Xia Lu handed the USB flash drive containing the paper to Cao Zhenggang.

Cao Zhenggang asked Xia Lu to have a good rest this weekend, and from next week, the project will enter a very important debriefing stage.

Xia Lu returned home and chatted with his parents, but he didn't say anything all night.

The next day was Saturday, and the spring breeze was blowing and the sun was shining.

At ten o'clock in the morning, Xia Lu came to the community where Hao Tian lived.

"Building 18 and unit 802, this is it. ”

According to the information sent by Hao Tian, Xia Lu found the location, and he rang the doorbell downstairs.

Hao Tian opened the door, Xia Lu went upstairs, and he came to Hao Tian's house.

Hao Tian was wearing a floral apron, a kitchen knife in her left hand, and a kitchen knife in her right hand, she brandished the kitchen knife, and said with some reproach: "Xia Da is busy, it's not easy to see you." ”

Xia Lu took two steps back and said, "Tiantian, if you have something to say, put down the knife first." ”

"What are you nervous about? This knife is not cutting you, I am chopping vegetables, and I will eat at my house at noon. ”

"Cutting vegetables with two knives? ”

"Ancestral knife techniques, women not men. You sit down first, and the WIFI password is three a, three k, plus 888. ”

Hao Tian went to the kitchen to cut vegetables and cook, and Xia Lu observed Hao Tian's home.

This was the first time Xia Lu entered Hao Tian's house, and he saw that Hao Tian's house was very clean, with three bedrooms and one living room, and the living room was very large.

Hao Tian is very capable, and it was close to 12 o'clock, and four dishes and one soup were served.

Looking at the dishes with all the color and flavor, Xia Lu's appetite increased greatly: "It's hard work, it's sweet, it takes time to make these dishes, right?"

"So you're going to eat it all, and drink the soup first. Hao Tian said as if ordering, and then served Xia Lu a bowl of soup.

Xia Lu drank the soup and praised again and again: "Stewed mutton, stir-fried pork kidneys, cold okra, scrambled eggs with leeks, pigeon soup, these dishes seem to be very replenishing." ”

Hao Tian nodded and said, "You have been working hard lately, and it is healthier to make up for it." ”

Affection from Xia Lu has a +288 valuation

Xia Lu was tonic for a meal, and love surged in his heart.

After the meal, the two sat on the sofa and talked.

Xia Lu hugged Hao Tian and said softly: "Tiantian, after the start of school, I joined my mentor's project team, and I was really busy. But being busy is not an excuse, you can't snub your girlfriend because you're busy, I don't do anything on the weekend, I'll accompany you, and you can do whatever you say. ”

Hao Tian hugged Xia Lu's waist, and she said coquettishly: "Is it okay to go shopping with me in the afternoon, I want to buy a skirt." I used to dare not wear it with thick legs, but now I can finally wear it. ”

"Good. ”

"By the way, Xia Lu, what is your research group studying?"

"It's a long story, but it is a method for solving the optimal system, exact solution, and conservation law of nonlinear partial differential equations that are both universal and applicable to specific application environments. ”

"Mom...... You can tell me the results directly, after all, I am studying English, and I can't understand the technical terminology of science men at all. ”

"As a result, with our efforts, the project has been successfully completed, the paper has been written, I am the first author, and next week I will enter the internal reporting process and report to our school's academic committee. ”

"Xiu. Although Hao Tian didn't understand the jargon of science, she knew that her boyfriend was doing something very good.

"I think the most beautiful operation I did was to get a new exact solution by solving the reduced equation......" Xia Lu unbuttoned Hao Tian's home clothes, slowly unbuttoning them one by one.

"Oh, that's what your project is about......" Hao Tian gradually understood what Xia Lu was doing.

Removing Hao Tian's home clothes, Xia Lu's hand wandered over Hao Tian's skin regularly, and he continued to explain his topic: "This exact solution is a special power series solution, and this solution plays a key role in explaining the complex wave motion...... Tiantian, do you know what wave motion is?"

Hao Tian hummed comfortably: "That's it...... Is this the kind of movement now......"

"It's understandable. "Xia Lu is skilled in deriving wave movements, and through his unremitting efforts, he has made tremendous progress in his scholarship.

The representation of complex wave motion on the data chart is simple and clear, the wave curve changes from smooth to steep, and the ordinate value of the wave peak continues to rise, and remains at a high position after reaching the vertex.

"Badass...... Don't do any wave exercise in the living room...... Go to my room......" Hao Tian was hot, her eyes were misty, her face was flushed, a girl of her age reflected normal academic data, the vertical ordinate value of the peak was at a very high position, and the intersection point o of the coordinate system showed typical hydrodynamic characteristics.

The two came to Hao Tian's boudoir, closed the door, and the curtains were drawn.

Maybe it was because of the home game, Hao Tian suddenly became very active and crazy, she unbuttoned Xia Lu's clothes, pulled the belt of Xia Lu's jeans, and pushed Xia Lu down on her bed.

The two hugged and kissed, and the originally flat sheets became messy.

"Tiantian, it's time to do the swap formula next......"

"Hmm...... How do you interchange the formula?"

"You're above, I'm below, and we form a mirror structure. ”

"Got it...... Actually, it's not that hard for you to do science......"

The two indulged in academic exchanges, forming a mirror structure up and down.

After that, the two kept changing the structural formula, and the academic exchange lasted for nearly an hour.

Emotional valuation from Hao Tian +2328

Affection from Xia Lu is valued at +2298

Xia Lu Ai's skill valuation is +3001

Doing academic exchanges is hard work.

After the exchange meeting, Hao Tian didn't even have the strength to take a bath.

"Xialu, you big badass...... I love to bully others......" Hao Tian, who was lying flat, looked at the paper towels on the bedside table, and said with satisfaction but also shyness: "Help me do the surface treatment...... It's so annoying, so many ......."

"The surface treatment effect of the wipe type is average, let's go for a spray surface treatment. Xia Lu picked up Hao Tian and came to the bathroom.

The spray surface treatment begins, the water temperature is suitable, and the flow rate is normal.

Xia Lu squatted down and carefully helped Hao Tian do local surface treatment.

"Hmm...... Not...... It's so comfortable...... "Hao Tian is a particularly sensitive girl, and she is excited again during the surface treatment.

"Tiantian, turn around, turn your back to me, and you need to deal with it later. ”

"Hmm...... Good ......"

"Lower your body, well, that's it. ”

"No...... Don't!" Hao Tian exclaimed, "Don't stand up and do academic exchanges......"

"Summer Road...... You're back to your initial value so quickly......"

"Hmm...... Let's go to my room...... Standing for a long time, my legs are numb......"

Plans can't keep up with the changes.

Hao Tian's original plan was to go shopping with Xia Lu this afternoon and buy a good-looking little dress.

However, until 8 p.m., the two did not go out.

The relationship between Xia Lu and Hao Tian has grown rapidly.

Xia Luai's academic skills are estimated to have exceeded the 15,000-point mark.
