Yang Ping completed the separation of the brainstem and began separating the cervical spine, opening it effortlessly from the posterior side. This kind of surgery is the simplest for Yang Ping, who comes from an orthopedics background; it's the kind he performed daily in the past.
Opening the cervical spine from the rear revealed the cervical spinal cord. Separating the cervical spinal cord is not necessarily any easier than the brainstem; it's just that the consequences of failure are relatively lighter. Failure in brainstem surgery results in death, while cervical spine surgery failure leads to high-level paralysis. If it's too high, impacting the contraction of respiratory muscles, the patient's ultimate outcome could still be death.
