Doomsday Heroes (Territory 2): "Who is here? Anyone knows what is happening?"

Galaxy Guardians (Territory 1): Hello! Doomsday Heroes! I am glad you guys are also alive! As for what is happening, I don't know. Our guild was suddenly upgraded.

Hardcore Survivors (Territory 4): Our guild was upgraded too!

Survivor Camp1 (Territory 3): Oh my god! I am so relieved to see so many guilds active! Did you guys fight the weird insect yet? I thought the whole world was going to get wiped out. I am also not sure what is happening, but our guild is upgraded too!

Team Earth (Territory 5): Wait, I think all our guilds are upgraded. Look at the ranking list of the guild. There is a separate ranking list for each territory, and there is also a global ranking list.

Warriors of Change (Territory 1): Oh! You are correct! All the guilds have been somehow upgraded overnight! But why suddenly now? Didn't we have to pay mana cores? What happened now?
