Lin Xuan travels through the end of Gaowu, where mankind is on the verge of extinction and survival is difficult. He accidentally got the "Many Children, Many Blessings" system, which allows him to bind his children to get rebates. Outside the shelter, he picked up three mythical beast cubs and successfully bound them. While others struggled for food, he swept across the wasteland with his cub who could transform into a mythical beast. During this period, he rescued the girl, became a enemy of the mercenary captain, and even used the crystal core of the mythical beast in exchange for martial arts to kill the enemy. The three cubs transformed into each other and called for daddy, and the Valkyrie came looking for her son. The Zerg from another world invades, the whole family fights against it, Zai Zai evolves, and the final chapter is explosive. Finally, he took Valkyrie and Zai Zai to a higher plane, unlocked new functions, opened the "Interstellar Dad" copy, and reached the top.
