story starts as typical travel to past with a system in apocalypse novel, but with nerfs. then it continues as typical xianxia, just to change to some kind of mystery novel. authors is making lots of plotholes and then forcibly explains them later in story with twisted logic. for someone who is reincarnated into past MC is really stupid. instead of getting help, he tries to do everything solo... fate of the whole city hangs on his knowledge, but he must be in front lines every single time there is a disaster. what ticks me the off most is when there is ultra time sensitive danger MC has to write an essay to other characters explaining his logic for running away. also the philosophical discussions with enemies about class divide between superhumans and normals. it is just rinse and repeat. every time enemies get caught they have to justify their betrayal and every time reason is the same (with slight differences). and world background just doesnt make sense... whole city transmigrated to other planet, having zombie apocalypse, viruses abound, monsters attacking and in just 50 years they have population of tens of millions. even if city had 50 million people when it transmigrated i doubt that 1 in 100 could survive initial 10 years. food intake that even 1 million city needs everyday is enormous, not to mention bigger cities.
