Zombie Apocalypse! Summon Delta Operators at the Beginning!

[Doomsday zombies + Delta operation + system + savior + invincible flow] Ten years of cataclysm. The global population has dropped by 90%, and the remaining survivors are lingering in the ruins. Li Feng, an ordinary player who died suddenly while playing Operation Delta all night long. When he opened his eyes again, he was already standing in the doomsday wasteland, holding a system in his hand! The map of the space base that he was most familiar with during his lifetime became his sanctuary. Ordinary zombies, aberrations, tyrants, half-zombie men! This world is a hundred times crueler than the game! Food is contaminated, water sources are eroded, and the living are more terrifying than the dead. Cannibal gangs use people as food rations, women and children are clearly priced on the black market, and survivors linger in the ruins like wild dogs. The world has been dead for ten years. Li Feng is here, and he wants to turn the world over again!
