In the Zhang Family of this era, he was a completely inconspicuous little shrimp among the monks.
As for why his surname was Li instead of Zhang, that was because his great-grandfather was a son-in-law who had married into the family.
Although he was still called Li Shenghong this time, probably because he traveled through time using a time capsule rather than traversing through the Time Devouring Space, the way in which he replaced his identity was clearly different.
In the past few instances, it was as if he had taken the place of the original owner. But this time, it felt as though he was experiencing the Awakening of Inherited Wisdom, and the energy was flowing back.
While the manifestations were similar, there was a slight difference innately.
By the way, it's worth mentioning that this side branch does not refer to Zijia's identity as part of the family's side branch, but that the entire Zhang Family of Yaoshan is considered a side branch.
