After the 'explosion' all three of them were knocked out and thrown clear of the initial site. By some miracle the Grand Priestess managed to use her lifesaving treasure to protect herself at the last second otherwise she too would have been wiped out of existence along with an entire section of the forest.
When it was clear she went up to each one of them to see if they were alright. Both Ma Jiang and Princess Ceni were covered in thin golden barriers which disappeared within minutes but Hao Xuan's remained for a long while after.
She moved him to the only safe place she knew, within the mountain walls left behind from olden times. When his barrier finally vanished almost an hour later he woke up instantly but his mind was elsewhere.
The curse of the sisters of fate was not something he could easily break out from by himself.
The chaos leaked from his body creating the harsh environment Jin Wang saw 3 days later.
