Forage plants to feed you worms (best i got is 39+ in lead). With quite some time your worms will get close to 39, but quite fast will go above 30. Feed them as much as you can and time to time put them in a bin (don't need to put more worms that needed to get 100% worm efficiency) to get some humus.
Look for water, lime, granite of the same element (here Lead). Make gardening pots.
Put a random tree in those pots with your best water and best humus.
Plant your tree in the ground, take sapplings (after 9 days i think) and replant them in your pots. Use this tree (let say it has 28 in lead element) to make a compost bin.
Now you have a 28 lead bin plus worms above 30.
Your second tree generation will be above thirty maybe and your humus is getting better.
Repeat all this, make a new compost bin when you obtain a tree with higher element that you already have.
Produce some pumpkin with your best humus. If this one is high enough, your pumpkin will have higher element that the plant you forage to feed your worm. And they will be able to go higher that 39 lead (in my exemple).
Feed worms, plant trees, make better compost bin, get better humus, get higher element pumpkin and keep going.
That's the way to reach 99% purity in one element. But the story doesn't say how long it takes.
But it's not possible with the current system to reach 99% doing it this way - you are constrained by the natural granite, lime and water you can find in the wild. There is no way currently to grind up the water, lime and granite purities. Best you can hope for is around 45-50 element value (not purity) pot MAX in the game right now - disregarding any alchemy adjustments which I am too scared to touch right now. So the 45-50 element value pot will drag down the resulting tree purity no matter how high you are able to get the humus or sapling up to.
