He was born into a good family and Jiang Laoda is busy in the year but can’t eat a full meal. Two younger brothers can marry a wife, but he is starved to death… Jiang Zhen feels unbearable.

Don’t want to feed me? OK, I kill the chicken myself.

Don’t you give me a glimpse of food? It doesn’t matter, the door of the granary will be opened as soon as it goes down.

Want to tell me that I am not filial? Ok, I immediately took the knife into the county to slash people, and let the county grandfather grab all of us.

- Description from Novelupdates

Eren Idril died as an old, decrepit, and piss-poor adventurer by the maws of a D-Rank monster. He had a lot of unfulfilled dreams and desires that couldn't see the light of the day after the light in his own eyes died down.

But fortunately for him and unfortunately for the world, that wasn't his end. Eren was somehow dived back in time when he was a mere teen, attending Lionheart Academy for adventurers.

When life gives him a second chance, Eren decides to exploit it to its fullest. Experience his vile deeds as he partakes in them without feeling the slightest bit of hesitation.

“Martial Arts World...” Death murmured, shocked by the turn of the events. How could he, primordial being of the afterlife, get tricked by a mere human? Not just a mere human, but also earthling, race that was weakest of the twenty realms. Death realized the extent of his mistake. An earthling had just jumped into the river of the reincarnation, where he definitely didn’t belong. It was too late. The damage has been done. The matter was now out of his hands. “Kiernan Hunter...” ... Remake of the Martial Arts System, and while the concept stays the same, the story is completely different. A few names, etc, stays the same, but mostly whole new story.
