After discovering that the "Harbinger of Death" was a treasure, Su Lun spent the entire night studying its additional functions.
He thought that even in the necromantic realm of another dimension, such a "mythical species" creature would be very rare.
Fearing he might not be able to summon it again, Su Lun coaxed and deceived, planning to sign a Blood Covenant.
The crow seemed not to mind, happily agreeing after consuming two pieces of rotting flesh.
Although they couldn't communicate directly, as a contracted creature, they could simply share thoughts.
The intelligence of crows is already high, but this "Harbinger of Death" was clearly much smarter than the average crow.
Moreover, Su Lun had also gleaned some experience in raising crows, making their communication relatively smooth.
Soon, he figured out the other two abilities of the bird — "resurrection" and "shared vision."
