Echoes of the Moon

I just finished Chiling Medicine Valley, and I had endless reveries about the moon, so I wrote this book. Thank you for your support~ In the 22nd century AD, humans established a permanent base "Guanghan Palace" on the moon's "Sea of Tranquility". During a routine lunar seismic survey, young geologist Chen Xing and his team accidentally triggered an ancient mechanism buried deep under the lunar crust, revealing the shocking truth about the moon: The moon is not a natural celestial body, but a super man-made object created by ancient advanced civilizations. Its shell is indestructible and its interior is hollow. It is a world that accommodates another ecological and civilization system. What's even more shocking is that the "core" of the moon is not a hot iron core, but a self-aware artificial intelligence called the "Galaxy Core", which has silently observed and guided the evolution of life on earth for billions of years. As the exploration deepens, a cosmic war epic that has been dusted by history gradually emerges - the moon is the ultimate refuge and starship built by the "Guardian" civilization to protect the nascent life on Earth from the invasion of an ancient evil "Reaper" who lives by devouring living planets. Now, a distant threat has reawakened and is approaching the solar system. The "Moon Descent" civilization inside the moon has serious differences over whether to continue to protect mankind. At the same time, in order to compete for the infinite technology contained in the moon, the forces of various countries on the earth have also begun to fight openly and secretly, even at the risk of conducting dangerous transactions with the "Reapers".
