I've read the novel but still will analyze the drama in its own way.

Plot: The plot of this drama is finely written but it required more attention and more emphasis on story development. Like over the period of 40 episodes the amount of knowledge and revelations are only a handful. None of the plot twists surprises you the most and does not leave a long-lasting impact on you. But it's never boring or slow-paced, the story progresses pretty fast and also has elements like humor, friendship, squad goals, etc.

Acting: I would all the actors were amazing in their given roles. They were the main strength of the drama who carried the drama throughout. Especially Xiao Zhan did it so well, portraying the right amount of expressions and emotions in the given scenes. Characters like Dai Mu Bai, Ou si Ke, Ma Hong Jun, etc have a special place in my heart. You'll get attached to each one of them.

CGI and Music: The CGI was top-notch, all the graphics including the action sequences were so much fun to watch, some even brought me to the edge of my seat. It was definitely mindblowing. The music was my biggest worry as it did not even suit the situation which was going on. The flute music still irritated me a lot.

My biggest conscience was I expected a lot from Tang San's character but we did not see much of his abilities and power being utilized, moreover did not feel his character was much developed in any manner, I feel they might have planned it to focus on season 2. Still, we've got a long journey to go as there are still many issues to be settled, many things to be unveiled.
Season 1 was a fun one-time watch. Do not expect anything just watch for the experience the drama gives.
