I Have Medicine - Chapter 484 - Swallowtail City

Jacob Steve, an Old Man, died at 116 after living a whole life.

But Jacob always had a dark side, which he always suppressed and hid from others.
However, in the later years of his life, when death was inevitable, he understood there wasn't any point in having wealth, knowledge, or desires if you couldn't have a life to enjoy them.

He became obsessed with fabled immortality and devoted his reaming life to extending his fleeting lifespan, but just like any other failed.

However, he mysteriously got another chance at life and found a way that led to fabled immortality.
But he was also forewarned that the way led to it was filled with blood and darkness!

In the end, Jacob chose it anyway with no way of going back, and it was also the start of his suffering and his icky, brutal journey toward the 'Immortality' he wanted so badly!

In the grand world of Nova, many different races exist such as elves, humans, dwarves and beastmen and through years of war, strife and competition the world has grown, becoming home to great empires and countries throughout the oceans and five continents. However, to the great creators the world has become stagnant and boring, ever since the calamity that was the Church of Light and their Holy White empire.

Now the Dark God has created a new race after years upon years of dedicated effort. A species that is like none other and his hope for Nova’s future….Dungeon cores, beings that have the ability to reshape the very world itself, entering the domain of the gods.

Join Frost a newly born first generation Dungeon core as he embarks upon his journey within Nova and carves out his place in the world. How will the world’s current denizens react to his birth? Will they be friends or foes? And most of all how the Light God react to this new addition to the world, will he accept them or seek to destroy them?

This novel incorporates dungeon building and management but most of that won’t fully take off until the later volumes when Frost has much more floors and money to play around with. This is not a solely dungeon story as the MC Frost will have to explore and interact with the world of Nova much like how an adventurer would and forewarning the story is slow. There’s a lot of details and avenues which the story goes into, not simply battles, wars and action, it follows all aspects of Frost’s life, his growth and interactions with Nova not only as a Dungeon core but also as a person.
