I don't know how long it took, Zhu Liang, who was guarding outside, knocked on the door.

"Your Highness, Your Highness!"

Before Guo An and Zhu Fu could react, Zhu Di had already sat up suddenly.

"What?"

Zhu Liang replied: "Your Highness, the manager of the Iron Smelting Institute has reported that the giant iron-making furnace at the bottom of the mountain behind can be opened!" ”

"Very good!"

Zhu Di got out of bed directly, got up and walked out.

Guo An and Zhu Fu, who were still a little confused, also staggered to keep up.

Staying here overnight, everyone is sleeping with their bodies down, no one has taken off their clothes, not even their shoes, and they can go directly after getting out of bed.

When he went out, Guo An heard that Zhu Di was asking Zhu Liang: "What time is it?" ”

"Back to Your Highness, it's the third watch!"

"So late?"

Zhu Di sighed with emotion and walked straight to the back mountain.

"Yawn ......"

Guo An yawned, tugged at his eyelids, and after sobering up a little, he dragged Zhu Fu beside him and hurriedly walked forward.

When they arrived in front of the giant iron-making furnace, a group of craftsmen were already surrounding the iron-making furnace.

Around, torches and fires are lit, and this piece of light is brightly lit.

The eyes of every craftsman are flashing with excitement and expectation.

"Your Highness is here!"

With the arrival of Zhu Di, Zhong Huo and a group of craftsmen hurriedly stepped forward to salute.

"See Your Highness, villain!"

"Get up."

Zhu Di waved his hand, and looked directly at the huge iron-making furnace in the innermost.

"Can you turn on the furnace?"

Zhong Huo replied: "Back to Your Highness, it's been almost five hours, and you can open the furnace!" ”

Zhu Di directly ordered: "Open the furnace!" ”

"The villain obeys!"

Zhong Huo's face was overjoyed, and he turned around and shouted loudly to the craftsmen behind him: "Your Highness has an order, open the furnace!" ”

"Open the furnace!"

The craftsmen were all excited.

As blacksmiths, the iron-making furnace is their breadth.

They had long heard that Guo Xianzun of Wanping County took ten craftsmen and worked day and night to build such an iron-making furnace with a height of two zhang here.

Therefore, they had been looking forward to the time when they could make this giant iron-making furnace have a furnace of iron.

And now, they can finally see with their own eyes that this giant iron-making furnace is making iron, and even helping out on the side, all the craftsmen can't help but feel full of strength.

As an old craftsman opened the bottom taphole, the fiery molten iron flowed out directly.

"Out of the iron!"

"Get on the mold!"

"Go ...... again"

"Upper Cauldron ......"

"......"

Under the gaze of Guo An, Zhu Di and others, the giant iron-making furnace flowed two cups of molten iron.

Fortunately, there are many craftsmen around the iron-making furnace, and they can deal with it calmly.

Zhong Huo also remembered Zhu Dizi's order during the day, when he filled these molten irons, he first used some knife molds to pack them.

So, Zhu Di, Guo An and others saw that every time a mold was installed, a craftsman would take it and leave.

In the distant house, there was a tinkling and thumping sound.

And after there was no longer a drop of molten iron flowing out of the iron-making furnace, all the lights in the surrounding rooms were lit up, and all of them were the sound of hammering and forging.

"Ding Ding Dong ......"

Just when Zhu Di was staring at each room with a curious face, Zhong Huo ran over with a happy face, "Your Highness, the villain just calculated, a total of one hundred and ten rough steel knives, weighing four hundred and forty catties, and three hundred and twenty catties of molten iron, which is seven hundred and sixty catties!" ”

"Seven hundred and sixty pounds of molten iron?"

Zhu Di turned his head violently and stared at Zhong Huo tightly, "Are you sure what you said is correct?" ”

"Back to Your Highness, the villain will never dare to coax Your Highness!"

Zhong Huo shuddered and hurriedly said.

Zhu Di's face turned red at a speed visible to the naked eye, his eyes flashed red, he subconsciously looked at Zhu Fu and Guo An, and said excitedly: "Zhu Changshi, Guo An, a giant iron-making furnace can produce at least 760 catties of iron a day, as long as this king asks the iron-smelting institute to build ten giant iron-making furnaces of this size, wouldn't it be able to smelt 7,600 catties of steel in a day, which is stronger than those pig iron in the past?"

Is it more than 200,000 catties in one month and more than 600,000 catties in three months? ”

Zhu Fu also saluted excitedly, "Your Highness is wise!" ”

Guo An also hurriedly followed the flattery: "Your Highness is wise! ”

"Hahaha, 600,000 catties of pig iron, 600,000 catties, I didn't expect it to be solved so easily."

Zhu Di's face was full of joy and laughed loudly.

No one can know how worried Zhu Di was at the moment he received the holy decree.

Unexpectedly, it has only been a day, and for him, 600,000 catties of pig iron, which is like a mountain, can be solved so easily.

Thinking about it, Zhu Di looked at Guo An, and said with a face full of appreciation: "Guo An, this king has a credit to you in this matter!" ”

Guo An chuckled and said, "Your Highness just remember to give the lower official the one hundred taels of silver!" ”

Zhu Di was a little puzzled, "What one hundred taels?" ”

Guo An's eyes widened and he looked at Zhu Di helplessly.

"Your Highness has not forgotten, a month ago, His Highness bid a hundred taels of silver, and also sent ten old craftsmen to the lower officials, so that the lower officials can develop how to increase the speed of iron smelting."

Hearing this, Zhu Di's face froze, and he remembered.

"It's been more than a month, I didn't expect you to remember it every day!"

Guo An looked at Zhu Di with a serious face: "Your Highness, that's a hundred taels of silver, if the lower official saves some flowers, it will be enough for all the expenses of the lower official for a year!" ”

Zhong Huo: "......"

Zhu Fu: "......"

Li Wang: "......"

Save some expenses, you need a hundred taels a year, do people say?

Zhu Di was furious, "You thief is really extravagant!" If I let those inspectors know about the imperial history, I will definitely have to participate in you again! ”

"Your Highness, these are all earned by the lower officials, why should you be afraid of them?"

Speaking of this, Guo An is full of confidence.

He believed that the matter of iron smelting alone was enough for Zhu Di to pay attention to him thoroughly.

Even if he is removed from power by the inspector Yushi, he can still enter the palace of King Yan, mix things up, and continue to live.

Maybe he'll be safer.

At least, he had never heard that when Lao Zhu was sitting on the throne, he went to kill the officials in the palaces of the feudal kings in various places.

At this time, Zhu Di was still thinking about his steel knives, and he didn't have the heart to talk to Guo An about these words.

In addition, this will be in a good mood, and he said directly: "When the king goes back, he will send someone to give you the one hundred taels, no, the king will give you another four hundred taels, which will be regarded as the king's reward for you!" ”

Guo An shook his head and refused, with a resolute expression, "Your Highness, the one hundred taels that I said before, the lower officials only need one hundred taels." ”

"Huh?"

Zhu Di glanced at Guo An with some surprise, "You thief didn't particularly like money before, why did this king give you more, you still don't want it?" ”

Guo An said: "Your Highness forgives your sins, although the lower officials like money, they also have their own principles. ”

"Whatever you want!"

Zhu Di didn't care so much about this.
