he should have used rasengan in closed range
Fortunately for Kitsuchi, Fujin disappeared from his spot, leaving behind an afterimage. As soon as he disappeared, multiple stone pellets pierced through the afterimage. Fujin appeared on top of Kurogane and shot the Vacuum Bullets at the jutsus launched at Kurogane. The Vacuum Bullets pierced through stone pellets, spears and other jutsus that they hadn't managed to defend against, successfully stopping them.
