Ive read multiple like that, not all are transmigration tho and sometimes its not a grandpa or the vessel not a ring but the concept of a master in an object as cheat is very common ;)
"Other people get miraculous adventures during transmigration. They either get to be a skilled master or a wealthy young lord. Even the worst of them would have an old man in a ring to guide them to the right direction, but I don't seem to have anything."
