the power increase will range from 400 to 800 per map im not sure tho. 27k max spending on it will be 2.7k mount myoboku pieces. on map 9 you will need 45 pieces to level up one cultivation.

I think below are the pieces you needed per map.Can someone correct me with this? I'm on map 9 so I can't provide pieces for next maps

45 per piece map 9 = 450 pieces needed

30 per piece map 8 = 300 pieces needed

25 per piece map 7 = 250 pieces needed

20 per piece map 6 = 200 pieces needed

15 per piece map 5 = 150 pieces needed

10 per piece map 4 = 100 pieces needed

5 per piece map 3 = 50 pieces needed

3 per piece map 2 = 30 pieces needed

1 per piece map 1 = 10 pieces needed

A total of 1540 myoboku pieces needed which is 15400 coupons. That will be roughly around 4k'ish power boost. If you don't have the deluxe suit yet yo ucan get it for 1.3k power boost. You are on a good place right now. :D

PS: Along the way you can get surprise packs containing myoboku pieces on each maps.
