King's Title Designation

After bringing the FeGO summoning system to another world and becoming a little king, Mu Jinran realized that something was wrong with his summoning system. "Master, I am the only one." Nero. "Presumptuous! Who allowed you to be so shameless!" Ying Zheng. "What needs to be done must be what all people want." Du Mao. "The strong wind is blowing and the dust is flying!" Liu Bang. "I say, everyone sitting here is a jerk." Liu Che said arrogantly. This is a story about a system that can only summon a mother-in-law emperor to conquer another world.
