You unlock the Void thing in Sell Lemons at around 500 quadrillion investors. Several recent guides also say the portal may show up a little before that visually, but it becomes usable once you hit the investor requirement.

What that means

  • The portal is tied to investors , not just cash.
  • Some guides describe the number as 500 quadrillion , while others say 501.2 quadrillion total investors when counting all investor sources together.
  • The safest rule is: keep rebirthing until you’re around the 500 quadrillion investor mark, then check the portal behind the Alien.

Quick tip

If the portal is visible but still locked, that usually means you’re close but not quite there yet. Hitting the investor total should unlock the Void Evolution menu permanently.

TL;DR

The Void thing unlocks at about 500 quadrillion investors in Sell Lemons, with some sources saying 501.2 quadrillion total investors.
