Tu Qishisan is a warrior, a delicate name partly because she is the seventy-third child of her generation in her family, and also because she is the third to inherit the heroic name from her ancestors.
Don't get it wrong, it's not that her ancestors were heroes, but the first two to adopt the heroic name have already died, so she got the title of the third generation.
A cheap Rabbit-man, with an even cheaper life, not even bothering to come up with a meaningful name.
"I want a pleasant name... or maybe, the day I truly become a hero, I'll get one. With a legendary story of my own, no one will call me seventy-plus-three anymore."
"Seventy-three" was a bit troubled, yet as a hero, she was qualified, even outstanding.
The reason was simple, she was a true descendant of heroes, and indeed, the "Warrior's Sword" contained the power from her ancestors.
