Ten days passed away but Song Yun was nowhere to be seen.
The Emperor sent thousands of soldiers to search all over the Imperial city; the six clan leaders, who are governing the provinces, were also notified of the matter; Mark was also notified of the matter and was offered security for Song Yue and his siblings but he refused it.
As the Emperor took this matter seriously, he called out for an all-out investigation as a seven-circle realm expert in on the loose. The Crown prince and his allies wholeheartedly supposed it, fearing that Song Yun might try to take revenge on them.
The investigators interrogated Song Yun's relatives, questioned Mark and Song Yue, Cheng Xiao, Elders of Song Clan, and everyone that Song Yun but the investigation yielded no results. Even the super powerful spy organization, "WEB" couldn't trace his whereabouts.
