The ground war was in full swing, and the Qin army suffered serious setbacks, except for defense, it was already exhausted for the time being. And Liu Chang and others in the underground river have been trapped for a few days.

In fact, it was not that they did not find the exit, but when they reached the end of the river, there were two forks, one leading to the left, but the waterway was getting narrower and narrower. But the obvious water is flowing out. And Liu Chang had a hunch that the place where the water went out was likely to be the deep valley where he and Xuanyuan Wenmei jumped into. But at the end of the waterway, there is no exit, only a closed mountain.

The last passage is to keep going, the exit is found, and it is also a passage to go up and walk around. When they had walked a long way along the passage, they found that the passages in front of them had been hollowed out on both sides, turning them into storage rooms with a large number of weapons in them.

"I understand, this passage should lead to the Shu King's Palace, and these weapons are the inventory of the Shu King. In addition to personal use, there should be an intention to sell to others. Feng Daicheng speculated according to the geographical direction that the location of the Shu Palace would be further down here.

"Yes, that's right, I vaguely remember that I was led into the basement and fainted after falling into their mechanism, and it was this kind of place that they took me to in a daze."

Liu Chang also suddenly understood that some of these mountains are naturally formed, and some are artificially transformed. In the end, they were all used by the Mo Shang family to dock with the Shu Palace, and even if they didn't leave the Shu Palace, they could control the poison peak and the arsenal.

With such a dark natural barrier, you can completely avoid being snooped on in broad daylight, and you can do whatever you want. That's why he secretly did so many vicious things, and no one knew.

"In this way, is it possible that Poison Peak can also go straight to the Shu Palace? If so, is there a large amount of medicine stored in the passage like here, at least there are countless weapons stored here, and what is more convenient than placing it in the passage? ”

Dugu Qing turned her brain, she recalled that when she was swimming on the back of the Sky Beast, the geographical location around the Shu Palace was indeed unique. First of all, on the right side of the Shu Palace, opposite the Golden Silk Nanmu Forest is the poison peak, and on the side of the poison peak is the armory. The armory mountain is docked to the back mountain of the Shu Palace.

In this way, Duguqing formed a structural diagram in his mind, that is, the two mountains of Poison Peak and Armory Arsenal are docking at the same time to support the Shu Palace, forming an isosceles triangle, with the Shu Palace being the top, and the Poison Peak and the Armory being the pillars.

Thinking about it this way, it proves that the three places are definitely passable with each other, that is, the place where they are now may also be able to reach the mountain body of Poison Peak.

Thinking of this, Dugu Qing became excited, and immediately said to Liu Chang: "Liu Chang, you study it carefully, is there any other mechanism that can be opened here, I think this place may be able to lead to the poison peak." ”

"I've guessed too, I'm looking closely, but I can't see where there is a mechanism for the time being." Liu Chang looked around, but really didn't find anything special.

"If you extrapolate according to the geographical location, the passage should be the Shu Palace, and the mechanism of the Poison Peak Passage can only be on the right side of the passage, so let's look along the stone wall on the right and the weapon storage room on the right, if there is an organ, it must be set on the right."

Everyone felt that Duguqing's judgment was reasonable, and Liu Chang also listened to her opinion and only paid attention to the place on the right.

Feng Daicheng looked at Duguqing, he used to know that she was very smart, and many things were uneasy and common-sense cards, which was always unexpected. It's understandable that she doesn't follow the usual path, but lately I've discovered that almost no one knows what she knows. He began to doubt Duguqing's true face, maybe she was not the original Duguqing at all.

"Why do you always know something that others don't know, and say a lot of things that no one else has heard, who are you?"

Feng Daicheng asked in a low voice about his curiosity about her, when he inquired about her, he only heard that she was a young lady from a merchant family, with a gentle temperament and good manners. It's not what it looks like now, is it really the legend that she can't find death, and her temperament changes drastically after waking up?

"You don't understand who I said, anyway, I'm Duguqing now, as for what I know that you don't know, you just treat it as if God told me in a dream."

Regarding Feng Daicheng's curiosity, Duguqing didn't bother to explain too much, and he was afraid that he wouldn't even believe it if he talked too much.

"If you want me to say, Dugu may have taken the magic medicine of the gods, and his brain is open, and he can think of anything." Liu Chang interjected, then touched the stone wall in front of him that was polished a little different from other mountains, groping up and down.

"You're right, I've really eaten ...... for thousands of years"

"Found it." Liu Chang suddenly shouted and interrupted Duguqing's words, and everyone looked at Liu Chang with a smile and his face against the stone wall in front of him, lying there directly with his hands and feet, intoxicated by it.

"People who don't know still think you're holding a lover, this virtue." Duguqing walked over and kicked at the stone wall, his face full of contempt for Liu Chang's naivety.

"Ah~ Ancestor, stay away." Liu Chang shouted at Duguqing, cautiously looking at Duguqing's leg raised again, afraid that she would really kick the place where she shouldn't have kicked.

Not only Liu Chang, but the leader of the secret guard also pulled Dugu Qing away from the wall, and even Sun Mo said weakly: "Miss, you are the best at doing nothing now." ”

"Okay, I understand, I'll step back, I'm not close there, I'll stick to the wall on the left, don't go anywhere, you're busy, I won't bother, okay?" Duguqing touched her ears and slowly retreated, not daring to resist their distrust of her, who made her troublesome, had already closed a door, so that everyone still had palpitations.

"That's right, if you don't move, we're all safer." Liu Chang nodded, and after adding a knife to Duguqing, he carefully studied the door.

But Liu Chang was busy for a long time, but he couldn't find the mechanism to open the door. Duguqing was so bored that he leaned against the wall and sat down directly.

It was estimated that when it was time to eat, she felt hungry and said to Sun Mo: "Sun Mo, you go and get a few fish, I'm hungry." ”

Sun Mo answered yes and picked up the long sword and went back to catch fish in the dark river, if there were no fish and water in the past few days, they would probably starve to death here.

Soon, Sun Mo came back, spread out the cloth bag in his hand in front of Dugu Qing, and four or five fat and big baby fish appeared, still jumping violently.

"Miss, do you want to keep one for that sashimi, or will I cook it together and you will eat it?"

Looking at the Chinese giant salamander in front of him, Duguqing was very reluctant, and sighed: "Hey, what a sin, if this was in that era, these baby fish were first-class protected animals, according to the amount we ate in the past few days, it is estimated that we can sit through the prison." ”

Sun Mo shook his head, his young lady's thinking was gone astray again. I didn't ask her at all, I used a short sword to deal with the baby fish, and then inserted it into the short sword and put it on the torch to roast.

The others couldn't find the mechanism for a while, and they planned to feed their internal organs first. After everyone had eaten, Duguqing was still sitting against the stone wall, looking at Liu Chang from the bottom up and asking, "Liu Chang, are you sure that is really a movable door?" ”

"Sure, but this door is different from the one over there in the armory, usually this kind of mechanism is either above or below the door, but there is no up or down here, it's very strange."

"So if we can't find the mechanism, we'll either die here, or we'll have a chance to go out when Mo Shangxuan's people come to move things?"

"If that's the case, then there's no choice but to wait for someone to open the mechanism."

When Dugu Qing heard this, he was a little desperate and knocked on the stone wall behind him with the back of his head, and said: "In this case, it's hard to make sure that the Qin army has been defeated, even if we are not in a hurry to go out, what can we do about the safety of Poxi and the King of Qin, the weapons used by Mo Shangxuan will really make the Qin army suffer a big loss." ”

As she spoke, she knocked the back of her head twice in a row, but before she could knock it a fourth time, a stone suddenly rose on the floor of the passage, and the door on the opposite side clicked, and a stone protruded from each end of the middle of the door. Then they saw the door open.

Dugu Qinglu jumped up, opened his mouth unbelievably wide, his eyes widened, and he said weakly: "This... I didn't do anything, I couldn't have opened it, did I? ”

Liu Chang pulled her away, looked at the wall behind her, and finally understood that the place where the mechanism he had been unable to find was originally blocked by Dugu Qing. First, he only believed that the starting place must be on the other side of the door, and secondly, Dugu Qing was blocking it, and he didn't notice that the mechanism was on the opposite side of the door.

Coincidentally this time, the organ was still touched by Duguqing's crooked beating, but fortunately, this time it was a merit or a fault.

"Dugu, you did it, you knocked the back of your head three times and activated the mechanism, but this time you did a really good job, hehehe......." Liu Chang gave Duguqing a thumbs up and said happily.

"Hey, oh, hehe, then I'm a success, a failure, a failure, and a failure, it's all my doing." Duguqing looked at the place where he had just sat and kowtowed on the back of his head, and patted his chest unashamedly, and a sense of relief that the capital crime had been exempted floated away.

"Time is pressing, let's hurry up and see what's going on inside."

Feng Daicheng reminded, and then took the lead in walking. Without further ado, the others all went in with Feng Daicheng.

Sure enough, when they reached the end, a huge storage room appeared in front of them.

Sun Mo was familiar with the road, found the oil lamp and lit it, and the storage room lit up.

"You guessed it, we didn't destroy all the medicines, this is the largest pharmacy stock." Feng Daicheng looked at Duguqing and said.

He looked at the bottles and cans on the shelves with some sadness. If these are not things that are used to harm people, what does it matter if my uncle stores more? But deliberately harming others, even if it is just a little, makes his conscience tormented.

"Then why don't we just destroy all of them to get rid of the trouble?" The leader of the Dark Guard said.

"No, this place may be much more useful than we thought, I know my uncle, the more secret he hides this place, it means that this place is definitely not only used by the King of Shu. That said, maybe we can use it too. ”

"Uncle?" Liu Chang didn't understand what his uncle had to do with this.

"The poison chief is his uncle." The leader of the dark guard solved Liu Chang's question.

"Oh...... Originally. Liu Chang didn't continue to ask more questions.

Dugu Qing secretly glanced at Feng Daicheng and found that his whole body tensed up when he heard the word poison head. It proves that the poison head is a hard existence for him to forget, especially the poison head died because of his "betrayal". Although the poisonous head died innocently and did not deserve sympathy, for Feng Daicheng, it was a painful ending for his relatives.

Facing the room full of medicines, none of them understood what they were for. Liu Chang, the only one who knows some pharmacological knowledge, is also confused, and he doesn't know how to start.

Suddenly, there seemed to be movement on the wall on the other side of the stone room, Liu Chang and the others glanced at each other and quickly blew out the oil lamp and retreated to the dark passage.

The others stepped back a little further, and the Dark Guard Leader had the advantage of being able to get close to his target without being noticed, so he leaned closer to hear what was going on.

Sure enough, a stone door opened, and more than a dozen people came in, only to hear the leader explain: "Quick, take away all the medicines on that shelf first, our Shu army was injured by their snatching of weapons, resulting in a large increase in wounded, and a large amount of antidote is needed." The rest is kept here in case of emergency. ”

All of his men moved quickly, and the leader himself ran to another shelf to find something. Finally, he took a large black bottle, opened it, smelled it, and put it in a cloth bag.

The dozen or so men finished what they were going to take and quickly left. When the leader of the secret guard informed Liu Chang that they were back at the pharmacy again, he told him everything he had heard and seen.

After listening to this, Feng Daicheng seemed to think of something, and walked to the empty shelf. He looked at the shelf next to him, and the color of the bottles on it and the medicine bottles that had been taken were white. He took a bottle from another shelf and poured out the pills inside, which were light red pills. Although he didn't understand, he had a bold guess.

"Maybe this is the antidote to being injured by poisonous weapons, the Qin army should have known that the weapons of the Shu army were poisonous, so they took their weapons and injured them. But the Shu army had an antidote, but the Qin army did not, so the Qin army was still at a disadvantage. ”

"yes, that's absolutely it, so we can't wait any longer. Regardless of whether this is an antidote or not, since it is needed by the Shu army, even if we don't use it, taking it all away will be a blow to them. Duguqing quickly came to a conclusion. Then, she said to Liu Chang: "Without further ado, you go and see how the door opens there, and we will go out directly from here." ”

Liu Chang was surprised, and hurriedly went to check, and a few people were left to pack the medicine bottles. But I found that it didn't work, there were too many medicine bottles, and a few of them couldn't take that many at once.

When everyone was in trouble, Sun Mo scratched his head and asked puzzledly: "Miss, these medicines are all one by one, and they are strong to the touch, why should we take the bottle away, pour it out directly, and find a cloth bag with each of us tied to our waists and go directly easily?" ”

"Hey, yes, I didn't think of that!!" Dugu Qing slapped his head, almost being stupid to death by himself, and found out that he was busy working for a long time. When Sun Mo said this, everything was simple, and she happily praised Sun Mo: "Well, it's not in vain to mess with me, you have grown a lot, and when you get out, I will reward you with a box of gold." ”

"What do I want gold, I follow Miss and I don't have to worry about food or clothing."

"It's for you to marry a wife and have children."

"I... I don't need it, besides, Miss usually gives a lot of tips, which is enough for me to spend a lifetime. Hearing that he should marry a wife and have children, Sun Mo blushed embarrassedly.

"Okay, let's go out and talk about this, hurry up, let's pour out all the medicine." After Duguqing finished speaking, everyone started to move.

"There are too many medicines, and ours are all small bags, I'm afraid there is not enough space." Feng Daicheng looked at the small bag that he had filled and said worriedly.

"That's not easy."

Duguqing took off her coat, spread it directly on the ground, and then poured all the medicine on her coat. Feng Daicheng frowned, he didn't quite agree with Duguqing's informality, but he didn't say anything, and helped pour out the medicine.

Liu Chang retreated listlessly and said: "This door can only be opened from the outside, and it can't be opened from the inside, and there is only a mechanism that locks the outside and doesn't let in from the inside." ”

When others heard Liu Chang say this, their originally passionate fighting spirit instantly lost their confidence.

"Oh, I see, so to speak, the passage here is a dead end and a living road. From the beginning, it was designed to meet the needs of the user, once they knew that someone had broken in, the user could shut down the mechanism from inside and prevent others from entering, but he himself had other ways to get out, and if it was okay, it would mean that all roads leading to Rome by themselves could enter and exit. ”

Duguqing suddenly brightened, and everyone felt that it made sense. But the question is, what should they do? Is it waiting for them to come in again to get their medicine and looking for a chance to go out?

"In this way, we have been blocked by two roads, the poison peak and the weapon pants are no longer passable, and the only thing left is the place to go to the Shu Palace, but it is estimated that the direction of the Shu Palace will not be able to get out." Thinking of the pile of ruins in the Shu Palace, Feng Daicheng began to despair a little.

"yes, it definitely doesn't work there." The leader of the Dark Guard nodded in agreement.

"Why, we haven't reached the end yet, how do you know if you can't get out?" Dugu Qing didn't react stupidly.

Another pair of eyes shot at Dugu Qing, she still didn't react, Sun Mo was more protective of the master, and reminded slightly: "Miss, didn't the Shu Palace turn you upside down?" Even if there is a passage, I am afraid that it will be destroyed, and it will not be able to get through. ”

"Uh...... That...... Like, it shouldn't work. Duguqing wrinkled his nose, a little embarrassed to pick up a stone and hit his own feet.

"Then it looks like we have to wait for someone to come in from here again before we have a chance to get out." The only way out that Feng Daicheng thought of was to wait.

"No, theoretically there should be a place to go out."

Liu Chang thought of another narrow passage in the dark river, which should also be an outlet, otherwise, how would the water get out?

"Where?"

“？？”

“？？”

“……”

Everyone looked at Liu Chang, as if they were pointing at him and leading them to escape. Liu Chang said his association with the water temperature of the dark river and the lake, but said with difficulty: "But I also investigated there, the water is out, but there seems to be no exit, but a closed mountain, I feel that as long as the mountain is opened, the outside must be the lake." ”

"Wouldn't it be nice to get through it." Dugu Qing looked relaxed again, and said that it was as easy to deal with as if the mountains there were mud.

Duguqing didn't care about their fuss, just now she noticed that there was a corner where several large jars of saltpeter powder were stored. This is a medicinal herb that can be used as medicine, and it can also be turned into explosives. In her other era, this thing could be obtained casually, and it may be a rare material here, so it was hidden here like a poison head.

Duguqing asked Sun Mo to dive under the only passage that Liu Chang said, and sure enough, as she expected, there is a gap under the dark river that can lead directly to the outside, but the water can go out, and people can't get through.

So Duguqing took local materials and divided those saltpeter powder into half-sized clay pots and sealed them, ready to do a big job and blow up a way to live.

Just in case, she first confirmed whether it was open as long as it was inside, and the mechanism could be turned on if she wanted to, and it would be turned off if she wanted to. After getting Liu Chang's assurance that it could be opened again, she simply asked Liu Chang to close it. If that doesn't work, come back and open the mechanism and wait for someone to come.

Although everyone didn't know what Duguqing wanted to do, but after seeing Duguqing's "ability to reach the sky" a few times, they could only shut up and listen to her command.

Duguqing asked them to move the saltpeter to the raft and fix it carefully, and then in order to cut the grass and eradicate the roots, she simply destroyed all the other unknown medicines in the pharmacy. Just take what you have to take.

Then, the raft full of saltpeter was asked to be rowed by the leader of the Dark Guard, who had achieved great skill, to row the raft to the end of the waterway, and then let the raft cling to the mountain. The clay pots are lined up, sprinkled with saltpeter powder connected to the saltpeter powder in the jars.

The leader of the dark guard is already experienced in following Dugu Qing's instructions to light the fire, after flying away from the raft, he wrapped himself around the stone pillar hanging down above his head, and then took out the fire fold and blew it, and threw it into the clay pot in the middle steadily, this time he didn't dare not listen, after lighting the fire, he flew to Dugu Qing's position.

Before he arrived at the place, there were several loud explosions on the side of the bombed mountain, almost the entire mountain shook, and the ripples of the dark river, which had almost no waves, were immediately stirred. Then the thick smell of smoke and gunpowder dissipated in the dark river and rushed towards them.

After waiting for a while, everything seemed to be calm again, and everyone went to see if the mountain had been blown through. At first, there was still smoke, and I couldn't see it clearly, but the further I went, the more light there became. In the end, their raft left the mountain and went outside.

After a few days of groping in the dark, they suddenly saw a light in front of them, and they suddenly covered their eyes a little uncomfortably, but the different air outside had made them so excited that they couldn't help themselves, and they all laughed, and they finally came out.
