In the office, Edison was looking at the report card in his hand and sighing.

Although the incandescent lamp that illuminated later generations was invented by him (it is also said that the Englishman Swan invented it), due to the problem of longevity, the promotion of incandescent lamps was not so smooth.

In fact, it was the tungsten filament processing technology invented by Kulich in 1909 that played an important role in the promotion of incandescent lamps.

If the problem of longevity cannot be solved, it is impossible to completely promote incandescent lamps. Faced with this problem, Edison was also distressed, he did not think about finding a material that could replace carbon filament as in the past, but it has never been fruitful...

Just as Edison was still frowning about the filament, there was a knock at the door.

"Come in...", putting aside the report card in his hand, Edison raised his voice.

With permission, Edison's secretary walked in from the outside. "Sir, a Chinese named Yan Shao wants to see you..." When he said this, the secretary's face was somewhat different, obviously he had also heard of Yan Shao.

"Chinese?" Hearing this name, Edison also felt a little familiar, and only remembered it after half a ring. "It's the Chinese who wrote the novel!"

Of course he had heard of Yan Shao's fame, not to mention those novels that could be called classics, just the identity of the survivor of the Carante had been hyped by newspapers everywhere. Edison had not only read the relevant newspapers, but also read several of the novels, so naturally he would not have been unimpressed by the name.

But it was precisely for this reason that he couldn't figure out why Yan Shaowei would look for him...

After all, there is really no connection between the two people's industries, no matter how prestigious they are in their respective industries, after they go to each other's industries, they can only be regarded as laymen among laymen...

"That's right—" hesitated, and the secretary spoke. The Chinese said that he had invented a filament that lasted longer than carbon filament..."

"What?" Hearing this, Edison fluted for a moment, and only reacted after half a ring. "Really?"

"It shouldn't be fake, because the Chinese has already applied for a patent..."

Standing in the lobby, Yan Shao looked around...

"Mr. Yan, please go this way..."

Yan Shao didn't wait too long, and soon someone connected him to Edison's office.

The moment they stepped into the office, Yan Shao and Edison were observing each other.

For Edison, the Chinese in front of him was a completely strange existence, he had heard reports about the other party, and even read novels written by the other party, but he had no idea what kind of person the other party was.

In fact, in this regard, Yan Shao is almost the same as Edison...

Yan Shao's impression of Edison mostly comes from later generations, and in later school textbooks, Edison is usually set up as a role model for students. But on the Internet, he is also famous for his dispute with Tesla...

Edison and Tesla have always had a dispute over the power supply system.

In order to combat Tesla's invention of alternating current, Edison used alternating current to kill animals such as cats and dogs, and even had a circus elephant Topsy—————— which would definitely be accused of animal cruelty by animal rights activists in later generations.

Later, in order to give the public the impression that alternating current is dangerous, Edison also participated in the development of electric chairs. However, William Kemler, the first torturer in history, was unable to breathe with the first electric shock, and the second electric shock caused his subcutaneous blood vessels to burst and bleed, and his body was on fire, but he still did not die. William Kemmler did not die until the third electric shock, but it was eight minutes after the execution, when a witness described it as "a horrible and frightening scene, far worse than hanging."

Frankly speaking, this somewhat affected Yan Shao's impression of Edison.

However, Edison didn't care about how Yan Shao was, he was most concerned about today's business.

So after walking into the office, Yan Shao nodded slightly to Edison.

This is not polite, but a kind of respect.

Putting aside the fact that Edison invented countless things in his lifetime and greatly promoted the progress of mankind, these are indisputable facts, and these alone are enough to win Yan Shao's respect.

Seeing Yan Shao nodding at himself, Edison also nodded slightly.

"I heard that you have invented a filament that lasts longer than carbon filament, I wonder if this is true?"

Without too much politeness, Edison went straight to what he cared about most.

"Of course...", Yan Shao explained in detail.

When Edison learned that the filament invented by Yan Shao was tungsten filament, he was obviously stunned for a moment.

"Tungsten—" After a moment of silence, Edison looked up. Isn't it going to be a little too brittle..."

"It's because this problem has been solved to some extent that I dare to come..."Yan Shao took out a document from his briefcase and handed it to Edison...

Anyway, he has already applied for a patent, and Yan Shao is not afraid of being looked at by others. And the above is just a general explanation of the content about tungsten filament, and there is not much contact with the details, so there is nothing to worry about...

When he saw the contents of the document, Edison's eyes lit up.

Because what is written above is not only about tungsten wire, but also about the processing and production process of tungsten wire.

"Do you have a sample with you now?" I'd like to test it first..."

"No problem..."

Yan Shao didn't think that just talking in vain could make the other party obediently send the money to the door, so he happened to bring a few samples over this time.

After taking the sample, Edison motioned for Yan Shao to follow.

The company itself also has a laboratory, and it is that laboratory that Edison took Yan Shao to.

When the tungsten bulb was lit, Edison intuitively told himself that this was the filament he needed, a filament that would push the incandescent lamp to the core...

Although he was very excited in his heart, Edison didn't show it, but just motioned for Yan Shao to sit aside...

"I don't know how you plan to trade? Will we sell this patent directly to our company, or..."

"Of course it was sold directly..."Yan Shao said with a smile.

What he lacks now is a large amount of money, so even if the long-term flow can ensure that he has no worries about food and clothing for the rest of his life, he has no intention of doing so—————— then again, if his plan can be successful, then the little money from the patent, I'm afraid he won't be able to look down on it...

"Sell it directly...", Edison spoke. I don't know what your asking price is..."

Smiling slightly, Yan Shao spoke.

"Six million...... dollars..."

There is always a bargaining process in business, so he opened his mouth wide at the beginning
