i dont know if someone has made a thread on this but it appears from the trailer that boruto throws his rasengan which means he may be close to already surpassing naruto since i recall it being said that it takes a lot of effort to propel chakra when naruto was using his rasenshuriken and boruto...
which would u use to save yourself
1.about to be shot bullet heading straight for you
2.falling from a ten storey building
3.about to be hit by a car
4.drowning
5.Getting electrocuted
And you cant rely on durability or speed unless its part of the jutsu
