I want lot of blue crystals
We can't really grind much in LR because we are limited by the amount of energy we can use per day. It is not like we can play for many hours for a week and we can get a lot more blue crystal after that.
Thus, the maximum amount of blue crystal we can get from LR every day is not enough compared to what is needed.
Please stop asking us to grind because even if we want, we cannot make it happen.
After playing every day for the past 5 months, I managed to reach level 18.
At level 18, I have 8 lv 18 blue crystal mines and 6 lv 10 battle altar
The maximum I can get in a day is 789,120 blue crystal assuming I am able to collect all of it as there is a limit in storage mine storage.
Well, one level of adeptness requires more than 2,000,000.
24 hours * 2580 * 8 = 495360 (8 lv 18 blue crystal mine)
24 hours * 2040 * 6 = 293760 (6 lv 10 battle altar)
495360 + 293760 = 789120 (total amount of blue crystal per day)
Adeptness level 100 requires 191,657,000 blue crystal
Inscription level 100 requires 14,672,380 blue crystal
Total blue crystal required for lvl 100 inscription and lvl 100 adeptness = 191,657,000 + 14,672,380
Total number of days required to get this much of blue crystal from a lvl 18 LR is 261 days
(191,657,000 + 14,672,380) / 789120 = 261 days
one hero alone requires at least 261 days.
6 * 261 = 1566 days = 4.29 years even for just a team of 6 heroes.
Since my LR will level up, it will probably take me less than 4.29 years, so maybe 3.5 - 4 years?
I beg you to stop asking us to grind 4 years for just 6 heroes.
Unfortunately no one will give it to You. You must either get it by your own or buy it. There is no other way. You can make Suggestion thread with request for increasing Blue Crystals around received from LR mines, but nothing else. And no one know if devs will listen to it.
As Cichociemiak stated you only have  choices, either grind it out or out right purchase what you want. I understand the desire to be among those in the forefront for leveling your heroes, but unless you are willing to pay the price, you will have to be patient. Besides there are other means to obtain blue crystals, a number of free events and chests contain them. Now if we were of a mindset as one of our members, we could say, you mean you didn't save any, oh well I have more then enough too bad and so sad for you, we don't need them so you shouldn't either.
