The End of the World: Summon a Mobile Fortress as a Base

[Rebirth + Superpower + Doomsday + Natural Disaster + Demon + Fortress Upgrade + Hoarding of Supplies + Not the Holy Mother] The end of the world is coming, all kinds of extreme weather, demons are rampant, there are demon believers, traitors and rebels inside, and an army of demons is rampant outside, and the social order of Blue Star has collapsed. Yang Fan could only watch helplessly as his small fortress city of more than 50,000 people was breached by demons, and was reborn on the day when the doomsday came. The protagonist awakens the super fortress ability in advance, relies on the experience before rebirth, blocks doors and spawns monsters in advance, builds his own super fortress, looks for teammates in his previous life, and builds a satellite city. While others were dying of hunger, Yang Fan was enjoying himself in the Super Fortress, eating fresh meals, watching movies and playing games with his teammates. When others are besieged by demons and run for their lives, complete the upgraded super fortress and easily sweep away the demon army with one shot. When the army was defeated by the super-large Gate of Hell, Yang Fan drove the mobile fortress into the Gate of Hell, eliminated the demon kings and demons with a few shots, and closed the Gate of Hell before leaving.
