Li Lizhi widened her speech and looked at Du He happily: "Really? Let's build mahjong for sale? ”

Du He nodded: "That's right, you can't make money by selling mahjong alone, it's best to match the mahjong table, then you can make more." ”

"Wow, Duhe, you're so nice!" Li Lizhi said happily, stood on tiptoe, and chirped with Du He.

Then, the little girl ran away with a red face.

……

Just do it, don't do it is a soft egg.

After dinner that day, Duhe locked himself in his room and began to design the drawings.

First of all, it is not difficult to add a mahjong production line in the furniture factory.

Anyway, it is to cut the wood into pieces first, and then polish, and then carve after polishing, since the invention of mahjong in Duhe, the furniture factory has produced dozens of mahjong one after another, and it can be said that it is familiar with the road.

The only trouble lies in the production of mahjong tables.

Of course, a simple table is not difficult, and it only needs to be transformed with an ordinary table, but what Duhe wants to do is a semi-automatic mahjong table, which can also become a mahjong machine.

His initial idea is to shuffle the cards in a hand-cranked way, even if the efficiency is slow, it doesn't matter, as long as it can be realized, in this era, it is definitely a high-tech existence, and I am afraid that someone will buy it for 10,000 yuan, which is what really makes money, and it is also the content that can really form barriers.

Naturally, the design is also quite difficult.

As a liberal arts student in later generations, Du He only knew a little about machinery, and many things were actually explored by himself.

For example, the most important automatic shuffle part of the mahjong table structure, Du He intends to learn from the design ideas of later generations, the use of magnet principle to achieve, put a magnet on the back of the mahjong card, and then design a turntable with a magnet under the mahjong table, after shaking the hand, you can suck the back of the mahjong, with the rotation of the turntable, the mahjong will be sent to the groove next to it, placed neatly, and then sent to the desktop.

It's a brain-wrenching technical task.

Du He spent a whole night and finally designed the drawings, and the next morning he didn't even have the heart to sleep, so he took Zhang Du and two craftsmen to do it.

Du He took the three of them to hide in the laboratory, which was an operation. I just heard the tinkling in the laboratory, and no one knew what was going on inside.

……

Three days passed, and Du He finally made the first semi-automatic mahjong machine in Datang.

In the past few days, he has not eaten or drunk, and has carried out experiments again and again, although the principle is simple, but the accuracy of the manufacturing industry is not accurate, resulting in problems again and again.

Even this mahjong machine is rough, far from Duhe's expectations, and the probability of successful hand-cranked shuffling is only 60%.

That is, about four times out of ten it will get stuck.

Once stuck, open the lid underneath and press a button to pour out all the cards and put them back in.

And the good mahjong is not from the four mouths, the second is from a mouth out of four, you need to get it to the four sides of the table by hand.

Even with its many flaws, in this era, this is still a cross-era high-tech device.

Zhang Du and others couldn't even believe that this was the machine they were personally involved in building.

Zhang Du said proudly: "Young master, if this mahjong machine is sold, I'm afraid it can be sold for 10,000 yuan." ”

Du He rubbed his messy hair and exhaled: "Sell a few, this thing is always stuck, buy it back as an ornament, a machine that is not easy to use, then there is no need to exist." ”

As he spoke, Duhe picked up the hammer and smashed the machine with a crackle.

Zhang Du and the others didn't even have time to stop it.

Looking at the parts scattered all over the place, everyone was a little dumbfounded.

Zhang Du looked at Du He in surprise: "Young master, this ......"

"It's okay, Young Master Ben went to sleep, and then I said later, it's not a problem of workmanship, it's caused by a defective design, and I'll start over again after Young Master Ben has revised and perfected it...... Semi-finished products can't be pushed to the market, and when the time comes, it's the young master's signboard! ”

Du He waved his hand, and when he returned to his room, he fell asleep.

This night, Du He slept for a day and a night.

Halfway through, Li Yuanshu and Li Lizhen both came to visit, but they were directly stopped outside by Lu Bu.

On the second day, after Du He got up, he felt refreshed, picked up the banknote, and was ready to continue designing the mahjong machine.

At this time, Lu Bu's voice sounded outside: "Young Master, someone is visiting!" ”

"Who, no!" Du He waved his hand and said.

Lu Bu said at the door: "Young master, it's your concubine." ”

Du He was stunned.

Then he jumped up quickly, ran to the door, and slapped Lu Bu on the back of the head: "Bastard, you, this young master is high-spirited and bright, guarding himself like a jade, where did you ......come from?"

Lu Bu said with a confused expression: "It's the woman who invited you to work in the small courtyard that day in Deyue Tower." ”

As he spoke, Lu Bu showed a hehe smile and stared at Du He.

Du He's face sank: "Lu Bu, you've been a little skinny lately!" ”

Lu Bu: "Hey, hey, hey...... It's all taught well by the young master. ”

Du He secretly wondered in his heart, Mo Yifei suddenly came to visit, could it be that there was something good?

If you want to talk about the two, I have only met them twice, and they are both extremely embarrassed.

With doubts, Du He came to the living room and met Mo Yifei.

Mo Yifei seems to be more beautiful than before, and only brings the maid Xiaoping with her.

"Du Gongzi, long time no see!" Mo Yifei saw Du He and took the initiative to bow down.

Du He scratched his head: "Didn't you see you in Deyue Tower last time, and it's not been a few days......"

Murphy: "......"

The two sat down and exchanged pleasantries.

Mo Yifei realized that Du He had been perfunctory to himself, talking with a match, and his heart was not in the horse.

After a pause, Mo Yifei said straight to the point: "Du Gongzi, I think you are worried about the mahjong machine, right?" ”

Well?

Du He raised his head and stared at Mo Yifei carefully, with murderous intent in his eyes.

"Oh, Du Gongzi, you scared the little girl, you were so fierce just now, your eyes looked like you were going to kill, the little girl was so scared ......" Mo Yifei said coquettishly.

Du He didn't eat this, and said coldly: "I don't like to go around the bend, let's say, how did you know about this?" ”

Mo Yifei covered his mouth and smiled: "It's not a secret, now, many people know that you make a mahjong machine, because you didn't succeed in smashing it to pieces, the little woman came to the door today, just to solve the problem for Du Gongzi." ”

"You are a weak woman, how can you help Young Master Ben solve the problem?" Du He asked with a smile.

Mo Yifei snorted lightly: "Du Gongzi, don't underestimate the woman, you also went to Deyue Tower to see my small courtyard that day, what do you think of the design of the donkey to draw water?" ”

"Quite ingenious!"

"Du Gongzi, have you ever heard of the Mo family's tricks?" Mo Yifei suddenly asked.
