The progress turned even faster after they strengthened the heart. Their bodies reached a new level of capability.
However, this method had risks. Even with mana, everything had to be done quickly.
With Qi, it needed to be done even faster.
Blood carried both Qi and mana.
As time passed, if they did not strengthen all their internal organs, the energy would damage their bodies instead.
Veins could rupture, internal bleeding could spread, and in the worst case, it could lead to death.
After the bone marrow, lungs, and heart infusions, the next organ they needed to strengthen was the kidney.
This step enhanced the entire cycle even more and pushed their strength to another level.
Since the kidney filtered mana and Qi and made them purer, Alex wondered if he could change his kidney to handle life force instead.
Vesa rejected the idea right away.
Vesa had his own ways to use life force to boost cultivation, but that did not mean Alex could extract it from Qi and mana.
