The story takes place after the end of the show, and it is set that all four members of the machine team survive. As for how I survived, I wrote an article called "What Happened That Week." However, "Magic Number" takes place after the complete demise of the Samaritans. The original intention was to write about Xiao Gen's daily life, the follow-up of his relationship development, etc. However, he realized that daily life tends to turn into a running account, so he let the team encounter J. K. Rowling's magical world, hoping to use magic as a seasoning. Of course, magic can also bring dangers. For example, some remnants of the Samaritans are actually dark wizards...
Purpose: Use magic as a catalyst and test agent to allow their relationship to continue to grow.
