Transmigrating from the Apocalypse to a technologically developed, peaceful world, Qiu Yu’s killing skills cultivated through hundreds of life-and-death situations suddenly lost their use, and even his body turned into a weak, squeamish…

Qiu Yu’s world views shattered into pieces: What the heck is an Omega?!

Qiu Yu, who knows nothing but fighting, eventually decided to become an anchor for a full-dive game—not only could he use his battle techniques to make a living, but he also didn’t have to brave leaving the house and meeting people—it was the perfect job.

However, in his first-ever broadcast, he shot an arrow straight through the heart of the e-sport circle’s verified no.1 god of war.

Mu Feibai touched the place above his heart, the corner of his mouth hooking up: Interesting… Come play professionally.

Qiu Yu rejected him: social anxiety, not going, see ya.

…And then he was sold off by his live-streaming platform to play for a professional team.

Qiu Yu: This was different from my plan!

Mu Feibai: You shot an arrow straight into my heart… baby, you still want to run?
