I stack buffs in a weird world!

Story of: I stack buffs in a weird world!

[Decisive Killing + Mutation Evolution + Dark Text + Weird Cthulhu + Evil God + Indescribable] Monsters are rampant in this world, weird things appear frequently, and evil spirits are like crucian carp crossing the river, as if they regard this world as a plaything. Humans living in this world are like ants and may die at any time. This is a world where not only people eat people, but also weird things eat people, and the world also eats people. Weird moons and strange suns, and many stars. The weird world is ruled by three forces: Dan Gui, Gu Chong, Yin Fu, Poison God, Zombie Cultivator, Shanchang, Famine, Wu Media, Sanshi, and Xing Chong... Various forces are intricately intertwined. Zhang Yang traveled through this weird world with the BUUF system, and one BUFF after another was added to him. Looking back, he suddenly discovered that the biggest evil god in this world was actually himself! (The introduction is weak, please enter the text...)
