When Ryan returned to the dorm, everyone in the dorm was asleep, except for Spotted pretending to be asleep. However, Ryan felt that it didn't matter if Spotted knew about his night tour, after all, Gryffindor students, there was nothing strange about night tours.

But because Banban was there, Ryan didn't dare to go to the Wanjie grocery store at this time. It wasn't until the next afternoon, after class, that I took the opportunity to hide in a bathroom and enter the Wanjie grocery store.

As soon as he entered the grocery store, Ryan saw that the dementors were tied up in a ball with much lighter black smoke than they had been when they had been thrown in yesterday, and they also looked weak, not at all as lively as they had been when they were caught yesterday.

I have to say that this net soaked in runic water and rooster blood and made of cotton thread enchanted in advance is really quite restrained by dark creatures, and if you leave it alone, it is estimated that the Dementors may disappear completely in a few days.

Thinking of this, Ryan quickly assembled the portable portable altar, and hung a charm around the altar with this cotton thread. He shook a Dementor into the altar from the net.

After the Dementors entered the altar, a milky white protective layer quickly rose around the altar, after which some runes held the Dementors motionless in mid-air.

Everything is ready to go. Ryan first used life magic to try to detect the Dementor's condition, but the flying runes vanished after a puff of gray smoke emitted from the cloak that touched it, apparently hindering Ryan's magic.

Its cloak actually had anti-magic detection capabilities, and Ryan, who saw this scene, took out the obsidian honor guard knife that he had harvested in the pyramid temple from the counter next to him, which could act on spirits.

According to a fanbook I've read in my previous life, the Dementor's cloak may have been a very valuable magical ingredient, and from what I've seen so far, it's very likely.

So the first thing Ryan did after waving his wand to summon his hairy crab patronus and use his mind to protect the soul was to cut off the Dementor's cloak with an obsidian knife.

Unfortunately, the cloak turned into a puff of black smoke not far from the Dementor, and at the same time, another section of the cloak grew on the Dementor's body to make up for the missing part.

This should be the same as the clothes worn by the Shapeshifters when they transform, they are all part of their body. Thinking of this, Ryan suddenly found that it meant that when he was performing a mission to transform, the demon girl was-

Okay, stop, now the focus is on thinking about the Dementors. Since the cloak and the Dementor are one, it means that the Dementor is an energy creature, and the energy of most energy creatures can be depleted. Thinking of this, Ryan commanded the hairy crab patronus to step forward and cut off the dementor's cloak and erase it with the energy on his body.

As the Patronus continued to erase the Dementors' robes, the Dementors grew weaker. Eventually, it was no longer able to condense its robes, revealing a blue-gray rotting body.

"It's awful. Ryan grumbled as he swung his obsidian knife and tried to get some samples from the Dementors.

The Blade feels significant resistance when slicing into the Dementor's body, suggesting that the Dementor is not a spirit creature, but has a body of its own. The process of cutting the samples went smoothly, but unfortunately, like the cloak, all the cut samples quickly turned into black smoke. Later, the Dementors can be seen slowly growing back the severed parts.

However, perhaps because of the previous consumption, Ryan felt that the Dementors had become more unreal after growing the severed parts. This was also proven by the obsidian knife cutting later, if it used to feel like cutting a barbecue, now it feels like cutting a pile of cotton wool.

"Now it's just a matter of looking at it as a whole. Ryan sighed and began to chant life magic, and soon the runes were pouring into the Dementors again. Without the cloak in the way, this time the runes successfully submerged into the Dementor's body and began to transmit various data to Ryan.

"Not alive, but not dead. It's such a strange creature. Ryan frowned as he took in the data from the Dementors. But beyond this conclusion, there seems to be a strange mist on the Dementors' bodies that is preventing Ryan from obtaining further information.

"That's the only way to try. Ryan thought about taking out a mud pill from the space bag on his waist, which was made by sweeping the dust off the tombstone in Uncle Jiu's world, and was generally used to communicate yin and yang. After discovering that the Dementors were somewhere between yin and yang, he came up with a new solution.

Ryan used the rune to dissolve the mud pill, then pulled out a brush and dipped it in muddy water, ready to draw a spell on the Dementor. To be on the safe side, Ryan first drew several runes on his right arm with his own magic ink.

As expected, as soon as his hand reached the barrier, he saw the Dementors attack. A powerful suction force emanated from its mouth, as if it was about to pull Ryan's soul down its arm.

At this time, the rune on his right arm suddenly emitted a golden light, and the dementor was pinned in place at once.

"Alright, let me see what secrets you're hiding. Ryan muttered as he began to draw runes on the Dementors.

After drawing a dozen runes, Ryan heard a sound similar to breaking glass coming from the Dementor's body, and then a large amount of disorganized information with black smoke passed through the previous runes into Ryan's sea of knowledge.

"Soul attack, is this a desperate gamble?" Ryan calmly turned his merit power into a barrier to block the black mist, and at the same time filtered out the information mixed inside.

With this last wave of attacks, the Dementor's body was completely depleted, and the lamp turned into black smoke. Ryan didn't care about the situation on the altar, but closed his eyes and began to sort out the harvest he had just made.

Ryan opened his eyes after more than half an hour, and he finally figured out what it was like to be a Dementor.

This kind of monster is actually composed of soul energy and various negative emotions scattered between heaven and earth, and the dementors rely on negative emotions to glue these different sources of soul energy together to form a monster between life and death.

The reason why Dementors want to absorb the positive emotions of humans is because mere negative emotions can only keep them alive as instinctually as beasts. And only after absorbing enough positive emotions as a balance can the Dementors' consciousness evolve greatly.

In addition to positive emotions, Dementors also need the souls of intelligent beings to strengthen their souls and evolve their souls, but simply absorbing the free soul energy of nature is too slow and takes a lot of time to evolve. That's why the Dementors are eager to drop their hoods and suck their souls intact.

Only after satisfying these two points of evolution can the Dementors truly complete their evolution into intelligent life.

Dementors who become sapient beings automatically become the leader of the pack. According to the information read from this Dementor, there were more than a dozen leaders in Azkaban, and there were two leaders among the Dementors who came to Hogwarts this time.

"Today is a long day of insight, and I have come to know a life form that I have never seen before. Ryan thought as he sat in his chair behind the counter.
