More than three thousand years ago, mankind's Third World War made the earth unviable, and the surviving earthlings took spaceships to travel into space.
After three thousand years of space travel, humans have arrived at a planet called Nasha. Although the indigenous people here are tall and powerful, they have ugly faces.
In order to pass down civilization on the planet Nasha, the people on Earth started with good intentions.
Unexpectedly, after hundreds of years, the technology brought by the earth people made all humans on the planet live a good life, but the Nasha planet and the earth people also had a war because of the competition for resources, and the Nasha planet wanted to expel the earth people.
The Nasha people captured the earth's technology laboratory, fell into the trap set by the earth, and unexpectedly gained immortality. However, the side effect of immortality was that they were unable to reproduce.
Gradually, the Nasha people discovered that as long as they sucked the flesh and blood of people on Earth, they could live forever and reproduce.
As a result, the Nasha planets arrested people on earth, and countless people on earth were brutally murdered.
In the end, there were no more than ten people on earth, and the Nasha people decided to take a time machine to the earth more than 3,000 years ago. At this time, the number of people on earth was still more than 10 billion.
After the people on Earth on Nasha learned the news, they formed a team to take a time machine back to more than 3,000 years ago to save the earth.
The female protagonist Ni Bu is one of the team members. After traveling through time, she met the male protagonist Lin Bei who was at a low point. Lin Bei's life also changed due to Ni Bu's arrival...
