Lin Yi followed the elevator and it stopped at the twenty-second floor.

"I live on the 22nd floor. The next floor up is the leisure area of ​​Sunlight Blue Sea. Your two students can go up there and have fun later."

Mr. Gu got out of the elevator, walked to a room door, and opened the door: "Come in."

Inside the door, the room is very large and spacious, with one bedroom, one living room and one bathroom. You can see the street view and the twinkling city lights outside the floor-to-ceiling windows.

The ground is covered with a very thick mutton blanket, which gives you a very soft feeling when you step on it.

"Old Liu, it's really not me who's talking about you. If you weren't so stubborn, why are you always having trouble with yourself? Wouldn't it be great to go to Yanjing with me to become a professor?" Mr. Gu entered the room.

, went to make a pot of tea.

"Not to mention this, you also know the main purpose of coming this time." Old Liu shook his head.

"I know, I know, then you two, come over here first." Mr. Gu nodded and greeted Lin Yi and Liu Luran.

Later, Mr. Gu took out a stack of draft paper and two pens from his bag. Then he picked up the pen and sat at the table. After thinking for a while, he picked up the pen and quickly wrote three questions on the paper.

"I don't know how the two students you brought here are doing in mathematics yet. You should do this problem first, three questions." Mr. Gu gave the questions to Lin Yi and Liu Luran respectively.

Lin Yi took the question and glanced quickly.

"Honestly, I don't know what the Olympiad questions are. These three questions are written to judge your mathematical ability. If you can solve two questions, I will have a good chat with you about Olympiad problem solving.

It's a matter of thinking." Mr. Gu looked at the time and said, "I'll give you one and a half hours."

After finishing speaking, Mr. Gu walked towards Old Liu Tou: "Let the two of them write the questions there. It's been a long time since we two old guys have been able to play a good game. I'm all ready."

As Mr. Gu was talking, he was gearing up and took out a chess set from the cabinet.

"You, you, you were just not convinced when you lost to me before, right?" Seeing chess, Old Liu Tou was rarely happy.

"No, since I lost to you last time, I haven't had a good meal for several months. This time, I will definitely kill you and turn you upside down!" Mr. Gu vowed.

The two sat down and played chess.

Lin Yi held a pen in one hand and looked at the three questions in front of him.

The first question is about the use of trigonometric functions, the second question is about the structure of a sequence, and the third question is about the set structure of the probability methodology that combines inequalities and conic sections.

Three questions, from easy to difficult.

Lin Yi did not hesitate. After thinking for a moment, he picked up the pen and began to write and draw on the manuscript paper.

Liu Luran, who was sitting opposite Lin Yi, glanced at Lin Yi.

The difficulty of these three questions was not low. When seeing Lin Yi's serious expression on solving the questions, Liu Luran had to admit that she was still a little surprised.

In the previous set of mathematics questions in school, Lin Yi obtained high scores and then qualified for the Olympiad. This matter has always been a mystery in Liu Luran's heart.

She couldn't imagine why Lin Yi's math scores suddenly improved and he stood out from the crowd. Moreover, this time he was brought to Mr. Gu by Mr. Liu and became a dark horse.

But soon, Liu Luran abandoned the distracting thoughts in her head and began to immerse herself in solving the problem.

Over there, Mr. Gu and Mr. Liu Tou were drinking tea and playing chess, and they were inextricably killed.

Mr. Gu glanced at the two people sitting on the other side writing questions, lowered his voice, and looked at the chessboard: "I have never seen you bring a student to me before. Why did you make an exception this time?"

"It's rare to meet a good young talent, and I can help you as much as possible. I've been teaching all my life. When I got old and was about to retire, I realized that something was missing." Old Liu Tou picked up a horse and flew

Hit the cannon on the opposite side.

"It's really rare that there is a little guy who can become a good prospect in your opinion. If they are really so talented, why don't you give them to me? I can still speak in the Huaqing Mathematics Department.

, when the time comes, I will push my scores to let them in, or after passing the provincial Mathematical Olympiad, I will work harder and send them to the National Mathematical Olympiad to get a ranking, and then recruit them directly. How about?" Mr. Gu picked up a car and moved forward.

Eating a pawn.

"That depends on whether they are willing or not." Old Liu Tou shook his head slightly: "Their path is always their own choice. At most, I can only help the staff."

After speaking, Lao Liutou's horse took a step further and landed directly in front of the handsome man on the opposite side.

General, draw the car.

Mr. Gu's face became solemn for a while: "That won't work, I think, a good seedling should be treated like a good seedling, but you don't know whether it is a real seedling or a fake seedling. When it comes to mathematics, diligence determines the lower limit of achievements that can be achieved.

, talent determines the upper limit.”

"It's your turn. Don't think that I will make you regret your move if you look so serious. Come on, stop talking nonsense." Old Liu frowned and was unhappy.

"Oh, why are you so inhumane? We have been friends for many years and you won't give in even a single chess move." Mr. Gu was a little discouraged and abandoned his car to save Shuai.

Old Liu Tou took the opportunity and crossed the river with his pawn on the upper right.

"The pawn has no way out after crossing the river. I don't know how long I can survive. If I can capture one more of your chess pieces and win one more game of chess, that would be great." Old Liu Tou laughed.

Over there, Lin Yi put down the pen in his hand.

Two minutes after Lin Yi put down his pen, Liu Luran also put down his pen.

She exhaled a breath and raised her head, only to realize that Lin Yi in front of her had stopped answering the question at some point.

"Is it done?" Liu Luran was stunned and asked.

"Yeah." Lin Yi nodded and stood up.

The two took the question to the two old men who were fighting over there.

Seeing Lin Yi and Liu Luran approaching, Mr. Gu waved his hand to signal them to stop talking, and then started the final fight with Mr. Liu Tou.

On the battlefield, the fighting was brutal.

After fighting to the end, Old Liu Tou used two pawns to force Mr. Gu's handsome man to death in the palace.

"Oh, it's unfair to lose this game." Mr. Gu felt a pain in his balls. If the rook hadn't died just now, there would have been a chance to fight. Now in the middle of the game, he can't even kill the two pawns.

Old Liu Tou just smiled and said nothing.

Mr. Gu raised his head and looked at Lin Yi and Liu Luran standing there, and then looked at the time.

"Forty-five minutes? Are you done?" Mr. Gu was stunned.

Seeing Lin Yi and Liu Luran nodding, he took their answer sheets and looked at them.

First, they roughly scanned the answers to the first two questions, and then looked at the answers to the third question.

Mr. Gu's eyes gradually brightened, and occasionally there was a bit of contemplation, and finally there was a bit more approval.
Chapter completed!
