When Li Tangshan and Panli hugged each other in the kitchen, the hatred outside the kitchen had reached its highest. The senior brother, the second senior brother, and the third senior brother were scolded by the master outside, and Nan Xinghan also let them build a pool.

Senior brother, what do they know how to build a pool so that it is convenient? So they all came to Li Tangshan to ask Li Tangshan, how to repair the pool and canal? Li Tangshan also took the opportunity to extort them, and each of them used a good kung fu to exchange it with Li Tangshan.

Li Tangshan used his hearsay to talk about modern water conservancy knowledge to the three senior brothers, and Li Tangshan calculated that if the front of the entire water diversion project was stretched a little longer and longer, the more benefits Li Tangshan would be able to gain from the senior brothers.

Under Li Tangshan's careful layout, the first large-scale construction of the division in hundreds of years kicked off.

Li Tangshan explained to the senior brothers and sisters: "Senior brother, second senior brother, we have a problem with the aqueduct now, that is, whenever it rains, the rainwater will enter the canal, and our spring water will become very mixed and cannot be used at all. So we're going to build a closed well in the water source now, so that when it rains, flash floods won't go in. Or the fourth senior sister, you are responsible for burning some charcoal, and when the well of the senior brother and the second senior brother is built, we will put the charcoal into the well, and use it to filter the water quality, so that it will be very delicious. Third Senior Brother, you are responsible for repairing all our water canals and culverts. I went to find out if we could renovate the flat land of the paddy fields near Shimen, so that after we could grow food, we would not have to go down the mountain to buy food, and everyone would be able to live a life of abundant food and clothing. ”

Li Tangshan glanced at everyone: "Do you have any other questions?" If not, please take your place and do it. Fourth Senior Sister, wait a minute! Your charcoal can't be burned casually, so I'll tell you the key to charcoal burning in a moment. ”

Senior Sister Panli felt more and more that this little junior brother knew a lot more than any of them, and the third senior brother used to think that he was more knowledgeable, but compared to Lao Wu, it was far behind, and Li Tangshan had increased a lot in the senior sister's heart.

Li Tangshan pulled Pan Li back to the master and explained to him: "Senior sister, first of all, let's make a carbonization furnace kiln, and the joints around it should be tight. No air leakage, if there is gas leakage in the carbonization furnace, the amount of oxygen entering the furnace cannot be controlled. The burner in the furnace is easy to spontaneously combust excessively, so that the carbonization temperature rises too quickly, so that the charcoal fired is loose and easy to break. Worse still, excess oxygen can cause some of the sticks to burn into a white powder (ash), resulting in a decrease in charcoal production. ”

Panli shook his head: "Senior brother, I don't seem to understand, can you explain it again?" ”

Li Tangshan didn't know how to explain the scientific principle to this little sister for a while: "In short, the carbon structure is hard, the carbon surface is smooth, the cracks are few, and the proportion is heavy, so the carbon is good carbon." ”

Panli nodded and looked at Li Tangshan with adoring eyes: "Senior brother, why do you have so many things in your little brain?" How do you know so much? ”

Li Tangshan admired herself even more for this little girl in her heart, and it seemed that it was better to beat herself a lot less. Li Tangshan continued: "The change in the color and quantity of smoke coming out of the carbonization furnace can reflect the carbonization of the burner in the furnace, and the change of the color and quantity of the artificial smoke is divided into three stages. ”

"1. Ignition and further drying stage of the rod, that is, the furnace temperature is below 150 °C, and the amount of smoke coming out of the furnace chimney is large and black. If a carbonization furnace with a tar cooling device is used, the color of the smoke is lighter than the former. If an environmentally friendly carbonization furnace is used, the flue gas generated can be recovered and disposed of.

2. In the pre-decomposition stage, that is, the furnace temperature is between 150 °C and 270 °C, the smoke volume is slightly smaller than the former, and the smoke color is light yellow.

3. In the decomposition stage, that is, the furnace temperature is between 270 °C and 400 °C, the smoke is whitish, and the amount gradually decreases and thins.

If the amount of smoke is scarce, almost nothing, and the color is blue and translucent, it means that the carbonization is over. At this time, the fire can be "closed", and the charcoal can be released after cooling. ”

Li Tangshan explained in detail.

Li Tangshan looked at the affectionate eyes of the fourth senior sister who admired him so much: "Senior sister, do you understand?" ”

Panli shook his head and said, "I don't understand, I don't understand how you can understand so much." ”

Li Tangshan gently held up the fourth senior sister's face with his hand, and then gently kissed her on the forehead. The fourth senior sister did not refuse Li Tangshan, but enjoyed this feeling very much, if Li Tangshan had done this action before, she would definitely have been flattened by her.

Li Tangshan asked Pan Li: "Senior sister, are you free tonight?" I want to go with me to the top of Fanjing Mountain to watch the sunrise. Then I'll be waiting for you at the top of the mountain tonight. ”

Pan Li nodded.

Li Tangshan was very happy, thinking that he had finally soaked his senior sister after working hard for so long, his heart was like drinking honey, Li Tangshan felt that everything he watched today was very pleasing to the eye!

Li Tangshan waited for a long time until it was dark, but there was still a long time when it was dark, Li Tangshan was completely sleepy, and climbed to the top of Fanjing Mountain before he arrived, and there was no building in Fanjing Mountain at this time. Li Tangshan found that this was a good place to cultivate, anyway, it was still very early, so he tried to practice and teach the Mo family's internal exercises. I don't know how long it took, Li Tangshan could feel someone coming up from the top of the mountain. Li Tangshan was overjoyed to find that his sensing ability was slowly recovering, which was a good phenomenon.

climbed away from Lao Yuan and called Li Tangshan: "Senior brother, you came so early?" You're here to cultivate? ”

Li Tangshan saw that he was still so beautiful under the moonlight, and was about to call the fourth senior sister. The voice of the third senior brother came from behind: "Senior sister, what are you doing when you asked us to come to this wilderness so late?" ”

Li Tangshan's mood fell from heaven to hell, and he said in his heart: "Senior sister, do you know what dating is?" What are you doing with a light bulb? ”

There were also voices from the senior brother and the second senior brother in the back: "Old Wu, why did you arrive so early!" ”

Li Tangshan saw that there was not only one light bulb but also three, so he had to stiffen his face and say, "I see that the cultivation in this place is good, so I will come to breathe in the aura." ”

Li Tangshan scolded in his heart: "Senior sister, you bring three electric light cannons here, how can we cultivate feelings." ”

Panli felt that Li Tangshan was a little displeased: "Senior brother, it's so dark that I can't see the road clearly, I'm scared, so I called all the senior brothers." ”

Li Tangshan smiled bitterly in his heart and thought: "It seems that I, Li Tangshan, have not thought carefully enough. He quickly shook his head and said it didn't matter.

The third senior brother even pulled the fourth senior sister's hand too much, and Li Tangshan was so angry that he was about to explode.

The nerd of the senior brother began to talk about the ancients again: "Sure enough, as the book says, the sky glows into the water, and the sky in the water is red for a while. Watching the sunrise from the top of the mountain is really a different feeling. Thank you for the invitation. ”

The second senior brother, the stone man, saw the snow-white clouds rolling in the air like ocean waves, colliding, and crowding. He lived at this time for decades, and never thought that the sunrise from the top of Fanjing Mountain was so beautiful.

Looking out from the top platform, as far as the eye can see, there is a vast sea of clouds. The red sun has not yet risen, and a few rays of morning glow in the distance have dyed the east red. In the blink of an eye, a red dot appeared at the junction of the sea and the sky, gradually becoming larger and rounder, and under the background of the boundless sea of clouds, it was quite beautiful. Finally, the vivid sun jumped out of the "sea", and the sun shone on the earth.
