Eric and those of the Slytherin Snake Sect decided to 'relax' for a night or two, before departing.
It's not like Eric and the others were amazed by the Royal Palace and wanted to stay, or that they liked the welcoming receiving.
No, they wanted to return back to the Sect as soon as possible, but they couldn't!
With the way the event unfolded and with how things were prepared to happen in the broken scheme, Eric could tell that the Royal Family and the others wanted to deal with them on the way back.
Leaving now would make things worse, as not only would the other party try to kidnap them, but the responsibility wouldn't even lie with them.
While a truly strong and powerful man wouldn't care whether what he did was justified or not, the King and the Sects couldn't do it.
After all, the identity of the Sect Mistress was slightly dangerous, and if that weren't all, the Kingdom couldn't have a direct confrontation with the Slytherin Snake Sect right now.
