Land Sword Fairy! Li Guoshi of the Tang Dynasty

The sword fairy Li Qinglian was reborn in the Tang Dynasty, but demons were everywhere and humanity was declining. Awaken the demon-slaying and demon-slaying system and kill all the demons that cause harm to the world! In this life, I am a fairy in the mortal world, and I will give my human race a clear future! PS: The introduction is weak. I guarantee that the protagonist is not the Holy Mother. He uses killing to stop war and kill to prove the truth. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
