To pull someone from the past, one must first ensure that this individual no longer exists in the present, otherwise, the inevitable conflict between past and future would result in one of them disappearing. Moreover, time-space manipulation does not work on beings above an Innate Dao Sovereign.
An Innate Dao Sovereign, once proven, is proven for eternity. Whether it's the past or the future, they are in sync with the present. Thus, the moment the present self becomes an Innate Dao Sovereign, the past self transforms into an Innate Dao Sovereign at the same time.
This is the trinity, where past, present, and future are synchronized at this moment, and the weaker past self thus vanishes, naturally eliminating the possibility of being fished out of the River of Time and Space.
