Chapter 231: Controversy

On top of the bookcase was a row of cabinets surrounded by glass. Inside were a few yellowed ancient books.

The warm yellow light shone on the book, emitting a faint and gentle glow, attracting people to reach out and touch it.

Guo Miao held her breath and looked at Heleness.

Neither of them spoke.

Heleness swiped the card in her hand on the verification device beside her. With a beep, the glass door slowly opened, and the ancient book appeared in front of them.

It was a precious ancient book from King's University in Fog City. Only some very rich people or outstanding graduates of the university were qualified to open it.

The two of them carefully took down the ancient book, put on gloves, and flipped through the book.

Guo Miao was deeply shocked. The moment she touched it, she felt a deep connection with the predecessors of the mathematics world, which shocked her soul.
