[Travel + hegemony + zombies + heroine + infrastructure + violent soldiers]
In his previous life, Qian Duoduo was the founding emperor of the Chuxin Empire. After his death, he was reincarnated into the modern world. A zombie virus accidentally broke out in this world. Qian Duoduo activated the city-state system. Killing zombies can earn system points, which can be used to summon soldiers to exchange for items.
While others were still afraid of zombies, Qian Duoduo had already led the army to clean up the zombies.
While others are still paying for a biscuit, the food grown in the spiritual fields in the city with a lot of money is already too much to eat.
While others were still feeling proud about awakening their abilities, Qian Duoduo's army had already begun upgrading their abilities on a large scale.
