Looking Back, You Are Already a Part of History

If history were no longer boring words in books, but real memories that could be "relived" in person - what would you choose to see? Lin Shen, a young neuroscientist who proved the existence of the "historical empathy circuit", joined the mysterious cultural heritage protection organization "Longsun". Here, he saw the "resonance cabin" built at a cost of 2.3 Billion - a machine that allows users to travel through time and space from a first-person perspective and experience all the emotions of historical parties. When the first soil sample from the Terracotta Warriors and Horses pit was put into the cabin, a nineteen-year-old craftsman named "Jiang" woke up from a 2,200-year-old slumber. He missed home and his mother, who had bad eyesight, and he knew he could never go back. A drop of blood, a name, an ordinary life that has been buried for thousands of years by a grand narrative. From the broken porcelain pieces of the kiln worker's wife in the Southern Song Dynasty, to the blood-stained gravel of the unknown soldiers of the Ming Dynasty, to the recitation of "Li Sao" amidst the bombing of the Southwest Associated University - the "Echo" project awakens not only the memory of history, but also the innate empathy and identity in everyone's heart. But the more powerful the technology, the more deadly the risks. Who has the right to define "historical truth"? When emotion intervenes, will objectivity withdraw? Will fake memories become a new weapon? "Tracing Light" is a novel that combines science fiction, history and humanistic thinking. While questioning the ethics of technology, it also strikes a simple yet profound belief: to understand the future, we must first understand the past. That is to say, we are colleagues and we will carve historical chapters together. And you are already part of history.
