Hu Yanjin covered his mouth and nose and shouted: Master, what is that?

It just so happened that Zhang Yue also ran in. The light of the torches was not very clear in the past, but there was a flash in the water.

Hua Youcai said: "That's a person, it has been corroded, and only the wreckage remains." There is gold in the water, and gold does not corrode. This person should have gone in before going down, hiding and not leaving, wanting to get some gold before leaving, but who knew that he couldn't get out. ”

Seeing the gold ingot, Hua Youcai also roughly estimated the depth of the pool.

The three left in a hurry.

"Let's go, everybody get out."

"What? Be...... Can't get in? The master of Long Xiaozhai hurriedly asked.

"The pond in front of it fills the entire passage, and it is not practical to build a wooden bridge, and the span is too large...... Get out there and figure it out. ”

Hua Youcai just wanted to go out, Lan Xi suddenly whispered to Zhang Yue:

"I feel like there's someone in the back."

Hu Yanjin also heard it, he looked around and saw the firelight flickering on the stone wall, this was the first entry of the stone gate, probably not far from the exit, the torch was burning very happily, and even the smell of water wafting out of it quickly faded.

Just now I was thinking about how to walk inside, but I didn't pay attention to it, the top of the cave when I first came in was relatively high, and the top of the cave that went through the magnet door and walked in was obviously much lower.

Could it be that the hole inside was carved out by hand? Yi Chengjin came here with treasure, this is an accidental event, why would someone work so hard here to make a secret hole with many mechanisms?

Lan Xi said that there is someone behind, is it the owner of this hole?

Who are they?

"Let's go, go out with the master and figure out a way." Hu Yanjin patted Hua Rong on the shoulder, walked two steps quickly, and walked in front of Hua Youcai.

Zhang Yue returned to the magnet door, pulled his knife down, and quickly left the magnet door.

Out of the hole, they suddenly felt that the world was so beautiful, and everyone couldn't help but take two deep breaths.

The second child said: "Just now, I also felt that someone had been following us, nine times out of ten, it was the owner of this cave. ”

"You are in Lingshan, haven't you heard that there are strange people living in the back mountain before?" Hu Yanjin now felt that he should go to find the owner of the cave first.

The owner of Long Xiaozhai thought for a while and said: "Further down this valley, there is a village, I don't know which county it is under the jurisdiction of, there are only thirty or fifty households, and we never rob them. ”

"That's because you rabbits don't eat the grass next to the nest, for fear of attracting officers and soldiers to take your cottage!" Zhang Yue said with a smile.

"There's nothing to be ashamed of, our village has been safe and sound from the Yuan Dynasty to the present, relying on ...... Is it enough to eat? The owner of Long Xiaozhai said unashamedly:

"So, we have a better relationship with Houshan. My father told me that there are indeed strange people living in the back mountain. They opened an ironsmith shop in the village, and the craftsmanship was indeed good. ”

"Then why do you say 'strange people'?"

"They seem to be masters and apprentices, and they rarely communicate with others, but the agricultural tools and iron tools they make are very delicate and practical, and those who are honest take very little, and those who are poor do not take anything. Is this a strange person? ”

Hua Youcai asked him: "Did the owner of the village say that the mechanism in the cave was also made by them?" ”

"This ...... I'm not sure. However, who else but them will have nothing to toss the strong water and weak water, wait for the rabbit, and wait for someone to bring the treasure in? ”

In addition to the two dissenting subordinates of the cottage this time, the master of Long Xiaozhai was also in a good mood, and he asked Hua Youcai: "Mr. Song just said that he wanted to find a way, I don't know if there is any way to get in?" ”

"There are many ways to do it, depending on which one is more convenient. The owner of the small village, can there be a lime kiln that burns lime nearby? ”

"It's all mountains, and of course there are lime kilns! Sir need lime? ”

Hua Youcai nodded and said: "Yes, I saw it just now, the depth of alum oil is up to the calf, if it is made of wood, it can also be used, but it will always be threatened by alum oil, and if you don't pay attention to it, you will burn your skin."

It's better to find some lime and neutralize it with alum oil, and when they turn into gypsum, it will not be corrosive. ”

The owner of Long Xiaozhai patted his thigh and said: "We can do our best, or it will seem that our Changlingzhai eats white food!" ”

"Master, do you mean pouring lime directly into the pool? What else do I need to prepare? ”

"It's better for people not to go in because when the two react, they produce carbon dioxide."

Hua Qiao hurriedly asked, "Daddy, is that poisonous gas?" ”

"When you breathe, you exhale carbon dioxide, although it is not poisonous gas, but the space inside is small, and suddenly a lot of people exhale at you, you can't breathe in oxygen, and you don't suffocate?"

Hua Youcai's thirty years of experience in Daming told him, don't think that if you don't understand the Ming people, you won't dare to say it.

In modern science, they are like a blank slate, and the obvious common sense, even if it is a term they have not seen, you just have to tell them that they will understand and remember it in their own way.

This is how he was when he taught buckwheat, and he felt that he was very successful.

"Is there a bamboo nearby?" Hu Yanjin asked: "I have seen the use of bamboo troughs to lead water to the waterwheel, can we use bamboo to send lime slurry from the outside into the inner pool?" ”

"Maozhu has it! There are many growing near the village. The sixth child called: "When I go back and tie my belt, I will take someone to cut bamboo!" ”

To manpower, there is a place in Changling Village, before dark, everyone set up a bamboo frame, high on the outside and low on the inside, and the lime milk flows down the bamboo trough to the hole. Hearing that the gas generated is not poisonous, the owner of Long Xiaozhai plans to go in and take a look.

Hua Youcai smiled and pointed to the cave, it was already pitch black, and the torches he had lit before had all been extinguished due to lack of oxygen.

"At this rate, we'll go in tomorrow morning, just right. Everyone hurry up and rest, tomorrow after the pool of, what mechanism is waiting for you. ”

In the shadows, those eyes closed and only murmured, "Lime slurry neutralizes...... Carbon dioxide...... Oxygen...... What is that? Could it be that he is a wizard? It's not like that! ”

Someone brought pickles, rice, and water, and everyone didn't want to go back, so they lit a fire near the entrance of the cave to keep warm, and sat by the fire to rest.

"I really didn't expect that Yi Chengjin would die even if he died, and he would have to give us so much trouble."

Zhang Yue used a long wooden stick to gently pluck the firewood, and Lan Xi sat beside him, his head tilted, leaning on his shoulder.

Hu Yanjin shook his head and said:

"It's all up to this senior, so that he can't get these treasures, so he is forced to use the Han King to do it, otherwise, let him lie dormant for another three or two years, use these treasures as military funds, and garrison troops or buy and transform troops in various parts of the Ming Dynasty. The consequences would be unimaginable. ”

"That's right, although there have been small riots in recent years, the Ming Dynasty is generally stable, and the people's lives are richer than they were 25 years ago. Huyan, it is obviously the money of the Song Emperor, why do you say 'take it from the people and use it for the people'? ”

Zhang Yue still felt in his heart that such a large amount of wealth should be used to enrich the treasury of the Ming Dynasty.

Hua Youcai said with a smile: "For thousands of years in China, the money of the Song Emperor was not exploited from the ancestors of the Ming people?"

The hole in the Ming Dynasty is too big, just this money, the emperor has spent two Zhu batches, it is better for us to use it in an immediate place. ”

He hesitated for a moment, and said: "I watched the stars at night, and found that in a few years, there will be several consecutive years of drought in this dynasty, and after the great drought, the locust plague will start, and by that time, I don't know how many people will starve to death in the north and south of the river." ”

Everyone was speechless in shock.

Hu Yanjin sighed secretly: No wonder the emperor said that even if the master didn't say anything bad about him, he couldn't be kept. The master casually looked at the astrology and met a Taoist priest, and what he said was sensational!

He counted on his fingers again, no, the second child may have just been born at that time, and he had to stock up on some food.
