Hi, Playtime player, don't be anonymous.

I believe those screenshots are invalid because miracle medicine is an in-game item included in the guild package meant to attract more WoE guilds to join the server. Also, all the chars highlighted in the screenshot were deleted a loooong time ago in response to people getting mad and new chars have been created and leeched without miracle medicines. If you've noticed, ICHIBAN has skipped many WoEs because they are not yet prepared.
"Parachute, got caught command leveling characters and the guild" -- miracle medicine is an item in-game as part of a guild package to level chars, no intervention necessary from any GM. The experience gained on the screenshot seems like a bug to me as the numbers fluctuate from all the characters on the list. Will wait for official response from Parachute as my knowledge on the server itself is very limited ~
If the MM does give 4M exp as u say, and the exp u gained from it would be doubled (as seen on SS#2), that would be 8m per MM. 8M * 200pcs of MM = 1.6B and split this between 6 chars would give u 266M exp each, not including any exp gained if battle manuals were used.
