Hello, welcome to "Zero"
Depending on the energy contained in your body, you will be classified as "Rain" or "Ling"
In "Rain", you need to deal with the less threatening "Knot"
In "Ling", you need to deal with the more threatening "Knot"
Remember, members of "Yu" and "Ling" cannot perform the same task at the same time except under special circumstances.
Because "Yu" is the head of a snake and "Ling" is the tail of a snake.
And if the first and last words are linked
Guess what will happen...
Concept: Two bodies, four souls
