The more blood pumped through his two hearts, into his veins, the more he felt as though he was becoming stronger.
He could feel his veins, muscles and bones become increasingly stronger to match strength with his second heart.
Just like when a car suddenly gets two different engines powering it, its efficiency would be greatly boosted.
The feeling weird. Previously, the limit of a genetic soldier's speed and strength was largely due to the genetic structure which has been termed as genetic chains or constraints.
To evolve to the Super soldier stage one needs to break the gene chain by restructuring and remodifying their cells to form super cells and then adding foreign cells into that cell to modify the gene structure.
With the modification, the gene constraint is removed and the genetic structure is altered, granting untapped power and unimaginable strength to use Dust!
