Lin Xiao, in a twist of fate, finds himself transmigrated into the role of a foolish young lord. As a foolish young lord, he faces internal threats from a poison-wielding adopted brother and scornful servants, as well as external threats from ambitious feudal lords. Fortunately, he possesses a逆天summoning system, allowing him to summon historical heroes as his vanguard, gods and demons as his rearguard, and be accompanied by peerless beauties. His goal? To unify this different world!
