Disguise into the Secret Realm: a Treasure Hunt in the 1980S

The secrets of the deep mountains in the 1980s suddenly "echoed", relying not on maps but on disguises. Tian Zixuan and He Yaxi sneak into the expedition team to avoid being chased, but they find that the entrance is guarded by a set of agency rules that will "substitute people": every time the way out is hidden in a lie, the more they want to live, the more they have to act, and the more sincere they have to be, the more fake they become.
