System Wants me to be a Villain? Dream on!

Imagine being reincarnated in a magical world and the system is hell bent on it taking away the first good thing you have, your family.
But what if you discovered a way to exploit the sytem tasks for your own benefits.

Wang Lu reincarnated in a strange new world discovers that he has system bent on messing his life up by turning him into a Villian From the get go.

The first mission given to him is to slaughter his entire clan and activate a new function.

Upon setting his eyes on the first mission, he almost cursed the system out loud. Did the system not know the Wang clan was among the Strongest clans in this world? This was clearly a pit.

"Villains die young and naive! I'm such a good person. how could I do something heinous!"

A few years later:

Wang Lu: "Senior sister!"
Red Moon Demoness Cai Yue: "No! Call me Wife!"
Shameless Wang Lu: " Wife! How about adding some seals on this Pagoda for me! I don't ask for much, just let it have the ability to seal cultivators and Devils alike! And it's best if can disintegrate their cultivation slowly without killing them. After all I'm trying to be a good person here!"

System: ??? ... You? A good person?
