History
After the demise of
his father, Gohan reflects on the power he wields and so he devoted himself to scholarly research on the source of that strength,
ki. Gohan begins researching the martial arts of the past, organizing them in his book
Groundbreaking Science in Age 804. The book quietly gains popularity and one of the articles, "
Katchin Can Be Cut!", has an immense influence in the birth of the Swordsman class, as it leads to the creation of Trunks and Goten's
Kikoukenjutsu Sword School in the year following the book's release. It also leads to
Krillin and
Tien Shinhan starting up their own training schools in
Age 821, the
New Turtle School and the
New Crane School respectively. As a result, by
Age 1000, many
Earthlings have taken up advance martial arts and understand
ki control.
