Thinking too much, so his thoughts became very complicated, and not only that, Zhang Yi even went back to the biogas digester. Pen, fun, and www.biquge.info

Although it is very simple to build a biogas digester, with only a little cement, gravel and river sand, he believes that he can make a perfect biogas digester. However, it is not always usable, and if there are no pipes and valves, then even if it is made into a biogas digester, it will have no effect.

In ancient times, there was such a little bit of a bad thing, if you want to get something out, you not only need enough manpower and material resources, but also need to meet all relevant conditions, so thinking of this, Zhang Yi felt that there were 10,000 *** running wildly on his head.

One word, difficult!

Therefore, thinking too much now is actually a flower in the mirror and a moon in the water!

Of course, with Zhang Yi's temperament, it is impossible to get any pipes or valves in order to save a little firewood money, if you want to get it, you have to involve many prerequisites, it is estimated that if you really want to make a usable biogas digester, he will fall into it in his life.

Since the digester could not be used, Zhang Yi put the idea on the coal, and of course now it has a name, called Carbon.

Zhang Yi knows very well that there are coal mines in Shaanxi, for example, in Jingyang, and there are quite a few. The most important thing is that in this era, coal has not been developed and used at all, and even many places have appeared in the form of open-pit mines.

You know, although some people now know that this thing can be used to heat the fire, but because soot contains a lot of carbon monoxide, and inhaling too much of this thing can directly cause death.

Because people die, no one usually uses coal unless it is absolutely necessary!

Zhang Yi thought about it, and felt that coal was definitely a good thing, not only to help him make a fire, but also to make money! If you can find a rich mine and make it into honeycomb coal.... It's hard not to get rich!

"Old Zhong, do you know if there is a charcoal near our Zhuangzi?" Thinking of this, Zhang Yi asked Lao Zhong.

"Coal?" Lao Zhong was stunned for a moment, he was really asked by Zhang Yi, after thinking about it, he always felt that he had seen it there, but he couldn't remember it, so he was puzzled at the moment: "Young master, what do you want charcoal for?" That thing is poisonous! ”

As he spoke, he scratched his head and thought, "I saw it in our Zhuangzi a while ago, but I can't remember where I saw this thing!" Otherwise, I'll help you find the third uncle, his old man must know! ”

"Yes!" Zhang Yi nodded, the third uncle is a living fossil of Zhangjiazhuang, if he doesn't know, then I'm afraid it's useless to ask others, but when he thought of the third uncle's walking speed, Zhang Yi still decided: "Forget it, let's go to the third uncle's house and ask, it's so late, walking at night, if something happens to his old man, he will be big!" ”

With that, the master and servant walked towards the third uncle's residence.

As soon as I left the room, I saw the old lady coming over with a group of maidservants.

"Grandma!" Zhang Yi hurriedly stepped forward to salute.

Lao Zhong also bowed slightly, and arched his hand: "Lao Zhong has seen the old lady!" ”

For the old lady, Zhang Yi has suffered a lot of sins in her old man's house in the past two days, if he wasn't annoyed by his chatter, he wouldn't have gone to live in Chang'an, in the final analysis, he was still thinking about hugging his grandson, crying if he didn't agree with him, and she didn't stop crying until she lowered her head and admitted her mistakes.

Not only that, but even Yunren suffered a lot of anger, and Xiao Nizi still followed her with red eyes and didn't dare to speak.

"Where is this?" The old lady glanced at the old bell next to her, a little unkind to him, and then said to Zhang Yi: "Are you still going to leave the house so late?" ”

In the old lady's opinion, as a housekeeper, the most important duty of Lao Zhong is not to be busy with the affairs of the Zhuangzi at all, why do you do so much? Isn't it cheaper than those bankers in the Zhuangzi?

You can make some copper money, but that's not the point! The key thing is that this old boy is not doing his job!

What is most important as a housekeeper? What should I care about the most?

Then it has to be the uncle's heir!

Won the trust of the uncle, but I didn't know that sometimes I didn't blow the wind on the uncle and get married early, which is the biggest dereliction of duty!

And it's so late, the old boy actually went out with his uncle, God knows that something went wrong in Zhuangzi again......

Lao Zhong is naturally not good at talking about himself, as long as he stands aside respectfully and does not speak.

Zhang Yi smiled and pulled the old lady's hand, and said with a smile: "Grandma, just now my grandson found a big deal again, if this thing is done, our Zhang family will really grow in the future!"

So at this time, I am pulling the old bell to the third uncle's house to discuss, if there is no third uncle, I am afraid this matter will not work! ”

"Hey!" The old lady not only sighed, but also muttered, "What a bitterness for my good grandson!" It's only so old that you have to handle the work of the entire Zhuangzi! As he spoke, he said to Yunren who was following behind: "Yunren, you should follow Brother Yi'er, it's cold at night, bring another piece of clothing!" ”

Yunren hurriedly walked up to the old lady and answered, "Yes, old lady!" ”

.......

It's night, but it's not dark!

The starry sky is like a vast and boundless jade plate, and a bright gem on the west side of the jade plate is exuding endless brilliance.

The third uncle's residence is not far away, and Zhang Yi has already gone there for the second time, so he soon arrived at the door of the third uncle's house.

"Third uncle!" As soon as he arrived at the door, Zhang Yi knocked on the lock on the door.

"Knock knock!"

The rough wooden door immediately made a crisp sound.

Soon, the light of the oil lamp inside became a little brighter, and apparently the owner of the inside picked the wick up a section, so it was even brighter.

Then a footstep came through, and as soon as he opened the door, Zhang Yi saw the little boy he saw last time sitting in the room practicing calligraphy.

"Uncle!" The little boy was stunned for a moment, he didn't expect that the person who came would be Zhang Yi, but after just a meal, he immediately came back to his senses, and saluted respectfully: "Uncle, you... Sit in the house! ”

Zhang Yi was very satisfied with the little boy's performance, and said that reading is to know right from wrong and know etiquette, although I don't know if this little boy can know right from wrong, but this etiquette is still quite good!

Entering the house, the third uncle was lying on the chaise longue with his eyes closed, and beside him, a middle-aged woman was putting a pot of warm wine on the low table in front of him, and on the left was a small dish of boiled peas, and it seemed that the old man was about to drink.

"Third uncle, is your old man drinking?" Zhang Yi walked up to the third uncle with a smile and said, "I won't delay you here, right?" ”
