Hearing Guo An's shout, an old craftsman shook his head and body, then slowly turned his head, and after seeing Guo An, he suddenly ran over with a panicked face and saluted Guo An.

"The villain saw Guo Xianzun, the villain should be damned, he only cared about checking the iron-making furnace, but he didn't pay attention to the back, and he didn't know that Guo Xianzun and several nobles were coming."

Guo An smiled helplessly, "I told you a long time ago that there is no need for so many courtesies here." Well, today, His Royal Highness King Yan is here, and you will quickly open the furnace to make iron, and show His Highness the results of this month! ”

"His Royal Highness King Yan?"

The blacksmith was startled, and subconsciously looked at Zhu Di beside Guo An, trembling all over, and hurriedly knelt down to salute.

"Please also ask Your Highness for forgiveness, the villain is blind, has eyes without beads, and I don't know that His Royal Highness King Yan is coming, and I ask His Highness to forgive my sins!"

Beside the iron-making furnace, a group of craftsmen also heard the movement here, and after hearing that His Royal Highness King Yan was also coming, they were all full of excitement at first, and then they all knelt down with a panicked face, and kept kowtowing to Zhu Di.

Zhu Di waved his hand casually and said, "Don't blame those who don't know, wait for it to get up quickly, go to smelt iron!" ”

"Yes, Your Highness!"

The blacksmith got up quickly, and ran to the iron-making furnace with excitement on his face.

At the same time, he shouted: "His Royal Highness King Yan has an order, open the furnace to make iron!" ”

"His Royal Highness King Yan has an order to open the furnace to make iron......"

Hearing the voice of this group of old craftsmen, the blacksmiths who were also busy with other things around them also hurriedly ran over here.

The handling of ore and coking coal moved in a chaotic and orderly manner.

Suddenly, Zhu Di, Zhu Fu and others, who were looking around with curiosity on their faces, heard a sound of 'bang' iron rubbing.

Looking at the voice, Zhu Di's eyeholes couldn't help shrinking, and on the side near the iron mine, a square iron car came out of the same time, like a giant beast, and rushed towards this side.

"Your Highness, be careful!"

Li Wang, who saw this scene for the first time, was directly shocked and his hair stood on end, and his scalp was numb, but he still subconsciously pulled out the steel knife in his hand and protected it tightly in front of Zhu Di.

As for Zhu Di, Zhu Fu and others, they were also nervous.

Only Guo An and Zhu Liang were the only ones, as if they had expected it, they did not panic at all, and looked at the speeding iron car with admiration.

"Knock ......"

With a dull sound, the iron cart did not come at them, but flew directly to the cliff behind the iron-making furnace, and after running forward for some distance, it came to a steady stop.

It seems that it is specially for the iron-making furnace to send iron sand!

"Pour iron sand!"

Before Zhu Di and Zhu Fu could ask Guo An questions, they saw two old craftsmen emerging next to the iron car, one holding a big shovel, shoveling iron sand into the iron-making furnace from the iron car.

"Guo An, what is this?"

Zhu Di's eyes flashed, and he hurriedly asked Guo An.

Guo An replied: "Your Highness, this is an iron car. ”

Zhu Di asked again: "How can these iron cars slide down from the iron mine above so unhindered, and can still stop directly above the iron furnace?" ”

Guo An smiled slightly, pointed to the place where the iron cart had just slipped down, and explained: "Your Highness, there are a few slides built with big iron rods specially for these iron carts.

As long as you load the iron car with iron sand and gravel on the top, and then send the iron car to the slideway, and gently push, the iron car can slide all the way down the slideway to the designated place! ”

"How can there be such an amazing slide?"

Zhu Di and Zhu Fuji's eyes widened directly, and their faces were full of incredulity.

The speed and weight of the iron cart rushing down just now can be regarded as a wave of direct face-to-face feeling, the speed and weight, even if ten chariots are blocked in front, it can't be resisted, how can it be controlled with just a few iron rods to build a slide?

Thinking about it, Zhu Di walked directly in the direction of Guo An's finger.

Sure enough, after a few steps, I saw a concave road connected by eight iron rods, and there were shiny friction marks on the iron rods, which extended all the way up the mountain.

Then follow the slide in the direction of the iron-making furnace.

The chute made a turn directly under their feet, down the slope to the rock face at the top of the furnace.

Seeing this, Zhu Di and the others only thought about it slightly, and then they understood, and their faces were full of appreciation.

"With this kind of slide and iron car, from now on, there will be no need for craftsmen and laborers to carry iron sand from the mountains to carry baskets and baskets of iron sand.

The mining speed of the entire iron ore mine can be increased by at least ten times! ”

Guo An replied, "Your Highness is wise! This method can also be used for other minerals, especially coal mountains! ”

"Exactly!"

Zhu Di's face was full of red light, looked at Guo An and asked, "Who came up with such a trick?" This king will give him a great reward! ”

Guo An smiled and replied: "Your Highness, it is the lower official!" ”

"You?"

Zhu Di's face stiffened slightly, and he walked towards the iron-making furnace.

"Your Highness, you haven't told your subordinates yet, what do you want to reward?"

Guo An was stunned and hurriedly asked.

Zhu Di pretended not to hear it, and looked at the old craftsmen with interest, busy around the iron-making furnace.

Guo An's face turned dark, and Zhu Laosi wanted to repay the debt.

At this time, Zhong Huo, the manager of the Iron Smelting Institute, who heard the report from his subordinates, ran over sweating profusely.

"The villain Shangzhuang Village Iron Smelting Institute manager Zhong Huo saw His Highness, the villain didn't know that His Highness was coming, and he missed the distance, and asked His Highness to forgive his sins!"

Zhu Di glanced at Zhong Huo, who was sweating profusely and his face was still black and muddy, and said directly: "It's okay, get up!" ”

"Thank you, Your Highness!"

Zhong Huo hurriedly got up and waited respectfully to the side.

And this time, the iron car above the iron-making furnace was pulled up the mountain with a 'bang'. The iron car had just landed on the iron ore, and there was another dull sound on the slide.

An iron cart loaded with iron sand rushed down from the iron mine again and landed firmly above the iron-making furnace.

Just now, the two old craftsmen appeared again, and quickly filled the iron-making furnace with iron sand.

In this way, it has been repeated seven or eight times, and the old craftsman who has changed three stubbles has been replaced, and the old craftsman on the cliff wall has closed the iron-making furnace and come down from above.

And in the stove under the iron-making furnace, the fire was already burning, and Zhu Di, Guo An and others also subconsciously took more than ten steps back.

Zhong Huo, who had not spoken, flickered his expression, then bowed to Zhu Di and said, "Your Highness, if this iron-making furnace wants to make molten iron, it will take at least four or five hours, Your Highness might as well go to the lobby to rest for a while and drink tea?" ”

"Huh?"

Hearing this, Zhu Di's face sank and he glared at Guo An on the side.

"If this iron-making furnace wants to make molten iron, it will take at least four or five hours?"

Guo An didn't know what was wrong with Zhu Di, and the girls in later generations were not so fickle, but he still slowly replied: "Back to Your Highness, it should be like this!" ”

Zhu Di looked at Guo An unkindly: "Then you, the thief official, brought this king all the way to come to see this big iron furnace and the iron car?" ”

Guo An was puzzled: "Your Highness, this is not enough?" ”
