The First Mechanic of the End of the World

In 2100, after the Third World War, the earth ushered in an era of catastrophe. After the first nuclear weapon was launched, nuclear weapons all over the world were launched simultaneously in a very short period of time. Only the ruins of the former high-rise buildings were left, and the earth was devastated. After the nuclear war, the world's animals and plants began to undergo catastrophic changes. All animals and plants broke through their genetic locks and became the overlords of the earth again. Volcanoes and tsunamis erupted at the same time, and extreme weather became the norm. The world's population has dropped sharply, and humans are struggling to survive. Zhang Mingyuan came with a mechanical heart to lead mankind to re-establish civilization.
