My Brother Is Actually the Immortal Emperor?

Travel through the spiritual world and become the Immortal Emperor. After Qin Chao returned, he set several rules for himself. First: Don't kill unless necessary! (As for the skill, Qin Chao is a fellow practitioner of immortals and demons. The human world is too fragile. If Qin Chao cannot restrain his murderous intention, it will be a devastating disaster.) Second: Unless necessary, do not crush with realm! (Anyone who has played stand-alone games knows that cheating will only affect the life of the game! It is more interesting to compete in the same realm!) Third: The human world does not need immortal cultivators! (Qin Chao is a cultivator of immortals, and he knows the ruthlessness of cultivators best! He wants to eliminate all opportunities to become immortals in the human world, leaving only mortals in the human world!) . . . . . . Finally: the ultimate lover king! (Qin Chao must protect the human world no matter what! As for the reason, Qin Chao himself doesn't know.) —————— The protagonist doesn't know how to kill, please don't comment if you mind, thank you! But there is a reason for the 'Holy Mother' displayed by the Qin Dynasty! As the plot develops, it will be explained slowly.
