After time travel, my best friend and I exchanged supplies and became a rich woman

At this time, Prince Yong'an also came over, pouting like his father, listening to Chen Dongyue's explanation.

Chen Dongyue continued: "Although we can only see the putter moving up and down now.

But what if we added a lateral axis to the pushrod?

Then, what will happen if we add a vertical axis to this horizontal axis? "

"That......"

Although Prince Kang understood everything Chen Dongyue said.

But I only half understand it.

He looked at his second son.

Very good, the second son's eyes are clearer than his own.

Chen Dongyue saw that the two men's eyes were facing each other, but they were speechless. She thought that it would not be too good for the prince, so she quickly answered the question herself: "Then this force is transmitted to the entire device through another axis. The end?

Now let's imagine this small part is twenty times as big. If we install a hammer at the end of the device, will the hammer be able to strike iron by itself through the conduction of force? "

"......Then the water can't be cool?" King Kang raised a small question.

"Of course," Chen Dongyue nodded, "The entire machine runs on steam, so the water must be kept and the steam must continue to be generated."

"Why don't you just forge the iron yourself after all this effort?" Prince Yong'an said.

Just when Chen Dongyue wanted to refute, she heard Prince Kang scold him: "You said, forging iron or making fire, which one is more laborious?"

It's almost the same, it's quite strenuous, this is what Prince Yong'an, who has never done any work, thought in his heart.

But since his father has asked this question, he must answer what his father wants to hear, "It's still more difficult to strike iron."

"Also," Chen Dongyue was afraid that the father and son would be addicted to blacksmithing, so she could only guide them, "If this thing was a hundred times larger, and then added with different transmission shafts and gears, it would have even more functions.

Princes and princes, please think about it carefully. In fact, the principle of this machine is very simple, which is to convert the heat energy of steam into usable kinetic energy.

If you two really grasp this point and think about it, you will definitely be able to create many, many good things. "

As soon as Chen Dongyue finished speaking, she heard a female voice from behind: "Ah, what are you doing?"

The visitor is Princess Kang.

She heard Qi Fang report that Prince Yong'an had returned with Chen Dongyue.

I originally thought that Chen Dongyue was coming to visit Princess Kang, so she waited and waited, but no one was there.

When Qi Fang came out to ask, it was actually said that Chen Dongyue had gone to the prince's study.

So Princess Kang came looking for her.

But as soon as she entered the study, Princess Kang saw three people pouting in front of the desk, muttering something unknown.

Is this true? !

So she couldn't help shouting.

King Kang, who was listening to Chen Dongyue's words engrossedly, his brain almost boiling, was startled by Princess Kang's voice.

Also shocked was His Highness the County Prince, who pretended to be serious, but his mind no longer wanted to turn around.

The father and son turned their heads in opposite directions at the same time.

'Bang! 'With a sound, the two heads hit each other, making a dull sound.

Good head, cooked. Chen Dongyue thought to herself.

The two men covered their heads in pain and squatted on the ground wailing.

Princess Kang was horrified and shouted: "Come here, come on, come on, come on, come on, why are you standing there in a daze! Go and help someone! Qi Fang, hurry up and call the doctor."

Prince, how are you? Is anything okay? Fu'er, Fu'er, how are you? "

The originally quiet study suddenly became chaotic.

King Kang covered his head and glared at his son, "Is your head made of iron?! You almost opened it!"

Then he raised his head and yelled angrily at the princess: "Okay! Stop shouting! My head already hurts, and it hurts even more when you shout like this!"

The princess said aggrievedly: "I am also worried that something will happen to you, so you are still complaining about me..."

It's not like she was the one who knocked the brains out.

Chen Dongyue didn't want to hear the royal couple arguing, so she planned to sneak to the door, shout at the top of her voice, and run away.

Unexpectedly, this person raised his leg and was stopped by Prince Kang, "Chen Dongyue, wait..."

Vomited.

He actually vomited! !

Chen Dongyue's first reaction was that my mother's name actually made people sick.

Then the second reaction was, oh, this man may have been hit by his son and suffered a concussion.

Good guy.

Prince Yong'an's head is indeed iron!

When the princess, who was still a little aggrieved, saw that King Kang had vomited, she instantly transformed into a screaming chicken and shouted to the eunuchs and maids to hurry up and fetch the doctor.

Seeing that Prince Kang seemed to be looking forward to his death, Chen Dongyue had no choice but to step forward and said: "My lord, please rest well first. If there is anything you don't understand later, you can have someone come to see the woman. I promise, I'll be there as soon as I can." .”

King Kang, who finally felt relieved, tilted his head and fell into the arms of eunuch Shuangxi.

"Father!! Father, what's wrong with you?!" Prince Yong'an didn't care that he had a horn growing on his head at this moment.

He jumped directly on King Kang and screamed.

King Kang suddenly opened his eyes and cursed: "Cry#@￥@#%@!#!!! I'm not dead yet!!! Shut up, I'm going to vomit again if you scream again!!!" "

Prince Yong'an was relieved.

Chen Dongyue quickly said goodbye to him and the princess.

Prince Yong'an, who was wearing horns, wanted to send her out, but Chen Dongyue declined, "Prince, you should let the doctor take a look at the bump on your head. It's really big."

Anyway, I won't leave Liaocheng. I'm usually either at Zhuangzi or in the academy. If you have any questions, you can always come to me. "

"You still have an academy?!" Prince Yong'an was very surprised.

Chen Dongyue thought to herself, stop nagging, your father is going to faint!

So she simply replied, "Yes, there is a small academy, just on Xiaoheyan Lane. Go and help. If you need anything, you can come to me at any time. I'm leaving now. No need to send you off. Goodbye."

At this time, the doctor just arrived.

Chen Dongyue took the opportunity to put aside her legs and walked out quickly.

Until she reached the door of the palace, she always felt that she had forgotten something.

I tilted my head and thought about it...

"Oh~~~~I didn't come on horseback today! No wonder I seemed to have forgotten something."

After saying that, she lifted her legs and left.

Anyway, the palace is not far from Jinyifang. She plans to go to Jinnyifang to have tea later and wait for the bus home.

Hehehe, it’s nice to have a shuttle bus.

Look, isn’t this useful again? !

But after walking two steps, I heard someone shouting from behind: "My boss!!! My boss is waiting for us!!!!"

Chen Dongyue turned around.

Slap the legs.

Oh, come on, it turns out that what I forgot was not the horse, but my two girls!

She said how could she remember what she had forgotten so quickly? It turned out she was wrong!
