Soul Hook Ma Mian's expression changed dramatically upon hearing Shen Luo's words, his mind anything but calm.
That year, when Jing River Dragon King imprisoned Emperor Tang's soul, he had personally taken part in it and knew the details quite well. The Dragon King's daughter later joined the Demon Clan, suggesting a likely connection between Jing River Dragon King and the demons, and that mysterious figure who worked with the Dragon King was certainly not benevolent and was possibly part of the Demon Clan as well.
Shen Luo had just inquired whether there were Demon Clan infiltrators in Yama's Palace during the disaster of demons, and his implications clearly leaned in the same direction.
"Thank you for the reminder, Friend Shen. This is extremely important. I will relay the message to Lord Zhong Kui at once." Soul Hook Ma Mian had these thoughts flash through his mind as he bowed deeply to Shen Luo and took out a Black Jade Tag, about to trigger it with a hand seal.
