How Come I Merged with a Dog Demon, Half Human and Half Dog?

Qin Hua, who traveled to the Lingyun Realm, had these questions: First, after pretending to be an illegitimate child, he only wanted to go to the Qin Mansion to avoid becoming a slave. Unexpectedly, the day after arriving at the Qin Mansion, he only had three years left to live. Second, the lower world of the human world to which I belong does not have enough vitality. Besides, I have no spiritual roots. How can I cultivate immortality? Third, why did my body turn into a dog after merging with this dog demon? Could it be that he has been punished by God for his many evil deeds? !
