Prince Yu's Mansion set the sale time for the second batch of flower essential oils three days later.

This made the courtesans who were excited to buy the next day, the leading female troupes, the ladies and ladies of merchants, the ladies of officials, and the ladies of officials, and so on, all returned in disappointment.

Fortunately, everyone still has a try-in kit to send it.

I didn’t use up the ten thousand bottles I prepared yesterday, and I brought dozens of boxes here today. Anyway, all the ladies and ladies who have been here in the past two days have been sent.

When Luo Yun's maids were smiling and putting on trial suits, they did not forget to remind them that when they saw the flag of flower essential oil rising up on Miaowei Tower again, they knew that it would be on sale.

This posture has a very scent of "an arrow through the clouds, thousands of troops will meet each other."

These trivial things have nothing to do with Liu Mingqi.

He has been busy making various toilet accessories these days.

The schematic diagrams Liu Mingqi gave to the porcelain masters were all written in specific sizes. As long as they made them fine, there would be no problem with these accessories.

The greatest advantage of modern industry in people's livelihood is that it makes fine electrical appliances, furniture, etc. into unified standards.

Each thing is broken into parts. If it is broken, you can replace it with new parts, so it does not have to be scrapped as complicated as it is.

Liu Mingqi repaired the toilet himself in his previous life. When the toilet was full of water and overflowed, he bought a new integrated valve online according to the model. It was simply disassembled and installed, and it was able to be used normally again.

This is not because he is a PhD in physics, so he can do it so easily. In fact, an ordinary person can install and replace it according to the seller's video with a little hands-on ability.

Liu Mingqi cannot do an overall industrial structure now, but it is more than enough to standardize the rules and standards of toilets.

That day, while busy in the work room, Dazhu came to report that a fat man named Fang Lei asked for a meeting.

Fang Lei?

While Liu Mingqi was wondering, Dazhu said again. Fang Lei said that he knew Prince Yu and he was the one who made a bamboo dragonfly.

At this time, the young man suddenly realized and quickly asked Dazhu to bring him in.

After the little fat man was taken into the workshop, his eyes immediately began to shine.

"Huh, what is this for?" He pointed to the copper fairway floating above the copper tank.

"The buoyancy ball, and the whole set, is an automatic water inlet and water interception device based on the principles of buoyancy and leverage."

Liu Mingqi said and demonstrated to him.

After twisting the button, the outlet opening was opened, and the water in the copper water tank was put down. At the same time, the buoyancy ball fell down with the lever, opening the water inlet valve.

There is also a larger water tank on the copper water tank. The copper pipe connected between the two starts to slowly inject water.

When the hydraulic force drives the buoyancy ball upwards, the buoyancy ball also drives the water valve through the lever, blocking the water outlet.

When the water enters a certain position, under the principle of leverage, the buoyancy ball drives the water valve to block the water inlet.

In this way, the water outlet and inlet are stopped, but the water depth reaches the previous scale at the same time.

"interesting!"

Fang Lei pointed at him and said, "Criminal, can I touch him?"

"Yes, just do whatever you want." Liu Mingqi said first.

"Then I'm not polite!"

A flash of light flashed in the little fat man's eyes, and he immediately touched the buoyancy ball and began to look left and right.

After a while, he touched everything in the water tank.

Finally, he squatted down and looked at the water outlet, shook his head and said, "Criminal, your wallet door is not closed well enough, it's still dripping water."

"Then what can I do?" Liu Mingqi said, "With iron and copper things, they will rust over a long time. The buoyancy cannot push the water valve at all, and thus cannot rise and fall normally, which is useless."

"Too."

The little fat man touched the plug again, "Well, this is made of iron wood, but it won't expand after soaking in water for a long time... Prince, have you considered using spiral patterns to fit?"

This kid is quite promising!

Liu Mingqi glanced at the fat man without realizing it.

Although old craftsmen know that spiral patterns are more suitable for sealing objects, they can think of using spiral patterns to seal the water outlet at a glance, which is not something that ordinary people can do.

"Spiral locks can only be used in ordinary times. Now they still need the attraction of water to suck the plug back to the outlet. If it is spiral pattern, can they still rotate automatically and then fit seamlessly?"

Liu Mingqi's faint rebuttal made the little fat man smile embarrassedly.

"Actually, I have also tried to use pig urine bags as a genus wedge, but its disadvantage is that it will break after a few times." Liu Mingqi sighed, "If I could find a thick soft material that is not crushed by water, which can perfectly stitch the water outlet, how great it would be!"

"This material does not exist, right?" the fat man shook his head.

"For masters of the art of mechanism, there is no problem that cannot be solved, but we have not found it yet." Liu Mingqi shrugged.

If you want to find rubber trees, you have to go out to the southeastern island rainforest and then refine and make rubber, which is another industrial problem.

Compared to this, it is easier to find oil, but the effect of rubber is never replaced by plastic.

At least in the current technological environment, it cannot be replaced.

The little fat man nodded and said to Liu Mingqi: "Criminal, why don't I come to your workshop to work? You don't have to teach me anything, just let me watch you do things."

"How is that possible?" Liu Mingqi shook her head seriously, "Fang Lei, you have called my master before, so I can't help but teach you... Come and take it!"

As he said that, he handed over a thin book to the fat man.

The little fat man took it curiously and took a look. At first he showed doubts, then his eyes lit up, and then his eyes became brighter and brighter.

In the end, he turned around and ran out without saying a word.

Early the next morning, when the little fat man came to Prince Yu's mansion again, he had two dark circles on his face, and he obviously had not fallen asleep all night.

But he was still very excited, "Master, what you said can only burn with air is so interesting, it's true!"

"What are your experiences?" Liu Mingqi asked while busy.

"I put paper and firewood into all three porcelain bottles in my house, and then covered them." The little fat man said, "So the largest porcelain bottle really burned the longest time, and the smallest porcelain bottle, the fire went out in a while.

This proves that you are right, Master! The amount of air determines the length of time the fire can burn, and the two are inevitably related, and the amount of fire and the size of fire burning have nothing to do with whether you can continue to burn."

Naughty kid!

Your mother didn't beat you to death, you're lucky!

Liu Mingqi smiled and shook her head.

"But the heat energy will not disappear out of thin air, it will only form another form of energy... I am not deep enough to understand this." The little fat man continued: "For example, the three porcelain bottles in my house, it turns out that the fire inside was extinguished in the end.

Although the high temperature caused by combustion is transmitted to the porcelain bottle, making the porcelain bottle hotter, the porcelain bottle finally returned to cold? Where did this heat go?"

It is already good that Fang Lei can think of the fire being passed on to the porcelain bottle.

Liu Mingqi couldn't help but look slightly, "Of course it dissipated into the air in your room."

"In the house?" Fang Lei frowned, "Can you want to tell me that these heat energy has reached the air, so it will make my house hot?"

"When you did this, didn't you find that the house was hotter than outside?"

"Well, I feel a little bit." Fang Lei nodded and said, "I used to think that the fire would naturally make the room hot, but I didn't expect it to be just a transfer of heat!"

"Then can you tell me that the temperature in the room finally returned to its original state. What is the reason?" Liu Mingqi asked heuristically.

"That's because..." Fang Lei thought for a while, "The heat in the room has been emitted outside the house again! And why I didn't feel it outside the house is because the heat was dispersed by the wind!"

"clever!"

Liu Mingqi put down her work and compared her thumbs seriously, "Boy, you are a genius who learns this knowledge!"

Fang Lei was not proud, but bowed to Liu Mingqi and said, "Master, please teach me more things! First of all, I want to learn how to send people to heaven to see!"

It was not until last night that Fang Lei sincerely admired this young man who was not much older than him.

Therefore, his name changed from "prince" to "master".

"That involves a lot of knowledge!" Liu Mingqi nodded, "I call this related subject 'physics', you have to remember it."

"Physics, physics...the truth of all things...Master, you are so knowledgeable!"

The smart Fang Lei has learned it without a master.

Including flattery.

"But don't worry now, come and help me." Liu Mingqi pointed to the white porcelain toilets in front of her, "First see how I installed the first toilet, and then you can make the rest."

"good!"

Fang Lei arrived in front of him excitedly.

He is worthy of being a man who can fly with bare hands. After watching for a while, he skillfully began to assemble the remaining toilet buoyancy balls, gate valves, levers, water inlet valves and other components.

Liu Mingqi sat leisurely and drank tea, asking him casually: "Do you know why I have to polish these parts to the same size?"

"Imitate the powerful crossbows from a thousand years ago." Fang Lei said while working: "Only when the parts are unified in specifications can they be made universal and better repairs of these things."

The boy nodded slightly.

Although the little fat man looks stupid, he is actually very smart and knows a lot.

"It's done, Master!"

After a while, Fang Lei tried the toilets one by one.

Although he had not poured water in, he already understood the principle and knew the good or bad.

"Okay, then go to the palace with me to give gifts!" Liu Mingqi said lightly.

Needless to mention the inheritor of physics, a little apprentice who can do beautiful jobs is still very useful.
