Use a Time Machine to Become an Immortal

In 2538, the earth's civilization collapsed. The protagonist Wu Zheng drove a time machine to carry out a salvation mission. Although the time machine exceeded the speed of light, it still did not open a wormhole in the universe and travel through the past. Instead, he accidentally came to the world of a civilization that cultivated immortals in another galaxy. This realm is divided into three levels: mortal, cultivator, and immortal. The sects are divided, the spiritual veins are monopolized, and the weak eat the strong. Only by becoming an immortal can one transcend life and death. The protagonist, based on earth's technology, embarks on a unique path of technological immortality, subverting the traditional system of immortality. The ultimate goal is to become an immortal, return to Earth, and save the world.
