Lu Yan has a simple creed in life: all monsters deserve to die. **
After traveling to a parallel world, he waited for twenty years and finally activated the [Monster Illustrated System] - as long as he kills monsters, he can extract abilities.
The problem is that this system is poisonous:
"Congratulations on getting the [Power of Jack] - Note: It is recommended to go to the construction site to move bricks."
"Achievement [Slay Hundreds of Monsters] Unlocked - Special Effect: Low-level monsters will run away when they see you (saving time and effort)."
** Bureau 749 has a headache: How to control this embryo-killer? **
Official slogan: "We shelter, we imprison."
Lu Yan added: "I am responsible for sending them to see the King of Hell."
**Qiu Xiaoyu has a dangerous hobby: studying Lu Yan's brain. **
As the chief researcher of the bureau, she insisted that "every monster has scientific research value" - until the experimental subject was "accidentally killed" by Lu Yan for the 108th time.
