Class, is a painful thing, whether it is 007 in high school, or water class in college, Chen doesn't like it, although the water class can lie on the back to play games, but sometimes it is very uncomfortable to not grab the position in the back.

In the same way, even in the other world, the way of teaching will not change, and there is a strange smell - physically, because the hygiene habits of people in this world are in a more subtle state, some devout believers of the god of light take two baths in their lives, is there a sense of déjà vu? Yes, this is a fight with medieval Europe.

Fortunately, there are still some normal people here, although it is impossible to wash it once a day, but at least three or four days can be soaked in water to clean it, so that the stench can only be covered up with perfume.

But one or two of them are very desperate! Chen Hao wants to wear a gas mask to class, the smell of feet, sweat, fox smell mixed with inferior perfume and the musty smell of the floor - this is a biological weapon! It is much stronger than mustard gas ** Salin Viex.

"Lao Chen, why are you in a daze with this mask?"

Franklin elbowed Chen Hao, who was fighting between heaven and man.

"Don't you think there's a terrible smell in this classroom?"

Chen Hao's gas mask was brought in the chariot, and this guy always carried it with him just in case.

"Oh, no, isn't it normal?"

Franklin also took a deep breath with his nose and sniffed, and Chen Hao was shocked when he saw it.

Maybe the olfactory organs of people in the two worlds are different...... Anyway, Chen can't stay anymore.

The professor on the stage talked about concepts that were enough to make modern high school students laugh, and as for books, what are you talking about? Don't you know that paper is very expensive? A book is worth dozens of taels of silver!

People in this era squatting in the pit either use toilet chips or directly use their hands, it feels terrifying to think about it, Chen Hao is not short of money anyway, this guy uses paper, and he was wasted by Erica.

In short, this is a miserable era, fortunately, as long as you have money, the quality of life can barely get by, if it is a few hundred years earlier, Chen Hao will go crazy directly.

If you think about it, beautiful girls wipe their butts with their hands or with wooden sticks after pooping. The reason for wearing perfume is that you can't take a shower, and the clothes are thick because you are afraid of the feces on your buttocks......

This is ancient times, even if there is magic, it is impossible to reach the living standard of modern humans, the white and pure costume actors in the TV series will never appear, they are still "burning pepper orchid" at that time, Ollie is combined with the pigsty, there is a big pit for about 100 people in the barracks, so Chen Hao is very curious about how Mulan joined the army for her father, isn't this squatting pit all together, is it possible that she wants to tell others that she will shrink into the abdomen?

There is also a more classic thing, the beautiful girl bathed in the lake under the moonlight, it is indeed a very good beauty, but it is easy to catch a cold, there is no aspirin penicillin in ancient times, and a serious bacterial infection can kill people.

And there is still Chinese medicine in Xiqi, although it is a bit nonsense, but Chinese medicine does not know why it is really useful, you can even not know the chemical composition of Chinese medicine, but it is useful to eat it.

There is a reason why Westerners don't recognize our traditional Chinese medicine, but they don't want to think about it, they have only experimented with Western medicine for hundreds of years, but our traditional Chinese medicine has been experimented with human beings for thousands of years, even if this is a bit empirical, but it is really useful.

At the end of the class, the professor on the stage threw out a "problem of the century" - calculating the distance traveled by a linear moving object with variable acceleration in a certain period of time.

"Students can think carefully about how this should be calculated. ”

With that, the professor was about to leave.

"Wait. ”

Chen Hao stopped him with an "Erkang hand".

"Can you not come to class after you solve it?"

"Yes, you can try it. ”

In the eyes of the professor, Chen Hao is a young man who is not self-sufficient, so naturally he is what he says.

This professor of knowledge base at the end of the Renaissance did not yet know what "Cartesian coordinates" and "definite integrals" were—advanced mathematics, which was compulsory in the first year of modern universities.

As for the Cartesian coordinates in junior high school, some of the more difficult places in the high school are credited.

Chen Hao walked up to the podium, dipped a quill pen, took out the paper he used to cover his buttocks, first wrote the definitions of differentiation and derivatives, and then directly determined the integral, a Newton-Leibniz......

OK, it's solved.

The professor couldn't read it.

Chen Hao could only spread his hands, threw the calculation draft to him, and then sat back in his position for a few moments, continuing to be in a daze.

"Did you solve it?"

Franklin's neck was about to break, and Chen Hao's gaze had changed from surprise to horror.

"Well, what's wrong?"

Chen Hao just wants to skip class and hang out elsewhere in the university, this thing is only interested in practical classes, and the rest is exempt, just like if you ask a 23rd century college student who can design a nuclear fusion furnace to go to a 21st century university, no one wants to listen to that kind of familiar stuff full of loopholes.

“...... Where did you come from? Your continent is so advanced?"

"Dude, we don't play the same system in two places, we don't know magic at all, and we can't cast spells, but we can do this. ”

Chen Hao pointed to the papyrus in the professor's hand, in his subconscious, he has always believed that science and technology are the only way out, and magic is nonsense, after all, people who come out of science are always superstitious about science.

"How do you survive without knowing magic, how do you fight monsters and demons?"

Franklin didn't understand it even more.

"With all due respect, those demonic beasts really don't have much combat power, and a thousand-person team on our side can slaughter them one-sidedly, and the demons don't know, but I think the final result will not change, and there is no physical body to resist the tyranny of machinery. ”

Although Franklin was willing to believe Chen Hao, he still felt that what he said was too outrageous, how could something so terrifying as a demon be slaughtered by someone who didn't know magic?

He didn't know that if the human beings on the earth were really in a hurry, it would be the Dongfeng Poplar militia coming together, and it would be unknown whether they could find the demon's dust at that time.

"Old Chen, I can't understand it, we hate machines, they don't work magically. ”

At the end, Franklin shook his head very directly and said what he thought.

"It's normal, each place has its own way of development, and we will meet sooner or later, so rest assured. ”

Chen Hao said that he understood, if it were another person who bragged to him about how awesome the magic was, he would have punched him a long time ago.
