After seeing off the Great Lion, Xi Wei turned towards the Players who had finally blown up the Marsh Drake's head.
While the Marsh Drake was related to the Marsh Hydra, it didn't possess the Hydra's survivability to grow two more heads when one was cut off.
Therefore, it was absolutely dead after it had its head blown up.
Naturally, Xi Wei was not going to be stingy whenever the Players offered him a Wild Boss that would never appear again after one battle, which also supplies him considerable divine energy.
Hence, he plucked out the heartstrings of the human-faced fish monsters' corpses that almost numbered a hundred, refining and tempering them into sturdy bowstrings. Then, he extracted the Barren Giants to make the body of the bow, along with some bone-powder from Rotten Bones' corpse as a string notch imbued with divine power.
