Lost in the Kunlun Mountains (2022)

Smart strong leading characters, lots of fighting, all are children of important leaders, Female leads are both orphans who have another identity, male leads are investigating something, there are multiple different sects for both shows, they are on an adventure to finding out secrets...

XuKai is also the ML here. Both are during the 1900s era.
Lost in Kunlun is more like an action/wuxie style with the story about five sects and Jiang Hu but AMA is more lighthearted (at least the beginning) and with the story about the military school life.
