I'm actually surprised they gave it as the highest reward for 500 refinement rebate.

It actually cost 5000 coupons in the lucky wheel event as the highest spending reward.

This is end game material guys. You won't see the effects until you are refinement level 10 with orange purifys.

Because after you get there, there is literally no way to improve yourself other than this pill, that is why it is called breakthrough pill.

Majority of us here aren't even at the level needed for a breakthrough lol.
