I, the Big Mouth Catfish, Am Looking for Immortality

"No heroine + no system + no invincibility + no holy mother + no golden-fingered grandpa" "If you let 1,000 large-mouthed catfish eat and refine each other at the same time, what changes will happen in the end!" Lao Liu never expected that he would be reincarnated into a large-mouthed catfish controlled by others and constantly being devoured and refined by his own people! As Lao Liu escaped, he discovered that the world was just a giant catfish tank, and everyone was biting and devouring each other like catfish! But the people who are fighting each other don't know that they are like weak catfish, being manipulated by the people in the upper world for the people in the upper world to play with. A play of God's will! The control of fate! Rewards from those in the upper world! Let's see how Lao Liu counter-controls God's will, destroys destiny, destroys the conspiracy of the people in the upper world, and looks for immortality in the shape of a catfish!
