If You Give Me the Orb of All Souls at the Beginning, Then I Can Only Become Stronger.

This is a world where cultivation can only be done by contracted spirits. Each person can only contract with one spirit in his life. However, on the day Bai Chen turned eighteen, he unexpectedly received the All Souls Orb, also known as Linglong. Linglong can help Bai Chen break through limitations. Each time he reaches a higher realm, he can contract with one more spirit, until he can contract with all spirits.
