In his last words, Li Yao's foster father wanted Li Yao to surrender to the Imperium of True Human Beings when the Alliance of the Holy Covenant attacked them. He also asked Li Yao to look for a woman named Li Linghai in the Imperium, claiming that she would certainly look after Li Yao and even the entire Heaven's Origin Sector for old time's sake.
Li Yao felt quite strange about the plan.
First of all, his foster father was from the Covenant Alliance, while Li Linghai was from the Imperium. What exactly was the relationship between them that made his foster father unable to forget her when he was about to die and believe that she would certainly take care of his offspring?
Secondly, who was Li Linghai in the Imperium exactly? Was she powerful enough to decide the fate of an entire Sector?
