The System Copy Starts from the Spell Return Battle

Xia Cang, who traveled to the barbaric era, became the leader of a tribe, but the tribal civilization in this world has come to an end. "Clan leader, in another month, the power of the totem will disappear, and the ferocious beasts outside will tear us apart." When Xia Cang was in despair, the copy system came. Ps: The first copy is "Spell Return", which can be understood by those who have never seen Spell.
