Down the Earth-Stained Path ( (つち) まみれの (みち) Tsuchi Mamire no Michi o) is the one hundred and sixty-second chapter of the Dr. Stone manga.


Hyoga uses his kan-ryu style to dig a tunnel. While he is currently successful, Tsukasa notes that eventually they would need a drill to dig through bedrock. Kaseki produces a drill bit (which he dubs a "spiral sword"). Ryusui decides to have Taiju deliver it to Chrome via the mobile lab due to the latter's immense strength. Taiju requests that Luna and Yuzuriha look after the unconscious Senku.

As Taiju drives, he is spotted by Carlos and Max. They get into a scuffle about who will chase the car and who will watch Luna, but Taiju unexpectedly greets them both. Much to their surprise, Taiju asks them to join him, given that their orders were to monitor him anyways. Carlos alone accompanies Taiju and asks him about Luna. Taiju answers that she was looking after Senku and she would not be treated poorly. Though Carlos cannot understand Japanese, he feels that Taiju is trustworthy. Due to Taiju's poor driving skills, Carlos takes over.

Once Taiju arrives at Chrome's location, Chrome ties up Carlos, much to Taiju's horror. Chrome justifies his action saying that Carlos was still an enemy and would leak the tunnel operation to Xeno. Carlos is shocked at hearing the word 'tunnel', but doubts that they would be able to make one due to their age. The tunnelers eventually reach bedrock, at which point Taiju uses the drill to dig through it, much to Carlos's shock.
