Dror didn't have a choice but to prepare to return, but he still had a day and he was prepared to utilize it to the maximum.

As the night arrived he went to the six locations in the outer sector of  the central city, to tweak and modify the communication equipment left behind by the ancient civilization.

After doing this for many times he had become really proficient at this, but still he was extra alert as he was inside one of the central cities and that too ruled by one of the most fearsome of the 7 families.

To his good luck he was not discovered  and when it was the next morning he left for the Earth base.

He used the fast train which connected  to the outskirts from the central city Ranbath to cover a large distance, then by using earth skip he traversed the rest of the journey.
