Locate the Secret Cave

Before venturing out, make sure you have a good pickaxe in your backpack. Move out of the cabin and collect the red berries and mushrooms during your journey. Go to the back of the cabin and keep moving in a straight direction while looting all the useful items. You will eventually find the nodes on your way. Equip your Stone Pickaxe and hold the ‘E’ key to start mining the nodes. Keep holding the button till the bar gauge fills up.

Breaking the nodes allows you to gain Rocks that are useful for crafting new items. So, breaking the nodes is the most effective way to acquire the rocks. You will find a cave near the river, but the entrance is blocked by the giant node.
Progress in the Cave

Hold your Stone Pickaxe and continue breaking the giant node to clear the entrance. Breaking this one allows you to get your hands on the 3x Iron Ore and 2x Rocks. Get inside the cave and continue moving in a straight direction.
You can find a node on your right, just after you get inside the cave. Use your Stone Pickaxe to break it and gain Iron Ore. You will use this material later in the game to craft new items. Keep finding the nodes and break them to collect multiple Iron Ore.
Obtain Nocturnal Crystal

Keep checking the durability of your pickaxe. Keep moving, and you will be attacked by an enemy. Make sure to hold the Stone Knife and attack the enemy. You need to hit the enemy multiple times to eliminate it. Block its attacks and hit the enemy with the right strategy.
Make sure your weapon has enough durability. Defeating this enemy allows you to gain Nocturnal Crystal by pressing the ‘E’ key.
Acquire Second Nocturnal Crystal

There’s another enemy in this cave, and defeating it allows you to gain another Nocturnal Crystal. Make your way back after defeating the first enemy and take the path on the right. Continue moving the path, and you will be attacked by another enemy here.
Use your weapon to block the attack by pressing the RMB, and attack by pressing the LMB. Once you defeat this enemy, you can collect the Nocturnal Crystal. There’s nothing more in this area, so you need to return to the cave.
