I Open My Mouth at the Beginning and Become Stronger by Eating Evil Ghosts

[Funny and easy + no heroine + invincible at the same stage + numerical monsters + ghosts + cool writing + fast pace] The break of reincarnation has naturally caused chaos in the human world. Human-eating ghosts may appear in high-rise buildings or in the wilderness. Who is the demented boy that Ju Lingsi found in the suburbs? His name is Yin Hui, what is he? Well... Ghost eaters. Ghosts hunt for humans, and the reverse seems to be true, right? What happened if I ate something? Crunchy and still tastes like chicken! I am an alien who does not belong to human beings or ghosts. If you eat some ghost crystals, you will say that I am neither fish nor fowl. What happened to being stronger? Is it illegal? What's wrong with the higher value? IQ is exchanged for it! Please don't look at me with such strange eyes, these are my crunchy snacks, how could they be ghosts!
