|Chongtong(Cannons) and Chongtongjeon(Arrow Projectiles)|
After the gunpowder was introduced at the end of Goryeo Dynasty,
we began to see the extensive development of a much more advanced form of arrows.
Particularly, in the age of King Sejong in Chosun Dynasty, many arrows thrust by gunpowder, from Sejeon to Daejangkunjeon, were developed.
Accordingly, cannons, from the smaller Sechongtong to the larger Cheonjachongtong, were invented to fire these arrow projectiles.
There were also others such as Sajeon, Paljeonchongtong, and Singijeon all able to deliver volleys of arrows at a single shot.
The gunpowder used at that time was a black powder made from the combination of acetic acid, sulfur, and charcoal.
Turtle-shaped portable powder flask also made an appearance.
