The two choices given by the side quest didn't seem favorable to Han Dong.
If he directly kills the Beast species,
he can only obtain the "Damaged Heart of the Giant Beast". Without special preservation methods, it is impossible to bring it back to the City Wall, and it would perish even before leaving the cave.
The team can only soak their badges in the heart's blood and claim the high reward for killing the Beast species after returning to the city.
As for some materials from the Giant Beast's body, they might be useful, but not significant.
If he chooses the healing approach,
he might receive a good reward (perhaps the Giant Beast would gift a piece of the horn), and the exploration later could get the Giant Beast's help.
This reward seems not bad either.
