王继恩 / Wang Jien
Wang Jien / 王继恩 is the palace eunuch whose actions shape the succession sequence in 170.宋太祖之死：烛影斧声，阴谋论中的人性谜团（下）. After 赵匡胤 / 宋太祖 dies, 宋皇后 reportedly tells him to summon 赵德芳.
The episode says Wang Jien instead goes to 赵光义 / 宋太宗 at the Kaifeng office, where he also encounters 程德玄. Wang then urges Zhao Guangyi to move quickly, warning that delay could let the throne fall to someone else.
For the source, Wang Jien is a small actor with large institutional meaning. His route turns a palace instruction into a completed succession path, making the process look organized before open recognition catches up.
