Homeward Bound: Star Road

In 2580, Wei Yan, an engineer at the Guanghan Palace Base on the Moon, was involved in a truth that subverted human cognition when he was involved in a mysterious metal part from 100,000 years ago during routine maintenance. From the abnormal gravity under the moon, to the 11-kilometer giant metal wall on the Pacific Ocean floor, to the giant sphere suspended deep in the earth's core - he and archaeologist Cheng Huan revealed step by step: the earth and the moon are not natural celestial bodies, but interstellar spacecraft left behind by the "star builders" of advanced civilizations 100,000 years ago. Humanity is not an accident of natural evolution, but a sown "seed"; the huge structure deep in the earth and moon is the engine and center that has been sleeping for a hundred thousand years; at the end of the star map spanning the galaxy, lies the true origin and return of humankind. When the sleeping spacecraft was awakened and the stargate reopened, Wei Yan and the human advance team drove the homing ship and embarked on a journey back to the source of civilization. This is not an expedition, but a homecoming.
