The Grey-faced Buzzard left Constlac's port very quickly.
What Gu Ding did not know was that after the people from the Army had retreated from the desert, various other forces also left the desert where the superweapons were buried.
Most of the forces ran straight for the port, wanting to leave the planet at once because they knew that there was a chance the Army's mission would be called a fiasco. The Army people would probably take action, the moment the explosion was over, tidying up the remaining other forces to make it look as if they had not failed their mission so badly. The Army people would then give the Federal Government an explanation. The other forces did not want to be tidied up by the Army, so escape was their best choice.
Gu Ding's three escape capsules were very quickly discovered by the Army people at the edges of the desert.
