Hacked by me heheheheh!!

100,075m was the previous longest recorded distance on CastleMiner Z. It was accomplished by two friends in
Castleminer z 5

The Bedrock wall's lantern top.

Freebuild and posted onto YouTube (however has been taken down).

the longest distance recorded still on YouTube is 100,000m accomplished by Sickdistic gaming.

Currently the longest distance recorded is now 10,676,056m on CastleMiner Z, obtained by M3RKFREEZA, took 2 days to reach. Reaching this distance corrupts your save data, making your world innaccessable.

It is NOT recommended to travel here in Easy, Normal and Hardcore Modes as Zombies and Skeletons will approach within a Split-Second.
