{Lin Fu}, a former network security engineer, transformed into a destitute scholar from the Yan Dynasty. As soon as he woke up, his selfish uncle and aunt robbed him of all his family property, and he awakened to the "destiny deduction simulator"! Simulate "suffering" and being starved to death, choose "anti-kill and collect evidence" to regain the ancestral home; deduce three questions before the imperial examination, and counterattack to become a successful scholar from the failed scholar; when challenged by a bully, simulate 10 battle plans, use hacker logic to dismantle moves, and defeat them with one punch; practice the residual skills passed down from the ancestors, and deduce the mental method to complete the battle god. Envoys of powerful ministers tripped up, and enemy countries invaded? He relied on the simulator to gain the upper hand and fought his way from a poor scholar to a god of war to protect the country. Even the emperor had to shout "Sir, please stay"!
