There are wide and narrow places in the underground channels, so there are various different styles underground. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The variety and strange shapes of the landform are rare on the surface. The bamboo shoots and barbs of the stalactite region are spectacular, and people are like being in the midst of the giant fangs of monsters. In some special places, the torch shines and reflects the psychedelic brilliance.

"This underground river channel is formed by groundwater erosion, the reason why the river channel is wide and narrow, and the solubility of the geological erosion is related to the solubility of the geological flow erosion, the easy to dissolve the section is naturally widened under the erosion of the river water for a long time, and the narrow place is naturally the lot that is not easy to dissolve......

"Think too much, this stalactite is the limestone infiltrated into the water containing carbon dioxide, dissolved the calcium carbonate in it, you don't understand, in short, the limestone seepage water dissolves a certain substance in it, when the water drips, the dissolved thing solidifies again, bit by bit after tens of millions of years of accumulation into this. If you don't believe me, you can take a closer look and see if there is any dripping water at the tip of the bamboo shoot......"

Regarding Shang Shuqing's amazement at some of the underground landforms, Niu Youdao couldn't stand that such a smart woman could be so ignorant, and couldn't help but explain casually.

He walked in front and pointed at him, casually explaining, but Shang Shuqing was quite moved, followed behind and looked at the back of his head, and said with a complicated expression: "Master Dao, you know so much, even the changes in the underground." If you have the opportunity, please don't think Qing'er is ignorant, and teach me more!"

The corners of Yuan Gang's mouth twitched, and he muttered in his heart, why don't you ask about the changes in the sky.

"Do you know more?" Niu Youdao laughed and shook his head, simple common sense is good, but there is no need to explain this more, the more you explain, the more doubts you will have, you shouldn't have opened this mouth just now.

I don't know how long I walked, Shang Shuqing walked slower and slower, tired enough.

The key is to walk quickly all the way to catch up with the speed of the three men, and the soles of the feet have been blistered, and the pain is hot.

"Pay attention to the ditch!" Niu Youdao reminded, and when he looked back, he found that Shang Shuqing's walking posture was a little wrong, and asked, "Did you twist your foot?"

Shang Shuqing didn't say that the soles of her feet were blistered, and said stubbornly: "No, it's just that I'm a little unaccustomed to walking this way." ”

So he continued to walk forward for a while, and finally found that the woman was panting and sweating, and she really couldn't walk, so she came to a suitable place, a point where a large number of torches were stored, and the cow had a voice to rest.

Niu Youdao and the three of them can still walk if they have more than enough physical strength, and walking this little road is nothing to the three of them.

In fact, Niu Youdao meant that he wanted to continue walking with Shang Shuqing on his back, but Shang Shuqing refused to live or die, and came up with the words that men and women could not kiss, Niu Youdao had no choice but to give up, anyway, he was not in a hurry, just go slowly.

As everyone knows, for Shang Shuqing, it is already too much to hug her, if Niu Youdao hadn't done that suddenly when she went down the well before, she would have let Niu Youdao pull her hand down the well at most, how could she let a man hug her casually. It is even more excessive to let people carry their backs, and they lie on other people's bodies with their legs crossed, and their chests are close to other people's bodies? I can't accept it even if I think about it, so I naturally refuse to agree to death.

Niu Youdao can also understand the concept of chastity of women in this era, but he still added in his heart, I am not interested in you at all!

It is estimated that it is the reason why I have never walked such a difficult road since I was a child, and this way of walking is not normal and smooth, up and down, bouncing and jumping, which really makes Shang Shuqing tired enough.

After sitting down in a clean place in the corner, Shang Shuqing quickly fell asleep with his head tilted.

It was cold underground, Niu Youdao took a piece of clothing out of the package, and when he covered Shang Shuqing's body, Shang Shuqing didn't notice it at all, and slept very deeply.

And looking at Shang Shuqing's tired and miserable appearance, it is estimated that he will not wake up for a while and a half, and he may have to sleep for a long time. Although there is nothing unsafe along the way through the underpass, it is still necessary to maintain some minimum vigilance.

Niu Youdao is a class, and Yuanfang and Yuan Gang are in a class.

Trust is trust, and when Yuanfang is not yet able to let go completely, letting Yuan Gang accompany him is also to prevent accidents, don't be confused and be cleaned up by Yuanfang.

Yuan Gang watched first, and Niu Youdao sat there cross-legged and closed his eyes to breathe.

I don't know how long it took, Niu Youdao suddenly felt a chill in Qingming, a very abnormal chill, the normal chill is the whole attack, but this is a trace of drifting by, it is the kind of chill that can penetrate into the pores to inhibit vitality. This kind of chill can only be felt when you encounter something unclean in the ancient tomb, and Niu Youdao suddenly opened his eyes.

It happened that Yuanfang also came over, and when Yuanfang saw his sudden opening of his eyes, he knew that he had also noticed it, and whispered in his ear: "Master Dao, there seems to be a ghost here, just now I saw something flashing in the corner, sneaky, not necessarily with good intentions." ”

Niu Youdao recalled the feeling just now, the feeling was stronger than what he had felt in the Yin Land, obviously it had become the climate, not an ordinary ghost, in layman's terms, it had become a ghost!

"Check it out!" Niu Youdao gave a sigh, Yuan Fang nodded, turned around and lit a few torches, threw them in all directions, including the other side of the river, and then took another torch and floated around to look around.

Niu Youdao looked around, in this dark place, the first thing that came to mind was the problem of lighting, although the visual distance of the magic eye was beyond ordinary people, but it was also in the case of a light source, and it was useless to be completely dark.

He turned his head towards the place where the torches were stored, Yuan Gang immediately took a piece of clothing out of the package, walked to the place where the torches were stored, and broke several pieces with brute force in a row, and put a bunch of broken torch heads into the clothes, which were too long to wrap, and made a package and carried it on his body.

Niu Youdao got up with his sword and walked to Shang Shuqing's side, only to find that this woman didn't know what nightmare she was doing, but she was in tears in her dream, and her ugly face was full of tears, with an extremely desolate and nowhere to rely on. Being tired like this and still crying in a dream shows what sad things should be hidden in your heart.

"County Lord, County Lord......" Niu Youdao called twice, but couldn't wake up, so he reached out and slapped her face twice.

Shang Shuqing sat up straight in fright, looked at Niu Youdao in front of him in a daze, and then seemed to realize that he was crying, and raised his sleeves to wipe away his tears with some embarrassment.

When I got up, I found that I was covered with a piece of clothing, and I recognized that it was Niu Youdao's clothes, and my heart was warm, and I was a little shy, "Master Dao, did I oversleep." ”

Niu Youdao noticed that after she stood up, her feet stepped on the ground a little unnaturally, and said, "You can't go anymore, I'll carry you." ”

Shang Shuqing couldn't accept such a close behavior, and hurriedly shook his head and said, "My feet are fine, I can walk." ”

Niu Youdao: "You think too much, we are being targeted, and if you walk slowly, it will affect everyone." As he spoke, he looked around.

"......" Shang Shuqing was stunned, only to find that Yuanfang was gone, and there were torches thrown out in the distance.

Soon, she saw Yuanfang floating from the other end, and said to Niu Youdao: "Master Dao, I don't know where to hide." ”

"It's not a matter of spending here, let's go!" Niu Youdao tilted his head and handed the sword in his hand to Shang Shuqing.

Shang Shuqing was stunned for a moment, and when she received the sword in her hand, she was dragged over by Niu Youdao.

Niu Youdao didn't care how cowardly she was, after the person pulled her over, he reflexively scooped her two thighs with both hands, and directly carried the person behind him. He promised Shang Chaozong that as long as he was still there, he would protect Shang Shuqing's safety, and he was the strongest in the strength of the few people here.

This posture was too embarrassing, Shang Shuqing's pink ears instantly turned red, and his upper body didn't dare to stick to his back, holding his sword against his shoulder, supporting his upper body not close. Who would have thought that Yuan Gang handed her a lit torch again, and she couldn't answer it.

Several people left quickly, except for Shang Shuqing on Niu Youdao's body, several people maintained their original formation, still in front of Yuanfang.

Yuan Fang and Yuan Gang in front and behind each held two lit torches in their hands.

Without the burden of Shang Shuqing, the three of them marched a little faster several times, and the torches were whirring in the wind.

The melted fire oil dripped, afraid of falling on Niu Youdao's body, after a burst of ups and downs, Shang Shuqing had to lie on Niu Youdao's shoulder, and the two balls on her chest rubbed on Niu Youdao's back with the run, making her ashamed, lying next to Niu Youdao's cheek and exhaling like an orchid.

For her, it was not only that she was walking faster, but that it was certainly more comfortable to walk than she was to walk.

After quickly arriving at the next torch storage point, it was empty.

Yuan Gang walked into the hole in the wall, reached out and touched the oil stain on the wall, sniffed it before putting his nose, and turned around and said, "Yes." ”

Shang Shuqing, who was lying on Niu Youdao's shoulder, said: "It is impossible not to have it, this is a reserve land, and it is generally not used without permission, even if someone has used it, it will be reported, unless it is taken away by outsiders." ”

"Keep walking!" Niu Youdao tilted his head and signaled, and the three of them continued to move forward quickly.

Two more torch storage points were connected, and they found that they were still empty, and the torches in their hands were almost burning.

Niu Youdao looked around and suddenly said, "Old bear, pay attention to the river." ”

Round Square immediately dodged and floated out, treading the waves on the surface of the river, and as Niu Youdao expected, Round Square soon spotted the torches floating upstream.

The reason is very simple, according to what Shang Shuqing said, if there must be torches arranged at the storage points along the way, according to the previous stacking level, at least thousands, even if someone takes them, it is inconvenient to take them all together. According to the anomaly found before, if someone is only doing the ghost now, the most convenient way to deal with it is to throw it directly into the river.

Yuanfang fished out two torches and floated back, and overheated them with the lit torches, which were already soaked in water and difficult to ignite.

"Someone wants to hack us, don't fall into the hands of poor monks......" Yuanfang, who threw away the wet torch, looked around, cursing and scolding in his mouth, and anger appeared on his face.

Anyone could see that someone was trying to disrupt them, otherwise there would be no need to destroy the torch pit for them, and it would be clear that they would do so if they were going to deal with them.
