Five years ago, Jason Stone was diagnosed with a terminal illness, and his girlfriend ran off with all his money. When he was about to commit suicide, his master, who was passing by Earth, took him to cultivate immortality. A thousand years later, he became a Great Sage, living on an alien world. One day, he finally connected to a spacetime vortex back to Earth, so he risked his life and made it back.

In the previous life, Evelyn Lester found that her roommate, Felice James, had planted malware on her phone and stolen her money. In the end, Evelyn was pushed off the roof by Felice and died. After Evelyn came back to the first day of college, Felice suggested traveling abroad again. This time, Evelyn put her smartphone in the dorm and took an ancient phone instead. She couldn't wait to see what Felice would do when she couldn't pretend to be wealthy again.

The alien bugs invaded, and humanity retreated to the "Ark" mobile fortress. Four years ago, hero Kevin piloted the mech "Silver Scar" to defeat the swarm, but retired after his entire squad fell. When the bugs returned, Kevin reapplied—only to show 0% compatibility. Spy Marshal Sam framed him for treason, sentenced him to death, and sent his mech to the scrapyard. As the swarm breached the gates and Kevin faced execution, "Silver Scar" self-activated, rescued him, and synced at 100%. Kevin repelled the swarm, and the whole city witnessed the war god's return.
