Lu Xun was beheading demons and exterminating evil, not knowing what a worthy opponent was.

The young demoness was a 400-year-old golden snake, cold as ice, and arrogant. The powerful female demon was a thousand-year-old white snake, mature and charming, with captivating beauty. The little female demon was a 200-year-old fox, mischievous and adorable, full of liveliness.“Something’s not right!”“These female demons are not normal!”However, Lu Xun gradually discovered that not only were these female demons suspicious, but there were even more peculiar things happening outside!
