In Naruto Shippuden episode 467, how was a normal villager able to use jutsu? There was a scene in Episode 467 of Naruto Shippuden, where Ashura taught ninjutsu to a villager. 

But I have been led to understand that only descendants of Kaguya can use jutsu (because originally Kaguya was the origin of chakra). 

How can they use jutsu if they're not descendants of Kaguya?
Yes you are right but :


  Hagoromo travelled across the land, giving chakra to everyone in the
  world as well as spreading his ideals and religion


so it is possible that Ashura might have just shared his chakra just as his father Hagoromo did.
