Siheyuan: I Traveled Through the Republic of China with the Red Alert System

Niu Dali traveled back in time to 48 years and awakened the red alert system. However, these red alert units are all pocket versions and have layers of authority restrictions. This unblocking of the first level of authority actually requires me to kill Japanese pirates? If this had come a few years earlier, it would have been easy to kill 8,000 Japanese pirates, let alone a few Japanese pirates. Now that they have long surrendered and retreated, do I have to go to those small islands to kill a few Japanese pirates in order to lift the blockade? The main reason is that our current small body cannot bear it. If we can unlock higher permissions, then we will definitely make them all our acquaintances. For now, we should just be patient. How to complete this task? Wait, what do I see? The opportunity to unlock permissions has come, what are my soldiers waiting for? Give it to me... (The protagonist has traveled through time and has a system, so it's okay for him to be a little bit awesome. So if the reader feels that the protagonist is too awesome and a little bit too hooked, then the reader is asked to just read this book as a mindless read. The author's writing is limited, so please bear with me here, thank you!)
