Chapter 161 - CHAPTER-161

This is a small fiery red planet. Before the footsteps of human beings set foot here, it has maintained desolation and loneliness for at least tens of millions to hundreds of millions of years. Originally, this number can be expanded to 4 billion years, which is the time when the solar system was born in the calculation, but even if human civilization has established a large base on Mars that can accommodate hundreds of thousands of people, humans still cannot be completely sure. Or rule out the possibility that life once existed on Mars. So, for the sake of rigor, this time frame should be delineated as tens of millions to hundreds of millions of years. At least, human civilization can be sure that no life has existed on Mars for the past tens to hundreds of millions of years.
