All Hail Cousin Brother - Chapter 39

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.

As an international mercenary, Feng Luo entered a technologically advanced parallel world during a mission.

After living several years in the new world, an online sci-fi game called War became popular across the entire Star Federation.

Desert Eagles, Barrett, AK-47, Apache, RPG… One after another, familiar gears awakened his memories of the past!

Terminator, Zerg, Resident Evil, the Force,… The missions that appeared after a system update made him even more suspicious and shocked! As such, Feng Luo entered War and became a sniper.

A modern-day antihero, who was infamous for his devious acts, dies in an explosion meant to take down a powerful criminal syndicate. Waking up in a world of sword and sorcery, he finds himself possessing a fragile, powerless body with a strange “System” that seems broken. Initially thinking he's doomed, he learns that by pretending to be weak, he can manipulate others into revealing their secrets, granting him abilities they possess. As he rises in power, he discovers that the System was intentionally sabotaged—by none other than his own future self.

Maid, older sister, younger sister, and even mother, all of them.
