Having No Choice but to Travel Through Time, I Rely on Killing Monsters to Become Invincible

Li Xiyi, a second-generation rich man, had just finished negotiating a multi-billion dollar project in a hotel when he suddenly realized that he had traveled through time. What to do? What to do? My dad's pig farm, several houses, several cars, and fifty acres of land are gone? ! Li Xiyi wanted to cry but had no tears. But God still favored him. He didn't have a father, but gave him a mobile phone father so that he could kill monsters and become stronger. At this point, he has embarked on a road to become an invincible peak power by killing monsters. "As long as I'm here, you monsters, monsters, ghosts, and devils can't even think about causing harm to the world!"
