I Became a Warlord in World War I: Starting at Verdun

Machine guns reap lives, and artillery levels the land. Yet this is also an undeveloped trove of treasures, provided Wu Lin can survive in the muddy trenches. Then another accident occurred. The box of Pandora was opened. The gates of hell appeared in the real world. Twisted creations of war appeared at the edge of the battlefield. An unbearable stench hung in the air, driving people to the brink of mental collapse. Across the ruined land, tanks that should have been sent into battle were replaced by a horde of mindless war machines. Only then did Wu Lin keenly realize that humans were not the only beings in this world. There were also nightmares from hell.
