Albert Einstein.

Lin Xian picked up the warm key from his clothes, turning it over in his hand to observe.

At first, Lin Xian didn't react to the string of addresses, but when Angelica mentioned it, he remembered reading reports about Einstein before.

The great man spent his later years in Princeton for more than 20 years, making Princeton his second hometown.

He taught at Princeton University and passed away in 1955 at the Princeton University Hospital at the age of 76.

It is well known that the head of the pathology department at the time, interested in Einstein's brain, privately dissected Einstein's head, stole his brain, and soaked it in formaldehyde.

To this day, Einstein's brain tissue is still stored in Princeton University Hospital, and scientists have conducted many studies on the great man's brain in recent decades.

But most of the research results are meaningless.

A very famous rumor, saying that "Einstein's brain development rate is only 10%" came from this.

In fact, Einstein's brain was not special compared to normal people's brains, except that it weighed a little more... after all, Einstein's head was indeed larger than the average person's, which is a matter of course.

Lin Xian also recalled.

Einstein was very low-key in his later years and had instructions for his death.

He told his children not to hold any commemorative activities or memorial services after his death, but to cremate him directly and scatter the ashes somewhere.

He also specifically told them to keep the location of the ashes secret from the world. His concern was that later generations would treat the place where his ashes were scattered as a holy place for visits and pilgrimages.

It seemed that Einstein was not a person who liked excitement and only hoped to leave this world quietly.

Einstein's children also followed Einstein's advice and did not hold any memorial activities for him. And the ashes were scattered in a place that no one knows... To this day, no one knows where Einstein's ashes were scattered.

Similarly, Einstein's former residence in Princeton is the same.

He wrote to Princeton University, asking not to treat his former residence as a museum or tourist attraction, but to let it flow into the market normally and treat it as an ordinary house.

Princeton University also respected Einstein.

In the following decades, many people lived in this old house where Einstein had lived, and there was nothing special about it.

Lin Xian didn't know why Ji Lin wanted to buy this house.

What's more, he didn't understand what was special about this broken house compared to Ji Lin's assets of hundreds of millions of dollars.

"Is this the only key?"

Lin Xian looked at Angelica:

"Nothing else?"

Angelica shook her head:

"Until Ji Lin's death, Ji Lin and I actually kept in touch. We grew up in the same orphanage when we were young, and then we were taken to the old man's side to be raised. I am several years older than Ji Lin. I basically held him when he was growing up in the orphanage."

"Later, we were taken to the old man's side, and we separated soon after. The old man sent me to Hollywood to debut as a child star and started in the film and television industry. Ji Lin stayed with him and was taken care of by his niece... who later became Xu Yun's wife."

"Ji Lin and I have a good relationship, but we don't have many opportunities to meet every year. We just send emails and chat online. Some time ago, Ji Lin told me that he had made a good friend, his first good friend in life."

"I was quite surprised. Would someone befriend such an awkward little boy like him? Ji Lin also told me some things about you, but not much. He just said that it felt good to have a friend. I don't know much about other things."

"He left very suddenly, without any warning. I don't know what he was thinking or what happened. But I can roughly guess... it should be related to him and the old man's secretive, hidden things."

Angelica became a little lonely as she spoke.

Lin Xian looked at her:

"Would you be sad about their deaths?"

"A little bit, maybe."

Angelica nodded:

"But... I actually think they should have been mentally prepared for death a long time ago. Not only them, but also me."

She changed her sitting position, put down her legs, and looked out the window of the speeding business car:

"I was born in a war-torn area, where there is fighting every day and night, and relatives and friends die every day. On the day the old man picked me up, I was lying next to a scorched corpse, all my family, my parents, my brothers and sisters."

"From that time on, or even earlier, death was not an unacceptable thing in the eyes of children in our war-torn area. Everyone is numb and has long been accustomed to it. So you don't have to be so wary of me. I have no intention of coming to you for revenge. I have been used to death since I was a child and knew they would have this day."

"But Ji Lin is different. He has been looking for the murderer who killed his parents, but he has never suspected that the old man did it. I also believe this. Ji Lin often outwitted the old man. If it was really the old man who killed them, Ji Lin would have found out long ago."

"I have never known what they two are doing, but judging from your reaction now and the letter Ji Lin wrote to me..."

Angelica turned her head, her cold and beautiful face looking at Lin Xian:

"The ones who killed Ji Lin's parents, and the ones they have been chasing... are they all this organization called the Genius Club?"

...

Lin Xian didn't say anything.

He looked at the key he was holding in his hand, feeling the heat gradually disappear from it:

"I don't know."

He replied softly.

He still wouldn't answer any of Angelica's questions. That was an irrational and unsafe act.

Angelica wanted to know the truth about Ji Lin's death. That was her problem and had nothing to do with him.

"If you are really Ji Lin's friend, you should tell me."

Angelica frowned and stared at Lin Xian.

"If I am really Ji Lin's friend, I shouldn't tell you even more."

Lin Xian turned his head and looked into Angelica's brown eyes:

"If he wanted you to know, you would have known it long ago. Since he doesn't want you to know, there must be his reasons."

"To be honest, I have never completely cleared your suspicion of crime, but that's it. After all, I'm not a law enforcement officer. But I still kindly remind you, if you don't want to repeat the same mistake, don't wade into this muddy water. Ji Lin may really be hiding these things from you in order to protect you."

"Then why would he tell you these things?" Angelica also stared at Lin Xian.

"That's our problem."

Lin Xian replied.

...

A long silence fell between the two.

Angelica finally understood that the man in front of her was not as easy to deal with as she thought. Whether it was coercion, inducement, or playing the emotional card, this man was completely indifferent and resolutely refused to reveal any information.

She breathed out a long breath:

"Okay, if this is really a problem between you two. I want to ask you... If one day, you really find the Genius Club and find the murderer who killed Ji Lin's parents, will you help Ji Lin take revenge?"

"Of course not."

Lin Xian was really amused by this stupid question:

"Maybe Ji Lin didn't tell you what he was doing and who he originally planned to kill... but I think you must have some misunderstanding about the relationship between us. Why should I take revenge for him? It's just a coincidence that we are interested in some overlapping things."

"Then in that case, you should go to Princeton and take a look at this house at 112 Mercer Street." Angelica pointed to the key in Lin Xian's hand:

"Will you go?"

Lin Xian put the completely cooled key into his suit pocket:

"I probably won't go in the short term."

Lin Xian was telling the truth.

For his current situation, going abroad is too dangerous.

Dragon Country is undoubtedly the safest country in the world, and the United States is now in chaos. Who knows what dangers there will be?

In addition, it is still a mystery whether Copernicus in the Genius Club has noticed him.

Going abroad without sufficient security is very unwise and very dangerous.

Even the information left by Ji Lin... Einstein's former residence... is indeed very attractive. Lin Xian also has a direct feeling that these clues must be related to the Genius Club.

Only such important clues would make Ji Lin specifically ask Angelica to personally deliver the key to him.

What is hidden in Einstein's former residence?

"Hehe, I knew you wouldn't go."

Angelica smiled as if she saw through Lin Xian's thoughts:

"So I went to see it for you."

"Oh?"

Lin Xian became interested:

"What's inside?"

"There is almost nothing inside."

Angelica said:

"It's really empty, empty, with bare walls, nothing at all. All the furniture and extra objects were cleared away by Ji Lin. The only thing in the entire room... is an oil painting hanging on the living room wall."

"Oil painting?"

"It's a somewhat old oil painting."

Angelica looked at Lin Xian:

"The Sad Einstein."

...

Lin Xian narrowed his eyes.

He recalled the black and white painting he saw with Chu Anqing in the East Sea Exhibition Hall.

In the canvas, the old man's hair stood on end, his eyes were dull, like a zombie, a dead man.

His face was solemn, as if he had suffered a huge blow; he was listless, as if his soul had been hollowed out.

Lin Xian remembered it very clearly.

Oil paintings were known for their bright colors, but this oil painting completely abandoned the color advantages of oil paintings. Almost the entire canvas had only two colors, black and white.

Depressing.

Heavy.

Bleak.

Miserable.

Uncomfortable.

He vaguely remembered that Chu Anqing also read out the introduction of this oil painting -

Painted in 1952 by realist painter Henry Dawson in Brooklyn, USA.

It was already a painting from 70 years ago.

Lin Xian came back to his senses and asked doubtfully:

"Why did Ji Lin empty the entire room... and then hang up a fake painting."

"No, that's not a fake painting."

Angelica said seriously:

"Ji Lin's "The Sad Einstein" is a genuine product, indeed the genuine product painted by Henry Dawson back then, not a fake."

"That's impossible."

Lin Xian shook his head:

"At the end of last year, I also saw this oil painting in the East Sea Exhibition Hall. It was a global oil painting tour, and it was marked that the painting was genuine, from a well-known museum. I can't remember it."

"That one is of course also genuine." Angelica didn't care:

"But the one Ji Lin hung in the house is also genuine."

Lin Xian chuckled:

"You're making me laugh a bit. Can there be two Mona Lisas in this world?"

Angelica spread her hands:

"Da Vinci didn't paint two Mona Lisas, but Henry Dawson painted several The Sad Einsteins."

"Several?" Lin Xian was a little surprised.

"Yes."

Angelica nodded:

"Ji Lin clearly told me this, because the The Sad Einstein in his hand was bought by me for him."

"Ji Lin told me that The Sad Einstein hides a special code. Although I don't know if it was done by Henry Dawson or under Einstein's instructions. But according to the logic of the code on it..."

"There are a total of 8 The Sad Einsteins in this world."

8 paintings.

Lin Xian fell into deep thought.

He hadn't considered this possibility.

Strictly speaking, Da Vinci didn't paint only one Mona Lisa. It is said that there are actually several versions of this painting. There is an initial discarded version, but it has also been preserved.

But there are actually as many as 8 genuine The Sad Einsteins!

This must have been done deliberately.

Either Einstein instructed it, or the painter Henry Dawson did it.

In short, for some special reason, this painting, which is not particularly famous, painted 8 identical genuine copies.

What made Lin Xian even more concerned was...

According to Ji Lin.

The coded information hidden in these 8 The Sad Einsteins should be different and logically related, so he could deduce that there were a total of 8 genuine works.

What is the purpose of this?

What is the special meaning?

Suddenly.

Lin Xian understood a little... why oil paintings are not suitable for painting black and white portraits, but Henry Dawson still insisted on using oil paints -

Oil paintings are three-dimensional.

Oil paintings are different from ordinary paintings. They are painted with thick and hard oil paints, and the surface of the canvas is uneven and has height differences.

This gives the painting a sense of three-dimensionality and also opens up a third dimension, which may allow those codes that are not easily noticed to be hidden in the height and drop of the oil paints!

Lin Xian was an art student, and he thought of this in the first moment.

Could it be...

Is this the code that Einstein deliberately left behind?

If so, where do these codes point to?

Squeak————

The Alphard business car stopped, and the electric door on the right side of the car slowly slid open.

The small window of the soundproof compartment in the front opened, and the driver looked to the rear from the small window:

"The Peninsula Hotel is here."

Angelica looked at the pensive Lin Xian and smiled slightly.

She took out a business card from her handbag, and then took out an eyebrow pencil.

She pulled off the eyebrow pencil cap, wrote a string of numbers on the business card, and placed it in Lin Xian's hand:

"This is my phone number."

She stepped on her high heels and walked down the pedal, standing in the breeze outside the car, throwing her long hair scattered on her shoulders back, and a cool arc and fragrance slid through the air.

Angelica turned her head:

"If one day, you really plan to come to Princeton..."

She held out her left hand in the number six gesture and stuck it to her cheek:

"Call me."
