In order to perform the Sealing Verification for a flood dragon traveling along the river, one must have an extremely unique fate chart.
And a person with a unique fate chart would emit a different kind of Qi compared to ordinary people.
What Shu Guan observed was the Qi of everyone in Pen City, determining if there was anyone with a unique fate chart.
Although Pen City was small, it had a population of nearly a hundred thousand. In addition to the merchants coming and going on the river, it also served as a rest stop, so at that time, there were more than a hundred thousand commoners in the city.
Observing the Qi of so many people at once was not easy.
However, Shu Guan possessed a mysterious ability to incredibly excel in any Daoist skill, revealing the original power of a Daoist skill from ancient times.
Having spent the past several days observing the Qi of the mountains and rivers, he had become familiar with the Observing Qi Skill.
