In the Outer Domain Battlefield, eight days had already passed, and Guding had killed over 2800 members of the Double-headed Demon Race. According to his estimation, breaking 3000 wouldn't be difficult.
The points rule in the Outer Domain Battlefield was that for every 1000 kills, the points would double once. Breaking 3000 would accumulate tripling the points, resulting in at least 14,000 points.
Of course, this kill count only calculated single entries; it couldn't be accumulated on a second entry. Each entry into the Outer Domain Battlefield reset all previous data.
Moreover, Guding's scheduled entry time was ten days. If he exceeded the scheduled days, the points would still accumulate, but they wouldn't double. That is, if Guding surpassed 3000 kills on the eleventh day, the third doubling wouldn't count. Only accomplishments within ten days were eligible for doubling.
