They did not expect the high priest to think this way.
Tang Yue has a Heavenly Venomous Insect Body. Once she reached 20 years old and did not have the Heavenly Venomous Insect Divine Arts to cultivate, she would turn into the Vicious Gu King and harm the human world. Therefore, she had to end her life at 20 years old.
As the son-in-law of the priest, Feng Yun had the obligation to help Tang Yue find the Heavenly Venomous Insect Divine Arts.
However, the Heavenly Venomous Insect Divine Arts had disappeared for ten thousand years. To find it was simply heaven's talk.
The high priest had never thought that Feng Yun would be able to find the Heavenly Venomous Insect Divine Arts.
Therefore, he asked Feng Yun to return to Venomous Insect City so that he could die first. Then, when the female priest's life ended, they could go back to afterlife together again.
