I think he wanted to go back to the past to visit his friends one more time, to see how they live, because he disappeared from their world not knowing how it all ended.
In the end, Liu He uses the Qilin to transport Wang Heng back to the 21st century to save his life at the very last moment, and Wang Heng wakes up in the 21st century after several weeks in a coma. The emperor does not allow Liu He to return to the capital but orders him to go back to Haihun. De Jiu dies (i think) fighting against the enemy (because when Wang Heng disappeared from her world, she no longer had any other purpose). When Liu He’s health deteriorates, he takes the Qilin and transports himself 2000 years into the future because he wants to see Wang Heng again. And he does meet him — but time wasn't precise so Wang Heng was still a boy. Happy to see him at least in that way and to witness the world he comes from, Liu He gives him half of the Qilin (this is the half that Wang Heng is holding in episode 1) and disappears form his world.
When Wang Heng wakes up from the coma, he goes to a museum and sees objects there that he once used with Liu He. He remembers the riddle that Liu He had left him about the secret location and goes searching for the place indicated, only to find that Liu He had left him the other half of the Qilin in a box, so that 2000 years later Wang Heng could discover it. Wang Heng then joins the two halves of the Qilin, activating them — and thus the drama ends, with a semi-open conclusion.
It can be called a happy ending. Actually, I would say that it was a bit unexpected, but considering the story, it was good and positive enough. (I think about the ending of S2, because S1 is uncompleted without S2)
Among all the characters, Xu Qingge is still my favorite. Normally, I prefer strong women, especially if they have martial arts skills, but this time Qingge was the best female character for me. I rarely see someone so ordinary yet intelligent, simple and beautiful (a plain dress, not much jewelry, but still so harmonious and refined), and at the same time loyal, with a good sense of humor when needed, caring, and faithful, like she is. For me, she portrayed her role excellently — the actress played her wonderfully, and I liked her much more than the FL.
Out of all the female characters, besides Mo’s girl, my favorite is that friendly girl from the Beast Mountain Sect. She might be a little clumsy, but at least she’s honest, simple, down-to-earth, and genuinely cares about others. I really hope we’ll see more of her in the upcoming episodes. It would be a shame if she were to die in that war.
I have tried to watch this, really, but it's so bad. Scenes aren't well connected; you have the feeling that something is missing and that a lot of scenes are cut out... Even the story is not interesting enough to motivate you to watch it to the end... I tried, but failed...
So far, I like the drama, the acting is good, but I honestly hope that the ML won’t be dying from poison for the next 30 episodes just because of the FL’s stupid mistake at the beginning. It’s already getting tiresome that in so many dramas, the FL/ML is poisoned for the entire show, and the final episodes revolve around finding an antidote. This could have been a brilliant detective drama, but it’s a shame that the (initially strong and skilled martial artist) ML is now a weak, dying detective who constantly has to worry about his health…
I love that all the characters are unusual, especially that the male lead here is the complete opposite of the typical extremely intelligent and handsome male leads. I like that you can see the growth of each character and the changes that friendship brings. The whole drama is humorous, and although it's a bit irritating at times, I would recommend it because, despite its simple plot, it carries beautiful messages.
