Li Hua'an's old face turned red and shifted his gaze to the leech.

Li Huaan slowly, put the small flame on the leech, only to hear the sound of "snort~", the leech immediately loosened its mouth as soon as it hurt, and the whole body fell down.

Coincidentally, the leech fell into Hua Ningxue's belly pocket......

Afraid that the leech would not die and cause a second injury to Hua Ningxue, Li Huaan didn't think about it, and immediately put his hand into Hua Ningxue's belly pocket......

The first time I reached in, I didn't even touch the leech...... Rather, I touched it......

Li Hua'an's nosebleed came out, and after a while, Li Hua'an grabbed the leech and threw it into the fire.

Seeing that the leech was caught, Hua Ningxue immediately put on her clothes and slapped Li Huaan.

Before Li Huaan could react, Hua Ningxue had already hugged her legs, sat on the ground and cried.

Li Huaan realized now that he was too much......

Li Huaan wiped his nosebleed and comforted Hua Ningxue: "This ...... I'm sorry, I didn't mean to......"

After Li Huaan finished speaking, Hua Ningxue raised her head and looked at Li Huaan and slapped her again.

"Forget it before, you're too much this time!"

"Where are you touching my hands, and my innocence is ruined in your hands!"

"I hate you......"

After roaring, Hua Ningxue continued to cry again.

Now Li Huaan knows it thoroughly, it turns out that this is the bottom line of Hua Ningxue.

The kiss was also counted as saving her face before, so she didn't turn her face, but this time it was too much.

If this matter spreads, Hua Ningxue will definitely not be able to get married, and she may be chopped into potato chips by her father.

Looking at the heartbroken Hua Ningxue, Li Huaan really didn't know how to comfort him, after all, Li Huaan patronized writing and had never had a girlfriend, so it was really embarrassing for him to coax girls.

Li Huaan had no choice but to slap himself, looked at Hua Ningxue and said, "Then~ Then you can beat me until you are happy!"

Although this slap was very loud, Hua Ningxue even raised her head, lowered her head and cried and choked:

"Beat you, can I get me clean of the way by beating you?"

"Don't talk to me, I don't want to pay attention to you. ”

"I ~hate~ you!"

After speaking, Hua Ningxue continued to cry again.

Now Li Huaan is completely helpless, Hua Ningxue is right, innocent such a thing, how can it not be repaid.

But there is also a way, since Hua Ningxue can't get married, why don't you just marry her yourself? Not to mention that the parents are so beautiful and have a good figure.

Thinking of this, Li Huaan began to reflect.

Although I have a good impression of Hua Ningxue, after all, who can not love such a cute girl?

But Li Huaan's love still stayed on Murong Wuxi.

Compared with Hua Ningxue, I still prefer Murong Wuxi, although I am not very familiar with her, and I haven't even said anything, but I still think of her inexplicably in my heart.

No matter who he chooses, Li Huaan remembered again, a very important logical question.

If I marry a wife here, will time and space be disordered?

If you stay here, won't you be no longer there after a thousand years? Will that cause a series of butterfly effects?

If you find an opportunity to go back to modern times in the future, won't you be able to take everything you have here, including your beloved, with you?

The more he thought about it, the more his head hurt, Li Huaan patted his head and looked at Hua Ningxue beside him.

A scene that surprised Li Huaan happened.

Hua Ningxue actually cried and cried and fell asleep!

Looking at Hua Ningxue lying on the ground, sleeping soundly, the tears in the corners of her eyes haven't dried yet......

I have to say that the heart is really big......

Li Huaan took down the clothes on the shelf, and when they were almost dry, Li Huaan put the clothes on Hua Ningxue.

After covering it, he gently wiped the tears from the corners of Hua Ningxue's eyes.

Looking at the sleeping Hua Ningxue in front of him, it's really easy to make people think about it......

In case Hua Ningxue caught a cold, Li Huaan added some firewood to keep the surrounding temperature at a temperature, so that Hua Ningxue could sleep more comfortably.

Although at this time, Li Huaan was already exhausted, but the surrounding environment should not be taken lightly, and one had to be left to guard.

Li Hua'an pulled out the dragon scales and stabbed it into the soil beside Hua Ningxue, in case of any danger, she could also defend against the enemy.

I went to the stone gate in front of me to see what was going on.

He took a torch from the fire and walked towards the stone wall in front of him.

There are also many candlesticks hanging above both sides of the stone wall, and it seems that some people are really doing it wantonly.

The closer he got to the stone wall, the more uneasy Li Hua'an's heart became, because Li Hua'an vaguely saw that there seemed to be some graphics on the stone wall......

And it doesn't look like the way those figures are arranged like they are in this era.

When he walked into the stone wall and saw those graphics clearly, Li Huaan's heart exploded all of a sudden.

When the torches illuminated the center of the stone wall, a large rectangle composed of forty-nine small rectangles appeared in front of Li Hua'an's eyes.

But this is not the most terrifying, what I saw next was the fear that directly hit Li Hua's peace of mind.

As shown in the picture on the right, there are 49 small rectangles in the large rectangle, please divide it into the most six pieces, recombine them into a large rectangle and make the small rectangle inside into 48 pieces (one rectangle in the dashed line is not allowed to change the line or overlap with a pen). ”

This is still written in modern Chinese characters!!

Li Hua'an, who was so frightened, almost fell to his knees that this was a thousand years ago before the unified use of modern Chinese characters!

And it's such a difficult math problem! This! This ...... It's unbelievable!

On the stone wall in front of him, the content engraved in Chinese characters, I couldn't help but look at Li Hua'an is in a cold sweat.

Li Huaan rubbed his eyes, couldn't believe the scene in front of him, and continued to watch with a torch.

"When the problem is solved, the day the door is opened. ”

Underneath that word, there is also the large rectangular diagram, which, if you look closely, is made up of forty-nine small rectangular diagrams.

According to modern thinking, this large rectangular diagram should be cut apart and reassembled into a large rectangular diagram.

However, there is another requirement, that is, the composition of the new rectangular diagram must be reduced from the original 49 small rectangles to a large rectangle of 48 small rectangles.

Although the stone wall did not say that there were a few chances to try, or that there was any punishment for failure, Li Huaan didn't want to touch it yet.

The amount of information is too large at this time, and Li Huaan is still a little unable to react for a while.

With the question of the slow wall, Li Huaan returned to the fire.

If it weren't for looking at the sleeping Hua Ningxue on the ground, Li Huaan really didn't know what era he was in.

Looking at the surrounding environment, if you want to go out, open the stone wall, and it is estimated that there is no other way.

But what is there behind that stone wall that needs to be closed in this hellish place?

And look at the problems left on the wall, it can't be left by Hua Ningxue's generation, not to mention the math problem, just those words, no one can write it at the end of this year!

Li Hua'an's mind suddenly flashed, and a strange idea popped up!

I remember what Sherlock Holmes said: Eliminate all impossibilities, and the rest of the incredible is the truth.

Although Li Huaan knows that this truth may be a little unrealistic, now this is the only one that can explain these words.

That is, after dealing with yourself, there are modern people who have traveled back to ancient times!

And looking at the appearance of the stone wall, this traverser may be many years earlier than himself!

Thinking of this, Li Huaan didn't dare to think about it anymore. He was afraid that if he tried to go again, he would be completely paralyzed.

Now it doesn't matter why that person is setting the question, and it doesn't matter what is behind this door, when the door is opened, all problems will be solved.

As soon as he said it, Li Huaan picked up a branch and rewrote the title on the stone wall on the ground.

Looking at the modern math problems on the ground, Li Huaan even the importance of knowledge.

And the difficulty of this question, even if it is added to the college entrance examination, it is estimated that it can be a large number of students.

Normally, with Li Huaan's mathematical level, he should not be able to solve this problem, but for some reason, Li Huaan looked at this problem and seemed to have an answer in his mind.

"it!"

Li Huaan shouted, and suddenly remembered something!

Just the day before receiving the jade pendant, Li Huaan's mailbox received this question! And there are also solutions and answers to this question below!

At that time, I thought that it was a certain reader who was naughty and posted his own indiscriminately, but Li Huaan just glanced at it casually and didn't care.

I didn't expect it to be used here today!

Li Huaan clapped his hands, picked up the branch and wrote on the ground.

With Li Huaan's memory, write out the ideas and answers to the solution, and it is simply a pen!

Li Huaan was writing, and Hua Ningxue, who was lying next to him, was woken up by Li Huaan's shouting.

Although Hua Ningxue, who woke up, was still a little angry, she looked at Li Huaan's clothes on her body, and she was deflated again in an instant.

Anyway, I thought to myself, I never thought about getting married in my life, and I wandered the rivers and lakes all my life, so there was no need to be angry with Li Huaan.

Hua Ningxue got up, put her clothes on Li Hua'an's back, looked at Li Hua'an and asked, "What are you writing on the ground?"

"The hope of getting out. After speaking, Li Huaan continued to draw on the ground.

The crux of this problem lies in the "rectangle", the 49 small rectangles in the original picture show small squares, but the reassembled small rectangles and the large rectangles they form are not necessarily squares. ”

"So, we can cut the original picture into 5 parts, the top left picture is the cutting method, and by recombining, stitching into the shape of the top right picture, the original 7x7 large rectangle has been reorganized into a 7x (50/7) large rectangle"

"The small rectangles become 48, the total area of the large rectangle becomes larger (50), and the effective area remains the same (49) because there is a small 1x1 rectangle in the middle. ”

Problem solved!

Haha brothers, doesn't it look a little confused? The problem is not big, everyone just thinks that it is a difficult problem, and then the pig's foot solves the problem and opens the door, there is no need to study this problem, because I also went to Baidu to find this problem, with my IQ, I can't solve it, I copied it from Baidu......
