Gene Sequencing

In the 27th century, genetic technology has cut human beings into three layers—— The Purifier of Sky City, suspended in the clouds, breathing customized air. The hybrids in the underground city are crowded in the shadows, and sunlight is a luxury. The natives in the underground layer are illuminated by fluorescent moss, and their blood is drawn, collected and numbered regularly. Feng He is a "picked up child" in the seventh settlement. He thought he was an ordinary native until the Guangqi Project took away his best friend Ajiu, until he saw his genetic number deep in the archives of the Genetic Research Institute. He is from Sky City. His mother was crucified for hundreds of years and was the "mother" of the Golden Bough who continued the bloodline of the Purifiers. And the name she gave him was Crane. "Hopefully he can fly away." He flew away. Flying for hundreds of years. Now, he flies back. With a seed that can subvert the entire order. Its name is "Gold".
