After returning to the surface, Qi Suian immediately began hunting.
The combination of his reconnaissance network, satellite tracking, and uncanny intuition was unbelievably effective.
In just three short days, Qi Suian successfully captured a large number of special zombies.
This caused his Spirit Enhancement ability to jump directly from D-rank to A-rank.
The boost also increased from its original 10% to 25%.
'I still haven't reached the upper limit, but to reach S-rank, these special zombies are no longer of any use.'
Qi Suian understood that after A-rank, each subsequent level was a chasm, so it was normal for his progress to stall.
The enhancement of his Spirit ability was, in fact, quite similar to the Tai Sui God's armor value. For example, increasing the boost from 10% to 11% required only a single special zombie.
However, as the boost increased, the number of zombies required grew larger and larger.
