'Also, there are chances that he might be angry with me and want to kill me.'
Let's say Ajax found out how to contact the Ascended Cultivator from the Heavenly Bestial Realm using the Golden City, and that particular Ascended Cultivator was blood-related to Aveline.
Without a doubt, that particular cultivator could easily figure out that Ajax killed Aveline because that's the only way someone other than Aveline could use the Golden City.
Will the Ascended Cultivator still want to exchange things with Ajax?
Moreover, if that particular cultivator's relationship with Aveline was very close, then he might do everything in his power to kill Ajax.
Hence, Ajax thought that he could use the help of his two new subordinates in case things didn't go as he planned in the Golden City.
'Let's see.'
With that thought in mind, Ajax flew towards the Golden City while waiting for his two new subordinates to arrive.
