I Want To Beat Up a Tiger
There's still a lot of holes for these types of novel, i just hope the subsequent ones don't just follow the same early plot, idea is good tho. If you want one example, then the way to be a paid assassin, it's too easy to be one, so easy that anyone can register to it, just that has many potential holes, example is, if you're rich and powerful, just make one account or your underling, have someone watch it, then see if you're targeted, now you can prepare for your life. I hope a new way to utilise this idea will be realised soon, it'll be fun to read.
