Lu Zhen's mission, as given by Sato, was simply to wreak havoc and destruction all around, making it so that all the kobolds present would unequivocally hate him. With their aggro set on him, he would then depart from the settlement and draw the monsters towards Emperor's Might and Heaven's Angels' God's Retaliation battalion unit. From an overview, the mission looked easy, but in actual sense, it was filled with risks here and there.
