Day 2.

Lin Bei and his entourage came to the school.

The people have already gone to work and are busy, Lin Bei wanted to take a look at Xu Shu and the others, but learned that the three of them were still sleeping.

"Your Excellency." An Zhongzhi smiled at Lin Bei and said: "Yesterday, the three of Shan Fu were poured some wine by the people, and they were already drunk when they helped them back, and they haven't woken up yet, my lord, I'm going to call the three of them now?" ”

Xu Shu and the three of them are already a special group in the people, and now they don't have to do things, so An Zhongzhi didn't call them early in the morning.

"Forget it, wait until they wake up, let's go see the digester, are all the things I want ready?"

"It's ready, my lord really sympathizes with them." An Zhong didn't forget to praise it.

Lin Bei has been able to ignore this kind of praise, but he feels that An Zhongzhi is becoming more and more like Sun Ning.

There was no one by the biogas tank, after Lin Bei caught the night watchman sleeping last time, An Zhongzhi was very attentive to this matter, he felt that the night watchman was not very reliable, so he simply gave a strict order to the people, strictly prohibiting these people from approaching, although the people did not understand their meaning, but the biogas digester is now just like a grave-like place, there is nothing strange at all, and the people will not come over because of curiosity, saving a lot of worry.

Lin Bei walked around the biogas digester, felt the temperature in the lower pool, and after thickening, with Lin Bei's sensing ability, he didn't feel warm anymore, and sniffed the plug of the thin iron pipe, which was tightly sealed and not breathable at all.

The digester has been around for four days, and according to the current heat, there must have been a lot of biogas produced in it.

If the biogas digester is successful, it will be the first cross-era project left by Lin Bei in this era, which is enough to bring unpredictable and far-reaching impact to the people of this era, so Lin Bei was stunned for a long time and wrote cautiously: "Bring the torch." ”

Cui Lan picked up the torch and stood beside Lin Bei, waiting for Lin Bei's orders.

"Open the stopper."

An Zhong took a step forward and unscrewed the iron stopper.

As soon as the iron plug was opened, Lin Bei heard the sound of snorting dew, and at the same time, he also smelled the smell of biogas, and hurriedly said, "Ignite." ”

Cui Lan put the torch on top of the thin iron pipe, and then put it back, and then, only to see the blue fire at the mouth of the thin iron pipe, and the fire was not small, because there was a lot of biogas in the biogas tank, and it was full of momentum when it rushed out of the thin iron pipe.

"Wow, can you really light it?"

"Can it burn all the time?"

Although Lin Bei has already said the effect of biogas, it is better to hear than to see, even an ordinary iron pipe can catch fire, and everyone still thinks it is incredible.

Bian Ji leaned in front of the thin iron pipe, looked at it with a surprised face, and finally sighed in admiration, looking at Lin Bei: "My lord, this is a divine fire." ”

Lin Bei was speechless, he said that it was biogas, science is just that, do you still have a divine fire? Lin Bei didn't bother to pay attention to him, Bian Ji's brain would sometimes open up.

For a minute, two minutes, Lin Bei kept watching the fire.

The fire was quite stable, and seeing that it seemed to be able to burn all the time, Lin Bei was completely relieved at this time, and turned around and wrote: "What about the iron plate furnace?" ”

After the biogas digester was built, Lin Bei had already instructed An Zhongzhi to ask someone to make an iron plate stove, which used a tandoor oven under this iron plate stove, hollow, and wrapped in a thin iron sheet on the top, a bit like the kind of equipment used to sell roasted sweet potatoes in modern times, but it must be much simpler.

An Zhong shouted, and one person carried the stove over, and according to the instructions, placed the iron plate furnace on top of the thin iron pipe, and placed a few stones underneath, and after placing it, it happened that the top of the fire could bake the thin iron sheet on it.

After a while, the thin iron sheet had become hot, An Zhong dropped a few drops of water on it, and with a snort, the water steamed, "My lord, the temperature seems to be okay." ”

"Okay, Mrs. Feng, come on."

Feng Niangzi stood up, holding a thing like an enlarged version of Zhu Qingfei in her hand, using this thing to pick up the grease in a bowl on the side, knocking it on the iron plate, the grease melted quickly, Feng Niang quickly scooped up the batter in the wooden barrel on the side, poured it on the iron plate, and Zhu Qingfei scraped it twice, forming the appearance of a cake.

Seeing this, modern people are probably quite familiar with it, yes, this is making pancakes.

When repairing the biogas digester, Lin Bei has been thinking about how to maximize the effect of biogas, biogas is only used for cooking and boiling water Lin Bei feels that it is really a bit of a waste, if biogas can be integrated into all aspects of people's lives, then the biogas digester will be quickly promoted, and finally, Lin Bei thought about this pancake.

The process of pancakes is almost none, it is quite simple, anyone can almost do it after reading it once, and the most important thing is the cost of pancakes, if the cost is too high, pancakes cannot be popularized, so Lin Bei let them use barley flour and soybean dregs, of which bean dregs also account for most of them, bean dregs are the poorest people in this era, and those who are a little more generous at home will not eat them.

The thin pancakes cooked quite quickly, almost instantaneously, everyone smelled a fragrance, grease, soybean and wheat, Feng Niangzi quickly took out an egg, cracked it, poured it, and then turned the pancake over, this side was already burnt yellow, and it looked very appetizing.

In the eyes of the crowd, the first pancake came out of the pan and rolled into a ball and placed in a bowl.

Lin Beidao: "What do you think?" ”

"Magical"

"Incense"

"It should look delicious."

Lin Bei was speechless and had to ask again: "I'm asking if this method can be popularized?" ”

"My lord, who is this cake to eat?" Bian Ji asked an important question.

"Do some work for the county." Lin Bei's positioning of pancakes is these people, for example, people like people who come to build roads are also counted in this category.

If Lin Bei doesn't care about food here, these people are actually quite pitiful, they can hardly eat hot food at every meal, they bring their own bread and other things, many people can't even eat pickles, these people are very poor.

Bian Ji and the others thought about it, and Cui Lan replied first: "My lord, if this kind of bread is sold to those people, Cui Lan thinks that it is very promising, the value of this thing is not high, and it is only about ten dollars in total, and those people can really afford it." ”

At present, the most valuable thing about this pancake is actually eggs, fat and barley, but there is very little fat, and it is lard, a pound of barley ground wheat flour is enough to make a hundred pancakes, because the bean dregs account for the majority, and then there are eggs, which still account for the majority of eggs, but this egg can be replaced by wild eggs, and pheasants lay more eggs than domestic chickens, so the cost is really very little, if you have to say anything else, then the stove is one, but the stove is worth a little money on the top of the iron sheet, and everything else is mud, Everywhere.

Of course, this biogas is still unique, but biogas is not irreplaceable, it can be replaced with charcoal, which is also the reason why Lin Bei asked Feng Niangzi to leave the charcoal, Lin Bei is considering that there are many mountains and trees in Nanyue, so there may not be a shortage of charcoal, but there are fewer mountain trees in the Central Plains, and people there can use biogas.
