On the other side, the prince's mansion was closed, and Li Jiancheng really couldn't come out and couldn't see anyone, but his crown princess Zheng took Li Jiancheng's handwritten letter to return to her parents' house in the name of returning to her parents' house, and arrived at the Zheng family's mansion in Chang'an in Xingyang. Pen & Fun & Pavilion www.biquge.info

Zheng Yuanxuan of the Zheng family sat in the first place, he was a high-ranking official when he was in the former Sui.

During Li Yuan's anti-Sui period, he raised the city and surrendered, and is now Taichangqing, a high-ranking official of the third grade.

Sitting in the first guest seat under Zheng Yuanxuan is Cui Junsu of the Qinghe Cui family, who is currently the squire of the military department. Further down is the Boling Cui clan, Cui Dunli is currently the general secretary of the province.

Another guest, Taiyuan Wang's Wang Jun's stunned, Longxi Li's Li Yanshou.

Further down, there are the younger generations headed by Cui Yiye.

"Wang Junkuo was originally a bandit, a person from the original Qin Palace, this matter is treacherous." It was Wang Jue who spoke, he was not optimistic about people like Wang Junkuo, and he always caused some unnecessary trouble to the prince's mansion.

"But, why did Wang Junkuo kill King Qi?" Cui Dunli asked.

Wei Zheng, who was sitting at the bottom, got up: "It may not be that Wang Junkuo killed him, it may be someone else, who killed him together with Wang Junkuo." ”

"But the forbidden army saw with their own eyes that Wang Junkuo and His Royal Highness the King of Qi were fighting viciously, and the corpse was indeed Wang Junkuo's personal soldier, and he was indeed dead at that time." Zheng Yuanxuan asked rhetorically.

Wei Zheng wanted to say something more, but Wang Jue stopped him: "What is the result of the death of His Royal Highness the King of Qi?" ”

"This question still needs to be asked, and the prince needs to bear this responsibility. On the surface, the prince just didn't investigate, but because of the death of His Royal Highness King Qi, there was a sense of covering up the facts, which made His Royal Highness the Prince very passive. Everyone agrees with Choi's words.

Only then did Wang Jue say: "This is the conspiracy of the Qin Palace, no matter who it is, whether it is Wang Junkuo or someone else, the result is the same. ”

At this time, a scribe sent the third edict.

After Wang Jue saw it, he held the eldest person in front of Zheng Yuanxuan with both hands: "Zheng Gong." ”

"That's how it is." Zheng Yuanxuan was taken aback.

Without waiting for everyone to ask, Zheng Yuanxuan said: "Liu Mu, a small people, but he directly entered the official position under the five grades. Either it is a holy grace, or it is a miracle, just because marrying the princess and the old husband thinks it is not enough to get from the five grades. Since the first year of Wude, the promotion and depreciation of the DPRK and China have been extremely fair. ”

The edict was spread by everyone, and they were all secretly amazed.

"So what is this miracle?" Wang Qi is not asking everyone, but himself.

"Let's see." What Zheng Yuanxuan means by this is that if you wait and see, there will definitely be a result in this matter, since it is a holy edict, such a promotion needs to be recorded, so there must be a reason.

The Tang Emperor is not in Chang'an at the moment, and this filing can be suspended, but it will definitely not be discontinued.

"Tiance Mansion, he is really King Qin's person." Wei Zheng sighed with emotion.

"Go and check if King Qin has asked for a seal for him." Zheng Yuanxuan said to Wei Zheng, because Wang Jue is going to be demoted outside Chang'an at the moment, and everyone is trying not to be degraded too far.

At the moment, the representatives of these old nobles continued to discuss the impact of the current Qin Wangfu Supervision State, as well as the strategy to deal with it.

Wei Zheng was in charge of verifying the matter of Liu Mu.

In a ravine somewhere in Huayuan County, Yaozhou.

Li Dejian has lost the demeanor of a noble son, and he wears a stone velvet cloth, which is also called Huohuan cloth. It has been recorded as early as the Zhou Dynasty, and it has been widely used in the Han Dynasty.

The purpose of this cloth is to prevent fire.

When the Tang Emperor Li Yuan arrived, Li Dejian was still holding a copper horn and shouting at the craftsmen.

Li Yuan motioned not to disturb, so he let Liu Mu and Peng Hai stand beside him and watch the workshop from afar.

"This is a Han-style blast furnace." Li Yuan was extraordinary, and he could see the essence of this furnace at a glance. Liu Mu explained, "The saint just looks at the elephant, but the inside is different. ”

"How is it different?"

"The furnace of the Han Dynasty used clay, but this furnace is made of a kind of soil that is a specialty of Huayuan County, called refractory bricks, and the bricks will not be burned out when the iron is turned into molten iron. And there must be in the furnace, as well as the feldspar that is a specialty here, cut the feldspar into strips and placed in the furnace. ”

"Yes." Li Yuan nodded and continued to watch.

Liu Mu is not an engineering man, he doesn't have detailed engineering drawings, it's simple and okay, this kind of high-tech thing Liu Mu can't.

But willow wood knows, coke, feldspar, refractory bricks.

The two old blacksmiths kept observing the stove from the high shelf next to them, and one of them raised the flag in his hand, and the other was still observing, that is, after a few minutes, he also raised the flag in his hand.

"Hanging the cable ......" Li Dejian focused on the stove and didn't notice that the Tang Emperor had arrived.

Two on both sides, two on the back, and one on the front.

Under the strength of dozens of people, the four cables slowly tilted the furnace, and the molten iron flowed out of the furnace, and it was one sand mold after another, and the molten iron was not poured into the sand mold.

After about a quarter of an hour, the furnace was emptied of molten iron.

The laborers began to clean the furnace, and the new feldspar and the crushed ore were brought closer, as well as the large amount of coke that had been prepared long ago.

"Weighing." Li Dejian couldn't wait to ask for a weighing.

He wanted to know how much of this furnace came out and what was the condition?

Then retrain again with another furnace to refine the impurities. Then change to the last furnace, which can be turned into molten steel.

The people who could enter the last workshop were all the ones who signed the death contract, and even Li Dejian could not go to the last workshop, where the top assassins were responsible for guarding the surroundings.

Because Liu Mu said that the purest is wrought iron, and the impure is pig iron. Steel is made from carbon to produce wrought iron with a very small amount of charcoal.

The iron bars taken out of the sand mold were still dark red, and the craftsmen were as anxious as Li Dejian, they couldn't wait for these iron bars to get cold, so they used big pliers to clamp them together and put them on the graphite tray, and on the other side there was a standard one-pound iron block, and then according to the weight change, the standard one-dollar weight was used to counterweight it.

"You don't need to count decimals, count how many there are." Li Yuan spoke.

The craftsmen didn't know who Li Yuan was, but they knew Liu Mu.

Looking at the color of the Tang Emperor's costume, it is very gorgeous. The people who still wear silk in this workshop are definitely nobles. And judging from the position, it seems to be taller than Yanagiki, the biggest figure.

Li Dejian reacted, just looking at the clothes, he knew that this was the Tang Emperor in person.

Li Dejian stepped forward to give a salute, and Tang Emperor Li Yuan waved his hand: "No courtesy, stand aside." ”

An iron bar weighed five pounds, and it was quickly counted seventy-one and a half. That is, this furnace has three hundred and fifty catties.

"Good." Li Yuan nodded with satisfaction and asked, "How long does it take for a furnace?" ”

"Back to you, saint, this furnace will take about an hour."
