Douluo Continent is a deeper fantasy-based version of Fights Break Sphere. The genres are one in the same, but Douluo focuses on spirits while Fights Break Sphere focuses a lot more on the martial arts. They're plotlines are very similar, both involving an evil "Soul Hall", and a similar story of teamwork and self-discovery. There is also that aspect of romance within it, with that same sibling dynamic in Tang San and Xiao Wu's relationship that Xiao Yan and Xun'er share. Both are lovely watches, and if I were to have a say, I would say Douluo is the better produced drama. The CGI is actually unbelievable compared to many other fantasy Chinese dramas.

Douluo Continent has 2 very charismatic and talented leads as Fights Break Sphere did, and one of them is Sean Xiao Zhan as Tang San, who originally portrayed Lin Xiuya in Fights Break Sphere. Hope that helps and you choose to take on this other amazing drama!

Before The Untamed, my first ancient Chinese drama was Handsome Siblings. Going into The Untamed, I notice that the dynamic of soulmates Wei Wuxian and Lan Wangji were very much alike to the brotherhood of Jiang Xiaoyu and Hua Wuque. The red and blue, black and white relationship, I like to call it. There are vast diffferences in the dramas, but that same plot of discovery, connection, and love (in different ways...) are portrayed in the two dramas.

The Untamed is an ancient xianxia drama, which is much more fantasy related with talismans and stuff. Handsome Siblings on the other hand is an ancient wuxia, but both dramas share similar plotlines of "who is the real villain", and finding out how a little bit of dependency on each other is important. The characters are all charismatic in their own ways, but as mentioned before, a similar dynamic is present. I enjoyed both very much, so I hope this is helpful!
