The earth was destroyed by a nuclear war more than 1,300 years ago. Some survivors discovered Aquamarine. Under the guidance of the mysterious Eagle Owl, Youyue, who was born into a mystery, gradually grew into a fighter, a special soldier, a mecha warrior, a resistance fighter, an empire king, and a planet founder. He moved step by step from the backward and poor Muma mountain village to the high-tech future city - the City of Angels. As his mind matured and his experience gained, he kept thinking about why the gap between the rich and the poor was so wide and the world was full of conflicts. It turns out that there is a secret force that controls the core power of Aquamarine. They keep mankind in constant disputes and conflicts, so as to curb human selfishness, greed and excessive reproduction... Aquamarine will not repeat the mistakes of the earth's destruction. The secret forces are extremely powerful and it is extremely difficult to defeat them. When Youyue faced his ultimate enemy-the "immortal", he found that the opponent could never be killed. It turns out that his memory can be copied in the brain of Warcraft. As long as his memory still exists, the world will never have peace...
