The Undying Mecha Emperor - Chapter 39 Bloodsucker

Lin Qi transmigrates to a world of immortals. In this world, there are sword immortals who can behead a person from a thousand miles away, peerless great demons who burn mountains and boil the seas, and ancient gods and devils who can divine the heavenly secrets.

They love gold, and they love silver. Even more so, they love gems that dazzle, like stars across the skies.
Firearms, jewelleries, and precious metals; A collector’s world will not be complete without antiques.
Storage auctions, old goods trade, re-estate sales and gold-digging. But the truth is, if one wants to make money, then the supreme way is through searching for the legendary treasures.
Holding the fort, there’s an ocelot, a wolf, and an Andes condor. At the side, there’s a loyal hound, an irascible ape, and an African honey badger. Who said that you can only rely on humans when treasure hunting?!
