Teachings of Old

Teachings of old is a secret discovery in the Llevigar Plains, located at River Sage near Bucie.

Fisherman
To begin the discovery, speak to the fisherman inside his house. It is located just north of Bucie along the river.

Dialogue:
 * Fisherman: Why is cooking so boring and difficult?
 * Fisherman: I should do something abou-
 * Fisherman: Who the heck are you? Why did you just break into my house?
 * Fisherman: A-Are you… CHALLENGING ME!!?? Into a fishing competition!?
 * Fisherman: No one can win ME in a fishing competition!
 * Fisherman: You buffoon! Get yourself a fishing rod too and we'll settle this outside!!

Grab a fishing rod from the shelf and follow the fisherman outside to continue.

Dialogue:
 * Fisherman: You can have that slimy old rock, while I take all the fishies here, heh.
 * Fisherman: Can you catch at least [8 Fish] and beat my score? Just don't catch the pufferfish or I'll minus it off!
 * Fisherman: Ahaa! And so we begin…

To advance in the discovery, it is required to catch at least 8 fish. Should you catch less than 8 fish, speak to the fisherman again inside his house to try again.

Dialogue:
 * Fisherman: Huh, did you finish already? Ahaa! Let's see then…
 * Fisherman: Ahhah, I can see that you haven't managed to beat me.
 * Fisherman: Whatever. You lost, and nobody can beat me anyways!

If you catch 8 or more fish, you receive a Prismarine Gadget

Dialogue:
 * Fisherman: Huh, did you finish already? Ahaa! Let's see then…
 * Fisherman: What!? You actually managed to fish eight or more fish? And I only got seven! How pitiful of me…
 * Fisherman: Man, you reallly won me. I can't believe it!
 * Fisherman: Hold on, what is this? In the river? It looks like...
 * Fisherman: That thing sure does look weird... Never seen anything like it before!
 * Fisherman: Argh, can't people just leave this river alone already?
 * Fisherman: They just keep throwing trash into this river… Hasn't the decay already done enough work? Even the kappas don't bother fishing here.
 * Fisherman: Whatever man, you won. I hope this thingamajig can deal as a price. I got nothing better and it looks cool enough

Irrigation System
Head south along the river and fill the gadget with water at about [-1470, -4833]. When it is filled, go to the irrigation system west of the fisherman's house. Placing the gadget there will trigger an animation and a hole will open up south-west of the sprinkler. Head inside the hole to get the discovery.
