Film and TV: Traveling through countless worlds at the same time

Zhuang Mohan was immediately interested when he heard this: "Did you make that Zhenlong too?"

Lu Xiao said, "Yes."

Zhuang Mohan's eyes flashed with a desire to win.

"Okay, then I'm really going to learn from you."

After saying that, he walked towards the fourth floor.

But as soon as he reached the fourth floor, Zhuang Mohan was stunned.

Because in front of him was a chess game with the entire floor as the chessboard.

The chess pieces above, each one as big as a human head, looked quite heavy.

Zhuang Mohan turned to look at Lu Xiao: "Are you trying to embarrass me?"

Even if he risked his life, he wouldn't be able to move many of these large chess pieces.

Lu Xiao smiled and said, "Of course, you don't have to do it yourself, sir. Look over there."

He pointed to an empty space at the back, where there was a platform. On the platform, there was also a chessboard, but it was a normal-sized one. However, the chessboard didn't have chess pieces on it, but instead was lit with two lights, one black and one white.

Zhuang Mohan was puzzled.

Lu Xiao explained, "This building also has a mechanism. You stand there and tap where you want to place the piece. The mechanism inside the building will do the rest for you."

Zhuang Mohan had never tried this novel way of playing before, so he walked forward curiously.

I stared at the chessboard emitting black and white light for a long time, but I couldn't figure out how it was done.

Then he asked, "Am I playing black? Or am I playing white?"

Generally speaking, in Zhenlong, the positions of black and white are fixed.

However, Lu Xiao said, "It's all fine. You can choose whichever you like. The chessboard facing you is currently playing white. If you want to play black, just turn the board around. Also, in this game of Zhenlong, no matter which side you play, you make the first move."

Good guy.

This is a bit disrespectful.

Doesn't that mean that at least one of the two parties, black or white, is giving up the piece?

For a true chess master, even giving up just one piece can have an unimaginable impact on the outcome.

But considering the methods Lu Xiao had demonstrated during the previous three levels, Zhuang Mohan didn't say much.

Then he lightly clicked on a certain position on the chessboard.

The next moment, a ball of white light lit up where he clicked.

At the same time, a hole appeared in the sky above the corresponding position on the chessboard inside the building, and a white piece fell from it, landing steadily on the ground.

At this time, Zhuang Mohan looked at Lu Xiao curiously.

He can't play chess alone.

But Lu Xiao just stood there, not moving at all.

Just as Zhuang Mohan was about to ask a question, a black light suddenly lit up from a certain spot on the chessboard in front of him.

Zhuang Mohan was stunned: "What a brilliant move!"

At this moment, he also understood that this round of Zhenlong, like the third level of Qinyin, was also automatic.

He couldn't help but glance at Lu Xiao and asked, "Why are you so lazy?"

Lu Xiao laughed and said, "It's not that I'm lazy, but I can't stay in the Ascension Pavilion forever, so this is the only solution I can come up with."

Zhuang Mohan thought about it for a moment, felt it made sense, and said nothing more.

Then he threw himself into the chess game in public.

At the beginning, he played very easily

When he made a move, the chessboard in the building also made a move.

When a chess piece is captured, the corresponding chess piece in the upper chessboard will also be taken back.

In a short period of time, the fight between the black and white pieces was hard to decide.

However, as time passed, Zhuang Mohan's expression gradually became serious.

His moves became slower and slower each time.

In the end, it might even take dozens of breaths before a move is made.

In this way, time passed little by little, and when the last black dot lit up.

Zhuang Mohan finally sighed and said, "Alas, I still lose."

At this point, the situation on the chessboard was clear: the last black piece had directly slain the white dragon.

Even a person who knows a little about chess can see that this game is hopeless.

Zhuang Mohan not only lost, but also lost miserably.

But he was very dissatisfied.

He immediately turned the chessboard around, intending to play another game.

When the chessboard is turned, the chess pieces that were dropped later disappear instantly, and the chess game is restored to its original state.

Afterwards, Zhuang Mohan, playing with black, made a move, repeating the previous scene.

When the last white piece fell, the black dragon was slaughtered again.

The defeat was also inevitable.

At this moment, Zhuang Mohan stared blankly at the chessboard in front of him, not saying a word for a long time.

He really couldn't understand why the result was the same even though the positions had been changed.

Is this still considered Zhenlong?

Why does this kind of "Zhenlong" exist in the world?

After a long while, he looked up and said to Lu Xiao, "2.5."

"If your chess skills are as unmatched as mine just now, then the title of the world's number one chess master can be exchanged for a lot of money."

Lu Xiao laughed and said, "I should be better than your non-existent opponent. After all, the mechanical chess game is a bit rigid and lacks some spirituality."

Zhuang Mohan asked, "Is this still rigid?"

He had just been badly abused.

"Hmph, no more, no more, let's go to the fifth floor and take a look."

Zhuang Mohan said this unhappily, then walked down the platform and headed towards the fifth floor.

Lu Xiao smiled slightly, then followed him up to the fifth floor.

The fifth floor looks a bit ordinary.

There was only one table in the middle.

There was a pile of white paper on the table, and next to it were pens and ink.

This level seems to be about writing something.

Zhuang Mohan looked around curiously, but didn't find the question.

So he looked at Lu Xiao..

Chapter 249 Shocked Zhuang Mohan

Seeing the confusion in Zhuang Mohan's eyes, Lu Xiao certainly understood what he was thinking.

Then he pointed to the chair in front of the table and said, "Sit over there, and the questions will appear."

After hearing this, Zhuang Mohan immediately walked forward.

The moment he sat on the chair, a light curtain lit up in the air opposite him.

Then, lines of text appeared on the screen.

"Prove that any even number greater than two can be decomposed into the sum of two prime numbers."

annotation:

More than two: something that is greater than two.

Prime number: A number that has no factors other than one and itself.

Supplementary Articles:

Four is two plus two (two is a prime number).

Six is ​​three plus three (three is a prime number).

Eight is three plus five (three and five are both prime numbers).

Zhuang Mohan had become immune to this kind of mysterious trick by now, so he wasn't too surprised.

Then he stared at the question for a long time before he understood what the question was.

But after he understood it, he became even more confused.

After a long while, he turned around and asked Lu Xiao.

"This group of Yiling stewards are trying to figure out the magic of numbers?"

Lu Xiao nodded. "2I Weeping Pipe, One Umbrella, Two Er, Not bad, sir, would you like to try it? This problem is not easy."

After hearing this, Zhuang Mohan became interested again.

Then he said confidently, "Okay, then I'll give it a try. I do have some experience with numerology."

After saying this, he returned to the question and fell into deep thought.

After a moment, he picked up a pen and paper and began to calculate.

Unfortunately, before he could calculate for long, his movements froze.

Then he shook his head and said, "No, no, there's something wrong with this idea."

As he spoke, he crumpled up the piece of paper he had just written on, threw it away, and started over with a new piece of paper.

Gradually, more and more paper balls were piled up on the ground.

Zhuang Mohan's frown deepened.

By the end, he was even pulling at his hair.

Lu Xiao had anticipated this scenario.

The question is: Any even number greater than two can be decomposed into the sum of two prime numbers.

Does it look familiar to everyone?

I guess someone already knows what this is about.

Translated, this question is: Any even number greater than two can be written as the sum of two prime numbers.

That's right, this is one of the three major conjectures of modern mathematics in Lu Xiao's previous life, the Goldbach conjecture.

There's no way Zhuang Mohan could solve this kind of worldly problem, the "9th Moon" chair puzzle.

After a long time, and after pulling out countless hairs, he finally gave up.

He turned and looked at Lu Xiao with a look of resentment: "Is this a question that a human could come up with?"

He was anxious.

Lu Xiao smiled and replied, "Don't worry, sir. To be honest, this question wasn't what I was thinking of, and I can't solve it."

After hearing this, Zhuang Mohan felt much better.

This was the first time he heard Lu Xiao say "no".

If Lu Xiao could even solve such an absurd problem, then he would really think that he was omnipotent.

Then Zhuang Mohan put the pen on the table and said.

"I don't understand. I'm old, and I've already spent a lot of energy playing two games of Go. If I continue solving it, it will definitely shorten my life. I'll leave this problem to the next generation."

After saying this, he asked Lu Xiao again.
