Against the Clock: The Team Leader's Pursuit of Glory - Chapter 105 - We’re starting the Raid

Three thousand years of bowing down to the Demon Lord, I would rather be a mortal than a celestial being when looking back, but for her I will… become one who controls life and death!

Year 2056, in a city in the Yuan Jiang Su Jin area. On top of a ruined, shattered six story residential apartment sits a teenager wearing a combat vest, militaristic trousers, and alloyed battle boots. On his back is a hexagonal shield and equipped is a blood-shadow battle knife. He sits there silently on the edge of the roof. At this time, the sparkling sky was shining and there was a refreshing breath within the air that blew towards him. However, there was only silence within the ruined, deserted city, with an occasional howl that makes your heart skip a beat.
