Ding Dong dong, the bell for the end of class rang, Hoshikawa Zhenli Huo Ran got up, and said in a crisp voice: "Get up." ”

The students stood up, bowed, and said, "Teacher, hard work. ”

Kurokawa Eishin nodded, casually pointed to a student in the front row, and helped carry the human anatomical model back, the pointed student had a bitter face, but he didn't dare to refuse, and got up honestly and carried the model that was half complete and half exposed.

As soon as the teacher left, the classroom immediately became noisy, and Kobayashi Yu turned around and said with great interest: "Muto, let's go to the toilet." ”

Muto Qing was a little speechless, isn't it just going to the toilet, you are doing the same as inviting a date, why are you so excited.

Strange to say, from the memory of the original owner, the students were very enthusiastic about going to the toilet with people with good relationships, and although the original owner did not have friends who were good enough to go to the toilet, they also saw many people go to the toilet together.

He didn't refuse, turned his head and asked, "Qihe, do you want to go?" ”

Qihe Zhengzhong lifted his golden hair, as if he was a swimmer who had just climbed out of the pool, handsome and compelling: "Although it is not my interest to go to the toilet with boys, since you said it, I will accompany you to it." ”

Xiao Linyou rolled his eyes and complained: "If you don't go with boys, do you still want to go to the toilet with girls." ”

He pretended to be deep and said: "Actually, I've only been there four or five times, it's not worth mentioning,"

This attitude makes Xiao Lin You inexplicably angry, I really want to beat up this winner in life, damn it, I don't want to be a base if I look so handsome, but I go to make girls, and let ordinary people live.

Muto Qing didn't care too much about this, and said lightly: "Okay, let's go." ”

The boys' and girls' toilets are separated, that is, they are not together, and down the stairs outside Class A, there is the boys' toilet, with a long sink outside the toilet and a long mirror placed there.

The three of them went downstairs and entered the men's restroom.

It is not connected to the public toilets outside, and the student toilets are cleaned by students in turn, so there will be no urinal out of the urinal casually, and there will be no problem of pulling on it and not flushing.

The cleanliness of the exterior alone is comparable to that of a five-star hotel.

When Qihe Zhengzhong walked out of the toilet, he saw a beautiful woman with long brown hair, his heart suddenly rose, and he didn't even bother to wash his hands, and stepped forward to greet him: "Yo, this beautiful princess, I don't know if it's ......."

"Huh?!" The long-haired beauty turned her head sideways, her azure eyes were as sharp as knives, just a glance, and that domineering aura had completely destroyed his lust.

Of course, there is another main reason, according to his eyesight honed over the years, this is clearly C, not D at all.

Bang! As he pondered, he was kicked in the abdomen with a sudden blow, and his back bent down like a lobster.

"I always feel that you guy is thinking about something very rude, and next time you dare to think about it, it won't be done with one kick," the bad girl said lightly, retracted her long legs, and turned to walk towards the women's bathroom.

Muto Qing, who came out, saw him holding the sink with one hand and covering his abdomen with the other, and wondered, "What are you doing here?" ”

Qihe Zhengzhong raised his head with a pale face and smiled: "Nothing. ”

People didn't want to say more, and Muto Qing wouldn't pursue it, so he stepped forward to turn on the faucet and wash his hands.

The three of them returned to the classroom, and after going to the toilet together, the relationship grew wonderfully, at least Nanagawa Masataka would not run to ask the big-breasted girl at every turn, but would stay in the seat, and talk to Kobayashi Yu, Muto Qing would occasionally echo a sentence or two, and most of the time he listened.

After a while, the bell rang, and the scattered students gathered in the classroom, sat back in their places, and waited for the chemistry teacher to arrive.

A little, a sloppy-looking person appeared at the door of the classroom, with messy hair like a bird's nest, a white coat, a beard like weeds that had not been cleaned up, and he didn't look like a teacher at all, more like a research maniac.

The squad leader shouted in a crisp voice: "Stand up!" ”

The students got up: "Hello teacher. ”

The teacher's expression at the head of the bird's nest was quite cold, as if he didn't care about this aspect of the matter, his eyelids rolled, and he said lightly: "Hello students, I am your chemistry teacher, Sanada Yasu." ”

With a simple introduction, Sanada Yasushi magically took out the alcohol lamp and the iron stand, and introduced himself: "Open your chemistry textbook, the first lesson we taught was the combustion experiment of potassium chlorate. ”

This is obviously a very self-oriented teacher, who doesn't care whether the students can keep up with their own thinking at all, just blindly says what they want to teach, and the teaching mode makes Muto Qing feel familiar for a long time, as if going back to a long time ago, when he listened to someone preach.

"Students, potassium chlorate is stable at room temperature, decomposes and releases oxygen above 400 °C, and can form an explosive mixture when mixed with reducing agents, organic matter, flammable substances such as sulfur, phosphorus or metal powders, etc., and can explode when heated sharply. Let's say I put sugar in it. ”

Sanada Yasu said as he carefully sprinkled a little sugar into the test tube, and when he rubbed it, orange flames erupted from the mouth of the test tube.

Muto Qing subconsciously grabbed the palm of his hand, and his pupils dilated, not that he was shocked that the gas and sugar were mixed and he breathed fire, but that he had just felt a pure fire from the flames that erupted.

Unlike the fire aura, if a cultivator inhales the fire without authorization, it will cause the physical body to be eroded, and after a long time, let alone cultivation, even his life will be lost.

However, this common sense was overturned three hundred years ago, when a peerless genius appeared in the Yuanyang Immortal Realm, who was rejected by those blessed land sects at first because of his ordinary qualifications, and that person was also ruthless, and he couldn't enter the cave heaven blessed land, so he looked for those fierce places where the fire was condensed.

After a long time, not only did that person not die, but instead cultivated an earth-shattering supernatural power, known as the Fire Demon Immortal King.

This time, he will escape into this world, that is, after killing the Fire Demon Immortal King, he was too seriously injured, and was rebelled by his subordinates, so he had to escape from the Yuanyang Immortal Realm.

Now, when he saw this fire, he suddenly had an idea in his heart that just such a small amount of potassium chlorate mixed with white sugar could produce fire. If it is tens or hundreds of times more, there will definitely be more fire.

Instead of going to great lengths to absorb the aura, it is better to absorb the fire sha, and in this way, it will be faster to cultivate.

He didn't believe that what the Fire Demon Immortal King's subordinates could do, he wouldn't be able to do.

Sanada Yasu raised his head, looked around at the students below and said, "Which of your classmates wants to come up and experiment?" ”

Muto Qing stood up suddenly, her delicate face was full of excitement, and her eyes were fanatical: "Teacher, please let me try!" ”

"Okay, this classmate, you come up and try it," Sanada Yasu felt the heat in his heart, and his heart was equally happy.

As a research freak, it's natural to appreciate students who have a fanatical mindset about chemistry.
