Looking at everyone's expectation, Tang Feng said slowly: "Xiao Hui said that the traces of fire are very regular. At the edge of the fire extinguishing, there is an extremely straight line, which clearly divides the burning part of the bamboo forest from the unburned part."

Xue Rui said "ah" again in surprise, his face was extremely entangled, as if he couldn't figure it out, and his eyebrows were furrowed.

He touched the stubble on his chin that had not been scraped off with his hand, and said slowly: "This situation sounds very supernatural. The fire is extremely uncontrollable. How can it burn to a certain position and then extinguish it?

There must be something unexplainable among them! Mr. Tang, do you think this is related to the sect that practices, and it was only after they used special means?"

Xue Panpan also nodded slightly, looking puzzled, and said, "But what is the purpose of their doing this?"

Seeing the appearance of the Xue siblings, Li Jianming couldn't help but smile and said, "Miss Xue, Master Xue, this matter is not as complicated as you think. It is quite easy to do this."

"easy?"

Xue Rui widened his eyes and looked at Li Jianming incredibly.

In his opinion, it is simply unimaginable to be able to control the fire and let it be extinguished when it burns to a certain place.

If Tang Feng said that this matter was simple, he would not think anything, but Li Jianming was the lowest among everyone present, and he said such words, which naturally made Xue Rui unbelievable.

Li Jianming nodded and said with a smile: "Young Master Xue lives in the city on weekdays. Even if he occasionally goes to the countryside, he will definitely not be in such a mountain. It is normal for him to burn mountains and clear up land."

"Burn mountains and clear the land?"

Xue Rui repeated these four words, and his face became more and more confused.

Rong Guocheng already understood what Li Jianming meant and smiled slightly.

Lin Mengjia and Xue Panpan also said in unison: "What is that?"

It can be seen that the daughters and young masters from such big families are completely unaware of this kind of thing.

Li Jianming explained with a smile: "In the history of China, agriculture has always been the main focus. This agricultural country naturally needs a large area of ​​arable land as the basis. However, in the historical changes, most of the land is concentrated in the hands of a few ruling classes. People without land will think of some ways to obtain land. Burning mountains and clearing up wasteland is one of the means."

Xue Panpan said with a slight understanding: "Is it just to burn the trees on the mountain and then farm the land on this mountain?"

Li Jianming nodded and said, "Miss Xue is indeed smart. This is why the land in the mountains is owned by the rulers, but because it is not registered as arable land, the harvest planted on this land is not taxable. Many people take risks to come to this barren mountain, set a fire, and burn the original forest. The burned ash contains a large amount of mineral elements, which is very good for plant growth. Therefore, the harvest of the crops planted in the mountains was quite good in the past few years, and it has attracted a lot of people."

Although Xue Rui heard Li Jianming say this, he still had a little puzzled look on his face and said, "This beautiful forest is just burning it like this?"

I think many trees have grown for many years, and it is a pity to burn them all out with a fire. And you said that the harvest in the past few years is good, will it not work after that?"

Li Jianming nodded, with a look of regret on his face, saying, "The land was relatively nutritious in the past few years. Naturally, the ancients would not have had all kinds of fertilizers as they do now. Once the land was insufficient, they would give up and look for barren mountains to clear the land. This is not uncommon in history. Burn a land, plant a land, and change it."

Lin Mengjia couldn't help but exclaim: "So many mountains and forests are destroyed in vain?"

Isn't anyone care?"

Rong Guocheng said: "Now, there are naturally some people who control it. The laws of China are explicitly prohibited for burning mountains and clearing land."

Xie Laohu also nodded and said, "Yes, now the official is to prevent wildfires from spreading, and to protect the environment and reduce air pollution. It is better to manage things like burning mountains, and has been completely eliminated in recent years."

Li Jianming continued: "Although no one has done this in recent years, in history, burning mountains and clearing land has emerged one after another, and people are quite experienced. At that time, people also knew that once the wildfire could not be controlled, it would burn all over the mountains and fields. Many experiences have been summarized in practice, and controlling the spread of fire is one of them."

When Xue Panpan heard this, he asked curiously: "Is there any way?"

"The reason why the fire spreads is because of the objects that help burn, the trees in the mountains. Under normal circumstances, before burning the mountain, a deep gap was dug along the boundary of the land. There was nothing to burn in this deep trench, and the fire naturally stopped when it burned here."

Li Jianming smiled slightly. He was born in an ordinary family. When he was young, his family was in the countryside, so he was naturally quite clear about these things.

After hearing Li Jianming say this, Xue Rui suddenly realized it, but hesitated, "In this way, if you want to leave a straight trace, just dig a ditch?"

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

Li Jianming nodded with a smile and said, "When I first heard this, I felt incredible. I thought the fire would burn whatever I wanted. How could it be blocked by a ditch?

Later, I saw it with my own eyes and believed that it was true. Don’t get me wrong. What I saw was not burning mountains, but farmers burning straw in the fields.”

Hearing the three words "burning straw", Lin Mengjia and the Xue family siblings showed a curious expression on their faces.

After all, for them, these are things they have never heard of, and they will inevitably be interested.
