I designed these two puzzles to work together, with the values obtained from the first puzzle being the clues for the second. The first puzzle does not need input from the second puzzle to be solved.

Rules for Part 1:

• Normal 9x9 Sudoku rules apply.
• The cell with a grey circle must contain an odd digit
• Each red pill shape value is a two-digit number read from left to right or top to bottom
• Following the purple path from the top left to the bottom right, each red value is equal to the sum of the previous red value and the digits on the path leading to the red value
• Paths between red values are also Renban lines (cells within red pills do not count towards Renban lines). Digits on a Renban line form a set of non-repeating, consecutive digits in any order
• A "?" represents any number, including multi-digit numbers

Example:

The first puzzle:

Once you have solved this puzzle, take the numbers in the 9 red values in order along the path and use these values as the sums of the cages for the 2nd puzzle.

Rules for Part 2:

• Normal 9x9 Sudoku rules apply. Place the digits 1 to 9 exactly once in every row, column, and box
• Digits separated by a black dot have a 1:2 ratio, meaning one is exactly double the other
• X-Sums: Numbers in cages outside the grid indicate the sum of the first N digits, where N is the digit in the closest cell to the clue. These sums need to be determined by the solver
• Digits are from the 1-9 range only, no zero can appear anywhere in the puzzle (i.e. 10 is not a valid sum for an X-Sums)
• Digits in cages cannot repeat, including in multi-digit numbers. (i.e. if a cell in a cage contains the number 12, 1 and 2 cannot appear in any other cell of this cage, including 1X or 2X)
• Numbers in cages sum to the corresponding red values from the previous puzzle (numbered along the path, from top left to bottom right)
