It was none other than the use of a battle store via the Pandamonium app.
Through this battle store, cultivators can now buy food, potions, weapons, inscriptions and even accessories to aid them during their raid.
It was part of Jin's plan to improve the services he provided for a better dungeon experience. This would also allow him to create harder dungeons since the cultivators now had access to an online store in the midst of battle.
While it might be seen as a break in the traditional way of dungeons, Jin saw it as an opportunity that had yet to be fully utilised (or in some sense exploited). He was sure some dungeon suppliers might offer such feature before, but the System guaranteed that Jin's store app's user interface and services will be maintained top notch quality.
Thus, Jin named the Battle Store sub application within the Pandamonium - 'Pit Stop'.
