Li Yuzhe and Li Zhien held hands together, talking and laughing and preparing to take the subway home, but when they passed by Jiang Hudong's barbecue restaurant, the fragrance that instantly came out of it made Li Zhien swallow a mouthful of saliva involuntarily and said: "Wow, it's so fragrant." Pen Fun Pavilion www.biquge.info"

After listening to Li Ji-eun's words, Li Yuzhe knew that because of himself, Li Ji-eun had not eaten meat for a long time, and basically Li Ji-eun's money bought him the kind of nutritious meal that was very expensive like batter, looking at Li Ji-eun's way of swallowing saliva, Li Yuzhe was distressed and immediately touched his pocket, but Li Yuzhe helplessly found that there was only 5,000 won left in his pocket for the journey home.

This made Li Yuzhe look at Li Zhien very frustrated and said: "I'm sorry Enbao, OPPA doesn't have money yet, so I can't let you eat meat yet, but please believe in OPPA, within a year, OPPA will make you want to have what you want? That is, if you want the stars in the sky, OPPA will also help you do it." ”

Li Yuzhe's words moved Li Zhien and said: "I don't want anything, I just need OPPA, as long as OPPA can stay by my side forever, it's enough." ”

With a smile, holding Li Zhien tightly in his arms, Li Yuzhe smiled and said, "Don't worry, I promise that I will always be by your side." ”

The road to the sky, to Li Yuzhe's surprise, just when Li Zhien and Li Yuzhe were about to walk to the subway station, they suddenly found that a business was doing an activity, the content of the activity was a math problem, the topic was:

Find this 10-digit number

Request:

1. Have a detailed answer

2. Don't use some theorems that exceed the second year of junior high school!

This problem stumped a group of people at once, but because the merchant proposed that as long as he could solve this problem, he would not only give 500,000 won in cash, but also a high-end Hanbeef gift box.

Two attractive prizes, so that the merchant is still surrounded by a group of passers-by, among which there are a lot of college students and elites of various professions, this question is actually easy to be solved in their hands, but it is very helpless that the merchant is very bad at adding some theorems that cannot be used more than the second grade of junior high school, which will stump many masters, because most of them have learned the second theorem of junior high school has long been returned to the teacher.

And let a junior high school student do this problem, for the third grade of junior high school students this problem is too difficult, unless you are a math genius, otherwise this Olympiad problem, ordinary junior high school students you can't solve, even you can't understand.

Li Ji-eun, who is now in the third grade of junior high school, shook his head speechlessly and said to Li Yuzhe: "omo, oppa, I don't understand this question, who can solve it, it's too difficult, 500,000 won and that high-end Hanniu suit is really not easy to get." ”

Listening to Li Zhien's words, Li Yuzhe's mind was full of numbers at this time, and Li Yuzhe felt very simple about this Olympiad math problem that was very difficult in Li Zhien's opinion, and in less than two minutes, the answer was completely displayed in his mind in 3D mode.

At this time, the host's disappointed shout came from the stage: "Oh, this gentleman is wrong, it's a pity, this problem is only the Olympiad of junior high school, is there really no one who can solve it?

The host's words made all the audience speechless, and they were inexplicably said that they were not talents, which made the audience very unhappy, but they were helpless, because what the other party said was right, that is, a junior high school Olympiad problem, and he really couldn't do it. Shaking his head helplessly, passers-by were all closed in their hearts, hoping that someone could solve the problem and kill the host's arrogance.

However, it's a pity that the host didn't even shout three times and still didn't come on the stage, and the host of the shopping mall on the stage shook his head with a wicked smile and pretended to be speechless: "There are still ten minutes left, if you haven't been on stage, this event, it's a pity that I'm going to announce the end." ”

Just when the host announced that the event was about to end, Li Yuzhe smiled and said to Li Ji-eun at this time: "Enbao, do you want to eat high-grade Korean beef at night?"

Regarding Li Yuzhe's words, Li Zhien subconsciously nodded and said, "Of course I think about it, but that topic is really too difficult." ”

As soon as he finished speaking, Li Yuzhe laughed and walked to the stage: "It's not difficult, watch oppa let Enbao eat Korean beef at night." ”

"oppa!" Seeing Li Yuzhe on stage, Li Zhien was worried, because she knew that her OPPA should never be that question, because he had been in a coma for four years, and now he has only been awake for a month.

Walking to the stage, at this time, the host saw someone coming up, and immediately rejoiced: "OK, we in the Republic of Korea finally have 'talents' come up, but I don't want to wait and watch 'talents' go down lonely." ”

Walking up to Li Yuzhe, the host took the microphone and said to Li Yuzhe: "Hello, 'talent', I want to ask your name." ”

"Li Yuzhe!"

"Ah, it's Mr. Li Yuzhe, then I want to ask what your occupation and education are?"

"I am unemployed, and my education is that I did not graduate from junior high school. ”

After Li Yuzhe finished speaking, the audience immediately burst into laughter, and the host on the stage also immediately smiled and said: "Li Yuzhe, don't make trouble, although this is a light activity, but you can't come up and be funny, do you know how many college students' 'talents' have fallen into the sand just now? Okay, Li Yuzhe, I will give you a souvenir, let's go down." ”

The host's words caused the audience to laugh, and Li Ji-eun watched Li Yuzhe tighten his little fist very worriedly.

But to the host's surprise, after listening to his mocking words, the young man in front of him only smiled slightly, and then looked at himself very calmly and said: "There are rules for your activities, and you will not be allowed to participate if you have a high school or university degree? If so, I will step down immediately, if not, why don't you dare to let me try, are you afraid that the prizes in your shopping mall will be won by me?"

After Li Yuzhe finished speaking, the host was dumbfounded, and someone in the audience immediately began to help Li Yuzhe coax: "Don't you dare, I'm afraid that he will win your prizes, and your shopping mall is too stingy." ”

If there is one, there is a second.

"Oh, do you want to hold an event in the mall, and after a while, no one will come up, and now people come up and don't dare to let people answer the question, what is the broken mall. ”

"That's it, close the door early!"

It didn't matter, and immediately a crowd of people began to laugh and shout: "Close the door, close the door!"

The voice was so loud that almost half of the East Gate could hear it, and the manager of the horrified shopping mall immediately came out to apologize to everyone, and then repeatedly said that it was the host's joke, and Li Yuzhe could solve the problem at any time.

After apologizing, the manager also immediately glared at the host, and the scene just now also frightened the host, he just wanted to tease the young man, but he didn't expect the other party to immediately fight back, unusually sharp, and also instigated the crowd at the scene, becoming the person who spoke for him, this alone, the host knew that the young man in front of him may not be a good stubble.

"I'm sorry Mr. Li Yuzhe, I made a very inappropriate joke just now, please don't mind, now please solve the problem. The host is also a master who can bend and stretch, and after speaking, he handed a pen to Park Ji-ho.

took the pen, Li Yuzhe said thank you very politely, which made the host nod in his heart, as if the other party was still more polite, and he may have been too much just now.

When Li Yuzhe slowly walked to the front of the board, I don't know why everyone at the scene secretly began to sweat for Li Yuzhe, and before he knew it, everyone in the audience was already on Li Yuzhe's side, hoping that Li Yuzhe could successfully solve the problem, and hoped that Li Yuzhe could get the prize.

Seeing that Li Yuzhe suddenly broke out with a strong cheering sound from the audience, this scene was still something that the host had not encountered, which made the host very puzzled, what did Li Yuzhe do to make so many people cheer for him, you must know that these people were still cursing the people who came on stage just now for not being able to do the question, and then laughing at them.

In fact, what the host didn't know was that Li Yuzhe just used a very simple method to separate the business from himself and become an opposite, so that the crowd that was not a business would of course immediately join Li Yuzhe's side.

Just when everyone was sweating for Li Yuzhe, Li Yuzhe began to write hard!

After writing the last 0, Li Yuzhe threw the pen, and the host looked at the number exactly the same as the answer in his hand in surprise, and said dumbfounded: "It's completely correct." ”

As soon as I finished speaking!

"Ahh

Chapter 7: I Am a Genius

"oppa, why are you so smart, are you a genius?" walked out of the subway entrance, Li Zhien was completely excited, looking at Li Yuzhe with adoring eyes almost like a god, the cheers of hundreds of people just now seemed to be still in his ears, his oppa actually solved the problem that so many people couldn't solve by dividing five by two, you must know that Li Zhien in the third year of junior high school couldn't understand it, so looking at Li Yuzhe at this time, Li Zhien was very excited.

Looking at Li Ji-eun, who was looking at him with adoring eyes, Li Yuzhe proudly picked up the Hansang gift box in his hand and shook it and said, "Of course, your OPPA is a genius, and in the future, your OPPA will definitely let you eat Hangyu every day." ”

Li Yuzhe's words made Li Zhien smile happily and said, "Oppa, do you want me to become fat?"

"Fat is fat, how cute chubby is so cute. ”

"No, I don't want to be fat. ”

"Then just eat and don't get fat. ”

Lee Woo-cheol's words made Lee Ji-eun laugh happily!

When he got home, Li Yuzhe asked Li Ji-eun to take out the portable gas stove, then put on the frying pan, opened the Hanwoo gift box, and then took out the high-grade Hanniu inside, you must know that this is the A+++ introduced on TVSpecial-class Korean beef, such a gift box can be divided into 800,000 won, 1 million won, 2 million won, etc., the gift box of Hanniu won by Lee Woo-cheol is 1 million won, as soon as it is taken out, the snowflake-like meat makes Lee Ji-eun sigh and swallow a mouthful of saliva unconsciously.

Cut the Korean beef into slices and thin slices, so that it will be cooked faster, put some oil in the pan, wait for the oil to be hot, immediately put the Korean beef slices into the pot, and soon the beautiful sound and enticing aroma of the Korean beef will waft out of the pot.

"It's so fragrant, oppa!" Smelling the fragrance of Korean beef, Lee Ji-eun immediately looked at Lee Woo-cheol with surprise eyes.

Li Yuzhe looked at Li Zhien and smiled: "Okay, let's eat it." After saying that, he picked up a piece of Korean beef bun and fed it to Lee Ji-eun's little mouth, and ate the lettuce bun in one bite, and Lee Ji-eun immediately sighed: "Omooppa, it's so delicious." ”

Looking at Lee Ji Eun's happy appearance, Li Yuzhe also laughed happily, in the next time to eat Hangyu together, what Li Ji-eun didn't know was that Lee Yu-cheol had been eating lettuce leaves, and he was very clever to make Lee Ji-eun think that he had been eating Hang-eun, watching Lee Ji-eun eat very happily, although Lee Yu-cheol didn't eat a piece of Hangyu-cheol, but as long as Lee Yu-cheol saw Lee Ji-eun's happy appearance, it was enough, it was enough

There was nothing to say all night, and the next day, Lee Ji-eun was ready to go to the company to practice, and during this time, Lee Ji-eun was invited by Cheng Shijing to sing the song "It's You" with him. Lee Ji-eun practiced very hard, but only Lee Yu-cheol knew that it didn't work!

After Li Zhien left home, Li Yuzhe also got up, first cleaned the house, and when the house was clean, Li Yuzhe was ready to start studying, and took out the high school textbook sent by the owner of the second-hand bookstore last night, Li Yuzhe first took out the mathematics of the first year of high school, and began to read it seriously!

But after watching it for less than 10 minutes, Li Yuzhe suddenly found that he seemed to have memorized all the mathematics of the first year of high school, which made Li Yuzhe shocked, you must know that he didn't have this ability before, but now looking at this mathematics of the first year of high school, it is as simple as looking at the number of elementary school plus one.

Even Li Yuzhe himself can't understand why, but he understands everything, a complex math problem, in less than a minute, those answers and the process of solving the problem appear in his mind in three dimensions, and he doesn't even have to think about it.

And his memory is also terrifying, as long as he reads the book, he can basically remember it, is this unforgettable, Li Yuzhe was very surprised by his ability at this time.

In order to confirm whether he has become unforgettable, Li Yuzhe read all the books from the first year of high school to the university in one go, and what made Li Yuzhe unbelievable was that it only took half a day for Li Yuzhe to remember the knowledge that ordinary humans would take several years to learn.

Feeling that knowledge was constantly being digested in his mind, Li Yuzhe smiled excitedly and said, "This is what it feels like to be a genius?"

Sitting on the bed, Li Yuzhe began to think about how his high IQ came about, and later after Li Yuzhe's own repeated thinking, Li Yuzhe thought that his rebirth must have intensified the activity of this body brain, and when he tried to occupy this body, the potential of the body owner Li Yuzhe's brain was also stimulated, and he accepted the memory of his own soul, plus his own soul fused the soul of his own master, so Li Yuzhe's strength and speed were twice that of ordinary people.

"Am I a genius now?" Li Yuzhe shook his fist and suddenly laughed excitedly, how envious he was of geniuses before, I don't know why geniuses are smarter than themselves, how those people were admitted to college, and now Li Yuzhe finally knows why, because there are many things, geniuses don't need to learn, those naturally appear in the mind of geniuses, unlike their previous self, no matter what, they can't learn and can't understand.

Feeling the crazy feeling of becoming a genius, Li Yuzhe smiled, this kind of problem that was discovered by others earlier was really good, and suddenly Li Yuzhe, who was sitting on the bed, finally thought of a way to get a sum of money quickly.

Thinking of this, Li Yuzhe laughed

South Korea is a country that allows casinos to exist, but the casinos set up in this country only allow foreigners to gamble inside, and locals will be severely punished if they go in to gamble. There are a total of 17 in Korea, 16 of which are only allowed to foreigners, and only 1 is open to locals. 3 in Seoul, 2 in Busan, 1 in Incheon, 2 in Gangwon, 1 in Daegu, and 8 in Jeju Island.

At 12 o'clock in the afternoon, Li Yuzhe appeared in South Korea's Qile Casino, you must know that Qile Casino is a casino that only allows foreigners, and how did Li Yuzhe get in?

"Big brother, where are you, I'm from Jiangcheng, and I'm here to travel to South Korea, so I'll come to this casino to play twice. Li Yuzhe used fluent Chinese to mingle behind a veteran who often came to Qile Casino, and the staff of the casino originally wanted to check Li Yuzhe's passport, but then a manager's staff shook his head and said no, because he could understand Chinese, so fluent Chinese, except for the Celestial Empire, few Koreans can speak so fluently.

It's just that the manager couldn't have imagined that Li Yuzhe was a person who was reborn from the Celestial Empire.

And the uncle of the Celestial Dynasty who was picked up by Li Yuzhe was also very happy to meet a little fellow in the Seven Luck Casino, not only immediately had a friendly conversation, but also told Li Yuzhe some casino tips, completely treating Li Yuzhe as a fellow countryman in his own country.

Chapter 8 Change of residence

Walking with the uncle of the Celestial Empire, the uncle is a native of Xingzhou of the Celestial Empire, very close to Li Yuzhe's Jiangcheng, the uncle's name is Chen Zhaosheng, he came to South Korea to do small business, and he likes to play two so he comes to the casino from time to time to play.

Under the leadership of Uncle Chen, Li Yuzhe took out yesterday's check for 500,000 won, originally Li Yuzhe wanted to hand over this 500,000 yuan to Li Zhien for safekeeping, but Li Zhi-eun said that he didn't want anything, saying that he didn't need much money in the company, but Li Yuzhe was at home, and if something happened, he could still have an emergency if he had money.

For this sister who puts herself first at all times, Li Yuzhe really doesn't know what to say.

Swapping the check for 500,000 won for chips, Uncle Chen on the side smiled and said, "How about it, Xiao Li watched me play twice first." ”

Li Yuzhe immediately smiled and nodded and followed Uncle Chen, and then the two came to a table where he played at 21 o'clock, Li Yuzhe's previous life Li Yu was a small otaku, so he didn't have much interest in gambling money, and he didn't even gamble money, so he never went to the casino, so he first followed Uncle Chen to see how he gambled money.

Blackjack is a popular and traditional gambling game in the West, also known as "blackjack", which is a way of gambling by counting points to win or lose.

However, 21 has a fatal weakness, of course, for ordinary people, that is not a weakness at all, but for some geniuses, 21 can use the statistical characteristics of mathematics and good memory to master the control most effectively due to the limited number of cards played each time, in order to achieve continuous victories and defeat the dealer.

Coincidentally, this year there is an American movie "21 Points", which tells the story of several math geniuses who use their wits to wreak havoc in Las Vegas, and this film is adapted from Ben Mozridge's 2002 novel "The Capture of Las Vegas". However, it is important to know that this novel is inspired by a true story, and its protagonist is Kaiwen Ma, who is of Chinese descent. In 1994, Ma Kaiwen, who was in his third year at the Massachusetts Institute of Technology in the United States, originally planned to enter medical school after graduation to continue his studies, but was invited by a friend by chance (to be continued).
