Oh that makes sense more then how I looked at it e.eWell, the way I always envisioned it was that we isolate some calcium in our bones, primarily the fingertips. As we isolate the calcium and chakra, we allow it to create a buildup. As we create the buildup, we cause an amount of pressure to form behind it and release that pressure and a portion of the calcium, allowing the bones to be forcibly expelled as the remaining chakra and calcium allows the bones to regrow into more bones that you recreate the same effect with, allowing us to create a long chain of drilling fingertips.
As told, Wendy begins channeling her chakra into her finger, she then takes aim at the wall nearby. As she does, the calcium in her fingertips begins to build up. They begin to build to such a point , that the finger bullets fly out of her finger, spiralling towards the wall, drilling into it. As she does this, she manpulates her calcium and chakra into her fingers again, this time rebuilding the bone into place.Now, I want you to perform it and ask any questions you may have about it.![]()
Alright understood no further questionsWell, the fingertips are shot off and they begin to spin rapidly, much akin to rotation.This allows them to drill into things they hit, creating a drilling effect as they pierce through items.
Applying the same method before, channeling my chakra into my calcium desposits, I quickly form the bones from my shoulder, removing the bone from its place, and using the chakra build up calcium to push the bone forward down my arm. As I do this, I release the bone from my palm and grabbing thee bone, creating a bone sword. As the bone is created, I thrust my arm forward, stabbing my bone sword into the tree in front of me.(Teshi Sendan) - Ten Finger Drilling Bullets

Description: Using the Shikotsumyaku ("Dead Bone Pulse") the user is able to fire their distal phalange(finger-tip) bones as bullets. As the bones fly through the air, they will rotate and drill into their target once they make contact. Because of the Kaguya Clan's fast regenerative abilities, the rate of fire from and supply of bones can become limitless.
Now, that's one of the most basic jutsus of the clan and is the basis behind most of the ranged jutsus (though these ranged jutsus are primarily customs are there aren't many that are canon, really just two). Now, let's get to the basics of close ranged Shikotsumyaku jutsus. Now, using the same core concept behind the Ten Finger Drilling Bullet, I want you to grow a bone from your hand that you use as a sword to pierce through this tree in front of you. The main difference between this and what you did formerly is that with this, you don't release the bones as bursts and instead hold it.
Reapeating the same process, Wendy takes her time again, channeling her chakra into her bones, causing the bone this time to become much more harder then before. As she does this this, she pulses the calcium deposits in her shoulder and pushes the shoulder bone forward and out of her palm, to which another bone quickly grows and retakes its place. Just before she releases it, she channels more chakra into it, making sure it is hard enough. She then takes the bone out her palm grabbing it and pushing her right foot forward, she thrusts the bone sword into the tree again, this time making it stick in place and piercing the tree trunk.*bone breaks on the tree*
You need more calcium and to ensure that the bones are solid enough to be durable and useful. Try again.
