My Father Is Zhang Jiao. Han, Prepare to Die

[A wild alternate-history take on the Three Kingdoms. Please bear with the differences from real history.]

A trip through a sewer sends Zhang Ning transmigrating to the end of the Eastern Han dynasty, where he becomes the son of Zhang Jue. He only wants to stay alive, but the commander who raised him to adulthood has stolen Yuan Shao's wife, Zhen Mi, and given her to him. At this critical moment, the System he has been begging for finally arrives after three days.

Beep! For plundering the wife of the Yuan family, bringing disgrace upon the household of Yuan Shao, a descendant of four generations of Three Excellencies, you receive a Grade C reward: one beginner Thunder Talisman.

Beep! With the first signs of you helping the Yellow Turban cause flourish, you receive a Grade D reward: the Host's body is now quantified. From now on, killing enemies grants experience points, so even going on a killing spree later is no longer a dream!

With the Thunder Talisman in hand, the world is mine.

I am Zhang Jue's son. Han dynasty, prepare to die!
