You should let the world unfold. A 10-year time jump and then explain the development of the village from different points of view. Anyway, good chapter. This would already be a personal request but, what if you do the mc create a dome around your country when the second shinobi war begins. Then open it shortly after starting the canon. You know to see how the characters react to a country much more advanced and powerful than theirs. By the way you create an excuse, like lost treasures, to send the deadly sins to explore the continent.
If you do a timeskip we will not know the casus belli of the war better create a chapter whether in different POV so we may be informed the reason of the war except the lacking of resources. For instance in ww1 we all know there are already alliances, rivalries among the super power at that time such as the arms race of germany and france, however, the assassination of the heir of austria hungary was the spark to start the war and there are many factors but that is the spark it needs to trigger the war.
