Bracelet space through the past and present? Take it

Directly build an official school in each of the twelve cities in the northern border!

My cousin (Sister Lingling) has this kind of courage.

The problems encountered by Chen Jiaan and Zhou Zhuo were easily solved.

They already had experience in preparing for an official school.

It is May now. If nothing goes wrong, all the official schools in northern Xinjiang will be open in just one month!

The two men were full of fighting spirit and did not even bother to go home, but went straight to the official school.

It is easy to build schools and dormitories, but the most important thing is the teachers.

Nowadays, the teachers in official schools range from commoners, students to scholars and even juren.

Tongsheng is mainly responsible for the elementary school class, while the advanced education class is divided into different subjects. The teachers are mostly folk people with superb skills and scholars.

The Juren were responsible for teaching in the imperial examination classes. Of course, their number was pitifully small, only two.

But their northern border is no longer what it used to be.

I believe that as long as they extend an invitation, there will be more "people of insight" willing to come to the northern border and work with them to build a more prosperous and beautiful border!

Every member of the Zhou family, from the master to the servants, seemed to have found their own goal and was working hard for the future of this land.

Zhou Lingling is no exception.

Now my eldest cousin and Brother Zhuo, my second cousin, my parents and my uncle are busy with the planting and promotion of the new grain corn in the official school, and everything is progressing in an orderly manner.

On the contrary, except for Zhou Chi from the General's Mansion, no one else cared much about the developments in Shangjing.

It seems that it would be nice to just stay in the northern border and watch this land and the people on it get better day by day?

Of course it's impossible.

Zhou Lingling knew that Northern Xinjiang might be the starting point for their family, but it could never be the end point!

She will soon build the glass and plastic greenhouses mentioned earlier.

In this way, the northern border, having solved the problem of food and clothing, will have an industry that truly belongs to it.

In addition to solving the problem of a lack of vegetables during the long winter, we can also export glass, oil, or plastic greenhouses to the interior.

After all, the severe winter cold period in the northern border lasts for half a year, and the northern part of the Yuan Dynasty is no less severe.

The severe cold period in Shangjing lasts for four months.

Therefore, there is great potential for greenhouse and hothouse cultivation!

The official school has been built, and when the new generation grows up, the northern border will definitely not be the land of exile or barbarism as people say!

There is a set of oil separation equipment in Zhou Lingling's space. She tried it out over the past few days and basically mastered the separation principles and structure.

Several kinds of new grains and spiritual spring water. Zhou Lingling knew that she had exposed a lot, but she could still find excuses for these.

But it is really unacceptable to move out a large oil separator made of fine steel.

Zhou Lingling thought about it again and again, and finally used her not-so-professional skills to come up with a simple separator drawing.

Then I went to find the great military advisor.

Qi Zhu is very busy.

The Zhou family girl also needs to find a skilled carpenter and blacksmith.

But Qi Zhu really couldn't refuse the occasional "surprises" from Zhou Lingling.

Every action this girl takes is not groundless.

He sighed deeply and looked at his current right-hand man.

"Zhou Chi, I leave this matter to you. No matter what Miss Zhou asks for, I will do my best to satisfy her."

Zhou Chi readily agreed.

He hasn't seen his sister for a long time.

I only know that my sister asked Da Niu to send her a few large buckets of black water a few days ago, but I don’t know what they are used for.

As soon as Zhou Lingling saw her elder brother, her eyes lit up.

"Brother, you've come at the right time. I need your help with something..."

Qi Zhu didn't expect that his assistant would never come back once he was "borrowed".

Zhou Chi hurriedly asked the palace soldiers to pass on a message, saying that he was going out with his sister and would be away for three days.

Even with Mr. Zhuang, Mr. Du and others helping with chores, Qi Zhu was still tired as a dog.

The military supply mobilization of 50,000 troops also requires taking into account the news from the capital and the movements of the twelve border cities to prevent the northern barbarians and other tribes outside the border from taking advantage of the situation.

I’m old now, and it’s really... been a long time since I’ve worked so hard.

But it's not in vain.

The situation in Shangjing is very good now.

The old emperor was seriously ill and in a coma, and even if the empress dowager returned to the palace, it would be of no use.

The fight between several princes was brought to light, and the search for the general became less effective.

By now, the general should have found a way to enter the capital.

The Shuofang Army did work hard to stop the Northern Army, but what was the use?

If it were ten years ago, the Shuofang Army would still have been able to fight.

But since the emergence of the Northern Army, the once formidable Shuofang Army has retreated to Hanoi, and now cannot withstand the Northern Army's offensive for a single day...

Although Zhou Lingling also has an engineering background, she has nothing to do with materials engineering.

It's quite unusual that she has been dealing with ancient plants for thirty years and now she has to start studying how to extract ethylene from petroleum to make plastics.

After a few days of observation, she found that in the absence of large-scale equipment, there are probably three methods for preliminary separation of oil: distillation, liquid separation and adsorption.

She was going to use distillation.

As the temperature rises, the components with lower boiling points in the petroleum vaporize first. The simple condensation device used in the previous rice wine purification can be used to cool and liquefy the steam, and low-boiling point fractions, such as gasoline, can be collected.

As the temperature continues to rise, other components with higher boiling points will also be vaporized, condensed and separated in turn, such as kerosene, diesel...

Among them, the fraction collected at 150°C-300°C may contain more hydrocarbon substances suitable for preparing plastics.

After waiting for another three days, they gathered the best carpenters and blacksmiths in Anbei City and made the set of equipment that Zhou Lingling wanted.

She then took Uncle Tie, Daniu, and her elder brother Zhou Chi to her secret base.

This mountain is now heavily guarded by people from the General's Mansion. Except for specific people, no one else is allowed to come up.

Several caves were dug out next to the cave where gunpowder was originally made, which were Zhou Lingling's laboratories No. 1, 2, 3 and 4.

It goes without saying that Cave No. 1 was used for gunpowder manufacturing.

Cave No. 2 was filled with sulfur and saltpeter ores, which she had ordered to continue mining.

Laboratory No. 3 was still empty, but this time she chose Laboratory No. 4, which was the farthest away from the gunpowder.

A medium-sized crucible, a condensation device, oh, and a pile of coal.

Uncle Tie was in charge of lighting the fire, Daniu was in charge of carrying the things, and Zhou Chi and Zhou Lingling were in charge of collecting and separating the distillates at different temperature ranges...

After several days, they finally succeeded in obtaining gasoline, kerosene, diesel, and hydrocarbons of different fractions.

Gasoline and diesel are not available yet.

"But kerosene at this temperature can be preserved. It's more useful than the lamp oil we have now..."

"Brother, make another batch according to this temperature."

"it is good."

Zhou Chi nodded in agreement.

Zhou Lingling: "We have the precursors for making plastics, but now we just need a catalyst..."

She was thinking about what kind of catalyst would be best when she heard her eldest brother ask:

"Sister, what are these black things?"

Black thing?

Zhou Lingling looked back.

Another flash of inspiration came to my mind.

This is--

Asphalt!

If you want to be rich, build roads first!

Cement roads and asphalt roads, can't this also become another major industry in northern Xinjiang!

Oil is such a treasure!
