The Legend of Mantis Cultivating Immortality

I, the praying mantis, am parasitized by iron worms at the beginning, and my life hangs by a thread! A thunderbolt awakened my ancient Leize bloodline! The iron worm has also become my most loyal fighting partner! I thought I could rely on my senior sister and stay safe in the sect! Who knew that the fate of the Song Dynasty was over, the sect was destroyed, and the whereabouts of the senior sister were unknown! When I was wandering, I was captured and made to refine elixirs. I didn't die, but instead made golden elixirs in the furnace. I was captured by a Yuanying boss and used as a battle pet. He was very kind to me and helped my Yuanying. I know that he just wants to get fat and eat me to become a god. I pretended to be ignorant, hid that I could speak, and hid the Razer in me. At the critical moment when he transformed into a god, I gave him the most painful stab in the back in his life. Falling into the void, I sacrificed my arms to reforge my double blades. When I was born again, I had transformed into a human form. I walked up to the senior sister who had been searching for me for hundreds of years and said softly: "Senior sister, don't you recognize the knife?"
