"Lord Ling, is it done? You are so happy. Li Wu asked Ling Jing who ran over.

"Good stuff, absolutely good stuff." Ling Jing's face was full of wrinkles with a smile.

"Wait! The Lord is just tame the wind! ”

As soon as Li Wu's words fell, he saw Guo Qi riding the wind and running over to this side.

"Phew, hoo, hoo......" Guo Qi tightened the reins and stopped chasing the wind.

Getting off the horse, Guo Qi threw the reins to Li Wu and "hissed" to take a breath.

Ling Jing saw that Guo Qi's legs were already stained red with blood, and asked Guo Qi anxiously, "Lord, what's wrong with you?" ”

"It's okay, chasing the wind is too good to toss, and it just wears out the thighs."

"Ma Jiu didn't hurry up and call the military doctor, a few of you will carry the lord into the house." Ling Jing immediately commanded.

After the military doctor came over and read it, he said: "The lord is not in any big trouble, but he has broken the horse, and it will be fine for a few days with gold sore medicine." ”

After the military doctor left, Guo Qi asked Ling Jing: "Running over in such a hurry, and shouting 'It's done' just now, what is it?" ”

"Look, my lord." Ling Jing said as he took a wooden box from the hand of the attendant and opened it, only to see a war knife in the box; "Lord, this war knife is made of steel-filled iron, and I have tried that even the fine iron war knife we use now can be split in half, and there is no damage."

"What you said is true?" Guo Qi asked in disbelief.

"Lord, if you don't believe it, you can try!" Ling Jing said very confidently.

"Okay, then the king will try, if you dare to deceive the king, the king will not spare you." Guo Qi scolded with a smile: "Fifth son, pull out your war knife and fight against this king." ”

"No!"

Guo Qi took out the steel-filled war knife in the box, walked outside and fought against Li Wu, the two of them gently collided with each other with the war knives in their hands, and then slashed together, only to hear the "bang", the war knife in Li Wu's hand became half, Guo Qi felt that his tiger mouth was numb; Guo Qi hurriedly withdrew the war knife and looked carefully at it, except for a small gap on the blade, the rest of the place was intact.

"Good knife, really good knife!" Guo Qi looked up to the sky and laughed loudly: "Fifth son, go and prepare horses, this king will go to Baili City now." ”

"No! Humble and prepared. Li Wu was equally excited.

Chasing the wind has been tamed by Guo Qi, Ma Jiu took a set of good saddles and stirrups on the body of Chasing the wind, Guo Qi took Li Wu and others to lead more than 100 cavalry to the north and went straight to Baili City; Due to the speed of the cavalry, although the mountain road was relatively difficult to walk, it only took two hours to arrive.

"Phew, hoo, hoo......" came to Baili City, Guo Qi just grabbed the reins, chased the wind and raised his front hooves to stand under the city.

"Who is under the city? Get out of here, or we'll have to fire our arrows. The sergeant guarding the Baili Pass shouted loudly.

"Yongwang Guo Qi, quickly open the city gate."

"Is there a token instrument?"

"It's all in the hands of the guards behind!"

"Then wait for your guards to come and open the door! Get out of the way of an arrow, or we're going to let it go. ”

Guo Qi had no choice but to retreat to a distance and wait, and after waiting for about a quarter of an hour, Li Wucai led the follow-up men to arrive, and when he saw Guo Qi outside the city, he immediately couldn't run and asked: "Lord, why don't you enter the city!" ”

"If I can get in and wait here, hurry up and call the city gate."

Li Wu walked to the city and showed his token, the gate of Baili City was finally opened, and the officers guarding the city immediately came to ask for guilt: "I don't know that the prince is coming, please punish the prince." ”

"What a sin to be conscientious in one's duty; If you open the gates of this king today, this king will punish you. After Guo Qi finished speaking, he patted his horse and went into the city.

Although it has not been a few days, Baili City has changed greatly, the original low and dilapidated houses have been repaired, the military camp and the iron mill have also been built, and the visit has been strictly planned; The ironshop is not as dirty and messy as it used to be, and it is very tidy.

Guo Qi came to the iron mill and dismounted, and walked towards the iron mill on foot, the iron mill was still as hot as before, the original low iron furnace was gone, and all of them were replaced by high-speed iron furnaces; The blacksmiths in the blackworks are working shirtless and shouting slogans!

Guo Qi's arrival did not affect the work of the blacksmiths, and Guo Qi did not disturb them, and took Li Wu to inspect around, only to see Tie Shan standing not far away and directing several craftsmen to be busy.

"Fast, fast, fast...... Place the raw iron (Note 1) in the filling tank. ”

"It's all set."

"It's time to open the furnace!"

Iron Mountain gave an order, the hot molten iron flowed out of the blast furnace along the furnace trough, and the original iron that was originally placed in the trough was melted instantly, and while the molten iron was not cooled and solidified, several men lifted the trough made of stone and poured it into another trough, and went back and forth three times before stopping; The molten iron is poured one last time into a double stone trough with cold water between the inner and outer troughs, which can be replaced back and forth to speed up the cooling.

After some busyness, Tie Shan turned around and saw Guo Qi, and hurriedly saluted: "The villain greets the prince." ”

"Hurry up, please." Guo Qi personally helped Tieshan up and asked, "After this king watched the molten iron melt the original iron just now, why are you still pouring back and forth in the irrigation trough?" ”

"Lord Wang, this raw iron cannot be evenly distributed immediately after being integrated, so after pouring it back and forth in the filling tank three times, the molten iron and the original iron can be fused more evenly."

"How many catties of steel-filled iron can be smelted from this furnace of molten iron?"

"It's only a hundred pounds at most."

"And how many days does it take for this molten iron?"

"It takes about three to four days, depending on the temperature in the furnace."

"That is to say, this furnace can smelt thirty catties of steel-filled iron in one day, just now this king took a look, you have a total of eighteen blast furnaces here, and there are more than five hundred catties of this day, too little."

"How much does the prince want to practice in a day?"

"This war knife costs fifteen catties of fine iron, and you can build thirty or forty pieces of this day, not counting armor, arrows, spears, etc., so it will be at least ten times more expensive." Guo Qi thought for a while and said.

"Ten times, that is, five thousand catties of blast furnaces should be refined in one day, that is, one hundred and eighty blast furnaces." Iron Mountain exclaimed.

"This king is not for you to reach immediately." Guo Qi said with a smile: "Since you have refined this steel-filled iron, this king has also fulfilled his original promise and appointed you as a first-class public servant and a weapons supervisor, who is specifically responsible for iron-making matters." ”

"The villain worships the prince, the prince is a thousand years old, a thousand years old, a thousand years old." Tie Shan immediately knelt down and said.

"You are not a villain now, and the king's ministers should call themselves lowly." Guo Qi said with a smile: "Tieshan do a good job, this king is optimistic about you, after the iron mill, it will be baked according to five thousand catties per day, you want the king to give you people, and the king will give you money, and the king will have a requirement, to achieve this goal in the shortest possible time, and at the same time, the quality of steel and iron can not be reduced." ”

"If you accept orders from humble duty, you will live up to the trust of your lord." Tie Shan said solemnly: "My lord, when I was refining and filling steel, I also accidentally smelted another kind of refined iron, but this kind of iron is very good when it is beaten into thin sheets, and it is not easy to break......
