This guy ... He is very stingy

"Dear customer, we can give you a twenty-five percent discount if your dear customer buys these two skills. The combined value of the two abilities is eight hundred creature crystals or thirty-three crystals from the mine, but with the discount, the value is six hundred creature crystals or twenty-five crystals from the mine. " The maid did the calculation and said the value.

(Twenty-five crystals from the mine? Twenty-five percent of thirty-three is a little less than twenty-five. It seems that she raised the price a bit to make the value accurate) Liu Yang estimated she would give twenty-four crystals and a little more, but it wasn't twenty-five.

(I remember that the value of the skills using the crystals of the creatures is much more expensive than using the crystals from the mine. It seems that they want the customer to use the crystals from the mine.) Liu Yang remembered the prices the maid spoke of.
