"Between Leopard and Snake, have you made up your mind?"
Paskha tried to communicate with Drake, but the snake only told him either was beneficial for him with different results. Suppose Drake eats the pill core of Leopard. In that case, he will get an unbeatable level of agility since Leopard has high-speed skills, very suitable for soul masters who like to run away in the face of strong enemies.
Leopard was tough to kill; even the Great Master could only injure it but couldn't chase it if it managed to escape. Only Immortal Masters who have more extraordinary speed abilities than the beasts, then one could capture it.
On the other hand, if Drake swallowed the pill core of the flying snake, Drake could fly without using mana. And there was a possibility that the result of the first evolution was that the snake would also have a pair of wings.
So, either way, it was a considerable benefit for Drake.
