火星异种

Because of the deterioration of the earth's environment, human beings have to look for other living planets. So humans took Mars as their goal, and Mars immigration was put on the agenda. Humans first put cockroaches and algae plants on Mars, one is to make the Martian environment more suitable for human habitation, and the other is to test whether Mars can survive life with tenacious cockroaches. After that, the earth sent six astronauts to Mars to observe the situation and extract samples. Unexpectedly, due to climate and environmental reasons, cockroaches have mutated. Not only do they have a human-like form, but they also possess powerful destructive power and amazing defensive capabilities. The six wanted to resist but were instantly wiped out by the mutated cockroaches. As luck would have it, a cockroach body part is teleported to Earth for scientists to study. After they saw such terrifying creatures, they called them Martian aliens. And began to study their variation and countermeasures. Afterwards, humans started a battle with alien species on Mars..
