Five years ago, the God of War Zhao Feng disappeared during the doomsday battle and was declared a martyr. Five years later, he broke open the door of the underground laboratory with his bare hands and fled back to his hometown. The former homeland has been controlled by the dictator Chen Guodong. The betrayers have joined forces with alien forces, and the people groan under the iron heel. The old army has taken up the banner of resistance, and the genius opponent is driving the latest mecha. The fiancée who cried heartbrokenly for him back then is already standing beside the enemy. Zhao Feng had only one thought: Anyone who owes me must pay it back. Driving a tattered modified mecha with a Ares chip plug-in, Zhao Feng crushed the enemy's ace troops along the way. Chen Guodong never dreamed that the monster he created would be the first to demolish his command tower. The mecha roars and Iron Blood returns - Zhao Feng wants to let this apocalypse know that the God of War is not dead, but he just hasn't had enough fun yet.
