Contestants embark on a relay
race composed of four stages demanding
precision under pressure: Cement Stacking,
Gravel Crushing, Sand Sifting, and Metal
Cutting. This episode tests their technical
abilities, starting with transporting cement
without spillage, then breaking down large
stones into gravel, followed by sifting sand
through a fine sieve without loss, and finally
cutting metal rebars to precise lengths. The
episode sets a high bar for skill, teamwork,
and perseverance.
