The Fifth Level
The Forcefield upgrade was incredibly swift, the veil expanding and condensing until it was stronger than before. After two consecutive upgrades, the Forcefield was just as strong as a Perfect Barrier, enough to hold back even a Nascent Soul Realm Beast for a short period of time.
With this, William was much more confident in surviving these ruins. The Forcefield didn't cost any Mana, and the range would now extend to up to ten meters, which would hopefully prevent him from being sneak attacked.
William decided to save the rest of his Potential Points. He spent the remainder of the time working on setting traps and reinforcing the ceiling.

Oh no!
