All things are three at Hogwarts

The monster's arm actually grew back again, as if it had never been injured.

"Fire is raging." Three magic spells hit the monster at the same time, and the fire engulfed it instantly.

The monster made a miserable cry, and kept slapping its hands on its body.

The flames gradually extinguished, the monster's gorgeous clothes were burned away, and its originally gray skin turned into large areas of burnt black.

Allen keenly discovered that the blackened area on the monster's body did not heal. That means the flames were effective!

The monster suddenly made another surprising move, roaring and digging into the blackened flesh of its body with its hands.

Allen and the others saw that after he dug out the blackened flesh, the remaining parts began to heal on their own.

"I know, it's a troll!" Hermione clapped her hands excitedly.

"If a troll loses a limb or part of its body, it can grow back. If the broken limb is placed on the stump, it can be reconnected immediately. Moreover, fire and strong acid can cause normal damage to the troll and inhibit regeneration. ." Hermione said quickly.

"Hermione is right, but you need to use more powerful flames." Allen also thought of the origin of the monster, and he was already thinking about countermeasures.

The troll had almost recovered and pounced on Allen without hesitation. Frantically grabbing at Allen who was closest to it.

Allen cast a blasting spell, which slightly blocked the speed of the troll's attack. He signaled Hermione and Luna to quickly evacuate outside.

Hermione and Luna followed Allen's instructions and ran outside quickly.

While shielding the two of them from leaving, Allen quickly waved his wand and used the Iron Armor Spell to block the troll.

At the corner that was about to leave, the troll suddenly extended its claws and rushed over, waving desperately.

While Allen was constantly defending, he also had to cover the two women's retreat. When he wasn't careful, the troll's claws reached out.

In order for Hermione and Luna behind him not to be hurt, Allen bit the bullet and turned slightly sideways to avoid the fatal blow.

The troll's claws fell on Allen's arm, scratching Allen's clothes and leaving deep visible scars on his arm.

Blood flowed out of Allen's arm instantly, staining the sleeve near the wound red.

"Alan!" Hermione exclaimed, and Luna's big pale silver eyes looked at Alan's wounds with concern.

"I'm fine, please leave quickly." Allen gritted his teeth, ignoring the injuries on his arms, and urged the two of them to leave quickly.

After leaving the room, Hermione and Luna quickly hid away according to Alan's instructions. Allen attracted the troll's full attention, and the troll chased after him.

Ahead was the deep pit where Allen had fallen. Without losing any momentum, Allen ran straight towards the pit and jumped in without hesitation.

The troll, which had lost its mind, also jumped down staggeringly.

However, before Allen jumped, he had quickly checked the landing position.

As soon as he landed on the ground, he quickly transformed into a phoenix and escaped from the pit trap, returning to the ground.

And the troll, because of his tall and huge body, fell and was impaled by those sharp thorns.

While the troll was struggling, a rolling and rushing sound suddenly came from above him. The raging flames came straight towards the troll, devouring him instantly, turning everything the tongue of fire touched into ashes.

Amid the deafening roar of the flames, Allen healed his wounds, and the three of them continued on in the heat.

Before leaving, Allen returned to the secret room with the sarcophagus again, collected the minced meat scattered by the trolls on the ground in the secret room, and put it into the storage grid.

"Alan, why did you..." Hermione looked at Alan collecting those extremely disgusting gray and black minced meats and found it difficult to understand.

"Now, the troll is almost extinct. Don't you think its ability to heal and regenerate is worth studying? Although it is an undead creature, there is definitely a difference from a living troll, but it still has great reference value. ." Allen had his own considerations.

In addition to the flesh and blood of the troll, in the sarcophagus, Allen found a refined dagger, which may have been used by the troll during his lifetime. Obviously, the troll who turned into an undead creature preferred to use claws to attack.

The jewelry in the sarcophagus is also of considerable value: including an exquisite silver ring, a hollow gold necklace and two silver armbands engraved with dragons.

There are also 220 ancient silver coins and 50 ancient gold coins hidden in the sarcophagus, as well as a dark brown sheepskin notebook.

Allen directly picked up the notebook and flipped through it quickly.

It turns out that this troll was originally a human wizard who belonged to the Dragon Worship Cult. He committed an unforgivable mistake and was buried alive here.

However, he was not willing to end his life, so he used the forbidden spells of the Dragon Worship Cult to capture a large number of trolls. By studying them, he recovered the ancient ancestor troll blood contained in the blood of these trolls and regenerated them. The part that wants to transform itself from a human wizard into a troll wizard is imprisoned alive in the tomb.

Perhaps there was an error during the casting process. Compared with the ordinary troll, the troll he turned into appeared weaker and moved slower.

At the same time, he still retains the customary fighting style of the Dragon Priest. But in fact, because he is very weak, he cannot tear his opponent into pieces as easily as an ordinary troll.

As time passed, his mind gradually became blurred and he gradually became crazy. He sealed himself in the sarcophagus and let himself fall asleep.

Until someone opens the sarcophagus, he will wake up again.

He thought well, but when Allen opened the sarcophagus again, he had lost all his mind and life over the long years, and completely became a troll undead creature.

After closing the notebook and packing up the belongings obtained in the sarcophagus, Allen put the eternal fire on the wall into the storage compartment before leaving.

Next, they returned to the rotunda at the entrance of the castle and walked in another direction.

The room I explored again was basically empty except for some gravel on the ground.

In this small room away from outside interference, the three of them took out some water and food to replenish their strength and take a rest.

"We didn't encounter any werewolves on that road just now. It seems that they entered through this road before. It may be very dangerous next, and we must be more vigilant." Allen solemnly reminded.

Hermione and Luna's expressions also became serious. Their previous experiences revealed the mystery and danger of this underground castle. Coupled with the werewolves who didn't know where they were hiding, it was really dangerous and they had to be vigilant.
