When molten iron flowed out of the blast furnace, everyone looked at each other with longing for them.

It was the iron master Zeng who reacted first: "Quickly pour the blacksmith into the mold!" ”。

A group of people poured molten iron into the sword casting mold prepared in advance, "Add manganese powder." Then a small servant poured a small pinch of weighed manganese powder into the mold, and in a blink of an eye, it was integrated with the molten iron.

"Wrought iron!" The two men opened the mold, put the slightly cooled red iron sword on the building table, and swung the heavy hammer, striking it one by one.

Zeng Tieshi stared at the embryonic sword that was being tempered with anticipation, it was the first time he had cast a sword like this, and his expectations even exceeded the hijab of his wife when he married his relatives.

Xu Yang doesn't have much, the proportion of iron and carbon is all according to his own explanation, the current forging is to remove the excess carbon of pig iron, the carbon content of pig iron is 2%-4.3%, and the carbon content of steel is generally not about 1.7%, just that few percent of the carbon content determines whether it is soft pig iron, or hard steel.

What's more, a small amount of manganese powder is added to make an alloy, and the hardness must be much greater.

After knocking for more than an hour, the big man who struck iron changed three waves, and even Xu Yang personally went up to get addicted, forging, cooling, and then forging, and refining it for thousands of times, the ancients did it right, but their iron-making method was too backward, and the carbon content in the original iron had exceeded the standard too much.

It usually takes a few days for the Tang people to make swords, but it is really rare for a method like Xu Yang to be made in just a few hours.

The iron sword was put into the water tank for the last time, and the last trace of heat was eliminated, and the first alloy sword of the Tang Dynasty was cast.

The last corner was polished with diamonds, and the sword opened, and a clear sound came from the sword body.

"Sword Jackie Chan, it's really a good sword, a good sword!" Zeng Tieshi stared at the sword with blazing eyes.

"Come on, try the sword!" The eldest grandson Wuji is also eager to try.

"Uncle, my little nephew wants to try this sword first, but it is as sharp as my herring sword, ask my uncle to agree!" The eldest grandson in a green robe stepped forward.

"That's right." The eldest grandson Wuji waved his hand.

"No!" I saw the eldest grandson walking to the cast iron platform in three steps, pulling out a sharp iron sword from the sword box on his waist, and ordering someone to stand with the newly cast sword in his hand, the eldest grandson Yang said loudly: "The sword under the sect is given by Li Chunfeng Dao of the Holy Palace, sharpen the iron like mud, destroy the evil demons, the sword is three feet long, weighs two and a half catties, the name is 'herring', come to try the sword today!" ”

With that, he waved the sword in his hand and slashed down.

"Bell!!" A screeching clash of blades came to mind.

Where the two swords intersected, there was a faint flash of thunder and lightning.

When the blow fell, everyone looked at the freshly cast sword, but the sword was still as smooth as new, and there was no trace of collision.

"Ahh As a result, the eldest grandson screamed, only to see that there was a small gap in the herring fish sword given by Li Chunfeng.

The eldest grandson was distressed, and the wound on the originally indestructible sword would be cut out instead.

"Again, this time I will use a forged sword to split the herring sword." As soon as Changsun Wuji saw the herring sword with a gap, he knew that the sword had no value, and its final value was to make it one more time to see if it was a coincidence.

The eldest grandson Yang is also a person with a firm mind, just a sword, ordered the craftsman to take it, picked up the newly cast sword himself, stood in a good position, and once again tried his best to slash down, this time maybe it was distress in his heart, he really did his best, and when the long sword was chopped, there was a faint sound of breaking the air.

"Bell !!" This time, the sound stopped abruptly, and it turned out that the herring sword was cut into two pieces!

Looking at the newly minted sword with only a few white marks, the scene fell silent for a while

Strange things have happened frequently in Chang'an City recently, as if after the disciples of the Ghost Valley came to Chang'an, it seems that the whole city is faintly boiling, the business clubs on the streets of Xishi are full day by day, and the parking lot in front of the building is full of carriages of the palace nobles all day long, and the people are curious about this renovated restaurant, but they are not qualified to enter lightly, and the membership card that has risen to five hundred yuan is not something that ordinary people can buy.

Mahjong has spread, and now not only Xungui is playing, but even some well-off families have begun to come into contact, and they are not tired of it.

Now, a monster emitting black smoke suddenly appeared on Suzaku Street, stirring up this primitive Chang'an City.

Xu Yang was very happy at this time, although it was bumpy to sit on the steam car, it was very windy, all the Tang Dynasty people along the way would stop and look at the car they drove, and a few timid people would be scared and tremble, originally saw the bicycle on Chang'an Street was very attractive, and now there is a big guy who can spit black smoke, which is no less than the European horse-drawn copper ball The atmosphere compacted yàn attracted the people of the entire city-state.

The drawings of blast furnace ironmaking have been handed over to the eldest grandson Wuji, which completely solved the eldest grandson's long-standing heart disease, under the eldest grandson Dayue, and Xu Yang signed a share of the future iron making, Xu Yang does not have to do anything, and all the iron tools of the eldest grandson family are divided into one percent, which makes Xu Yang very satisfied, the contract is ten years, provided that Xu Yang has any iron inventions in the future to continue to provide to the eldest grandson's family, and the eldest grandson Wuji gave Xu Yang a false position, an honorary iron master.

The two descendants of the eldest grandson family have already worshiped Xu Yang's ghost valley magic skills, and they insist on learning from Xu Yang, Xu Yang does not refuse, the big tree of the eldest grandson's family does not climb in vain, so the eldest grandson Chong and the eldest grandson Yang rightfully entered the Zhongnan Mountain fiefdom of Xuyang and participated in the construction of Xuyang's fiefdom.

Now the foundation of the fiefdom is basically all dug up, and the drawings for building the building Xu Yang have also been given to those craftsmen, many of those craftsmen have built a stadium in Youzhou, and they are not ready to capture this kind of small building, I heard that two newlywed small buildings have been built.

Speaking of newlyweds, I have to mention Xu Yang's marriage, Liu Dongliang and Old Man Liu discussed for more than ten days, and finally set it for November Ganqi, it is said that it is still the day of Yuan Tiangang's construction, suitable for marriage and travel.

After Xu Yang told the news that he was going to get married, everyone was very surprised, Wei Chi, Chu Mo, and a few of them thought that Guigu would not get married, after all, Xu Yang was twenty-one years old and had not yet married a wife, which was simply unreasonable in the impression of the Tang people.

In the end, knowing that Guiguzi stipulates that men can only get married after they are twenty-one years old, everyone understands and shows a bad smile, after all, a twenty-one-year-old virgin, this is indeed worth laughing at.

Everyone sent congratulatory gifts, and the old man of the Chu Mo family, Cheng Zhijie, had seen Xu Yang, and also knew that Lao Niu was now reading Xu Yang's "Navigation Minutes", so the Cheng family sent a full five boxes of gifts, and the happy housekeeper Liu grinned to the root of his ears.

The Wei Chi family is too, after all, they are good friends with Lao Niu, and Lao Niu's friends are their mutual friends, and they are also five boxes of gold and silver gifts.

Li Jing, Li Xiaogong's family was a little polite, and a box of congratulatory gifts was sent away. However, Wei Zheng's family also sent two boxes of congratulatory gifts, which made Xu Yang praise Lao Wei's character.

Fang Xuanling also sent someone to send five boxes of congratulatory gifts, and the friends Xu Yang knew in the court were basically these few, as for the other nobles, they didn't mean to join in the fun at all, and there was no need for a small county marquis to stammer.

Xu Yang is also happy to be idle, there are not many friends, seven or eight is enough, and he is not planning to be a very good minister, he lives a new life, and living comfortably is the most important thing.

Driving a steam car, Xu Yang was going to drive to the business club in Xishi, and this year, it was enough to park the steam car in the parking lot, and by the way, he discussed coal mining with Li Erma, who was doing health care there.
