Review Detail of Shad in When Doomsday Comes, I Can Upgrade My Refuge Infinitely

The story was good at the start but when thw upgrade of drone to have AI resulted in tranaforming the drone to iron man. It got stupid not only that various mc and dc characters emerge from transforming luxury cars that wasnt even there to begin with there not even machines anymore. Its not even worth it anymore this author also made some novels that has great idea but poor story
