After the documents were handed over to Ma Xiangdong, he flew to Hong Kong Island at an extremely fast speed.

Lou Xiao'e, who has already established a foothold in Hong Kong Island, received a letter from Li Weidong early in the morning.

After getting the documents, I immediately acted according to Li Weidong's instructions.

In this era, it is not easy to apply for a patent, especially applying for a foreign patent.

But given the trend of banknote capacity, those relevant personnel directly gave the green light.

The first ones to download are naturally the patents of Niu Buluo and Hong Kong Island. Others will have to wait for a while.

In order to prevent Li Weidong from waiting too long, Lou Xiaoe sent the two patent registration documents back to the mainland first.

Naturally, the path taken is still the same as that of Runhua Company.

Since this is a document sent back to the Mainland, it will inevitably undergo some inspection.

People who saw the patent document reported the matter directly.

Although today's Runhua Company is developing well in Hong Kong, it still lacks some key pillar industries.

The emergence of solar panels gave them a glimmer of hope, an opportunity to join hands in the two pillar industries of hydropower.

Nowadays, the two power generation companies on Hong Kong Island are in the hands of Gui Lao, leaving the mainland with no chance to intervene. The situation will not change until the Daya Bay Nuclear Power Plant appears decades later.

If you can't hold water and electricity in your hands at the same time, you will lack enough right to speak, and it will be difficult to make some rebellious people obedient.

Now Runhua Company sees an opportunity. Even if it cannot control the power supply of Hong Kong Island, it can still have some say.

This can already change a lot of things.

So the current head of Runhua Company made a decision after asking for instructions from above.

This decision flew to the capital along with the two patent documents.

‘“A sneeze, a sneeze!”

Li Weidong sneezed several times in succession. Seeing his appearance, Yu Li asked worriedly: "Weidong, are you okay?"

Li Weidong shook his head and said: "It's okay, help me get the iron wire over there!"

When Yu Li immediately ran to get the wire for Li Weidong, Yu Haitang came over.

"Brother-in-law, is this how your solar panels are made?"

"What is the problem?"

"No, I originally thought I would need some fancy tools, but I didn't expect you to just rub it out with your hands."

Yu Haitang felt a nagging feeling in her heart. She really didn't expect Li Weidong to be able to make solar panels purely by hand. It was beyond her expectation.

Li Weidong didn't know how to explain it to her. After all, his hands-on ability had already exceeded the range of ordinary people.

Not to mention hand-rubbing solar panels, if given the chance, he would also like to try a hand-rubber machine.

After all, even if he conquered the problem of nuclear fusion, it would be in vain if he couldn't do it.

Copper sheet, ferric chloride solution, alcohol, tin plating, double layer capacitor...

Eight sets of solar panels were quickly produced.

Naturally, these solar panels are given to relatives and friends.

He Yuzhu had been coveting it for a long time. After getting the news, he rushed to Li's house in less than ten seconds.

Li Weidong taught He Yuzhu how to install solar panels.

"You can install it yourself. I still have something to do?"

"Is there anything more important than helping me install solar panels?" He Yuzhu was a little timid. This thing is high-tech. If it gets damaged, he will lose a lot of money.

"Help my father-in-law install it."

"..."

Although Si Zhu thinks he has a good relationship with Li Weidong, he is not arrogant enough to compare with Yu Jia.

...........

When Li Weidong drove Yu Li to the Yu family, in addition to the old couple of the Yu family, even Uncle Yu and Fatty Yu were already waiting.

Seeing Li Weidong take out the solar panel, Uncle Yu walked up, looked at it, shook his head and said: "Weidong, this thing of yours is not as good as my new discovery."

Li Weidong moved a ladder and climbed to the roof. While installing solar panels, he continued: "Uncle, are you always engaged in scientific research?"

"Of course, I am a great scientist!" Uncle Yu said proudly: "I have discovered the secret of sheep climbing trees. Maybe it won't be long before I can get the big red flower from the ministry."

Li Weidong almost fell off the roof, held on to the ladder and took a breath.

"Awesome! When you get the big red flower, I will invite you to take a bath in Tsinghua Pool."

"Don't you want to know the secret of sheep climbing trees?"

Li Weidong's calmness made Uncle Yu a little puzzled. He had just discovered "Sheep on a Tree", but it shocked Fatty Yu.

Li Weidong waved his hand: "Uncle, you should keep those secrets and exchange them for some pig intestines."

Just kidding, he has no interest in being taken advantage of by others, not even Uncle Yu!

Fatty Yu almost laughed out loud, and Uncle Yu became even more depressed. He waved his hands and said, "Young people nowadays really don't have any enterprising spirit!"

After saying that, he held a physics book and read on the stool.

...

This is the second solar panel that Li Weidong has installed. Practice makes perfect, and it only took less than twenty minutes to install it.

Fatty Yu gently pulled the light cord and saw the incandescent light bulb in the room light up after flashing several times. His eyeballs almost fell off.

"Hey, be a good boy. I thought you were joking, but I didn't expect it to actually work."

"Of course, my brother-in-law is the best."

When Yu Haitang saw Li Weidong coming down, he hurriedly poured a cup of enamel tea and brought it over: "Brother-in-law, you have worked hard. Come, drink some water to moisten your throat."

Li Weidong took it and took a small sip.

Gee, it's so sweet, honey is put in it.

My sister-in-law is really good at handling things.

While I was drinking honey water, the door of the small courtyard was pushed open from the outside, and a large group of people came in, all of whom were nearby neighbors.

Although there is no self-media these days, the mouths of ladies are as loud as trumpets, and the speed of news dissemination is not slow at all.

Everyone was curious when they learned that the Yu family was going to install an object that could generate electricity under the sun.

After checking the line, several young wives immediately started talking.

"Hey, it's true that the lights can turn on without turning on the electricity."

“The Yu family won’t have to pay the electricity bill anymore!”

"I think Yu Li is a good husband. Being a driver earns a high salary, and now he can make small inventions."

"Little invention? Let me see, this invention is not small. Think about it, how many people are there in our capital? If they all have this thing installed, it will save my old nose a lot of electricity."

........

What surprised Li Weidong was that although the residents looked envious, no one asked him to help him make solar panels.

Not to mention having sex for free!

It seems that people's thoughts are still very simple these days, only the residents of the courtyard are weird.

The screenwriter must have put in a lot of effort to bring so many great minds together in one compound.

When Yu Li heard her neighbor's words, she felt happy. As a woman, who doesn't want to marry an excellent husband?

Yu Haitang's expression was a bit strange, sometimes happy and sometimes sad, but her eyes never left Li Weidong.

At this time, Yu Li was preparing meals in the kitchen, the Yu family was entertaining the neighbors, and Uncle Yu was sitting under the wintersweet tree and only read books from sages.

The only idle person in the courtyard is Fatty Yu.

Yu Haitang's weird behavior should have been discovered by Fatty Yu.

However, Fatty Yu was making small calculations in his mind at this time.

Solar panels are so useful. If you ask Li Weidong to make a batch and sell them in the pigeon market, you will definitely make a lot of money.

As for the required materials, it may be difficult for ordinary people to obtain.

However, Fatty Yu has been running the pigeon market for many years and has a large network of contacts. Those materials are not contraband, so it is not too difficult to get a batch.

Solar panels are considered an exclusive source of supply, and he can definitely take advantage of this opportunity and make a lot of money.

What Fatty Yu didn't expect was that Li Weidong immediately rejected him after hearing his idea.

"Weidong, if you think about it carefully, this is a big business, comparable to how many mountain products we have worked so hard to sell."

Li Weidong pulled Fatty Yu into the room, stared into his eyes and said:
