This is both a benefit for Kobo and a way to facilitate his actions and communication.
It's also a means of control and limitation.
To let him understand the cost of betrayal.
After all, the trust between them hasn't reached the level where Kane can fully trust him.
But it's not enough to guard against him either.
Hmm, then Kane took out the guild's seal device from the space equipment.
He smiled at Kobo and said, "This is the mark after joining the guild. Where would you like it to be stamped? It's the foundation of all guild functions and benefits, so you must have it."
Hearing Kane's words, Kobo nodded, thought for a while, and pointed to his shoulder, saying, "This area is relatively intact, so let's stamp it here."
Kane looked at it, indeed, other than the shoulder, which was a complete flat steel plate, other places mostly had hollow and protrusions of the mechanical race.
