Countdown to Saving My Homeworld: I Enter the Primordial Era

(Post-apocalyptic sci-fi + Fantasy) The protagonist is born in a future era of technological development, and, in his final year of high school, joins the Light-Tracing Ark transmigration project.

To save his home planet, Blue Star, he and his classmates use a time-travel machine to transmigrate at random to the end of the Primordial Era.

As the apocalypse draws near, people across the world transmigrate to an unknown era to learn different abilities, then return to Blue Star to fight the disaster.

In 2940, Blue Star's most advanced forecasting device, the Oracle, is unveiled.

According to the Oracle's predictions, Blue Star will begin entering its sixth mass-extinction event in 2950. Floods, earthquakes, and all manner of disasters will erupt one after another, and Blue Star will officially enter an era of mass extinction.

In 2985, after 85 years of painstaking research, scientists from more than 160 countries finally develop the Light-Tracing Ark, a machine capable of traveling through time and space.

To save their home planet and help humanity survive this mass-extinction era, more than 230 countries around the world hold an online conference and decide to launch the Homeworld Rescue Plan.

Anyone who meets the physical requirements will enter the Light-Tracing Ark and travel to different eras to study and train.

But the protagonist, Lu Ming, ends up in an unrecorded Primordial Era.
