The wind and rain in Chang'an City are turbulent, and there is an endless stream of major events one after another, which can be called thrilling.

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

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

The reason is very simple, starting with Shi Fen and Zhang Ou, but anyone who has a little identity has given him a lesson.

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

Please give birth to an heir as soon as possible!

in the modern world. So everyone simply stopped having children.

But in this era, this connotation can be summed up in one sentence.

'There are three unfilial pieties, and no queen is great! ’

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

There are no descendants in the people, the neighbors will look down on you, and the relatives are sharpening their knives and waiting to eat the end of the household.

For the King of 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, the absence of descendants is equivalent to the inability to ensure that power and wealth can be passed on smoothly, and of course no one wants to follow in such a situation.

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

In history, Liu Yu failed to give birth to a son for a long time, and he experienced a serious crisis, and when Wei Zifu gave birth to Liu Ju, he was immediately named the prince and rewarded him.

Logically speaking, it's all the same.

Li Yunze's distress lies in the fact that he is not only a great king, but also a cultivator.

In the modern world, no one can succeed in cultivating, in addition to the exhaustion of spiritual energy and the immortality of the human heart, a very important reason 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 to do it.

Li Yunze was different here, he had enough time to cultivate, so at this moment, he had reached the realm of alchemy and qi.

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

For the record, there is no problem at all in terms of ability, and even because it has reached this stage, it can be easy and comfortable

Now everyone asks him to give birth to a son, which makes Li Yunze very distressed.

Either wait until the realm breaks through and reaches the stage of refining qi and transforming gods.

Either you give up your previous cultivation and go back to the initial stage.

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

Wait and wait, and then figure out a way when you can't drag it out.

If the pressure on Li Yunze at this time is ten, then the pressure on Queen Zhuo Wenjun is one hundred.

For the women of this era, especially for these women who married into the royal family, it was a terrible thing to have no sons.

Because of this incident, Zhuo Wenjun's father, Zhuo Wangsun, even sent people from Shuzhong to Lunu all the way to send a magic weapon to his daughter.

Well, it is said to be a miracle medicine prescribed by the divine doctor in Shuzhong, as long as the king drinks it, he will immediately be.

On this day, Li Yunze returned from being imprisoned outside the city.

When I returned to the palace, I was still writing and drawing on paper with a pen in the palace, and I was carrying out technological innovation.

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

And the umbrella that can shelter from the wind and rain is only soldiers and horses.

His motto is 'Son of Heaven, only soldiers are strong!' ’

has experienced many worlds, every time I grabbed a position, I relied on soldiers and horses, and I never accepted anyone's handouts, and this time is naturally no exception.

If the Son of Heaven did not pass on the throne to him, or left an edict but was tampered with or something, Li Yunze would inevitably set off a Han version of the Battle of Jingjing!

Because of this, he is very concerned about armaments, and now he is busy changing equipment for the army of Zhongshan Kingdom.

"The King."

When Li Yunze designed the high-pressure bellows and blew the artwork for the iron-making blast furnace, Zhuo Wenjun, who was holding the jade bowl, timidly walked over and called softly.

Get up and tilt your head.

Looking at Zhuo Wenjun's slightly flushed pretty face, a smile appeared on Li Yunze's face, "The king is coming back, what's the matter?" ”

"The King."

Zhuo Wenjun, whose pretty face became more and more ruddy, didn't dare to look directly at Li Yunze's eyes, lowered his head and trembled, and handed over the jade bowl in his hand, "Please, please drink soup from the king~~~"

The ancients said that 'medicine is not separated'.

For those who have sperm channel surgery, their medical skills will naturally not be bad.

Li Yunze's medical skills and vision are of course very outstanding.

He reached out and took the jade bowl, first at the almost viscous pale red soup in the bowl, and then leaned closer to sniff it.

"Well,.,.,.,.,..,..,.,., car"

The words were full of affirmation, and he believed that his judgment of the medicinal herbs would not be wrong.

It's just that his face gradually changed from stunned to angry.

Putting down the jade bowl, Li Yunze gave Zhuo Wenjun a sentence: "You look down on me? ”

Zhuo Wenjun was directly dumbfounded.

She eagerly said, "The king forgives the sin, the concubine has no such intention~~~"

Li Yunze stretched out his hand and pointed to 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 chuckled, and her eyes flickered, and the female Wenqing's temper attacked, "I don't remember the concubine, the king hasn't been here for a long time." ”

"Hehe~~~"

In the face of such provocations, Li Yunze has always disdained verbal quarrels.

He stepped forward very simply,.。

Then he strode towards the apse.

In the apse, there are soft and comfortable beds.

When a gentle offensive is launched, it is really difficult to resist.

Since the last time Liu Qi, the son of heaven, stuffed Li Yunze with hundreds of beauties in one go, there were not enough people serving in the palace.

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 much bold, and they want to serve Li Yunze almost all the time.

They were not recruited into the palace for the little money they had.

Li Yunze, who was sighing, suddenly hissed lightly.

Hands forward

Li Yunze was not an indulgent drinker, he quickly adjusted his mentality and continued to devote himself to the work of expanding the strength of Zhongshan Kingdom.

At this time, what is busy is the method of innovating smelting.

The foundation of the Five Hu is advanced weapons and armor, which is enough to make the Hu people desperate.

Improving the quality and yield of steel is a top priority.

Steel, steel, there is iron, there is steel.

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

Most of the iron ore in China is not of high taste, which requires more and more advanced technology.

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

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

Pig iron has a high carbon content, even reaching more than four percent.

This kind of pig iron is basically unusable, and it must be purified to reduce the carbon content to less than 2.1 percent in order to obtain steel.

In the Han Dynasty, there were already iron-making blast furnaces, and the method chosen by Li Yunze was to reduce the carbon content of the molten iron by increasing the oxygen supply in the blast furnace and causing it to react with the carbon 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, so that the internal combustion is more intense and the carbon neutrality reaction is stronger.

And that's just the beginning.

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

The ironmakers used their tools and began to stir repeatedly, constantly stirring to make the oxidation more intense and faster.

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

There are no professional measuring tools, and it is all up to the experience of the craftsman to make judgments.

This is not the end, after this, it is necessary to carry out continuous, repeated heating, folding and forging to make the structure of the steel dense, the composition is uniform, and the impurities are reduced, so as to improve the quality of the steel.

And this is Li Yunze's innovative technology of frying steel, as well as 100 steel.

With steel, not only can you create better quality weapons, but you can also use hydraulic forging machines to create extremely powerful armor.

Li Yunze didn't choose a armor composed of armor pieces, the steel has been refined, so there is no need for armor, and he directly puts on a one-piece half-body plate armor.

Armor made of a single piece of steel is not only more durable, but also easier to maintain.

Of course, in terms of the production capacity of this era, even if Li Yunze innovates technology and greatly supports it, its productivity is still pitiful.

At least in Li Yunze's opinion, it is low and pitiful, the kind that is not worth mentioning.

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

At the moment of seeing the 'large-scale' steelmaking, they immediately sent sergeants to bring in the families of the craftsmen who were working in prisons, and at the same time surrounded the entire prison, and even built a wall.

In their words to Li Yunze, it is 'the important weapon of the country, not to be passed on to the ears of everyone!' ’

They are already ecstatic about the yield and quality.

But here Li Yunze, he is still not satisfied, and plans to continue to innovate technology.

However, soon, a holy decree from Chang'an City made Li Yunze's eyes move away from technological innovation and turn to the grasslands in the north.

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