Although Eris used the Cleaning Spell to remove the blue spider blood on her body and get rid of the unpleasant odor, she didn't heal the wound on her left leg bitten by a juvenile Acromantula.
Even though the wound was minor and Eris wasn't bleeding non - stop, the presence of the wound would inevitably keep spreading the smell of human blood and the residual venom of the juvenile Acromantula.
Other Acromantulas must be extremely sensitive to this smell.
And Eris, who was maintaining the Invisibility Charm, couldn't constantly cast the Cleaning Spell on herself to eliminate the smell.
She didn't even think of this aspect at all.
Not even Dudley thought of it immediately.
This explains why the Acromantulas could sense the location of Eris under the Invisibility Charm.
At that time, after Dudley figured this out, he immediately remotely controlled two Acromantulas under the Imperius Curse to quickly run to the nearest safe house and prepare an ambush for Eris.
Unexpectedly, there was already a clever Acromantula that had woven a thick web and was lying on it.
This didn't match the new home location arranged by the wizards for any adult Acromantula.
Obviously, some Acromantulas craving human flesh couldn't even wait for the maze to be completely improved. They wove webs near the safe house and waited for the wizards to come, just like waiting for takeout.
Dudley immediately controlled the two Acromantulas to drive the gluttonous web - weaving spider down and chased it aside together.
After that, he controlled one Acromantula to pierce the upper part of the large spider web, crawl in, lie on the ground behind the web and silently gather strength, preparing for a sneak attack.
The other controlled Acromantula spat silk to weave and patched up the damaged upper part of the web.
This is why after Eris arrived, she found that the upper part of the spider web was sparse and the lower part was dense, looking like an unfinished semi - product.
Originally, Dudley thought that after Eris killed the Acromantula that wove the web to block the way, she would break all the spider webs before moving forward.
He planned to control the Acromantula behind the web to directly launch a surprise attack after the web was broken and pounce on Eris's face. Caught off - guard, Eris was very likely to be hurt.
Even if it couldn't hurt Eris, it could still push her back and make her panic, thus affecting the effect of the protective incantation Eris had cast before, and buying time and opportunities for other Acromantulas to form a pincer attack again.
At that time, there would definitely be more Acromantulas gathered. Charging forward together, they would surely be able to hurt Eris.
If this still couldn't hurt her, Dudley would have to think of other ways.
But as it turned out, things went very smoothly.
After Eris killed one Acromantula, she actually slackened.
She only roughly made a big hole in the middle of the spider web, didn't even check the situation inside, and dared to lift her leg and step in.
Of course, Dudley wouldn't miss such a good opportunity. He controlled the Acromantula hiding inside to bite most of Eris's left leg into its mouth and achieved his goal.
Now that the goal had been achieved, he was going to rescue this unlucky female professor.
We can't let Eris really die. Otherwise, Voldemort's main soul will run away again, find a new host, and slip out of Dudley and Dumbledore's control.
Dudley put away the 'Water in the Bottle' monitor again. He cast a powerful Shield Charm on himself, then cast the Invisibility Charm again. Waving the Smelting stick, he pushed aside the constantly surging Acromantulas and headed towards the maze corridor where Eris and the safe house were.
The news of Eris must have spread among the Acromantula colony in the maze. Even though the webs blocked the way and her scent was faint and hard to distinguish, it didn't affect the Acromantulas gathering here at all.
Now, it was a situation where Acromantulas were on top of each other. There were Acromantulas above, below, in front, behind, on the left, and on the right.
Dudley, shielded and invisible, relying solely on his powerful physical strength nourished by the Strength Enhancement spell, pushed aside the surrounding Acromantulas and walked forward slowly.
Most of the Acromantulas would take this as the pushing and shoving between their own kind, and it wouldn't attract too much attention.
As long as he entered that corridor, broke through the web wall, dragged the seriously injured and poisoned Eris into the safe house, he could escape from the maze through the reserved passage above the safe house and bring this operation to a successful end.
But reality wouldn't always develop according to Dudley's plan.
"Expecto Patronum!"
A gloomy male voice sounded. A silver - hind patronus shone with white light and trotted nimbly through the maze corridor, driving and intimidating the Acromantulas.
It was Snape!
Dudley realized this and frowned. He walked to a wall and leaned against it, pausing his action. Then he took out the 'Water in the Bottle' monitor to check Eris's current situation.
"Do you want to break the agreement and attack the people in the school? If you don't stop and make way, you'll all be hit by Sectumsempra!"
Snape's gloomy and venomous voice echoed through the nearby maze corridor, along with the beautiful silver - hind patronus.
This made the Acromantula colony hesitate. Since their plan hadn't reached the stage of reaping the rewards and they hadn't tasted the fresh wizard meat yet, if they launched an attack now, they could only get one man and one woman at most, and the meat wouldn't be enough to share.
Moreover, they had witnessed the strength of this poker - faced professor. If they really fought, they didn't know how many of their kin they would lose, and maybe they would be the ones to die.
"Zzzz -"
Aragog's old screech resounded throughout the colony once more.
Those rebellious ones in the Acromantula group became obedient good - boys again.
They were just wondering how to negotiate with this powerful wizard!
At this time, the old and undead spider ancestor could come in handy.
"Human!"
Aragog moved his old and huge body and slowly walked towards Snape, who was surrounded by the patronus, through the path made by the other Acromantulas. He let out an old voice, "It's not we who broke the agreement. It was your people who killed my kin first!
That woman must die! She will be eaten by my children to make up for her sins!"
"Dream on! Even though I hate that woman to the core, she's still a professor at Hogwarts. Her life and death aren't for you eight - legged freaks to decide!"
Snape held his wand in his hand, and the 'venom' spewing from his mouth was as sharp as ever. "If you don't get out of the way, I'll blow up this maze and bury you all here!"
Snape's tough response silenced Aragog and caused a stir in the Acromantula colony.
Many Acromantulas' eight eyes glinted with a fierce light simultaneously, eager to devour Snape.
But they didn't put their thoughts into action after all.
"Creak... Creak creak..."
After a moment of silence, Aragog started communicating with its rebellious descendants in the Acromantula language.
It still preferred to swallow this insult in order to ensure that its offspring could eat human flesh later.
The Acromantulas also 'creaked' and communicated with each other for a while, reluctantly accepting the old ancestor's proposal.
Snape had grown impatient. He sent his Patronus to lead the way and directly broke into the corridor where Eris was. He cast a spell and blew up the spider - silk wall blocking the way outside.
There he saw Eris, extremely pale and haggard with black lines spreading up her neck, lying on the ground with her left leg bleeding profusely, retching and struggling yet still managing to stay conscious.
