Oh i found a way to beat it i was using cersion fist and a 2 star Lee for the greta dm for the taijutsus all eight inner gates is chakra free btw. A 2 star naruto beacuse the clones will defend off their attack for a while.

You should use stone fist jutsu and earth style enhanment also use konhana hurricane too. I also used Kakashi hatake and he was good for stopping attacks because twin lighting blade shiver to do it.

PS: Stone fist jutsu can stop their attack so use it wisely. Also Kakashi's pursuit fang jutsu use it on water. When the guy use water dragon epxlosive or about to use stone fist or kakashi's lighting blade shiver to stop it

Its basically impossible
