That's how buying a car.

At the beginning, I was planning to buy a scooter within 100,000 yuan.

Self-comfort, the car, there is no need to buy it so good, just be able to shelter from the wind and rain.

When I actually buy it, I think, after all, I spent so much money, why not add some money to buy a better one?

Then it changed from a domestic car to a joint venture car, and the configuration was also a low configuration of a naked car from the beginning, all the way to the installation, LED light group, panoramic sunroof, leather seats, leather heating, keyless entry, one-button start, paddle shifters, I can't wait to be on him.

The budget has changed from less than 100,000 yuan at the beginning to 120,000, 150,000, 170,000, and has reached the watershed of 200,000......

Zhou Wen is like that.

It took a lot of effort to buy Q3 from the beginning, but now I start to worry about Q7.

The point is, since you have already taken out a loan, why not buy a better one?

And the income can also support it.

Now the question is, whether to buy the A7 or the Q7.

To be honest, the appearance of the A7 supercar is really beautiful, what boy doesn't have a supercar dream?

However, compared to the riotous A7, Q7 is more in line with his low-key ideas in all aspects.

Zhou Wen asked Shen Xue: "Which do you think is better, A7 or Q7?"

Shen Xue turned her head to look at the two cars in the center of the field, and said with a smile: "It's all good, it's up to you." ”

"It's like I didn't say anything. ”

Shen Xue pursed her lips and smiled.

Zhou Wen decided to ask his sister-in-law.

After all, it's hundreds of thousands, and it's too late to regret it when you buy it back.

Zhou Wen walked aside and called his sister-in-law, "Hey sister-in-law, which one is better, A7 or Q7?"

"It must be Q7, so I still need to ask. A7 that goods, Wen can't be a business boss, Wu can't get off the track for hand-to-hand combat, and the family can't pull people to load goods, and it's easy to be mistaken for a street car......

Except for the appearance of the big slippery back, none of them can catch up with the Q7.

The appearance of aesthetics changes every three years, and you can't keep what shape you will like in three years, but the powertrain and the foundation of the space are the ...... you really have to face every day."

As soon as my sister-in-law mentioned the car, she immediately gushed endlessly, and only after she finished talking did she remember to ask: "Oh yes, Lao Zhou, are you going to buy a car?"

Zhou Wen: "Loan." ”

When my sister-in-law heard this, she hurriedly said, "Loan a little money, how much is the difference, buddy lend it to you." It is annoying to take out a loan to buy a car, and you have to check the bank flow, and if the first-class water is not up to the mark, the loan will not be approved. ”

Zhou Wenyi heard: "It's so troublesome?"

Sister-in-law: "What do you think? Tell me, how much worse?"

Zhou Wen was moved in his heart, worthy of being a good brother, "500,000." ”

Sister-in-law: "I'm sorry, goodbye......"

"Doot-doo-"

Zhou Wen looked at his phone, his sister-in-law was really fucking hung up, "Fuck it-"

Then Zhou Wen couldn't help laughing again.

My sister-in-law is the second generation of demolition, not the second generation of rich, although there are many houses in the family, but they have not been sold, it is no problem to borrow more than 100,000 or 200,000, 500,000 is really difficult for him.

Zhou Wen walked back and said with a smile: "It's late today, let's come over for a test run at noon tomorrow." ”

The salesman smiled and said, "Do you want to make an appointment for a test drive?"

"Yes. ”

"Okay, please come with me to register......"

......

After lunch the next day, Zhou Wen pulled Shen Xue and Zuo Mengmeng to the 4S store for a test drive, and gave opinions by the way.

They test-drove the 2018 Q7 Tech.

After all, the car with a landing price of 700,000 yuan has good performance in all aspects, such as power, driving comfort, and interior.

In terms of power, the technical model is equipped with a 3.0T supercharged V6 engine with a maximum horsepower of 333/ps, a maximum power of 245 kilowatts, a maximum torque of 440 Nm, and an 8-speed automatic manual transmission, with a 000 acceleration time of about 6.2 seconds.

In terms of chassis, the suspension structure has multiple links at the front and rear, and it is equipped with full-time four-wheel drive as standard, but it is not equipped with air springs, but the overall chassis texture is still very high, and all kinds of vibrations can be well handled.

In terms of interior, the sense of science and technology is very prominent, with a large telescopic screen, electronic gear lever, and MMI operating system, full LCD instrument, and transverse air conditioning outlet.

In particular, the transverse air conditioning outlet is very forced.

Zhou Wen decided, just buy Q7.

Then I went back and installed a 360° panoramic camera, Bose audio, etc.

In the end, the price of the naked car talked about 660,000.

Purchase tax + vehicle and vessel tax + compulsory insurance + commercial insurance + license, the landing price is 735,000.

Down payment of 190,0008.

When going through the loan procedures, Zhou Wen secretly laughed at himself in his heart: he had embarrassed all the system hosts.

Which of those system hosts is not driving a luxury car and living in a luxury house?

I bought a broken Audi and actually repaid the loan, and I lost my dead when I said it.

Just as Zhou Wen was about to sign, Zuo Mengmeng finally couldn't help but whisper: "Zhou Wen, do you really want to buy Q7?"

Zuo Mengmeng knew that Zhou Wen's income was quite high now, and the hospital had just rewarded him with a sum of money, so it was normal to buy an Audi.

But he didn't expect that he bought Q7, and the loan was close to 500,000.

Zhou Wen smiled: "This has to be signed, what do you say?"

"But...... There's no need to buy such a good one, just buy an A4. ”

"But I like Q7. ”

Zuo Mengmeng said speechlessly: "...... But you have to repay close to 40,000 loans a month, can you afford it?"

Zhou Wen smiled and nodded, "Of course, you can afford to ask this." ”

"But ......" Zuo Mengmeng originally wanted to persuade him, but seeing his resolute attitude, he didn't say anything more.

After signing the loan contract and paying the deposit, Zhou Wen doesn't have to worry about the rest.

The 4S store will help him get it.

Wait for a few days for the bank loan to be approved, come and pay the down payment and pick up the car and get the license plate.

Take advantage of this time to practice driving again.

......

Two o'clock in the afternoon.

Tanzhou Xiangya Hospital, Department of Infectious Diseases.

In the director's office, Cheng Yanqing was studying and analyzing his condition, and the nurse in the department knocked on the door and said, "Director, the antibacterial serum from Jiangzhou Hospital has arrived." ”

"Oh, yes. Cheng Yanqing immediately stood up when he heard the voice, "Let's go, go over and have a look." ”

When Cheng Yanqing arrived at the Department of Laboratory Medicine, more than a dozen experts from Xiangya Hospital had already come first.

They heard yesterday that Jiangzhou Hospital had provided antibody serum for two strains of Cryptococcus mutant.

So I rushed over to see the effect of the experiment.

The experimental procedure of antimicrobial serum is very simple, prepare a new cryptococcus slide, and then drip antibody serum into it to observe the reaction of cryptococcus.

Half an hour later, the results of the experiment came in.

What makes everyone excited is that the antibacterial serum of Cryptococcus mutans also has a very effective killing effect on Cryptococcus newans.

This is a remarkable find.

The experts and scholars on the scene were all excited and excited.

Cheng Yanqing immediately called Zhou Wen and told him about this astonishing discovery.

When Zhou Wen heard this, he was also pleasantly surprised.

If this news is released, it will definitely cause a shock in the global medical community.

Soon, a group of bigwigs in the WeChat group also knew.

@ Cheng Yanqing and Zhou Wen.

Jiang Feng Yuhuo: "@程砚青, what's the situation now?"

Kyoto Pan Renfeng: "@小周, come out and say a few words." ”

Gu Yunwen: "I just called them, and the two of them are on the phone." ”

Baiyi Shengxue: "Don't worry, they must be very busy now, wait for the evening." ”

“......”

Cheng Yanqing and Zhou Wen are indeed very busy.

I don't know how the news was revealed, so many people who know or don't know each other have called them for verification.

Accidentally curing a case of Cryptococcus mutans, although it is remarkable, is a special case, and there are people who are concerned, but not too many.

But if antimicrobial serum can cure all patients with Cryptococcus neoformans, that's a big deal.

Millions of AIDS patients die every year from meningitis caused by Cryptococcus neoformans.

If the antimicrobial serum of cryptococcosis is replicated, then China will have one more Nobel Prize winner in medicine.

"Director Lin, it's true...... Well, so further research is needed, and there is still a long way to go before it is truly eradicated. ”

Hanging up Lin Huaidong's phone, Zhou Wen held the phone and pondered.

Although the antibacterial serum of Cryptococcus mutans is also useful against Cryptococcus neoformans, it does not mean that Cryptococcus neoformans can be completely cured.

Because there is no antibody serum.

It is unrealistic to directly smoke Tao Cheng and Li Meiling's serum.

Just two people, how much serum can be extracted?

It's enough that people can provide some for medical research, and it's impossible to draw blood for you all the time.

So the only way to do this is to extract the serum cells and then replicate the cells, which is to say clones.

However, this technique is very difficult, because the content of antigenic B cells in serum is too low, and the normal is only 1/100,000.

After the isolation of B cells, the sensitivity and specificity of their sequence amplification and determination are also very high.

Even if the sequence is amplified and the antibody is expressed, the comprehensive effect of the antibody needs to be further identified, and it may not be able to catch up with the original antibody serum effect.

So don't think about it so much for now.

Just when Zhou Wen was thinking about these things, a system prompt suddenly sounded in his ears.

"......"

Zhou Wen said, opened the task and looked at it.

[Mission: Replicate antimicrobial cells.]

Description: The number of deaths caused by Cryptococcus neoformans is as high as one million every year, and curing it will be a great boost to your personal reputation and conducive to the development of biopharmaceuticals.

Requirements: Successful replication of cryptococcal antimicrobial cells.

Rewards: 30,000 subject experience, 30,000 points, one chance to open a case (Gold)】

Zhou Wen looked at the task requirements and rewards, and his heart was both greedy and helpless.

Antimicrobial cells are not so easy to replicate.

Just like the prion inactivation mission, he still doesn't even have the courage to experiment.

Because he knew it was too difficult.

This is not the same as the yeast system, where the main difficulty is in the details, so it is overwhelming.

Replicating antimicrobial cells is a real scientific research, just like the genetic modification of rice aphids, which requires cumulative experiments.

With his current knowledge reserves, it was too difficult.

So at present, the first task is to work hard to improve the subject level.

......

At 10 o'clock in the morning of the 19th, Zhou Wen, who was writing a paper in the office, received a call from Cheng Yanqing.

"In the morning, our hospital held a meeting to study and decide to establish the Cryptococcosis Research Center of Xiangya Hospital. ”

Zhou Wen smiled: "It's worthy of Nan Xiangya, your hospital leaders are so fast!"

Cheng Yanqing said with a smile: "In addition, our hospital plans to hire you as a senior consultant of the Cryptococcosis Research Center, what do you think?"

Zhou Wen laughed and said, "I can't ask for it......"

Just as the two were talking, in the office of the vice president of Jiangzhou Hospital, Pan Yingshao slapped the table and shouted: "Xiangya Hospital, it's a robber......"
