Infinite Reincarnation: My Swap with the War God

Su Ruan endured one hundred and twenty-seven cycles of reincarnation. As a team support, she risked her life to save others every time, only to be repeatedly sacrificed by her teammates and die in the dungeons. Ling Xiao, recognized as the War God of the infinite space, charged into battle to protect his companions and earned great merits, but was ultimately betrayed and killed by the guilds that feared him. The two fell together at the moment of the dungeon's destruction, accidentally triggering a rare space-time rollback privilege, and returned to the rest cabin with all their reincarnation memories. Seeing through the malice of human hearts, they decided to swap their fates. Su Ruan gave up her support role, broke into high-risk dungeons, and relied on her hundred cycles of memories to use the dungeon's dangers to settle scores with the ambitious reincarnators. Ling Xiao no longer charged into battle, but lurked in the main city to stir up power struggles among the major guilds, activating the dusty punishment archives to make the wicked pay. Dungeons were filled with eerie artifacts, and the main city was fraught with treacherous hearts. The old guilds sensed the threat and set up killing traps to hunt the two, who gradually discovered that behind their repeated tragic deaths lay the hidden manipulation of the space itself. While clearing dungeons and overturning the main city's dark secrets, the duo joined forces to declare war on the cruel chess game of the infinite space! — Description from novelcodex.org
