The heavens start from saving Daming

The city of Chang'an was precarious, and there were an endless stream of major events and cases one after another, which could be described as thrilling.

However, these wind and rain did not affect Li Yunze who was thousands of miles away.

King Zhongshan of the Han Dynasty is in trouble at this time.

The reason is very simple, starting with Shi Fen and Zhang Ou, anyone who has a bit of status has given him a memorial.

The content of these memorials is almost the same, and they are all talking about one thing.

Please your Majesty give birth to an heir as soon as possible!
In the modern world. So everyone simply does not have children.

But in this era, one sentence can sum up the connotation of this aspect.

'There are three kinds of unfilial piety, and having no descendants is the greatest! '

Without descendants, the position of being an emperor is unstable. Zhu Qiyu said that he has a deep understanding of this.

There are no descendants among the people, neighbors will look down on you, and relatives are all sharpening their knives and waiting to be wiped out.

For King Zhongshan, if there is no successor, then the civil and military forces under his command will be unstable and want to find a way out.

After all, if there are no descendants, it means that power and wealth cannot be passed on smoothly. Of course, no one is willing to follow under such circumstances.

Because the wealth and power of the followers cannot be guaranteed.

In history, Liu Zhi was unable to give birth to a son for a long time, and he had experienced a serious crisis. When Wei Zifu gave birth to Liu Shi, he was immediately named the prince and rewarded with great rewards.

In theory, they are all the same.

Li Yunze's distress is that he is not only a king, but also a monk.

In the modern world, no one can succeed in cultivating the Tao. Apart from the exhaustion of spiritual energy and the lack of ancient hearts, one of the most important reasons is that there is not enough time.

Cultivating the Tao requires a lot of time, but human beings have a limited lifespan, so it is really impossible.

Li Yunze is different here, he has enough time to practice, so at this moment, he has reached the realm of alchemy and gas.

This stage literally means refining the gold of life into Qi for cultivation.

Solemnly declare that there is no problem at all in terms of ability, even because you have reached this stage, you can easily
Now everyone asked him to have a son, which made Li Yunze very distressed.

Or wait until the realm breaks through and reaches the stage of refining gas and transforming into gods.

Either give up the previous cultivation and return to the initial stage.

Li Yunze was reluctant to give up, but he couldn't break through in a short time, so he had to choose to procrastinate in distress.

Wait and talk, wait until it can't be dragged on, and then think of a way.

If Li Yunze was under ten pressures at this time, then Queen Zhuo Wenjun was under one hundred pressures.

For women in this era, especially those who married into the royal family, having no son is a terrible thing.

Because of this, Zhuo Wenjun's father, Zhuo Wangsun, even sent people from the middle of Shu to Lunu to bring his daughter a magic weapon.

Well, it is said that it is a miracle medicine prescribed by a genius doctor in Sichuan, as long as the king drinks it, he will die immediately.

On this day, Li Yunze returned from serving as a prisoner outside the city.

Back in the palace, in the hall, I was still writing and drawing on paper with a pen to carry out technological innovation.

Li Yunze knew very well that it doesn't matter how heavy the wind and rain in Chang'an City, as long as the umbrella in his hand is strong enough.

The only umbrellas that can protect against wind and rain are soldiers and horses.

His motto is 'the son of heaven, only the soldiers are strong and the horses are strong! '

After experiencing so many worlds, every time he fought for a position, he was defeated by soldiers and horses. He had never received alms from anyone, and this time was no exception.

If the emperor did not pass the throne to him, or if the imperial edict was tampered with or something, Li Yunze would definitely set off a Han version of the battle of Jing Nan!
Because of this, he is very concerned about armaments, and now he is busy changing equipment for Zhongshan's army.

"Your Majesty."

When Li Yunze designed the high-pressure bellows to blow air for the ironmaking blast furnace, Zhuo Wenjun, who was holding a jade bowl, walked over timidly and gave a soft call.

Get up, turn your head.

Seeing Zhuo Wenjun's slightly flushed pretty face, a smile appeared on Li Yunze's face, "The queen is here, what's the matter?"

"Your Majesty."

Zhuo Wenjun, whose pretty face was becoming more and more ruddy, did not dare to look directly into Li Yunze's eyes, lowered his crescent head and tremblingly handed over the jade bowl in his hand, "Please, please, King, drink the soup~~~"

The ancients said that 'medicine and morality do not separate families'.

People who are proficient in Taoism will naturally have good medical skills.

Of course, Li Yunze's medical skills and vision are excellent.

He reached out to take the jade bowl, first glanced at the almost viscous light red soup in the bowl, and then moved closer to sniff it.

"Um, ., ., ., ., .., .., ., ., car"

The words were full of affirmations, and he believed that his judgment on the medicinal materials would not be wrong.

However, his complexion gradually turned from astonishment to anger.

Putting down the jade bowl, Li Yunze said to Zhuo Wenjun, "You look down on me?"

Zhuo Wenjun was dumbfounded.

She said eagerly, "Your Majesty, forgive me, this concubine has no such intention~~~"

Li Yunze pointed at the jade bowl on the desk, and said dissatisfiedly, "."

Zhuo Wenjun breathed a sigh of relief, it turned out that the king was not really angry.

She covered her mouth and smiled lightly, and while her eyes were moving, the female Wenqing's temper flared up, "I don't remember the concubine, the king has not been here for a long time."

"Hehe~~~"

Faced with such provocations, Li Yunze has always disdained verbal quarrels.

He stepped forward very simply,...

Then he strode towards the apse in great strides.

In the apse, there is a soft and comfortable bed.

When launching a gentle offensive, it is really hard to resist.

Ever since the emperor Liu Qi filled Li Yunze with hundreds of beauties in one go, the manpower to serve in the palace has been insufficient.

In addition, Li Yunze didn't like eunuchs, so he could only recruit many Zhao women to work in the palace.

Compared with those beauties from all over the world, these girls from Zhao Di are really too bold, and they want to serve Li Yunze almost all the time.

They were recruited into the palace, but not for the monthly money.

Li Yunze, who was feeling emotional, suddenly hissed lightly.

hands forward
Li Yunze was not a person who was addicted to sex, he quickly adjusted his mentality, and continued to devote himself to the work of expanding the strength of Zhongshan Kingdom.

What is busy at this time is to innovate the method of smelting.

The basis for a Han to be the Five Hu is advanced weapons and armor, steel equipment that is enough to make the Hu people desperate.

Improving the quality and output of steel is the top priority.

Iron and steel, there is iron and there is steel.

Ironmaking is the premise of all metal products, and the basis of ironmaking is iron ore.

Most of Huaxia's iron ore grades are not high, which requires more and more advanced technologies.

To reduce iron ore in the form of oxides to pig iron, the main method is to put iron ore and charcoal layer by layer into a smelting furnace and slowly roast at low temperature.

The carbon monoxide produced by incomplete combustion of charcoal can reduce the iron oxide in iron ore to simple iron, and after cooling, it will form iron lumps, which are pig iron.

The carbon content of pig iron is very high, even reaching more than [-]%.

Such pig iron is basically unusable and must be purified to reduce the carbon content to less than [-] percent before steel can be obtained.

There was an iron-making blast furnace in Han Dynasty, and the method Li Yunze chose was to increase the oxygen supply in the blast furnace to make it react with the carbon in the molten iron, thereby reducing the carbon content in the molten iron.

He didn't have pure oxygen, but he made a high-pressure bellows.

This kind of bellows, which consumes a lot of manpower, can blow a large amount of air into the blast furnace, thus making the internal combustion more intense and the carbon neutralization reaction more intense.

And this is just the beginning.

When pig iron begins to boil, impurities such as silicon, manganese, and carbon begin to oxidize.

The iron-making craftsmen used tools and began to stir repeatedly, and the constant stirring made the oxidation more intense and faster.

When it comes out of the furnace, you can basically get low-carbon steel, and sometimes you can get medium-carbon steel and high-carbon steel.

There is no professional measuring tool, and the judgment depends entirely on the experience of the craftsman.

This is not over yet, after that, continuous, repeated heating, folding and forging will be carried out to make the structure of the steel dense, the composition uniform, and the impurities reduced, thereby improving the quality of the steel.

And this is Li Yunze's innovative technology of frying steel and steelmaking.

With steel, not only can weapons of better quality be forged, but also extremely powerful armor can be forged using hydraulic forging machines.

Li Yunze didn't choose the plate armor made of armor pieces, since the steel has been smelted, then there is no need for the plate armor, and he directly put on the one-piece plate armor.

The armor made of a whole piece of steel is not only stronger and more durable, but also more convenient to maintain.

Of course, in terms of the production capacity of this era, even with Li Yunze's innovative technology and strong support, the production capacity is still pitifully low.

At least from Li Yunze's point of view, it was pitifully low, not worth mentioning.

But in the eyes of Zhang Ougong, Sun Hong and others, this is a miracle!

The moment they saw the 'large-scale' steel tapping, they immediately dispatched sergeants to bring over the families of the supervisor craftsmen, and at the same time surrounded the entire prison, and even built a wall.

In what they said to Li Yunze, it is "the important weapon of the country, it must not be passed on to everyone's ears!" '

They are already ecstatic about the output and quality.

But here at Li Yunze, he is still dissatisfied and plans to continue to innovate technology.

But soon, an imperial decree from Chang'an City made Li Yunze's eyes turn away from technological innovation, and turned to the grasslands in the north.

The imperial decree said that a group of Xiongnu tribes wanted to surrender to the Han, and ordered the king of the mountain to lead his troops out of the fortress to welcome them back!
