You should know that the Eastern Dragon Empire had already abolished the title of empire, and Qin City was merely a territory. By establishing diplomatic relations with it, the Milan Empire essentially acknowledged its completely equal status. At the same time, Silvio even announced that he would provide Qin City with a vast amount of various materials yearly, all at half price.
Qin City's own production capability was enough to be self-sufficient, and with the support of the Milan Empire, there was no need to worry about any resource issues. What made the leader of the Eight Eastern Dragon Clans and the Elders most happy was that the Milan Empire had been sending over black-haired and black-eyed people with Dong Long bloodline, and their numbers were continuously increasing. The Burna Mountain Range was spacious enough, and the great name of Qin City also meant that these descendants of Dong Long no longer needed to worry about their future.
