Xuanhuan: I Get the City Upgrade System from the Start

Xu Feng transmigrates to a fantasy world, where he receives a city called Happy City and awakens the City Renovation System.

From then on, a barren city is about to become the happiest city in all the worlds.

Empress of the Great Tang: "How dare you, Xu Feng! I rule over my own domain, and you still ban me from entering the city?"

Supreme Sect Master: "What do I have to do to become a guard in Happy City?"

Holy Maiden of the Demon Sect: "As long as I can get an ID proving I'm a citizen of Happy City, I'll give myself to Xu Feng and marry him."

Another version of the synopsis:

Empress of the Great Tang: "I want to see what magic Happy City has. Why does everyone want to join it?"

Supreme Sect Master: "My cultivation has hit a bottleneck. I must use Happy City's Cultivation Pagoda to break through."

Holy Maiden of the Demon Sect: "Why can the demonic urges caused by my Nine Heavens Holy Demon Art only be suppressed in Happy City?"
