Looking at the water that kept dripping, Hua Xinyu felt that maybe she was like this water droplet, from the formation to the fall to the ground, short and ordinary.

When everyone feels that they are on the road to death, they often have important memory fragments projected in their minds, and Hua Xinyu is no different.

She filtered through everything she remembered, and she found that her past was really too dull, and there was nothing brilliant about it.

If she is really trapped in this tunnel, then her life will be really a pity, thinking about it, her eyes once again appeared in front of her eyes full of sunny smile, every time she encounters difficulties, Manqingyun will always appear in her mind, it seems that Manqingyun is her belief, can take her out of a desperate situation, the smile that comes to mind seems to encourage her not to give up anything easily.

Yes, you can't give up, as long as there is a glimmer of hope, you have to catch it!

Hua Xinyu regained her spirit and observed the environment of the tunnel again.

But in Hua Xinyu's eyes, this dim tunnel was like a passage to hell, and the thick aura of death enveloped the two of them, if it weren't for the occasional sound of underground animals moving, both of them really thought that this was a Jedi.

However, the sound of this underground animal walking in this environment is also a little terrifying, which makes people feel uneasy.

The water was dripping on the ground, as if with a certain rhythm, making a splash, and Hua Xinyu was attracted by the sound of water droplets, and once again focused her attention on the place where the water was dripping.

She looked up at the top of the passage, and saw that a thick layer of moss had accumulated in the area, hanging upside down from the top to form a cone-like shape, and water was dripping from the tip of the cone-like cone to the ground.

Hua Xinyu looked at the water droplets and fell into thought.

How can there be water dripping here?

Although they walked in from the edge of the waterhole, and it was very humid here, it was not to the point of constant dripping, and this level of dripping water means that there must be plenty of water at the top, right......

Hua Xinyu hesitated for a moment, and then said to Lin Qing: "Do you think we will go to the bottom of the waterhole, or go under the underground river, the passage we are walking is not horizontal, but has been going down?" ”

"How?" Lin Qing asked curiously.

Hua Xinyu pointed to the place where the water dripped from the top of the passage.

"Look at that water droplet, it drips down so densely, it means that there must be a water source on it, you remember where we came in."

"That waterhole ......"

Lin Qing's brain spun extremely fast, and he immediately understood what Hua Xinyu said.

The place where they came in was a big space, although it was pitch black, but they knew that there was a waterhole there, and that waterhole was very deep, because they fell from the altar of Changsheng Village into the waterhole, and they didn't sink to the bottom when they fell from such a high place, and Lin Qing could feel a lot of buoyancy when he fell into the water, if he hadn't fallen down with Hua Xinyu in his arms, it was estimated that he would not have been able to find Hua Xinyu and save Hua Xinyu to the shore.

After listening to Hua Xinyu's words, Lin Qing understood, that is to say, the place where they came in was above the water level, if the place they were in now was also above the water level, it would be impossible to form such a rapid dripping phenomenon.

There are two reasons for this, one is that it is not the rainy season at all, and the other is that the walls of the tunnel are made of marble, and the inlaid joints of the marble have obviously been treated with special materials, and the effect is to be used for waterproofing, although the tunnel is a little old, but if there is no large amount of water in the soil layer, it is impossible to form such a rapid dripping phenomenon.

"You mean to say that the tunnel is not flat, but going down, and we're going down? But why can we go back to where we are? Lin Qing shook his head, frowned and said, "No, no!" ”

Listening to Lin Qing's words, Hua Xinyu also felt that her inference was a bit problematic, and she frowned again and thought about it.

Just as Hua Xinyu was thinking, Lin Qing spoke.

"I see." Lin Qing suddenly understood, he raised his head, looked at Hua Xinyu, and said: "Our current position is indeed under an underground river or a waterhole, but we haven't been going down, from a spatial explanation, that is, if we look down from this place, the trajectory of the tunnel is a circle, and this circle is docked end to end, so we can walk back to the same place, but if we look at it from the side, then what we see is a horizontal line." S' shaped trajectory, so we don't go all the way down, sometimes we go down, sometimes we go up again, so everything makes sense. ”

Hua Xinyu simulated the trajectory of the tunnel in her mind according to Lin Qing's words, and found that what Lin Qing said was indeed very consistent with the information they could know so far.

"We know the shape of the tunnel, but how do we find our way out?"

The problem to be considered is back to square one, and only when a way out is found can the problem be truly solved.

Lin Qing groaned: "Although part of the function of this tunnel may be used to trap people, but no one should be bored enough to spend so much manpower and material resources to build such a large underground project just to build a tunnel that is only used to trap people, this tunnel will definitely have other uses, maybe there are some unknown secrets hidden in this tunnel." ”

"What's the secret?" Hua Xinyu asked subconsciously, but after asking, she felt a little stupid, Lin Qing had never been here, how could she know.

Lin Qing glanced at Hua Xinyu, and this time he did not ridicule Hua Xinyu, but continued: "Maybe there is an incomparably precious treasure hidden here, or rather, this is really an ancient tomb, if this is the case, there will definitely be other places to go out here, let's imagine that since there is a way out here, the way out will definitely not appear in a damp place, because if the space is created underground, the more humid the place, the greater the amount of work, and it is extremely unstable, which is easy to cause a collapse accident, So we can look for a way out from a drier place. ”

"At present, we can only do this, then let's find it quickly, and if we stay longer, it is estimated that our spirit will only get weaker and weaker." As she spoke, Hua Xinyu stood up and walked towards the drier place ahead.

Lin Qing also stood up, and went to find a drier place with Hua Xinyu, and after walking for more than twenty minutes in a row, they stopped, because they had already felt that this place was very dry, it should be the driest place in this passage, and every time they took a step, there was dust on the ground.

The two of them coughed repeatedly at the smell of rotten dust, then covered their mouths and noses with one hand, and waved the dust in front of them with the other, trying to let as little dust as possible into their mouths and noses.

The two waited until the dust gradually decreased, and then walked lightly to the edge of the passage again and observed the walls of the tunnel, but to their regret, they found that the walls here were almost exactly the same as before, and after careful observation for half an hour, the two looked at each other, and then shook their heads helplessly.

Still no exit has been found.

Under the toss, Hua Xinyu was so tired that she sat on the ground against the wall, a burst of dust kicked up, and then she screamed in pain.

"Oops! Something, my ass. ”

As she spoke, she inhaled a large amount of dust, and she coughed and touched her ass in pain.

Hua Xinyu hurriedly moved to the side and kept rubbing her buttocks, but just as she was kneading, the wall she was leaning against suddenly moved.

There was a strange sound, and then dust drifted up.

Hua Xinyu was so frightened by this sudden vibration that she couldn't even bother to rub her buttocks, jumped up directly, and shouted, "Ah, what! ”

But after she finished shouting, the surroundings fell silent again.

Lin Qing was a little confused by Hua Xinyu's startled behavior, and he asked, "What's the matter?" ”

"This ...... This wall...... It moved. Hua Xinyu has a little knotted tongue when she speaks, she is a girl, in this dimly lit place, and there are haunted legends, it is impossible to say that she is not afraid, the moment the wall moved just now, her cold hair exploded all of a sudden, and a chill spread from the back of her head to the soles of her feet, making her goosebumps all over.

Until now, she was still a little frightened, but after Lin Qing heard what Hua Xinyu said, not only did she feel scared, but she also had a very surprised expression.

He asked again, "What you said is true, is this wall really moving?" ”

"yes, I'm sure, I'm pretty sure it actually moved."

After Hua Xinyu finished speaking, she took a step back, as if the wall would suddenly pounce and bite people, but it was so weird here, she even felt that this was a very likely thing.

Unlike Hua Xinyu's nervousness, Lin Qing quickly approached the wall that Hua Xinyu was leaning against just now with joy on his face.

"Be careful." Hua Xinyu reminded in the back.

Lin Qing's hand reached into the wall again, and observed the wall again, after observing for a while, he found that except for a little less dust, there seemed to be no change, he pressed all the places on the wall, especially the place where Hua Xinyu leaned, he pressed it a few times, but still found nothing.

He thought for a while, recalled what Hua Xinyu said just now, and suddenly he came to his senses: Ass, by the way, it's ass!

He's always focused on the wall, but who's to say that the switch to open the exit on the wall has to be on the wall?

He looked down, and sure enough, there was a slightly raised place directly below, if you didn't look carefully, you couldn't see it at all, he quickly brushed away the dust from that place, and a hexagonal black metal block with a slight bulge in the middle appeared in front of his eyes.
