Steamed buns, go farming with your mother

Chapter 229
Su Ho breathed a sigh of relief, fortunately he was cautious for a while, otherwise he entered the cave rashly, and he didn't know what would happen.Many of these hidden guards had already lost their lives because they were protecting their own safety. She didn't want them to die for her again under such circumstances.

After thinking about it, Su Ho felt that this matter should be explained to Zheng Dongxu, and he said, "Brother Zheng, we have to wait a while, this cave is not ventilated all year round, and there is no oxygen in it, so people will definitely be relieved if they go in like this! Without checking for a while, Su Ho said the word oxygen.

Although Zheng Dongxu didn't know what oxygen was, he thought it must be a very important thing, so he nodded and didn't ask any more questions, but An San was very curious. His specialty was the investigation of the cause of death. Su Ho said that this is obvious. It is something that kills people, so he couldn't help asking:
"Girl, what is oxygen?"

Su Ho was stunned for a while, but Zheng Dongxu listened intently, because he believed in Su Ho, he didn't feel the need to ask some questions, but if someone asked, he didn't mind listening to them.

Seeing An San with surprise and longing in his eyes, Su Ho didn't know how to explain it. After going through all the things about oxygen in his mind twice, he said slowly: "I know that people don't eat or drink water. How long can you live?"

An San was stunned for a moment, but after all he often dealt with dead people, he thought for a while and said: "I should be able to live for five or six days without food, and I should live longer without water, and maybe eight or nine days..." Always Confidently, when he said this, he felt very guilty, and made up his mind to learn this knowledge when he had time.

"No," Su Ho shook his head and said, "If a person does not eat but drinks water, he will die within seven days at most. day will die!"

Zheng Dongxu looked at Su Ho in surprise, but he didn't know that Su Ho knew this. The more he got along with Su Ho, the more he felt that Su Ho was an extremely fascinating book. Once he opened the first page, I couldn't help but continue to read, no one knows how thick this book is.

At this moment, he felt that he was very lucky to be able to discover this book early, and before others had time to react, he hugged this book in his arms.

An San looked at Su Ho with some admiration. He had never heard of these things. No wonder his master couldn't move when he saw the girl. This was the reason.

Naturally, Su Ho didn't know that a piece of common sense from the 21st century made her unknowingly subdue a general under Zheng Dongxu's command. Of course, she just laughed it off when she knew about Su Ho.

Continuing to talk about the topic of "oxygen", Su Ho was actually very embarrassed, because she didn't know how to explain it, she didn't want to be careless, and today was spent in "class".

"Oxygen is actually a kind of thing in the air, and the air is just these!" Su Ho waved his hand, and the movement of the air drove the flow of air, making Zheng Dongxu and An San feel the wind.

In fact, when Su Ho did this, Zheng Dongxu and An San became even more confused, but Su Ho's next explanation made them understand a little bit.

"Air is actually the colorless and odorless gas around us. For example, when I just fanned my sleeves, the wind you feel is air flowing. Oxygen is a part of the air, but for us, this part is But it is very important!" Su Ho emphasized here: "Generally speaking, without water, a person can live up to three days, but without air, the best breath-holding master can only live for half an hour. , what we breathe in is oxygen, but what we exhale is carbon dioxide.”

"Just now I said that there is no oxygen in the cave because it has not been ventilated for a long time. Conversely, it is full of carbon dioxide, because oxygen is not as light as carbon dioxide. Under such a closed environment, carbon dioxide slowly precipitates, while oxygen is due to It is light in weight and is slowly squeezed out by carbon dioxide."

Speaking of this, An San suddenly realized, and exclaimed: "I said why some places seem to be safe, but the brothers died inexplicably after entering, so it is like this!" Then he said Looking at Su Ho with thirsty eyes, he said, "Girl, what should I do to save the lives of my brothers?"

Su Ho shook his head and said: "There is no good way to do this. Generally speaking, the only way is to wait. I just threw a torch in, just to make sure there is no oxygen in it. When the environment in that place is no longer airtight, The flow of air will drive the carbon dioxide to live, and then it can go in!"

While speaking, Su Ho signaled the guards to throw a torch in again, but unfortunately, the torch was thrown out within half a cup of tea before it was extinguished again.

Su Ho breathed a sigh of relief, and said, "In about half a quarter of an hour, everyone will be able to go in!"

Zheng Dongxu nodded to show that he understood, and then waved his hand. The people under him are naturally busy. They are all the most elite people, and they are familiar with doing these things, but today they added Su He and Zheng Dongxu, so prepare Just a little more work.

After waiting for a quarter of an hour, Su Ho asked another torch to be thrown in. This time, the torch was brightly lit for a long time, and Su Ho said, "It's done!"

An San looked at Zheng Dongxu, waiting for Zheng Dongxu to give orders. Seeing Zheng Dongxu nodded and whistled, the hidden guards filed into the cave.

Su Ho and Zheng Dongxu followed behind.

This cave looks inconspicuous, but after entering the cave, I found that the inside of the cave is actually very spacious. It is a round hall of about ten feet. In the place of the passage, there are several caves that lead to unknown directions, and there are faint fires coming from inside, Su Ho knew that the hidden guards had already been the first to investigate.

Next to the passage, there is a table that looks old. I don't know if it is because the air is not circulating here, so the table seems to be well preserved.It's just that the trees on the mountain were cut down and a random picture was made. It doesn't look very delicate. At most, it stands firm and feels flat. The table is covered with a thick layer of dust.

The strange thing is that even though this table is very inconspicuous, it is in the corner of the table, but there are four treasures of study, such as pen, ink, paper and inkstone. Things shouldn't appear in a closed cave.

The paper has turned yellow, showing that it has been here for a long time. Su Ho shook off the dust on the top piece of paper, and softly got up. Looking closely, there were still some dots on the paper. Ink blots, stained on the rice paper underneath when writing regularly.After careful identification, there are a few characters that I can still recognize.

Passed it to Zheng Dongxu, and Su Ho continued to arrive. There was a chair behind the table. Unlike the roughness of the table, the chair in this chapter was obviously carefully crafted. It is not a good pear wood. The carver It can be regarded as fine, but it is obviously inappropriate to put it here.There is also a futon on the chair. Even after so many years, it can be seen that people often sit here.

There are some tools on the side of the hall, which are not difficult to find, but they are dustpans, catalpa shovels, hammers, lifting poles and other things. They are placed in a mess, but they are divided into areas, which still look a little neat.

On the other side, Zheng Dongxu studied the piece of paper, and found that there was something like an account book written on the paper, but he remembered that it was "June [-]th", "Dan Shi" and other things, which were a little unclear. And it's not neat, but the inscription at the end is very clear: Chen Erqi.

Passing the paper to An San, Zheng Dongxu said: "Give him to An Er, and let him find out who this Chen Erqi is, whether he is still alive, what relatives he has, and who he is in contact with on weekdays!"

Looking at the unknown date of this chapter, although An San bowed to answer, he felt a little gloating in his heart, as if he saw An Er's bitter face, but who would dare to say no to the master's order?

At this moment, a hidden guard rushed out of a passage, knelt in front of Zheng Dongxu, and said loudly: "I tell the master, there is a discovery ahead!"

Zheng Dongxu nodded, and the man stepped back, looked at Su Ho, and said, "He'er, do you want to take a look?"

Su Ho looked at the passage, thinking that there should be no danger, so he nodded in agreement, but let Zheng Dongxu walk in front.

A few people went to that passage, turned a few corners, and saw two hidden guards standing there with torches, apparently waiting there, a few people walked in, the two hidden guards saluted, but did not leave .

No need for the hidden guards to say anything, Zheng Dongxu and Su Ho knew what the hidden guards found: on the dug-out wall, there were a few shiny silver objects, each about the size of a fist, and the color was a bit gray , but it still sounds dazzling under the light of the torch.

Although he didn't know what it was, Su Ho could still guess that these things were probably what Chen Wenwen and Wang Song painstakingly wanted to hide.

But Zheng Dongxu's eyes flashed with surprise. Su Ho may not know what it is, but Zheng Dongxu is not ignorant since he was a child. He has seen this thing before, but he is not sure.

The hidden guards stretched out their hands to dig out a piece, Zheng Dongxu played with it carefully in his hands, and finally confirmed that this is silver ore, and it is a silver ore with a particularly high purity.

This made Zheng Dongxu understand something.

　Oh, and one more.
