It was past ten at night.
By this hour, Hogan City had already fallen asleep.
Apart from the few drunkards and certain special professions that only came out at night, most people were already fast asleep at home rather than wandering outside.
The night was very quiet, broken only occasionally by birdsong, insect chirps, or the noise made by drunkards.
Gao De quietly left the medicinal garden through the rear courtyard, his footsteps light as he headed swiftly toward the city center.
Crossing the filthy, chaotic slums, he occasionally spotted a few figures along the way.
There were no shortage of restless people in the slums at night.
Before long, Gao De arrived in the relatively safer and much cleaner commoners' district.
After every trip to sell medicine, he had wandered around Hogan City.
Thus, compared to when he had first arrived in this world, Gao De was now quite familiar with Hogan City.
So Gao De quickly found the target of this trip.
A sewer entrance located in the commoners' district.
Gao De swept his gaze around and quickly found a suitable spot.
Directly across from the sewer entrance stood a roadside tree with luxuriant branches and leaves.
He swiftly approached the tree, drew on his childhood tree-climbing experience, and climbed up in a few quick moves, hiding himself within the tree's shadow.
Only after confirming that the roadside tree's branches and leaves concealed him tightly, without letting even the slightest trace—not even a shadow—leak out did Gao De carefully part the branches and stare fixedly at the sewer entrance.
His purpose here was obvious:
To carry out one final verification of his guess, and to try to uncover the true identity of the "mastermind" behind the strange happenings in the city.
There were not especially many sewer entrances
