SPOILER ALERT: This is a topic for discussion of plot progression of LOZH, so please do not read if you do want spoilers. 

The Legend of Zang Hai (LOZH) has aired 28 out of 40 episodes or 70% of the complete series and the ML has sought revenge on Marquis Pingjin, one of three people who caused the annihilation of his family ten years ago. The second perpetrator Eunuch Cao is also likely dead or dying. The last perpetrator remains hidden and the mystery of the Masked Man and Gui Seal remain unsolved.. 

What are your wild theories for LOZH? Who is the third perpetrator? Who is the Masked Man? What are the Gui Seal and undead troops? Let's try to piece together the story.

In an attempt to piece together the story, I rewatched some prior episodes and compiled below some key info that might have been overlooked with each new episode and revelation: 

1. Episode 1. Right at the start of the series, ML's dad had been supervising the construction of Fengshan Altar at the borders of Dayong and Dongxia for 3 years, and at the same time supervising the underground digging,  searching for Gui Seal, on the instruction of the Dayong Emperor.

  • He asked his assistant on the underground situation and when updated that the soldiers had dug more than a thousand foot deep, he said that should do and told the assistant to tell the soldiers to stop digging. Meanwhile underground, the soldiers had uncovered a deep pit, and something must have been released from the pit, making the soldiers unconscious. ML's dad went into the pit with his assistant and saw a maze-like chamber with an upside down pagoda, and a shining green object inside, and sinister troops seemingly guarding something precious.
  • Marquis Pingjin was stationed at the borders for 10 years, and had lost to undead troops before he finally defeated Dongxia, and the Emperor must have known about the presence of the undead troops and the Gui Seal. Also see point 4 - The Emperor's father was killed by the Gui Seal. 
  • The Gui Seal belongs to the Dongxia Kingdom, and the Dongxia imperial folks should know how to use the Gui Seal.

2. Episode 1 - Opening credits. Did you notice the sequence of the cast list and find any peculiarity? Dongxia Queen was listed 5th, right after Marquis Pingjin (4th), and ML's mom was listed 7th, right after the Dayong Emperor. Dongxia Queen has not appeared and ML's mom's appearance was brief in the 1st episodes and in flashbacks only.  A picture of the Masked Man was also shown in the cast listing, following by the ML's dad. Dongxia Queen, ML's parents (especially his mom) and Masked Man should be crucial for the remaining plot. 

3. Episode 3 - Puppet show. Current Dayong Emperor has no son. His father, the late Dayong Emperor was buried with the current Dayong Emperor's mother, Lady Li. The recently deceased Empress Dowager has a son Linzi Duke who is still alive, had been stationed at the borders, and would like to return to the capital for his mother's wake. I dont recall seeing his appearance. Could he be the Big Boss behind the Masked Man?

4. Episode 20 - Yongrong Duke. He is the brother of Dayong Emperor, and knows the existence of the Gui Seal, and  he said that his father (late Dayong Emperor) was killed by the Gui Seal.

5. Episode 21 - The female storyteller, FL's best friend, is the daughter of Zhao Bingwen. She has helped ML when Zhao Bingwen suspected ML's motive when he found him in his study room alone. Zhao Bingwen is unlikely the Masked Man. But it is not clear why his daughter helped ML.


With the above points, it should be safe to conclude the following are after the Gui Seal:

1. Marquis Pingjin

2. Eunuch Cao, in collaboration with Dongxia Queen, only because he need a powerful backer, to remain powerful. His current power comes from the current Dayong Emperor, and this Emperor does not have kids.

3. Dongxia Queen - The Gui Seal belongs to her, and she knows the secret of the Gui Seal and how to use the Gui Seal. As she has not appeared, it is unclear if she harbours thoughts to revive the Dongxia Kingdom with the Gui Seal.

4. Dayong Emperor - Could he be searching for immortality from the Gui Seal, since he does not have kids?

5. Linzi Duke - He is the son of the Empress Dowager, but he is not the Emperor and only the Duke and had been stationed at the borders. He could be harbouring thoughts to use the Gui Seal to command the undead troops to overthrow the current Dayong Emperor.

6. Masked Man - The fact that he masked himself could be he is someone well known or of certain official status and does not want to be recognised. He could be using the ML to help him get rid of Marquis Pingjin and Eunuch Cao,  It remains unclear his motive for finding the Gui Seal, but could be someone working for Linzi Duke?

More revelations in the latest episode, Episode 30, with more details of the Gui Seal and the past generations :

  1. Dongxia Queen's mother has used the Gui Seal in her war with Dayong (led by the late Dayong Emperor), with devastating consequences, though she managed to defeat the Dayong troops. Like the late Emperor Dayong, she also was killed by the Gui seal. She hid the Gui Seal and instructed  Dongxia descendants not to look for the Gui Seal. Dongxia Queen herself did not know where the Gui Seal was hidden.
  2. When ML's father was at the borders supervising the construction of the Fengshan Altar, he rescued Dongxia Queen who was injured by Dongxia rebels. ML's father nursed Dongxia Queen to good health and sent her back to Dongxia.
  3. One day, ML's father finally found the Gui Seal. He has either brought the Gui Seal back to Dayong Emperor to complete's Dayong Emperor's mission for him, or he has hidden it after Dongxia Queen shared point 1 with him. 
  4. Dongxia Queen has two daughters i.e. FL has a sister, who has yet to appear.

Latest possibility:

 Wish Upon A Star:
2. Eunuch Cao, in collaboration with Dongxia Queen

Eunuch Cao collaborated with FL's sister, and not Dongxia Queen, as (1) Dongxia Queen appears clueless to who Marquis Pingjin and Eunuch Cao are, and (2) FL's sister might have witnessed her grandmother's passing and is planning to revenge using the Gui Seal that belongs to her Dongxia Kingdom. 

This thread is an interesting read love it

I think the 3rd culprit is the masked guy. Like he is winning every thing by making Zang hai doing every thing and find the Gui Seal for him. But we still don’t know his identity. I think the masked guy is maybe the late supposed emperor and that the gui seal cursed him and did not kill him. So he want to find the gui seal to undo the curse and die ? Like he some type of zombie this is why we don’t even see his hands ? Like he could remain conscious? Because he was the last one to really ?
