You have to understand—this was supernatural power!
It wasn't some ordinary thing, and what's more, this kind of supernatural power was different from all the others. Most other supernatural powers required talent, and many didn't have any hereditary traits.
But chakra was a supernatural power that was one hundred percent hereditary.
One injection, a lifetime of benefits. Wealth for a hundred generations. You could even say this was the evolution of civilization. Once everyone in an entire civilization had been injected with the Sacred Blessing Serum, humanity as a whole could be said to have taken its first steps toward a spiritual ascension.
And the price was just ninety-nine dollars!
A price anyone could afford if they set their mind to it, no matter how poor they were. It offered a chance to change their fate.
After all, even a homeless person could find a way to save a dollar a day. In just ninety-nine days, they could buy the Sacred Blessing Serum that would change their fate.
