Shi Xiaotian's Systematic Life

The death of her parents and the unkindness of her relatives forced her to go to a dead end. The contract with her boss expired on the day she turned twenty. She was so happy that she unexpectedly died unexpectedly during her last mission. The Purple Jade Buddha gave her the opportunity to be reborn. When she was reborn at the age of 6, she was struck by a purple thunderbolt from the sky just after she woke up. From then on, her life changed dramatically. She learned the skills of a doctor, accepted tasks, and received rewards. She can upgrade, she can kill people and destroy equipment, she is immortal, she is amazing. After rebirth, how will she reach the top with the help of the heaven-defying system? Encountering many obstacles on the road, one word, kill! Kill! Kill!
