Ted chased in the general direction of the red fireworks while casting Expeditious Retreat on himself.
This was a DND spell, somewhat similar to the Sliding Charm.
The Sliding Charm turned roads or stairs into slippery ice, while Expeditious Retreat made the soles of one's feet function like ice skates.
With the slightest movement, he could glide a great distance over ordinary ground. It required little effort and was incredibly fast.
At the same time, to obtain an accurate location, Ted used Locate Creature.
This was also DND magic. It could reveal the precise location of a creature he was familiar with or had prepared for in advance.
It took Ted less than five minutes to reach the general area.
From far away, he heard a chaotic racket: Malfoy shouting, Hagrid roaring, and several unfamiliar voices casting spells.
Spells struck the tree trunks with dull thuds. There seemed to be three or four opponents!
Professor Quirrell had actually found helpers?
Impossible! Given Voldemort's pride and suspicion, he could never contact any of his former followers in his current state.
Then who was attacking Hagrid and the others?
When Hagrid was young, Voldemort had framed him for keeping an Eight-Eyed Spider in the castle, getting him expelled and his wand snapped.
However, the Elder Wand wielded by Dumbledore could repair wands, so he had secretly repaired Hagrid's wand.
The umbrella Hagrid often carried with him was his wand in disguise.
But Hagrid's spellcasting was merely average at best. He was not skilled at it.
Meanwhile, there were three or four adult wizards on the other side. Ted did not recognize most of their spells, but judging by their destructive power, they were basically all Dark Magic.
Hagrid had Malfoy and the other two burdens to protect, so he was completely outmatched.
