@inhuman First of all I wasn't talking this specific manhua, I was talking about manhwa/manhua with same plot.
Secondly, what kind of probability or resources management are you talking about. In earlier comment you stated that strategy and management can overturn the battle and I agree with that but with insufficient manpower and necessary tools (as it is early days of spiritual awakening thus one cannot develop spiritual tools in short period of time or even if they develop it they can't mass produce it) one can not win the war. In my opinion, as I specifically mentioned US so I thought you were defending US.
