Changes in the World: I Killed 10,000 Rats at the Beginning

"The host asks you to actively complete the system binding task, kill 10,000 mutant rats, and collect 10,000 justice points to complete the binding. There are still five days left to complete the deadline, otherwise you will be erased..." "The deadline is four days..." "Three days..." "Two days..." "Your sister, you will be erased if you don't complete this system..." "Then tell me where the mice are hiding, or they will be wiped out together! It's not like I haven't died before!" Long Feiyu said to the system nonchalantly. "Your uncle, take Nancheng out of the city..." Under the guidance of the system, Long Feiyu finally killed 10,000 mice and collected 10,000 justice points, completing the system binding task! "Congratulations to the host, for collecting 10,000 points of justice, completing the system binding task, and being rewarded with a copy of the Mind Technique, and a random auxiliary spirit beast... From then on, Long Feiyu started a new life. He had nothing to do but kill strange beasts and level up. Otherwise, he would bask in the sun decadently and read novels, or go to school to play guitar and wait for the ladies to play with him. He was free and easy!
