[Do you have any knowledge about human physiology and hygiene in your intelligent knowledge base?] Li Lechen suddenly had an idea, turned a corner and asked.

[You mean the structure of the human body?]

[For example, the reproductive system]

[Yes, the reproductive system is the system in the body of an organism that produces germ cells to reproduce offspring. The human reproductive system, male including yin, **, epididymis, **, prostate, rice green fluid, bulbourethral gland, etc. ......]

【Wait a minute!】

Li Lechen hurriedly interrupted Cheng Xixi.

It's too written, and it's going to be pornographic.

This kind of should be vaguely said eggs, chickens, leukomycin and the like.

So I can't continue to talk about it, and then the girl's reproductive system, Li Lechen feels that he will react when he reads the text.

No way, 18 years old.

[You said that you came out of the gene pool, so is there anyone who was born through natural means?] Li Lechen asked.

In fact, what he wanted to know was not this, but he was pretending to be pure and seducing.

[Are you trying to ask about natural reproduction?]

[That's pretty much it]

[Since the environment began to deteriorate a thousand years ago, and suddenly worsened four hundred years ago, human beings have been unable to reproduce naturally]

[Can that man still duang?]

Li Lechen asked subconsciously.

The inability to reproduce naturally only means that the sperm quality is too poor to conceive, right? According to the increasing trend of hospitals treating infertility, it seems that this human being is really likely to be sterilized after thousands of years.

But you can't stop getting up, right?

It's a pity that Cheng Xixi is not a man, and she doesn't have the word duang in her intellectual knowledge base, so she is completely at a loss.

【......】

[It's bo, sex, have a relationship, make people, make love...... it!】

Li Lechen tried his best to use the words in writing, but the more he thought about it, the more embarrassed he felt, and if he went down, he would definitely be involved in pornography. However, the mind is very pure, and this is talking about physical hygiene. And it's a major event for the future of humanity.

If it's all about pornography, why don't the textbooks be blocked?

Cheng Xixi is still at a loss [......]

The smart assistant is also [......]

Li Lechen fell into deep thought.

In the future, 2,000 years from now, will humanity be on the verge of extinction? There are almost no animals, plants have become rare, ultraviolet rays can raise the temperature of objects to hundreds of degrees in a few seconds, and even the most basic reproduction of human beings has problems.

Technology is powerless in the face of nature.

[Dear, did I say something wrong?]

Cheng Xixi saw that Li Lechen didn't respond for several minutes, and couldn't help asking.

[That...... I want to upgrade as soon as possible, do you have any good suggestions?]

Li Lechen returned to the right path and suddenly became serious.

He didn't mean to divert the topic, he felt that he should work harder to escalate. The higher you level up, the more you can learn about that world in the future, and there should be only benefits for the present and the future.

Upgrading this kind of thing, basically it doesn't make much sense to reach level 20 or above, it almost includes 90% of the functions on the platform, and then it goes up, the functions are very high-end, and it is not something that residents in quarantine areas like Cheng Xixi can use.

After that, Xixi still answered Li Lechen's question very seriously.

Because of her character, coming out of the gene pool is like that.

[The fastest way is, of course, to spend and tip. And you can't open the mall now, so you can only tip. Do you really want to level up sooner?]

[Of course, I can't wait for it right away!]

[How many points are you missing?]

[less than 2,000]

[Then you wait a while to go on the live broadcast]

Well?

Li Lechen thought that Cheng Xixi was going to tell him that there was any way to quickly obtain Sunshine Coins or upgrade quickly, otherwise, it would be good to provide more information.

However, Cheng Xixi actually went offline.

What's the situation?

After hesitating for a while, he re-entered the live broadcast room.

"Brush—"

[Level 19 user "Chivalrous Girl" rewards the anchor with 1,000,000 sunshine coins]

As soon as he entered the live broadcast room, Li Lechen saw such an amazing tipping prompt. The key is that it was Cheng Xixi who rewarded him with one million.

How is this possible?!

Wasn't she too poor to pay the cabin rent two days ago, and might be expelled to a polluted area? Could it be that Cheng Xixi is the legendary begging for a son with a lot of money, oh no, pretending to be poor and selling poor Bai Fumei?

Ignoring all the exclamations in the live broadcast room, Li Lechen hurriedly retreated again and contacted Cheng Xixi [Where did you get a million?!]

【Borrowed】

[Borrowed?]

[Yes, borrow from the bank, so that you have a million, and you can upgrade after consumption]

After speaking, Cheng Xixi suddenly felt that she should explain, otherwise she would be misunderstood and sold poor before [because you gave me a reward of 1 million last time, I paid 700,000 taxes, and I have a credit limit of 700,000, and I can borrow up to 1.4 million]

I see!

[Then how can I give it back to you?]

Li Lechen didn't expect to go to Cheng Xixi's live broadcast room to reward her, but the problem was that she couldn't find it. This feeling of not being able to repay the money owed to someone will make you very afraid of making a promise.

Cheng Xixi didn't think so[I chose to pay in installments for a hundred years, and I only need to pay 1,000 yuan per month after interest]

[Then I must pay you back]

[Uh-huh!]

Of course, Cheng Xixi is not worried that Li Lechen will not pay her back, at least she still has more than 300,000 yuan in her hands now, which is enough to pay off for more than 20 years.

"There are still 15 minutes left until the end of the exam. ”

Zheng Fangxing's voice suddenly came, interrupting Li Lechen and Cheng Xixi's chat.

Then, the classroom became noisy, with all kinds of sparse sounds of turning over test papers, and even muttering, complaining that there was too little time, and that it was disturbed just now.

Especially the boy who was confiscated from the electronic watch at the beginning, looked up to the sky and sighed: What about telling yourself the time every fifteen minutes? Why did you only report the time once in the first half an hour, and the second time was only 15 minutes before the end of the exam?!

But no matter what, when the time comes, it will be closed.

Li Lechen finally decided to write only one "solution" on the last big question, the full score is too much, and 130 points is already very high.

......

......

During the lunch break, Li Lechen carried the one million sunshine coins that Cheng Xixi gave him through a loan, and was ready to find a live broadcast room to give a reward.

Through accurate calculation, he gave out 100 red envelopes in this wave of rewards, and he received 30 red envelopes back, which was enough to upgrade.

You can have both upgrades and red envelopes, and that's really great.

But to whom is this million?

It would be great if you could brush up on Cheng Xixi's live broadcast room.

It's a pity that I have looked up and down more than a dozen times, but I still haven't been able to brush it.

[The "Food World" of "Xiao Ming Get Out" is being broadcast live, and the anchor will taste unofficial detoxified food, whether it is a surprise or a fright, come in and take a look!]

A banner ad was pulled leisurely, and it was pulled three times in a row.

I was worried about where to go to reward, so I decisively clicked on the advertisement to enter the "food world".

In the live broadcast room, Guo Xiaoming was smiling at the fruits and vegetables on the cooking table at this time.

For 3,000 Sunshine Coins, he purchased 30,000 pieces of "Banner Rotation Advertising Attention" business from "Joy Brush Adult".

This kind of publicity method is more eye-catching and effective than brushing the barrage in the live broadcast room, regardless of whether the other party is live or not. Although it is not as good as the kind of advertising that can receive Sunshine Coins, it is the most cost-effective.

Of course, what content is broadcast directly affects whether the advertisement is effective or not.

Sure enough, when it comes to unofficial detoxification, and it is still to be tasted, most of the people who see the advertisement are attracted to it.
