The Days of Cultivating Immortality and Arguing with the System

I really like this kind of fairy tales that focus on research and innovation. I have read two of them which left a deep impression on me, but then the protagonist stopped pursuing research and innovation and I stopped pursuing them. Do any book friends recommend similar books? [Sending my heart]

At first, I thought it was describing the difficulty of surviving in the world of immortality from a personal perspective. Later, I found out that it was about trying to face some rules of the world of immortality calmly. Now I understand that the heroine already has the aura of the protagonist that I don't know about, and the future is unknown. However, the heroine is already the most hidden one. Her cultivation is not high, she is very good at it, her magic weapon is awesome, and the system is powerful. But she doesn't know what the most important thing about this book is?

Very pretty. Especially the heroine's father. The character is quite fun.

It's good to read, the author makes it very comfortable and relaxing to read, and the protagonist's character is also rare.

I passed by and took a look. I finished it before I knew it. It's very interesting.

It's very interesting and fun to cultivate immortality

It's good-looking and the heroine is very smart.

It's good to watch, and the plot is not frustrating. More updates [please update]

Nice, very nice
