"What do you mean?" Zhao Xuan didn't react.

"That means." Zhang Yuan stretched out his hand, drew a circle, and said, "This place is a natural eight-array diagram. ”

"Can this thing still be natural?" Zhao Xuan was a little incredulous.

Zhang Yuan explained: "What's impossible? These things were originally the products of the ancients who summarized the laws of nature, but they were not invented. ”

"But ......" Zhang Yuan untied the rope tied to his feet, put on his backpack, and said to Zhao Xuan: "This should be semi-artificial and semi-natural." ”

Zhang Yuan beckoned Zhao Xuan to go out. As he walked, he said: "Two caves, one leading to the sky and one to the earth, I don't know if the one down is artificial, but the one up to the sky must have an artificial component." Natural caves don't have this trend. ”

Zhao Xuan was not very clear about the geographical content, so he had to echo Zhang Yuan and said: "That means that the seniors of your old Zhang family have built a gossip array here?" ”

"It's national!" Zhang Yuan first corrected Zhao Xuan's statement, and then said: "I made a mistake with my uncle before, when they went to Taiwan, they didn't have time to bring it at all, and they definitely didn't know where this gossip array was!" ”

Walking out of the influence of the gossip array, Zhang Yuan muttered "developed" while calling the institute and asking Song Shaozhen to arrange for researchers to come over for research.

After making the call, Zhang Yuan said to Zhao Xuan: "In recent years, there has not been a single mention of the gossip array in the literature of Longhu Mountain, and Zhang Tianshi probably doesn't know either. ”

Zhang Yuan patted Zhao Xuan's shoulder excitedly and said: "I calculated, the positions of the three gates of opening, birth, and rest, add up to an estimated width of seven or eight meters, and this diameter of fifty or sixty meters is a circle, you can go the right way, Fuxing!" ”

Zhao Xuan was a little puzzled: "But this is only one or two hundred meters in total, right?" Just keep trying, and there will always be a day when you try it? ”

"If you use the results to work backwards, that's right." Zhang Yuan replied, "But even I was determined that this was a gossip array after seeing the two caves. Who knew where the Eye of the Array was? These three gates have changed with the times. ”

Zhao Xuan thought about it, it was indeed the case. It can only be attributed to his luck.

Zhang Yuan held the torn gossip map in his hand, compared it carefully, looked at the time again, walked around the cliff for a small half circle, and then pointed to the direction of the cliff and said to Zhao Xuan: "Probably this is the position." ”

"Just walk in?" Zhao Xuan wasn't sure.

"Or else?" Zhang Yuan took out two headlamps from his bag, handed one to Zhao Xuan, and the other took it on his head. Then he raised his hands flat, compared with the front, and said, "It's about four or five meters wide, just go straight to the direction of the cave, you follow me." ”

Zhao Xuan tried the headlamp, put it on his head, and nodded at Zhang Yuan to indicate that it was okay.

Zhang Yuan tightened the backpack behind his back, waved his hand, and walked forward.

Zhao Xuan hurriedly followed. Entering from this position felt the same as entering from other locations, except that you could faintly see the cave not far away from the woods and weeds.

The two of them walked straight in the direction of the cave, one after the other. When he was about to reach the cave, Zhang Yuan stopped.

still took out the nylon rope from the bag, counted five or six meters, threw the thread to Zhao Xuan, and didn't cut the rest, just tied it around his waist twice, and stuffed the excess back into the bag.

Then he turned on the headlamp on his head, took out his phone again, and tuned up a little music. Turned his head and said to Zhao Xuan: "When you enter the cave, go directly inside, don't stop, there is about a hundred meters, and you can get out of the area of influence of the abnormality." ”

Zhao Xuan followed Zhang Yuan's example, tied the rope around his waist, turned on his headlamp, and said to Zhang Yuan that he was ready.

Zhang Yuan quickened his pace slightly, and just went into the hole without looking back.

The cave is exactly the same as the last time Zhao Xuan came, except that the brightness of the headlamp is much higher than that of the mobile phone, and Zhao Xuan can see the surroundings clearly.

"This is indeed repaired." Zhao Xuan looked at the ground and found that some stones that were too high had been artificially broken, and there were traces of gravel laying between the cracks of the stones. It's just that it looks like no one has walked for a long time.

"I feel like I've been building this place for a thousand years." Zhang Yuan was also looking around as he walked, and the light of his headlamp swayed up and down with him. Zhang Yuan pulled the rope on his waist to prevent it from falling, and then said: "Pay attention to see if there is a fork in the road, be careful not to get lost, and pay attention to listening to music." ”

When Zhao Xuan heard Zhang Yuan say this, he no longer looked at the ground, but turned his head left and right, paying attention to whether there were any forks in the road on the stone walls on both sides.

This time there were no problems, and I didn't find a fork in the road. Zhao Xuan felt that he had only walked for two or three minutes, and Zhang Yuan stopped in front of him.

"Almost." Zhang Yuan took out his mobile phone, turned off the music, glanced at the time again, and said to Zhao Xuan: "This time it's more than five minutes to come." It should still be affected, but not so much. ”

"Go on?" Zhao Xuan asked.

"Wait." Zhang Yuan put down the bag, rummaged through it for a while, and then took out a roll of fishing line from it, looked around, found a large stone with edges and corners, and wrapped the fishing line around the stone a few times and tied it tightly.

Holding the plastic plate and shaking it at Zhao Xuan, he said: "I bought two rolls of 500 meters of wear-resistant line, which should be enough." Cave exploration, I haven't tried it either, I'm afraid of death. ”

"Is this thing useful? Don't you claim to have traveled all over the country? Isn't it a shame to have never drilled a cave? Zhao Xuan sneered, he had never entered the cave, he was still counting on Zhang Yuan, and he didn't know if Zhang Yuan's method was useful.

"Okay, master, I am known as 'Chengxiang Little Heavenly Master in distress'!" Zhang Yuan hung the fishing line on the backpack, picked up the backpack again, and said, "You go forward, don't get entangled in the fishing line." ”

"What a ghost! Can you use dim sum for your name? Zhao Xuan complained, turned around and walked forward.

"Dim Sum? What dim sum? Zhang Yuan obviously didn't want to reply.

The two walked for another hour, and encountered several forks in the road on the way, but fortunately the forks were relatively short, and the two found that it was a dead end and retreated along the fishing line.

Along the way, there are fewer and fewer traces of artificiality, and the road becomes difficult to walk, and many places require both hands and feet to pass.

It wasn't until the second coil of fishing line on Zhang Yuan's back had been released for a small time that they walked into a rock hall, but the two couldn't find a way to continue.

Zhao Xuan crossed his waist, looked around with his headlamp, and asked Zhang Yuan: "Wrong?" ”

Calculating the distance, it should have been six or seven hundred meters in the cave, and the depth should be twenty or thirty meters. The temperature inside the cave was much cooler than outside, and the two of them had already put on their coats on the road.

"Probably not, we've tried all the forks in the road." Zhang Yuan was also looking around.

The cave is not big, it is half a basketball court, the height is less than three meters, it is full of large and small stalactites, in the middle is a spring, the size of a round table, there are many stalactites hanging down above the spring, occasionally there are water drops falling in the spring water, and there is a crisp "ticking" sound. The two of them had already walked around the cave, up and down, but they didn't find a way to go.

"Another anomaly?" Zhao Xuan asked uncertainly.

"You think the anomaly is Chinese cabbage? Everywhere? Zhang Yuan scolded Zhao Xuan, walked to the spring, put down the bag, took out two bottles of mineral water from the bag, handed one to Zhao Xuan, opened one bottle himself, took a sip, and said: "The gossip array at the door, it is estimated that there are few places in the country, and there is also one in the cave?" ”

Zhao Xuan also took a sip of water and said, "Then look for it." ”

"Take a break." Zhang Yuan took out a lantern-style camping lamp from his bag, turned it on and put it on the ground.

The camping lamp is much brighter than the headlamp, and the entire rock hall is fully illuminated, and the rock wall more than ten meters away can also be seen.

It's just that the battery life is much shorter than the headlamp, and it hasn't been taken out before.

"I suspect there's a secret door in the stone wall. Otherwise......" Zhang Yuan raised his hand to turn off the headlamp, found a relatively flat place, and sat on the ground. He stretched out his hand and pointed to the spring in front of him, and said, "Only in this." ”

"Did you bring the salvage equipment?" Zhao Xuan leaned to the spring and looked down with his headlamp. The water looks clear, but the light is still too dim for you to see anything in the water.

Zhang Yuan took out the biscuits from his bag and ate them with Zhao Xuan, and said inarticulate while eating: "No, but it is unlikely to be underwater, the equipment of the ancient people is much worse than ours, and it is not easy to hide things in the water and make them waterproof." Let's check to see if there is a dark room. ”

Zhao Xuan casually ate a few bites of biscuits, and he didn't feel tired, so he got up again and went around to check.

I carefully looked for a small half circle, and I didn't see any artificial traces, there are some cracks between the stone walls, but it can be clearly seen that they are naturally formed, not like they can be opened.

The two of them searched carefully and carefully, but they didn't find anything suspicious. I had to turn back to the spring.

Zhang Yuan pointed to the spring water in front of him: "Come on, it's really inside." ”

"Do you think there will be a mechanism that opens a door with a pull like a handle?"

"Watching too many movies? Imagination so rich? You say that there is such an organ, what does it rely on to supply energy? How to maintain it for thousands of years? ”

"Am I not just talking about it? Just like this one. Zhao Xuan stood next to a stalactite, and as he spoke, he took a picture of the side, there happened to be a waist-high stalagmite, just to signal Zhang Yuan's movements. He raised his hand and pushed forward.

Without much force, the stalagmite tilted to one side, but did not fall.

"This ......" Zhao Xuan looked at Zhang Yuan speechlessly: "It's still ...... Really? ”

"Isn't it?" When Zhang Yuan saw it, he also leaned over, looked at the stalagmites crooked to the side, and said uncertainly: "This is the fall, right?" Otherwise, it's too much of a coincidence? ”

Before Zhang Yuan finished speaking, he heard the sound of "gurgling" from the spring.

The two turned their heads to look at the spring, and two headlamps shone on the water. I saw that the small spring water seemed to be boiling, and bubbles of all sizes kept gushing up.

"It's really a ......," the two looked at each other.

After a while, the boiling at the spring stopped, and only a dull "boom" could be faintly heard.

Zhang Yuan listened sideways for a few seconds, then grabbed the camping lamp on the ground and stuffed it into Zhao Xuan's arms.

grabbed his backpack again, and didn't care about the mineral water biscuits on the ground, just pulled Zhao Xuan to trot outside the cave.

"I believe in your wickedness!" Zhang Yuan shouted at Zhao Xuan as he ran: "it, this is a geyser!" If the spring is too big, we'll both die here! ”
