Blackstone Code - Chapter 47:

I killed the protagonist.Yeah. He was a real son of a bitch.Noah didn’t just stumble into this mess. He walked straight in—grinning, sword in hand.One day, he wakes up inside his favorite game… as a throwaway side character no one remembers. A complete nobody. But when he figures out who the so-called “main character” is?Some smug, self-righteous psycho.So yeah—he killed him. No regrets.Story over, right?Not exactly.Because this world? It’s got one more player.“WHAT THE FUCK IS GOING ON!?”Now the story’s off the rails, the world’s gone completely off-script, and Noah’s got a new goal:Steal the hero’s spot. Rewrite the plot. Find out who the hell this other player is. And maybe—just maybe—make this damn story fun for once.

“You are mine, and I am yours…”

The world cannot be saved by the victory of a single man. This book begins at the point where the climax should occur; the battle between a Demon Queen who is a little strange and a Hero who is a little curious.

However, not only do these two give up the battle, instead, they join hands to directly challenge the complicated social structure which dictates that humans and demons must forever be in conflict.

This is too reckless right? How can this be done? Undoubtedly, you are thinking that.

Come, please turn the page. You are about to read a story that has never been told before; the story of the Hero… and the Demon Queen.

Ling Jingxuan can’t help but be speechless.This life, can this pit be any bigger?

There was no one who was not disappointed from the imperial family. But, don’t know when slave wife learned it but poison concubine’s poison was incomparable, who dares to try to straighten him out?

“What? 30 Wen? You’re robbing from people, so expensive!”

One day of the month of a certain year, Ling Jingxuan takes the two little buns to the market to buy living necessities.These five year old little buns after hearing the price have to hold back their red faces. Fried little hands rigidly held onto the broken wallet, Ling Jingxuan suddenly wanted to cry but had no tears. Sons, we earned money but not spending it, don’t tell me its left for the foals?

At the end, it was obvious they carried two liang of silver. Stuff that was sold at the last minute were the cheapest. Seeing the smile of satisfaction from the little fried buns, Ling Jingxuan secretly vowed. One day he would develop them into super meat buns，a rich 2nd generation family!
