Zhao Xuan stood on the edge of the cave, holding a headlamp in his hand, helping Zhang Yuan illuminate the surroundings.

But after a little bit down, I couldn't see it.

"What's going on down there?" Zhao Xuan asked on the walkie-talkie.

"It's okay, it's narrower." Zhang Yuan said as he heard the sound of squirming, which should be crawling.

"Then be careful." Zhao Xuan saw that there was no problem, so he sat next to the entrance of the cave and waited slowly, while paying attention to the movements around him.

Although Chen Daochang said that this spring water will not gush several times a year, it is still necessary to be careful.

"Wipe ......" Zhang Yuan shouted on the walkie-talkie, and he swallowed the back half of it again.

"What's wrong?" When Zhao Xuan heard the shout, he hurriedly stood up, looked down at the entrance of the cave with his head up, and asked Zhang Yuan, "Are you okay?" ”

Zhang Yuan's breathing and crawling sound could still be heard on the walkie-talkie, so he shouldn't be in such a hurry.

After a while, Zhang Yuan said, "It's okay, if you meet a few baby fish, you can come down too." ”

While saying that, Zhao Xuan saw a flickering light coming from the cave.

"Just throw the bag down, it's not high."

Zhao Xuan grabbed the bag, lay on the ground, stretched out his hand to put the bag down, and saw Zhang Yuan stretch out his hand to take the bag away, and waved at Zhao Xuan to signal him to go down.

Zhao Xuan grabbed the rope and walked down the groove, the stone wall was a little slippery, not very easy to settle, and a small half of the weight was pressed on the rope.

However, the distance from straight up and down is not long, only three or four meters, and it will go down to the bottom after a while.

Standing on the ground, Zhao Xuan saw a horizontal hole at his feet. Less than a meter high, you can only climb in.

Zhang Yuan was facing inward, the backpack was behind him, he was turning his head to look at Zhao Xuan, and seeing that Zhao Xuan had also climbed inward, he continued to crawl forward, climbed two steps and dragged the backpack behind him.

Zhao Xuan asked while helping to push the backpack, "Isn't there a baby fish in front?" Still in the past? ”

"I see the way." Zhang Yuan didn't look back, and said as he crawled: "Just don't talk later, cave creatures are not sensitive to light." ”

After climbing a short distance, the cave gradually widened, and after another seven or eight meters, the two of them were able to stand up straight.

Zhang Yuan put the backpack back on his back, turned his head, made a "shhh" gesture at Zhao Xuan, and walked forward.

Not long away, Zhao Xuan heard a sound not far away.

Further on, I entered a hall-like place, probably because I was underwater most of the time, but there were not so many stalactites.

Half of the left hand side was water, and I don't know how deep, and the two of them just walked along the water's edge.

The sound of water became louder and louder, Zhao Xuan listened to Zhang Yuan's words, couldn't help but make no sound, but turned his head away.

At least dozens of baby fish, I don't know if they are fighting or fighting, churning countless waves not far away.

Roughly estimated, each one is at least as big as the one Zhao Xuan encountered yesterday.

Zhao Xuan couldn't hold back the thought of looking again, turned his head and continued to walk forward.

Turning a hole, it was far away from the water, and the sound of the water gradually became smaller, Zhang Yuan turned his head and said to Zhao Xuan: "Okay, it should be fine." ”

"How many do you call that? Math taught by PE teachers? Zhao Xuan couldn't help but complain.

"More than two is how many, is there a problem?" Zhang Yuan said as he walked: "Biologists are here to be euthanized. ”

After Zhao Xuan met the baby fish yesterday, he went back at night to check a lot of information about the baby fish, this creature almost all live alone, and it is rare to hear of such a large group.

couldn't help but ask Zhang Yuan: "How can there be so many?" ”

"Who knows." Zhang Yuan spread his hands with his back to Zhao Xuan, and said, "Grab the land, what else are the creatures?" ”

"A picture should be taken." Only then did Zhao Xuan remember: "This should belong to precious information, right?" ”

"We are exploring the way, and professional things are left to professional people." Zhang Yuan dispelled Zhao Xuan's thoughts.

While talking, the two walked out for dozens of meters, and a bluestone staircase appeared in front of them, and when they looked up along the stairs, a stone house was at the end of the stairs.

"That's it." Zhang Yuan took out the camping lamp from his backpack, and said excitedly while turning it on: "I guess this is the so-called 'secret storage'." ”

The two walked up the steps, the steps were not long, only dozens of steps, two stories high.

There was a small platform in front of the stone house, and Zhao Xuan stood in front of the house, looking at it by the light of the camping lamp.

It is said to be a stone house, but in fact, it is only half extended by the position of the depression of the mountain behind it.

The stone houses have no windows and are built with bluestone strips that are more than one meter long.

The door was a single stone slab, with only a pit in the place of the handle, which should have been an iron handle, which was now rusted.

Zhao Xuan walked to the door, picked the crack of the door and tried it, but he couldn't open it. Turning his head and asking Zhang Yuan, "Is there a way?" ”

"How easy it is." Zhang Yuan said, put down the bag, took out a Swiss army knife and a pen, looked for a long time, and patted his head: "The rope is still in the spring." ”

Zhang Yuan had to remove the heel laces from his shoes, tie them in the middle of the saber, pick out the screwdriver on the saber, dig out the hole in the handle, and then pull the rope, stuff the saber into the hole, and stab the saber in.

When he was sure that the saber had fallen into the door, he pulled the laces and found that they were tightened, so he wrapped the laces around his hand and pulled them back.

Although the gate is made of stone, the workmanship is obviously very good, it is not as laborious as expected, and it does not make any sound.

Gradually, a crack in the door was revealed, and this time there was no need to pull the shoelaces, Zhao Xuan reached in and helped pull it from the inside out.

The door opened a large class, and he heard a "click" from the position of the door shaft, and before Zhao Xuan could react, Zhang Yuan next to him shouted: "Lie down!" ”

Zhao Xuan has also been training for nearly a month, and the response to these basic things is not slow, Zhang Yuan's voice has not fallen, Zhao Xuan has not thought about it, and he has already fallen on the ground.

As soon as Zhao Xuan lay down, he heard the sound of "Zheng", "Zheng", "Zheng".

After a while, there was no more voice, and Zhang Yuan spoke: "Get up, it's okay." ”

Zhao Xuan got up on the ground while asking Zhang Yuan, "What is it?" ”

"There's a hidden weapon."

"Where? Nothing just to hear the sound? Zhao Xuan looked around, but didn't see any hidden weapons flying out.

"It's rotten." Zhang Yuan continued to open the stone door completely, then turned around, pointed his headlamp at the wall facing the door, and pointed to the small hole in the wall: "Those, do you see it?" ”

Zhao Xuan looked at the wall and saw that there were more than ten thumb-thick holes in the high and low. He turned his head and asked Zhang Yuan: "What are we doing when it's rotten?" ”

"Do you dare bet?" Zhang Yuan sneered: "I'm ninety percent sure that this thing is rotten, but do you want to bet on the remaining 10%?" ”

"That's right." Zhao Xuan nodded, and asked again, "Then why is there still a voice?" ”

Zhang Yuan pulled the Swiss Army knife and shoelaces out of the stone door, untied the shoelaces, sat directly on the ground, and put the shoelaces back on. Give Zhao Xuan half of the explanation and half of the class.

Half of the ancient crossbow string was made of cow tendon, silk, cotton, linen, etc., and it was preserved for a relatively longer time than arrows made of wood, iron, and bird feathers.

Zhang Yuan speculated that this set of mechanisms was estimated to be made of stone except for crossbows and arrows, otherwise it would not have been possible to keep them working for so long.

"You know that, too?" Zhao Xuan asked in surprise: "It's really Captain Jin, you." ”

"Touch your sister's gold!" Zhang Yuan scolded: "Touching gold will cut off children and grandchildren!" ”

"You can't find a girlfriend anyway."

"Get out, sir, I just don't want to look for it."

"It's not difficult to find the paper man's wife."

Now that they had arrived at the place and confirmed that there was no danger, the two relaxed and entered the stone house while arguing.

Putting the camping lamp on the ground, Zhao Xuan looked around, the stone house was not big, only about twenty square meters.

There are more than a dozen wooden boxes on the left and right sides against the wall, and I don't know how long they have been there, but they are all rotten, and the wood fragments and the contents are scattered all over the ground.

"There's a hole in this!" Zhao Xuan found a big hole in the corner of the wall on the left hand side of the door, and took a headlamp to shine it, but he couldn't see how deep it was.

Looking to the other side, there was an identical hole in the right corner, and said, "There is also this side." ”

Zhang Yuan walked to the right corner and also learned from Zhao Xuan to take a headlamp and take a photo. Let out a "Huh? ”

He said to Zhao Xuan again: "Turn off the lights, there seems to be light here." ”

Zhao Xuan turned off the camping lights and turned off the headlights.

Zhang Yuan also turned off the headlights, and suddenly the entire stone house was dark. Zhao Xuan was about to ask, but Zhang Yuan said again: "Don't speak!" ”

Zhao Xuan closed his mouth.

"That's it." After more than ten seconds, Zhang Yuan turned on his headlamp and said to Zhao Xuan: "Uncle, we are directly below Sanqingguan!" ”

"Huh?" Zhao Xuan didn't react.

Zhang Yuan pointed to the entrance of the cave: "This hole is just leading to the well, and I can hear people outside." ”

"Really? Such a coincidence? Zhao Xuan reacted and asked, "Was it designed at that time?" Is it so strong? ”

"I guess it's a coincidence, such a precise positioning technology doesn't seem to be planned." Zhang Yuan shook his head.

Zhao Xuan walked up to Zhang Yuan and pointed to the hole on the ground: "Then what is this hole for?" ”

"It's supposed to be drainage, and I should have noticed that this place would occasionally be flooded to speed up drainage." Zhang Yuan shone his headlamp at the wooden box and said, "Look, there are cowhide and oiled paper in the box, and it should be prepared for waterproofing." ”

Zhao Xuan also swept around with a headlamp, and didn't see much where the cowhide was, where the oiled paper, and where the things in the box.

"How was this hole dug?" Zhao Xuan took a lamp to shine on the two holes and asked Zhang Yuan: "Such a small hole is dug by manpower?" ”

"You underestimate the technology of the ancients, if there is an electric drill in modern times, there is no human drill?" Zhang Yuan chuckled lightly and said: "The ancient technology is poor, the main thing is the accuracy, many things you thought appeared very late, but they were actually available very early. ”

Zhang Yuan said as he looked around with his headlamp.

"Holy!" Zhang Yuan took a lamp and shone it on a wooden box and said, "I know what is going on with this well water!" ”

"What are you doing!" Zhao Xuan was taken aback: "I was shocked when I spoke." ”

"I said, I know what's going on with the well water." Zhang Yuan said: "It's a ghost, I'll just say, how can there be so many abnormalities." ”

"There's an abnormality in the well water, isn't that what you said?" Zhao Xuan said innocently: "Rely on me? ”

"Don't blame anyone. You've only been here for a month, how many anomalies have you had? ”

"What the hell is going on?"

"This." Zhang Yuan shook his headlamp and said, "This special meow is a box of pills." ”
