Rebirth at the End of the World: I Am Not the Savior

Three years after the end of the world, I am the strongest seventh-level lightning power user in mankind. I defended the base, killed zombies, and protected my relatives and friends. I gave everything I had, but what I got in return was a stab in the back. My good brother took away my supplies, and my girlfriend abandoned me. The so-called hero is just a threat in the eyes of others. Once reborn, ten days before the red rain falls. In this life, I will not be a hero, a savior, or a white-eyed wolf. Stock up on billions of supplies, awaken top powers, and gather reliable partners. Those who betrayed me, harmed me, bullied me, and betrayed me in my previous life, In this life, I will allow you to repay your capital ten thousand times with interest! From now on, there will be no more human guardians in the world. There is only one who lives for himself!
