**Chronicle (questGroupNo)**: 2311
**Entry (questId)**: 3

## Objective

Eileen says the first thing you need for alchemy is a production node. Start by investing in the Coastal Cave node to connect an exploration node.

1. Talk to Egrin, the Coastal Cave Node Manager.
2. Select [Node Management]
3. Invest (requires 1 Contribution Point) in the Mining Node of Coastal Cave (Copper Ore, Powder of Flame).
4. Once the Mining Node is activated, your investment is complete.
※ You can retrieve the Contribution Points you have invested whenever you want.

_Connect the Coastal Cave - Mining Node (Copper Ore);_

## Summary

That's it. Well done! Many are confused at first,
but it's worth learning.
Once you know each node's strengths and assign the right workers,
you'll have a steady stream of alchemy ingredients.
