Spirit Vein · Prestige — the two generators

Two spirit-stone sinks that run the whole game: one raises how fast you earn, the other takes the overflow once everything else is maxed.

At the Sect Hall, raised with SPIRIT STONES (not contribution). Up to 40 levels.
Per level: offline cultivation +1%, Sect Hall income +2%, and the cultivation store holds 10 minutes longer.
Level n costs 300 × 1.18ⁿ stones — level 1 300, level 20 8.218, level 40 225.114.
Capped by your sect: 3 × sect level. You cannot grind straight to the ceiling.
The offline cultivation store: 3 hours base plus more per Spirit Vein level. This is why a night's sleep no longer pays the same as a fifteen-minute break.

The late-game sink: 50 levels, each adding +1% sect income.
Level n costs 5.000 × 1.15ⁿ stones. No sect cap — whenever you have spare stones, there is somewhere to put them.
Sect chores: 3 of them, repeating every 2 h, each paying 4 + your sect level in contribution.

This is enough to start playing. Read the rest as you go.
