Star Abyss, Earth Core Dome People

"The People of the Earth's Core" Two hundred and eighty million years ago, Yuan human civilization collapsed due to civil war. Some of them fled into the center of the earth and became "domestic people", while others took starships to travel to the stars. Two hundred and eighty million years later, Lin Ye, a geological engineer for humans on the surface, received an encrypted email from the underground - the sender was his mother who "died" ten years ago. In order to find his missing parents, Lin Ye drilled deep into Siberia and passed through the magma plains and crystal forests of the mantle. He was captured by the dome people and taken to the floating city in the outer core of the earth. There, he learned the shocking truth: the industrial activities of humans on the surface were tearing apart the earth's veins, and the homes of the dome people were collapsing. His parents had already discovered all this, but were imprisoned deep in the mantle by the Joint Survey Bureau. From the center of the earth to the interstellar space, from a 10,000-meter-deep hole to a metahuman colony four hundred light years away, Lin Ye gradually uncovered the secrets of the heaven and earth cycle formation. Not only does he want to save his parents, but he also wants to prevent the two civilizations from going to destruction and restart the last symbiosis contract on the earth.
