Master Zhang returned back to the waiting room after around 5 minutes. During that time, he had asked a junior disciple to go to a nearby supermarket to get the ingredients needed to create the magic array while also arranging for the operation of the dojo for the next few days, allocating the various tasks towards the teachers so he would remain free during the time of our supernatural operation.
It is also quite lucky that the Zhang Clan is a well destinguished and well connected clan, so even though we were located halfway across the globe from the clan's headquarters, Master Zhang still managed to get a few specialists to come over from the East after a few calls. Due to the time difference between the East and West, the masters would be able to arrive here on the same day, since the timezone here is half a day behind. Therefore, it is predicted that all the preparations would be finished by tomorrow morning in the latest.
