Player Enemies of Human Extinction

In the year 2333 of the Fire Calendar, alien creatures invaded the earth. Humanity was retreating steadily and was on the verge of extinction. After untold hardships, the great scientist Mr. Lin Chi finally created a biological organism that could compete with the combat power of alien creatures, and the war situation was reversed. However, an accident happened and Mr. Lin Chi was stabbed to death. Alien creatures also created more terrifying mechanical creatures to fight against humans. Human beings who lost all their territory left only all biological organisms on the earth to continue fighting against alien forces, while they themselves fled to the moon base. Hundreds of years later, it was all over. A human being called "Firefly" came to this desolate and ruined world. This novel and its characters are purely fictitious.
