Monster Hunt (Part I)

"Monster Hunt! All ten teams will be given an hour to hunt monsters in this event!"

"The more monsters you defeat, the more points you earn!" 

"The monsters you could face will be the second to the fifth rank!"

"Defeating a monster in the second rank will give you one point!" 

"Defeating a monster in the third rank will give you ten points!" 

"Defeating a monster in the fourth rank will give you fifty points!" 

"And by beating the fifth-rank monsters, you will win!" 

From how the event will be, every team will be sent in simultaneously. The strongest monster should be at the fifth rank. 

Even the highest-rank competitor is at most fourth grade. So no one here should be able to defeat the fifth-rank monster. 

What happens if we encounter a different team? Could we eliminate them? The announcer didn't say that was against the rules. 

"Knowing the rules are out of the way, the Monster Hunt is about to begin!"
