The reason for strapping safety belts to the Black Knight was to serve as insurance since the Prometheus Spaceship was destroyed at the end of the movie.
Chen Chen was unsure if there was still anything useful at the coordinate or if the passage led to the room on the spaceship. There was a chance the passage would lead to a void in space or simply to the wreckages of the spaceship.
Contrary to Chen Chen's expectations, the Black Knight had returned from the opposite end of the passage in less than ten minutes.
Unlike previously, the Black Knight labeled T0421 was covered all over in a layer of grayish-brown dust as if he had weathered a sandstorm in the other end of the passage.
The Black Knight also brought back a recording with him.
"Minor traces of radiation detected!"
Little X immediately alerted, "Sir Godfather, please be careful. The dust particles on T0421 are radioactive dust."
