My Beasts Are All Childhood Memories

This is a world where everyone summons the beast. All beasts originate from a mysterious space called "The Rift of All Realms". The protagonist Lu Ming appears to be an ordinary high school student, but in fact his soul comes from the earth. His beast-control identity card is unique and can summon a combination of "childhood memories" you specify. These beasts are actually the remnants of a lost civilization deep in the rift of the world. This novel and its characters are purely fictitious.
