God-Defying Madman System

I am Lin Bengtian, and I have a mission system! Zhao Ritian and Long Aotian are both scumbags in front of me. What, peeking at a beautiful woman taking a shower counts as completing the mission? The mission reward is a super elixir, which helps me reach the peak of my power! What, does conquering the evil Loli princess count as completing the mission? The mission rewards changed my physique, making me devour the world and become so awesome! Lin Bengtian: Come out, Doraemon, and give me more mission rewards! The rabbit with a black face: I am a system elf, not a Doraemon. Go and do tasks for me!
