Chu Yuqin is just a clone created by Chu Yunzhi.
Although she also possesses the memories of the Ancestor of the Strange, she is still somewhat different from the Ancestor of the Strange.
Under normal circumstances, the Ancestor of the Strange would not actively seal other mysterious beings, but Chu Yuqin being able to release such pure Mysterious Power indicates that her memory has already recovered.
In the case of her memory recovery, yet still sealing mysteries, it proves she stands on the side of humans.
Could it be that Chu Yuqin has developed feelings for Lu Chen? So she helped Lu Chen seal the Deceit Tide?
If that's the case, then it's troublesome.
If Chu Yuqin, as an ancestor's clone, were to side with Lu Chen, it would make it even easier for Lu Chen to seize the Memory Pearls of other Ancestors of the Strange in the future.
