In the future, when Ren is 30, he has married everyone and each wife has given birth to a child for Ren, the story will focus on the fourth person, Nano's son, Aijou Yogiri, who is currently 15 years old
Since birth, Yogiri has been seen as a magnet of misfortune, or rather misfortune is him, Murphy's law is the most accurate thing to say about him, except for spreading misfortune, he is extremely lucky, realizing the potential danger, Ren decided to let him study at home to avoid accidentally causing harm to people around him, his tutor is his mother, Former Excellent Student Nano
-Nano: For example, what is the largest and smallest value of y = 2sin 4x + 5?
Yogiri: hmm,
When sin4x x = 1 - 1 < sin 4x < 1 - 3 < 2sin 4x + 5 < 7 - 2 < 2sin 4x < 2
4x = pi / 2 + k2pi = x = pi / 8 + k*pi / 2 When sin4x x = 1
4x = (- pi) / 2 + k2pi =>x=- pi/8+k pi/2
-Nano: yes, good job
Suddenly a call interrupted, it was kusuri
-kusuri: Nano, come help me, I was so foolish and now it's broken, I'll come, nanoda
-Nano: I'll come right away, estimated time 2 minutes 30 seconds 1.5 seconds
-Kusuri: oh save me, I love you so much, moa moa nanoda
-Nano: kiss on the phone is ineffective, wait for me to come over then if you like then kiss
Nano quickly packed up and left
-Nano: yogiri, mom left the problem under the desk, while waiting for mom to come back, take it out and do it temporarily, mom will check it later
yogiri: yes, mom, be careful
In the lab
-kusuri: kusuri accidentally messed everything up, worse is that out of these hundreds of chemical formulas, only 1 is correct, and that pot like the meat pot is a bomb that can only be neutralized with that formula, just 1 wrong formula and the whole place will explode! nanoda
-Nano: can't you create it yourself? Or at least with the right formula? -Kusuri: If that's the case, I wouldn't have bothered you. The problem is that if I followed the original, I myself admitted that I sometimes create things randomly without even knowing what I created. Besides, I'm a chemistry genius, not a chemistry machine. How can I remember all of this? Please help me nanoda
-Nano: Wait for me 2 minutes
After reading and remembering everything, Nano tried to simulate the cases if she combined the formulas into that dark meat pot (WMI-working memory index)
-Nano: The correct formula is
3C2H4+4H2O+2KMnO42KOH+2MnO2+3C2H4(OH)2
Kusuri took a chance and poured it in
-kusuri: That's right, yay! Thank you very much nanoda
Another call, this time from Hahari
-Hahari: Hello, my old class is planning to have a 2-day-2-night trip tomorrow, the teacher invited the boy to come along, because he rarely leaves the house, okay?
-Nano: I think it's good to let the boy go out and explore, anyway, just studying and staying at home is boring, so where will we go this time?
-Hahari: It's Akita prefecture (there's a real prefecture), 677.9 km, it will take 8 hours and 22 minutes to get there
-Nano: thank you, I'll call him back
After calling Yogiri, Ren and the girls are helping Yogiri pack his things
-Sekkusu: remember to bring condo- hihi
-Karane: oh my god. Did anyone let their son bring that things?!
-Saiki: remember to bring cough medicine
-Ren: remember, always protect everyone and yourself
-Eira: if anything dangerous happens, just shoot it right away
After getting ready, Nano took Yogiri to school
Going to school for the first time, he felt a little excited and interested
