Map of The City

Fang Chen has just learnt that there is a city which connects all Kingdoms and the empire and before going to The Empire all people has to go to that city.

But he couldn't understand why Tian Cai didn't know about this city because the way the elder was introducing the city Fang Chen immediately knew that the city was very large compared to the Kingdoms and and he will be able to earn huge amount of spirit stones as all of the people with higher cultivation then go through that city. 

But when he thought Tian Cai has not left kingdom for single time it is understandable that he doesn't know about the city. 

He Completely ignore about Tian cai and focused on the Elder because the elder was continuing to introduce the city to him.
