How do you get to lvl 100 fast?

There are 2 ways:

_First: Go to the city in a area near military base where spawn Pets and just farm them for days ull get tons of Items to craft an sell them for VIP then buy tags with the VIP u earned.

_Second way: do many quests as u can for weeks or days and lvl up.

1. Buy item from the boy and sell it fro tags

2. quest one hour to see how much u earn per hour and after that quest around 3 or 4 or even more to have the right amount to level up

Quest are good for a handful of tags depending on your level.

Selling weapons in the marketplace for tags or vips is a good way to get some but it's not guaranteed to be a primary source.

(Depends on what the weapon is)
