Les Neuf Mystiques (2016)

Police officer Pang Hong Mei amid the many obstacles created by U.S. and Jiang spy agents, rescued Ji Danyang, a patriotic scientist who returned from the United States from the enemy spy. She accompanied Ji Danyang to Lumen City to participate in the "Water Drop Project". Enemy special forces formulated a sabotage plan codenamed "Operation Rock" and concentrated their forces and tried to destroy the "Water Drop Project." Pang Hongmei and Ji Dan Yang fought a life-and-death battle with enemy agents in Lumen, thwarted the enemy's conspiracy, protected the "Water Drop Project" and finally achieved the expected success. The couple who went through the test of life and death, also realized their dreams and firm ideals.

This show is actually the prequel to the Lost Tomb series. It's where the formation of the Nine Families that are mentioned in the series, even though some of the characters aren't exactly like those in the rest of the series.

both about a group of youth that investigate crimes/mysteries. Both set in a historical period, tho young blood is set in a much earlier time period.

Mystic Nine isn't set in a military academy and has some fantasy elements but appearance wise the male leads give off the same vibe except Fo Ye in the Mystic Nine is super smart

- The main couples has a similar dynamic (funny and cute) when they are on screen together
- they are both set in the same time period with the Japanese taking over China
- there are a lot of good looking actors in both shows

Military drama set in Republican era
Male Lead and Female Lead love progress slowly
There are some Beijing Opera element on it

The Mystic Nine is the prequel of the The Lost Tomb series. The time period is 50 years before the main event, so all the characters are different.

both dramas happen around the same time period of the japanese occupation, also they share the same westernized modernized costumes and the settings...

The Mystic Nine ends at the same time the Battle of Changsha starts. The Mystic Nine takes place a few years before the first battle of Changsha and is centered around tomb raiding. While these two dramas are unrelated to each other in terms of plot and genre, if you want to watch something after The Mystic Nine that is in the same time period, then you should watch Battle of Changsha.

the mystic nine is about original nine families and how whatever happened before led to what wu xie and zhang qiling had to deal with now.
