Chapter 125: That wall is moving!

Watching the dripping water, Huaxinyu felt that maybe she was like this water drop, short-lived and ordinary from formation to falling to the ground.
When everyone feels they are walking towards death, they often see important memories flashing in their minds, just like what Hua Xinyu experienced.
She sifted through all the things she remembered and realized her past was really ordinary with no remarkable moments.
If she really got trapped and died in this tunnel, it would be such a pity for her life. As she thought about it, the bright smile of Man Qingyun with full of sunshine emerged in her mind again. Every time she encountered difficulties, Man Qingyun would always appear in her mind. It seemed that Man Qingyun was her belief that could lead her out of dire situations. The smile in her mind seemed to encourage her not to easily give up on anything.
Yes, we cannot give up, we must seize any glimmer of hope!
Flower Xinyu lifted her spirits again and observed the surroundings of the tunnel once more.
However, in Flower Xinyu's eyes, this dim tunnel was like a passage to hell, with a strong smell of death enveloping the two of them. If it weren't for the occasional sound of underground animals moving, the two of them would really have thought that this was a dead end.
However, the sound of these underground creatures moving in this environment is also somewhat terrifying, making people feel uneasy.
The sound of water dripping on the ground, like a certain rhythm, splashes out water flowers. The fragrance of the flowers is attracted by the sound of the dripping water and once again puts attention on the area where the water is dripping down.
She lifted her head and gazed up at the top of the passage, where a thick layer of moss had accumulated, hanging down in a cone-like shape and constantly dripping water onto the ground from the tip of the moss cone.
Hua Xinyu looked at the dripping water and began to think.
Why are there drops of water here?
Although they had walked in from the edge of the pond and it was quite humid, it shouldn't be dripping like this. This kind of consistent dripping means there must be a sufficient source of water at the top. Could it be...?
Hua Xinyu hesitated for a moment before saying to Lin Qing, "Do you think we might have walked to the bottom of the pool or even under the underground river? The pathway we're taking isn't horizontal, it's been going downwards all the way."
"What are you saying?" Lin Qing asked curiously.
Hua Xinyu pointed to the place where the water was dripping from the top of the passage.
"You see those drops of water, they are falling so densely, which means there must be a water source above, do you remember where we came in?"
"That pool..."
Lin Qing's mind worked very quickly and he immediately understood what Hua Xinyu was saying.
Where they came in was a very large space, although it was pitch black there, they knew there was a pool, and that pool was very deep. They fell into that pool from the altar in Changsheng Village. They didn't sink to the bottom even after falling from such a high place, and Lin Qing could feel a strong buoyancy when he fell into the water. If he had not been holding Hua Xinyu when they fell, he probably would not have been able to find her and save her to the shore.
After hearing what Huaxinyu said, Lin Qing realized that the place they entered was above the horizontal plane. If the place they were in now was also above the horizontal plane, it would be impossible for such a rapid dripping phenomenon to occur.
The reason for this phenomenon can be attributed to two factors. Firstly, it is not currently the rainy season. Secondly, the walls of the tunnel are made of marble and the gaps between the marble tiles have been specially treated with waterproof materials. Although the tunnel is a bit old, if there is not a large amount of water in the soil, it is impossible for such a rapid dripping phenomenon to occur.
"So you're saying that this tunnel isn't flat, it's going downward and we've been going down all along? But then how come we can get back to where we started?" Lin Qing shook her head and furrowed her brows, saying, "No, no, something's not right!"
After listening to Lin Qing's words, Hua Xinyu also felt that her inference was a bit problematic, and she frowned again and started thinking.
Just as Hua Xinyu was thinking, Lin Qing spoke up.
"I see." Lin Qing suddenly understood and looked at Hua Xinyu, saying, "Our current location is indeed under an underground river or pool, but we are not always going downward. From a spatial perspective, if we look down from here, the trajectory of the tunnel is a circle that connects at the beginning and end, so we can walk back to the original spot. However, if we look at it from the side, what we see is a horizontal 'S'-shaped trajectory. That means we are not always going down, but sometimes we go down and then up again. That's how everything makes sense."
Hua Xinyin simulated the trajectory of the tunnel in her mind based on Lin Qing's words and found that what Lin Qing said was very consistent with the information they currently knew.
"Although we know the shape of the tunnel, how can we find the way out?"
The question to consider has come back full circle, and only finding a way out can truly solve the problem.
Lin Qing pondered and said, "Although this tunnel may have been partially constructed to trap people, no one would be so bored as to spend so much manpower and resources just to build a tunnel solely for trapping. This tunnel must have other uses, perhaps there are some unknown secrets hidden within."
"What secret?" Hua Xinyu asked subconsciously, but after she asked, she felt a bit silly. Lin Qing has never been down here, so how could he know?
Lin Qing glanced at Hua Xinyu, this time not teasing her, but continued, "Perhaps there is a very precious treasure hidden here, or perhaps this is really a tomb. If so, there must be other ways out here. Let's think about it. Since there is an exit here, it definitely won't be in a damp place. Because creating space underground in wet areas requires a larger construction volume and is extremely unstable, it can easily cause collapse accidents. Therefore, we can look for the mechanism to open the way out from a relatively dry place."
"Currently, this is the only thing we can do. Let's hurry and search. If we stay here any longer, our energy and spirit will only weaken." said Hua Xinyu as she stood up and walked towards a drier area ahead.
Lin Qing also stood up and went with Hua Xinyu to find a drier place. After walking continuously for more than 20 minutes, they stopped because they had already felt that this place was very dry, probably the driest place in this passage. Every step they took, dust was lifted from the ground.
Both of them smelled the musty smell of dust and coughed continuously. Then, one hand covered their mouth and nose, and the other hand waved the dust in front of them, trying to prevent less dust from entering their nose and mouth.
After waiting for the dust to slowly settle, the two of them walked cautiously along the edge of the tunnel and observed the walls. Unfortunately, they found that the walls here were almost identical to the previous ones. After carefully observing for half an hour, the two of them looked at each other and shook their heads helplessly.
还是没有找到什么出口。
一顿折腾之下，花馨雨累得一屁股坐在了靠墙的地面上，一阵灰尘扬起，随后就传来了她的一声痛呼。
"Oh! What is this? My butt."
During her speech, she inhaled a lot of dust and coughed painfully while rubbing her butt.
Hua Xinyin quickly moved aside and rubbed her butt continuously. However, while she was rubbing it, the wall she was leaning on suddenly moved a little.
There was a strange sound, followed by dust swirling around.
Hua Xinyu was frightened by the sudden vibration and jumped up, shouting, "Ah, what's that!"
But after she had shouted, everything went quiet around.
Lin Qing was a bit confused by Hua Xinyu's sudden behavior and asked, "What's going on?"
"This...this wall...it moved," said Huaxinyu, her tongue tied in knots. As a girl, it was impossible for her not to be afraid in such dim light and a place with haunted legends. When the wall moved just now, a chill ran down her spine and made all the hair on her body stand on end.
Until now, she is still a little bit shaken, but after hearing what Hua Xinyu said, Lin Qing not only didn't feel scared, but also had a very surprised expression.
He asked again, "Are you telling the truth? Did the wall really move?"
"Yes, I'm sure, very sure that it just moved a little bit a moment ago."
After saying that, Huaxinyu took a step back, as if the wall might suddenly jump out and bite her. However, in this eerie place, she felt like that was a possibility.
Unlike the tension on Hua Xinyu's face, Lin Qing had a look of joy as he quickly approached the wall that Hua Xinyu had leaned against just now.
"Be careful," Hua Xinyu reminded him from behind.
Lin Qing reached out to the wall again and observed it carefully. After a while, he found that apart from being slightly less dusty, there seemed to be no change. He pressed every part of the wall, especially the area where Hua Xinyin was leaning, but still found nothing.
He thought for a moment, recalling what Hua Xinyu had just said, and suddenly he realized: butt, right, it's the butt!
He had been focusing on the wall the whole time, but who said that the switch to open the exit on the wall had to be on the wall?
He lowered his head and saw a slightly raised spot directly below. If he hadn't looked carefully, he would have missed it. Quickly brushing away the dust on that spot, a hexagonal, slightly raised black metal block appeared before his eyes.
