All i remember is that the main hero goes to a magic circle for the purpose gaining a summoned creature. When he enters he goes in a bodyless state and after that starts calling out for his parner. Forgot to explain that this magic lets him connect with many dimensions. After some time someone returns the call and it gets summoned to his world. It is a baby lizard like thi g that later gets 2 heads? Regrettably thats all i remember

Shen Yin Wang Zuo (Novel)?
