Mortal Nie Qiangwei has a living dead father.
It just so happens that this living dead person is still the former Demon Lord of the Demon Clan.
In order to save her father, she traveled through the secret passage in the library and came to the secret realm of the Immortal Cultivation Sect, the Void Sect.
Here, she met the immortal Yuan Xingye, and also obtained the water of Jiepo Spring.
After returning to the demon clan to rescue her father, she was surprised to find that this man was not her father, but the ancient god who sacrificed his life to seal the ancient demon king, and was also the father of Yuan Xingye.
The ancient god promised Nie Qiangwei that as long as Nie Qiangwei practiced diligently and experienced thunder tribulations to become a god and sealed the ancient demon's respect under the Demon-Suppressing Pagoda, he would help her retrieve her father's soul and marry Yuan Xingye to her.
Nie Qiangwei couldn't resist the temptation and formed a blood alliance with him. If she broke the oath, she would die an ugly death.
From then on, Nie Qiangwei, a mortal after the Immortal and Demon Lord, embarked on a path of cultivating immortality.
Purpose: In order for the notorious family to gain status in the Five Realms, Nie Qiangwei must choose to become a god rather than a demon.
