This puzzle is the first destruction puzzle I set since 2022, making it three years since the last time I made a puzzle with this constraint. This puzzle serves as an easier version of Parasitic Destruction, so please check out that puzzle if you enjoyed this one.

The rules are as follows:

1. Place the digits 1-6 once in every row and column.
2. Chaos Destruction: All given regions must be "destroyed" by making sure they do not contain all the digits 1-6. The grid also consists of six hidden, orthogonally connected regions that each do contain all the digits 1-6. Digits in circles represent how many of its orthogonally and diagonally adjacent cells, including itself, belong to both the given and hidden regions where the circle resides (i.e., where they overlap). All circles are chaos destruction clues.
3. Parasites: Draw parasites moving orthogonally through the grid that connect all circles that share the same digit. Parasites may not move diagonally, branch, or cross themselves nor each other, but they may touch themselves and each other otherwise. The start and end of each parasite must occur on distinct circles, and all circles belong to parasites. This puzzle contains one larva and one adult.
   • Larvae must contain a total number of bends equal to the digit in its circles, and at least one of those bends must occur on a cell where its circle-digit appears outside of a circle.
   • Adults must contain a total number of bends between each circle (not counting bends on circles) equal to the digit in its circles. Additionally, all the digits an adult crosses are grouped by the hidden regions they belong to, and the sum of all the digits in each group must be divisible by that adult's circle-digit.

Here is an example to illustrate the rules (note the example puzzle is not solvable, it only serves as a showcase).



The puzzle is available on SudokuPad and Penpa (answer check is on sudoku digits and parasites using the green line tool). Have fun destroying!
