Gu Jie's specialties included techniques for creating "Sorcery Boosters",
magical devices that utilized humans as the components, a technique for
creating human tools such as "Generators", and "Necromancy" that
allowed him to manipulate corpses. He was also skilled in the "Surgery
of Perpetual Youth." However, he could only preserve 'apparent'
immortality and not actually extend one's lifespan. Gu Jie developed
these immortality techniques at the Kunlunfang Institute, and this
surgery was one of the reasons that the ancient magicians were banished
from the Kunlunfang Institute.
