Even after all the delay, Pavilion Master Chu didn't come over to the Time City to pick Song Shuhang and Chu Chu up.
Thereupon, Song Shuhang and Chu Chu explored the various passageways in the Time City, as well as the rooms, caves, and halls inside, after their daily training. They wanted to see if they could find a way to leave the Time City.
When Song Shuhang and Chu Chu entered the 'Time City', it was Pavilion Master Chu that brought them there. At that time, the restrictions and the maze of passages surrounding the Time City were in an inactive state. As such, it was going to be quite difficult if they wanted to get out of the Lower City of the Time City without Pavilion Master Chu's help.
In the blink of an eye, another two days passed.
Within these two days, Song Shuhang and Chu Chu explored nearly seventy rooms, halls, and caves... but they were still unable to find a way out of the Time City.
