The Nightmare Puppet shuttles through the deep space, capable of crossing distances a hundred times what normal flight could manage—it's truly a travel miracle. The only pity is that deep space is utterly void, making it difficult to know where one has ended up.

Tang Yu gave it to the First Comer's first customer.
According to the instructions on the 'Summoning Scroll,' normally, to increase the success rate of summoning, the person possessing the scroll would choose to join hands with other customers, gathering enough 'currency' to summon a dragon... cough, a mysterious merchant.
If the 'currency's' value is too low, Tang Yu could only apologize, as he could not let the Nightmare make the long journey for nothing.
