This book is dedicated to the Calamity journey, in an attempt to make up for the regret it left unfinished.
The story uses the setting of the old version of Terraria: Calamity Mod, and takes place in a vast, fully realized world. The plot unfolds gradually, so even readers who have never played the game can follow along.
While sorting through his missing father's room, Yang Cheng accidentally drinks a teleportation potion and transmigrates to the continent of Terraria, where he begins a new life.
At the System's direction, he awakens the sixth class, Alchemist, and becomes deeply bound to it, unable to gain the effects of any other class. Still, thanks to his solid understanding of the game and the boost provided by the game System, he thrives in this world.
The days pass slowly, and he thinks this peaceful life will go on forever. Then, out of nowhere, a tunnel leading to Hell appears.
The world is about to change beyond recognition, and Yang Cheng is forced to become its one and only savior, uncover the truth, and rescue a world on the brink of collapse.
