The protagonist Xiang Han was originally a guard in front of the First Emperor's palace. When he was looking for a way to live forever for the First Emperor, he was discovered by an alien civilization that his genes matched the set requirements and could be transformed into a molecular warrior. As a result, it was launched into a black hole and underwent inhumane transformation. Thousands of years have passed since this transformation.
When Xiang Han returned to the world, he discovered that everything had changed and he needed to start over. The First Emperor was gone, his family was gone, and his mission was gone. After thousands of years of struggle, the first thing he did when he came back was to face retirement.
Since there was nothing to do, he decided to learn more about the current society and live a good life again.
