This was because Zhao Xin's Cultivation was progressing far more quickly than Xu Lei's had at her age.
Xu Lei had already been twenty-one years old when he reached the Lotus Embryo Realm!
Of course, Xu Lei harbored no ill will. To be more precise, it was envy.
After arriving at their destination, Xu Lei and Zhao Xin investigated again and confirmed that their target was indeed a Spirit Monster.
However, they still couldn't determine what kind of Spirit Monster it was.
All they knew was that yesterday, for some unknown reason, it had gone on a rampage and drained several people of their blood.
It had likely disposed of the bodies as well.
As a result, those people were now officially considered missing.
The Spirit Monster was currently disguised as a young man, having become the live-in son-in-law of a wealthy Landlord.
He was in charge of a slaughterhouse and a tavern under the Landlord's name.
Xu Lei figured this was for the convenience of drinking blood.
