What makes the green channel different from other channels?

I heard some player is asking why the monster is stronger during the drop rate is drought, 

here i would like to say that there are a different between the green server and red server.

The green channel means that it is the "hot server". Monsters whose levels are ranging from 1-100 have 25% less HP compared to other channels. There are events that are only held in the "hot server".
