Black God: Endless Arms

In 2147, the solar system was eroded by a high-dimensional energy storm, the global magnetic field was disrupted, machines malfunctioned, and civilization fell. A mysterious energy called "eclipse" penetrates the earth, triggering crazy mutations of species - monsters called "abnormal beasts" sweep across the city, and humans retreat to the last nine fortresses. Lin Shen, an S-class gunner who struggled to survive for three years in the last days, accidentally detonated an ancient ruins when the last fortress fell, and died together with a mysterious mecha code-named "Black God". When he opened his eyes again, he returned to ten years ago - 48 hours before the end of the world. The reborn Lin Shen discovered that the "eclipse" that was regarded as the source of disaster in his previous life was actually the key to unlocking the door to human evolution; and the Black God Mecha was the core platform to unlock the key. This time, he wants to get ahead of all forces, use his foresight to plunder resources, control mechas, activate the "energy erosion" system, and lead mankind to jump from the mortal body to the "erosion of weapons era". However, he soon discovered that he was not the only one to be reborn. Those "watchers" who have existed since ancient times have already been deployed on various timelines. Humanity's destiny has never been truly in its own hands.
