MC was at no point during the entire novel, in any danger. The apocalypse was never a major concern for him. The MC had no character growth and there was little to no personal connections made. The MC could have easily brought friends into his shelter during the start of the apocalypse, but ultimately decided against doing so. No real reason was ever given despite knowing how dangerous the outside world was for other people. Even at the very end when the entire universe is in danger, the MC only saves himself and his ship. While it is not mentioned because the novel came to a VERY abrupt conclusion, Earth was most certainly destroyed with all human life being wiped out. My biggest issue is that the MC kept having tasks issued to him by the system and the tasks would be completed within 1-2 chapters. He was essentially a Task monkey.
