One of the many quests in Hollow Knight Silksong requires you to find a strange substance called Plasmium, which can be hard to locate.
The Alchemist's Assistant quest is triggered when you meet the Alchemist in Wormways, which is an area that could take a few hours for you to reach. When you meet Zylotol for the first time, he will ask you to find three Plasmium samples, spread all around Wormways.
This guide will help you find them quite easily, and it's advisable to follow the same order mentioned here.

How to find all Plasmium in Hollow Knight Silksong
There are a couple of prerequisites for finding the samples. You'll need to have unlocked Wormways first, which is obvious. Before collecting the samples, equip the Needle Phial in your trap slot. Without doing so, you won't be able to collect the Plasmium samples.
Two of the three samples are pretty far off, while one is near the Alchemist's room. The samples are hard to miss in the dark thanks to their bright blue glow.
First Plasmium location
Once you leave the Alchemist room, go downwards and to the left to go past the falling worms. Keep going until you reach a small hill. Use your cloak's float ability to move towards the blue light on your right (look for an alcove near the light).
After reaching the location, activate and charge the phial until it's full to collect the Plasmium.
Second Plasmium location
We can now move towards getting the remaining two Plasmium samples located at the bottom of the Wormways. Travel two rooms down from where the Alchemist is located. You'll reach an area where your surroundings are dark, and there's an entrance. Use the entrance, and keep travelling right.
You'll come across a set of corridors; go down through them, and reach an area with moss. Keep travelling to the right, and you'll get the second sample location.
Third Plasmium location
To get the third sample, you'll need to go left and downwards from the second sample. Keep travelling left, and you encounter a small enemy and a few spikes. From there, go up and then left to the next room. You'll have to use your dash to skip the falling worms. Keep going left, and you'll eventually hit a wall.
Use your Wall Climb ability to slide down to a platform (there are spikes to avoid). Break the wall on your left, follow the path using the platforms, and once again slide down to reach the final location.
Once you have found all three samples and returned them to the assistant, you'll be rewarded with a new charm named Plasmium Vial. This item offers a temporary mask of health when you activate it, despite being a trap.
