Apocalyptic God-Level Refuge

Nuclear wastewater infection breaks out, huge meteorites fall, and the world is about to enter an era of catastrophe! There are only twenty days left before the end! "Fortunately, I have a god-level shelter system!" Ye Feng opened the system upgrade interface with his backhand, and decisively completed a small goal first, fifty high-particle laser turrets! Kindness? You said that the nuclear wastewater infection situation has escalated in an all-round way, and the mutants are besieging the city and it is about to fall? Okay, look at the full output of my high-particle laser cannon! A base surrounds your entire mutant swarm, and I ask you if you are afraid! What? There are extraterrestrial creatures hidden in meteorites, and 70% of global shelters have been breached? OK! Look at my shelter being fully upgraded and reinforced! Iron door→Mezzanine door→Alloy door→Light particle laser channel! Anyway, I just like to see you trying to bite me but not being able to bite me, eh, just for fun!
