According to the plan of Su Jin and others, while Su Jin and two others went to the research institute for the rescue, Nie Qing and Mao Qiqi went to Cen Chu's team's residence to set up a Stealth Formation.
Nie Qing looked around and felt that the rooftop of the third floor was most suitable, as it was open and no one came by, so he asked Qiqi to wait downstairs. Unexpectedly, after he had finished setting up the formation, Qiqi was nowhere to be found.
Remembering the small blue dot that Mao Qiqi had been talking about these past few days, as well as the various strange things they had seen at this base, Nie Qing became somewhat restless. He notified Cen Chu and then went out along the dark streets to look for Mao Qiqi.
Meanwhile, Lu Hao, who had hidden himself in the Space, also got to know about Mao Qiqi's situation at first instance.
