[Fantasy + System + Transmigration + Summoning + A Bunch of Other Things I Can't Even Name]
Volume One: The Swordbearer: With the three-foot sword in my hand, I right the world's injustices (This volume features a System. Don't read if you dislike that.)
Volume Two: The Spectator: Blades flash and swords clash, yet not a drop of blood stains my white robes (This volume features transmigration into a book. Don't read if you dislike that.)
Volume Three: The Summoner: I am the army, and the army is me (This volume features summoning. Don't read if you dislike that.)
Volume Four: The High Priest: I would trade my life for peace across the four seas. May the world be free of suffering and hardship (This volume may have a little adversity. Don't read if you dislike that.)
Volume Five: The Recluse: The rise and fall of the world is everyone's responsibility. What is one fleeting life worth? (The protagonist of this volume is female. Don't read if you dislike that.)
(The synopsis is limited in length, so I'll leave it here for now. Each volume has a different protagonist, but the main protagonist is Ying Changkong.)
