The rest of the time, Lin Yun'er spent the unhappiness, she didn't go to her room to rest but sat on the sofa in the living room to watch TV, but Lin Yun'er was speechless, she just turned on the TV a little bit of sound, and her father immediately rushed over and minimized the sound of the TV.

What's even more unbearable is that his father's attitude towards that Li Yuzhe guy is called a courteous one, I don't know if I still think that my father is the slave of the other party, Lin Yun'er took a bite of the apple in her hand, and her little brows were furrowed.

At about 17:30, the madman Li Yuzhe finally walked out of his room, and his father immediately posted it and put on a flattering smile, and then Li Yuzhe gave his father a few stock numbers, and his father who got the number was about to kowtow to the other party to thank him.

This is a liar, the scene at this time made Lin Yun'er's impression of Li Yuzhe stay on the word liar, if it wasn't a liar, how could his father be like a demon, well, just wait for his grandfather to come back.

Soon Li Yuzhe also walked to the living room and wanted to watch TV with Lin Yun'er, but when he saw Li Yuzhe coming over, Lin Yun'er immediately lay on the sofa and stared at Li Yuzhe fiercely: "What are you doing, this is all my territory." ”

"Huh!" Looking at the innocent girl he liked very much in his previous life, Li Yuzhe suddenly laughed.

Seeing Li Yuzhe smiling at herself, Lin Yun'er was speechless and said, "What are you laughing at, big liar." ”

As soon as he finished speaking, Lin Zhecheng, who had just returned to the room, immediately came out and complained to Lin Yun'er: "Ah Yun'er, get up quickly, look at what you look like lying on the sofa, there is no politeness at all, hurry up and let Uncle Yuzhe sit." ”

"Why Dad, this is the first time I grabbed it, I'm going to lie down, no one cares." Lin Yun'er, who had long been unhappy with Li Yuzhe, shouted loudly.

Looking at Lin Yun'er who was cheating, Lin Zhecheng didn't know how to deal with this little guy for a while, and looked at Lin Yun'er lying on the sofa desperately, Lin Zhecheng said to Li Yuzhe in embarrassment: "It's all what I'm used to." ”

Li Yuzhe also laughed at the right time, to be honest, he felt that Lin Yun'er was really cute, although the innocent Lin Yun'er was very good-looking and beautiful, but if Li Yuzhe was asked to choose what he liked, he would prefer the quirky Lin Xiaolu children's shoes at this time.

"Big brother is fine, I'll just sit on the side and watch." Li Yuzhe smiled, and then sat down on the stool on the side.

And seeing Li Yuzhe on the stool, Lin Yun'er immediately turned around, looked at Li Yuzhe proudly and smiled, and this proud little appearance made Lin Zhecheng see it, Lin Zhecheng immediately pointed at Lin Yun'er and said: "Your grandfather is back, if you still dare to do this, see that your grandfather doesn't punish you, I think you want to do your grandfather's exercises again." ”

After speaking, Lin Yun'er's whole body trembled, her grandfather's exercises were the so-called math problems, the operations were many and difficult, as long as she did ten questions a day, Lin Yun'er would vomit, so when she heard that she was doing the exercises, Lin Yun'er was instinctively afraid, but soon Lin Yun'er calmed down, because according to her father's words, this guy named Li Yuzhe should be her grandfather's student, hehe, if this is the case, then Lin Yun'er is not afraid, you must know that her grandfather is famous for torturing students' evil professors, Lin Yun'er has self-confidence, If his grandfather chooses between his own granddaughter and his students, he believes and prefers it, and his own granddaughter has an absolute advantage.

Looking at Li Yuzhe, who was sitting on a stool watching TV and giggling, Lin Yun'er muttered, "Wait a minute, see if you still laugh or not." ”

It was about 18 o'clock when Lin Wanxi finally walked into the house.

Seeing that the door of her house was opened, Lin Yun'er immediately jumped up from the sofa and rushed to the door, shouting coquettishly as she rushed: "Grandpa, I miss you." ”

Seeing Lin Yun'er rushing in front of him, Lin Wanxi was also very happy, this nine-year-old had no mother (not dead, don't say that I wrote Yun'er's mother to death!) Lin Wanxi, who also likes his granddaughter, immediately hugged Lin Yun'er in his arms and smiled happily: "Why did my family Yunbao come back today, it's really good, I asked your father to cook a lot of good dishes today, and you must eat a lot later." ”

"Well, grandpa is the best!" Lin Yun'er said sweetly.

"Haha, you are my good granddaughter, grandpa is not good to you, who is good to you?" Then the two came to the living room, at this time Li Yuzhe was already standing in the living room waiting, seeing Lin Wanxi, Li Yuzhe immediately bowed ninety degrees and said, "Teacher." ”

As soon as he saw Li Yuzhe, Lin Wanxi immediately said more happily: "Yuzhe, you came so early, oops, you should have informed me earlier, then I won't let you wait." After speaking, he immediately took Li Yuzhe's hand and said, "Come, come, come, come into my study with me, I have something important to ask you for." ”

Then he pulled Li Yuzhe to the study, and Lin Yun'er on the side became anxious: "Hey, grandpa, your granddaughter finally came back, you don't accompany your granddaughter for a while, I'm your own granddaughter." ”

Regarding Lin Yun'er's words, Lin Wanxi didn't hear a word at this time, pulled Li Yuzhe into the study, and then closed the study door with a 'bang', almost hitting Lin Yun'er's nose.

This made Lin Yun'er's nose not hit, but he was angry, looking at Lin Yun'er who was blocked out of the study, Lin Zhecheng quietly appeared beside Lin Yun'er at this time and said: "Ya girl, forget it, don't want to fight with Yu Zhe, you can't fight him, your grandfather likes him tightly, Yu Zhe helped your grandfather complete his lifelong dream and won the banner of the first mathematics department in South Korea, and Yu Zhe is a super genius, hehe girl, do you know what a super genius is, that is!" ”

It's just that Lin Zhecheng hasn't finished speaking, Lin Yun'er on the side wrinkled his little nose and said: "I know what Lao Lin is a super genius in your mouth, but I can tell you now, if you talk by my side again, I will go and tell my grandfather, Lao Lin, you took 40 million from your grandfather to speculate in stocks and then lost all of it." ”

"Huh!" Lin Zhecheng immediately softened, and then looked at Lin Yun'er and begged for mercy: "Okay, okay, I won't say it, I won't say it, I still want to stir-fry." ”

After speaking, Lin Zhecheng returned to the kitchen with hatred, but after a while, Lin Zhecheng was happy again, because he thought of the few stocks that Li Yuzhe gave him, and told him that as long as he pursued for two months, he would be able to get all the losses back, and then he would make tens of millions, Lin Zhecheng couldn't wait.

So looking at Lin Yun'er, Lin Zhecheng said to himself: "After two months, I won't be coerced by you." ”

What are Lin Wanxi and Lee Woo-cheol doing in the study, it turns out that Lin Man-seok's Seoul college students formed a team to overcome the 50s of the last century, and the Canadian mathematician Richard K. Guy put forward a number theory conjecture: for a given prime number p, f(p)=(p-1)+1 can be true. A prime number, on the other hand, is a number that is not divisible by a natural number greater than 1 except for 1 and the integer itself. ”

Many mathematicians have previously demonstrated that this formula is true in prime numbers before 300 million.

At first, it was still very smooth, but during this time, the overcoming group stagnated, because it seemed that this formula could no longer be overcome, so that the overcoming team fell into despair, although Lin Wanxi was a bad professor in the mouth of the students, but in fact, he really liked and protected his students, watching the students who spent a year forgetting to sleep and eat fell into despair, to say that it is false not to feel distressed, so Lin Wanxi thought of Li Yuzhe, his super genius student.

So he brought Lee Woo-chul in the hope that he could take those of his students out of the swamp of despair.

However, Lee Woo-cheol did not disappoint Lin Man-seok, he used the data of the previous Seoul big attack group to use the set theory operation, analysis, optimization, etc. many times in more than an hour, combined with the experiment of Mathematics7, and finally found that when p=353942783, the formula is not valid, so he used a counterexample to demonstrate this ancient conjecture.

This result once again stunned Lin Wanxi on the spot!
