I'm confused.
Didn't he want to use the mirage fox material to imbue his armor with automatic repairs? Why are they now talking about doing the tippet? I guess he's trying to present it as a gift to the lord for some advantage but it really seems to me like it'll just invite attention and trouble. The lord doesn't even acknowledge having lost the tippet, so it's not like they can publicly reward Yajin for delivering a mirage fox.
I can't say I understand wanting to pass off the job to another workshop either; they may have known how to make the tippet in the past, but there's no guarantee that they've preserved the technique, especially since they appear to employ lots of people and mass produce goods which aren't top quality.
Then there's the negotiation with another noble, who his research has deemed to be a dangerous person, but he's taken in stride. I guess he's having fun, and couldn't really refuse the invitation to drink, but being dead drunk is definitely not great for negotiations and we still don't know what this guy wants though he was apparently willing to wait a few days and Yajin wasn't attacked in that time period. I guess that, for now, only the guard, their noble captain, and the workshop know about the mirage fox so things are relatively calm.
Well, at least he apparently broke the level barrier and got new skills so he'll be able to level a bit later, but that doesn't really help him right now.
