Review Detail of DarkAngel1005 in Apocalypse: My Technological City has Infinite Upgrades

The idea and grammar is great, I just wished its not so "fast paced" where the author literally skipped days and just noted diary entries yet no corresponding points were properly counted, also the MC was idle for that long??? how about upgrading the shelters defense? facilities? farming? energy? going out to gather resources? he already did it once with suite and guns and all but suddenly ot gets skipped? also shop has skills and all but MC is not even buying nor training on skills and other weapons? he is stuck up on guns, but cold weapons also have their pros and cons especially on close combat, then lastly he decided to upgrade his physic with warning of pain during assimilation but MC decided to do it outside and just hides near a so called big tree?? I dont know if the MC is dumb or the plot and idea of the author is a mess. its s promising story, just plan the development properly and make it sensible. maybe a revision of the first chapters?? Like, improve the gate, add drainage, auto defense, alternative powe source, waste management, upgrade greenhouse, upgrade the R&D and so many more...
