Before the nuclear explosion at the edge of the space elevator.
An unnamed hero lay prone on the ground, slowly crawling up a gentle slope, then the observation instrument fixed on his shoulder quickly leveled, rotating a few times to determine his own coordinates.
More than ten seconds later, the young hero determined his relative position to the original coordinates. He cautiously moved 2.5 meters to the left, then disassembled the fixed stand from his leg, inserted it into the ground, and set up the instrument. The instrument was smeared with pebbles and dust, nearly blending with the environment.
He took about ten seconds to complete all this.
"Hey, why so careful?" Below the slope, a tall hero looked helplessly at his junior's performance, "If you didn't mess around with all that, we would have finished ten minutes earlier."
He was leaning against a tank with a very low turret.
