Selling hydrogen balloons was an illegal activity that could go unpunished if sales were small and no real danger resulted.
The main reason was that hydrogen balloons could easily explode.
But as far as Joey knew, there was not much hydrogen in the atmosphere. Creating so many clones filled with hydrogen would be difficult.
Then there was only one possibility!
His opponent had merely conjured mobile monster skins. His actual specialty was Transmutation: he transformed his own Nen into hydrogen and injected it into the monsters as he conjured them, producing huge explosions to defeat his opponents.
The fact that he could create such Nen Beast Clones and fill them with hydrogen also showed that his aura capacity was certainly not to be underestimated.
But classifying his ability as atmospheric manipulation would be wrong.
Because there was only one thing he could control: his own Nen, transformed into hydrogen!
It was practically impossible for Joey to seize his opponent's hydrogen through Weather Report, because that hydrogen contained his opponent's Nen and would obey his commands completely.
So Joey needed to approach this from another angle.
Without being able to control the hydrogen, how could he prevent hydrogen explosions?
Targeting the flames should be the simplest method. As long as no flames appeared, even if these clones were punctured, the leaking hydrogen would pose no threat to Joey and the others.
With Weather Report, Joey could obtain enough oxygen to supply everyone.
But if oxygen was present, flames could easily appear. His opponent did not even need to create a flame. Once enough Nen Beast Clones burst and released their hydrogen, the slightest spark would cause an explosion!
So what Joey needed was a life-support oxygen system.
He had seen plenty of such things in hospitals, and besides, he could even
