Lin Feng's expression was relaxed when he saw the guy coming up, and he speculated in his heart that it might be Sun Cuo's breakthrough in studying coke and steelmaking. Lin Feng pulled Chen Fei and asked him to go to King Zheng's mansion and ask Li Qiang to come over again.

As expected, the guy ran two steps and said, "Lord Lin, Master Sun's family invited you to come over, saying that there is good news." ”

"Ha Lu Ha, Xie Lu Xie little brother. Let's go. Lin Feng hurriedly hugged the maid and let their brothers and sisters eat by themselves, but he didn't care about fatigue, and hurried to King Zheng's mansion with the guy named Zhang Yongde. Just crossed the corner of the street, and happened to meet Li Qiang driving here.

Hurriedly getting into the car, Lin Feng ordered to go to Sun Ji Iron Shop, and fell asleep. At the end of the day, he was really tired.

"Brother Lin, wake up." Lin Feng was shaken awake in a daze, he tried hard to open his eyes, and found that it was Sun Cuo in front of him. At this time, Sun Cuo's body and face were black and white, his hair was scattered, and the right front of his head was scorched, forming a pit.

"Alas, Brother Sun, don't work too hard." Lin Feng pointed to the scorched place in Sun Cuo's hair, "Did you get roasted once?" ”

"I'm not a duck, you've only been roasted once! Come down, I've got something good for you. Sun Cuo scolded with a smile and dragged Lin Feng out of the car.

Lin Feng followed Sun Cuo into the store, and found that the inside had completely changed, with stoves of different heights and sizes all over the yard, and the whole place was like an African savannah full of termite nests.

Sun Cuo ran into the house on the north side and pulled out two swarthy things like a treasure.

Coke appeared more than 300 years in advance? Lin Feng used the dim candlelight to repeatedly weigh the two pieces of coke in his hand. Lighter than a lump of coal, the body is full of tiny pores, reflecting a cold light in the candlelight.

"This coke is obviously more resistant to burning than coal, and it doesn't smell much. I tested 17 furnaces in a row, and found that the coke quality of the furnace was the best. Now they have been put into seven steel-making furnaces, and they are constantly refining. Sun Cuo said excitedly.

"Did you write down the firing time, the size of the fire, and the capacity of the furnace?" Lin Feng hurriedly asked.

"Noted down. I've memorized each of these furnaces in detail. Sun Cuo took an account book from a guy next to him and opened it for Lin Feng to read the record.

"Well, it's good, Brother Sun is very attentive." Lin Feng simply flipped through a few pages, and found that he did remember it very seriously, and explained to Sun Cuo in a low voice, "This time and record are trade secrets, don't let others easily see this book." ”

Sun Cuo kept nodding.

Suddenly, Lin Feng found that a guy was covered in sweat and was desperately squeezing the bellows to blow air towards the steelmaking furnace, and Lin Feng suddenly stopped.

How could you forget the piston bellows? Lin Feng patted his head, asked Sun Cuo for a pen, and drew on the paper.

He painted the bellows that he used to burn fires in his rural hometown when he was a child in his previous life, which is the famous piston bellows in history, which is the most important invention in China in terms of blower technology. The piston bellows first appeared in the "Xiangshu of the Third World of Yan Bird Dou Shu" printed in 1280 AD, and its shape and structure are not much different from the style contained in the Ming Dynasty's "Tiangong Kaiwu". The piston bellows exhausts the air at one end in each stroke, and sucks the same amount of air at the same time at the other end, which is equivalent to the positive and reverse strokes are doing useful work, so it can provide continuous air flow and improve the efficiency of air blasting, which is a major progress in blower technology.

Ever since Lin Feng started painting, Sun Cuo has been staring intently at his really unsightly "works". After Lin Feng finished painting the appearance, he began to paint the internal structure of the bellows. Once, the bellows in his house was broken, and he invited a capable person in the village to repair it, and he was curious to watch the whole process intently and get familiar with the entire internal structure.

"Brother Lin, this thing is used to blow the wind, right?" Sun Cuo couldn't hold back and asked first.

"Exactly. You see, the whole box is sealed, only one hole in the front and back and one air outlet on the right side are left, and a strong sealed separator is made in the middle, which can be strung with chicken feathers on the edge to ensure that there is no air leakage. In this way, the air will continue to blow out when pulling back and forth. Lin Feng explained.

"Wouldn't that be a pull on the top blow bag and squeeze it twice?" Sun's eyes widened.

"Yes, you find a tight-mouthed and trustworthy person as soon as possible to make a batch." Lin Feng handed the rough drawing sample to Sun Cuo, walked to a steel-making furnace, and found a guy squeezing the bellows and blowing air into the furnace.

Alas, it would have been nice if pure oxygen had been concocted earlier, and the steel would have been more refined in this way. Lin Feng sighed secretly in his heart, turned his head to Sun Cuo and said, "Brother Sun, you continue to follow the test method, after refining steel of different hardness, make a few weapons respectively, compare them with each other, and take out the sharpest treasure knife as soon as possible, I have an urgent need." ”

"Okay." Sun Cuo was much more excited than Lin Feng, looking at the steaming blast furnaces in front of him like his own child.

"In the future, Li Chun will come here to help when he is not training, and the other children will decide whether they can come here according to their personal time. During this period of time, you should secretly find more loyal and reliable people to help. Believe me, the sooner you come up with the most powerful weapon in the world, the sooner I will provide you with the opportunity to make a name for yourself, and the sooner our business will grow by leaps and bounds. Lin Feng told Sun Cuo again.

Sun Cuo looked at Lin Feng in front of him like little stars in his eyes, and only nodded violently.

After saying goodbye to Sun Cuo, Lin Feng found that there was a leak to show that it was already a child at this time. At the moment, the street is basically unoccupied. The patrol sergeants who occasionally passed by saw the eye-catching Zheng Wangfu sign on the carriage, and immediately waved their hands to let them go.

Another knife. Lin Feng couldn't help but smile when he thought of the knife that Sun Cuo was about to create. In front of his head, a fruit knife made him acquainted with Sun Cuo, and he also earned the start-up capital to fool Li Yu, which can be regarded as a crack in the stubborn feudal society behemoth of the Southern Tang Dynasty that is about to be harmonious in the north; Now, the knife invented by himself and Sun Cuo will hit this monster hard again, completely smashing something.

With a relaxed heart, Lin Feng couldn't help humming the tune of the saxophone "Coming Home". Go home, go home, someone cares that the place is home, thinking of Yaya and Chen Fei, the smile on the corner of Lin Feng's mouth became stronger.

Suddenly, Lin Feng thought of the eyes at the investment conference, those eyes that were clear and calm. His heart suddenly beat wildly, and the smile on his face froze.

At that moment of encounter, you have a beautiful face and beautiful eyes; You are quiet and leisurely, tender and graceful; It is like a glorious autumn chrysanthemum, and a spring pine in Huamao; It is like an epiphany in the morning dew, and the end of the world is close in an instant.

Emperor Zhou E, could it be that I have spanned more than a thousand years, and I am here for you in the dark? After such a thought came to Lin Feng's mind, he could no longer erase it.

Lin Feng suddenly sat up straight and told Li Qiang to hurry home. Although Li Qiang was surprised by this order, which was contrary to Lin Feng's command to slow down when he got into the car just now, he still immediately whipped his horse and urged the horse to move quickly.

Lin Feng told Li Qiang to wait, rushed into the courtyard and ran into the house, not bothering to say hello to the maid who was still waiting for him in the candlelight, and rushed directly to the table to get a pen. Because he was in too much of a hurry, his left foot "slammed" against the table leg, and the sharp pain suddenly made him grin.

Yaya wanted to laugh but didn't dare to laugh, so hurry up and come over to polish Lin Feng's ink.

Lin Feng brushed and drew on the paper for a while before putting down the pen and carefully holding the two pieces of paper in his hands. Lin Feng raised his head and saw the girl who was a little puzzled in front of him, and he couldn't help laughing, the chick who had never been in love just didn't have the strength.

Lin Feng touched Yaya's head, shook his head, drove out of the house with a smile, handed over the two pieces of paper to Li Qiang, and instructed him to send them to Zhou's mansion early tomorrow no matter what, and be sure to hand them over to Zhou Jing himself.

That night, although Lin Feng was so tired that his whole body was sore, and he couldn't open his eyes, he had insomnia for the first time since he had traveled.
