Traveling Through the Apocalypse: Starting the Underground Railroad

Liu Bi, who died suddenly, traveled to the world of mutated creatures in the apocalypse. The good news is that he traveled to the underground railway. The bad news is that although this underground railway is safer than the land, it is also full of dangers. Spore beasts, aberrations, mutated monsters, all crises are coming. Liu Bi will be there soon. When he could no longer hold on, a dilapidated underground settlement appeared in front of him. The ruined settlement gave Liu Bisheng hope. Just when Liu Bi settled down, there was a ding sound, and a window popped up in front of Liu Bi: "Countdown to attack time of mutated creatures: 336 hours."
