The end of the world has come, order has collapsed, and strange beasts are running rampant. When Lin Chuan woke up, there was only ruins left within a hundred miles. Good news: He's bound to a doomsday survival system. Bad news: The novice gift package sent by the system is an egg. When others awakened their thunder and fire powers, evolved their bone blades, and became saints in their bodies, Lin Chuan silently took out eggs one after another. Everyone laughed at him: "What's the use of eggs in the apocalypse?" Until that day, the third-order mutant giant lizard destroyed half of the safe zone, and the awakened people in the city fled in defeat. Lin Chuan stood on the ruins and cracked open the last gold-patterned egg - "I'll treat you to a whole-egg feast today." The giant lizard looked down at the egg that couldn't even fill the space between his toes, and was about to swallow it in one gulp, when the next second the whole street exploded into light. Later, a legend spread in the safe zone: Don't mess with the egg seller. He can exchange you for one egg, your life for two eggs, your vitality for three eggs... He will make you kneel down and call daddy.
