Golden Disc
I love how whoever wrote this can't remember the cost to level up buildings or how much resources the character has, like 5 chapters ago he had 1208 energy stones and 15 of the special crystals. How is it so hard to remember what was written like 5 chapters ago. Honestly it makes the story so much worse, is it just a bad translation or is the original Chinese author a moron?
also it was 50 of the crystals he needed up until this chapter where now it was only 5... but the next level is 500... and why would it be this kind of gap 1, 5, 50, 500 you can't just add a zero there should be a logical progression... also is tier 9 the highest creature out there? its a good story but really need to work on the readability of it
