He Xie Qin looked up and down the wall, he felt unbelievable, this is too lucky, right?

I originally thought that the method of knocking on the wall to find the dark room was too ridiculous, and I didn't plan to use it!

Xie Qin couldn't believe that such a thing could happen, so he decided to make another confirmation.

Confirm what? Confirm whether this is a dark room or not.

Just as it is not necessarily Tang Seng who rides a white horse, the crisp sound is not necessarily a dark room, but may also be empty.

Anything is possible, such as carelessness when building a house (I don't think it's so careless), for example, there are circuits and electric switches hidden in it (well, this kind of maybe it's more common, probably), and for example...... There was something hidden inside, but it wasn't a dark room, it was ...... Safe or something (this kind of must be very common, definitely!)......

Well, what we need to confirm now is how big the hole is inside, so as to determine whether it is a dark room, a dark grid, or an ordinary hole.

Well, the latter two shouldn't be so easy to judge, right...... Xie Qin said in his heart.

But when he thought about it, it doesn't matter, I don't want to make sure it's the latter two, just make sure it's a dark room inside!

Thinking so, Sechin raised his hand and knocked on the wall, this time, he was a little away from the place he had just knocked.

Knock knock!

Well, it's hollow here too. Xie Qin nodded secretly.

He put a little further distance and knocked on the wall.

Knock knock!

It's still hollow.

I'm testing this hole right now...... Think of it as a length, but now it's time to go all the way to the ends of both sides, and then you'll be able to measure it again...... Width or height.

Thinking so in his heart, Xie Qin was about to find the end of one side first, he separated a little distance, and raised his hand to knock again.

Knock knock!

Spread out a little more.

Knock knock!

Xie Qin simply knocked all the way to the wall and moved to the left.

Knock knock!

Xie Qin immediately stopped, and the change in his voice was obvious, and the dull sound undoubtedly touched a real wall.

Okay, Xie Qinxin said, this is the end of the road, and the next thing to look for is the other side......

He first picked up the bladeless knife and sharpened it with the scabbard to make a mark on the wall, and then he knocked on the wall, knocking as he walked to the right.

- Knock knock knock!

After a while, a dull voice sounded again, telling Sechin that it was not hollow inside.

Okay, now you know the length. Xie Qin nodded secretly and made a mark with the scabbard again.

He looked at the markings on both sides, this length, it was a bit wide for a secret door......

It's definitely not going to be a dark grid, it's a bit too wide for a dark grid, and such a wide dark grid is completely qualified to be a dark room!

However, it can't be confirmed that it is a dark room, and it needs to be confirmed again.

So, now it's time to measure the width.

Xie Qin looked up and down, and the lower level of the wall was blocked by a cabinet.

Well...... Let's measure the table first.

Sechin picked up the bladeless knife and struck the wall continuously with the scabbard, this time moving upwards as he struck, and the man stood still.

Knock Knock Knock Knock......

Knock knock!

Xie Qin raised his eyes and immediately moved the scabbard down.

Knock - knock!

Width, or rather height, is it!

Xie Qin immediately sharpened a mark with the scabbard.

Then he took two steps back and looked at the positions of the three marks as a whole.

The length must be qualified, the height...... Taller than me—provided that the part of the wall that the cabinet blocks is also hollow, the two together must be taller than me.

At this size, it's definitely a secret door that hasn't run away!

No, you should first determine which part of the cabinet is blocked.

Hey, Xie Qin shook his head, thinking to himself, I originally wanted to find the secret door by looking at the color of the paint......

He looked up and down at the paint on the wall, which was no different from the surroundings, and couldn't help but sigh secretly, he really took it for granted, and now that he thinks about it, no one with a little brain will only paint the part of the secret door, because the contrast is so obvious that it can be seen with the naked eye.

So there is no doubt that the people of the Red Fire Hall must have repainted the entire room so that it could be used to hide this dark room.

Sechin looked at the sides and immediately became more sure of his thoughts—the paint was too new.

Judging from the appearance of the house, this house is obviously some years old, and compared to the appearance, no, there is no need to compare with the appearance, this paint is freshly painted, which is too obvious!

The newly painted paint and the old-fashioned house form a strong contrast, and the sense of disobedience is very strong.

This can only be explained as a hidden dark room, Xie Qin thought to himself.

Ah, right.

He thought of another thing.

Those considerations just now started from two details, one is the paint, which is not leaky, and the other is the sound, Xie Qin is through the sound, like a blind cat running into a dead mouse, and hit the secret door.

But there are three details mentioned just now, what about this third detail?

The third detail is the scratches, which can be used to determine whether the secret door is a manual flap door or a mechanical or electric current actuated by the presence or absence of scratches...... That kind of secret door.

Xie Qin looked down.

The floors in this house are all solid wood, although they are not newly paved, but the maintenance is good, and there are no signs of potholes and bumps that are common on old floors.

This is a good thing, which means that the scratches will become extra conspicuous.

If it is a flap door, it will definitely leave scratches on the ground.

That's right!

A thought suddenly popped up in Xie Qin's heart, I may have thought wrongly, this cabinet blocking the wall is probably not used to block the secret door, but to block the scratches on the ground!

Thinking about it like this, Xie Qin suddenly felt that his thinking had become a lot clearer.

Yes, yes, he said to himself, this is too possible!

The more Xie Qin thought about it, the more it made sense, no matter what, it was very necessary for this cabinet to be moved aside.

Sechin stepped forward and walked to the side of the cabinet.

"Brother Lingsheng, what are you going to do here?" Tang Ruoruo asked suspiciously.

"Oh," Xie Qin smiled at her, "I'm going to move this cabinet." ”

"Get out of the way?" Tang Ruoruo was stunned when he heard this.

"That's right. Xie Qin nodded, "I think this cabinet is probably used to hide some traces." ”

“...... Like a secret door?" asked Tang Ruoruo.

“...... Well. Sechin nodded, what he was meant to say was to hide the scratches.

"I'll help you!"

Tang Shuyan immediately said, and he was about to step forward to help.

"Wait, Young Hall Master. Sechin waved his hand.

"What's wrong?" Tang Shuyan asked, "Do you suspect that there is something wrong with this cabinet?"

"Not really. Sechin shook his head.

"Then what are you ......," Tang Shuyan asked puzzled.

"If my guess is correct...... "this cabinet ......" said Sechin.

He took a step to the side, then jerked his left shoulder against the side of the cabinet.

“...... It should be light!"

Before he could finish speaking, the cabinet here suddenly struggled, directly crooked, then tilted, and finally fell directly to the ground.

There was a loud bang.

Seeing this, Xie Qin, Tang Shuyan and Tang Ruoruo were all stunned.

Together with the rest of the people, they were all stunned.

Xie Qin was stunned, because he didn't expect that this cabinet would be so light, and he didn't use much effort to top it, so he would directly overturn it.

It's unbelievable!" Xie Qinxin said.

Everyone was stunned because they didn't expect that this cabinet was really as spicy and light as Xie Qin said.

It's unbelievable!, the hearts of the people said.

"Brother Ringing!" After Tang Ruoruo came back to his senses, he immediately asked, "How did you know that this cabinet is so light?"

"It's just a prop to hide traces, there's no need to make it heavy," Xie Qin responded, "Otherwise, you won't be able to get along with yourself—you think, every time you want to open the secret door, you have to make a lot of effort to move the cabinet first, isn't it hard to get along with yourself?"

When everyone heard this, they all thought that what Xie Qin said was very reasonable.

At this time, Zu Yuji suddenly said, "Look at the ground!"

"On what ground?" Tang Ruoruo asked confusedly.

"Brother Ringing, at your feet!" Zu Yuji said again.

"What's wrong with Brother Lingsheng's feet?" Tang Ruoruo said as he looked to the ground, and then he was stunned for a moment, "This is ......"

Xie Qin glanced down, then smiled slightly.

"As I expected. ”

"Material... What are you expecting?" Tang Ruoruo asked confusedly.

"These scratches. ”

Sechin looked down at the scratches on the ground, a very obvious semi-circular scratch, two semicircles to be exact, and many shapeless scratches in the middle.

"That cabinet is there to hide the scratches. ”

Xie Qin said in a deep voice.

"Huh?" Tang Ruoruo was stunned, "Isn't that cabinet used to cover the secret door?"

"No," Sechin shook his head, "it's for covering up scratches, because they're too obvious." ”

"Well, Brother Ringtone has a point. Zu Yuji agreed, "This kind of mark on the floor is too conspicuous, and it can be seen from a long distance." ”

"If someone sees it, then the existence of the secret door is meaningless. "These scratches are clearly a sign to outsiders that there is something wrong with this place." And through these scratches, you can basically judge why this cat is greasy. ”

"Not bad. Zu Yuji nodded, "People with a little common sense will think that there is a secret door here!"

Ah, no, I don't think the average person has this kind of common sense. Xie Qinxin said, but what Xiaoyu said also made sense, it was indeed too easy to judge.

He took a few steps back.

"Let me see ......"

Xie Qin said, looking down from above, from the mark on the top to the scratches on the ground.
