Season 2 of No Boundary is a direct continuation of Season 1, and the quality is very much the same. Nevertheless, I sense some difficulty in sustaining the story for another 20 episodes so that Season 2 would be long enough.

I think Season 2 continues from Season 1 very well at first. The part until Duanmu Cui and Zhan Yan manage the get out of The Abyss (a parallel universe that is based on Duanmu's memories) with the antidote for the toxic aura is excellent. After this point, however, the story falters a little. A dead character like Wengu is brought back to life, but it seems all to easily done, and it also seems to be for the purpose of having a prominent demon-clan character in the story again (because there's something about immortals, mortals and demons having to unite later in the story).

The villain who gets trapped in The Abyss also escapes a little easily. Oh well, if he doesn't escape, the story will end. But things also get a little over-the-top here as the villain infiltrates and takes over the heavenly realm of the immortals. It is rather intriguing, however, as a critique of authoritarianism. As the evil tyrant takes over the immortal, mortal and demon realms, he basically puts people and places under pervasive surveillance so that he knows what people are doing and whether his orders are being carried out. From what is at first a somewhat noble desire to improve things, the villain's descent into total villainy (while justifying his deeds as being for the greater good) shows how the lure of power corrupts and how hollow the justifications for authoritarian tactics are.

Despite being so powerful after gaining immortality, this villain also suffers from the headaches that plagued him as a mortal. In fact, they get worse, and these headaches are sometimes timely enough to prevent him from performing more evil deeds.

The plot development in Season 2 isn't as impeccable as it was in Season 1. Still, it is not so bad that it really affects the issue in a major way. The love story between Duanmu Cui and Zhan Yan is also given a nice, happy ending even if it is a little forced. One does, however, wonder why the people who saved the world a thousand years ago were conferred the status of immortals whereas Zhan Yan who has done no less to save the world from an evil immortal devil-dictator is just left to die, requiring Duanmu Cui to do something really drastic to resurrect him.

A flawed but still excellent continuation of Season 1, this series does manage to satisfy in many ways,
