As evening fell, Ling Chen instructed Chen Junfeng to take the team back first, while he and Tang Yuan stayed behind. All day, with everyone's concerted efforts, the area around the research institute had been thoroughly searched, but the location of the secret passage remained elusive.
Based on Ling Chen's judgement, the secret passage was likely located a considerable distance from the tomb chamber. Only in this way could He Zhishen secretly leave the tomb chamber without being noticed.
"Tang Yuan, if we keep searching like this, the area will get larger and the time will take longer. How about... I report to the higher-ups and have them send more personnel?"
"Alright, you'd better contact them soon and strive to redeploy people by tomorrow." After a pause, Ling Chen added, "Remember, we only need elites, no need to just add numbers."
"Don't worry, I know what to do."
