The bells in Jiang Qingyun's hand were called the Mother-Child Soul-suppressing Bells.
Once the bells rang, they could suppress souls and seize spirits, causing extreme pain to the wearer.
Among them, the mother and child bells function as master and servant. When the Mother Bell is worn by someone, it doesn't ring normally. As long as the holder of the Child Bell stimulates it to ring with their spiritual power, the Mother Bell will also make a sound, causing unbearable pain to the wearer, thereby achieving a controlling effect.
When the child cries, the mother gets a headache, which is fitting for the name of the Mother-Child Soul-suppressing Bells.
Of course, this magical weapon also has its drawbacks; otherwise, Jiang Qingyun would have used it from the beginning.
Each time the bells are used, they damage the wearer's soul.
Moreover, the cost of each use is significant.
After three uses at most, the wearer will become an idiot.
