This scene is actually not difficult. It's also the last scene of the entire film, where the male protagonist has obtained evidence and, together with his teammates, deeply infiltrates the enemy stronghold to meet the female protagonist.
The earlier dialogue scenes have already been shot. Logically, the action scenes should have been shot immediately after, considering the difficulty in setting up the scenes.
But Director Ji, due to the previous incident with Zhang Fan getting into trouble and Xia Siyu getting injured from jumping off a cliff, decided to shoot the dialogue scenes first before the action scenes, especially since the action scenes are quite challenging. Setting up a stage in a foreign location doesn't cost much, and it requires selecting some extras, considering the filming is overseas, which takes time.
