Done!
After grinding for a whole morning and half of the afternoon, Fang Heng finally met the conditions to level up to Level 36!
However, he didn't rush to level up.
Fang Heng contemplated for a moment and chose not to level up immediately.
They were about to break through the defensive barrier and enter the mausoleum area for exploration.
He decided to keep some zombie clones just in case.
After all, reaching Level 37 would definitely require more high-level mutant crystals, which wouldn't be easy to obtain in the short term.
Black Castle needed two hours to set up the shielding device, so Fang Heng had some free time.
He decided to return to the Zombie Apocalypse for a moment to check on Dodd's research progress.
...
In the Zombie Apocalypse, the research team was working tirelessly.
