Kill Demons? Wait for Me to Touch the Magical Power First!

There are all kinds of laws in heaven and earth, waiting only for those who are destined to do so. After waking up from another world, Su Yan became a policeman in Yushui County. In this world where demons are everywhere and evil spirits are everywhere, Su Yan wields a knife at the demons as a mortal, guarding the last glimmer of light in the numb eyes of all living beings. Every time a monk makes a breakthrough, he needs to create a magical power, and people with special physiques are born with their own magical powers. Although Su Yan is in mortal form, he can have infinite access to their magical powers! From the natal magical power [Shadow Reverse Space] to the foundation-building magical power [Tiger Roar and Broken Soul]; From the golden elixir magical power [Instant Space Transformation Technique] to the Nascent Soul magical power [Yin Yang Creation Technique]! … Su Yan often fell into deep thought, why can't all the demons in this world be eradicated? Many years later, when Su Yan stepped onto the ladder to heaven and looked into the depths of the sea of clouds, he saw densely covered animal scales under the golden light of the gods and Buddhas in the sky... "Why can't I find the source of the pollution? It turns out that the gods are sitting on the tower of heaven, and they don't care to see the world as a prison!"
