There was no clear connection between Sanguine Red's novels," Tengen " and " Tengen 1 ", which could form an independent series. However, judging from the name, Tengen could be considered a follow-up to Tengen 1 because Tengen was usually used to refer to the first work in the series. However, this was not absolute, because the name connection did not necessarily mean that there was a direct causality between the works.
"Kai Tian Record" was a fantasy novel written by Sanguine Red. It told the story of a race that was unwilling to be enslaved. In order to prevent his family from becoming slaves, the male protagonist began a difficult journey of cultivation and became a powerful martial artist. In the end, he led the race and resisted oppression. I hope you like my recommendation. Muah ~
