While ordinary heavenly materials and earthly treasures didn't have much effect on him now, accumulation over time could still increase his stamina limit considerably, as long as he consumed a significant amount.
However, triggering such an adventure would have to wait until Zhang Yanhang returned to the Main World, which was still four days away.
During these four days, he had three tasks to complete: the first was to clear the small Crimson Iron Ant Nest Dalagu, the second was to excavate a passage to other Crimson Iron Ant Nests, and the third was to take advantage of the remaining time after the excavation to see if it was possible to clear out the new Crimson Iron Ant Nest.
For now, since Zhang Yanhang had already located the remaining Crimson Iron Ants within the small Crimson Iron Ant Nest Dalagu, he felt confident that he could eliminate these ants within an hour and thus clear the entire nest.
