Actually, the weakness was very simple. On the night of the full moon every month, the forbidden technique Jiang Yi cultivated would backlash and let him have a taste of the evil deeds he had committed over the years.
Every time this happened, not only would he become an ordinary person, but his body would also suffer unimaginable pain. His entire body would feel like it was burning. Even a child could easily take his life.
However, Qin Xi was not that optimistic, because there was still a strangulation array preventing her from leaving.
Jiang Yi was not a fool. The Strangulation Array was an ancient array formation. Apart from him, there was probably no one else in this world who knew how to deactivate it. She guessed that Jiang Yi could stay safe all these years probably because of the Strangulation Array.
If that was the case, it would be troublesome.
She had no solution to the Strangulation Array. This made Qin Xi frustrated.
