With his mother and sisters in the car, Luan realized how they brought the car here: there was a rope tied to the front of the car. Luan with sensory perception knew that Ingrid had finished killing the beasts that were attacking humans and was bringing them towards him.
He still had time. He first went to Naga and with the knife made of a scorpion claw Luan started to dismantle the Naga using his Qi around the knife.
Luan mainly wanted the Naga's bones, as he would need enough strong bones to be able to create bone reconstruction pills, among some other pills to help his mother and sisters who had fractured and broken some bones.
