Marriage, a very old word.

For Qin Qing, he would never help Liu Kan easily. Even if she was well aware of the fact that Qin Man liked Liu Kan, as long as Liu Kan and Qin Man had no results for a day, she would not come forward to help Liu Kan for a day. It is undeniable that if Qin Qing comes forward, he can also bring benefits to the Qin family. But that's just the immediate benefit...... And in Qin Qing's heart, he cares more about the future of the Qin family.

No one could understand the Qin family's situation better than Qin Qing.

Qin Qing knows the truth of prosperity and decline. Today's Qin family, on the surface, is indeed infinitely beautiful. But this scenery, as she said, was built while she was alive. Of course, if Qin Man can marry Fusu, and the Great Qin Dynasty can continue, the Qin family will not have any problems for at least a hundred years. But the question is, can the Great Qin Dynasty continue?

The Qin family is a bit yin and yang.

The most outstanding person of the third generation is Qin Man. But Qin Man is a girl, and there are some fatal flaws in her character.

If Great Qin declines, the world will usher in an unimaginable chaotic situation.

In troubled times, an extremely strong, capable, means, and flexible figure is needed to preside over the overall situation. At this point, Qin Man is obviously not qualified. Therefore, Qin Qing needs to plan the future for the Qin family. Although she has not met Liu Kan, from the observation in the past few years, Liu Kan meets her requirements. No matter what aspect it is, Liu Kan is a suitable candidate.

Great Qin Xing. Liu Kan has been valued by Fusu, and he will definitely become an important minister after Meng Tian in the future.

He is only twenty years old now, and he has already obtained a tenth-class military merit knighthood, and he is the chief of the left. More importantly, Liu Kan was the military chief in the Sihong area, according to Qin Qing's investigation. Liu Kan won the admiration of those court magnates, and he had the clamor of the south to rely on, and the future was unlimited.

The Qin family joins forces with him, and they will definitely be able to keep the foundation of Bashu.

If Great Qin dies, it doesn't matter.

Judging from Liu Kan's current situation, he is not a master who is willing to live under others. He has strength and ability, and he has gathered a group of capable people around him, and his wings have been completed. If the turmoil comes, in terms of Liu Kan's capital. You will definitely be able to get ahead in troubled times.

Regardless of whether Great Qin is prosperous or dead......

The marriage between the Qin family and Liu Kan will definitely continue to survive. {First Reading} Take 10,000 steps back and say, even if Liu Kan fails, with Bashan Shushui and Liu Kan's means, he can keep the land of Bashu and become a prince. This is not unacceptable to Qin Qing.

But the problem is that Liu Kan already has a wife.

Let Qin Man be small? Qin Qing definitely disagreed. And the Qin family can't afford to lose this face. It only depends on what choice Liu Kan will make in the end.

Qin Qing had to make proper arrangements, and even more so, he needed to plan carefully.

As for Qin Man, he also guessed Qin Qing's thoughts. But she was far less than Qin Qing thought, so far.

There was a faint shyness in my heart, but more of a joy. After the messenger was sent. Qin Man began to wait anxiously.

At this time, Liu Kan was in the iron house, holding a drawing, silently watching.

Next to Liu Kan, there were three people sitting upright. In the center is Cheng Miao, who looks a little lazy and tired.

Above, there are ascetics who are over thirty years old.

He sat on the couch and stared with some curiosity at the wheels of the car in front of him. Some people may wonder, what is so beautiful about a wheel?

The ascetic doesn't look like a wheel. It's two wheels.

However, between the two wheels, there is an axle with the thickness of an arm, which makes the wheels form an organic whole.

The ascetic pushed, and saw the cart roll to the other side.

An old man in his fifties was also watching seriously......

He wasn't tall, about seven feet tall. But the body is strong. It's very strong. The hands are huge. It's like a fan.

The most characteristic thing is his eyebrows.

Under a pair of snow-white eyebrows, there are a pair of slender eyes.

Reach out. Steady the wheels. Looking up and down, I kept looking.

"Pan Lao, what do you think of this kind of wheel made by the captain?" The ascetic looked up, looked at the old man, and asked with a smile.

"Wonderful!"

The old man said softly, and then rubbed the axle, "This design of Du Weidi is indeed very wonderful. Not only can it avoid wheel slippage, but also enhance the stability of the light vehicle. However, there are still some details that need to be adjusted, and if assembled, the vehicle will be able to increase its combat power by at least 30%. However, those vehicles will probably need to be modified accordingly. ”

This old man is the Great End Alchemist who was introduced by the ascetic, Pan Ye Lao.

Panye Lao can be regarded as a famous family, and the twelve generations of his ancestors are all mainly based on casting weapons, and he is also a miscellaneous servant, and he is quite talented. It's just that his talent is not valued. Especially after the first emperor confiscated the gold and bronze in the world, private workshops were not allowed to cast weapons without authorization. Talented people like Pan Ye Lao have a sense of arrogance in their bones, and they would rather wash their hands than dry them than build tools like hoes and sickles. And those who are qualified to build weapons are of course unlikely to value a refiner craftsman.

Even if Panye is famous, these years have not been satisfactory.

Therefore, when the ascetic invited him, on the one hand, he and the ascetic were world friends, the ascetic's father, and Panno were always sworn brothers. On the other hand, he really didn't want to waste his craft. I also heard the ascetics say that Liu Kan is thirsty for talent, and has the style of Meng Weijun...... So with the intention of taking a look, I came to the building. But then, he was attracted by the vitality of Lou Cang.

And Liu Kan also attaches great importance to Panye Lao.

The reason is that the ascetic told Liu Kan in private. This Pan Ye Lao has mastered an extremely precious skill called Seventy-two Refining!

What is the Seventy-Two Refinements?

To put it simply, it is a smelting technology.

Before the Spring and Autumn Period, the smelting technology was relatively primitive, which was called the block refining method. Charcoal is used as fuel, which has low calories. In addition, the furnace body is also small. The blower equipment is also poor, so the furnace temperature is very low, and the melting temperature of iron cannot be reached. Therefore, most of the iron smelted is a sponge-like solid mass.

Using this block refining method to create a ground weapon, it is naturally impossible to use.

At the end of the Warring States period, after 500 years of exhibition, smelting technology has also improved by leaps and bounds. Although this period was dominated by bronze weapons, some alchemists did not stop further research. In the process of forging block iron and wrought iron, it is heated repeatedly. Iron absorbs the carbon in the charcoal. After increasing the carbon content and reducing inclusions, it becomes steel.

This kind of steel, with its tight structure and uniform carbon content, has been suitable for casting weapons and knives.

After twelve generations of painstaking research, the Pan family created the technique of seventy-two refining on the basis of the method of nine refining.

When making utensils, the number of folding and forging is consciously increased. A piece of steel often needs to be burned and burned many times. In the last years of the Warring States period, people were able to master the materials and equipment. The Pan family finally determined the limit of seventy-two.

The weapons created by this method have a finer structure, more uniform composition, and higher quality.

The only trouble is that this technique is too cumbersome. It's a huge cost. If you want to create a good weapon, it not only costs a lot of money, but also takes a long time. Ordinary people simply can't afford to spend this time, so it's not very popular. Besides, the bronze weapon at this time was at its peak, and the cost and time it took to create a weapon with the method of seventy-two refining could create a hundred excellent bronze weapons. Even the princes and nobles were reluctant to try the seventy-two refinements.

Panye's displeasure is partly because of the law. But most importantly, he hoped to promote the method of seventy-two refinements through his hands. In addition, he has high requirements for the quality of weapons, and a weapon that is already very good in the eyes of others may be nothing more than an inferior product in his eyes. As a result, fewer and fewer people are looking for him to build weapons. Until now, he has no reputation.

What exactly does the technique of the seventy-two refinements look like?

Liu Kan is also unclear.

But through the introduction of ascetics. Liu Kan was keenly aware of this so-called seventy-two refining technique. I'm afraid it will be the prototype of the 100-for-steel field that people are talking about hundreds of years later. Therefore, when Panye Lao returned from investigating the water quality, Liu Kan led his cronies and went out of Loucang City for ten miles to greet him. moved the old man of Panye, and burst into tears at that time and pledged his allegiance to Liu Kan.

The people of this era are very cunning, but they also have simplicity and loyalty that are far beyond the reach of later generations.

The concept of death for a confidant has been deeply engraved in the bones of many people. The more people are at the bottom of society, the more undesirable people are, the easier it is to be moved. Later, Pan Ye Lao heard that Liu Kan had a magic weapon in his hand, so he asked to take a look. Who knew that after Liu Kan took out the red flag, Pan Ye Lao couldn't help crying loudly. This red flag...... It turned out to be the hand of the old grandfather of Panye.

Back then, the grandfather of Panye Laodi exhausted his hard work to forge the red flag.

Thanks to the fact that the Kan family had that capital at that time, the daughter asked for a magic weapon and supported it in all aspects.

Panye's grandfather, the Great End Refiner Panjin at that time, actually used the method of refining a hundred times, which was still just a concept, and this created the Red Flag.

However, the year after the Red Flag was successfully built, Panjin died of illness.

The method of refining was lost. Pan Ye Lao was naturally very excited when he saw the divine weapon that his grandfather had forged with all his hard work.

It was also this magic weapon that made Panye follow Liu Kan with all his heart.

Sent people from the end of the day to take all the family to the building, Panye Lao seemed to have a second spring, all day long in spirit, especially excited.

After Liu Kan finished reading the chariot transformation drawings drawn by Pan Ye, he handed them back to Pan Ye.

"Pan Lao!"

Liu Kan thought for a while, and said in a deep voice: "I now have a total of fifty-four military vehicles in my warehouse, and I will hand them over to you to transform." Also, I want you to be in control of the Iron House, and I have some small things that you need to worry about. These things must not be easily spread.

How much does it cost and how much time does it take......

I don't even care! I have only one request, that the secrets of the Iron House must not be known without my permission.

I will order Lu Shizhi to stand guard outside the Iron Lu. No one is allowed to enter the Iron House without my order, except for you, father and son. Externally, you only say that you are making farm tools for me, and if someone asks, you immediately tell the walker, and the walker should know how to deal with it. ”

The implication of this is to beware of spies.

Although they didn't understand the true intention of Liu Kan's order, both the elder Panye and the ascetic felt the seriousness in Liu Kan's words.

Elder Panye immediately got up and replied, "Please rest assured, as long as I am here for a day, no one will know the secret of Tielu." ”

There are still two more today.
