Wang Yongzhu sat by the fire, occasionally throwing in some wood, lest the bonfire goes out.
You should know, on such a cold night, if the bonfire goes out, the people in this cave would probably fall ill from the cold.
Wang Yongzhu continued to poke at the fire, unable to sleep, she simply tried to summon Chen Xing in her mind.
Perhaps the frequent summoning had an effect, after a while, a crackling static noise appeared in her mind, mixed intermittently with Chen Xing's voice: "...zzzz... waiting... signal... zzzz... discovered..."
After that, there was no more signal, and silence filled her mind.
Wang Yongzhu pondered over those intermittent words for half a day, only able to guess that something was obstructing the signal, perhaps Chen Xing was asking her to wait patiently? Had the Alliance already noticed something was amiss?
But since she could already contact Chen Xing, he would naturally find a way, so she didn't need to worry, as she couldn't help much anyway.
