Liu chengfeng was still unconscious, but it didn't affect Xia ruofei from feeling the heaven - defying function of the soul seal.
The moment the mother - child seal formed a connection, Xia ruofei knew that he could destroy Liu chengfeng's soul with a single thought.
And according to the description of the soul seal, no matter how far the two were, this soul restraint would not be affected.
What was even more terrifying was that even if Liu chengfeng's cultivation increased in the future, even if he had heaven - defying luck and his cultivation even surpassed Xia ruofei 's, he would not be able to get rid of the control of the soul seal. With the growth of cultivation and time, the connection between the child seal and Liu chengfeng's sea of consciousness would become closer and closer. In the end, they would basically become one.
