Awakening The Weakest Talent: Only I Level Up - Chapter 21

Synopsis is in the beginning first chapter, so you can try to read it first.Zhang Fei is an ordinary human, but he is also an Incubus, and he also a Heavenly Fox.

Some say he is the bad apple in a basket, that he’s rotting everything around him with disgrace and corruption.

Some say he is the biggest scum of the South Zhanbu Continent, that he’s colluding with the dark sects to cheat, steal, and commit all manner of atrocities.

Some say he is the most wanted playboy. “Lock your daughters at home to keep Fang Xing away!”

To all of those people, “That’s right, I am that big rotten apple. Any problem with that?”

This brand of anti-hero is a young orphan with poor prospects and nothing more than the keepsakes of his uncles. He plots, schemes, and orchestrates all manner of villainy in his quest for power and revenge, unafraid to live precariously and make enemies out of those he really should not.

A spin-off of Lillia and Treize, Meg and Seron is a high school adventure/mystery/romance/comedy of sorts taking place in the rough equivalent of the 1950s. The story follows Seron, a stoic and handsome bookworm who is in love with his classmate–a sweet, oblivious transfer student named Meg.

Meg and Seron takes place at around the same time as Lillia and Treize, but knowledge of the main series is not necessary to read Meg and Seron.
