Apocalypse Troop-Building System

Red Alert Protagonist Disguised as Government Forces

Mass-Producing Troops With No Resource Cost and Unlimited Numbers, So Over-the-Top It’s Fun

I once read a story where the protagonist's System could analyze living creatures by seeing and touching them. Afterward, he could summon troops without limit and farm items endlessly, transmigrating across different worlds. In Jurassic World, he analyzed a Tyrannosaurus rex, and the summoned creatures filled a radius of over a thousand meters. I cannot find it anymore. Please help.

Infrastructure, Building Power, Mass Troop Recruitment

Any recommendations for novels about infrastructure building, growing a faction, and rapidly expanding the army? Thanks!
