There's Something Wrong with This Secret

The soul of a prostitute traveled to a young man in another world. He obtained a fused soul, and thus accidentally obtained a magical fused spirit body! He can actually use the other party's abilities and obtain the other party's secrets for free! So this is your secret! Since then, various magical fighting methods have continued to unfold. He originally wanted to be a happy and optimistic tourist in a different world, but gradually discovered that this world was not as simple as he imagined. The truth about his parents' sacrifice; the spiritual beasts that are eyeing humans; the terrifying organizations hidden among humans... Are all constantly stimulating him to become stronger! What kind of story will he stage with his strange abilities? Non-systematic novel; there will be female protagonists in the early stage, but the number will drop sharply in the middle period; ordinary sand sculpture novel. (The original title of the book is "I Know You Well", a new work by a newcomer, please take care of me! I will read every comment you make carefully!)
