Chapitre 847: The Adorable Pair of Brothers

Little Yichen felt that, with merely a gust of the wind, Youyou already neatly filled in all the answers and threw the arithmetic book at him. "I'm done!"

"You… So fast?"

He could not believe it.

The younger boy replied matter-of-factly. "Of course, these problems are too easy to solve."

His eyes went blank for a while before he hurriedly flipped through the book to check if his brother had done a slip-shod work just to fill in the answers.

However, after randomly selecting the solutions to a few math problems and struggling to calculate them for a bit, each was actually correct!

For a moment, he found it even harder to believe and only thought that his younger brother's calculation speed was simply unimaginable!

How did he do it?

His brother calculated everything in such a short time!

Little Yichen then handed over the English book.

There were still a few incomplete translations left.
