This is the second puzzle I am making in a series of arrow sudoku puzzles that require set theory to solve.
This one should be a little easier than the first one, but still really hard.
If you are not familiar with set theory, watch Simon explain it.
Standard sudoku rules apply.
Numbers along an arrow sum to the number in the connected circle.
Digits on thermometers are strictly increasing from the bulb to the tip.

Total insanity. One of the hardest 'true' breakthroughs I've seen despite the initial idea being similar to the previous puzzle, and I don't even think that I got through this one in the nicest way possible.

Very difficult, but compared to the previous question, it’s still easy to find the entrance (just a little bit), and it’s really poisonous.
