Li Shimin

Then, he looked at Li Xuan suspiciously.

"Open the furnace and make iron!"

Li Xuan said.

"Yes!"

After hearing this, Ying Qi and Wu Fu quickly put down the glass in their hands and ran to the larger stove in the corner.

At the same time, Cheng Chusi and Yuchi Baolin had already entered with two carts.

The cart is filled with iron ore.

As for Li Chengqian and the others, they started to light fire and blow wind.

Each does his own thing, well organized.

Only Li Xuan stood aside, not moving a muscle.

Li Yuan stared at Li Xuan for a long time, his eyes full of doubts.

"I have led them to practice several times in making iron. Therefore, I just need to watch and don't let them make any mistakes!"

Li Xuan chuckled and explained slowly.

And this time, the iron-smelting furnace has begun to operate rapidly.

On one side, under the pull of the blower by Li Chongyi, the temperature inside the forging furnace has been rising.

Less than a quarter of an hour.

The entire forge has started to heat up.

As for Li Chongyi and the others, they had already taken off their sheepskin jackets and put them in a row of wooden boxes in the corner.

The same is true for Li Yuan and Li Xuan.

The clothes on his body are thin, can you still see the hideous scars on Li Xuan's arms?

"It will take a while to melt the iron ore, why don't you go back to the house to rest for a while, come back in half an hour, it's almost ready!"

Seeing that Li Yuan was sweating profusely, Li Xuan suggested.

"No, the old man is waiting here!" Li Yuan waved his sleeves with a firm expression on his face.

Immediately, he still stared at the iron-smelting furnace that was nearly two people tall.

Seeing this, Li Xuan turned his head and glanced at Li Chengqian who was at the side.

Li Chengqian ran out quickly, and soon came in with four small horses in his hands.

Then, put one under Li Yuan's buttocks.

Li Yuan was also polite and sat down directly.

Cheng Lao Si and others who followed in beside him sat cross-legged on the ground.

If Li Yuan didn't leave, Li Xuan was naturally embarrassed to leave.In the past, they always left the two of them to smelt iron, and took turns to take over after a quarter of an hour.

However, if Li Yuan didn't leave here today, they could only take them in the forge, like a sauna, and waited for half an hour.

"Master, it's almost time, it's time to start the furnace!"

Half an hour later, Li Chengqian said to Li Xuan.

After hearing this, Li Yuan was refreshed, but soon looked at Li Xuan with some doubts, did he finish training so quickly?

"Open the furnace!"

Li Xuan didn't pay attention to Li Yuan's questioning eyes, stood up straight, and said slowly.

"Yes!"

Li Chengqian replied.

He gestured to the two craftsmen Ying Qi and Wu Fu beside him.

Wearing thick gloves, the two of them came to the iron furnace and skillfully opened the furnace.

Immediately, a stream of fiery red molten iron slowly flowed out of the furnace.

After all the iron juice flowed out, the two-foot-square container on the ground was nearly half full.

"Your Majesty, this is definitely pig iron!"

Seeing this, Cheng Laosi and the others beside him couldn't help but stare with big eyes and their faces were full of excitement.

"It's pig iron, and it's pig iron with good quality!"

Li Yuan was also full of excitement, shaking his body slightly, "In just one hour, a furnace of molten iron was smelted. This kind of iron smelting method is really amazing!"

"The Supreme Emperor, Your Highness the Crown Prince, Saburo, this furnace of pig iron weighs 120 catties!"

By now, Ying Qi and Wu Fu had already weighed out the pig iron in the container.

"220 pounds?"

Hearing this, Li Yuan couldn't help but widen his eyes.

"It's really 220 catties?"

Ying Qi and Wu Fu looked terrified, and they quickly clasped their hands and replied, "I dare not lie to the Supreme Emperor, this furnace of pig iron definitely weighs 220 catties, not less than a catty!"

"Haha, good, good..."

Li Yuan burst into ecstasy, his face full of joy.

Behind him, Cheng Laosi and the others were also overjoyed.

"In this way, one thousand catties of pig iron can really be forged in one day!"

After Li Yuan finished venting, he said to Li Xuan excitedly: "Don't worry, Xuanba, as long as you inform the Ministry of Industry and the Military Supervision of this iron making method, let alone 230 iron stoves, even if you want to forge For two thousand iron furnaces, the officials from the Ministry of Industry and the Military Weapons Supervision will rush to forge them for you!"

Afterwards, Li Yuan circled around the freshly solidified iron juice twice, and said directly to Li Chengqian: "It's not too late, Gao Ming, you should go back to the palace quickly and tell Yu Erlang about it!"

"Yes, Grandpa Huang!"

Li Chengqian hurriedly cupped his hands in salute.

Then, he said to Li Xuan: "Master, Gao Ming will go back to the palace first."

"Hurry up, remember that there are 230 iron stoves, and each iron stove must be equipped with a three-foot-long iron tube!"

Li Xuan nodded lightly. As for the iron making method that he tested for several days, he just gave it to Li Shimin, he didn't mind at all.

"Yes, Master!"

After saluting again, Li Chengqian hurried out.

"Master, I want to go with Gao Ming!"

At the side, Cheng Chusi also stood up suddenly and bowed his hands in salute.

"Go, Li Chongyi will go too!" Li Xuan said.

"Yes!"

Immediately, Cheng Chusi and Li Chongyi walked out of the forging workshop quickly, and then, like wild horses that had run loose, ran happily to the outside of Li's Village.

Just following Li Chengqian to Chang'an City, the two of them felt a sense of excitement like a holiday.

……

Chapter 133 My son has something urgent to report!

Then, the two passed Li Chengqian and ran directly towards Chang'an City.

The heavy snow just fell yesterday, and the two of them ran on the road, running wildly for a certain distance, and then stopped to slide forward.

In this way, when they were tired from running, the two stood by the roadside, waited slowly for Li Chengqian's carriage to come, and sat on it.

……

Inside Chang'an City.

After hearing Li Wei's order, Zheng Ye, the supervisor of the Shaofu, ordered the craftsmen to start forging the large iron furnace, while running into the palace anxiously.

Twenty large iron stoves must be matched with a sixty-foot iron stove, which requires at least two thousand four hundred catties of pig iron.

However, although the Shaofu Supervisor is in charge of all kinds of crafts and skills, there is only two thousand catties of pig iron left in the treasury, which is not enough to forge so many iron stoves.

"Not enough pig iron?"

In Liangyi Hall, after hearing Zheng Ye's report, Li Shimin was surprised.

"There are only twenty large iron stoves, and a majestic young mansion supervisor, but there is not so much pig iron?"

"Return to Your Majesty, I dare not lie, there are indeed only two thousand catties of pig iron in the prison of the Shaofu!"

Zheng Ye quickly replied.

"Isn't two thousand catties of pig iron enough?"

Li Shimin's eyes widened, and then he couldn't help but think of something, and asked quickly: "Zheng Ye, how much pig iron is needed to forge a large iron furnace?"

"Return to Your Majesty, one hundred catties of pig iron!"

Hearing Li Shimin's question about the reason, Zheng Ye felt relieved, and continued, "Your Majesty, each large iron stove needs twenty catties of pig iron to equip a three-foot iron cylinder!"

"hiss……"

Hearing this, Li Shimin looked startled, took a sharp breath, his eyes were full of distress.

"Such [-] iron stoves require [-] catties of pig iron!"

"Your Majesty is wise!"

Zheng Ye cupped his hands and replied.

In my heart, I finally breathed a sigh of relief.

Now, His Majesty should not consume so much pig iron to forge those twenty useless iron stoves!

"However, the Supreme Emperor asked me to forge ten large iron stoves for him yesterday!"

But he didn't want to, Li Shimin frowned again, and said softly.

Hearing this, Zheng Ye trembled subconsciously.

The emperor?

"Your Majesty, His Royal Highness, please see me!"

Just when Zheng Ye and Li Shimin were both embarrassed, an inner servant walked in from outside the hall and reported.

"Gao Ming is back?"

Li Shimin was taken aback for a moment, then quickly said, "Let him in quickly!"

After a while, Li Chengqian hurried in.

"My son has seen his father!"

"Gao Ming, shouldn't you be in Lijiazhuang at this time? Why did you come back in such a hurry?" Li Shimin asked directly.

"Go back to the emperor, my son has something urgent to report!"

Li Chengqian glanced curiously at Zheng Ye, the supervisor of the Shaofu with a bitter face beside him, and said to Li Shimin.

"Your Majesty, Your Highness, I will take my leave first!"

During this period of time, Prince Li Chengqian and the Supreme Emperor ran to Lijiazhuang in the south every day. All the ministers and dignitaries in Chang'an City basically knew about it.

Therefore, seeing Li Chengqian looking so anxious, Zheng Ye subconsciously wanted to slip away.

Still, not a few steps away.

I heard Li Chengqian say: "Father, this matter is about the method of making iron!"

Immediately, Zheng Ye seemed to have taken root under his feet, and could no longer walk.

Coincidentally, Li Shimin also said: "Since it is about the method of making iron, Zheng Jiancheng might as well listen to it!"

"Yes, Your Majesty!"

So, Zheng Ye walked back quickly.
