Bao Zheng?

When Li Jing saw this name, his eyes lit up, and Bao Qingtian's theme song couldn't help but sound in his mind.

There is a Bao Qingtian in Kaifeng, who is selfless and loyal and treacherous, and the heroes of the rivers and lakes come to help, and Wang Chao and Ma Han are by his side......

In film and television dramas and novels, Lord Bao appears as a blackface, with a crescent moon on his forehead, an iron face and selflessness, who can judge cases in the yang world during the day and judge the sins of the underworld at night!

Bao Zheng was born in the Northern Song Dynasty, he was honest and fair, resolute and resolute, not attached to the powerful, selfless, wise and decisive, and dared to redress grievances for the people, so he was named Bao Qingtian and Bao Gong.

Later generations worshipped him as a god, believing that he was the reincarnation of Kuixing, because of the folk legend of his black-faced image, also known as Bao Qingtian, in fact, Bao Zheng's face is not black at all, and there is no crescent mark on his forehead, which is caused by folklore.

Bao Zheng, what position should he be given?

Yes, the imperial examination will be held in a few months, so let Bao Zheng go to the scientific examination, let him go out, start with the county order, and then slowly promote up, anyway, Bao Zheng is not needed recently.

Now is the time to use cool officials to deal with Queen Wei's gang of rebellious ministers and thieves, Bao Zheng will only get in the way here, so it's better to let him out.

After arranging Bao Zheng, Li Jing took out the life skills encyclopedia and flipped through it.

The contents include daily necessities, buildings, and other contents that are closely related to people's lives.

It records how to mine coal, and the wide use of coal in life, construction, power generation, industry, etc., steam trains need coal, and coal is used to make cement and household fuel.

With coal, he was able to not only make cement, but also solve the problem of steam train fuel.

Li Jing decided to follow the method in the life skills encyclopedia and make a few bags of cement, provided that the raw materials were collected first!

The raw materials needed to make cement are limestone, clay, gypsum, slag, cinder, the specific proportion is recorded in the encyclopedia, and it is made according to the above method.

But before that, he needs to buy a lot of minerals.

Li Jing summoned Ximenyang, the governor of the palace, and instructed him to investigate the mineral situation near Chang'an, especially the coal mines, which were called coal in this era.

"Regent, the situation near Chang'an, the old slave knows a thing or two, there is a lot of charcoal on the north bank of the Wei River, I don't know if you plan to use it to make ink?"

Ximen Yang asked.

Graphite is the most primitive ink, before the invention of artificial ink, the general use of natural ink, semi-natural ink as writing materials, graphite is made of natural charcoal.

Nowadays, few people will use graphite, and the current ink is generally made of pine smoke, or ink made of oil smoke, and natural ink has long been withdrawn from the stage of history.

"It's not ink, is the charcoal there ownerless?"

Li Jing asked.

"In the early years, the sage gave the mountain with coal, part of which was given to the national abbot Wei Xuanzhen, and later the great sage queen abolished the sage, the Wei family was convicted, the mountain land was taken back and rewarded to Wu Sansi, after the Wu family was destroyed, the mountain land belonged to the imperial court!"

Li Jing showed a hint of surprise after hearing this, as long as it is an ownerless thing, it is easy to do, you can get him without spending a penny, and the coal mine can bring him rich benefits.

"Regent, the old slave has one more mouth, since you don't plan to make ink, what do you want charcoal for?"

Ximenyang said curiously, except for the fact that charcoal is useless except for being used to make graphite, it cannot be grown into crops, it can be said to be worthless, and ordinary people don't look down on it.

"I'm useful, you'll know when the time comes, by the way, in Chang'an City, as well as in the surrounding states and counties, post notices, saying that this king wants to buy coal and limestone, whoever has such a mountainous land, this king who is willing to sell will buy it, and the price will definitely not treat them badly."

Since you have decided to buy coal and limestone, you can't just buy a little, or don't do it, you have to do it to become bigger and stronger, and create brilliance!

Therefore, the more coal the better, and coal will become an indispensable resource in the future.

Since you plan to change the living standards of the people of the Tang Dynasty, of course, you can't just make a small fuss!

Therefore, he needs to take action, first determine the initial plan, and start to implement it.

"Ahh Regent, think twice! There is coal in the mountains but it is of little value, and if you buy it, you will lose money, and if you are going to do business, you might as well buy something else!"

When Ximenyang heard that Li Jing wanted to buy these useless things, he hurriedly persuaded Li Jing, lest Li Jing be hot-headed and the money in his hand would be wasted.

Coal is better, it can be used to smelt iron and copper, limestone has little effect, it is better to buy a few acres of fertile land, at least the fertile land can also grow grain.

He didn't want to see his master be bewitched by the ghost and do something stupid, if he didn't remind him, if he woke up one day and complained that he didn't remind him, he would be unjustly killed.

Ximen Yang was uneasy in his heart, and he didn't know if Li Jing had listened to it.

Li Jing did not have the same insight as Ximenyang, and the limitations of the times made Ximenyang's pattern not open, and it was normal not to see the benefits brought by coal.

"You don't have to worry about this, just do what I say, don't worry, as long as you do your best, if something really goes wrong, this king won't blame you, but if you dare to deceive your superiors and subordinates, I will definitely not spare you!"

Li Jing patted Ximenyang's shoulder and reminded him not to play tricks on him by the way.

"The old slave doesn't dare!"

Ximen Yang bowed and said.

Clay and gypsum are not difficult to find, clay is one of the main materials for making porcelain, and it is not difficult to find clay in layman's terms.

Gypsum is a kind of traditional Chinese medicine, which has the effect of clearing heat and expelling fire, removing annoyance and quenching thirst, and has the effect of aggravating sores and muscles, collecting dampness and stopping bleeding.

Commonly used for external fever, high fever and polydipsia, pulmonary heat wheezing cough, stomach fire, headache, toothache, etc., gypsum has a wide range of uses, and it is not difficult to obtain.

These Li Jing have all handed over to Ximenyang, the head of the palace!

In this way, the raw materials for making cement are all in place, and when all the materials are in place, the next step is to choose a good place to build a cement factory.

The kiln for forging cement is recorded in the encyclopedia, illustrated and illustrated, and as long as it is built according to the above, there is no problem at all.

Li Jing ordered someone to bring a map of the vicinity of Chang'an, and finally found a suitable site outside Chang'an City.

"This is it!"

"Regent, what's so strange about this?"

Ximen Yang came over and saw Li Jing drawing circles on the map, and asked curiously.

"You send someone to this place, look at the environment here, and draw a map back!"

Li Jing didn't explain much.

"Whoa!"

Ximen Yang took the order and left.
