key to come

[Shen Lang went to Mo Mei and said to sponsor her next research, she agreed, which is very reasonable]

established!

By the way, is it too expensive?

Shen Lang felt a little distressed.

By the way, the wool comes from the sheep.

"Luoxi, when will you give me yesterday's 1000 taels?"

"What 1000 taels?" Luo Xi looked at Shen Lang suspiciously.

Now she is in Shen Lang's room, where she is playing with leaves bored.

"That's right... Didn't I also calculate a trigram yesterday, and another trigram today, tomorrow, and the day after tomorrow..."

Luo Xi looked at Shen Lang with a confused face.

This is not a one-time consumption, it is charged every time.

Wait, I still have to be a prop every time I do a fortune-telling, why is it like I have to give him money if he prostitutes me?

"This is the Yinyang family's money, not yours." Seeing that she was puzzled, Shen Lang quickly explained.

"That's it." Luo Xi suddenly realized that she didn't have to pay for it.

"Well, people will apply, and Dongjun probably won't care."

[Mo Mei agrees to go on a long journey with Shen Lang, since Mo Mei is a master, Liang Zan can rest assured, this is very reasonable]

[Liang Zan went to report to the emperor, the emperor saw that Mo Mei was walking with Li Yunchen, it was because of Li Yunchen's business, and he didn't stop him]

established!

Dongjun, here I come.

"Ho ho ho ho..."

Shen Lang laughed strangely.

"Little brother, what are you laughing at?" Luo Xi looked at Shen Lang suspiciously.

"It's nothing, I'm going to retreat for a few days, so be good yourself."

This matter really can't bring Luo Xi, Luo Xi can't leave Chang'an, and can't even know, otherwise, if he and Luo Xi disappear at the same time, it will easily arouse Dongjun's vigilance.

"Retreat?" Luo Xi's heart tightened: "No, I have to send information to Dong Jun every day, otherwise..."

"Otherwise, what's the matter?" Shen Lang looked at her suspiciously.

"There is a curse in the house, if you don't give it away, it will be destroyed!" Luo Xi said anxiously.

The last time Shen Lang didn't take advantage of others' danger, Luo Xi trusted Shen Lang a little more, so she directly talked about this kind of thing.

"It's okay, just send it once a day, and say that if there is no change, it will be over? Can you save you a few times of grievances." Shen Lang felt that it was time to nourish his kidneys: "The things I calculated are absolutely accurate, and there will be no changes. That Dongjun is unnecessary."

"But... people are still worried, what if something goes wrong." Luo Xi said hastily.

"Then you will enter the Qin Tianjian with me. When the time comes, I will retreat on the top floor. I will count it for you once a day and find someone to send it to you. If you are on the top floor of the Qin Tianjian, with the help of a master, you don't need to enter the sage mode." It can also be calculated." Shen Lang said: "This retreat is because the master sees that my progress is too slow and I can't pass it. I don't say what I am, Dong Jun has already left, he is helping me in my practice, even if he guessed it. I will also turn a blind eye."

"Can……"

"That's the only way to go." Shen Lang spread his hands and said, "My retreat is the master's order to die, and I can't help it!"

"Huh..." Luo Xi struggled.

At this time, I can only hope that my little brother will not make a mistake, otherwise if Dongjun finds him...

She couldn't help shivering.

Looking at Luo Xi's appearance, Shen Lang felt distressed.

He walked up to Luo Xi and hugged her from behind.

Don't worry, I promise to let you down and get rid of this psychological shadow.

"My divination skills are unparalleled in the world. Regardless of the short time I have learned, it is reasonable for the master to accept me as a disciple. Last time, Dong Jun convinced me."

"Little brother... When you comfort someone, can you put your hands outside their clothes and hold their belly... Well, don't rub it!"

Chapter 152 Bicycles

Shen Lang came out of the inn and went directly to the Mo Family's Che Yunfang, and chatted with the Seventh Elder alone.

Shen Lang said that he would take Mo Mei out and let her work for pay, and the Seventh Elder readily agreed.

"However, it still depends on what the child thinks." The Seventh Elder stroked his beard with some emotion.

It's not easy to get Mo Mei to leave the laboratory, even if it's to make money. Unless she is really short of money, she won't let go of her research.

Unexpectedly, for a student like Li Yunchen himself, he would go to Youzhou to find opportunities, and he would have to pay a lot of money to hire a master like Mo Mei.

Mo Mei seems to be in the same class as Li Yunchen and Luo Xi, but Mo Mei is actually ten years older than Luo Xi, so it is not an exaggeration to count her as Ji Wangshu's generation, but her generation is just the same as theirs.

In other words, if it was for Luo Xi, would Shen Lang still do this?Probably not.

Sure enough, Luo Xi was just an accident, and Li Yunchen was the true love.

"Don't worry, as long as she comes here, I will have a way to persuade her."

"Well, I sent a message to the organ city." The seventh elder said: "As long as she is not doing particularly delicate things, she will come soon."

"Okay." Shen Lang nodded.

"Let's pass the time, what do you think of the current traffic?" Seventh Elder said to Shen Lang.

He finally came to Che Yunfang, so he had to improve his interest in machinery.

"Traffic? Now the streets are full of horse-drawn carriages, and some people even ride horses in the outer city. I think the traffic arrangement is not good." Shen Lang said instinctively: "Would it be better to divide it into carriageways and sidewalks?"

"Hahaha, good idea, but you are still young." The Seventh Elder smiled and said, "How many carriages are there in the city, and how many people are qualified to ride horses in the outer city? If there are such a small number of people to create a roadway, the loss outweighs the gain."

"That's a problem with the means of transportation. Wouldn't it be good to make something that ordinary people can afford?" Shen Lang said casually, "For example, a bicycle."

"Bicycle?" The Seventh Elder was stunned for a moment, and casually took out a piece of paper for Shen Lang: "Tell me carefully."

Shen Lang looked at the white paper and started drawing casually.

The bicycle is too close to him, and he often rides a shared bicycle. Although his drawing skills are not very good, he can still tell the general appearance.

"Look, this wheel is the same as the wheel of a carriage, the difference is that instead of using a horse, it relies on the strength of human feet..." Shen Lang frowned slightly, can tires be produced in this era?

"The outside is wrapped with animal skin to prevent bumps. Then step on it and use it to drive, and the car can move."

Fortunately, it was the Seventh Elder who was chatting with Shen Lang, and Wang Mang had already proposed the concept of train wheels, otherwise, I really didn't understand what Shen Lang was talking about.

This is where Shen Lang is more troubled. He knows a little about everything, but he is not good at everything.

"Here, how do you master the balance?" The Seventh Elder wondered, "Can ordinary people master it?"

"Yes, you can make one, and I'll let you ride it to see." Shen Lang spread his hands and said: "Unfortunately, this thing cannot be mass-produced."

"Mass production is fine. It needs to be produced on an assembly line. Don't underestimate the machinery of the Mo family." The seventh elder stroked his beard.

Shen Lang looked surprised, this Mo family can do it, they all know the concept of assembly line?

In other words, is there any automated machinery in this era?What kind of drive is used, and there is no electricity at this time.

"Tell me carefully, the details of each part."

"This is just a temporary idea of ​​mine. I don't know the details. I still have to rely on the teacher to complete it. If this thing is used for traveling, it will save time." Shen Lang was a little embarrassed.

Where would he know the details of those parts?I can remember a general shape, okay?

"Well, this chain is used to control the rear wheel. It buckles the teeth of the outer gear of the rear wheel. When the pedal is stepped on, the curtain and the gear rotate to drive the rear wheel. In theory, this is the case. How can this chain be designed to buckle The teeth are convenient, I don’t know about that.”

"It turns out that the one you drew is a chain and gears... what is this for?"

Shen Lang doesn't know how to explain the principle of these things, but this is not difficult for the Mo family, the seventh elder can see the function of the chain at a glance.

"This is the handle, which is used to control the direction. Make sure that the handle and the front wheel can rotate together."

"This thing can be made of wood as a whole, but animal skin must be added?"

"If there is no leather on the outside of the wheel, I'm afraid it will be very bumpy. In my design idea, it is best to inflate the animal skin to fit the wooden wheel tightly."

"Let's figure out the shape first."

"Well, I also think, let's take it step by step. This animal skin can be sold to those who have little money, and ordinary wooden wheels can be sold to poorer people who need to travel."

"Actually, this thing is also useful in some big cities, and people will buy it. It's good to walk in small cities."

"No, teacher, you have to think this way. There were people who were very satisfied with the jobs in the south of the city, but because they were far away from home, they had to find inferior jobs in the north of the city, such as accountants. Can you go to the south of the city to find a job?"

"Also, some shops make delicious food, but people can't go there due to the distance. As long as I have this bicycle, can I go to a farther place to eat?"

"Well, it makes sense. It seems to be able to promote economic circulation. Some students rushing to take the exam have no money to rent a horse. If the cost of this bicycle is not high, it will be much more convenient for them to come to the capital to take the exam."

The Seventh Elder and Shen Lang began to perfect the design.

Shen Lang has already provided the general direction and specific shape. The Seventh Elder has rich experience, and he does it while talking.

Shen Lang was surprised to find that the bicycle was made by him in less than two hours!

Shen Lang fell into inertial thinking just now, and he forgot that this is not a normal ancient time. The Seventh Elder made wheels, gears, and chains with his bare hands, which made his jaw drop in shock.

"The problem is the chain instead. You have to make small ones and fasten them with wooden strips to achieve the effect you want. Fortunately, this is not a problem for me." The Seventh Elder casually buckled up the chain .

This is the most coquettish, he created the effect of mechanical production with bare hands.

Now the two of them are in the backyard of the Seventh Elder alone in Cheyunfang, neither big nor small.

"Come on, didn't you say you can master the balance? Try." The Seventh Elder pointed to the bicycle.

"Well, there is still a parking and brake missing, but it's not a big problem."

Shen Lang got on the bicycle, took a deep breath, and drove the bicycle around the yard.

Grass, no tires are still a bit bumpy, and it's hard to ride.

Because it is the first time to do it, some connections are not perfect, but it is only a matter of time before it is perfected.

"You can really master the balance, and you are an ordinary person who has almost no cultivation..." The seventh elder looked surprised.

Shen Lang suddenly had black lines all over his head, Lord Lang, I am also a ninth-rank master, okay!

Chapter 153 Jealous

"By the way, I have a patent fee for this, right?"

"patent?"

"It's the dividend after the sale."

"Naturally." The Seventh Elder couldn't help but sigh with emotion.

Talent is such a thing, it's really hard to say clearly.

Shen Lang just walked around here and solved an obvious traffic problem. It seems that the last Hongmen Banquet and the unraveling of Shangtong Mo Fang were not accidental.

Would it be impossible for other Mohists to make this bicycle?It's just that no one can think of it.

I have seen high-level Mohist designs, and they think about difficult things, such as machines that can fly in the air for several days and carry hundreds of people, and vehicles that can carry thousands of people at a time. use.

The Seventh Elder feels that the things made by the Mo family are too much for military use, and the inventions have always been mainly for military and personal use. They are all aimed at high-end, and only some gadgets will be lost to the people.

Perhaps, we should let everyone think about people's livelihood and invent what can benefit the country and the people, instead of inventing those difficult mechanisms all the time.

"It's good if you have money." Shen Lang couldn't help smiling when he saw the wool growing out of the sheep again.

"By the way, remember to add the brake function to this. You can't keep the foot brake. The principle is that there is a mechanism here on the handle. When you press it, the connection of the mechanism will rub against the side of the wheel, so that you can brake. Also, parking You have to design it too."

"Okay." The seventh elder nodded: "You are indeed the lucky star of my Mo family."

Shen Lang got off the bicycle and parked the car skillfully to the side: "By the way, you can also get a tricycle, or a cart pulled by people, the principle is this..."

Soon, Shen Lang drew the general style of tricycles and rickshaws of later generations.

Given the opportunity to share the money, he can be said to go all out.

Bicycles have come out, and the principle of tricycles is similar, and rickshaws are simpler.

The Seventh Elder listened carefully and felt that Shen Lang's invention would solve the problem of wasting manpower in some cities.
