Yes. If you already processed the Fist of Darkness in the Secret Laboratory and saw the confirmation message, you can leave and rejoin later to continue the Cyborg puzzle without getting another Fist. But if you already have an unprocessed Core Brain, process it at the lab before leaving: the item cannot be stored and may be lost if you log out or die.
What happens depends on your quest progress
| Your state | What happens if you leave | What to do next |
|---|---|---|
| You processed the Fist of Darkness, but have not obtained a Core Brain | The puzzle progress is reported to save. You can rejoin later and continue without another Fist of Darkness. | Return to the Secret Laboratory and continue the Core Brain step. |
| You obtained a Core Brain, but have not processed it | The Core Brain is a held item that cannot be stored; leaving or dying before processing it may cost you the item. | Take it to the Secret Laboratory and process it before logging out. |
These are separate milestones: the Fist-processing step records puzzle progress, while the Core Brain is a separate item you must bring to the lab. The confirmation reproduced in Roblox Den’s guide reads: “Your <Fist of Darkness> has been processed. Please supply a <Core Brain> to continue.” Roblox Den’s Cyborg guide says the progress saves after that step.
How to continue after rejoining
- At Hot and Cold, go to the Secret Laboratory and process the Fist of Darkness.
- Wait for the message confirming the Fist was processed and requesting a Core Brain.
- If you leave at this point, rejoin when ready and continue the Core Brain step; the guide reports that you do not need to process another Fist.
- Continue the Order raids until you obtain a Core Brain, then return to the lab and process it to open the next part of the Cyborg puzzle.
The Blox Fruits community wiki also reports that players can rejoin after inserting the Fist and later obtain a Core Brain. Both accounts are secondary guides rather than an official developer statement, so treat this as guide-reported behavior; game mechanics may change with updates.
