It is 10/10. Solid in every aspect of story telling. Although it follows typical successful wuxia tropes, it doesn't lose originality, novelty, and poetic quality.

It follows a similar pattern we saw in dramas such as Nirvana in Fire (2015) and The Blood of Youth (2022) which focus the story on one central figure, the tragic hero, and his struggle to find the truth. Mysterious Lotus Casebook (MLC) starts from a downfall and ends with tragedy. We starts from zero and in the end, all return to zero again, creating a full complete circle. Our hero lost everything: his power, skills, fame, status/ position, and friends/ followers. He was defeated by his enemies and by his own mistake. When he was in a grave danger, a bikhu saved his life and he was reborn. He found new purpose of life and lived a humble and wiser life with new identity and changed personality. Everything is seemingly normal again, but a scar from the past forced him to return to the jianghu and involved in the conflicts. He found new friends and gain various supports to fulfill his mission. He was successful after so many hardships. He regained his former glory. However, his righteousness drove him to the path of self-sacrifice for the greater good and for the people he loved. In the end, he let go everything with a content heart. He died peacefully, and was loved by everybody.

The strongest aspects of MCL is first, the characterization of the main character, Li Lianhua. His development is so clear and flows naturally. We easily understand why he become or does this and that. He is a very positive and mature person who learns from mistakes and gains wisdom. The past is not turning him into a person with psychological issues. He is without emotional baggage so that he is able to stay firm when confronting people from his pasts. When he was confronted by his past lover, Qiao Wanmian, his sadness is there, but he stayed level headed. When watching this particular scene, I was so afraid that the story would follow the romance tropes where the male cannot resist his feeling and rebuild the romantic relationship. Or, during the marriage scene, the male usually is burnt with jealousy, and use the only chance to cure the female, to show romantic gestures. Gratefully, it is not. Other thing is the consistency from the start to the end, not only for Li Lianhua, but also for the other male main characters. Their personalities are different to each other, but their relationship is so harmonious, thus enjoyable to watch. They don't make stupid moves and every act is effective.

Second, the amazing plot twists. MCL is the drama that should be watched patiently with open and clear mind. Don't rush to know the ending of each case and of the overall story. Protect your viewing experience from spoilers, because it definitely will ruined the twists and thrills. The first part of MCL (episode 1 to 20-30) are basically detective story. They are solving mysteries by following clues and leads. Not knowing or understanding many things in the beginning to the mid part of the case are normal to bear, and in the end we will certainty get the explanation. Just wait and see. The drama is very skillful at when to close and disclose important information for the viewers. We, viewers, are "cheated", believing false truth, and by the time everything is finally revealed, it feels shockingly great. It is really not like most dramas that place viewers as know-all-things so that we are becoming impatient watching clueless characters in screen. The drama is very careful at telling the past events and the flashbacks are contained in character perception or memory. So, we understand the story from the character's interpretation of that event. Meanwhile, the past facts are told through dialogue between characters, documents, and relics.

Third, the mixed genre is so good. It is a wuxia that is laden with action and sword plays. It is a tragedy, but full of comedy. However, it is also a mystery story with a suspense, horror, and gore. When they are exploring a tomb, a cave, underground facilities, or a body of deceased, with minimal lights, it is so scary. When they meet the zombie, ghosts, and the beast, my heart beats so fast. This drama has balance day and night scenes. When it should be scary, it is set at night. When it should by funny, it is on broad day light. It has romance (mature love), brotherhood, family, and companionship. It has moment of togetherness and adventure as well as a moment of solitude and self-reflection. The evil people are evil without white washing them with "good" humane motive. The jealous person is jealous. The greedy is greed. The crazy is crazy. No excuse. No feeling sorry. We don't mix the good and the bad. The previously evil or bad person becomes good in our eyes after they experience certain events in the story, not because of the subjective experience or pitiful past that begs our sympathy. It is good for us not knowing about the royal story behind why Jiao Liqiao is crazy, why Shan Gu Dao is jealous and cruel, etc. It is on their character, not circumstances. They are bound to received punishment as their retribution/ karma.

Those are things that make this drama stands out, IMO. I don't find any serious weakness. Of course, sometimes the CGI is not perfect, the performance is somewhat a bit lacking, the mobile house is weird (look small from the outside, but spacious inside), etc. We can overlook those and enjoy the story itself. It is so good, lets watch and re-watch!
