Time Travel: Conditional Wealth

Mathematics competitions have been upgraded and require the use of mathematical knowledge to solve a specific problem. This is called the Mathematical Modeling Competition.

What they want to study is the calculations performed in relatively idealized lake environments and floods.

This modeling actually doesn’t make much sense. After all, when summer floods really happen, they are extremely sudden. There are too many factors to consider, such as the buildings, people, and vegetation in villages and cities.

The roommates often rely on Lu Jinan to feed them to survive. After all, the research money makes the brain hungry quickly. Lu Jinan's seat is piled with a lot of snacks. When he came back from the bathroom, he looked at Zhang Guochao's behavior and said, "Eat it. I've never missed yours."

The three of them started to act after hearing the news. Although it was a good thing to do someone who had done something for you, Lu Jinan's roommate still wanted to say a few words: "Why are they all snacks? Golden cheese stick biscuits, soft bread, soy milk powder, sausages, plums..."

Lu Jinan hummed and wiped his hands with a towel: "If you don't like it, put it down. You eat too much. Can my wife afford it?"

The roommates laughed and said, "Did He Xi buy all of them?"

"She did it herself."

"She is very clever." Hu Yitian suddenly thought of something and asked him, "Who of you two will cook?"

"I." Lu Jinan didn't have the slightest bit of disdain that a gentleman should stay away from the kitchen. "She prepares the ingredients and I cook."

Wang Xingyue glanced at his roommate and said to Lu Jinan, "Cook for us some other day so we can have a taste of your cooking skills."

Lu Jinan looked at him: "No time, no time, we don't even have time to go home."

He was speechless, because the other party had started eating meat.

Being so busy in the next semester, they neglected each other. Every time they met, they talked most about laboratory research problems. He Xi was busy with solar energy problems, which also led to his battery problems. With He Xi's help, Lu Jinan devoted more energy to the mathematical modeling competition.

Until the arrival of winter vacation, the winter night fell quickly, it was still evening, and the sky had already darkened.

The cold wind hurts my face.

Lu Jinan has been overtired recently and has a cold. He wore a mask and walked home holding He Xi's hand.

Most of the students in the school have left. The campus is empty, the leaves have fallen off, and the trees are bare.

He Xi couldn't help but feel scared when looking at the scene in front of him. He had heard before that schools were built on grave circles, otherwise how could they be so big and have so much space.

The winter in the north was as cold as in previous years. He Xi dressed like a fat bear and said, "Why do you want to go home suddenly? We don't have heating at home. It's as cold as outside."

Lu Jinan tilted his head to look at her, smiled and said, "Don't you miss me? How long has it been since we were together?"

Lu Jinan took He Xi's thickly gloved hands and pressed them against his abdomen: "Think about it again, how long have they not felt the warmth of your hands? Have you forgotten about playing hide-and-seek in your brother's abdominal muscles?"

The thick down jackets made it impossible to transfer each other's body heat to each other, and the hot temperature in their hearts was blocked out from the cold wind.

No matter how affectionately they hugged each other, it was impossible. Facing each other, both of them could feel the sticky emotions between them.

Suddenly, He Xi dragged Lu Jinan and ran across the winter campus, saying in a muffled voice under her scarf, "Run, hurry back and turn on the heater. Also, I really need to eat enough this time, otherwise there will be no future."

Lu Jinan was infected with He Xi's fighting spirit and pulled her to run, his eyes slightly curved: "Okay, we'll all be full."

result.

Full and tired, He Xi said breathlessly: "Brother, I really can't do it anymore. Let's fight again another day, another day..."

In fact, Lu Jinan's heart also began to beat, but he had always been craving for the smell of He Xi's body and the feeling she brought him. When He Xi's soft and tender voice appeared, he heaved a sigh of relief. He finally had a reason to stop his inner greed.

Lu Jinan stretched out his long arms and pulled the soft down quilt over to cover He Xi. He put his arm around her waist and patted her gently like he was coaxing a child until He Xi's breathing became light and even.

He Xi slept soundly until noon, until He Fei's voice appeared in her ears: "Xi'er, wake up, what did you do at night? Why aren't you awake yet?"

She closed her eyes and muttered unhappily, "Stop making noise, sleep a little longer."

He Fei was scared away by the apron she was wearing and the cold look from Lu Jinan who was standing at the door: "Let her sleep a little longer."

The meal was ready, and there was also nourishing soup. Lu Jinan sat beside He Xi's bed, stroking her cheek with his fingertips in a rather affectionate manner. After a moment, he said, "Wife, get up and eat. Someone is coming home."

Although she didn't sit up, her body was sore and her legs were so weak, how could she get up?

Lu Jinan's smiling voice was still there: "Does it still hurt? Brother has already applied ointment on you. You have no reason to stay in bed anymore."

A delicate white foot stretched out from the quilt. He Xi stretched her waist and said softly, "I don't want to get up. I'm still very tired."

Lu Jinan imitated He Xi's weak tone: "What should I do? Your sister is here, waiting downstairs like an ant on a hot pot."

He Xi was picked up by Lu Jinan, and as usual, he helped He Xi wash up, including washing her face, brushing her teeth, combing her hair, and taking care of her skin. He was so skilled at this assembly line work that he had done it countless times.

In the end, he was carried and placed in front of the dining table.

He Fei couldn't bear to look at the two of them. She secretly glared at He Xi and mouthed, "You? What did I say to you?"

"Why are you here?" He Xi shut up instantly after she spoke, her hoarse voice announcing their "there is no silver here."

Xiao Yan's mouth could fit an egg. He pointed his fingers back and forth between He Xi and Lu Jinan: "You two? Are you together?"

He Fei looked at him like a fool: "Are you a little stupid? Why do you think they bought the house?"

Xiao Yan didn't say anything, just looked at the ceiling and snorted again. It's not fair, why are they so rich, their lives are obviously the same.

He Fei glanced at the solar calendar not far away and asked: "When are we going back?"

Listening to her tone, I knew without guessing that it was He's father who was "making trouble" again. After a while, he sighed softly and said, "You go back. I'll stay with him. Their competition has reached the stage of numerical modeling. Now it's the provincial competition."

He Fei chuckled: "Do you think our father doesn't know what you are thinking? He also said that if you don't go back, he will spend the New Year at your house."

"My home? How does he know? You or him?" He Xi looked at He Fei and Xiao Yan.

Xiao Yan could only laugh.

"Are you sure you don't want to go back? Aren't you worried that Dad will disturb him and prevent him from fully concentrating on the game?"

Feeling warm on his hand, Lu Jinan covered He Xi's small hand and said, "Go back. He is lonely too. I will come to find you after I am done with my work."

Well, if we don’t go together during the summer vacation, the winter vacation will be the same.
