Chapter 19 is the last chapter of the day. I need to spend some time thinking of the next part. Kalan got around 2 years to explore space. What he's looking for is opportunities. Like strong opponents to fight, advanced martial arts to learn from, forming his own base with various races that could worship him for Origin Energy or scientist to help him with building highly advanced technologies which would be of use if you manages to save the Saiyans as they would be deprived of high technologies once they break free from Frieza as they were supplied from Frieza in the first place.
Feel free to comment your ideas which I might like and add into Kalan's explorations!!
