Which novels described how the game system invaded Earth?

I recommend the sci-fi space and futuristic novel,"The Illustrated Guide to Doomsday Monsters in the Future." The story took place thousands of years after the 21st century. Earth was invaded by alien creatures and all kinds of monsters invaded Earth. Some humans escaped the control of the monsters and struggled to survive outside, while humans also established various organizations to save themselves and seek equality. The story began with the private organization, the Taming Human Rescue Center. It described the confrontation between humans and monsters and the difficult path of survival for the survivors. The novel was also similar to the plot of the computer turning into a monster mentioned in the question. I hope you like this fairy's recommendation. Muah ~😗

I am currently unable to provide any novel recommendations regarding the invasion of the Earth and the male protagonist's anime system. According to my knowledge, this type of novel is more common, but the specific content needs to be determined according to the author and plot.

😋I recommend to you I Must Become Stronger. This is a fantasy novel about a high-level martial arts world. The plot of the novel was that Earth was about to be invaded by another world. In order to protect Earth and become stronger, the protagonist traveled through different worlds in pursuit of unlimited ambition. It showed a story of becoming a strong person. I hope you like this fairy's recommendation. Muah ~😗

I recommend the novel " Interstellar Mecha Invasion " to you! The background of the story was that the earthlings invaded the aliens in an entertainment way and killed the living aliens. But in fact, humans themselves had become the target of other civilizations. This novel is very suitable for your needs. I hope you will like it!😋

" Xu Fu Reborn on Earth " told the story of Xu Fu, an expert from the cultivation world, who transmigrated to Earth and experienced all kinds of life and death tests to become an immortal. I recommend this book to you. I hope you like this fairy's recommendation.😗

The cat invasion of the Earth-themed pavilion could be a very interesting novel plot. In this story, cats suddenly appeared on Earth and occupied the Earth theme museum at an extremely fast speed, causing everyone in the museum to be frightened and confused. Cats might invade the Earth themed museum in various ways, such as through the exhibition of items or through the communication between the people in the museum. The cat may also use its powerful strength to destroy the facilities in the museum and attack and plunder the people in the museum. At the end of the story, the cat may be punished by Earth for occupying the Earth theme pavilion, or it may leave Earth and return to its own life because it cannot adapt to the Earth's environment.

The following two novels meet the requirements: 1. " Universe Galaxy ": The protagonist, Du Yun, entered the Other World from Earth. Twenty-two years later, he was trapped and self-destructed before returning to Earth again. In the face of demonic beasts and natural and man-made disasters, how did he run rampant on Earth? 2. " Special Homo Evolutis ": The protagonist Fang Xing returns to Earth thirty years after leaving it, only to find that it has become an apocalyptic scene. He has no choice but to take on the responsibility of saving mankind.

Humans would probably be very scared at first. They would see these strange creatures and not know what to do.

😋I recommend the Interstellar Living Empire to you. The protagonist of this novel was an Earthling. Through the development of biotechnology and the use of extraterrestrial technology, they rushed out of Earth and migrated to the galaxy. However, in the interstellar war in the Milky Way, Earth faced danger again. The protagonist stepped forward and continued to expand into the universe to establish a huge interstellar biological empire. I hope you like this fairy's recommendation. Muah ~😗

I recommend the following novels to you. They are all about the battle between humans and aliens on Earth: " The Battle of the Solar System "," Superweapons "," Supreme Starry Sky "," Ace of Dawn "," Interstellar Mecha Invasion ", and " Earth Destruction Plan ". The above novels were all sci-fi-futuristic or sci-fi-interstellar novels, full of exciting battles and intense interpersonal relationships. I hope you like my recommendation.😗
