Zhao Hai took out some time to train these people. At the same time, he equipped them with some things that could be used on the battlefield, such as communication arrays and barrier arrays.
There was no need to talk about the communication array. It was mainly used to communicate during battle, making it easier to command. As for the barrier array, it was the same one that Zhao Hai and the others had used when they were in the bewitching Empire. During battle, they could open the barrier array and form a defensive barrier to protect them.
Of course, after these things were given to them, they had to be trained for a period of time. Even if they were not required to follow orders like the Army, they had to understand how to cooperate to exert greater combat effectiveness.
