The Hitchhiker's Guide to the Stars of the Living Dead

In the vast universe, you can see fleets that cover the sky and magnificent giant structures, which are the crystallization of technology; similarly, on some planets, iron and fire are still the mainstream, and in some galaxies, magic and technology go hand in hand... If you are interested, have enough life and a ship from the past, and want to embark on a romantic space voyage, but suffer from lack of experience, worry about accidentally eating some strange creatures, and violating some trivial alien customs, which will cause unpleasantness, then this small guide may help you avoid these problems to a certain extent. I wish you a pleasant journey in advance.
