In fact, in Lin Feng's original idea, he didn't care too much about the fifth and seventh questions of recruitment. To put it bluntly, Lin Feng's original intention in coming up with these two questions was to inspire and inspire the people of the Southern Tang Dynasty, telling everyone that efficient farm tools and power facilities can also be a big field of innovation and invention, and the vast world in it can make great achievements.

Without him, before the invention of the steam engine, China for thousands of years, no, even within the scope of the world, agricultural planting methods and farm tools, as well as labor-saving and efficient power facilities have not made much progress, the reason is very simple, on the one hand, the steel casting technology has affected the precision and quality of steel, on the other hand, the utilization rate of power in nature has always been low. Without the invention and breakthrough of the theory of energy conservation, the utilization of water, wind and heat in nature will always be only a subsidiary and foil, and only human and animal power can be relied on at present.

Lin Feng walked over with a smile and watched carefully. Inside the box is a handmade wooden instrument topped by a funnel-shaped object with three strings leading out of the front, two handlebar-like handlebars at the back, and three long, curved passages below. Because of its small proportions, it looks like a child's toy.

Lin Feng couldn't help blurting out: "Improved car? ”

The cocoon car is also called the cocoon plow, the cocoon, it is the earliest animal power seed drill created and invented by Zhao Guo of the Western Han Dynasty in the 2nd century B.C., which is composed of cocoon frame, cocoon bucket, cocoon leg, cocoon shovel, etc., there is a leg of cocoon to seven legs of cocoon, which can sow barley, wheat, soybean, sorghum and other granular crops.

The cocoon car is also a great invention in ancient Chinese agricultural planting, to know the Tao, the West did not invent the seed drill until the 16th century AD, but it has been on demand by hand! In terms of numbers, China's sowing system is at least 10th in efficiency in Europe, and 30th in Europe in terms of harvest. This type of seeder has a long history of use, and even in the 21st century, it is widely used in areas where mechanized equipment is not widely used.

Deng Jiayu's eyes widened suddenly, and he looked at Lin Feng in great surprise, he never thought that Lin Feng could see the improvement of his invention at a glance. Previously, Hu Cheng had also introduced Deng Jiayu to Lin Feng, but the two basically did not talk to each other. The reason is very simple, in Hu Cheng's private words, Deng Jiayu's temper is stinky and hard, he is too arrogant, and he doesn't take his boss seriously at all, so he can only be a ninth-rate petty official.

"Are you trying to solve the motivation problem?" Lin Feng asked.

Deng Jiayu's look of admiration became more obvious, and he nodded vigorously. In this era, animal power is also very valuable, otherwise, the carriage would not have become a luxury. Deng Jiayu's idea was to make the cart lighter and more labor-saving, so as to replace animal power with a small amount of manpower.

Lin Feng picked up the drawing, which was a schematic diagram of a blower, which was roughly an idea of combining the ancient bellows and bellows. Lin Feng couldn't help laughing, Old Deng, you made it too complicated!

Lin Feng said to Deng Jiayu, "Please explain your invention to all the adults." After speaking, Lin Feng walked to the bookcase and used a brush to draw the piston bellows that he had drawn for Sun Cuo.

A group of examiners watched dumbfounded as Deng Jiayu splattered and introduced the improvements of his invention, only Li Deming, a waiter of the Ministry of Industry and an academician of arts and sciences, looked at Deng Jiayu with bright eyes, and looked down at the "ugly toy" in the eyes of others from time to time.

After Deng Jiayu finished speaking, Lin Feng stepped forward and handed his very ugly painting to Deng Jiayu, Deng Jiayu took a cursory look, immediately widened his eyes, looked up in surprise and asked, "Lord Lin, this is what you created?" ”

At this time, Lin Feng didn't mind taking the invention of the piston bellows as his own, and said with a smile: "Yes, the real thing has been made and it has begun to be used in steelmaking." ”

"Lord Lin, can you allow the villain to take a look?" Deng Jiayu grabbed Lin Feng's sleeve. A person who is engaged in invention and creation, and suddenly finds himself thinking hard about the proud work of meditation, others have already invented it, and it is simpler and more convenient than his own, and the impact is absolutely shocking.

"I'll take you around for a chance." Lin Feng smiled mysteriously. For such a person with ideas and operational ability, Lin Feng also intends to completely subdue him and give full play to his role.

"Lord Xie Lu Xie Lin, Lord Xie Lu Xie Lin." Deng Jiayu rubbed his hands excitedly, turned around twice in place, suddenly remembered something, reached out and took out a stack of papers from his arms, handed it to Lin Feng, and said excitedly, "Please read it, Lord Lin." ”

Lin Feng took it and flipped through it carefully, and couldn't help but sigh in his heart, talent. In this stack of paper, there is an improved version of the textile wheel, and there is an improved version of the leakage, although many places look very simple and unreasonable in Lin Feng, but this kind of awareness of innovation and breakthrough is too rare!

However, Lin Feng knew that the current occasion was not suitable for a detailed discussion, handed the paper back to Lao Deng, and said with a smile: "Let's talk about these later." Let's hear what the adults have to say. ”

"That's right! Right! Deng Jiayu's body turned halfway, but his eyes kept staring at Lin Feng. He had seen Lin Feng three times, and for the first time he felt that Lin Feng was so close to him.

The adults almost watched Lin Feng and Deng Jiayu make this scene of the episode, for the invention of agricultural machinery, except for Li Deming, who didn't understand anything half, they all knew seven tricks and six tricks, and only one thing left.

Zhou Zong saw that everyone didn't have anything to say, so he nodded at Lin Feng.

Lin Feng understood, and guided Deng Jiayu to the table next to him and left his name, address, official position, etc.

Before dusk, the examiners interviewed the sixth question of textile and cotton machinery and the seventh question of high-efficiency power facilities in a row, basically watching Lin Feng sing a one-man show alone, Lin Feng respectfully asked for advice with the attitude of a student, and Lin Feng sent people away and scared away in a few words.

Later, the examiners also really recognized Lin Feng, a "demon" who seemed to know everything, and simply handed over the power of presiding over the inspection to Lin Feng, and was happy to watch the excitement on the sidelines.

Seeing that it was not early, Situ Zhouzong stood up and said with a smile: "Everyone, you have worked hard! It's going fast today, so it looks like we're going to have the interview over in a few days! ”

The examiners also showed a relieved look and got up to go home.

Situ Zhouzong spoke again: "In order to thank you for your great support, the old man has prepared a table of thin banquet in the house tonight, please go with your face."

As the richest man in the Southern Tang Dynasty, Lord Situ used to often entertain guests, but since Shangshu's right servant Sun Sheng made a luxurious family banquet and successfully led the luxury banquet in Jinling City, Lord Situ rarely invited guests.

This is a great opportunity! A group of people responded happily, and their faces bloomed with smiles. As for Lin Feng, he still wanted to take the opportunity to meet Emperor Zhou E again, so he was naturally more anxious than the others.
