Invasion of the Dark Abyss

The fusion of steam and elemental power, the fusion of aura and mecha, this is a world full of mystery and unknowns. The abyss invades and demons dance wildly. Lu Xiaoqi woke up and saw only darkness and remembered nothing. The only thing he can rely on is a diary that will unlock a diary entry at dawn, allowing him to regain his memory, and... An energy cannon that can bomb the entire map. So, when the evil god came... A hundred miles away from the battle between man and demon, in the inconspicuous grass, a pair of indifferent eyes stared closely at the battlefield. "It has been detected that there is a target with residual health on the battlefield. The system has locked the target. Do you want to fire?" "Boom——" Hundreds of miles away. "You have been slayed!" Demon: WTF?
