Jiang Tang initially followed Su Chang'an's guidance to rescue and kill people.
Later, he directly asked the Marquis to have their people say if anyone had been left behind.
The Marquis asked those tribe members, who were imprisoned in a place that had no communication with the outside world, and they did not know where other members of their tribe lived.
Only among the sold girls were one or two from different places; seeing that their relatives were not the ones being rescued, they worried about their own family members.
When the Marquis inquired, these two girls timidly raised their hands.
"My home is in a valley where there is a diamond mine."
"My home is in the Wealthy District, where all the rich people live."
The Marquis could only ask them to describe the map of the place because they had flown high above and could not have possibly covered an entire country.
With the descriptions from the two girls, the Marquis drew a map and handed it over to Jiang Tang.
