Witcher: I Can Extract Everything - Chapter 72 - Conflict

In the game Myth2, Klaus Park was already considered a top player at just 13 years old. With his advanced knowledge of the game and methods of adapting to the most varied situations, he became a world champion younger than anyone else. However, due to a tragic incident, he left his team and the gaming world a year later.

Now, 7 years after leaving the professional scene, he returned to play the eminent VRMMORPG called Rise Online, a unique game of unrestricted freedom whose number of players already exceeds one hundred million. This game allows players to use real-world skills such as martial arts, archery, blacksmithing, or reaction time for their own benefit, along with the freedom to explore 7 colossal, mythological worlds.

Planning how to conquer dungeons? Fight against powerful guilds? Slay the Werewolf King? Face hordes of thousands of zombies? Have the power to revive the dead? Or discover unknown battle techniques?

None of this is impossible for Klaus, a legendary player, and holder of the Psych Class, allowing him to see and talk to spirits, copy abilities, cast magic items, and see the signs that no one else can see across the worlds. His real goal is to reach the throne of the paranormal world and the top of the player and guild ranks of Rise Online. No matter what is in front of him, he will be head-on with his best, be it the High Lord of Vampires or the strongest Guild Master.

Kieran was just an ordinary part-timer — a high school dropout who had also given up on boxing. With no parents and no real family, he survived by working his ass off every day. He was raised by a man he believed to be his father, but later discovered he wasn't — though the man passed away before the truth could fully sink in. What Kieran didn’t know was that he was actually the sole heir to a powerful business empire, the hidden son of a wealthy tycoon.

She, a modern hidden ghost leader of an organization which gathered insane prodigies proficient in the various differing skill-sets. Highly skilled in medicine and poison, executes covert assassinations, viewed as insane and demonic in the eyes of people of the world. Killed in an accident, and reborn into the body of a disfigured young girl.

What? Face disfigured, identity stolen? A return to the family dim and hopeless? Her identity can be given up, her family can be forgone, but as for the one who harmed her predecessor who inhabited this same body, if she didn’t at least make them scream in unimaginable agony and throw them into a state of wretchedness, how could she live up to her demonic reputation? Endless turmoil ensues and it’s a battle to dominate over all! See how she shook the world dressed in a suit of red, her sword up against the dominant powers that rocked the Heavens! Her name spread across the seas, shocking the earth!
