Transmigrated to Another World as a Traveling Merchant

In another world, merchants who wander through every corner of the land are known as Traveling Merchants. They trade in human time, lifespans, and emotions. The head of the greatest Traveling Merchant family in the world is suddenly wiped out, but no one knows that the family's only son witnessed the massacre with his own eyes. On the very day his family was slaughtered, the sole heir gains a Revenge System. Soon afterward, his unscrupulous relatives dump him in an orphanage. When he grows up, he uses the System-granted power of teleportation to travel the world, while searching for the culprits who once dared to kill and rob his family.
