That's a hard one since it's a rare case where viewers only found out about him in the finale after Wei Wu Xian comes to realization remembering all the details including the spirit summoning done by the og body and feeling like he'll just be another Jin Guang Yao.
Maybe:
Not quite the same, since it's more about power before intelligent while for the character you mentioned it's about manipulating others to avenge his family member but that character can't do martial arts and don't plan to learn it:
I Am Nobody (Zhang Chu Lan) - saving energy mode on most of the time
Secrets of the Shadow Sect (FL) - has hidden power
The Immortal Ascension (Han Li ) - has many hidden treasured that could leveled him up/makes him win over people above his level
As for manipulating hmm:
Flourished Peony (Jiang Chang Yang)
Marry My Husband (SFL/main villain)
Mouse (ML)
