I didn't want to say it, but now it seems that I still have to say it.

First of all, from the conceptual point of view, when Tianya proposed the concept of "second evolution", the book had already been marked with the logo of hard science fiction; This is not a boast, the concept at least surpasses all existing science fiction ideas. That alone is enough to show that this book is hard science fiction. (See the "Dotting" chapter for details.) ）

Secondly, the book is, after all, a "web novel", it is not a thesis. Therefore, this book will use a "protagonist" as the starting point, and gradually 'fish out' the relevant stories, materials, etc., and gradually build a macro world.

It's impossible to eat a fat man in one bite, and it's impossible to write everything in one sitting.

Thirdly, science fiction itself is a field of "rhapsody", and it is unrealistic to have to make a frame for science fiction. Who would have thought of going to the moon when technology was just in its infancy? In the same way, we can't accurately predict the future now, so there is "science fiction".

Fourth, science fiction has a big hidden link - the background. This is something that fantasy fiction hardly needs to think about, but science fiction can never ignore it; Even if you don't write it, the author has to know it.

In the end, Tianya once again affirmed that this book is really hard science fiction. Of course, the author's ability is limited, but he will try his best to describe this "second evolution".

(Adjusted to the preface before the chapter is updated tomorrow, it will not affect the reading.) ）
