”

"Ah!" Xie Qin reacted immediately, in order to "bury" the truth of the sobering pill, everyone was still hiding from Tang Ruoruo, and hurriedly said, "Oh, you're talking about this!"

"Well, yes. Tang Ruoruo said, "Brother Lingsheng, do you think we will have heat stroke again this time?"

Her voice was in the gas mask.

"It should ...... No," Xie Qin shook his head, "The heat stroke just now was due to the lack of air circulation in the secret room, and the air contained a lot of carbon dioxide, and the temperature was too high, resulting in ......"

"Okay, okay, Brother Lingsheng!" Tang Ruoruo waved his hand again and again, "Don't show off your meager chemical knowledge again!"

"Ugh!"

Xie Qin was speechless, he was robbed by Tang Ruoruo, he remembered the story of being slapped in the face by Tang Ruoruo just now, and his face suddenly turned red, fortunately, he couldn't see anything in the gas mask.

In order to avoid this embarrassing atmosphere (which Xie Qin thought he had), Xie Qin said again: "That...... Anyway, now we're in the hallway, not in a small space, and the air circulation is good, so I don't think we will get heat stroke anymore. ”

Saying so much is all a lie, Xie Qinxin said, in fact, because of the sobering agent, if there is no sobering agent, Ruoruo will not be "heatstroked" at all.

But that can't be said, if there is no sobering agent, then how can you wake up a comatose person!

"Alright, alright. Tang Ruoruo waved his hand, "What are you doing this time, showing off your knowledge of physics, huh?" he glanced at Xie Qin as he spoke.

"Ah...... Well. Sechin nodded, "I'm also an air flow student, isn't it?" Hahaha...... said with a dry laugh.

His embarrassing smile made everyone uncomfortable, Tang Ruoruo had goosebumps, shook his head, and sneered: "What about 'mobile learning', Brother Lingsheng, you can really hold yourself high." ”

"That's oh!" Sechin nodded, he knew very well that he had to be cheeky to ease the awkward atmosphere of the scene at this time.

"Come on," Tang Ruoruo shook his head, "Don't say it, don't say it, I know you have excellent grades in science, okay." ”

It sounds like he is praising Xie Chin, but anyone who knows Xie Qin knows that his science grades are very problematic, not only are he often wrong in chemistry, but his scores in mathematics and science are often in the tens of figures, and in the case of a perfect score of 15, his score is still below 60 points, that is, he does not pass at all.

Tang Ruoruo knew Xie Qin's miserable achievements, so she was not praising him at all, but hacking him.

Of course, Xie Qin also knew what Tang Ruoruo meant, and he was very embarrassed, but at this time, he could only smile cheekily: "It's okay, it's okay, hehe." ”

Except for Zu Yuji and Qi Buji, everyone didn't know the inside story, but they still guessed one or two from Xie Qin's embarrassed smile, and similarly, Xie Qin's embarrassing smile made them uncomfortable.

Tang Ruoruo shook his head, not planning to continue to entangle with Xie Qin on this topic, shook his head and said, "Let's get back to business, where did you just come from?"

"Ahh Xie Qin was stunned for a moment, by the way, there was still something to do, and hurriedly thought about it.

Then, he looked at Tang Ruoruo with a confused expression.

“...... Where did I just go?" he asked.

When Tang Ruoruo heard this, he immediately rolled his eyes and said, "Okay, I asked you, but you came to ask me again." ”

"I can't remember......," Mr. Sechin said.

"You're too bad, aren't you!" Tang Ruoruo complained dissatisfiedly.

"That's right," Xie Qin nodded, "I admit it's my pit, tell me where I just said!"

“...... You ......" Tang Ruoruo pondered for a while, and said depressedly, "I forgot too!"

"Wow!" exclaimed Sechin, "with your memory, you still talk about me?!"

"I really can't remember!" Tang Ruoruo shouted.

"I really can't remember! you're kidding you!" Xie Qin said dissatisfiedly, "That's why you still talk about me, how can you be qualified to say this!"

"Why am I not qualified to say this!" Tang Ruoruo said dissatisfiedly, "The person who spoke is you!

"I forgot, can't you think about it!" said Sechin.

"You forgot why I was thinking!" Tang Ruoruo exclaimed, "You should remember! I'll talk about you too!"

"Why!" exclaimed Sechin dissatisfied, "under normal circumstances, shouldn't I be the one who asks this!"

"What's that?!" Tang Ruoruo was stunned when he heard this.

"What are you talking about!" exclaimed Sechin dissatisfied, "of course it's the phrase 'Where did I just come from'!"

"Why are you saying this?" Tang Ruoruo shouted.

"Because it's a common routine!" Xie Qin exclaimed dissatisfiedly, "It's often 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 about it', 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!"
