Po Xi and the others were on the way to join the Qin army, and Ying Zheng had already known the news that Po Xi had left Shu to join him earlier. He was very satisfied with her decision.

After the two met, because they were marching and fighting, they didn't have time to spend the previous month and the next month, so they could only devote their minds to the war.

Ying Zheng had already learned that the number of the Shu King's army was far more than he knew, and in terms of numbers, the Qin army was definitely in a weak position. Even if he sent more soldiers and horses to support one after another, just in case. But far water can't quench their thirst, and if they fail in the first place, the consequences are unimaginable.

Ying Zheng faintly felt that maybe he was conceited this time, thinking that he couldn't turn the sky over in just one place, so he only docked 150,000 soldiers and horses before and after. The topography of Bashu is undoubtedly a challenge for the Qin army. However, fortunately, the soldiers and horses of the King of Shu may not be familiar with the terrain here like them, that is to say, the two armies are opposite, not only in terms of numbers, but also in occupying favorable terrain is also a very important condition for victory.

But with Wang Qian's leadership, if there is no problem, Ying Zheng believes that the probability of 150,000 soldiers and horses winning more with less is still very high.

Wang Jian led the army not to go directly to Fenghuang Town, but stopped and set up camp in a place with low surrounding mountains fifty miles away from Fenghuang Town.

Because it is a stone mountain, there are no dense trees to block it, so you can see the surrounding area at a glance. This is the most favorable terrain for the exchange between Bashu and Shu, and Wang Jian chose this place as the base camp of the Qin army from the beginning.

After the army stopped, Wang Jian immediately sent people to climb to the top of the mountain in front and back to closely observe the movement. Because the army of the King of Shu had already occupied Phoenix Town two days ago, they could attack at any time.

Ying Zheng and Wang Qian, Meng Tian and others were discussing how to send troops and horses to attack and block, and someone outside reported that the secret guard was asking to see him.

Ying Zheng let the dark guard come in, and as soon as the dark guard came in to see the salute, he reported: "King, the leader of our dark guard, Miss Dugu and General Liu and others have been missing for a day and a night, and the original leader ordered us to wait for his instructions, because the king of Shu has already garrisoned Phoenix Town with a large army, and our actions cannot be careless." However, no matter who our secret guard is, if we have not contacted each other for more than a day and a night, it means that something has happened, and we dare not take the initiative to make the next move, so we came to listen to the king's order. ”

Po Xi listened beside him, guessing that Liu Chang and the others had an armory left to deal with, and if something really went wrong, something must have happened there.

"Can your chief tell you where they have gone?"

Perxi doesn't know how the Dark Guards are in contact, their appearance is always covered with their faces, and only they know how to distinguish each other from each other. Therefore, if their leader personally goes out on a mission, then he must have an account for his subordinates.

"Mrs. Hui, the leader said, we also know where. In fact, I didn't see the leader come back in the middle of the night last night, and our two brothers went to the end of the night where the King of Shu made weapons to investigate, and they didn't see a single person, but they found that there was a hare that seemed to have been poisoned and died at the scene, and this. The guard took out a green handkerchief embroidered with white lotus flowers.

When Poxi saw it, she recognized that it was Duguqing, she liked lotus, so she always liked to use lotus flowers for proofing. That proves that Uncle Qing and Sister Qing have been to the armory.

"This is Sister Qing's veil, which means that they did go there."

"Then how did they disappear?" The questions Meng Tian asked were all wanted by the people present, but I am afraid that no one knew the specific situation except for the disappeared people.

"We don't know the situation now, but the leader has never disappeared like this, so ......" The Dark Guard bowed his head with some guilt.

"I don't see people, but what about weapons, have you seen them?" Meng Tian suddenly remembered that he had heard Liu Chang say before that there should be a large number of weapons hidden there, and they would only leave them in order to destroy those weapons.

"There are still weapons, at least 10,000 or 20,000, so we are even more strange. The leaders seemed to have disappeared into thin air, without a trace. ”

"King, what should I do now, will it be the King of Shu who ...... them" Meng Tian was a little worried, he knew that he would not care about those weapons, and there would be no such thing if he returned to join the army together.

"Continue to investigate, all of your secret guards who stayed in Phoenix Town are divided into two teams, and one team continues to pay close attention to the situation of the Shu army. The other team went to find people, even if they dug three feet into the ground, to find their whereabouts, and the king believed that they were still alive, and as long as they were alive, there would be traces. ”

Ying Zheng gave an order to the dark guard, and the dark guard quickly left and returned to Phoenix Town to convey Ying Zheng's order.

Xuanyuan Daokang also began to worry and said: "If they are really captured by the King of Shu, I'm afraid it will be dangerous."

Mo Shangxuan is a despicable person who has no bottom line, and he keeps saying that he is sincere to his sister, but he doesn't even let go of his sister's use value, and wants to take it for himself. finally rescued his sister back, Duguqing, who he cared about, may have fallen into Mo Shangxuan's trap again, and recently because of these things, he has been at peace.

In order to stop Mo Shangxuan's conspiracy, although his own strength is limited, it is not as simple as imagined to see the situation. Therefore, he actually mobilized all his forces to prepare and join the Qin army against the rebellion in Shu at any time. It's just that when the time comes, it is really necessary to dispatch those tens of thousands of horses, and I don't know if King Qin will blame him for raising so many soldiers and horses privately. Although it was a last resort to stabilize the daily life of the border people, it still violated Qin law after all.

Regarding Duguqing's unexplained disappearance, Wang Jian had a different opinion, and said: "No, if they are really controlled by the King of Shu, they will not be in danger of their lives for the time being. And if there is something unusual in the Shu army, the dark guards will also notice it. So, they may be doing something else right now, but the good news can't be delivered. ”

Wang Jian had a clear mind, but he was a little worried about the rare thing in his heart, Duguqing's face suddenly appeared in his mind, he had never thought of her when he was concentrating on the war, but now he heard that she was missing again, and he was unconsciously worried about her.

Last time she was kidnapped, he secretly asked the leader of the secret guard to cooperate with Feng Daicheng to rescue her before he went to join the army, it was only a few days, how could she disappear again, although she was not the only one who disappeared this time, but because she was also among them, he was a little beyond his usual heart to face such a thing.

Po Xi agreed with what Wang Jian said, and also said: "General Wang is right, I also vaguely feel that it has nothing to do with the King of Shu, first of all, the King of Shu does not know that we already know the stronghold of the armory, so he naturally will not prepare in advance to besiege Sister Qing and Uncle Qing." So, there should be another reason for their disappearance. ”

But she can only think of this, and the rest can only wait. Deep worries are crawling all over Perxi's body and mind, when will they be able to live a good life?

Ying Zheng hugged her tightly and comforted her wordlessly, and Perxi obediently leaned into his arms, feeling the strength and support he gave. Everyone else who was interested in it retreated.

However, Poxi and Wang Jian were right, Liu Chang's disappearance really had nothing to do with Mo Shangxuan. It can be said that it is an oolong that makes people speechless and choked.

At first, everyone already knew that the weapons created by Mo Shangxuan were extremely inhumane poisonous weapons. Originally, everyone was going to start destroying those weapons, but who knows, Liu Changdong explored and touched around, and he opened a two-meter-wide stone door without knowing why, and there was an artificial secret passage inside, and he knew that there was a situation at a glance.

Everyone was curious, and they all followed in to find out, who knew that when Liu Chang hadn't opened his mouth to tell everyone not to mess with things, Duguqing stumbled forward and pushed forward, just pushing a round stone in front of her. As soon as the cobblestone turned, the stone door slammed and shut them all inside.

"Oops, it's over!" Liu Chang almost cried, this mechanism is dead, and he can barely get out from the inside when the door is closed, unless the stone door is split. But who has the ability to split such a heavy stone door.

"What, can't the door be opened again?" The leader of the dark guard patted the stone door, and it didn't loosen at all, just like it was originally a stone wall.

"Hey, Dugu, can you not make a mess, how can you ......." Liu Chang didn't know what to say, there was one of these kinds of organs, once the door was closed from the inside, the people inside wouldn't want to go out.

"What the hell, this ball can be closed when it rotates, and it can be opened if it turns again." As soon as Dugu Qing finished speaking, he turned the stone ball again with a creak, and there was another rumble at the gate, but instead of opening the door, another stone door fell from top to bottom with a clatter. The stone gate almost smashed the leader of the Dark Guard, but he reacted quickly enough to dodge.

"Hehe, Dugu, you have completely and successfully locked us inside." Liu Chang stared at Shimen in despair, wanting to cry without tears.

"What, the first time I didn't mean it, the second time you didn't say it, and it wasn't all my fault." Duguqing seemed to know what he had done, but he was reluctant to admit that he was stupid.

"Ancestor, have you given me a chance to speak?"

"Then if you don't mess with this thing in the first place, we won't come in, and if we don't come in, I won't touch something that shouldn't be touched by the way."

"You ......"

"Well, now is not the time to argue about who is right and who is wrong." The leader of the secret guard interrupted the two of them, who didn't know whether they were alive or dead, and saw that they had stopped arguing, before he asked again: "General Liu, what kind of mechanism is this, since you are familiar with it, there should be a way to open it, right?" ”

"I don't have the ability, and when the old man of the public loss class designed this mechanism, it would be difficult to open it as long as he closed a door from the inside, but there was still a chance. But unfortunately, our Dugu ancestor also used the second door, not to mention me, even if my master is here, he has no ability to open it. ”

"Lost class? Could it be the legendary inventor of the Spring and Autumn Period and the Warring States Period ~ Lu Ban? ”

"That's right, it's Luban you said, you touched one of his most powerful organs, I thought that only my old man still knew this kind of mechanism, but I didn't expect that there were people in Shudi who understood it, and designed such a mechanism that was about to disappear, and now it is impossible to return."

"Wow, that's amazing, now I really believe that Lu Ban is a great scientist." Dugu Qing was greatly surprised, he didn't expect Lu Ban's organs to be so sophisticated, and they would not be worse than those high-end technologies in two thousand years, let alone now.

"You are still in the mood to sigh that he is an old man, don't you know that he is so powerful that we will all be trapped in this?" Liu Chang really wants to shoot Duguqing to death, when is it, she is still fine.

"So what should we do, we won't really die here, will we?" Only then did Dugu Qing know that the matter was very serious.

"There should be an exit here."

Feng Daicheng raised the torch and shone it on the front passage, and found that there was an oil lamp tray on the stone wall not far away. He walked over and lit the oil lamp, and the passage became brighter. Liu Chang looked at it and took the lead in walking forward, and everyone followed one after another.

"Feng Daicheng, you don't know the situation here at all? Anyway, you can be regarded as mixing up on Mo. Dugu Qing asked suspiciously behind Feng Daicheng, looking at his appearance, it seemed that he didn't even know where the armory was.

"Five years ago, the King of Shu and my father began to deliberately avoid me from carrying out some more secret plans, and I didn't bother to participate because of the resistance in my heart. Crafting weapons started about five years ago, but this place must have been built much earlier. ”

"Then you... This can be regarded as a complete break with the Feng family and your father, you have betrayed the Feng family's inheritance of loyalty to the Shu King family for generations, can you live in your heart? Seeing that everyone was in front, Duguqing and Feng Daicheng were a little behind, and Duguqing asked Feng Daicheng about this sensitive issue.

"When I didn't know so much, even if my father told me that our Feng family should fully support the plan of the King of Shu against Qin, although I was only a teenager at the time, I also knew that the Feng family was a generation of retainers of the Mo Shang family, and I had the responsibility to follow. So for a long time, I was really willing to listen to the arrangements of the King of Shu and my father, but later, ...... Feng Daicheng recalled that he learned how this so-called anti-Qin plan was formed step by step, and he couldn't say it anymore.

Dugu Qing listened to Feng Daicheng's explanation, and roughly understood his position. As the heir of the Feng family, he should have been loyal to his father. But because the direction of his heart was contrary to the king of Shu and his father, there was an estrangement. But he can't completely break away from the Feng family because of this, and the entanglement is afraid that only he understands.

Now, perhaps forced by the situation that he can't have both, he finally chose his conscience. In this regard, Dugu Qing completely let go of his prejudice and dissatisfaction with Feng Daicheng from his heart, and instead sympathized with his helplessness.

Since the back road has been blocked, everyone can only continue to move forward, going deeper and deeper, and the passage seems to have no end. Under the light of the torches, you can clearly see the deep traces of the wheels of the two carts, which are obviously left by the long-term moving back and forth.

Liu Chang, who was walking in front to lead the way, suddenly stopped, he motioned to everyone not to make a sound, he listened carefully, touched the stone wall again, and asked, "Do you hear the sound of water flowing?" ”

"That's right, there's the sound of running water." The leader of the secret guard is a talent personally selected by Wang Qian, and his martial arts are naturally not low. The ears of people who practice martial arts are always stronger than ordinary people.

"If there is a flow of water, it means that there is an outlet, haha, I said, how can my life be so worthless." Duguqing became excited, it seems that God doesn't plan to let her die.

"You're going to have to be scared, and you don't see who caused the trouble." Liu Chang couldn't stand her, a woman, she was still not afraid of death at this point.

"Cut, Miss Ben didn't mean to."

Liu Chang didn't bother with Duguqing anymore, but touched the stone wall and continued to walk forward. He found that the stone walls were getting wetter and wetter, and the air seemed to be getting colder, almost cold.

Finally, Liu Chang saw a big exit, and the sound of gurgling water became clearer in his ears, but he couldn't see where there was water. He watched carefully, making sure there would be no more mechanisms before slowly walking to the exit. However, they found that there were sloping steps outside the exit, and at the end of the steps was a river, which could continue on both sides. The key is that the top of the river has many strange shapes erected down, round and pointed stone pillars, and different colors and shining, under the light of the torch, it is even more dazzling, like hanging full of dazzling jewels to attract people's reverie.

"I've grown so big, it's the first time I've seen such a golden river in the mountain!!" Sun Mo was the first to sigh at this magic.

The others actually haven't seen it, they are all secretly surprised, Dugu Qing looked, not as fuss as they were, saw them with admiration, shook his head, and explained to them like a mentor: "This river is called the dark river, and those stone pillars that hang down like stones are called stalactites, or fluorite, which are generated by the geological action between hydrogen fluoride and calcium carbonate, and it seems that this is a typical karst cave landform." ”

“……”

“……”

“……”

“……”

"When I didn't say it, you can think whatever you want, but it's not dangerous, you can rest assured." Looking at the eyes of a pair of flying over, Duguqing found that there were some things that could not be explained, and the generation gap was too far away to communicate.

"There seems to be a raft over there, and we can take the raft to find the way."

Anyway, no one understands, and everyone doesn't care about what the "Book of Heaven" explained by Duguqing is for the time being. After the leader of the dark guard came back from the lead, he pointed to the right side of the river, and everyone looked over, and sure enough, there were several rafts docked on the right side of the dark river.

"But which way should we go?" Sun Mo looked left and right at the dark river, and he could walk on both sides, but he didn't know which side was the right way out.

"Of course, it goes downstream, and where the water goes, there is an outlet." This bit of common sense is not difficult for Liu Chang, after all, he grew up dealing with landscapes.

So they parted ways and paddled on two rafts and rowed along the calm river.

"It's strange how this water is as cold as winter water, it stands to reason that the water in the dark river should be very comfortable." Duguqing put his hand into the water and felt the abnormal water temperature, but he only knew a little bit about geography, and he didn't know why it was abnormal.

"What's so strange about this, after all, it's a dark river that doesn't see the light of day, isn't it normal to be cold?"

Liu Chang explained according to his own understanding, and Duguqing couldn't help but say: "What do you know, it's hard to have hot magma under this dark river, so even if the water of the dark river is not hot, it shouldn't be so cold." ”

"What the hell is magma?" Liu Chang asked as he swung the wooden paddle and paddled it.

When the magma is not "angry", it flows quietly in the center of the earth like a river, and if it is "angry", it will destroy the city by the dead, and it will have the ability to destroy the world at worst. ”

"I'm talking nonsense again, I really don't know what you grew up eating, and every day your mouth is jumping around with something that people can't understand."

"Hey, there is a generation gap of thousands of years, and it is a waste of saliva to talk too much." Duguqing sighed, no one in this world understands her, communicating about science, she is always very lonely, hey!!

Liu Chang thought about it, and suddenly remembered that the waterhole where he and Xuanyuan Wenmei fell that day was also very strange, it was also a waterhole, why it was hot on one side and cold water on the other, it really couldn't be explained.

"Dugu, have you ever seen water in the wild that can be hot without boiling?"

"Yes, that's what natural hot springs are."

"Have you ever seen the same lake, hot on one side and cold on the other?"

"I haven't seen it, but there are indeed cases of this, and there are still many things that cannot be explained by nature."

Liu Chang stopped suddenly, he tried the temperature of the water in the dark river, and the feeling of this temperature was exactly the same as when he swam to the cold side of the waterhole that day.

"Feng Daicheng, is the Shu Palace far away from this mountain?" Liu Chang asked Feng Daicheng, who was also on a raft.

"The mountain on the right side of the Shu Palace, separated by the golden silk nanmu forest, is the poison peak, and the mountain range on the side of the poison peak is where we are now. That is to say, the mountain range where we are located can be seen from the mountain behind the palace of the king of Shu. ”

Duguqing seems to have heard a little tired, as long as it is connected with the Shu Palace, everything seems to be falling out.

However, they have not yet reached the root of the truth, and if they want to be uprooted, they must continue to explore, but several of them are trapped in the underground river, and there may be a war going on above. Duguqing was worried that if they did not inform the Qin army in time of the poisonous information about the weapons used by the Shu king's army, it was likely to cause the Qin army to receive heavy losses, and Yingzheng and Poxi might also be in danger. In short, the situation is not good, and they have to leave here as soon as possible to help the Qin army.

But if you think about it, it's not necessarily a bad thing that they're trapped here, since it's so hidden and well-connected, maybe Mo Shangxuan has more secrets buried in this unknown underground mechanism. It just so happened that they could solve it together, and they would catch Mo Shangxuan off guard, and he would be angry if he didn't kill him.
