Prologue

  Location: A certain city in southern China

  Time: 2016

  In the ruined city, the sound of gunfire and explosions was incessant, accompanied by the howls of various creatures. The air was thick with the stench of blood that made one's stomach churn!

  A group of armed personnel wearing uniform black combat suits are advancing towards the central area of this city, attacking with various light and heavy firearms. At the same time, a large number of multi-legged armed robots are continuously providing cover for these soldiers with powerful cannon fire.

  Midway, all sorts of monsters and demons kept rushing out from the ruins of various buildings to try to block their attack. However, the outcome was always being ruthlessly torn apart by various weapons and blown to pieces.

  In a skyscraper not far from the most intense battle area, a young man wearing sunglasses and a black leather trench coat stood expressionless at the top, staring at the area where the fierce battle was taking place.

  "Report, the remaining demonic forces have been suppressed in the central garden district. Other areas have been occupied by our troops. Each squad is thoroughly sweeping the occupied area for remaining enemies." A young woman wearing a black uniform approached the man and gave a standard military salute before reporting to him very briefly.

  The young man's head didn't even turn, his tone was flat as he issued a new command: "An Xi, notify the firepower support battalion to immediately start a full-scale fire saturation attack. After the attack, have the fifth squadron end the battle as soon as possible. Also, inform Major, she must pay attention to the situation on the outskirts of the city at all times. Once enemy reinforcements are discovered, immediately launch particle cannon attacks."

  "Yes!" A young woman named An Qi in a black uniform replied firmly and quickly turned around to spread this latest order.

  All that can be seen is the rooftop of the skyscraper behind her, which has been occupied by various military communication equipment and personnel. The latest order will soon be transmitted to each unit through this temporary command center.

  About five minutes later, a group of various models of armed helicopters whizzed by the side of the skyscraper and flew quickly towards the area not far away where fierce battles were taking place, pouring all their firepower into it, instantly turning the attacked area into a hell of fire and dust.

  After a barrage of artillery fire, ground troops launched their final assault on the area that had just been bombed.

  Looking ahead at the area that was in fierce battle, the young man's thoughts involuntarily went back to five years ago, that afternoon which changed his life.
