How much alcohol a normal person can drink in one go depends on the size of their mouth and their swallowing speed.
How strong the alcohol they can handle depends on their body's capacity.
In general, the 'alcohol' a Wizard can 'drink' is just that strand of Power of Law.
Including Sunan.
So he can only use the magic cube to synthesize a stronger Power of Law to increase the 'alcohol strength'.
What he is doing now is finding the 'upper limit of alcohol strength', which is the maximum intensity of the Power of Law he can endure.
After spending four or five years, Sunan finally tested the most suitable synthesis limit.
The final experiment showed that increasing the Gravity Law comprehension progress by 0.01% required at least four and a half months of training.
"At this rate, after absorbing the fruit of law, I should grasp the Gravity Law in about two thousand years."
