From his days as an E Rank Mechanist, Leon had been agonizing about a proper battery that could meet the energy needs of his increasingly complex mechanic constructs.
All the way from when he constructed his first Sword Drones.
As a D Rank Mechanist, this obsession reduced as by taking loans from the Geneforge Clans then, he was able to afford higher-caliber cell batteries.
Since then, he didn't upgrade a second time since the Freegrid Collective's cell batteries were more or less of the same quality as the ones being used by the Gene Army in the South.
But now, he finally upgraded again.
From his previous battery cell, Leon upgraded to the Mark-IV Flux Cell Battery, another Technician Class Specialization Exclusive Blueprint.
Each Mark-IV Flux Cell Battery is powerful enough to fuel a Major City!
It is not a coincidence that Ren Nora allocated Leon a budget of 100 million Neo Credits for his projects, his projects were just that high-level this time.
