Can you recommend a novel about interstellar warfare?

A novel I read before 2005
I don't remember much
It's about how many years the empire in the universe withstands an attack
The main character is a man who likes to read books.(1. The character is the father, who should be the duke, and the two brothers died when the enemy attacked that year. Then the main character is the only heir of a family.)
2. The protagonist likes to read books The place where he read was very big. The book mentioned that he often read and forgot to eat. Only a maid who took care of him could find him.
3. The enemy's attack seems to have a time limit. The enemy should be a threat in the abyss of the universe formed by several clans. The reason for the war is to capture excellent genes
4. Basically, it was a large-scale battle. In the end, the enemy heroine retreated in order to capture the male protagonist's warship.
How did you get in? I forgot that when the hero's bridge was broken through, the hero let the other people on the bridge into the escape capsule room, then broke the door and let out the escape capsule. He was still there pretending to be a very weak person, telling the enemy that the commander of the warship had run out in the escape capsule. The enemy left without much time to chase after the escape capsule.
Finally, the heroine knew that the commander who had been fighting with her was that cowardly person, but fortunately, she took a few strands of the protagonist's hair back.
Then, the technicians would say what genes could not be fused and so on
5. The hero is rewarded for his victory.
But the male protagonist only wants the right to enter the secret library of the palace to read books or something
is over
The description of the protagonist's planet should be that only people with titles can live on the planet
Finally, when the heroine said that the male protagonist should wash his neck and so on, it should be the next attack in many years.
He mentioned that the enemy was guarding the abyss
But the work didn't say what was threatening them.
There shouldn't be much paper left in that era. It vaguely mentioned Earth, but it wasn't clear.
It should be that online novels had just started to rise, and the period when online novels were turned into physical books by the publishing companies was not too long.
It seems that I can't find it

Answer 1

😋I recommend the book " Star Wars: My Warship Can Transform " to you. It tells the story of Qi Yiming piloting a super warship that can transform at any time and re-enter the galaxy. The warship can change its combat form according to the battlefield situation. It is a science fiction novel about the world of giant warships and cannons. I hope you will like this fairy's recommendation.😗
