Upon receiving Yun Chi's secret letter, Mei Shuyu immediately dispatched people to investigate the confinement area of the King of Nanjiang and discovered that the King of Nanjiang had gone missing. He was shocked and promptly initiated a thorough investigation while sending a carrier pigeon to Yun Chi, informing him of the King of Nanjiang's disappearance.
Not long after his message was sent, he received a reply from Yun Chi, ordering him to arrange all military affairs within the camp from the day he received the letter and to set off for the Capital City immediately, as Lu Zhiling was already on his way to Nanjiang.
Mei Shuyu had not expected Yun Chi to summon him back to the capital. Yearning for Capital City, he quickly set his affairs in order and departed without delay, riding at full speed to return.
Midway, he encountered Lu Zhiling, who was en route to the Southwest Territory.
