The one he was worried about was neither Monarch Chang Sheng or Monarch Yang Zun. Who would harm Mu Xiantian but Zhong Yue himself!
After achieving the seventh secret realm, King Zi Guang started suspecting that a monarch was behind Zhong Yue. Zhong Yue's background was very vague and clouded, and King Zi Guang was unable to discern his intentions. Though Mu Xiantian's lady body was powerful, she was still not a monarch, and that meant that she was no match to that monarch lurking around.
If he left Mu Xiantian alone with Zhong Yue, he feared that Zhong Yue would kill Mu Xiantian!
As if he felt the gaze from King Zi Guang, Zhong Yue turned around, and a bright and warm smile appeared on his face as he said, "Senior Martial Brother Zi Guang, you should stop staring at me at my back, you are making me uneasy, it feels just like there is someone pointing a dagger at my back in point black."
