Pickled Mustard and Gruel, Goblin Adds Yellow Robe to Me

Xiao Yi traveled through time and became the succubus supervisor at the bottom of the demon mine. He only had a group of skinny goblins with a bounty of three coins each. Facing the demonic officers who were squeezing production and the miners who were on the verge of rioting, he thought he was getting a hell-level survival script - until he activated the [Material Blind Box System]. "What? A bowl of porridge and half a pack of pickled mustard, and these greenskins kneel down and call me the devil?!" When Xiao Yi replaced the swill that even dogs wouldn't eat with porridge and pickled mustard, the whole style of the mine suddenly changed - the goblins shouted "my king" with tears in their eyes, and the weak goblins evolved into rare elite berserkers by casually naming them! "Who said succubi can only be used as playthings? I want to build a city and become king!"
