Global City Travel: I Exploded the Undead in the Safe House

"Daily Lottery + Lone Wolf + No Heroine + Safe House + Alien Western Fantasy + Summoning the Dead" Cities around the world have been cut apart by unknown forces and collectively thrown into another world. The power and network are cut off, and the countdown to the seven-day protection period begins. While everyone was still waiting for rescue, Xiao Jian had already walked out of the city, summoned the first skeleton, and built the first safe house in the region! While others lined up to grab water, he ate hot meals and took hot baths in the safe house. While others formed a team to surround and kill the monsters, he lay on the sofa and let the undead army farm monsters and carry supplies around the clock. While others fought for a piece of equipment, he extracted supplies from the earth every day, used monster source crystals to extract the top treasures in the current dimension, and there was a high-level mission lottery every seven days! Skeleton soldiers, skeleton warriors, skeleton archers, necromancers, mechanical skeletons, mutated bone beasts... As long as he gains experience, his undead can evolve infinitely along the technology tree! In this world, other people's talents can also be upgraded. Official strong men, hidden killers, alien races, none of them are stupid. But they need sleep, food, equipment, and loyalty. Xiao Jian's army is not needed. Many years later, when the allied forces of all ethnic groups came to the city, someone finally found out the true identity of the number one person in the anonymous safe house. "How many undead are hidden in that safe house?" Xiao Jian stood on the city wall and opened the space of the dead. The next second, the entire continent lit up with blue soul fire. "Correction." "This is not my safe house." "It's your graveyard."
