The civilizations of this world have all developed based on Brynhildr's common sense. So far, the places Lin Zheng and Brynhildr have passed through are still using the ancient rune script, and these are the

Ronhild was familiar with it, so it was not difficult to teach it.

However, it is obvious that the level prepared for them by the killer king Black Skull cannot be passed by knowing a few words. No, Lin Zheng has already obtained the adventurer-limited textbook prepared by Black Skull, and the literacy level is just

It is the most basic. Lin Zheng looked at the subjects, arithmetic, geometry, and basic physics, including some chemistry content. Although the content is relatively superficial, it is absolutely impossible for a group of illiterate people who have not received enlightenment education to master this knowledge.

It is not an easy task. I turned to the last textbook, which is about the organizational expression of language and basic behavioral norms. Your sister! Black Skeleton, that bastard, there are so many things, you are going to let me spend a lot of time.

How much time does it take to teach?!

What is even more painful for Lin Zheng is that in his eyes, these textbooks are naturally extremely backward. The expressions of arithmetic and geometry are extremely complicated because there are no Arabic numerals and algorithmic symbols. Then the problem is, these things, Lin

Zheng is basically certain that Brünnhilde has no hope and can only let him solve it. If he uses modern teaching methods to teach, the efficiency will definitely be greatly improved, but the problem is, what about the problems in the level?! Knowledge

No matter how high the level is, you can’t even understand the content of the question. You’re just kidding!

"Don't worry, leave it to me!"

Hearing this, Lin Zheng looked towards Brünnhilde and raised his eyebrows, "Then you tell me first, 1+2+3, and each subsequent number added is 1 larger than the previous one, until it reaches 20

, equal to how much?”

"Here, wait a minute, let me count!" After saying that, Brünnhilde hurriedly counted on her fingers, which made Lin Zheng dumbfounded for a while. You are still teaching mathematics at this level!

Obviously, just ten fingers were definitely not enough for Brünnhilde to count to 210. Seeing her eyes starting to form circles, Lin Zheng stepped forward and knocked her on the head, "Okay, let's just hand over the math aspect."
