Lin Feng looked relaxed when he saw the guy coming up, and he speculated in his heart that it might be Sun Cuo's breakthrough in researching coke and steelmaking. Lin Feng pulled Chen Fei and asked him to run to Zheng Wang Mansion and asked Li Qiang to come over again.

As expected, the guy kept running two steps and bowed: "Mr. Lin, Master Sun's family asked you to come over and say there was good news."

"Haha, thank you guys. Let's go now." Lin Feng hurriedly hugged Yaya and asked the brother and sister to have dinner on their own. He didn't care about his fatigue and rushed to the Zheng Wang Mansion with the fellow named Zhang Yongde. As soon as he crossed the street corner, he happened to meet Li Qiang driving.

After getting on the bus quickly, Lin Feng ordered to go to Sun Ji iron shop, he fell asleep. After that day, he was so tired.

"Brother Lin, wake up." Lin Feng was shaken in confusion. 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 burnt, forming a pit. Although his expression seemed to be in a difficult position, he smiled and looked very energetic.

"Oh, Brother Sun, don't work too hard." Lin Feng pointed to the burnt area on Sun Cuo's hair, "Has he been baked once?"

"I'm not a duck, you've just been roasted! Come down quickly, I'll show you something good." Sun Cuo smiled and scolded, dragging Lin Feng out of the car.

Lin Feng followed Sun Cuo into the shop and found that it had completely changed its appearance, varying in height, and the yard was filled with stoves of different sizes. The whole place was like an African grassland full of termite nests.

Sun Cuo ran into the room on the north side and picked up two dark things like holding a treasure.

Coke appeared more than 300 years ago? Lin Feng repeatedly weighed the two pieces of coke in his hand under the dim candlelight. It was lighter than coal, and his body was filled with small pores, reflecting a cold light under the candlelight.

"This coke is obviously resistant to burning than coal, and it doesn't taste much. I tested seventeen furnaces in a row and found that the coke in that furnace is the best. Now they have been put into seven steelmaking furnaces and are constantly practicing." Sun Cuo said excitedly.

"Did you remember the firing time of that furnace, the size of the firepower and the capacity of the furnace?" Lin Feng asked quickly.

"I've recorded it. I've kept it in detail." Sun Cuo took a account book from a fellow reporter next to him and opened it for Lin Feng to see the records.

"Well, it's great, Brother Sun is very attentive." Lin Feng simply turned a few pages and found that he remembered it very seriously. He whispered to Sun Cuo, "This time and record are commercial secrets. Don't let others see this book easily."

Sun Cuo kept nodding.

Suddenly, Lin Feng found a friend covered in sweat, squeezing the wind bag desperately to blow the wind into the steel furnace, and Lin Feng stopped immediately.

How could he forget the piston bellows? Lin Feng slapped his head, asked Sun Cuo for a pen, and started drawing it on the paper.

He painted a bellows that he often used when he was burning fire in his hometown in his hometown in his childhood in his previous life. It was the most important invention of China in terms of blowing technology. The piston bellows first appeared in the book "The Book of the Three Worlds of Birds" printed in 1280 AD. Its shape and structure are not much different from the styles contained in the "Tiangong Kaiwu" of the Ming Dynasty. In each stroke of the piston bellows, one end of the piston bellows exhausted and the other end absorbed equal amounts of air at the same time, which is equivalent to working hard both on the front and reverse strokes, so it can provide continuous wind flow and improve blowing efficiency, which is a major improvement in blowing technology.

Since Lin Feng started painting, Sun Cuo stared at his really unsightly "work". After Lin Feng finished painting the appearance, he began to draw the internal structure of the bellows. Once, the bellows at his home broke and invited people from the village to repair them. He was curious and watched the whole process in absent manner and became familiar with the entire internal structure.

"Brother Lin, is this thing used for blowing the air?" Sun Cuo couldn't help but ask first.

"That's right. Look, the entire box is sealed, leaving only a hole in the front and back and an air outlet on the right. A solid and sealed paper is made in the middle, so that chicken feathers can be tied on the edge to ensure that there is no air leakage. In this way, wind will be continuously bulging when pulling back and forth." Lin Feng explained.

"Wouldn't that be the blow-on bag once and squeeze it twice?" Sun Cuo widened his eyes.

"Yes, you can find someone who is trustworthy as soon as possible to make a batch." Lin Feng handed the rough drawing to Sun Cuo, walked to a steelmaking furnace, and found a friend squeezing the wind bag and blowing air into the furnace.

Alas, it would be great if pure oxygen could be produced earlier, and the steel refined in this way would definitely be more refined. Lin Feng sighed in his heart and turned to Sun Chou and said, "Brother Sun, continue to use the test method to make steel of different hardnesses, and make several weapons respectively, compare them more with each other, and take out the sharpest sword as soon as possible. I have urgent use."

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

"In the future, Li Chun will come here to help when he is not training, and other children will decide whether they can come here based on their personal time. During this period, you must secretly find more loyal and reliable people to help. Believe me, the sooner you take out the most powerful weapons in the world, the sooner I will provide you with the opportunity to become famous all over the world, and the sooner our business will make rapid progress." Lin Feng once again told Sun Chou.

Sun Cuo looked at Lin Feng in front of him with little stars, leaving only nodding suddenly.

After saying goodbye to Sun Chou, Lin Feng realized that even more noises were missing, which showed that it was midnight. At this moment, there was basically no one walking around on the street. Occasionally, the patrol soldiers who passed by saw the eye-catching Zheng Wang Mansion signs on the carriage, all immediately waved their hands and let go.

Another knife. Lin Feng couldn't help but laugh when he thought of the knife that Sun Cuo was about to build. In front of his head, a fruit knife made him meet Sun Cuo and earned the start-up capital to fool Li Yu. It was considered to be a crack in the stubborn and stubborn feudal society that was about to be pried open by the northern harmonious feudal society. Now, the knife he and Sun Cuo jointly invented will once again hit the monster hard and completely cut off some things.

With a relaxed heart, Lin Feng couldn't help but hum the tune of Saxophone "Go Home". When he went home, someone cared about the place where he was home. Thinking of Yaya and Chen Fei, Lin Feng's smile became stronger.

Suddenly, Lin Feng thought of the eyes at the investment promotion conference, those eyes that were bright and clear, as quiet as the sea. His heart suddenly hopped wildly, and the smile on his face also solidified.

At that moment of meeting, you have a beautiful face and a smooth eyes; you are quiet and leisurely, tender and graceful; like a glorious autumn chrysanthemum and lush spring pine; or like a flash of cereal in the morning, and you are in a flash of time.

Zhou Ehuang, did I come for you in the dark for more than a thousand years? After this thought came to Lin Feng’s heart, it would never be erased.

Lin Feng suddenly sat upright and told Li Qiang to rush home quickly. Although Li Qiang was surprised by the order that was contrary to the order that Lin Feng ordered to slowly take when he got on the car just now, he immediately waved his whip and urged the horse to go quickly.

Lin Feng told Li Qiang to wait, and rushed into the yard and ran into the house. He didn't bother to say hello to Yaya who was still waiting for him in the candlelight, and rushed to the table to get a pen. Because he was too anxious, his left foot hit the table leg with a "bang" and the severe pain immediately made him grin.

Yaya wanted to laugh but didn't dare to laugh, so she came over and polished the ink for Lin Feng.

Lin Feng wrote and drew on the paper for a while before putting down the pen and carefully holding the two pieces of paper in his hand. Lin Feng raised his head and saw Yaya who was confused in front of him. He couldn't help laughing. The young birds who had never fallen in love were just lacking in concentration.

Lin Feng touched Yaya's head, shook her head, and rushed out with a smile, handed the two pieces of paper to Li Qiang, and told him to deliver it to Zhou's mansion early tomorrow morning no matter what, and he must hand it over to Zhou Jing in person.
