this game need booster to play! no booster no bns..

Hmmm... another question... do you all use booster to play this game?

Sigh... 灵石 quite expensive in 电讯9 >.>
Need to gather 24G+- to start crafting 水月 upgrade stone.
But at least there are still profit for that item, can't say the same for other lower mats though.

just click it... or is it just you ran out of fatigue (turned white) 0/3123132 exp

it limiting how much you can gain exp in a day.
you got a fix amount of exp you can gain per day and if you used it all then you cant gain anymore.
if you saved unused exp it will be brought to next day as x2 exp for a certain amount(depending on your vip lvl)

sounds like you picked blademaster? not much of damage output but well the survivability is fine.
You know there's a secret... psss psss psss...
use the official BnS booster omg...

what's so secret about it? psss psss not telling, just use it, continuously use it. 

go out drive like crazy then come back, sure will be fine 
up to you, make sure to take those that related to each other though.
most professions I already noticed some stuff that can make some profit, or useful in your playthrough either quest item or upgrading gear.

just noticed an item required for quest just now, costs over 17g... mats, from cooking and talisman making 
maybe I should make an alt later, if got time, to try out other classes and also for crafting
