Chapter 343 Narrow Tube Effect
Lin Yangyang was confused by her actions: "Sister Qing, what are you doing?"
Lin Zhiqing didn't answer for a moment. She quickly walked to the table, picked up the water cup on the table, and returned to the wall where she had been.
Then she dipped her hand in a few drops of water and gently sprinkled it on the wall.
Lin Yangyang saw the water drops sliding down the wall and falling onto the floor. She was a little confused and couldn't figure out the purpose of Lin Zhiqing's actions.
Lin Zhiqing knew what was going on and turned to walk towards the other wall.
Seeing this, Lin Yangyang hurriedly followed.
Lin Zhiqing also took a few drops of water and sprinkled them on the wall that Lin Yangyang had just kicked.
Then, Lin Yangyang's eyes suddenly widened.
The water droplets did not fall directly to the floor as they did just now. Instead, they slowly disappeared on the wall while rolling down, apparently seeping in.
If there were no traces of water flow, Lin Yangyang would have thought that the wall had absorbed the water.
Her mouth opened wide. "Sister Qing, what's the principle behind this? Why are the water droplets on the two walls different?"
Lin Zhiqing gripped the teacup tightly. "The water dripping down means that the wall we just touched was solid, while the wall the water seeped into is hollow."
After saying that, she followed suit and walked towards the other two walls.
After the water drop test, Lin Zhiqing determined that the west, north, and south walls of this square secret room were solid, while the east wall was hollow.
The wall on the east side was the one Lin Yangyang had just kicked.
After determining whether walls were hollow or solid, Lin Zhiqing explained to Lin Yangyang his initial method of judgment:
"When you kicked the east wall just now, it made a thud, but the sound was crisper and lasted slightly longer."
"When I first knocked on the wall, the sound was dull and short, which meant it was a solid wall."
"This water drop method is also a way to further prove the difference between hollow walls and solid walls."
Lin Yangyang understood what Lin Zhiqing meant and nodded, but a question followed:
"Why would the Jiang family build a hollow wall here?"
Lin Zhiqing shook his head and said truthfully, "I can't tell for now."
"However, the characteristic of cavity walls is that they are not very soundproof."
Lin Yangyang understood what Lin Zhiqing meant, and her eyes lit up:
"That way, if we call for help towards this place, there's a greater chance someone will hear us?"
Lin Zhiqing nodded: "Theoretically, it is correct."
Lin Yangyang smiled happily and opened her mouth to try it, but Lin Zhiqing covered her mouth:
"Cousin, please wait a moment."
"In theory, what you said is correct, but the problem now is that the people outside are all from the Zhenyuan Marquis Mansion."
"You shout towards here. If we are discovered by the people from Zhenyuan Marquis' Mansion, we still won't be able to get out."
In just a few words, Lin Zhiqing explained the matter clearly.
Lin Yangyang's expression suddenly became a little depressed:
"What you said does make sense. Do we have to wait for Shi'an to come before calling him? But how do we know when he will come?"
"This is one problem. There is another problem. Even if my cousin comes, how can he find this place accurately?" Lin Zhiqing frowned and walked to the table and sat down.
She was thinking, not only about Lin Shian's problem, but also about the problem of the hollow wall.
The architecture in Dasheng was different from that in her previous world. The houses here had to withstand many years of wind and rain, so there was generally no possibility of cutting corners.
Moreover, there is no cement or other materials in this place, and most houses are built with basic materials such as wood, stone, and soil.
This kind of project is time-consuming and difficult.
Most people might be lazy or cut corners and build a hollow wall.
However, the Zhenyuan Marquis's Mansion is a wealthy and powerful place, and there is no need to save even a little bit of materials unless it is done intentionally.
Even if it is a hollow wall, it has a certain hardness. Even Lin Yangyang cannot use brute force to break the wall.
What's more, escaping by forcibly breaking through the wall is not a good idea.
Using this method, let’s not talk about whether they can escape or not. Even if they can, Lin Zhiqing and Lin Yangyang will definitely be seen appearing in the Zhenyuan Marquis Mansion.
Reputation is of no importance to these two people, but the problem is that Lin Zhiqing suspects that the Zhenyuan Marquisate wants to "reconcile" with the Lin family and continue to bind herself with the marriage contract.
Therefore, she was not willing to take that risk unless it was necessary.
Another possibility is that this wall is of no use in the first place, so there is no need to build a solid wall.
This makes sense.
Combining these things, Lin Zhiqing could at least judge that the place where they were was most likely not an independent space.
Apart from the solid wall, there is probably a small space outside the hollow wall that serves as a cover.
For example, she often saw in TV dramas that there might be a door behind a bookshelf, leading to a secret room or somewhere else.
Beyond the hollow wall before them now lay most likely a study or other room.
Thinking of this, Lin Zhiqing couldn't help but start thinking about what the layout of the place they were in was like and how she was going to pass the message to the people outside.
The biggest problem is that she is still not sure of the specific location and layout of the space she is in.
Because she always had doubts about that hollow wall.
Why is only the east wall hollow? In this case, the space they are in now is still independent.
The study or other space outside the east wall alone cannot completely cover their small space.
This is a big problem.
Seeing Lin Zhiqing's frown, Lin Yangyang was also a little worried:
"This shabby place has hollow walls and strange winds. I really don't understand what the Jiang family is trying to do by developing this kind of thing."
etc!
wind!
That’s right, it’s the wind!
Lin Zhiqing's eyes lit up, and she looked at Lin Yangyang: "Cousin, you are really a lucky star."
"Lucky star? I am a lucky star? Although this is a compliment to me, Sister Qing, what are you talking about? Does this have anything to do with the current situation?" Lin Yangyang didn't understand what she meant.
Lin Zhiqing had a smile on his face:
"It really doesn't matter, but what you just said to me does. How could I have forgotten about the wind?"
"Cousin, I didn't ask you in detail just now. Was the gust of wind you mentioned the one you felt shortly before entering this secret room?"
Lin Yangyang thought about it carefully before nodding:
"Yes, it's only a few steps away. I felt it from outside."
After hearing what she said, Lin Zhiqing confirmed his thoughts:
"Cousin, the reason there's wind outside is entirely due to the constriction effect."
