Ze Tian Ji (Fighter of the Destiny) is based on a Web novel having the same name written by Maoni. They have produced not only TV series but also an animation too. Animation's name is also the same, Ze Tian Ji.
The story is quite impressive and it's so good. And also it's so long of course. But when they make it into TV series, they cut some parts and make it shorter. As a result, some things doesn't make sense and difficult to understand if you don't know the whole story.
Compared to the animation, this TV series is inferior to the animation. As I've said in above, some important parts are missing and so, it's quality becomes lower than animation. On the other hand, they added things which are not in the novel, so, you can see something fresh. You might like it if you are looking for something different from the original novel.
The main character, Chen Changsheng is very cold, serious, honest, firm and calm. But Lu Han seems to be kind of not fit with the character. He's not calm as the character from the novel. If you watched the animation, you'd see the difference. Chen Changsheng from the animation is better.
All in all, although this TV series really has so many flaws, but the performances are basically fine and special effects are good too. It really can't compare to the animation, but it still works and I kind of liked it for a certain period of time.
