This story is dominantly about the character ZYZ. So, I wanted to talk about him and his involvement in the story for quite a while.
ZYZ is a character who shows numerous emotions and sides in this drama. He has spent tens of thousands of years trying hard to control his malicious energy drinking bitter jade water even though he doesn't need to eat or drink. He has seen and experienced a lot and grown world weary. His natural curious and playful nature wore down as the time passed. He has always been adventurous spirit with hint of mischoeviousness side yet being a kind forgiving soul. He would bring his childhood friend to human world to experience what humans do and feel. Trying his best to understand their ways and their emotions. It took him many thousands of years to learn human emotions, human emotions don't come naturally to demons.
His life took a fall when he encountered WZ demon experimentation base along with LL. Lilun very understandably was furious with humans. And started killing humans indescrimately poor ZYZ is very thoughtful person who cares deeply about humans and demons equally and understands that they both need to be treated justly. In an effort to stop LL he accidently hurted him with everburning wood. After the incident of him and LL falling out of friendship, it left him deeply scared and lonely. At this point he was loosing his will to live very fast, then incident of blood moon hit the final nail in the coffin. Wildreness starts fall apart because of goddess dying and half of baize token missing. ZYZ felt extremely guilty and hated himself yet he couldn't end his life because he was extremely responsible person. He meets WX looks after her but starts to like her while protecting her so he decides to hand her to place he can trust who will keep her safe and sound. Then he seals himself in his house so he couldn't be found and can't do more damage until he found out a right way he could have been killed that is by ZYC hands and his special sword.
He makes a team for the specific purposes of finding other part of the token, saving wilderness and solving human/demon mysterious cases before fulfilling his wish of getting killed by ZYC. However, things don't go his way, along the way as he interacts with team mates and the world he shows his kind, compassionate, humorous, humble, playful, mischievous, knowledgeable, wise, romantic, loyal, benevolent, funny, mighty and vulnerable sides to his his team mates. He ends up changing their view of himself and the demons and most importantly he falls in love with WX and become soulmate with ZYC. He has always admired WX for trying to learn and understand demons to empathise with them, as she is the only human who ever tried to do so. She understood his heart when everyone pointed fingers at him and alienated him. ZYC gave him understanding of loyal friend and comrad in arms in face of many challenges. Which changes the state of his heart and wears down his resolve to end himself. So he loves and cares for WX with a lot of restraint knowing he will have to die someday. Along with this journey he tries his best to be a good friends to LL and ZYC always fiding ways to help them emotionally and phycolgically. ZYZ being very wise and caring always tried to find ways to guide them them out of their specific predicament. He taught ZYC demons world perspectives and taught LL human world perspectives. Eventually got them to learn to meet half way at the line of peace between both races.Team starts to function as a family for him: loving and caring for each other and having fun while relying on each other even in darkest of times.
unfortunately all good things come to an end although this team journey was beautiful dream for ZYZ he was snapped out of it very rudely by fate. WZ when he started to take action on his evil plans to ruin the humans and the demons a like, many of his friends died. In order for WX to to fix all the horrible disaster caused by WZ, ZYZ has to step in to end his life even though he now doesn't want to die any more. ZYZ being kindest soul, forced himself to break his promises to love and his best friend. He sacrificed himself and resigned himself to his fate in this lifetime again. Although, ZYZ was ready to die as a criminal from the beginning he ended up dying as all time hero. His remaining family made sure to spread the truth and looked after what he cared about and uphold his values and the justice and maintained peace between two races his life long wish.
however this time fate was not as cruel to ZYZ as past life of Yinglong, with ZYC effort he saved ZYZ's shred of predominal spirit and ZY comes back to life to allow him to keep his promises.
So in my view, ZYZ is a very comprehensive, immaculate, diverse, awe-inspiring and lovable character. Even though he is a demon, people can understand and sympathise with his difficulties and struggles. He makes a unforgettable ever lasting impression and place in people's hearts 💕
