A fellow Taoist said before that the writing was too unstable, and that the protagonist could have simply abandoned the clone and left. If you think about it carefully, it is indeed true. After all, Ding Yuan is trapped and cannot get out. Even if he could get out, he would not let the protagonist enter the secret realm so easily.
