After confirming that Yue Siqing had left, Baili Hongzhuang and Di Beichen quickly entered Yue Siqing's room.
Previously, they had inadvertently released a slight breath, and Yue Siqing had already noticed it, indicating how high her vigilance was.
Although Yue Siqing had left for the banquet, there was a possibility that she would return at any time.
After all, apart from the opening, the banquet was not particularly important, and one could leave whenever they wanted.
Based on their assessment of Yue Siqing, she was likely to be concerned about this matter, so they didn't have much time and needed to act quickly.
Baili Hongzhuang and Di Beichen swiftly entered the room at lightning speed. Yue Siqing's room was not small, but it was filled with many things, making it appear crowded.
Baili Hongzhuang could tell from just a glance that this was the characteristic of a physician.
It seemed that Yue Siqing's medical skills were indeed quite high. Otherwise, she wouldn't have so many things, unless she was extremely passionate about medicine.
However, Baili Hongzhuang's focus was not on these things at the moment. What she cared about was how to find the switch to enter the dungeon.
Di Beichen and Baili Hongzhuang searched the room but didn't find any underground passage.
Evidently, Yue Siqing had set up a special mechanism.
If they didn't find the location of that mechanism, they wouldn't be able to approach the passage.
Di Beichen and Baili Hongzhuang immediately began searching the room. No wonder Yue Siqing had managed to keep Lan Yunxiao and Mu Lingbing imprisoned for so long without being discovered. The mechanism must have been cleverly hidden.
Di Beichen searched the places where mechanisms were commonly placed, but even after trying each one, he couldn't find the switch.
As time ticked away, beads of sweat appeared on Baili Hongzhuang and Di Beichen's foreheads.
This was something they hadn't anticipated before.
Shi Tian Tower could only help them determine the location but didn't provide an opportunity to search for the mechanism.
Similarly, they hadn't expected that finding the mechanism would be so difficult for Yue Siqing.
"I've searched all the places I can think of, but I haven't found the switch," Di Beichen furrowed his brows. Normally, this kind of situation wouldn't occur.
However, no matter how hard he tried now, he couldn't obtain any results. Where could the mechanism be?
Baili Hongzhuang's eyes also filled with a hint of puzzlement. Even after searching the room, she hadn't noticed the location of the mechanism. It was too strange.
Although the room wasn't small, these were the only items that could possibly conceal a mechanism. Could there be something they had overlooked?
Time was running out, and although Baili Hongzhuang was extremely anxious, she forced herself to calm down.
If she lost her composure at a time like this, it would be over.
While pondering, Baili Hongzhuang's gaze quietly fell on the table where Yue Siqing kept the medicinal herbs.
Baili Hongzhuang's eyebrows suddenly furrowed because she had noticed a peculiar herb among the medicinal herbs—Wuwei Grass.
Wuwei Grass was a unique herb with average effects, mainly used for harmonizing the properties of other herbs.
Baili Hongzhuang wouldn't have paid attention to Wuwei Grass normally, but it was placed next to a Qingmi Flower.
When Wuwei Grass and Qingmi Flower were placed together, it could affect the properties of the herbs.
Therefore, ordinary physicians wouldn't put these two herbs together, and Baili Hongzhuang believed that Yue Siqing wouldn't do so either.
