"Shadow Clone Technique!"
Using Liumu's hand, Minato released shadow clones at the same time as him.
Countless puffs of white smoke erupted, and nearly a hundred clones prepared to join the effort to open the mechanical wall.
Unexpectedly, Liumu, who was holding the Rasengan aloft, suddenly shouted to everyone from a distance, "Stand back!"
As he spoke, one of Liumu's clones suddenly flashed forward, crouched, and slammed a fist into the wall.
Boom!
With a thunderous crash, huge chunks of stone scattered and Liumu's clone vanished. An enormous hole had already appeared in the wall before them.
"Who cares about the mechanism? It's just opening a door. Why waste so much time?" Liumu muttered helplessly.
Beyond the mechanical door lay the dilapidated ruins where Liumu had first met Sara. From here, everyone could climb along the pipes to safety outside.
However, perhaps the shadow clones had affected the chakra Minato and Liumu were using to maintain the Rasengan in their hands.
Under Liumu's astonished gaze, his Rasengan and Minato's actually seemed to be quietly merging. The blue and green gradually converged, fusing completely within just a few breaths.
"This..."
Minato explained, "Two similar masses of chakra can merge with each other, and the same goes for Rasengan. Their matching rotation rates and sizes made them merge spontaneously."
Feeling the fierce force emanating from the merged Rasengan, Minato looked shocked as he declared proudly, "This new form of Rasengan-I shall call it the Super Ball Rasengan!"
"Liumu, go!"
Choza shouted from beside them.
Liumu nodded at the shout. Minato attacked first, using the Shuriken Shadow Clone Technique to stop Anrokuzan's centipede-shaped puppet from repairing itself.
"Liumu, go! Anrokuzan's real body is in the puppet's chest!"
"Right!"
Liumu roared and leaped high with the Rasengan held aloft, striking straight at the chest
