By controlling the vast chakra flowing from the Ryūmyaku (龍脈, literally meaning: Dragon Vein), the user is able to convert the chakra and use it in various ways including to power an entire city and control a vast amount of puppets. If not stopped the user would have a unlimited source of energy to feed off of.
Trivia
- Mukade was able to use the chakra to accelerate his healing and transform his body in a similar way of a jinchūriki and their Tailed Beast.
