Lord of Eternal Night: a Girl with Potential in the Starting Contract

After the sun set, it never rose again. This is a world shrouded in [Eternal Night]. Nightmares, undead, strange beasts, and demons return from the dead realm and invade the world. If you want to survive, you can only seek the protection of a powerful territory... Or become a [Lord] and personally build an indestructible territory. Bai Yan, who traveled through time, got a "Girl Development Manual", which allows him to contract and develop various potential girls and build a territory. An architect girl who can make [Arrow Tower], [Heavy Cannon], and [Alchemy Workshop]; A pharmacist girl who can brew [Life Potion], [Frenzy Potion], and [Iron Potion]; A maker girl who can make [Lightning Spear], [Giant Gloves], and [Regeneration Amulet]; There are even various powerful fighting girls who can destroy giant dragons with their bare hands and destroy heaven and earth with magic... As a result, Bai Yan began to embark on the path of territory construction through collection, contracting, cultivation, and management. A few years later, when the great Bai·Yan Yan, the city lord of Ideal City, the terminator of eternal night, and the sun walking on the earth, was asked why he wanted to retain his contract experience, he spoke righteously. "Listen to my excuses, I contracted them just because I like their strength!"
