Li Yuanjing rolled his eyes, and secretly didn't know who was stunned!

A gray bag was thrown directly into his arms, and Li Yuanjing couldn't help but be a little stunned.

"What's that?"

"Title deeds! Exactly 10,000! Cheng Chumo didn't have a good air, in order to steal these land deeds, he found countless opportunities at home to get them, but thinking about himself, the investor is really confused, and he still doesn't know what to do when the money is given!

"Ten thousand can give you up to seven thousand!" Li Yuanjing threw the bags on the ground and didn't bother to count them one by one.

"You lied to me? Doesn't that mean it's different from them? Don't you make nine out of thirteen? Co-authored only one percent less than them? Cheng Chumo was a little angry, if this is discovered by the family, lying in bed for two months is a starting price, and it turns out to be this?

"How can there be a loan and a loan? What you are given is 7,000 yuan, and the principal you will repay at that time is also 7,000 yuan, and the interest and everything are agreed, and the money bank also has to avoid risks! Li Yuanjing said directly angrily.

Cheng Chumo didn't react a little, and scratched his head: "Then I'll go home and steal some more?" ”

"That's it, less is less, it's nothing more than less shares!" Li Yuanjing shook his head and rejected Cheng Chumo's desire to invest.

is mainly for his own sake, in case this matter is discovered by Cheng Zhijie's bastard that he is instigated behind his back, Li Yuanjing estimates that the goods will hit the door nine times out of ten.

However, Li Yuanjing obviously underestimated Cheng Chumo's stubbornness and Cheng Chumo's discipline.

'Smack! ’

An identity token is slapped on the table!

"Take me to 3,000 guan, make up 10,000 guan!"

"......" Li Yuanjing looked at Cheng Chumo speechlessly for a while, why do you dare to take it, the question is what did this king do with you? I can't do, I eat and drink a lot all day, and I have an egg? It's a complete burden!

"What the hell are you going to do business? It's time to let me know something, right? Cheng Chumo doesn't care so much, people don't want it, and the money can't be earned, otherwise it will take half a year to start when you go home.

Li Yuanjing didn't know much about the excavator, and the current progress was only limited to the wooden model.

If it can be done, it will definitely be done, but I don't know how effective it will be under this kind of thinking?

If an excavator needs dozens of people to operate, the effect will naturally be greatly reduced, dozens of people digging at the same time, the speed will not be much slower.

Just when Li Yuanjing didn't know what to say, the afterglow of his eyes happened to catch a glimpse not far away.

The corners of his mouth smiled slightly, and he said, "Oh, it's coming!" ”

Yang San was full of excitement and slowly walked towards Li Yuanjing with a half-human-high wooden excavator, in fact, Yang San had been thinking about how to solve the problem during this time.

For the sake of this little thing, he even dragged Yang Li to study it every night, and let his brother help come up with a lot of ideas.

Although there are some ideas, how to operate in the end still needs to continue to verify.

Anyway, Yang San was not very satisfied with this model, but just two hours ago, Li Yuanjing had someone send a jar of black liquid.

Yang San looked at it according to the guard's explanation, and felt that the sealed filling was not enough, so he changed the instructions and directly immersed the oil into each gear.

However, after a try, he found that there was a huge surprise, so he hurriedly came to Li Yuanjing to report the results.

"Your Highness, it's done! It really happened! Yang San said excitedly, a little incoherent.

My father made a loom, so he got an official position, although it was just a symbol and had no real power, but he was also an official when he said it.

Yang San is looking forward to whether Li Yuanjing will also give himself an official next? Don't ask for too much, just give an official from the ninth grade, with Yang Li's example, Yang San feels that there is still a lot of hope.

"Try it!" Li Yuanjing looked at the excavator that seemed to be different from his memory, and said with interest.

"Okay!" Yang San responded and directly put the excavator in his arms on the ground.

It's very rudimentary, there are no wheels or anything, it is built on a wooden board as a base bed, but these are not important, and they will be added in the future.

On the arms that are not too long, there are three rows of gears that do not disturb each other, and they look very precise and very deep.

In fact, there are not many actions to be done by the excavator, only need to be able to stretch the arm back and forth, be able to lift the arm up and down, and the bucket can be moved.

But these three requirements were completed by dozens of gears of different sizes in Yang San's hands.

The operating lever is two turntables located on both sides, only to see Yang San rotate briskly, the arm began to move forward rapidly, the other turntable rotated slightly, the arm moved up relatively slowly, and then began to rotate the turntable in the middle, the bucket began to change the position, at this time the state of the excavator has entered the state of work.

Immediately after, Yang San began to manipulate his arm downward, trying to dig out the clods of soil on the ground.

However, this step ended in failure, and the clods of soil in the ground were not dug up, and even the bucket did not enter the ground.

Yang San scratched his head a little embarrassed and said, "Your Highness, it may be that the soil here is too hard, if it is looser, it can really be dug up." ”

"Good! Good! Good! Li Yuanjing shouted three times in a row.

Although the experiment failed, Li Yuanjing knew that it had succeeded when he saw that he could manipulate the robotic arm.

The soil on the ground cannot be dug because the bucket is wooden, the overall weight is not enough, and there is no specially manufactured bucket, if you change to an iron one, you can definitely dig it down.

"Split each part, and then enlarge the ......" Li Yuanjing thought about it, and then looked at the excavator on the ground, there should still be a problem after magnification, and Li Yuanjing is most worried about the problem of needing several people to manipulate.

The reason is still the same, the bigger the machine, the greater the force that needs to be pushed, and considering that the ability to travel is too poor, it can't be built too big.

In fact, the one in front of me is not even a meter long, considering some other factors, the counterweight ratio or something can be ignored, just dig a soil, don't be so selective.

Thinking of this, Li Yuanjing had a certain number in his heart, directly took over the control, manipulated his arms to a flat position, pointed to the two ends and said: "From here to here, the length of the middle is two zhang, the length of the main body is eight feet, and the bottom is made of a horizontally rotating setting, and the wheels must be added, all made of iron, and the gears or something must be made of steel. ”

Cheng Chumo was dumbfounded as he watched from the sidelines, obviously a failed thing, why not improve it, but increase investment? What if it doesn't work after that?

"Your Highness, do you want to think about it again?"

Cheng Chumo's persuasion made Yang San a little depressed, but he still mustered up the courage to say: "Your Highness, in fact, my father has also discussed with me about the problem after magnification, if the manpower is really difficult to control, it can also be controlled by cattle or horses when necessary, but this seems to be a bit small, but the horizontal rotation can be controlled by cattle and horses, so it shouldn't be a big problem." ”

"Your Highness, something happened...... Something went wrong......"
