Horror Game: Inheriting Trillions of Ghost Money from Ancestors

After opening the door, the white papers floated out of the room.

Chen Xun looked into the room. The walls of the room were covered with dense runes and words.

An old man wearing thick glasses sat in front of a table, holding a pencil in his hand, constantly writing and drawing on the white paper on the table.

"I can't figure it out, I really can't figure it out."

"Why is this thing so difficult?"

The ghost said, and then tore off a piece of white paper and threw it behind him.

The white paper immediately floated in front of Chen Xun.

Chen Xun took the white paper with one hand and looked at it.

Then he was stunned.

Because on this white paper, there was actually a series of functions.

The ghost in front of him was actually using these functions to calculate some questions.

Mathematician ghost?

Chen Xun paused.

Although he admitted that his academic performance was indeed quite good, he would also have a headache when facing these math problems.

Moreover, Chen Xun looked at the mathematician ghost.

This guy looked particularly crazy, and it was unknown whether he was mentally normal or not.

Chen Xun walked in.

The floor of the room was covered with scattered white papers and half-used pencils.

Even the quilt on the bed was painted with various symbols.

The moment Chen Xun walked into the ward, the mathematician ghost looked back.

The eyes stared at Chen Xun through thick glasses.

"Nurse, who told you to come in? Get out!"

"Do you know that because of your rash intrusion, my thoughts just now were all interrupted?!"

"I have been calculating for a long time!"

"What are you going to use to compensate me!?"

"Your stupid head or your heart?"

The mathematician ghost said, and the ghost spirit on his body suddenly emerged.

And Chen Xun also paused, and silently took out a baseball bat from the system space.

Chen Xun is not a player who can be bullied by ghosts at will.

But in the next moment, the eyes of the mathematician ghost were stunned.

"I thought of it, I thought of it."

"This way of calculation, this calculation will definitely prove this problem!"

The mathematician ghost said, and immediately turned to look at the white paper in front of him.

Then he continued to write and draw with a pen.

But not long after, he began to stop, and then his hand kept scratching his scalp.

Chen Xun looked at the bald scalp of the mathematician ghost, and the whole person was stunned.

Then he slowly walked in and finally saw the problem on the desk of the mathematician ghost:

Assume that $f(x)$ is a continuous differentiable function about $x$, and satisfies $f(0)=0$$f(1)=1$. Proof: For any set of Sn+1S different real numbers $x_0,xl,cdots;x_n$, there exists a set of $n$ real numbers $t lt 2,cdots,t_n$, such that $$sumlimits_{i=0)n(-1)~if(xi)binomn)i}=n!sumlimits {i=lnfrac{f(t_i))(prodlimits_{j=l,jeq i)~n(t_i-t_j)}S$

......

? ? ?

When Chen Xun saw this question, his eyes widened, and his face was full of disbelief.

Is this... a question that humans can come up with?

Even though Chen Xun is a high school student now, he was completely confused when he saw this question.

Now, let alone asking him to calculate, he can't even understand the question!

Chen Xun was stunned.

The next second, the mathematician ghost turned around and looked Chen Xun up and down.

"Nurse, it was because of your rash intrusion just now that I lost my train of thought."

"Now, you come and prove this problem for me."

"Otherwise... I will drain your blood and make it into ink."

At this point, the mathematician ghost suddenly exuded a strong ghost aura.

Chen Xun was also surprised.

Aren't these mathematicians trying to make trouble for him just to enjoy the process of solving these problems?

Why let him solve it now?

Chen Xun looked at the mathematician ghost and said:

"Old man, you solve this thing just to prove this problem yourself?"

"What do you mean by me solving it?"

Hearing Chen Xun's words, the mathematician ghost paused, and then said:

"Who said I wanted to solve it myself?"

"I just had to do it."

"I need to useThis answer, in exchange for my lost memory!"

The mathematician ghost said, and immediately took out a ghostly wooden box.

There was a small note on the wooden box.

The note had the math problem that Chen Xun had just seen, and a line of small words:

"Please prove the above problem. After the successful proof, the box will automatically open."

"Your memory is inside."

The moment Chen Xun saw the box, he was also stunned.

"Is this box filled with your brain?"

"Who put your brain in it?"

The mathematician ghost said:

"It was me!"

"Wait, the thing inside is not a brain."

"When I had a premonition that my memory would be taken away by that guy who drew pictures, I wrote down some important things in a diary. Then put it in this wooden box. "

"And, I wrote a math problem on this wooden box. As long as I can solve this math problem, I can open this box and retrieve my important memories through the clues inside."

"But I forgot one thing. After I lost my memory, I couldn't even solve this math problem."

Chen Xun stared at the box, and then his mouth twitched slightly.

I thought to myself, if you can't solve this math problem, why do you still make such a difficult problem?

Isn't this just making things difficult for yourself?

Chen Xun took the wooden box and said:

"In that case, then I can help you open this box, right?"

There may be some clues to the main task in this box.

However, Chen Xun couldn't understand the problem, so he could only try to see if he could open the box directly.

Hearing Chen Xun's words, the mathematician ghost shook his head immediately:

"It's useless. This box can't be opened at all except after solving this problem. "

But before the mathematician finished talking, Ying appeared beside Chen Xun and took the wooden box.

"Haha, it's just opening a wooden box, what's so difficult about that?"

"If it doesn't work, at most you can just break it, right?"

Ying started to play with the wooden box.

But the mathematician was disdainful:

"It's useless. When I designed this wooden box, I must have arranged a lot of complicated mechanisms."

"These mechanisms can't be opened casually."

"Besides, I must have made a whole set of protective measures."

"If someone wants to forcefully open this wooden box, the protective measures will be triggered."

"Then the diary inside will..."

"Click..."

Before the mathematician finished talking, he heard the sound of a lock being opened.

He paused and looked at Ying...
