This Killing God Is a Bit Strong

My Dantian was crippled, and my family threw me into a "living human poison field" - a hundred cripples killed each other, and the one who survived was rewarded with a tube of inferior genetic fluid. I thought I was dead. Until I killed the first person. Bite! The Tiansha destiny is activated - killing people will make you stronger, with no upper limit. The more I kill, the stronger I become. But the more I forget, the more I forget. From my mother's laughter, to my first love's name, to the rainy night when I was seven years old—— Every time someone is killed, the memory is shattered into pieces. Someone warned me: If you kill thousands of people, you will become a puppet of the evil spirits and will not recognize your relatives. But if I don't kill, the world will be destroyed. The seventh shard is waiting for me. The girl who held an umbrella for me in the rain when I was seven years old is also waiting for me. In this life, before I forget "who I am"—— First change the rules of this world. Killer God? No. This time, I want to be the "laughing god".
