In the 847th year of the Great Yu Calendar, Su Yuxing transmigrated and became a small jailer of the imperial prison in Great Yu Dynasty.

"Guarding the Demon Sect’s ancestor for 30 years. Reward: [Devilish Toad Heaven-Swallowing Technique], 3,000 years of martial arts cultivation!”

"You have guarded the Great Demon Saint for 50 years. Divine power-Heavenly Transformation!"

"Guarding the Holy Maiden of the Compassion Sect for 70 years. Reward: Full of descendants!"
