Is the flame collector given by VIP3, a mouse in the food war, permanent?
VIP4 can automatically collect (permanent) flames. VIP7 can automatically collect items (permanently). Double props and double experience can't be permanent (you can only buy them for 30 days at most, and the permanent double experience card seen in daily 1 yuan props is a BUG, but it actually takes 2 hours to buy them). If you want to be permanent, you can upgrade your VIP, and so on.
