Devouring Souls and Killing Demons

The most mysterious place in the Hunyuan Realm is called Devil's Valley. Due to the harsh environment here, the Zhengdao Sect throws demon cultivators and evildoers who have committed crimes into it, leaving them to fend for themselves. Nine hundred years ago, a bolide carrying a heaven-defying inheritance fell into it. Eighteen years ago, the abandoned baby Su Yang received this inheritance and came out of the valley carrying the evil old man's legacy. Step by step, he solves the grievances and resentments that have been hidden for nine hundred years, uncovers the mystery of his life experience, and gradually grows from a mortal with no cultivation to the strongest person in the three realms.
