Chen Fei did not rush down to save them. Yu Shijin and his sister were merely in a somewhat dire situation now; they had not yet reached a life-or-death juncture.
And even if it were life or death, Chen Fei knew they would certainly have trump cards on them to save themselves.
A lineage-based force like the Yu Family might not possess more overall resources than the Immortal Cloud Sword Sect. It might even possess fewer.
Their overall resources were fewer, but the Yu Family also had fewer direct descendants. Divided among each person, the resources each of them possessed became exceedingly abundant.
Since the Yu siblings dared to travel outside, they certainly carried treasures that could help them escape danger. There was no need for Chen Fei to worry about their safety.
The clone separated from Chen Fei and silently entered the spiders' cavern.
These spiders were exceptionally sensitive to the aura and movements of living people, yet the clone possessed neither. Moreover, the spiders' attention was currently drawn to the Yu siblings, allowing Chen Fei's clone to penetrate deep into the cavern with great ease.
It was dark and damp. From time to time, Chen Fei saw countless little spiders biting and tearing at one another, as well as many spider eggs that were currently hatching.
Every spider egg trembled faintly, thick mucus coating the surroundings. Looking closely, one could seemingly see jointed limbs sliding about inside the eggs.
Chen Fei's expression remained unchanged, though he found it somewhat strange. Why could this place support the breeding of so many spider demons?
Quite a few of the spiders besieging Yu Shijin outside had been second rank. Otherwise, they could not have forcibly trapped two Early Stage Aperture Refining Realm cultivators in place, leaving them unable to break out.
