Spacecraft Engineer

It is a science fiction novel that is relatively rare in Tomato. It is not a cool novel. The protagonist Rocks has no system or superpowers, but he is an academic master. He knows what he wants and continues to grow into a top engineer. However, I feel that the protagonist is also a little too worldly. He is not a perfect hero, but he is very realistic. This can be seen from his relationship with several female crew members and the artificial intelligence he created. I recommend it. The world view of the whole book is a bit big. I don't know if the author can hold on to it later. Come on.
