"I can't step on it!" Qian Zhongshu in the rice cutter poked out his head and stuck out his tongue, tired like a pug, panting, and didn't stop for a long time.

The other two senior brothers, Ma Yu and Dian Le, were no better, and they all looked like they were in prostration. Shouting that he had no strength.

Li Zhuo looked at Chen Fei with interest, and Chen Fei's face was pale at the moment, and his face was solemn.

"Know what's wrong?"

Chen Fei was silent for a long time, and finally nodded heavily, with a hint of helplessness on his face.

"The whole rice cutter is too heavy, just rely on three people to step on it manually, and it is very difficult to run the rice cutter on flat ground, if you work in the field, I am afraid that the rice has not been cut, and people will be tired to death." Chen Fei reluctantly told the truth.

Chen Fei felt that the speed was very slow when the rice cutter was on the flat ground just now, but he didn't think much about it, and it wasn't until the rice cutter entered the weedy lawn that Chen Fei discovered the seriousness of the problem.

As mentioned before, the front roller cutter of the rice cutter is linked to the tires of the rice cutter, and the tires move, it also moves, and the people who urge both are the people who step on the pedals on the car.

The weight of the rice cutter itself requires three people to step on it at the same time, and after entering the weed area, it is necessary to overcome a lot of resistance to cut off the weeds, which is completely impossible to do with the strength of three people.

Well, to put it simply, it's a problem caused by "lack of power".

This is a difficult problem, the most primitive steam engine was born more than a thousand years ago, and Chen Fei is not a mechanical major, where to solve this problem?

Redeem the raffle ticket for the [Internet Search Ticket] and [Memory Potion] and then search the Internet?

Chen Fei quickly dispelled this idea for two reasons.

First of all, with the craftsmanship of this era, even if you know how to make a steam engine, most of them will not be able to build it.

Because the mechanical principles involved in it are very complex, and many precision mechanical parts need to be made, there is no such technical condition for the time being.

These mechanical parts are not replaced by wood, but must be made of iron, and the iron-smelting technology of the current era is not very developed, so it cannot be done for the time being.

Second, even if the steam engine was invented, it would not necessarily be used in the rice harvester.

Why? Didn't you see that the oldest steam trains used to run while adding coal?

You don't have to work while adding coal in the process of harvesting rice, right?

The rice harvester is not a car, and it has a lot of work load, and most of the oldest gas-powered machines can't play this.

Moreover, it is not safe, and it is also a waste of coal mine resources and causes serious air pollution.

Chen Fei is a person with a strong sense of environmental protection.

Therefore, the idea of using a steam engine to solve this problem was immediately cut off by Chen Fei, and he planned to use some other methods.

"It's a little less effort for the pinion to drive the big gear, right? And then... The use of the bearing lever principle should also have the effect of saving labor, right? ”

Chen Fei scratched his head, desperately recalling the physics knowledge he had learned before, plus some of his usual sights and hearings, and a lot of design principle information obtained from the last time he checked the system.

"Lao Li, I want pen and ink!" At this moment, Chen Fei was not polite to Li Zhuo, and directly called him Lao Li.

Li Zhuo didn't care what Chen Fei called him, in his opinion, as long as Chen Fei could do practical things, it didn't matter what he called.

Someone went and fetched pen and ink.

Chen Fei directly spread the paper on a large flat stone and concentrated on writing and drawing.

"Huh? Could this kid really be able to improve this thing? I thought he was out of luck. ”

Li Zhuo glanced at the things painted by Chen Fei a few times, and couldn't help but be dumbfounded, and soon he raised his foot, kicked the onlookers around him one by one, and kicked them away unceremoniously.

"No one is allowed to disturb him!" Li Zhuo gave an order to the onlookers, ensuring that Chen Fei could have a quiet creative environment.

Driven by Li Zhuo, Chen Fei was the only one left by Li Zhuo's side, and the rest, such as Qian Zhongshu and others, scattered to various places to help.

Li Zhuo took out a gourd of wine and poured a big sip into his mouth, a trace of drunkenness suddenly appeared in his eyes, and he drunkenly watched Chen Fei concentrate on writing and drawing, smiled secretly, and did not speak.

Chen Fei drew on the drawings for a long time, and finally completed the improved design.

"That's it!"

Chen Fei raised the drawing and shouted, attracting the attention of many people.

Because the rice harvester is the largest tool in the strange workshop, the movement of each experiment is the largest, and it is difficult not to attract attention.

In addition, under the big mouth of Qian Zhongshu and others, many people know that the owner who designed this behemoth is here, so many people are interested in Chen Fei, but no one dares to come up and make trouble when they see Li Zhuo guarding on the side.

Now that Chen Fei shouted okay, many people also put down their work and gathered around with interest.

"Yo! Isn't this the boy who designed the rice cutter? Little baby, didn't I say you, what should you do at your age, don't mess around here, do you know how much material this rice cutter wastes? We can't afford to be wasted by you, and supplies are already very tight. ”

A lean man in his thirties, with a flirtatious face, deliberately sarcastically sarcastic Chen Fei.

Many people listened to his words and agreed.

"That is, do you know that because of the waste you researched, half of the materials used to make my things have been deducted, and now I haven't even made the finished product. Still researching? Study a fart! ”

"Makes sense! Lao Tzu worked so hard to beat so much iron, and it ended up all on this waste, you say, doesn't this make my hard work in vain? ”

"That's it! It is! Boy, you'd better go home and drink milk and be spoiled! ”

"Hahaha!" The crowd burst into laughter.

Chen Fei's face was expressionless, and he turned his head to look at Li Zhuo.

When encountering this kind of thing, Li Zhuo's face was a little unbearable.

Whether it is a rice cutter or Chen Fei, it was all introduced by him, and these people say that whether it is a rice cutter or Chen Fei, it is equivalent to slapping him in the face!

"Enough! Quarrel later! Now you're all being honest with me! It's never too late to take a look at his new design before jumping to conclusions! ”

Li Zhuo rarely got angry at the craftsmen! And the anger is not small, the people who were originally sarcastic and laughing at Chen Fei suddenly put out the fire.

Don't look at Li Zhuo's usual nodding to them, but these people also understand in their hearts that Li Zhuo has contributed a lot to a strange workshop, and they still respect him from the bottom of their hearts.

Li Zhuo took the drawings and looked at them carefully, his brows furrowed more and more, and finally handed the drawings to the oldest Wang Lao.

"Elder Wang, look at this drawing, I don't understand it."
