How many days does it take for QQ to ascend from one sun to two?

The formula is: D = the square of R + 4 multiplied by R (D is the number of days, R is the level)

According to this formula, it is not difficult to calculate that it takes 832 days from one sun to two suns ~
So, please wait ~ No, just wait two more years.

By the way, the sun is 320 days, the sun is 1152 days, and the sun is 2496 days ~
