Ye Da carefully wiped the gold coin with his cuffs, and at the same time explained: "Most of the coins in circulation in the Bohai Kingdom are copper coins, with the four characters Kaitai ingots on them, and the ones with Longji Tongbao are generally gold coins, and the gold coins are written with Longji ingots, just like the one I picked up just now." ”

After Ye Da wiped the gold coins, he carefully put them in his pocket, patted them with his hands, and looked at everyone again: "In addition, there are conforming to Tongbao and conforming ingots, but these two seem to have gold and silver coins, and I don't know very well, after all, after the Bohai Kingdom was annexed by the Khitan Annihilation State, many records disappeared in the long river of time." ”

Everyone nodded.

Ye Da saw that everyone was still looking at him, and hurriedly said, "Why are you stunned?" Let's go, this means that the treasure is beckoning to us in front of us, don't you want to get rich? ”

Tang Qianlin saw Ye Dana's appearance, there was no difference between him and Yi Mochen, he just smiled and continued to walk forward, without taking two steps, and stepped on a hard thing under his feet.

Tang Qianlin removed his feet and squatted down to look carefully.

Seeing this, Ye Da stepped forward and began to reach out and grab it in the mud, thinking that there was another gold coin, who knew that he would directly grab a bone from the mud.

"What is this?" Ye Da raised it and looked at it carefully.

Tang Qianlin glanced at it and said, "Human leg bones." ”

Ye Da hurriedly threw the bone directly to the side, while Tang Qianlin used the Xia Feng Gun to explore in the mud, and then picked up a lot of human bones with the head of the gun.

Li Yunfan also used the knife in his hand to find the white bones in the mud in front of him, and turned his head to look at Tang Qianlin.

An Ran looked at the white bones that had been picked out everywhere, and suddenly felt that this place suddenly became eerie and terrifying.

Could it be that the muddy road in front of you is full of white bones?

"Don't rush forward, look carefully in the mud around you to see if there are any weapons and armor or anything like that." Tang Qianlin instructed everyone to start rummaging.

Everyone looked around according to what Tang Qianlin said, and after looking for a long time, Fadeev picked up an iron chain from the mud with a knife: "There is an iron chain. ”

Immediately afterwards, Ni Xiaowan also picked up an iron chain: "I also found an iron chain." ”

Tang Qianlin walked up to the two of them, looked at the iron chain, and then looked in the direction from before: "Everyone, I have a bad premonition. ”

Li Yunfan asked, "What's wrong?" ”

Tang Qianlin said: "I feel that there is something in front of me. ”

Qian Sinian asked, "Why do you say that?" ”

Tang Qianlin said: "Iron chains, white bones, no armor, no weapons, this shows that the people who died here are not the warriors of the Bohai Kingdom, but those slaves or people who were captured here for experiments, I have seen a lot of this form before." ”

Qian Sinian wondered, "What do you want to say?" ”

Ye Feng said from behind, "He suspects that this is a place of sacrifice. ”

"Sacrifice?" Li Yunfan looked at Yefeng, "Mom, what do you mean?" ”

Ye Feng stepped forward and looked into the depths of the canyon: "In some religions or ethnic groups deep in the mountains, there is its own holy place or the road to heaven that is defined as the way to heaven, and in this kind of place, it is common to use sacrifices to open the way, usually slaughtering sheep and cattle, and in some places it is murder and sacrifice. ”

Tang Qianlin continued: "In some places, it's because there are some kind of ferocious animals hidden on the road, sheep, cows or people, all for these animals to eat. ”

When everyone heard this, they couldn't help but look around, for fear that some fierce beast would suddenly come out of the surroundings.

Ye Da asked: "What did An Guotao say?" ”

An Ran said: "My father said that he brought someone to investigate, and it is indeed possible to go outside, and he will not lie." ”

Tang Qianlin said: "Maybe when President An came last time, he was lucky and didn't encounter anything, but he said something very strange. ”

Yefeng asked, "What's the matter?" ”

Tang Qianlin said: "Originally, the three subordinates he lost were all on the road just now, accidentally triggered the mechanism and died, and when they came back to clean up the corpse, they found that the corpse was gone. ”

Hearing this, everyone became even more nervous, obviously because there were creatures around, and they were bloodthirsty and cannibalistic.

Fadeev asked tentatively: "Maybe there are also that kind of spiders here?" ”

Tang Qianlin said: "Maybe, I just want to remind you, in short, there is still a long way to go, you must cheer up." ”

After Tang Qianlin finished speaking, he looked into the distance and took a deep breath, and slowly walked towards the front with the lower phoenix spear.

While moving forward on the muddy road of the canyon, everyone realized according to what they were stepping on under their feet that the road was paved with white bones, and they did not know how many people had died here back then.

Just when Tang Qianlin and the others went deep into the canyon, the eight-eyed puppet spiders that tracked down slowly walked towards the mouth of the canyon, but stopped at the mouth of the canyon, as if they were afraid of something, and then slowly retreated and disappeared into the darkness.

After about 100 meters in the canyon, the road was blocked, and there was a stone wall in front of them.

Qian Sinian stepped forward and looked at the stone wall and said, "Is there a dead end?" ”

Tang Qianlin shone a flashlight on the top of the stone wall: "You have to climb up." ”

Qian Sinian turned his head to look at him: "And then?" ”

Tang Qianlin said: "After climbing this stone wall, there is a cave on it, and there is a stone wall, and you have to climb up, and then you will reach the exit." ”

Ye Feng thought for a while and said, "It looks like a staircase-shaped cave, this kind of cave can't be naturally formed, it should be excavated artificially." ”

"Where's the jelly beans?" Ni Xiaowan found that the jelly beans were missing, and looked around, only to find that the jelly beans were pooping against the bottom of the stone wall.

Jelly Bean pouted his buttocks, and at the same time looked up at Ni Xiaowan with helpless eyes, as if to say: I've been holding back for a long time.

When the jelly beans were finished, and before she waved her paws to dig the soil to bury them, Ni Xiaowan picked up the jelly beans.

Ye Da subconsciously used a flashlight to shine on Jelly Bean's, and when the flashlight was illuminated, he found that there seemed to be some pattern under the cave wall.

Ye Da squatted down and looked carefully, Ni Xiaowan didn't know the situation, frowned and said, "Are you sick, and you still go to study cat?" ”

"Old Tang, come on, there are not only pictures on this, but also words." Ye Da shined a flashlight on the stone wall, "You have to get closer to see it clearly, it seems to be written in cinnabar." ”

Tang Qianlin immediately squatted to Ye Da's position, and sure enough, he found that there were words, as well as simple patterns, he held a flashlight and carefully followed the beginning of the text on it, and finally found it in the upper right.

Tang Qianlin leaned in and looked at it carefully: "It's regular script, it's neatly written." ”

Li Yunfan also stepped forward to look: "It seems that it is not from the Bohai Kingdom that stayed, it should be from the Tang Dynasty." ”

Tang Qianlin didn't speak anymore, just looked carefully, slowly moved his body, and carefully read the words that were not clear on it.

After a long time, An Ran finally asked, "Qianlin, what is written on it?" ”

Tang Qianlin sighed and said: "The person who left this text is a guilty craftsman in the Tang Dynasty, he didn't leave his name, he just said that he came here to help the Bohai Kingdom build a tribute city, also called Bao'en City." ”

Fadeev was puzzled: "Tribute City? Repay the city? What do you mean? ”

Tang Qianlin explained: "The Bohai State was a vassal state of the Tang Dynasty at that time, and they built this city to show their loyalty to the Tang Dynasty. ”

The craftsman who left these records did not leave his specific name, but only said that he had offended the wrath of heaven, presumably offended the emperor at the time, so he was sent to the Bohai Kingdom.

The city is divided into three areas: the inner city, the new city and the outer city, and the underground passages are connected under the three areas, according to the craftsmen, when they excavated the underground passages, they originally wanted to design them as multi-layer secret passages to confuse others, but who knew that in the process of excavation, they found that there was a huge strange cave hidden underground.

Not long after the cave was dug up, many people in Gongcheng became crazy, seemed to be possessed by demons, and began to kill and eat people, Bohai sent troops to arrest and suppress such people, and began to search around, bringing some people suspected of being possessed by demons to the underground cave, trying to find out what happened to these people.

The most bizarre thing is that a large number of tributes that were originally prepared for the Tang Dynasty suddenly disappeared.

Tang Qianlin looked at the text on it and said, "It seems that during the Bohai Kingdom period, there were also people parasitized by female spiders here. ”

The Bohai Kingdom dispatched their so-called national teachers, as well as some so-called masters of demon slaying and demon slaying to find out all this, but it backfired, and many people died in this cave as a result. Later, a shaman appeared and told them that they had caused this evil because they had disturbed the gods in the cave, but that the cave had been dug and that the only way to appease the wrath of the gods was to use sacrifices, and that living people had to be used.

Because of the attack, and the complaints of the people, in order to quell all this, the Bohai Kingdom decided to try according to the shaman's words, so the group of people possessed by demons and some of the condemned prisoners were brought here to be sacrificed.

After reading it, Tang Qianlin said: "This craftsman is also a death row prisoner, so he was brought here, and then discovered the secret of the shaman and the official in charge of the construction of the tribute city, and the two joined forces to attack the tribute, so they designed all this, and the missing tribute was quietly transferred here by the officials from the ground, and it seemed that it was the treasure that President An said, but the craftsman said that the shaman seemed to be able to manipulate the demon." ”

Everyone was shocked when they heard this, glanced at each other, and then looked at Tang Qianlin.

Fadeev said: "Manipulating the demons!? ”

Ye Feng said: "Does the craftsman mean that that shaman can control the eight-eyed puppet spider?" ”

Li Yunfan shook his head puzzled, Qian Sinian also looked puzzled, and An Ran leaned close to Tang Qianlin, looking very scared.

Ni Xiaowan hugged Jelly Bean, and Jelly Bean also looked very uneasy, burying her head in Ni Xiaowan's arm.

Qian Sinian said: "It's unlikely, right? ”

Tang Qianlin said: "The above text record has not been written, there is a stone wall on it, let's climb up and take a look, maybe we can find something." ”
