Sang Jun felt his heart beating wildly. He looked at Zhang Yue, and the excitement in his eyes was already beyond words.

He knew what the message Zhang Yue conveyed to him meant?

It is the future, it is the guarantee!

If the son is still in power today, the Changsun can be established as the monarch of the next generation.

So……

For ministers who are secretly accused of beings like myself, the lower limit of the future future is at least 2,000 stones!

Maybe there is even a chance to be a marquis and ministers!

Just thinking about it makes me feel excited.

After barely forcing her to restrain her inner ecstasy, Sang Jun lowered his head and changed the topic, saying, "Mr. Shizhong, if it's not too early today, why don't you let the lower officials accompany Shizhong to inspect the various parts of the workshop garden?"

Zhang Yue nodded and said, "There will be a hard-working official..."

He turned around and looked at Chen Wannian beside him. Chen Wannian's face turned extremely flushed now.

Needless to say, he received the message.

Soon, almost the entire bureaucratic structure of Xinfeng will receive this message.

From a eldest grandson to a grandson, one word of the word, the status varies greatly.

After all, no matter how powerful the eldest grandson is, he is just the eldest grandson.

In the Han Dynasty, where mothers are valued by their sons and sons are valued by their mothers, Liu Jin's background was actually not good.

He was born by Shi Liangdi, not the legitimate birth of the Crown Princess Wang.

The mother's family has not yet a deep background. The mother's family's historian is just a landlord family in Hongguyuan, which is ordinary.

There are neither generals nor high-ranking officials in the family.

However, the prince still has three sons.

In fact, Liu Jin can have his current status because of his pampering.

Although the prince also likes this eldest son, however...

Who can tell the things in the palace?

Who can explain the future clearly?

Besides, Zhang Yue was not very relieved to Prince Liu Ju.

This prince is a gentleman, who is always kind and quiet, which is naturally an advantage, but when you think about it from another perspective, does it mean that the prince is actually weak in his ears and indecisive in character, and is easily influenced by others?

Therefore, in order to avoid the long nights and the long dreams, to reassure others, and to the future, Liu Jin must change from a eldest grandson to a grandson.

This matter is done.

Then in the future, even if Liu Ju ascended the throne, he would no longer be able to abolish the elders and establish the young people. This is a good thing for everyone.

But, this thing is not that easy to operate.

Zhang Yue still needs to sort out the relationship and think about how to operate it.

Before the incident, he had to have a good talk with Liu Jin and Liu Ju and his son so that Liu Ju could accept this matter.

After all, without Liu Ju's approval and support, there would be almost no room for operation in this matter.

Thinking of this, Zhang Yue had a headache.

It feels extremely tricky and troublesome.

But I had to do it, and even had to do it!

because……

The people below were pointing at him, Shangguan, leading everyone to build a well-off society, bring peace, and reaching the peak of life.

Among these people, only a few can use their ideals and dreams as their meals.

Most people must be counted on following Zhang Yue and Liu Jin, counterattacking wealth and beauty, taking the post of two thousand stones and reaching the peak of their lives.

If Zhang Yue kept dragging on his shoulders and refused to give them hope, and those who could not see hope for a long time would of course vote with their feet and make their choice.

If you don’t take the gift from heaven, you will be punished by heaven!

Thinking of this, Zhang Yue sighed helplessly. Surrounded by Chen Wannian and Sang Jun, he stepped out of the official residence of the Industrial and Commercial Bureau and came to the workshop of Shaofu.

This place has completely become one of the most technical handicraft workshops in Northeast Asia BC!

In the workshop, hundreds of houses of all sizes are endless, with many skilled craftsmen and more than two thousand officials and slaves shuttled and frolicked between them.

What is particularly noteworthy is the five large smelting furnaces built in the core area of ​​the workshop.

Zhang Yue observed that the shortest of these five iron smelting furnaces may be more than three meters high, and the highest may be more than five meters.

Rolling smoke rose from the furnace, and air outlets were opened on all sides of the furnace, and drums made by Shaofu were installed.

The so-called drum is actually the original form of a blower.

From the outside, it is a leather bag sewn from cowhide. It may have a support ring and baffle installed inside, which can be entered into the smelting furnace through human blasting, causing the furnace temperature to rise.

Cheng Yuan stood in front of these five vertical furnaces with great pride and introduced to Zhang Yue: "Shizhong, just these five vertical furnaces can produce two or three thousand kilograms of fine iron every day!"

"It's just a pity that Xinfeng County does not have iron ore, so it can only purchase pig iron from the iron officials in Lantian..."

Zhang Yue raised his head and looked at these vertical furnaces. Countless information and news flashed through his mind.

The data recorded by Lantai and the data from later generations were immediately combined, allowing him to form the basic parameters and three-dimensional structural diagrams of these vertical furnaces in his mind.

They should be a standard vertical furnace.

The so-called vertical furnace, as the name suggests, is an upright iron smelting furnace.

This is one of the symbols of the progress of iron smelting technology in the Han Dynasty during the old Qin and Warring States Periods, and iron has begun to be smelted and used by the Xia people in various fields.

But at that time, iron smelting technology was not up to standard.

The iron refined has poor quality, high sulfur content, and is easy to brittle and break. Compared with the mature bronze technology at that time, it is much more reliable and stable.

Therefore, the ending of the Warring States Period was that Qin, which made and used bronze weapons on a large scale, relied on the pinnacle of bronze technology to beat up the Eastern countries that used various advanced iron weapons and completed unification!

But in the Han Dynasty, everything changed.

Because, an iron smelting furnace appeared!

When this epoch-making blast furnace appeared, the old crucibles were immediately eliminated.

Especially in Han Shaofu and those former super iron merchant workshops, large iron smelting furnaces quickly eliminated the crucibles and the former bronze smelting industry.

At the latest during today's sub-rule, the vertical furnace technology began to appear.

And immediately replace other old iron smelting furnaces.

This kind of vertical furnace may be filled with various defects and unsafe designs and unreasonable aspects from the perspective of future generations.

But in contemporary times, it is one of the foundations of the Han family's strength.

because……

As Zhang Yue knows, later archaeologists have discovered and unearthed a large number of Han Dynasty vertical furnace sites.

After restoration, people came to the conclusion that this kind of vertical furnace can produce an average of 0.5-1 tons of iron per day, or smelting more than 200 kilograms of fine iron.

Especially the complete mid-year Han Dynasty vertical furnace unearthed in Guxing Town, which is amazing.

Combining Lantai records and data from later archaeological discoveries.

Zhang Yue now knows that these vertical furnaces are made of refractory bauxite and plate-building method.

The surrounding furnace walls are made of refractory bricks made of fired from a large number of refractory quartz stone.

It has an external feeding port and multiple human drums.

And the five vertical furnaces in front of you are probably three meters tall, and the highest one may even reach five meters!

The best iron smelting furnace of this era!

Conservatively estimated that as long as these five vertical furnaces are sufficient, they can refine three thousand kilograms of iron every day.

That is, more than 1.5 tons of fine iron.

The technical level is close to the iron smelting technology of Western continental Europe at the end of the 17th century.

only……

"It's still not enough..." Zhang Yue thought to himself.

At present, the iron smelting output of the Han family is about 2 million to 2.5 million kilograms per year.

It is approximately equivalent to the annual pig iron output of about 5,000-7,000 tons.

With such a small output, I am afraid that even the weekly output of a crude steel mill that was eliminated in later generations is not as good as that.

However, the annual demand for pig iron in the world far exceeds this number.

Therefore, the Han family's iron tools have always been in short supply, so that the country can make tens of millions of profits through official iron tools every year!
