Chapter 159

Receiving the mission, Xu Qingzhou went out happily. Walking out the door, he couldn't help but take a long breath.

In the afternoon, golden sunlight passed through the sparse branches of the plane trees, leaving mottled tree shadows on the old walls of the residential complex. Walking on the road, one could hear the rustling sound of feet stepping on leaves.

At this time, the atmosphere of the New Year was already very strong. Shops along the street hung up red lanterns and couplets, adding a bit of festive flavor.

When he came back after buying light soy sauce, at the entrance of the complex, Grandpa Zhang, who was on duty, had just changed shifts and was smoking away.

Whenever someone came in, he would tirelessly press the button for the access control.

"Uncle Zhang, on duty?"

"Little Xu~ going to buy things? Your dad just went in."

"He went fishing."

Wang Xiaping couldn't listen anymore and turned to look at the two father and son who were just eating for free, "Do you want me to set up a stage for you two in the complex so you can go up and perform a skit?"

Two minutes later, Xu Qingzhou finally got rid of the grandpas and grandmas and returned home.

"Cough~ Qingzhou, go help your mom peel garlic. I'm going to change my clothes."

Xu Qingzhou glanced at the fish; it was jumping around, indeed different from the sickly fish old Xu usually brought back. It was clearly really caught, so he flattered him, "Tsk tsk, Dad, you caught such a big one? Impressive."

Moreover, with the pearls of wisdom from Zhang Yitang and others, he wouldn't be like a headless fly. Currently, Xu Qingzhou's goal was mainly to improve the sieve method and gradually narrow the scope. However, pushing it forward was also very complicated.

He estimated that he would definitely be lectured by Wang Nushi frequently during this period. With old Xu around, he could also slip away early during the lectures.

In the kitchen, Wang Nushi was dealing with fish scales. It was a grass carp, looking to be about four or five jin.

During the time he had been back, there were already over a dozen messages asking Xu Qingzhou to go out for meals, all of which were various class reunions.

"I'm chatting with my parents in the living room," Xu Qingzhou said with a smile.

After chatting simply for a while, the two hung up the phone. Song Yao let out a breath, in a very good mood, and planned to continue sitting with her parents for a while.

Someone else said, "Qingzhou, you've been back for so long, and you don't come out to walk around, like a young girl who just got married."

"Song Yao."

"Just relying on this puff of smoke~" The old man smiled and waved his hand.

"It's fine, I won't be cold once I start moving." Xu Qingzhou chuckled, rolled up his sleeves, and went up to help.

At this time of day, the old ladies and old men walking outside hadn't gone home yet.

At six in the evening, it started to snow lightly outside. The cold wind carried snow particles against the window. It was very warm inside, and the fragrant food had already been placed on the Xu family's dining table.

At 11:40, Xu Qingzhou picked up his phone and ducked into the bedroom.

Sure enough, he had only walked a few steps when he met the neighbor next door.

"Happy New Year."

"Maybe it'll be soon too." Xu Shouyun drank his tea and also began to look forward to it.

"This child, I always felt he would have great success in the future. Look, isn't he a celebrity now?"

"I didn't disturb you, did I?" Song Yao sat on the bed, her fingers touching the glass, which had a layer of mist condensed on it. She gently traced on it with her index finger.

"Yo, haven't seen our great scientist for a long time."

"Good."

"Your dad is eavesdropping." Zhang Junli coughed dryly.

Hearing old Xu complain about his fishing buddies, completely ignoring that he was also a master of coming home empty-handed, Xu Qingzhou found it funny and praised him insincerely, "Two fish? Impressive, impressive!"

Xu Qingzhou looked at the brilliant fireworks outside the window and said, "Happy New Year."

"It's so good, without realizing it, this brat has already become an adult." Wang Xiaping sighed.

Xu Qingzhou shook his head helplessly, carrying the light soy sauce as he walked home. He vaguely remembered that the old man seemed to have had a serious illness, and only then did he completely quit smoking.

Xu Shouyun also had a look of nostalgia, "The child grew up too fast."

"It's a pity, there was an even bigger one, at least 8 jin, but it got off the hook."

In some respects, the Twin Prime Conjecture and the Goldbach Conjecture are not truly parallel. For example, for the Twin Prime Conjecture, the a=-2 in the Bombieri-Vinogradov theorem is a fixed value. Old Xu raised his eyebrows triumphantly, feeling he had finally proven himself, and began to talk about his glorious achievements, "Caught two today, and a small one, gave it to old Cheng. Heh, this guy squatted for an entire afternoon and didn't catch a single one."

"Reading books at home."

"You're going to the countryside to pay New Year's calls, right?"

"No wonder he could get into Jingda, he's reading even during the holidays."

On this day, Xu Qingzhou didn't wake up until 10 in the morning. No way around it, he stayed up until past two last night.

Song Shisong and Zhang Junli stood at the door, seemingly not expecting their daughter to finish the call so quickly.

After eating, they sat on the sofa watching the Spring Festival Gala.

"Where's my dad?" Xu Qingzhou laughed it off.

Not as ethereal as the Goldbach Conjecture.

Days at home passed quickly, and in the blink of an eye, it was the 30th day of the twelfth lunar month.

Seeing Xu Qingzhou only wearing two layers of clothes, Xu Shouyun said, "Put on another layer, it's cold outside. The weather forecast says it's going to snow tonight."

"Oh oh, okay."

Xu Shouyun took a bottle of wine out of the cabinet and poured a little for all three of them.

Xu Qingzhou smiled gently, "My parents would love for you to disturb me like this."

Before leaving, Xu Qingzhou said with a smile, "Smoke less, it's bad for your health."

Seemingly hearing that Xu Qingzhou was up, Wang Xiaping poked her head out from the kitchen, looked at him, and then placed a bowl of dumplings on the table.

After washing up and eating the dumplings, Xu Qingzhou ran to the balcony to help. Opening the balcony glass, he could smell the scent of burning pig hair. Inside the complex, one could already hear the sound of firecrackers popping.

In the bedroom, Xu Qingzhou pressed the answer button, and the girl's pleasant voice rang out on the phone, "Why did it take so long to answer?"

Xu Qingzhou smiled gently, "Auntie Hu, what scientist? I'm just a student."

Wang Xiaping said again, "The only regret is that there are too few of us in the family, we can't even gather a table for mahjong."

Old Xu had indeed already returned.

"Mm."

Let these two resolve their own affairs. The lively atmosphere of the festival blew away some of the winter cold.

"You two, father and son, be quick."

"Yes, the old man at home has been nagging for us to go over for a long time."

"Got off the hook? What a pity~"

Time reached 12 o'clock, and it seemed the whole world became lively.

In winter, even in Rongcheng, the wind blowing by is chilly.

Wang Xiaping gestured toward the balcony with her chin and said, "They're burning a pig's head outside, hurry up and go help after you finish eating."

The original plan was to call Guo Ziyang and Ding Jiahui out for a meal, but the two seemed to be sulking at each other. When asked, both said they had things to do. Xu Qingzhou and Song Yao were helpless and temporarily gave up on the meal plan.

Although they were a bit at a loss at first, these days were not without gains.

She opened the door, and their eyes met.

Song Shisong: "?"

During the few days of the New Year, Xu Qingzhou really didn't look at any materials. To be precise, he didn't have the time. These two days he was either paying New Year's calls or on the way to pay them.

During this time, he went back to his hometown once to visit his grandparents and maternal grandparents who were living in the countryside.

On the sixth day of the first lunar month, the family returned to Rongcheng with a car full of things—the trunk was even stuffed with an old hen.
