Uchiha Minamoto's solution to this was-
Strengthen the seal!
Uchiha Minamoto's [Lightning Light Chain Lock] could release five chains of lightning, but that was not its limit.
He had habitually released five chains before purely because his five fingers happened to have five chakra points...
In fact.
As long as Uchiha Minamoto wanted to, and his chakra reserves could sustain it.
His [Lightning Light Chain Lock] could release as many chains as he wanted!
Clink, clink-
With a series of crisp rattles.
Dozens of lightning chains extended from the [Lightning Light Chain Lock] Uchiha Minamoto had just released.
These lightning chains threaded through one another, intertwining until they formed an impenetrable net of lightning that directly "bagged" the still-struggling Black Zetsu.

Human shock appeared in Black Zetsu's inhuman eyes.
His dealings with Orochimaru were the most classified of secrets.
