I traveled through hundreds of worlds at once

On the sentry tower of the fortress city wall late at night, several sentries on duty were chatting on the sentry tower.

Just as several sentries were floating around with binoculars, suddenly a sentry saw a white dot walking out of the distant forest out of the corner of his eye.

"Danger? Or an enemy?" The sentry squinted his eyes and looked in that direction. He could only barely see that the white figure seemed to be holding something in his hand from a distance of thousands of meters.

The sentry hurried to the sentry tower and took out the high-powered telescope for reconnaissance. Only then did he find that the white dot walking out of the forest was a person he had never seen before.
