Even though the fight didn't last long, Dilan was quite satisfied with the outcome.
He was only scratched once while fighting against the ten strongest zombies at once.
Absorbing all Essence crystals without minding whether they were ordinary, Bronze, Silver, or Tier-1 Essences, Dilan nodded his head with a sly smile on his lips.
"Maybe I should focus on clearing one of the hospital's towers on my own…boosting [Immunity] might be quite important for the future!"
Speaking to himself while glancing at the requirements to upgrade his passive ability, Dilan knew that they had to absorb far more ordinary Essence and Bronze Essences.
As such, he was already coming up with a plan to upgrade it.
But before Dilan would avert his focus on his abilities, there was something else he had to take care of.
By the time most of the Essences were absorbed by him, Williams and the others had also reached the first floor.
