Di Xiu transmigrated, becoming a gray rat in another world. Not only must he build a protective dungeon to safeguard himself and his race, but he must also constantly guard against invasions from other races. Humans, gods, demons, monsters, dragons, elves, ancient taboos... even outworld gods coveting the world! The former order crumbles, and the apocalypse topples the towers of civilization. In the face of life and death, Di Xiu comprehends the truth of magic. Magic is not chanting, but a rigorous set of underlying world protocols! Only with the correct logical framework can it be safely compiled and run. While other mages are still struggling to chant spells with their flesh and blood, Di Xiu is already debugging magic circuits in the dungeon, developing the third-generation gray rat exoskeleton armor, heavy armored mechs, and aerospace carriers... The magical industrial age has begun! The gray rats are building a jungle of steel and gears. Mechanical rats wield precision...

Until a game quietly arrived, this insurmountable gap began to crumble:

What? You can become stronger just by breathing, and level up by defeating monsters!

Lu Chuan: "What are you talking about? This is just an ordinary sandbox game."

Lin Qi, inexplicably transported to a fantasy world, unexpectedly became bound to the priceless Book of a Hundred Lifetimes. After death, his soul could remain constant, reincarnating into his own family lineage, inheriting his previous life's talents, physique, and possessions! As long as his bloodline continued, his life would endure!
