Among the newly married wives and concubines was a woman named Shen Youqing, who had only Second Grade aptitude. She had been eligible to become Han Li's Dao companion, but Han Li had recently raised the standards so only those with First Grade aptitude or a special physique could become his wife; Shen Youqing just missed the timing, arriving a little too late.
However, after learning about Shen Youqing's circumstances, Han Li changed his mind, mainly because he discovered a minor causal entanglement between them.
Upon divining further, he saw images of Shen Youqing and her childhood sweetheart Yan Nanxiao, with Yan Nanxiao obtaining a core shard of the Jade Talisman of Creation and other scenes where Yan Nanxiao was killed by the White Emperor who then stole the Immortal Treasure.
Influenced by this factor, Han Li generously changed his mind and ultimately took Shen Youqing as his wife.
