Hear me out. What if all of the nations, major and minor came together to form a sealing jutsu that covered the entire earth? Why? Well the otsutsuki and Code wants to create a chakra fruit that will suck the life out of earth, killing most if not all of humanity. In the timetravel arc it was revealed that Otsutsuki, specifically Urashiki has a hard time absorbing chakra through a seal. As much as alot of people feels the filler isn’t legitimate, there’s sprinkle of foreshadowing all over the anime as well as concepts that are used in the manga. Anyways, eventually humanity might have to come up with a large sealing like jutsu for earth anyways when it comes to things like asteroids or even just evading more otsutsuki form detecting earth. A seal should make it much harder to use a divine tree to create chakra fruit and will create a whole extra layer of protection as a whole. This could be like a Great Shinobi Alliance Jutsu Part 2 or something.
Also if you’re curious about how they could even create a seal so strong. They could use Boruto, Kawaki or both as a base to cast the jutsu possibly creating some sort of shinjutsu level sealing jutsu that can’t be undone until Boruto weaves a sign or dies. What do you think?
And if there were to be like an Otsutsuki invasion, this concept can prove to be very helpful as an extra layer of protection.
