Su Ping proposed virtual pet fighting to them because he didn't want them to get bored.
This world's virtual pet combat was no different from playing mobile games together with friends in Su Ping's previous life; it was a popular entertainment option among the battle pet warriors and could also hone their battle skills.
Asking his employees to play games with the customer was being as welcoming to his customers as he could be.
It just so happened that his shop had just been upgraded. The virtual pet arena—as a newly-added module—allowed players to fight using their battle pets in the virtual world.
Players could scan and import their battle pets to detect their shortcomings during battle. They could also practice with others who had battle pets with the similar stats, in order to increase the battle pet warriors' commanding and fighting skills. Nobody would be hurt in the process.
