Demonic Martial Turmoil: I Awaken the Martial Limit-Break System

[Non-naive MC + Transmigration + System + Martial Limit-Break + Decisive Killing] Zhou Yan died suddenly after staying up all night playing games, and opened his eyes to become the lowest-class peasant in the Great Xia Dynasty. His father doesn't dote on him, his mother doesn't love him, he's the third child, farming and chopping wood daily, his watery porridge reflecting his own miserable face. This world is overrun by demon beasts, and martial artists reign supreme. Want a good life? Fine, practice martial arts. Want to stand out? Fine, practice martial arts. Want to survive? Sorry, you still have to practice martial arts. Starting from the martial foundation, he awakened the `[Martial Limit-Break System]`! What martial arts bottleneck? What realm shackles? Before the Limit-Break System, they're all scrap paper. Kill demon beasts to gain proficiency, and break through martial limits! From the third son of a farming family despised by everyone in Yangliu Village, to a peerless Martial Saint who tramples demon beasts and shatters the heavens with his fists- This chaotic world is about to change.
