Obviously, there can't be such a good thing, otherwise, the 7D printing pen will not sell out in the mall?

Cheng Xixi continued to explain: "The printed fruits and vegetables contain highly toxic fruit acids, and if the printed food is not professionally compressed and detoxified, it will also lead to poisoning. ”

Fruit acidosis......

Li Lechen has indeed seen the tragic scene of fruit acid poisoning, the key is that after detoxification, it is not much better, and he lost dozens of pounds almost instantly.

However, the "Xiao Ming Get Out" has learned to use the method of pickling cucumbers to detoxify 7D printed fruits, and it seems that it has been successfully put on the shelves and sold a lot.

But......

"Don't you need any consumables for 7D printing? Just such a pen, where do the consumables come from?" asked Li Lechen.

"In the case of consumables, the pen will automatically search for the periphery, so to distinguish whether the printed thing is used or eaten, the selected consumables will be distinguished. ”

In this way, almost everything is understood.

But I still don't understand one thing: "Then if the materials I provide are not poisonous, the printed food should not be poisonous, right?"

"This ......"

Cheng Xixi couldn't answer this point. She hasn't bought a 7D printing pen, and this thing is actually not cheap, 500 sunshine coins a piece. Second, it doesn't make sense to buy a printing pen, and it's not a child, so it's a play.

In theory, though, it seems so.

But that's not right!

"The official statement is that the food produced through 7D printing technology must have toxins, and it cannot be eaten without official detoxification. Cheng Xixi said, "And the fact is that even if someone buys 7D printed food directly, it will be sent to a professional detoxification company for processing before eating." ”

It's even stranger to say that.

Studied but cannot comprehend.

Cheng Xixi can't say it, after all, as a poor person in the quarantine area, she has too few things to come into contact with, and she hasn't even visited the mall a few times.

Theoretically, as long as the consumables are not toxic, the finished product will not be toxic, so why is it not toxic to drink water, but if the fruit is not completely dehydrated, it will cause fruit acidosis?

Or, the toxins are present throughout the 7D printing process.

But how can this kind of technical problem not be overcome?

It should be able to conquer it, right?

But the fact is that the official has always emphasized that 7D printed food is highly toxic, and 7D printed food is indeed highly toxic, because there are always one or two cases of poisoning due to accidental consumption of 7D printed and undetoxified food every year.

Li Lechen also thought about this question, but he didn't analyze it in depth, after all, what will happen after 2,000 years, the government after 2,000 years, and the brain hole after 2,000 years, who knows?

was about to try this 7D printing pen, and a barrage jumped out [Reminder: In order to maintain the healthy development of the platform, it is strictly forbidden to have one-on-one interaction for too long, and the one-on-one chat between "Chasing the Wind Boy" and "Chivalrous Girl" will be forcibly closed after three minutes]

Huh? And this?!

Even now, speech and behavior are quite free, as long as men and women don't gather in a crowd, no matter how men and women do it, they won't be checked for water meters.

How is it that after 2,000 years, even a little more private communication has been warned?

What has happened in these two thousand years?

It doesn't just seem that the environment has gotten worse......

Obviously, Cheng Xixi also received this reminder.

Although it is the first time that this situation has been encountered, it is true that the platform's intervention is everywhere, so Cheng Xixi is not surprised.

"Have you finished the exam? Do you still have an exam at night?" Cheng Xixi asked, "It should be that after this disconnection, today, maybe we won't be able to communicate in private like this in the past few days." ”

"It's politics at night, I can handle it. Li Lechen responded.

Of course, politics keeps pace with the times, and Li Lechen was not prepared to find Cheng Xixi to be a gunman from the beginning. Just like modern people, even if they have Baidu in their heads, they may not be able to answer the political questions of 2,000 years ago.

Although I don't understand why a live broadcast platform is forbidden to communicate more privately, it is not surprising that compared to my own school, it is not surprising that eye contact between male and female students can be banned for more than three seconds.

The taboos of each era are different, if it was put two thousand years ago, Li Lechen's age would have had several children.

Sure enough, Cheng Xixi soon dropped the line.

Li Lechen returned his attention to the 7D printing pen in his hand.

With Cheng Xixi's previous explanation, the operation is much more purposeful.

No. 1 refill, something for printing......

Li Lechen looked up, and there was a slip of textbooks in front of the table. Don't copy this to death.

Looking up again, there is the lectern and the blackboard, and the two invigilators are not suitable for copying......

"Smack!"

Suddenly, a crisp sound of glass breaking attracted the attention of Li Lechen and even most of the candidates.

"I'm sorry, I'm sorry, everybody continues to take the exam. ”

It was the female invigilator who opened her mouth to apologize. She had just fanned the wind and accidentally shattered her glass.

It's just that the teacher's glass is broken, and everyone looks up, and then lowers their heads and continues to work on the question.

Science and mathematics are the same, in most cases, time is not enough, and the situation is frequent, so it must be rushed.

Seeing this, the male invigilator quickly brought a broom and dustpan to help the female invigilator remove the glass shards on the ground, and poured them into the large trash can at the back of the classroom.

Others didn't care about this little episode, but Li Lechen thought about it a little more: Otherwise, just print a cup.

That's right, this is the most harmless, and it doesn't matter whether it is CD or not.

The most important thing is that the cup is easy to draw, and you don't need any painting skills, just a basic cylindrical type.

So the histogram of the structure flashed through my mind, pressed the printing pen, came out with the so-called No. 1 refill, and drew it on scratch paper.

Just simply drew a few lines, and even crookedly, but I didn't expect a line of text to jump out [the printer pen detected that you tried to print a cup, do you want to make a smart match?]

Huh? There's such a thing as smart matching? That has to be chosen!

[A total of 17 eligible masters have been detected near you, please select the required master.] Masters can be superimposed and modified.

Along with this line of text, there is also a string of pictures, all of the same color of the cup. Yes...... Lin Kun's cup, Wu Qunfang's cup, Luo Li's cup...... Well, there are a dozen more cups that don't know who.

looked sideways at Lin Kun, who was working hard to write.

Then choose Lin Kun's cup.

[Does it automatically search for consumables?]

Search it automatically, if you want to search manually, Li Lechen really can't.

After that, the printer pen really searched for several consumables to choose from, including a lot of zero points in the air, the whole piece on the ground, the blackboard was also covered with a thin layer of consumables, and even in the trash can.

These "consumables" are circled for Li Lechen to choose to print.
