My Cell Prison - Chapter 33 - Unexpected Visitor

Betrayed. Alone. Forced to survive the deadliest dungeon in the universe. As a Tulland dreamed of adventure. To be someone who sees every-place, goes every-where, and does every-thing. All he wanted was to go beyond the confines of his tiny island. So, when the Church denied him a class, he turned to the only other being that could grant him his wish; The System. And the System delivered. Tulland got Class, but not one he ever wished for. Awakening as a Farmer, he finds himself in the one place where he can grow away from the clutches of the Church — The Infinite; a dungeon whose end even heroes of old have never seen. Armed with what dregs of power the System deigned to give him, Tulland will have to figure out how to survive, and cultivate, the universe’s deadliest dungeon. Expect: + Progression fantasy with actual farming! + A very stubborn MC + Combat! Action! Plants!

We were a peaceful people living in harmony with nature in the vast lands of Lyréanor, but this peace was short-lived when our people were defeated by the dark elves, an ancient people even older than this world. It is said that they arrived in Lyréanor by boat and since their arrival, chaos has been unleashed. Proud of their obscure power, derived from dark rituals, they have raised gigantic armies of monsters whose name is synonymous with terror: ‘Obscurus’.They went on the rampage, and everywhere they went the grass didn't grow back, life died and disintegrated. Seven, there were seven. The seven dark elves known as the Lords of the Apocalypse. A single gesture from them was enough to strike us all down, a single gesture from one of them was enough to decimate us in blood and terror.And as I, Foster, contemplate the macabre scene before me, the bloodied and deformed bodies of my fellow elfes beings, and as death grips my soul, a strange sign appeared before me.[Ding...
