I have an Apocalypse City - Chapter 21 - : Supermarket Membership

Chen Lun traveled to the year before the game’s public beta and became an NPC in the game world.

And so, a new version was born…

Steampunk, spooky things, churches, shelters, the sequence paths of the seven righteous gods…

He put on his black top hat and stood on top of the ruins.

Standing behind him are the villain bosses of various versions in the previous life, the dead nun Floyd, the bloody painter Noah, the sword fighter Antonio, the delusional clown Alex…

Chen Lun: “Player spawns monsters, I spawn players, this is in the Taihe River…”

…

Also known as “Rational Use of This Sustainable Resource Named Players”, “These BOSS are really strong but they are all my younger brothers”, “No way! So I can also become a god? ! “

While on a school field trip in the Czech Republic, Kang Hyuk happens to stumble into a shop called “Archmage.” To his disbelief, the shop is actually owned by an archmage… from another world! Forced to become the Archmage’s disciple, Kang Hyuk is punted into the Kallian Continent, where might and magic overwhelm and wyverns fly high in the sky…

In this world, people are either sword-wielding knights, magic-wielding mages, or spirit-wielding summoners. There hasn’t been anyone yet who can do all three… until now.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?
