Grading skill users

Maki and the others were about reach the Ramnag Kingdom kin seems to have a doubt.

kin: who are skill users graded?

maki: a normal skill user is twice as strong as a non-skill user and a 1-grade skill user is twice as strong as a normal skill user and it continues as the grade increases every grade skill user is twice as strong as his previous grade skill user and if you ask me raj is as strong 1.6 crore grade one skill Users as his grade is 25.

kali: yeah what is our plan as soon as we reach our kingdom?

maki: I will request the academy keep a selection test and whoever wins it will be sent to 2nd class.

kin: you think if you ask it they will approve.

maki: no but if I make a trade saying that I will give the academy 100 water crystals if they accept my request, they will.

kin: wait a minute wasn't it to build the kingdom's economy.
