"Host, Cardinal Girl, sit down, ready to put the row." As An Lushan spoke, he untied the rope tied to the bamboo raft, and the bamboo raft followed the stream.

After the creek was dammed to raise the water level, the water depth was about three feet, enough to bear the weight of bamboo rafts and iron ore, An Lushan seemed to know that someone was patrolling, and tied two bamboo chairs to a bamboo row, Zheng Peng and the red bird could easily sit on it, An Lushan had no place, but stood aside as a guide.

Behind Zheng Peng, there is also a long row of bamboo rows, all of which contain bamboo baskets filled with iron ore.

Sitting on the bamboo raft in the stream, with green trees, stones of different shapes and colorful flowers on both sides, it seems that you have entered a picture scroll, especially when the breeze with the fragrance of flowers and plants blows by, that feeling is even more pleasant.

"The mountains and rivers here are beautiful, and it is a good scenery when it is poured." Zheng Peng couldn't help but sigh.

An Lushan immediately said: "In this kind of poor countryside, there are only mountains and rivers left. ”

Zheng Peng smiled when he heard this, different people have different encounters, and different encounters create different moods, he is interested in this quiet environment, and An Lushan is yearning for a prosperous life.

"Bear with me and do a good job, it's only temporary here." Zheng Peng comforted.

An Lushan realized that he had inadvertently complained, and immediately responded: "Understood, the owner, the little one must do his best to do his part." ”

Zheng Peng nodded and diverted the topic: "How much iron ore can be mined in a day now?" ”

"Now there are relatively more impurities in iron ore, and they need to be screened and scoured when they are dug out, and eighty stones of iron ore can be mined a day, which is equivalent to a good match, and the mining volume can be further improved." An Lushan knew that Zheng Peng would definitely ask this question, so he made preparations early.

One stone is equivalent to fifty-three kilograms in later generations, and eighty stones is more than four tons, which sounds like a lot, but this output is the result of the efforts of more than 300 people, and on average it is pitiful.

This is only the primary ore, which will be significantly reduced after refining.

Zheng Peng frowned and said: "There are so many people, the output is only so little, no, within a month, it will at least double." ”

People eat Ma Jue, hundreds of people just eat a lot of food every day, the efficiency must come out, if the cost of their own mining is higher than procurement, then what else to dig.

An Lushan's face tightened, and he hurriedly said: "Don't worry, the owner has a lot of ideas, and he will definitely be able to increase the output and ensure that the task of doubling will be completed within a month." ”

Whether it is done well or not, it is not the mine slaves who have the final say, nor do they have the final say, but the owner has the final say, since the owner is not satisfied, it must not have been done enough, some time ago An Lushan's mind was on transportation, now think about it, you have to put your mind on the output, as long as the output is up, you can hold your head up in front of Zheng Peng.

"Oh, is it? If you have any new ideas, let's hear them. Zheng Peng became interested all of a sudden, anyway, sitting on the bamboo raft, he was idle.

An Lushan hurriedly put forward his plans for how to improve tools and assign tasks, and soon discussed with Zheng Peng enthusiastically, and the conversation was very popular, and he also took out a charcoal pen and discussed it while drawing on paper.

Before you know it, the bamboo raft arrived at Wangniudun, and in front of the newly built embankment, someone took a long bamboo hook and rope and pulled the bamboo raft to the shore.

The cardinal was surprised to see that there were several wooden frames more than two feet high on the shore, and there was a long and big wooden pole on it, when the bamboo raft transported the iron ore, the wooden pole would turn to the top of the bamboo row, as long as the basket was tied to the hook hanging down above, the two people at the other end of the wooden pole lifted the heavy basket with a little force, pulled the pole and turned, and a basket of heavy iron ore was easily lifted, directly placed on the carriage waiting next to it, and then it was pulled away and pulled to the several high, still smoking iron-making blast furnaces.

"Fat man, this method is really good, saving time and effort." Cardinal said with some surprise.

"Hehe, these methods were all thought up by the owner, and the small ones don't have the same brains as the owners." An Lushan did not dare to take credit and immediately made a clarification.

The cardinal let out an "oh" and quickly fell silent.

No matter what, as long as it involves his aunt, nothing is impossible, and Cardinals are used to it.

Zheng Peng looked at Wangniudun with satisfaction, nodded, and said with a smile: "Let's go, let's see how Blacksmith Liu has done here." ”

When he was in Tiegouling and Chengzhupai, because the output of iron ore could not go up, Zheng Peng's face was slightly serious, and after arriving at Wangniudun, his expression finally improved a lot.

The creek was blocked by a new embankment, and the water level rose, and at the outlet of the embankment, a large windmill nearly three feet high staggered, and the large windmill creaked and turned under the rush of the stream, and carried the water to a small canal next to it, which led the water to the place where the iron was made.

In addition to the big windmill carrying water, there is also a simple gear transmission on the shore, Zheng Peng can clearly hear the sound of hammering in a shed on the shore, the sound is very regular, and when you hear it, you can know that it is using water power to drive the forging.

"I don't know if the young master is here, and I will miss it." Liu Tietou, the blacksmith in charge of Wangniudun, heard the news and hurried to see Zheng Peng.

"I don't know if it's a crime, Liu Tietou, you are also an old man, you know the character of Young Master Ben, don't be so polite, get up."

Liu Tietou was originally called Liu Blacksmith, because of his good craftsmanship and high ability to do things, after he was promoted to the leader, everyone called him Liu Tietou, who was the second batch of old people who followed Zheng Peng, and he helped when he built the Yingshu Bridge, and the iron smelted by his hands was far better than others, especially after Zheng Peng's guidance, the blast furnace was used to make iron, the temperature was increased, and the treatment of impurities was also higher than the industry level of ironmaking in the Tang Dynasty.

"Yes, young master." Liu Tietou knew Zheng Peng's temper, and he no longer insisted.

"Liu Tietou, you are responsible here, take us to visit first." Zheng Peng immediately entered the working state.

"Young master, please here" Liu Tietou made a gesture of invitation to Zheng Peng.

Liu Tietou is a person who does practical things, and soon carried out his work and began to talk about Zheng Peng:

"Young master, the embankment is one foot and five feet high, and it is all used to fill the iron cage with stones and push it to the bottom of the river, and then fill it with mud, which is very firm, the person who repaired the embankment said, with reference to the local mountains and rivers, the water volume of this creek is not large, as long as the sluice gate is fully opened, it can be resisted even if it is a flood once in 30 years, I wanted to cement reinforcement, but I discussed it with the person who repaired the embankment, and the cost of building it again is also very low, so I decided not to strengthen it."

"The big windmill is two feet eight feet high, which can lift water to the canal dug in advance, and can also use the momentum of water to drive the three-handled sledgehammer of the tempering workshop on the shore, which can be used day and night, saving a lot of manpower and animal power."

"Wujin stone to be transported from the back mountain, in order to save trouble, let the nearby villagers transport it on their behalf, each stone of Wujin stone to give three pennies foot money, it is a good to sell the surrounding people, after all, we are here to make iron, the movement is not small, is conducive to a good relationship."

"Young master, the blast furnace is here, now three blast furnaces have been built, and two more are going to be built later, and now the main work is to do testing, that is, to find a kind of iron material that is hard enough, good load-bearing, and not easy to break and deform, and use different heat and ingredients to do experiments, but the progress is a little slow, please give the young master a little more time."

"This is the dining hall, the laborers can sit here comfortably to eat after their work, and they are also pretending to be cool quickly, as long as they change the shaft, they can be driven by water power, which is convenient, or the young master is kind-hearted and kind to his subordinates, and they all read the young master's good."

Liu Tietou took Zheng Peng to visit, and introduced that Zheng Peng had something he didn't understand or didn't understand, and occasionally interjected a few words, and most of the time Liu Tietou was explaining.

After turning around, Liu Tietou's lips were a little dry as he spoke, and after the introduction, he said respectfully: "Young master, the situation here is basically like this, if there is anything that is insufficient, please correct the young master." ”

This is not Liu Tietou's intention to pat Zheng Peng's ass, but out of sincerity, you must know that Zheng Peng casually pointed out a few words to let Liu Tietou take many detours, for Zheng Peng, Liu Tietou not only has respect for the top, but also respects Zheng Peng's knowledge.
