Although their strength is close to top-tier, the Nest Spider's usage of power is far inferior to Zhao Guang's.
Or rather, all magical beasts are like this in their usage of power.
Under Zhao Guang's spatial power confinement, the Nest Spider's energy depletes rapidly. Spiders from the surroundings continuously try to attack, but are all blocked by Zhao Guang's clone and Sephidya.
The Nest Spider has indeed been operating here for a long time, but none of these small spiders are powerful.
Even combined, they can only threaten ordinary Legends; faced with Sephidya and Zhao Guang's clone, they are no match.
In two days, the small spiders were nearly cleared away, along with all the nests in the vicinity being burned down.
If Zhao Guang wasn't worried about harming the Nest Spider, he would have crippled it by now. After another three days, the Nest Spider gradually settled down, not out of willingness, but simply because it had no energy left.
