Chapter 157: Good, the Dagger is Revealed

Xu Qingzhou: "..."

Is this the feeling of lifting a rock and hitting one's own foot? It's too damn painful.

"No, it was just a coincidence," Xu Qingzhou denied it flatly. This second cup of milk tea tasted better than the one just now, although it was a bit full.

Song Yao nodded, stared at him, and asked again, "A girl who is so beautiful and good-looking shows initiative to you. Do you have any heart-moving feelings in your heart?"

Hehe, she even started to stab the heart.

Xu Qingzhou shook his head decisively and said, "No."

Song Yao retracted her gaze and walked toward the residential area. The two walked on the road, their shadows under the streetlights stretched very long, intertwined together.

"Heard Old Zhang say his son is coming back this year," Xu Shouyun drank some tea.

Read! {

This afternoon at 3 o'clock.

This guy is too annoying. He actually thought about being heart-moved?

Thousands of miles away, Xu Qingzhou laughed, thinking to himself, Old Xu, being so far away, still acting cool for his foster father, it's hard for you.

"That's true," Xu Shouyun nodded in agreement.

The Jingda competition team chose Question A, and there was an English version of the original question in the group.

Another two days passed, just in time for the weekend.

Roughly, it is to build a realistic, reasonable, and useful model, considering the spread of the disease, the amount of medicine needed, possible feasible delivery systems, and the location of delivery.

Thus, the group fell into silence.

Zhang Junli hesitated for a while and asked Song Shisong, "Should I go and ask again?"

"Come in and eat fruit," Wang Xiaping's voice came from the living room.

Looking at her son, Wang Xiaping said disgustedly, "Just know how to lie on the chair and bask in the sun. I think you shouldn't be here, you should be with the grandpas and grandmas in the community."

"Bully? You mean Little Xu?" Song Shisong laughed dumbly, recalling the scene of the meal that day, "I think our daughter wouldn't bully others, that's already good."

Xu Qingzhou was lying on the rattan chair, squinting his eyes to bask in the sun. After basking for a while, he picked up his phone to look at the group messages. During this time, what everyone was discussing most hotly was the MCM competition.

Not long after, they arrived at the entrance of Song Yao's residential area.

Zhang Shuyi: "Wow, you guys are all so amazing."

Zhang Junli said angrily, "You are big-hearted. What if our daughter is bullied?"

"The growth rate of the infected population is equal to the rate at which exposed people turn into infected people, 【\frac{di}{dt}=\sigmae-(\ga"

Bedroom, Song Yao sat at the desk in a daze, but had no intention of reading.

Xu Qingzhou washed his hands and came back, peeled an orange, handed it to Ms. Wang and Old Xu, and seeing them shake their heads, he ate it himself, clicking his tongue, "It's still comfortable at home."

Xu Zhengyang looked at the old Kong and the others who were discussing with an aura of acting cool in the screen, snorted coldly, and then typed: "Old Xu, what do you think?"

Kong Xianbo: "I think we must add the exposed (exposed, e) state. The body does not show symptoms immediately after being infected with the virus, but it is already infectious."

【problema: eradicatingebolatheworldmedicalassociationhasannouncedthattheirnewmedicationcouldstop】

Zhang Junli and Song Shisong looked at each other and shook their heads helplessly. After returning, they also asked what the relationship between their daughter and Xu Qingzhou was and whether they were already together.

This is a problem of eradicating the Ebola virus.

"Forget it, let them solve the young people's business themselves," Song Shisong smiled lightly. "Whether your heart moves has nothing to do with me," Song Yao glanced at him, thinking in her heart, if Xu Qingzhou really did this, should she beat him until he couldn't take care of himself, or just sink him into the river.

Hehe, the dagger is revealed, right?

"It's said that he will come back next year," Wang Xiaping didn't believe it, paused, and sighed, saying, "It's just because there are no grandchildren, otherwise it wouldn't be so deserted."

"Hehe, it's like this now, what will it be like later."

Xu Qingzhou broke two pieces of orange and threw them into his mouth, still not taking this topic.

Xu Shouyun was sitting with his legs crossed watching the ball game, and said without looking back, "I support Qingzhou on this point. Boys, career is paramount."

Xu Qingzhou stood up. The old couple was watching TV in the living room, and there was a fruit plate on the table.

"Heh, comfortable at home, and still managed to come back on the 20th of the twelfth lunar month?" Wang Xiaping rolled her eyes at him, "So busy at such a young age..."

Xu Qingzhou took a look and lost interest. This question is not difficult. It needs to use the classic SIR (Susceptible-Infected-Removed) model as a foundation. It's just that the whole process is very cumbersome and requires three people to cooperate. And in the professional group, Kong Xianbo, Liang Quanjie, and Shao Jiuming were having a fierce discussion.

Kyoto, in the room of the courtyard.

"Coming."

"Mom, your face changes too fast. A few days ago, you told me not to be so busy," Xu Qingzhou sat on the sofa. Just as he reached out, his claws were slapped away by Wang Xiaping, "Go wash your hands."

Before leaving, Xu Qingzhou was a bit curious and said with great courage, "What if I am really a little heart-moved?"

Wang Xiaping continued to nag, "And the son of the old Wang family, he is almost 30 years old, and he is still wandering outside all day, not even looking for an object."

Xu Qingzhou raised his eyebrows and kept silent wisely. He always felt that the old couple's intention was not in the wine.

Liang Quanjie: "Mainly, we must add critical patients (critical, c) and dead people (dead, d) states..."

Zhang Junli couldn't help laughing. This sentence was really not wrong. She knew her daughter too well, and her combat power was not weak.

!.

Song Yao got angrier the more she thought about it, picked up the doll Xu Qingzhou caught, and gave it two punches. After hitting it, she felt relieved, hummed lightly, and continued to lower her head to read.

Song Yao went home, greeted Song Shisong, said she was a bit tired from shopping, and went straight back to the room.

Wang Xiaping sighed, her brows knitted together, "Look at Old Zhang's son, he hasn't come back for the New Year for three or four years. Every time during the New Year, the old couple is cold and clear..."

Shao Jiuming: "I have read the A papers of the previous American competitions. Actually, it is not that simple. Basically, they will build a variant model of SIR, such as the SEIRCD model,"

Xu Qingzhou gave two dry laughs and couldn't help but tighten his clothes. Just now, his back felt a bit cold. What was going on?

Song family.

Xu Qingzhou had been staying at home reading, studying the Twin Prime Conjecture, occasionally carrying a rattan chair, drinking tea and basking in the sun on the balcony, living quite comfortably.

But the daughter denied it, saying that she and Xu Qingzhou were just ordinary friends.

Good, don't ask such dangerous questions next time.

"It's not easy to find now," Xu Shouyun sighed.

When Wang Xiaping spoke, she squinted at Xu Qingzhou, "Yes, before, the vision was high. At eighteen or nineteen, she said she was not in a hurry, but now she is still an old bachelor."

Xu Qingzhou: "..."

This fruit tastes tasteless.
