After watching the whole movie, I re-watched it again, hoping to understand more things, and I found something.
About 35 minutes into the beginning of the film, when the male and female protagonists are chatting near the signal tower after they speak their tongues, pay attention to the upper left of the center of the screen, and you will find that the screen flickers at first, please pay attention to the higher mountain at this time. The shadow location, and the signal tower aside a small bump in the ground.
During their conversation, when the screen flickered, a small snowdrift suddenly appeared on the bulge. After about half a minute, the so-called movement of two objects that many people saw appeared. The monsters that appear in the back, I tend to be the latter. In short, the two objects ran behind the snowdrift that suddenly appeared.
Half a minute later, the picture flickered again. This is everyone's attention. The small snowdrifts are gone. The key is that the reflection of the mountain has undergone major changes.
Therefore, I came to several conclusions:
1. As long as the heroine's camera is flashing, the monster is nearby.
2. I can be sure that they did travel through time and space at this time, but I have not figured out how long it took. The second time I'm not sure, let's look again.
