author is using unreasonable assasination technique ... it's illogical
Author didn't learn about medical knowledge ; human anatomy, forensic etc....
let me tell you...
in the first 10 chapters, MC shifted to a fly. He stabbed the victim with a needle at the artery.
that needle has 0,2 mm in width and 1 cm / 10 mm in depth...
meanwhile the common carotid artery exhibited the closest average distance to the skin (23.5 +/- 6.9 mm) whereas the internal carotid artery exhibited the closest average distance to the vertebral body (7.36 +/- 3.8 mm, measured to the transverse process)
the needle could not reach the artery
you could see the picture
