With the development of mathematics, it is inevitable that the Lagrange multiplier method will be discovered, as for what it is called in this life and this life, Feng Han does not know, he reviewed it in the library for a while, and then introduced this algorithm into the above problem, and only took just one-fifth of the length to complete the proof.

Before Zhu Peiqi and the others could react, Feng Han had already completed the argument and called it a day!

"How is it possible, so fast!"

"It seems to use knowledge points that we don't know~"

"What kind of algorithm is this, I haven't seen it!"

"I don't understand this! I don't admit it!"

"Is this right?"

Everyone scrambled for the manuscript paper in Feng Han's hand, and in the end, Xiong Di made the final decision, "This seems to be the algorithm invented by Ji Qi multiplier, and the algorithm invented by the mathematician Ji Qi of Later Xuan is more than a hundred years earlier than the West!"

"That's right, it's Ji Qi multiplier method!I saw it when I read "History of Mathematics"!" Xiong Di held Feng Han's arm a little out of shape, "Brother, how do you know how to learn mathematics in college?!"

Feng Han looked at Zhu Peiqi and the others indifferently, "Read more~"

After Feng Han explained this kind of Ji abandon multiplier method, Zhu Peiqi and the others still gave him the money even if they were reluctant, this is a full-line rout of high-quality students against scumbags! Shame!

The money was in hand, Xiong Dila sealed the cold, "I almost forgot about business, I'm about to pick up the bride, you come with me!"

Feng Han is going to act as Xiong Di's fortune boy today, Xiong Di handed a bag to Feng Han and told him, "Although the skin of the red envelope is the same, but the inside is different, there are two layers here, this layer is a small bag of 10 yuan, and the other layer is a big bag of 100 yuan, the big bag is thinner, because there is only one, but there are 10 small bags, so it is thicker. ”

"It's too complicated, why don't you give me an equation~"

"Less, I actually remember my answer word for word, and I can also skillfully use the Ji Qi multiplier method, I've just heard of it, otherwise, I'll copy your homework in the future~" Xiong Di joked about Feng Han.

"Don't don't, don't, I'm too lazy to use my brain, if I didn't have money to make today, I wouldn't play with them, your classmates are really funny, your classmates are married, and they come here with their summer vacation homework, are they usually like this?" Feng Han said with a smile.

"The learning atmosphere in our class is really strong~" He also has nothing to say to this group of students.

Feng Han took the red envelopes in the bag: "It's a pity, why didn't Xiaolu marry you, so that I could still mix a few red envelopes." ”

"I think what you really regret is that you didn't go to Xiaolu's side to pretend to be your mother's family~" Xiong Di squinted his eyes.

"Haha, what's that, it's a good day today~"

The auspicious time has arrived, the sedan chair man lifts the sedan chair, the driver opens the way, the mighty team rushes to the deer's house, the weather is really good, the sun is shining, there can be 378 degrees ~

Originally, the normal procedure was that the groom rode a tall horse to greet the bride, but the society is developing, the times are progressing, and Dongyang is also a modern and extremely developed bustling city, livestock is forbidden to go on the road, so I have to combine ancient and modern, but I heard that in some more developed cities, the sedan chair has long been replaced by a float.

Fortunately, the distance is not far, otherwise the master of the sedan chair is afraid that it will be time for heat stroke.

The deer family is not as rich as the Xiong family, there is no independent courtyard, in the community, in order to ask for red envelopes to block the sedan chair bear children have set up a phalanx early, at home, Lu for the horse answered a phone call, wife Gao Qiao asked, "Why, can't she come?"

Lu nodded for the horse: "Although I have the ointment given by my in-laws, there are still some traces on my face, and you also know that public figures care most about their faces, and they are willing to go out to meet people when they say that they are fully recovered." ”

"If you want me to say, it's okay if you don't come, if someone like her really appears here, who else cares about our daughter, I'm afraid that we will invite the paparazzi," Gao Qiao asked again, "Then she will live in our house from now on?"

"Yes, she has decided to come back to school, naturally she lives in our house, how good it is, marrying a daughter, and having one more. The deer smiled for the horse.

"I'm afraid that she is used to living in a big villa and can't look down on our small family. Gaucho said with some annoyance.

"How could it be, she is a member of our Lu family, and she can still dislike her own family. ”

"Don't forget, you haven't been in touch for 14 years, and she won't call anyone when her mom takes her away. "Gao Qiao was a blow to the head, and the family invited such a living Bodhisattva, and I don't know if it was a good thing or a bad thing.

"DuangDuangDuang!" Xiong Di has broken through the defense line of several imps, and of course, the red envelope has also lost a lot.

Now, at the last level, he didn't even let the door in as expected, and the door was easily knocked open, but inside, there were still Lu Haoge's aunts, aunts and cousins blocking Lu Haoge's house.

"Sisters, aunts, isn't it just a red envelope, come to me to get it, but please get out of the way and let the big bear pass, okay. Feng Han greeted him with a smile and greeted the women.

And Xiong Di had already met Lu Weima and Gao Qiao, and someone next to him coaxed, "Call someone, why don't you call your parents!"

Feng Han was surrounded by the big girl and the little daughter-in-law, and was about to support the shy Xiong Di, where Xiong Di had already knelt down for Lu Weima and his wife, obediently kowtowed three times, and called sincerely, "Dad, Mom!"

Feng Han can understand Xiong Di's gratitude to the two of them, it can be said that if there was no Han Shiqun back then, Xiong Di might not have been born, and if there was no deer for horses, he would probably lose his mother at an early age.

16 years ago, Han Shiqun drove on a small road and met a woman with a big belly, she was lying in the middle of the road, there was blood dripping under her body, and there was no one left and right.

However, when Xiong Di was born, Tan Ji encountered heavy bleeding again, although the child came back to life, Tan Ji was on the verge of life and death.

Tan Ji is RH negative blood, which is often referred to as panda blood, which is a rare blood type in China, so she has blood in the blood bank of the hospital where she works just in case, but the problem is that Han Shiqun sent her to another hospital, and the time was a little too late.

Because Lu continued to transfuse blood for the horse, it lasted until Tan Ji's own blood was transferred from the hospital, so that she was out of danger, so Xiong Tie Jianlu, Ma Han Shiqun, three men of different ages and occupations, became good friends.

Because of the great kindness of the deer for the horse to their mother and son, and the fact that they raised such a good deer Haoge, Xiong Di's sincerity and sincerity are full of gold.

Deer smiled at each other, pushed open the door, and let Xiong Di in.

And Lu Haoge, who was stealing dessert, saw that the big bear came to pick him up, so he hurriedly put down the dessert and dropped the hijab, to keep being shy.

Seeing that a few cousins and female classmates were about to go in to make things difficult for Xiong Di, Feng Han hurriedly closed the door and let the big bear and deer get along alone and play freely, at the cost of the red envelope on his body being robbed of not much, and it seemed that someone had touched his chest muscles, and he didn't know who was secretly doing it, he had to say - there is vision!

Because the wedding was held at dusk, the time was absolutely sufficient, in the boudoir, Lu Haoge leaned on Xiong Di's shoulder, the deer was about to get married, even if the personality was big, it was inevitable to be sensitive and melancholy at this time, after the wedding, he really changed from a girl to a wife, eh, a 16-year-old wife, it's exciting to think about it!

After chatting for a while, Xiong Di looked at the time, "Xiaolu, or, let's go." ”

Lu Haoge reluctantly said, "Eh, it's going to be water spilled soon." ”

"Rest assured, it won't take a few days to get it back. Xiong Di comforted, but Lu Haoge listened to it and became even more melancholy.

Until Xiong Di said, "When you get to my house, you can collect the money!"

"Don't leave yet!" Lu Haoge hurriedly looked for his shoes.

Xiong Di picked her up and put her on his back, "Don't touch the ground, I'll carry you!"
