The original owner's talent was very poor, so bad that it could not be described. If not for that, she would not have not even stepped into the external refining stage after more than twenty years.
After all, in this great world where the spiritual energy of heaven and earth was dense and the cultivation techniques of the human race were widely available, as long as one's aptitude was similar, one could basically step into the external refinement stage.
Before the original owner became the Lin family's live-in son-in-law, he might not have been able to enter the external refining stage due to lack of resources. However, after he became the Lin family's live-in son-in-law, the Lin family still provided him with some basic resources.
Under such circumstances, the original owner had yet to enter the external refining stage. It could be seen that his talent was poor.
