After the Dragon Boat Festival, the weather became hotter day by day, and their place in Changle County became more and more lively day by day.
In fact, not only Changle County, Jinchang Dunhuang and other places are also very lively recently.
Although they do not have biogas lamps in those places, after buying lanterns and oil lampshades made of thorium stone from Changle County, the lighting conditions have improved.
It's actually much better than before.
As soon as the lighting conditions improved, the world seemed to become very lively all of a sudden, as if spring had finally begun after a long and long winter.
The lanterns and oil lampshades produced in Changle County were so useful that everyone who saw them were shocked and praised them.
The news naturally spread quickly.
Now, not only the vendors in the surrounding towns, but also those in Liangzhou City People come from thousands of miles to buy.
Even though a lampshade only sells for a few pennies, it can't support the large quantity.
The newly opened lampshade shop has to sell many trucks of goods every day.
After the Dragon Boat Festival, there were many merchants coming and going.
Luo Yong once heard a few idlers in the city joke that if the wooden track from Jinchang to Jiuquan was not paved, Guo Duhu would be able to make back his money.
It is said that Guo Xiaoke originally proposed to lay a wooden track from Jinchang to Jiuquan.
If it were just to pave it with wood and cement, the two governments in Jinchang and Jiuquan would be able to cope with it by providing part of the money and labor.
However, Guo Xiaoke said that since it needs to be repaired, it should be repaired better.
There are several rivers along the way, and it is inevitable to build bridges.
Ordinary wooden bridges are not durable, and stone bridges are too time-consuming.
Earlier, Luo Yong's disciples built a bridge in Gaochang A set of reinforced concrete bridges has been built on the wasteland between Dunhuang and Dunhuang.
It is quite good, if not all those bridges were built this time.
When officials in Jinchang and Jiuquan heard about it, they wondered how much fine iron would be needed to build these bridges, so they all complained to Guo Xiaoke that they really couldn't afford so much money and food.
Guo Xiaoke was surprisingly easy to talk to this time.
There was no money in Jinchang, Jiuquan and Jiuquan, so he used his own money and food to give them first.
Naturally, he paid more for this road, so the income from operating this wooden track , he must also take the big one.
Because of the wooden track incident, Guo Xiaoke has passed through Changle County several times recently, and his relationship with Luo Yong has eased a lot.
Tang Jian saw that the time was almost up, and told him the truth.
Regarding the mineral vein at Jiuquan, it was actually Luo Yong who revealed it to him, and he did not learn it from the mouth of that person himself.
"If that's the case, why did you want to lie to me that day?"
Guo Xiaoke sighed.
"You were angry at that time.
If I told the truth, I would have made you angry for nothing, but I'm afraid I might not be able to believe the mine."
Tang Jian explained to him.
Regarding this matter, Guo Xiaoke has actually been speculating these days that Luo Yong is an unusual person and seems to have some ability to understand astronomy and geography.
Perhaps as he said, his mind became enlightened after the illness.
Last year, Luo Yongcuo went to Yiwu to search for thorium stone, and finally made a biogas lamp.
How does he know that there is that kind of stone in Yiwu?
Since he knows that there is thorium stone in Yiwu, can he also know that there are mineral veins in Jiuquan?
Thinking about it this way, Guo Xiaoke decided that it was very possible that there were mineral veins in Jiuquan.
Even if his eldest son returns without success this time, the Guo family will not give up the search for this mineral vein easily.
That's why Guo Xiaoke was so enthusiastic about building a road this time, and asked for a reinforced concrete bridge to be built across the river, because in his vision, this road would be used to transport iron ore in the future, and the bridge The load-bearing capacity is naturally very important.
Every time he passed through Changle County these days, Luo Yong's hospitality was quite considerate.
He had gotten over his temper at this time, and now that he knew it was Luo Yong who told him where the mine was, he was naturally more grateful.
In this way, Magistrate Luo and Duhu Guo reconciled again.
Later, Guo Xiaoke asked Luo Yong to build a biogas digester in Gaochang.
Luo Yong told him that biogas was poisonous, flammable and explosive, so it was relatively dangerous.
At present, he himself has not fully understood the characteristics of this biogas, so he does not dare to spread it rashly.

It is better to wait for him to figure it out first, accumulate some experience, and then promote it to Gaochang and other places.
"How long will it take?"
Guo Xiaoke was a little impatient when he heard his refusal again, but what he said was not completely unreasonable.
Ordinary cellars would suffocate people to death, let alone their methane tank, which fermented feces and urine waste to extract miasma for lighting lamps.
In the eyes of people of this era, methane was similar to miasma.
Put it this way, the biogas thing is actually a bit scary, but it is economical.
These people in Changle County only need three cents to light a biogas lamp for a month.
If they switch to oil lamps, it will cost them no matter what. is not enough.
Moreover, at the price of three cents a month, the Changle County Government might still be able to make a profit, which shows how low the cost is.
"No more than one or two years," Luo Yong promised.
In a year or two, the biogas system here in Changle County should be relatively mature.
Some local people are also more experienced in the maintenance of biogas pools and the use of biogas.
When the time comes, it will be promoted to surrounding areas, and it will be a matter of course. things.
In the middle of June of the lunar calendar, the first biogas digester put into use was no longer producing much gas, and there was a lot of waste residue in the digester.
Even if it was filled with new materials, there was no improvement.
So Luo Yong said that a thorough dredging work should be done on the biogas tank.
During the use of the biogas digester, biogas liquid and biogas residue will continue to be produced.
Among them, biogas liquid is easier to handle.
The machine shop has already made a hand-pressed liquid pump, which is basically the same as the hand-pressed well of later generations.
When using it, just fix the liquid pump next to the discharge port, put the eucommia rubber tube connected to the pump body into the pool, and two or three young people take turns to get started.
In half an hour, the liquid in such a large pool can be pumped out.
Most of the biogas liquid is pumped out.
Every time they pumped out biogas liquid, the people nearby heard about it, and someone came to pick it up with barrels.
These days, no matter whether in the city or in the countryside, every household has to plant some vegetables in their yard.
Mix the biogas liquid with some water and pour it into the ground.
Those light green vegetable leaves will grow into dark green in a few days and are very fertile.
It's strong.
Some farmers on the outskirts of the city need a lot of fertilizer, and many people drive donkeys and carts into the city to pull it.
There was no chemical fertilizer at this time.
Because there was little land and many people, farmers planted large areas.
How to get enough fertilizer for such a large area was also a big problem.
Some children came out to pick up manure for this reason.
There is no charge for the biogas liquid in the city.
You can get it as long as you go there.
Sometimes when there are too many people going, the officials will open the outlets of several other biogas pools to see which pool has the highest water level. , then draw some more from that pool.
This is what Luo Yong specially warned.
Whenever people from nearby people come to collect the waste liquid and residue from the biogas tank cleaning, it is best not to ask them to return empty-handed.
If you often ask people to make a trip in vain, there will be fewer people coming back. , they pumped so much biogas liquid from the pond and no one wanted it, so where should they discharge it?
Although it is good to use the biogas liquid to fertilize the land, if no one wants it, too much water in the pool will affect the fermentation.
After it is discharged, it will flow everywhere, which will also greatly affect the environment.
In the past few days, the No. 1 biogas tank was desilted.
A liquid pump was also set up to extract the biogas liquid.
After the biogas liquid was roughly drained, the entire biogas tank was left open to dry for two or three days.
In the early morning of that day, several officials caught a chicken, tied its legs with twine and hung it in the methane tank.
After a while, they saw the chicken still chirping below, and they knew that the methane in the tank had dispersed.

It was almost done, so two or three people tied ropes to their bodies, and one person took an iron rake and went down to the bottom of the discharge port to remove the methane residue.
In addition, they set up a hand wheel above the discharge port.
The people below used iron rakes to rake the biogas residue into the dustpan, and then hung the dustpan on an iron hook hanging from above.
The people above shook their hands.
Turn the wheel and lift up the dustpan of biogas residue in just a few clicks.
There were already people waiting there, and at this time, some people came to help.
They took off the dustpans of biogas residue from the hooks, lifted them aside neatly, and poured them into the baskets they brought, or on wooden carts. superior.
Some elderly people also came to collect the biogas residue.
Some young and strong people on site helped fill the basket carts they brought.
While the people above are working, they must also pay attention to the movements of the people below.
If someone feels dizzy and has tightness in the chest, they must be replaced immediately.
They are all tied with ropes.
Even if they are weak and cannot walk, the people above will not be able to walk.
You can also drag it out for them.
After working for an hour or two, everyone stopped to take a rest and let the pool below ventilate again.
Then they arranged for people to go down and continue digging.
This time, they only stopped digging for less than half an hour because they were digging deeper and deeper.
The more we dig, the thicker the methane will become, and people will feel uncomfortable after being down there for a while.
For the sake of safety, we won’t dig any more today, and the pond needs to continue to diffuse air.
Such a large biogas tank was kept being dug and dug.
When it was finally completely emptied, I didn’t know how much biogas residue was dug out.
The residue in the pond was dug down to the bottom, and some scraps were left in the end, and some new materials were added.
It is summer now, the temperature is high, and the fermentation in the biogas pond is very fast.
It won't take long.
On the 1st, this No. 1 pond will be able to produce biogas again.
Speaking of which, the cleaning work of this biogas pool is really troublesome.
The pool is dirty, smelly, and dangerous.
Not only is it easy for people to be poisoned and suffocated, they don't dare to light the lights.
They just put a few bronze mirrors to reflect the sunlight.
Because of these inconveniences, many methane digesters were abandoned in later generations.
But the current era is different.
People at this time have no electricity, oil, or natural gas.
For them, biogas is already a very advanced, convenient and cheap energy source, so even if there are many inconveniences, they will never be abandoned easily.
This time, a lot of waste residue was cleaned up from the biogas tank, and many people in the city went to carry some of it home.
Even the old county magistrate Tan took his grandchildren to see the excitement twice and carried two loads of biogas residue back home. .
The biogas residue was left to dry in the backyard, and then they buried it next to the sweet potato nest.
This spring, almost every household in Changle County has planted sweet potatoes, but most households have not planted many.
The sweet potatoes from last year's keeper's house have sprouted, and each household is allocated a few twigs.
Take it home and plant it carefully.
The old county magistrate Tan's family has planted a lot of sweet potato seeds.
At the beginning of spring, it was only those in Changle County who had sweet potato seeds.
The farmers outside the city and the towns below would inevitably have some complaints.
At this time, Luo Yong took out a lot of sweet potato vines.
He said that he was reluctant to throw away these sweet potato vines last year, so he carefully collected them.
Although the leaves were completely dry, the vines still looked green.

He cut these sweet potato vines into small pieces. , distributed to every village under the jurisdiction of Changle County, so that the villagers can see various things and maybe they can still survive.
At that time, the old county magistrate Tan got a whole vine from Luo Yong.
He happily took it home, carefully cut it into sections and inserted them into the ground.
Unexpectedly, they all came alive.
Now the sweet potato field is growing green and lush.
The family can't help but enjoy it and tend to it carefully, looking forward to eating sweet potatoes this year. gd1806102:
