Let's bet

"Alright, since everyone is here," the speaker said with a pause, "let's announce the rules for the final stage." With that, a bunch of data appeared on the screen.

Here are the rules:

- The simulation area will shrink at regular intervals.

- The time ratio between the real world and the simulation world is 1:6.

- Killing other players, whether directly or indirectly, earns 100 points.

- Killing monsters of F/E/D/C/B rank earns 10/20/40/80/160 points, respectively.

- Occupying F/E/D/C/B-rank monster nests for five minutes earns 20/40/80/160/320 points, respectively. Once a nest has been occupied, it can't be used again.

- No rules apply within the simulation capsule.

.....

"Isn't this the same as the old rules?" someone asked.

"Yeah, except for the addition of the B-rank monster."
