After Xander spoke, all the elders started hurriedly discussing amongst themselves.
They can't outrightly ban Xander from marrying Tang Yue even though it stood against everything they believed in.
And without the Emperor himself intervening, it would also be difficult to stop Xander from doing what he pleased.
He might be bound to their words and unable to marry Tang Yue publicly for now, but if they had powerful and strong children down the line, then they would be inevitably forced to accept them into the royal bloodline.
At that time they would have no other option but to accept the spirit beast as well.
But surprising everyone, Xander himself had offered a solution to their weird predicament.
If the snake were to disguise herself and travel to the dwarven lands, then they might be able to silently kill her off there.
If she by chance learns their technique, then it's even better.
