After the lunch service, Mag and the system discussed retrofitting the restaurant.
The basic style would remain, but they would change the electrification products to localized products. The omniscient door would be removed and oil lamps that could continue burning for a long time would be installed.
Underground City hadn't given him a clear reply yet, but a long period of silence meant that the other party might send a being that was more highly-ranked than Xi to Chaos City.
Mag had already displayed his power, so he wouldn't be surprised if the other party sent an Extraordinaire powerhouse over.
The system's technology was lower than Underground City's, so these little things of convenience should be kept away for their best interests.
Otherwise, he would be subjected to a very weird level of technology.
