The First Rule of Time Travel: Learn Mathematics, Physics and Chemistry Well

I feel like the heroine is very nice [laughs awkwardly] She's not a holy mother, and she won't give supplies to others easily, but when she meets a very upright soldier who has also traveled through time, she will give him a truck full of stuff without hesitation. This place is really awesome, okay?

It would be perfect if the heroine went to the world of female supremacy. It is really not suitable in this ancient time. She looks good in this setting, but the heroine was not innocent before time travel. Please pay attention to the two cleansers ⚠️Because I have vomited blood and want to quit. The male protagonist does not respond to me. It is embarrassing for a woman. It is normal in modern times, but it was not the case in ancient times. It is very serious. Well, the status is still high. The male protagonist has never had other women.

Unlike other books, it talks about collecting supplies, but nothing was used in ancient times. I quite like this type of book.

Sisters, hurry up! It's not a loss if you invest in shares.

Anyone who likes Yuan Chengcheng, meet here! This person is also portrayed so well [blowing kiss]

Not bad, come on, author!

Very pretty, very good

I finally know it. If you learn mathematics, physics and chemistry well, you won't be afraid of time travel [laughing]

It's great, I like it very much, the author should keep up the good work

It looked good, but it ended too quickly.

Not bad, come on ୧( ⁼̴̶̤̀ω⁼̴̶̤́ )૭

It's awesome, it's really awesome. I think this book is the most attractive of this type I've ever read, but it's really short.

Okay, pretty good-looking

The subject matter is novel and the language is interesting
