Naruto and Minato attempt to bust the walls down. They fail. Naruto has idea and tells everyone to all use as many smoke bombs as they got. Obito claims that nothing can stop him and fires off the attack. Endless explosions go off inside the force field. Obito desummons tree and sees no signs of anyone except a badly injured and very pissed off madara. Madara scolds Obito for wasting his time with a useless jutsu as naruto and the others appear via tunnel made into the ground at the last second. Obito attempts to summon tree again only for it to fail as he begins to realize that his chakra is slowly depleting.
