Chapter 1176

Looking at people's expectation, Tang Feng said: "Xiao Hui said that the trace of the fire is very regular. At the edge of the fire, it's a very straight line, which clearly divides the burned part and the unburned part of the bamboo forest."

Xue Rui is very surprised again "ah", the complexion is extremely tangled, as if very want to not understand appearance, between the eyebrows wring.

He felt the stubble on his chin that he would have to shave off in the future, and said slowly: "this kind of situation sounds very strange. The fire is extremely uncontrollable. How can it burn to a certain position and then go out? There must be something unexplainable! Mr. Tang, do you think it has something to do with the sect of practice? They did it by special means? "

Xue Panpan also nodded slightly, puzzled, and said, "but what's the purpose of what they do?"

When Li Jianming saw how Xue's sister and brother looked, he couldn't help laughing and said, "Miss Xue, master Xue, this matter is not as complicated as you think. It's quite easy to do this."

"Easy?" Xue Rui stares at Li Jianming in an incredible way.

In his view, it is inconceivable that the fire can be controlled and put out when it burns to a certain place.

If Tang Feng said it was simple, he would not feel anything. But Li Jianming was the one with the lowest accomplishments among all the people present. It was incredible that he said such a thing.

Li Jianming nodded and said with a smile: "young master Xue usually lives in the city. Even if he occasionally goes to the countryside, he must not be in such a big mountain. It's normal not to know such things as burning mountains and opening up wasteland."

"Burning mountains to open up wasteland?" Xue Rui repeated these four words, and his face became more and more puzzled.

Rong Guocheng has understood Li Jianming's meaning and smiles.

At the moment, Lin Mengjia and Xue Panpan said in one voice: "what's that?"

It can be seen that these young ladies or young men from big families are totally ignorant of such things.

Li Jianming explained with a smile: "in the history of Huaxia, agriculture has always been the mainstay. This agricultural country naturally needs a large area of cultivated land as the basis. However, in the course of historical changes, the vast majority of land is concentrated in the hands of a few ruling classes. People without land will think of some ways to obtain land, which is to burn mountains and open up wasteland, That's one of them. "

Xue Panpan said, "is it to burn the trees on the mountain, and then plant the land on the mountain?"

Li Jianming nodded and said, "Miss Xue is really smart. That's right. Although the land in the mountain is owned by the ruler, because it is not registered as cultivated land, the harvest planted on the reclaimed land does not need to be taxed. Many people come to the barren mountain and burn down the original forest at the risk, There are a lot of mineral elements in the burned plant ash, which is very good for the growth of plants. Therefore, the crops planted by burning mountains to open up wasteland were quite good in Chengdu a few years ago, and many people flocked to it. "

Although Xue Rui listened to Li Jianming's words, he was still puzzled and said, "is this good mountain forest burned like this? I think many trees have grown for many years. It's a pity to burn them up with a fire. Besides, you said the harvest was good in the past few years. Can't you do it after that? "

Li Jianming nodded his head with a look of regret on his face, and said: "in the first few years, the soil nutrients were relatively sufficient. The ancients naturally did not have all kinds of chemical fertilizers as they do now. Once the soil nutrients were insufficient, they would give up and go to other places to look for barren mountains and reclaim wasteland. This is not uncommon in history. Burning one land, planting one land, and changing one land."

Lin Mengjia could not help exclaiming: "so many mountains and forests have been destroyed in vain? Is there no one in charge? "

Rong Guocheng said: "now it's natural that someone is in charge of it. The laws of Huaxia state prohibit burning mountains and reclaiming wasteland."

Xie tiger also nodded his head and said: "yes, now the government is to prevent the spread of mountain fires, protect the environment and reduce air pollution. It is better to manage mountain burning, which has been completely eliminated in recent years."

Li Jianming went on to say: "although no one has done this in recent years, in history, burning mountains and reclaiming wasteland emerge in endlessly, and people are also quite experienced. At that time, people knew that once the mountain fire could not be controlled, it would burn all over the mountains and fields. In practice, many experiences have been summed up, and controlling the spread of the fire is one of them."

Hearing this, Xue Panpan asked curiously, "what's the way?"

"The reason why the fire spread is that there are objects to support the fire. Trees in the mountains are like this. Under normal conditions, before burning the mountain, a deep gap is dug along the land. There is nothing to burn in the deep ditch, and the fire will naturally stop here."

Li Jianming smiles. He is from an ordinary family. When he was young, his family was in the countryside. Naturally, he knows quite well about these things.

Hearing what Li Jianming said, Xue ruicai suddenly realized, but he still had a little doubt and hesitated: "in this way, if you want to leave a straight trace, just dig a ditch?"

The answer is too simple, which makes Xue Rui feel incredible.

Li Jianming nodded with a smile and said, "when I first heard it, I thought it was incredible. I thought the fire would burn as much as I wanted. How could it be blocked by a ditch? Later, when I saw it with my own eyes, I believed it was true. Don't get me wrong. What I saw was not burning mountains, but farmers burning straw in the fields. "

Hearing the words "burn straw", Lin Mengjia and Xue's brothers and sisters showed some curiosity on their faces.

After all, for them, these are completely unheard of, inevitably will feel interested.

In order to prevent them from further entanglement on this issue, Tang Feng coughed softly and said: "it is because the scope of the fire can be controlled and the way is not too difficult that I suspect that it was deliberately done. I just doubt the time of the fire, that is, let Xiao Hui go back there, Collect some burnt ashes and other things and show them to me for further consideration. "
