Doomsday Ranch: Return from a Failed Future

In 2077, the alien civilization Azathoth descended on the earth and transformed the entire planet into a pasture of life. Sixty percent of humanity has been alienated, and the first war of resistance failed miserably. The elite fled to Gaia, and those who stayed behind hid underground and called themselves the Fire. Three years later, the six shepherds came. They pollute the land, devour the oceans, suppress technology, block the sky, control the spirit, and transform the atmosphere. Humans think they are survivors. Later I learned that the entire earth was in captivity. Chen Jin comes from a failed future. In the last life, mankind perished, Gaia fell, and the earth was completely sucked dry. In this life, he merged with the "reverse species" born in Azathoth, returned to the night when the Six Kings came, and awakened the first-generation mecha that was judged to be a failure - Zhulong. From ruin scavengers to Earth's counter-attack force. From the fire of the underground, to the god-slayer of the stars. What Chen Jin wants to do is not to lead mankind to escape the doomsday. Instead, he took the entire earth and attacked the herdsman.
