All because the MCs system is one of those obnoxious ones that gives out the exact rewards that the person needs. Tsunade saving the allied shinobi, Zetsu and the unsealing, and here with Madara. Supposedly random reward yet gave him EXACTLY what he needed. Like those cultivation novels with the MC needing some rare item or plant that's not been seen for thousands of years. Then within the week he finds it. Really sours the enjoyment of the story when done so blatantly.
