As the only boss in the quest, General Yang gave a lot of loot. Aside from the Silver Dragon Spear that Happy snatched from him, he had also gained a grade two masterpiece armor set.
[Silver Aquatic Dragon Armor (Grade two masterpiece):
[Increases defense by 600, increases Affinity by 10, increases Body Movement by 10, increases dodge rate by 10%.
[Once you gain all five major components, you can assemble the full set!
[Your overall defense will increase by 100, dodge rate by 40%, all your attributes by 20, movement speed by 10%, and attack speed by 10%.]
The attributes at the end meant that Silver Aquatic Dragon Set would not give the user the feeling that they would be dragged down by the armor. Instead, it would increase the users strength and speed by a lot. All of the attributes were really great.
When he saw the annotations, Happy knew that he had not done the quest in vain!
