When the End Comes, I Hand over My Immortal Father to the Country

In an accident, my father traveled to the world of immortality and became an immortal! Li Cheng didn't expect that Chengxian's father would activate the system and contact him through the system! Since then, resources for cultivating immortals have poured into Li Cheng, making Li Cheng the first cultivator of immortality on Blue Star! I thought I could continue practicing safely, but that day, the alien army came across the void, and the end of Blue Star came! Li Cheng knew that it was time to hand over the immortal father to the country!
