The next day.

As soon as it was dawn, Lin Bei got up and prepared to take a bath in Longtan.

It seemed to be quiet, Lin Bei felt a little unaccustomed, then looked up, looked at the bird's nest on the vine, and suddenly realized in his heart, it turned out that there was no cry of Diu and Qiqi, and the two little guys should also wake up at this time.

Lin Bei climbed up the locust tree and looked, the bird's nest was cold, obviously the two little guys didn't come back last night, Lin Bei was silent, his mood was complicated, some relief and some loss, the two little birds finally grew up and began to leave Lin Bei's shelter, and I don't know if they will come back.

Then Lin Bei remembered the little jackal with the birthmark, this little guy probably had already forgotten about Lin Bei, Lin Bei smiled dumbly and sank to the bottom of Longtan, everyone was a passerby, including these animals.

Cui Lan and the others woke up one after another, and began to wash with spring water, it was no longer strange for Lin Bei to stay under the waterhole, Cui Lan washed her face while still reciting the words that Lin Bei taught her yesterday.

As long as there is time at night these days, Lin Bei will teach Cui Lan to read some words, and Bian Ji will also watch from the side, Cui Alan's was illiterate before, but because he is illiterate, he has made rapid progress in knowing Lin Beijiao, after all, adults are much more receptive than children.

When the time is almost up, everyone gathers and heads to the school, today's main task is still to go to the Elephant Valley to catch elephants, Bian Ji and Zhen Ding naturally don't go, but Bian Ji will go to the school every day to take a look and understand the progress.

When they arrived at the school, the people hadn't arrived yet, Lin Bei went outside to catch two hares, came back and handed them to Cui Lan, and started to barbecue with the things left by the villagers, and waited for others by the way.

Bian Ji was a little drunk from drinking Meiya wine last night, and he was quite dizzy today, Cui Lan made some broth for Bian Ji, and drank the hot broth, and Bian Fuzi was refreshed all of a sudden.

"My lord, there is already frost falling." Cui Lan spoke, but her hand didn't stop.

Lin Bei nodded, it is true, it is a little cold at night now, and when you get up in the morning, you can see a layer of white mist on the leaves, of course, the weather is still very hot during the day, but you can know that it is very close to winter.

"This year, they are all in the academy, if it is winter, have the villagers saved food?" Bian Ji asked.

Cui Lan smiled: "It's okay, the academy is not hungry for anyone, I think some people still have meat." ”

"That's right, these people eat every day, and they eat meat, and I'm afraid there are many people who think that this matter can continue forever." Bian Ji laughed.

Zhen Ding also said: "In the past few days, there have been villagers selling mountain goods to our firm, all of which are hares and pheasants, which should be exchanged for locusts some time ago. ”

Lin Bei was speechless, come a few more times, then pull it down, a few more times Lin Bei will cry to death, but after the school is repaired, Lin Bei is ready to let the villagers raise rabbits and pheasants, and it will be fine when it comes to slaughter.

A few people talked and laughed, time passed quickly, and finally, the people could be seen coming over in the distance, and it was An Zhongzhi who walked in front.

Seeing Lin Bei, An Zhongzhi's face lit up, but he didn't forget his own work, first instructed the little officials to let the people do things, and he quickly ran to Lin Bei and looked at Lin Bei with a bitter face.

"How?" Lin Bei asked strangely.

"My lord, it's the proboscis beast."

"But what's wrong?" Lin Bei's heart tightened.

"No, it's just that the proboscis eats too much." An Zhongzhi smiled bitterly: "Yesterday, I ate an ox cart just for grass grain, about two hundred catties, which is the ration of dozens of days of ploughing cattle, my lord, you see"

Lin Bei smiled, it's normal for elephants to eat too much, if they eat less, people will worry about whether they are sick, "Then today you can let people lead the proboscis beast to eat near the mountains?" ”

"Naturally, there are about dozens of people following them, just for fear that the proboscis will run away." An Zhongzhi still tried his best to Lin Bei's instructions.

"Then let's do it for now, and we'll see it later in the evening."

By the end of the day, the elephant will not be able to eat much, and if the elephant is clever enough to cut some grass from a distance and feed it, then maybe by the evening the elephant will be full, and it will certainly not be as hungry as it was when it was first caught.

As soon as Lin Bei said this, An Zhongzhi could only nod, and suddenly thought of something again: "By the way, my lord, there are a lot of filth in the proboscis beast, and now it's hot, just one night, it stinks, mosquitoes and flies are flying, dare to ask adults how to deal with it?" ”

Elephants eat a lot, pull more, An Zhongzhi is also the first time to see, this morning to see, the elephant shed has several piles of filth, attracting a lot of mosquitoes and flies, the stench is extreme, let people cover their noses, this is only two proboscis beasts, if there are a few more, then the consequences An Zhongzhi really dare not imagine.

Lin Bei listened, but he was happy in his heart, he also had this purpose in catching elephants, and in the next step, Lin Bei was ready to build a biogas digester.

With the size and strength of elephants, in fact, there are not many places that can be used in the countryside, because most of the time ploughing cattle can also be replaced, comparing the heart to the heart, elephants eat more than cattle, but the work they can do is similar to that of cattle, anyone will like ploughing cattle and will not like elephants, then they have to make up for it from other aspects, this filth, that is, dung can show the strengths of elephants.

It's also a plus to a lot? Of course, if there is no biogas digester, then these dung are useless except for fertilization, but if there is a biogas digester, the manure can be converted into biogas, the role of biogas is too great, and the utilization efficiency of elephants has been greatly improved.

If each household can raise an elephant, then just the elephant daily dung to make the biogas can supply the needs of the family, in addition, biogas in addition to the fire heating, there are many other uses, fertilizer field fish farming and so on can use the residue and biogas slurry in the biogas digester, Lin Bei believes that raising an elephant does need a lot of food, but the use of these, and the shape of the industrial chain, counting up to raise an elephant not only will not lose money, but can also make money.
