The Lunar New Year Tournament did not actually have a fixed duration, and "one month" was just an estimation of the event from the opening celebrations to the closing ceremony. The actual duration of the tournament depended on the number of young female Posthumans they could kidnap from the outside world. In a good year, the organizers could get about a few hundred contestants; there were years where it continued with just about 40 or 50 contestants.
This year, there were only 100 contestants. With two rounds every day, about nine to ten female Posthumans would be expended each day, so the event would only last for about slightly over ten days. With the celebratory atmosphere around, the tournament merchandises were already selling like hotcakes in the city.
[1]- The author used a different term to refer to Posthumans in this chapter to show that the residents in the Garden of Eden look down on them, I only translated the term as ‘mutate’ when people are speaking because I find it too confusing.
