Dreaming about the world, embarking on the path of spiritual practice

…

"Mom and Dad, let me press it for you too!"

"Okay, let's try your skills too."

After the two elders experienced massage and sound therapy, the way they looked at Yu Liang changed instantly.

"Er smash, your ability is really too limited in this small shop.

Is there no money? Dad will pay for it, and we'll open a big club.

Your mother works as the cashier and I work as the manager. Business is absolutely booming. "

"Uh~"

Just when Yu Liang was thinking about how to answer, his father made a decision directly:

"Let's do it this way. Your mother and I won't go out and we will join the battle together as a family. Isn't this better than working hard outside to make money?"

"What do you think?" Dad turned to his mother and asked.

"Yeah, I think it's feasible." Mom nodded in agreement.

Seeing that the two elders were in such high spirits, Yu Liang followed their wishes.

This is good, the family can have fun together, and my parents are getting older, so they no longer have to work hard outside.

"Our club should be a high-end one with a membership system."

"Ersha, how many members do you have in this store now?"

"Twenty-seven ordinary members and forty-two senior members!"

"so much!"

Hearing Yu Liang's answer, both his parents exclaimed. A member with six thousand members must be hundreds of thousands?

"What are ordinary members and senior members?"

"Ordinary members can enjoy massage programs for free at 6,000 yuan a year."

"Premium members can enjoy a sound therapy project once a month by recharging or spending 100,000 yuan."

Yu Liang's answer was so shocking that the two of them were stunned for a moment after hearing it.

I thought to myself: My son has already earned millions from this small shop. If it can be expanded, it will be great!

"I'm going to inquire now to see if any club can't be opened, and I'll just give it up!"

My father left in a hurry, and my mother also picked up her cell phone to inquire about any stores that her colleagues could not continue to work in and were planning to change hands.

In the evening, my father used his many years of contacts to find out about a teahouse that was ready to be sold.

The family of three immediately went on a field trip.

This tea house is located next to a park in the north of the county. There are several old communities nearby, which is not bad in terms of location.

“Yixuan Teahouse!”

Yu Liang looked at the teahouse's facade. Its decoration was similar to that of an ancient teahouse.

"Hey, I'm here, right, right at the door!"

Dad called the owner of the teahouse, and soon a middle-aged man with a big belly walked out of the shop and greeted him with a smile.

Judging from his appearance, it is difficult to tell that this man is the owner of a tea house.

"It's Boss Yu, please. Nice to meet you!"

After shaking hands and exchanging pleasantries, several people entered the tea house.

Let his parents negotiate the price. Yu Liang didn't want to get involved, so he wandered around the teahouse on the pretext of visiting.

The tea house has two floors, with the lobby downstairs and private rooms upstairs. The decoration is elegant and simple, spacious and bright, and it is really good.

If you plate it down, you don't need to decorate it. You only need to change the house number.

You can continue to work at the teahouse downstairs and do some recuperation in the private room upstairs.

Yu Liang came to the door of the private room on the second floor and found that the private room here was extremely private.

The door is opened and closed via a green plastic card on the door.

When the card is inserted into the card slot on the door, the door will automatically open, and when the card is pulled out, the door will automatically lock.

Something suddenly came to mind.

I sent a message to my parents to tell them that he was very satisfied with the layout and decoration of the store, and they would leave the rest to them.

Then, Yu Liang returned home alone and looked up all the relevant information about electromagnetic cards.

In modern society, people use many kinds of cards, such as bus cards, bank cards, access cards...

These cards all cleverly use some electromagnetic principles.

General bank and credit card information is stored on the black magnetic strip on the back.

There are many small metal particles on the magnetic strip that form a queue. By changing the magnetism of the queue on the magnetic strip, various information is input into the magnetic strip.

It uses a technology called magnetic recording to convert digital information into magnetic properties on a magnetic core so that the information can be stored in a magnetic strip.

When a magnetic card is inserted into a card reader or sensor, the card reader reads the changes in the magnetic field on the magnetic strip through the sensor and converts it into a digital signal for decoding, thereby obtaining the data stored on the card.

There is a copper ring inside the access card, and the copper ring is connected to a chip.

When the access control card is swiped, the copper ring will cut the magnetic induction lines with the magnetic field released by the card punch to generate electricity, thus activating the chip to release information that is received by the clock card device.

…

Many applications of electromagnetic induction have been deeply integrated into people's lives.

It seems very magical, but the principle is actually very simple.

If you think about it from another angle, aren’t the immortal things in your mind, such as jade slips, sound transmissions, seals, etc., very similar to those made using electromagnetic induction?

Life is full of knowledge. Sometimes it’s not that you don’t know, but that you lack the eyes to discover!

Yu Liang thought about it and felt that although his magnetic field ability was still very weak at this time, he could use scientific means to amplify the weak power!

Wrap wire around a plastic water pipe.

Hold it with your right hand and quickly draw it with your left hand.

"Zi La~"

The electric light flickered faintly.

He raised his hand and pointed the water pipe at the unlit light bulb above his head, and the light bulb suddenly lit up.

"Perhaps, you can try to make an electromagnetic pulse device!"

An electromagnetic pulser is a device that can amplify electricity from a few volts to tens of thousands or even higher. Its working principle is to release energy instantly through energy storage elements, thereby generating transient current and voltage. This transient current and voltage can generate a strong electromagnetic field, thereby generating a pulse signal.

On the Internet, many people have made their own electromagnetic pulse devices. The materials used are also very simple, including batteries, resistors, capacitors, wires and a large iron nail as a discharge device.

Just when Yu Liang was thinking about how to make an electronic pulser and turn it into a weapon, his parents came back.

Seeing a water pipe wrapped in wires in his hand, he asked doubtfully, "What is this?"

"Oh, nothing!"

Yu Liang put it aside casually.

"Mom and Dad, how was the conversation?"

Dad said angrily: "We haven't agreed on the price yet, and that damn fat guy still wants to hoodwink me. Let's hang him out for the night and talk to him tomorrow!"

"Oh~"

Yu Liang nodded.

The three of them chatted about some trivial matters in life.

Seeing that it was getting late, they all took a shower and rested.

In the dream, Yu Liang traveled to the world of Xiaoao.

When his parents come back and it is inconvenient to practice at home, he will travel through time to practice.

With his current ability, there is no problem in rubbing a generator with his hands.

Return to Miao Village

Yu Liang had someone build a refining room for him and at the same time collected a large amount of magnets and copper.

In just four days, a hand-cranked generator was built.
