As for the purpose, that was too easy to guess.
Years ago, Song Chi had proactively brought out the Ten Thousand Year Dragon Blood Fruit—an artifact that extends lifespan—as a member of the Blue Blood Clan. Following that, Goblin Luke had sought him out countless times, eager to purchase the top-rank Dragon Blood Fruit.
However, the items Luke offered repeatedly failed to satisfy Song Chi. Only once did Luke manage to trade five strands of Fourth Rank Floating Land Origin for a single fruit.
That fruit, it seemed, hadn't even ended up in Luke's hands but had instead been consumed by a Fourth Rank Goblin Elder ancestor from the Viscount's Mansion that Luke served.
And it was precisely due to the ancestor's firsthand verification of the Ten Thousand Year Dragon Blood Fruit's effect that Goblin Luke became even more fanatical. Since then, almost every time a trade opened, he would come over to haggle incessantly, frustrating Song Chi no end.
