Homecoming: the Martian Age

My name is Lin Ye, the commander of Ark-3. I escaped to Mars with the last fire of mankind. I thought I was one of the first visitors to Mars, until that dust storm buried me under the red desert. There were seven hours of oxygen left, the leg was crushed, there was just a rustle in the communicator - and then a signal came from underground. Once a second, like a heartbeat. Buried underground on Mars is a metal ball engraved with mathematical rules. It says it has been waiting for us for four billion years. It said that life on earth started from Mars, evolved for four billion years, and finally returned home. We are not here to conquer Mars. We are homecomings. But Mars isn't just the remnants of ancient civilizations. When 20,000 human survivors built a new home in Homecoming City, a man named Cheng Yu began to tear it all apart in secret - he said that Mars does not belong to anyone, so whoever has a strong fist belongs to him. The Martians perished not from natural disasters but from internal strife. This time, can we be different?
