In the Xianyang Palace of the Great Qin Dynasty, Jing Ke assassinated the Qin Dynasty. The bug in history is Xia Wuji - he failed to use his medicine bag three times.
Carefully turn a lamp holder gasket to put the medicine bag on the right track of history. He calls this "returning."
But the price immediately appeared - at home two thousand years later, the ceiling fell into dust, the toilet was engraved with the Daqin crossbow logo, and his lover Tian Xiaotian picked up a stick to fight against the "logic cleaners" who came to erase his existence.
Every time Yan Qing repaired a line of code in ancient times, she would get another wound in this world.
"I want to talk to the world." Yan Jing said. "What if it doesn't listen?" Tian Xiaotian answered for him: "Then I will dismantle it first."
This is the story of a top actuary playing dice in the depths of history, while his wife takes all the bullets for him in this world.
