The Trisolarans Who Returned to Zero

The Three-Body Problem: The Return of the Zeroers tells the story of humanity and the remnants of the Trisolaran civilization forming a fragile coexistence after the deterrence era ends. Lin Yun, the new-generation Swordholder, discovers that a cosmic civilization known as the Zeroers is about to erase both civilizations, with only 30 days left. Cheng Xin reveals that clues to the “Safety Declaration” left behind by Ye Wenjie and Luo Ji are hidden in four-dimensional fragments. For the first time, humanity and the Trisolarans truly work together, finding a civilization's safety vault inside a micro black hole at the edge of the Solar System. They discover that the Safety Declaration requires civilizations to restrict themselves in exchange for the right to survive. When a Trisolaran rebel fleet charges toward Earth with dimensional weapons, Lin Yun's team must solve the mystery of dimensions and complete a “safe leap” from three dimensions to four before civilization is destroyed. The story explores the price of a civilization's survival and the ultimate solution to the universe's dark forest rule.
