"Who are you really?" Jacob finally spoke, wanting to buy time to decide what to do with Whiteness now.
After all, he can always expel Whiteness from the Infinite Space with his authority and even consider it at this moment, but when he thought about the gains, especially the method Whiteness used to find 'his' locations so soon, if he could somehow restrict Whiteness, he was hesitant.
Moreover, Jacob was already certain that Whiteness was beyond the ranks of Legendary Plains, meaning he was from either the Upper Plains or the Void and probably had information he desperately wanted, especially about his enemies.
That's why Jacob was unwilling to simply let Whiteness escape and still feel there was a chance he could deal with Whiteness within the Infinite Space if he used some of the abilities he had never used before.
