Over the next few days, Tamura Hiroshi mainly sparred with the Third Raikage, adapting more quickly to the boost Swift Release gave his speed.
The fusion of the Swift Release Kekkei Genkai had indeed greatly enhanced his chakra reserves.
After reaching Kage Level, he had originally been able to produce nearly one card of chakra normally. After the Swift Release chakra had transformed his body, the amount he could produce had skyrocketed tenfold, reaching ten cards.
That still couldn't compare to the Third Raikage's Tailed Beast-level chakra reserves of over a hundred cards, but it was already considered a normal Kage-level amount.
Ordinary Kage-level Experts could reach ten cards of chakra or more. Even Kakashi, in the original story, had only had low reserves early on. After Sasuke left, he had clearly pulled himself together, and his reserves had increased as well.
More importantly, though, that Sharingan had held him back. His chakra was constantly being drained, so naturally he couldn't unleash much. Just look at how powerful he was during the Fourth Shinobi World War.
If the Sharingan hadn't weighed him down, and he hadn't been crushed by one blow after another until his spirit was broken, Kakashi's chakra reserves wouldn't have been poor.
The one-card standard Tamura Hiroshi had set was based on an ordinary jonin's chakra reserves. It actually had little to do with Kakashi; he had simply borrowed the word "card" as a unit of measurement.
Now he had finally reached the Kage-level standard. That was why he could spar at high intensity with the Third Raikage every day.
Of course, the Yang Seal was still essential to keep rapidly extracting chakra from damaging the foundation of his body.
He didn't want to damage his body by extracting chakra too quickly too many times and end
