This near-future science fiction novel set in 2157 depicts a world where human emotions are quantified, extracted and traded by technology. In this era dominated by new-age technology, "emotion" is no longer a private feeling, but an energy source that is visible, storable, and even deprivable. "Alien beasts" representing their own emotions will be embodied on people's heads, and the price of excessive extraction of emotions is that they gradually become transparent "emotionless shells".
The story revolves around the protagonist Ji Zheng, a symbiote with the unique ability "Silent Light Whale". He has won the battle against emotional exploitation, but he is also on the verge of the abyss of victory - he has become the core key of the emotional return device, and his body is gradually becoming transparent and heading towards nothingness due to the evaporation of emotions. As he floats in mid-air and feels increasingly disconnected from the world, the afterimages of his former partners and the first-generation symbionts bring about a crucial turning point: the "anchor" may not be the only one.
