The promise that Fei Yu made was not some vulgar joke, rather it was the agreement that they had all made earlier - to help him complete the task of changing his name once they became stronger.
This kind of task would not be something an average player would spend time on, and they would not delve deep into understanding it.
After all, players usually decide on a name the moment they start the game.
And there is no time limit for name selection when a player logs into "Eternal Chivalry".
As long as you're patient, even if it takes a year, there's no problem at all.
There would be no cases where someone took the name that they had thought of, leading them to pick a random one in a flustered moment.
Exactly because of this, the demand for name-changing services among players isn't that high.
But exceptions always exist.
Tang Sanci was such an exception.
From the beginning, he was quite satisfied with his name. After all, it was an antique, and it was quite valuable, wasn't it?
