After May Day, the weather tends to be hot.

Xia Lu's freshman year is coming to an end.

Looking back on the more than a semester I have spent, Xia Lu has been quite fulfilling, with full marks in regular courses, a project, a few swimming championships, a girlfriend, and a house.

There is also pressure.

At present, the pressure on Xia Lu mainly comes from mortgages.

With a down payment of more than 2.5 million yuan, Xia Lu's parents have to repay a mortgage of 10,000 yuan every month.

This fixed expenditure of 10,000 yuan was not available before, because the second house was bought, so Xia Lu's family increased the financial burden of 10,000 yuan per month.

The Xia family's stable source of economic income is Honghua convenience store.

The convenience store will not make a profit of +10,000 yuan per month because the Xia family bought a second house.

So where does the new economic income growth come from?

Xia Lu set his sights on his 600,000 yuan "Outstanding Undergraduate Science Innovation Fund".

It is absolutely not allowed to take the 600,000 yuan to repay the mortgage.

Xia Lu didn't dare to do this.

For each expenditure of the 600,000 yuan science innovation fund, Xia Lu must give details and bills that meet the requirements of the system.

The information Xia Lu has is that he can use the 600,000 yuan to carry out any scientific innovation research within three years.

If there are no research results within three years, the money will be returned to the school.

If the research results are published, the school will reward Xia Lu according to the academic value of the research results.

For example, Xia Lu spent 300,000 yuan to make a scientific innovation.

The school will give evaluation opinions on the scientific innovation made by Xia Lu, which is roughly divided into several grades of excellent and medium difference.

If the school's evaluation is excellent, then Xia Lu can get the remaining 300,000 yuan, which is his reward.

If the evaluation is good, then the reward received by Xia Lu will be reduced.

If it is, then Xia Lu can get a symbolic consolation bonus of several thousand yuan.

If it's bad...... Then Xia Lu is embarrassed to take the bonus.

So here's the problem.

What kind of scientific innovation research is done with the least research expenditure and the highest academic value?

Xia Lu's initial idea was to prove what conjecture and other questions were most in line with his actual situation.

That classmate Liu just proved Sitapan's conjecture, and he became famous.

Just such a Sitapan conjecture actually made three academicians write a letter of recommendation for Liu, and strongly recommended that Liu be admitted as a graduate student.

There are many more conjectures than the Sitapan conjecture, there are Goldbach conjecture, Riemann conjecture, Hodge conjecture, BSD conjecture and so on.

Prove any one, and you will definitely get an excellent evaluation.

For example, if my brother guesses that it is really proved by my Xia Lu, the value of this academic achievement is more than 300,000 or 600,000?

That's all it takes for three academicians to write letters of recommendation or something.

Goldbach conjectures that no academician in the world can do it.

Hahahaha!

It's developed!

"System, is there a proof method for Goldbach's conjecture, I want to buy a copy. ”

Xia Lu entered the system mall, and he was surprised to find that he was in a groove!

Actually not!

There are currently only two fixed products in the system store, the brain card and the body function card.

Xia Lu: "System, what conditions is the method of the nonlinear partial differential equation you sold last time on the shelf?"

System: "Random listing." ”

Xia Lu: "Is there such a possibility, on a certain day, in a certain year, month, and day, the mall will randomly put on the shelves the Gochai, Riemann conjecture, Hodge conjecture, BSD conjecture, or the Yang-Mills equation, N-S equation solution proof method?"

System: "Can't answer." ”

Xia Lu: "Then you can put an academic commodity on the shelves for me now, anything." ”

System: "The host's Brain Power level is insufficient, please increase the Brain Power level." ”

"......" Xia Lu didn't want to talk to the system anymore, he was bored.

Of course, the system does make sense.

If Xia Lu's brain power is increased to Elite 3 stars, Tyrant or higher.

Then Xia Lu may not need any proof methods sold in the system mall.

When the mental power reaches a certain height, you can also give a proof method of what conjecture by yourself.

Theoretically, it is.

Therefore, it is imperative to improve the brain value.

Elite 2-star brain power is upgraded to 3-star, which requires 50,000 points.

"50,000 points...... Where to do it?" Xia Lu was in a tangle.

The feelings, skills, and knowledge that can be sold, Xia Lu has basically sold them.

The rest is very precious to Xia Lu.

If Xia Lu wants to continue to get stronger, then the price he pays will be higher and higher.

Bite!

Xia Lu's mobile phone rang a chime.

A WeChat message from Hao Tian: "I bought you a pair of swim trunks, and we will eat together at noon, and I will give you the swim trunks." ”

Xia Lu replied: "Okay, old place. ”

Approaching 12 o'clock, the two met at the old place, Xia Lu ordered a bowl of ramen, and Hao Tian ate sushi.

"I love the color of these swim trunks, you must be handsome when you wear them to swim competitions. Hao Tian took out swim trunks from her bag and handed them to Xia Lu, she knew Xia Lu's size very well.

"Thank you. Xia Lu took the swimming trunks and said in his heart that he would have to spend money again.

Every time Hao Tian gave Xia Lu a gift, Xia Lu would give her back.

A man can't keep his girlfriend spending money for him.

How much money does girlfriend spend, Xia Lu usually spends back on her in the form of an equivalent.

Some time ago, Xia Lu bought Hao Tian skirts, socks, pants and bra, he gave these things to Hao Tian, and then helped Hao Tian take them off one by one, from the outside in.

You give me a gift, I give you a gift, put it on, take it off.

Men and women come and go, and it's the businesses that really benefit.

"Summer Road...... emmm…… Would you like to go to my house on Saturday?" Hao Tian said a little shyly.

"Are you going to your house again? Your mother is on a business trip again?Your father hasn't returned from a business trip yet?" Xia Lu hadn't been to Hao Tian's house for a while, and he knew that once he went, it would inevitably be another hard battle.

"My dad hasn't come back yet, my mom is home on Saturday, and she wants to see you. Hao Tian was a little apprehensive, she wanted Xia Lu to see her mother, but she didn't want Xia Lu to see her mother. Do you want to or don't want to? That would only be known when Xia Lu met her mother.

"Teacher Yin wants to see me? Okay, I'll go to your house on Saturday." Xia Lu knew Hao Tian's mother, who was an English teacher at Jiangcheng No. 2 Middle School. Seeing Teacher Yin at school is different from meeting Teacher Yin at Hao Tian's house.

"Oh, then you come to my house around ten o'clock on Saturday morning. Hao Tian laughed, it seemed that she was still quite willing to see her mother in Xia Lu.

"Tiantian, let's go upstairs to the mall. Xia Lu said, and then came to the shopping area upstairs with Hao Tian.

Hao Tian has learned the news of Xia Lu's house purchase, she admires Xia Lu more and more, Xia Lu does not fight for his father and does not rely on his mother, he overcame scientific problems with his wisdom and talent, and received a lot of rewards to buy a new house of more than 2.5 million yuan.

Hao Tian held Xia Lu's arm, she enjoyed being with her beloved boy and this excellent boy.
