it's a good cashback story, especially because it is not a random cashback. Instead, it's a fixed 10x cashback. (switches between pesos and dollars)
but the guy is too extra for me. At least some things make sense at the start, like investing gives a cashback and being able to receive a steady flow of cashback money by spending money for his restaurant. 
But then he gets into blackmarket and illegal stuff like funding and training a weapons dealer.
the skills and disciples concept is OK, but to me, unless you can secure their 100% loyalty, then its pointless.
he should just live a lavish life of a young master get all the girls, and be able to laze around.
I get their needs to be problems along the way, but still, I don't really understand why he is going into the black market other than being a bit wary of the future.
Maybe it's something I don't understand, so I apologise to the author if it offended you, but again, this is just my opinion.
