After top student Lu Yao dies suddenly, he is reborn in a post-apocalyptic wasteland.
When he faces a first-level threat, he activates the Metaverse System.
Using his mind, his main unit can make the virtual unit made up of neurons perform sign-ins in the Metaverse System, earning everything the main unit needs to grow stronger.
After modeling "Dad," the virtual unit rapidly manifests in the main unit, completing their fusion.
When his younger sister is in danger, Lu Yao knocks the spoiled young master Gao Qiu out of commission with a single punch.
When Gao Renmei, a sixth-rank intermediate martial artist, comes seeking revenge, the "Dad" model of young Lu Yao in the trial grounds crushes Gao Renmei's fourth-tier phantom beast with one punch.
The second beast attack, the third, the fourth... until the Nth...
Time and again, Lu Yao turns the tide and saves humanity from disaster.
