Chang'an Xianlu

History professor Shen Zhiwei traveled to the Tang Dynasty, only to find that he had become the most dangerous profession - a cultivator of history. Holding a historical pen in your hand, you can change a single word and change the world; dyeing a long scroll with ink will cost you your longevity, and you will be hunted by the law of heaven. He wanted to be a quiet "historical recorder", until in the shadow of Lingyan Pavilion, he saw with his own eyes the Changsun Queen who was supposed to die of illness, coughing up blood and writing: "I know you are a variable." And the future empress Wu Zetian opened his door late at night, her fingertips skimmed over every word he wrote, and chuckled: "Shen Zhiwei, can your pen change the fate of this palace?"
