In order to save battery during rest, the flashlight is turned off. Lan Drunk reopened it to shine a light on the past, and the platform was covered with a layer of black mud similar to moss because of the perennial moisture. Lan Zui cleaned it with his sleeve, and the full shape of the pit was revealed.

Rong 13 also leaned his head over, only to see that the pit was no more than the size of a little finger, one end was quite deep into the stone, and a tail was pulled out in the deepest part, scraped out obliquely upward, getting shallower and shallower, and finally disappeared.

Rong 13 poked his finger into the deepest position, stroked it, and then shone it carefully with a flashlight, and said, "It seems to be a halberd." ”

"It's a halberd." Lan Zui affirmed, "The edge of the blade is three concave and two convex, which is the blood guide groove on the tip of the halberd. ”

Rong Shisan stood up and gestured empty-handed in the direction where the tail marks of the small pit disappeared, took another step, squatted down and continued to search, this time there was no trace on the ground, but after taking two more steps, it appeared again, and there was more than one place, the distance between the small pits was about the same, and the depth was almost the same as the direction of the tail marks.

"It seems that this person is holding a lot of weapons, and he will only knock on the ground if he can't hold it." Rong 13 concluded.

"Well, in this way, the Beiyan people are not as arrogant and reckless as the rumors, at least the two sets of tricks of closing the door and catching thieves and waiting for work are well played!" Lan Zui couldn't help but pat Bai Suhe on the shoulder, "Sister Bai, it's amazing!" ”

Lan Zui's fingers just touched the ground, and this pat made Bai Suhe's shoulders covered with mud. Bai Suhe's brows were just furrowed and she wanted to shoot, but Meng Zheng had already stood on tiptoe and reached out to brush it.

"I'll do it myself." Meng Zheng is short, and he looks very reluctant to tiptoe the soil. Bai Suhe was just about to do it herself, but Meng Zheng grabbed her wrist, and continued to play with her other hand.

Bai Suhe was stunned, and Meng Zheng didn't say a word until it was completely clean, and then sat back on the ground to rest.

Bai Suhe was still standing in place, stunned, Meng Zheng's changes were obvious, but she didn't know how to deal with it. Restoring Xia Ruoqing's memories of Meng Zheng pretending to be coquettish, she didn't fail to see it, and that kind of Meng Zheng always reminded her intentionally or unintentionally of Xia Ruoqing's various deceptions in the past with her delicate and lovely, and the more she pretended to be Meng Zheng, the more disgusted she became. Today's Meng Zheng is still intimate, but Huo Ran has torn through that layer of disguise, and the stubbornness reveals a strong force that cannot be refused, which is far different from the past, and it makes Bai Suhe feel a kind of anger that seems to be nothing.

What the hell is she trying to do?!

It was difficult for the Qing official to interrupt the family affairs, and the three people next to him wisely stayed away from the two who were obviously flashing lightning bolts. Jun Yihuang was drunk and continued to look for traces. She rarely touches these tricks, but she is smart, and she understands the current situation as soon as she is drunk. Based on what we have seen so far, the quicksand traps on the ground are huge in scale, and it is obvious that they are set up to defend against the enemy, plus the many ropes on the platform and the traces of the blades on the ground, we can already imagine the general process of the defense of this ancient city of Beiyan.

The location of this ancient city was already easy to defend and difficult to attack, and the city walls were built on the ridge of the city. Depending on the strength of the attacking enemy, it is decided whether or not to resist forcefully. The weak enemy will naturally be destroyed under the city, and the strong enemy will pretend to lose the city, lure the enemy into the city, and the soldiers in the city will take refuge in the stone houses of each room, shoot the quicksand mechanism, and let the incoming enemies fall to the ground. Jun Yihuang guessed that there must be more than just water and sand underground, and there were other deadly things. After the soldiers in the city waited for the enemy to die in the pit, they climbed down the rope through the various holes to collect the enemy's weapons for their own use. Jun Yihuang was born in Qi County, and Qi County relied on the rich iron veins in the country and outstanding smelting and casting skills to establish the country, and the weapons and iron weapons in the war era were the most scarce. Soldiers, treacherous ways, the practice of the city of Beiyan can be said to obtain the maximum benefit at the minimum cost, which can be called a must.

The platform was dark, and the floor was covered with black mud, so no one had paid attention to the tiny marks on the ground before. Only then did I find that there were many such pits on the ground, and they were the most dense around the caves. The shape of the pit can tell the direction in which the weapon-wielding men are walking. Naturally, it is necessary to use and distribute the weapons back, and at worst you can follow them to a hoarding point, which is better than going around in circles in the dark.

It's a good thing to have a road, and a few people didn't rest anymore, so they hurriedly kicked up the four of Reyimu who were sleeping in the dark, and walked all the way forward in the direction of the pit.

The more you walked, the more dense the pits became, and finally they gathered in front of a stone cave. Lan Zui jumped down to take a look only to find that the surface of this stone cave is the same as other stone caves, but the internal structure is completely different, the whole cave expands in all directions in the shape of an inverted trumpet, and the higher and higher it goes, the wider and wider, and finally it becomes a large stone cave that is both high and wide enough for a bus to pass, spiraling and winding downward.

The walls of the stone cave are rough, the main body is naturally formed, and the edges can be seen to be artificially leveled.

Lan drunk wiped the fine beads of sweat on his forehead, and his steps began to hesitate. They had been walking down for at least ten minutes, and according to the altitude, they were already far below the desert level, and they were getting farther and farther away from the ground, but they had not yet seen the meaning of the bottom. Where does this cave lead?

Recalling Reim's statement that Karubasazi is the abode of the devil, is this cave really leading to hell?

Everyone was worried in their hearts, and although they didn't say anything, they all had cowardice in their actions. Kanji was so young that he couldn't help but choke and cry after being in the dark for so long. Reyim and Sabir were hindered by their oaths, so they could only coax and deceive, and in the midst of this noise, the cave turned for the last time, and the flashlight light suddenly shot out, and there was no wall to stop it.

Everyone stood in front of the sudden opening of the cave, and they were stunned, even the cries of Kanji were paused.

Beyond the entrance is a flat area at least a few miles in radius. The reason why it can be judged so accurately is that about two or three hundred meters away from the entrance of the cave, there are pillars rising from the ground. It is not known what the material of the pillar is, but the carved patterns on the pillar are complicated, and what is even more bizarre is that those carved patterns actually emit a light blue light in the dark, just like the moonlight and stars, which can clearly reflect the scenery within a radius of one meter next to the pillar.

The positions of the pillars were staggered, apparently carefully calculated, echoing each other's rays, strung together and extending into the distance, and the number was innumerable. Farther away, there seemed to be a mist curling beside a row of pillars, obscuring the light of the pillars more and more dimly.

There was no sound in the entire area except for the faint sound of water coming from nowhere. Holy, eerie, feminine, eerie, no one could have imagined that these words could be used to describe the same landscape.

"I ...... I am...... Did you get to the city of hell? Reyim fell to his knees and fell to the ground, his hands on the ground, and muttered in Mok, his voice trembling as if praying. Sabir looked frightened and knelt down with Kanji. Although Xiri Ahong didn't know why, when he saw that his eldest brother was kneeling, he also 'banged' on the ground, and the ground trembled.

The group of Lan Zui next to them were very speechless to these four people, and let them go, leaving Bai Suhe and Meng Zheng to watch them, Lan Zui, Jun Yihuang and Rong Shisan cautiously walked to the nearest pillar, ready to find out.

When I got out of the cave, I found that the ground in this area was paved with a mixture of gravel and yellow sand, and although the foothold was uneven, it was very solid. In the section of the road before reaching the pillar, they shine around with flashlights, and the ground is not empty, and the closer you get to the pillar, the more debris is scattered. Lan Zui picked up a few pieces and looked at them carefully, most of them were fragments of armor, broken spears and swords, etc., I don't know how many years they have been shelved here, and they are rusty.

Further into the column lighting range, not only fragments of broken guns, but also relatively complete ancient combat artifacts such as half-body shields appeared.

Except that there is not a single corpse along the road, this place is like an ancient battlefield thousands of years ago.

"These things belong to Beidi." There was another shield on the ground ahead. This shield was much more complete than the previous one, Jun Yihuang bent down to brush away the sand and debris on the shield surface, and pointed to a totem that looked like a dragon and a snake around the edge of the shield, "This is the snake dragon, the holy beast of Beidi." When I was in Nantang, I once met the envoys of Beidi with Emperor Nanzhao, and their elite soldiers carried weapons with snake dragon totems. ”

Jun Yihuang circled around the place and whispered: "The ancient chronicle that Rong Jiu saw is not nonsense, the opponent of the last battle of this ancient city is indeed Beidi. Unexpectedly, Beidi actually broke the quicksand mechanism in the city and chased here. ”

Lan Zui and Rong Thirteen were also silent, and they didn't expect that the end of this cave was actually an ancient battlefield. It's just that there must be dead and wounded on both sides on the battlefield, why haven't a single corpse been seen so far? ”

This mystery was unsolved for the time being, and the three of them couldn't figure it out for a while and didn't think about it, so they walked to a stone pillar next to them to study. I didn't feel it far away just now, but now that I got closer, I found that these stone pillars were imposing. The height is more than 15 meters, and you can't see the top when you look up, and you almost feel like you are standing in the dark. The pattern on the column is engraved in shade, and the whole column is densely carved from the foot to the top. The gaps in the shadows were filled with a pale blue translucent material, and the misty glow was emitted from this material. Lan drunk stroked it through his clothes, the touch was soft and soft, and the stuff filled in was like a kind of gelatin, and when he got close, he could smell a fragrance that seemed to be absent.

"What is this?" The blue drunk circled around the pillar, this pale blue light was soft from a distance, but it was a little dazzling up close, but it made people unable to see clearly. Lan Zui took two steps back, squinted his eyes and looked up again, the more he looked, the more frightened he became, and hurriedly pulled Rong Thirteen together, pointed to the pillar and said, "Brother Thirteen, look at it, the one on this pillar is a hundred insect diagrams, right?" ”

The pillar carving was crowded, Rong Shisanyuan didn't see the reason, was Lan drunk and looked at it, and gradually separated the pattern, sure enough, the pattern carved on the pillar was full of scorpions, snakes, bees, snakes, centipedes and other poisonous insects, or twisted and cocked, or spread their wings to fly, or hovering and sticking out their tongues, or meandering and crawling, especially after the layer of light blue materials, the poisonous insects engraved on the pillar are even more lifelike, as if they will pounce out of the column in the next moment.
