The Phantom (Illusion) Clan was persecuted in the cultivation world, so they had no choice but to transmigrate to an interstellar world. There, they discovered they could no longer have children, so they transmigrated to Earth. After a long time, they managed to have just one child. With no other choice, they had to search once again for a suitable world, break through the spatial barriers, and transmigrate there, hoping to grow their clan and keep it from going extinct.
Xuan Lingxuan was the only child born to the Phantom Clan after they expended an enormous amount of energy. It took him a thousand years just to reach adulthood. But, unexpectedly, one day, three months before he came of age, he accidentally stumbled into the formation his grandfather had made to break through the spatial barriers, and transmigrated along with him.
To his dismay, his grandfather had lost a great deal of energy and suffered severe injuries protecting him from the spatial storm. He could only recuperate inside the System of the auxiliary game Xuan Lingxuan played.
Most importantly, Xuan Lingxuan couldn't leave the little world he had opened up. It was enough to make him frantic.
Xuan Lingxuan was the precious darling of his clan, treasured so dearly that they feared he might break if held too tightly or melt if kept in their mouths. In this unfamiliar world, they had no idea whether he would adapt. Fortunately, they had thrown him into the army for training beforehand, which let them worry just a little less.
In short, this is the story of a willful idiot having babies for no apparent reason in another world.
