"Courtyard Communicator? What's that?" Jiang Yuan was momentarily confused by the rewards for the new main quest, but anything produced by the system is definitely not bad.
It was probably similar to a communication base station, placed in the courtyard to allow everyone to conveniently "make phone calls" at any time.
Since upgrading to a Level Six haven was still a distant future, he didn't worry about the communicator issue. Instead, he turned his attention to the new building that appeared as the progress bar finished and the grey mist dispersed—a greenhouse!
The system's traditional style was still present, taking up a small area that occupied nine grid spaces on the haven thumbnail, just like the house, Floating Market, and Treasure Forging Workshop.
