I Am Like a God in the World of High Martial Arts

This story is purely fictitious. The author is a newbie who doesn't like it. He is good at martial arts, unsystematic, decisive in killing, not holy, and won't fight too many times. The story takes place on Blue Star: In 2100, a terrible earthquake suddenly erupted on Blue Star, which lasted for three months. The earthquake finally stopped one day three months later, which was when humans were thankful. Suddenly, various animals appeared from the earthquake cracks, including lions, tigers, elephants, zebras, etc... At first people didn't care, thinking they were ordinary creatures. But I never thought that these animals would start killing humans for food. After this incident, humans sent troops to suppress the animals. But they never thought that human armies and thermal weapons would not be effective against them. Human beings began to flee one after another, and within a few months, human settlements shrank by two-thirds. Fortunately, several countries on Blue Star worked together to develop a potion that enhances human strength. From then on, humans began to have a profession of warriors. Just become a warrior. You can enjoy glory and wealth, and it is also only after the birth of human beings that warriors can successfully resist the attacks of monsters. After fifty years, humans and monsters have come and gone. In the end, humans and alien beasts ceased war. Humans used Tianmen Pass in the north as the boundary to fight against the demon beasts. Likewise, the demon beasts lived outside Tianmen Pass and did not invade each other for the time being. The cultivation realms of both humans and monsters are from one to nine levels (the first to fifth levels are warriors, the sixth level is Martial King, the seventh level is Martial Emperor, the eighth level is Martial Saint, and the ninth level is Martial Emperor. The same goes for monsters.)
