In fact, it only took Niu Xiaoqiang two and a half days to assist Professor Watson in completing the huge calculation work, and both of them were so tired that they didn't continue to work that afternoon, and went home to rest.

When Niu Xiaoqiang got home, Kailina was answering the phone, Niu Xiaoqiang walked lightly, walked to the sofa and sat down.

When Karina hung up, he asked, "Who's calling?"

The phone at home is mainly used by Niu Xiaoqiang, and Kailina did not tell this number to others. Niu Xiaoqiang thought that it was his acquaintance who called, so he asked this question.

Karina replied, "It was Caroline who called, and she said that she had already handed over the purchased computer to the shipping company you had designated, so that you could keep an eye on the situation at the shipping company." ”

Niu Xiaoqiang nodded and didn't ask again.

Karina wondered, "Why did you come back so early?"

"I'll be back when I'm done. ”

"Anyway, it's still early, why don't I take you to buy a car now, and after you buy the car, will you come home with me?" My mother called and said that there was a party at home tonight, and she wanted me to go back with you. ”

Niu Xiaoqiang was originally stretching, but when he heard this, he turned his head to look at Karina: "Not long ago, your mother just held a party, why is there another party so soon? What kind of party is this time?"

"My mom said it was a community-based gathering, mainly to discuss the safety of the community. ”

Niu Xiaoqiang hesitated: "Hasn't our community always been safe? Why do you suddenly want to discuss this issue?"

Kailina handed a newspaper to Niu Xiaoqiang: "This is today's Boston Daily, you will understand it after reading it." ”

Niu Xiaoqiang took the newspaper and looked down, only to see a bright red headline written on the front page: "Ivy Professor and his wife were killed!"

The Ivy League is a consortium of top schools composed of universities, and the Massachusetts Institute of Technology, where Niu Xiaoqiang studied, has not yet joined the Ivy League, and Harvard University, which is not far from MIT.

After reading the report, he felt a little incomprehensible: "What is there to discuss here? According to me, this case is just a probability event, just like a person who was killed by lightning, although it is very rare, but it will always exist, and this is a probability event, so there is no need to worry too much." ”

Karina shook her head: "Don't forget that the neighbors in the community where you live now are all professors or teachers from various universities, if the murder happened in our community, it is not a small probability event, seeing that their peers were killed, can these people not worry about their safety?"

Niu Xiaoqiang smiled bitterly: "Okay, let's go to your house for a party after buying a car, I'm also a member of the community, it's okay to go and see, have you eaten? Do you want me to make you something to eat?"

"I've already eaten it, what about you?"

"I had lunch at school, and since we've all eaten it, let's go buy a car now. ”

Karina nodded, "Well, I'll go change my clothes." ”

Karina spent a quarter of an hour changing her clothes, and Niu Xiaoqiang sat in the living room waiting. When Kailina came out after changing her clothes, Niu Xiaoqiang immediately got up, and the two stopped a taxi and rushed to the second-hand car market.

Located on the edge of downtown Boston, this second-hand car market is a rural-urban area in Chinese terms, and the environment is not as good as the bustling downtown, with slightly dated roadside houses.

After getting out of the car, Karina tidied up her long black skirt and told Niu Xiaoqiang: "The boss here is my mother's acquaintance, don't talk nonsense later." ”

Niu Xiaoqiang hesitated: "Are you worried about what I'm talking nonsense?"

"Of course it's our relationship, if the other party asks, you can say it's my business partner. ”

Niu Xiaoqiang couldn't help but smile dumbly: "I didn't expect you to make this request, if you don't say it, you won't say it, anyway, it won't affect me." ”

Kailina nodded and walked into the courtyard with Niu Xiaoqiang. On the wall of the courtyard is a billboard that reads "Lausanne Used Car Market".

After Niu Xiaoqiang followed Kailina into the courtyard gate, he found that several customers were picking up cars inside, and he was a little surprised by this: "I really didn't see that the business here is so good, and there are so many customers on weekdays." ”

Karina whispered: "The owner here is very honest, he never hurts customers, and over time word of mouth has spread throughout Boston, which is why business is so good." ”

Niu Xiaoqiang nodded slightly, and was just about to say something, when a hoarse woman's voice suddenly sounded: "Kailina, why are you free? I haven't seen you for a few months, you are getting more and more beautiful, it's just thrillingly beautiful." ”

Niu Xiaoqiang turned his head to look, and then couldn't help but be stunned.

Under the pergola on the right-hand side sat a woman smoking a cigarette, who looked only a little older than Karina, but much rougher than Karina.

The rough mine here does not mean that the person has to look like a man, but that her temperament is very rough. This woman is not only not ugly, but also very beautiful, revealing a strong wildness all over her body.

It's early autumn, and the temperature in Boston is still a bit on the high side, and this woman is wearing a very short pair of denim shorts on the bottom half and a small white tank top on the top half. If she doesn't have a cigarette in her hand, she's a standard hot girl. Even with a cigarette, she looked harmonious, as if she was born to smoke.

Niu Xiaoqiang had such an idea in his heart: Maybe it's because she smokes too much, so her voice is a little hoarse, right?

"Lausanne, long time no see, I brought a friend to buy a car today, this is my business partner, he is from China, his name is Niu Xiaoqiang. ”

Luosang spit out the smoke ring with a smile, stretched out his right hand and greeted Niu Xiaoqiang: "Hello friends from China, I don't know what car you want to buy?

Karina whispered beside her: "If it weren't for the relationship that I didn't know very well, Lausanne wouldn't serve the guests." ”

Niu Xiaoqiang hurriedly thanked him: "Thank you Miss Lausanne for your hospitality, can I go and see it myself?"

Lausanne happily picked up a large number of car keys from the chair he was sitting on just now and handed them to Niu Xiaoqiang: "No problem, this is the car key, they have all been numbered, you can test the car casually." ”

Niu Xiaoqiang thanked him again, and then turned around with the car keys to pick up the car.

Niu Xiaoqiang has no special requirements for the model, as long as he can see it, what he really values is the quality of the car.

Kailina did not follow Niu Xiaoqiang to watch the car, she was pulled under the pergola by Lausanne, and the two chatted while drinking coffee, looking very familiar.
