Chapter 155 Accumulated Contradictions

The most environmentally sensitive member of the entire research group, Liu Chenfeng, noticed Hanna suddenly became quiet.

It was a very obvious feeling.

Hanna used to create some break time, like afternoon tea.

Back when Chen Yiwen was still in the research group, they would often sit together and chat about this and that.

He occasionally joined them, and had personally witnessed the whole process of Hanna's evolution from a stuttering Chinese that mixed up subject, verb, and object to fluently expressing herself in Chinese.

But after that day, Hanna even gave up her daily afternoon tea.

Because several books had appeared on her desk.

Michael Atiyah's "Introduction to Commutative Algebra," P. do Carmo's "Differential Geometry of Curves and Surfaces," and others.

Many foreign mathematics works.

This made Liu Chenfeng feel quite envious.
