It was Zhang Tie's first time to experience the method of an immortal emperor since he came to Motian Realm for such a long time.
Leng Manxue had already warned Zhang Tie to be alert about Star Emperor; therefore, Zhang Tie was also meticulous.
In Zhang Tie's opinion, Star Emperor could only take advantage of demon generals in two aspects: first, let those demon generals to arouse a big trouble in Dragon Emperor City after their iron cabinets were opened; second, after meeting Zhang Tie, demon generals would pass the image of the culprit of this trade to the side of demons, incurring a big trouble from demons.
Therefore, when each batch of demon generals arrived there in iron cabinets, Zhang Tie would always confirm that those demon generals had lost their resistance and didn't carry any hazardous objects; especially tools that could pass messages such as jade plate before starting to break and refine their chakras.
