Just after a day's lessons, Xiwen went to the Room of Requirement to complete the day's homework.

Meanwhile, another young wizard, Xiwen, was in the dungeon room, reading a tattered notepad that he had received from the dark-eyed demon god servant Sukarno.

The ghost Xiwen was floating beside him gesturing with his hands, and occasionally different colors of light appeared between his hands from time to time, trying to deduce and analyze the method of applying spells.

However, the dungeon room and the room of requirement are also connected by Xiwen with a dimensional door, and you can see the picture of two Xiwen in the same frame if you change the angle slightly.

Helena looked at the several Xiwen in front of her, and felt a little at a loss.

She secretly glanced at each Xiwen on the side, and concluded that only Xiwen, who was doing her homework, was the most absent-minded, so she was easily disturbed by herself, so she floated through the dimensional door to the Room of Requirement.

"I remember you had a note on the use of a time turner, and it said something like 'don't meet your old self', right? Is it really appropriate for you to act like this......" Helena asked Xiwen who was doing her homework a little helplessly.

She beckoned as she spoke, and the pledges and precautions that Xiwen had thrown in the dungeon room floated straight through the golden circle of light.

Helena took the materials, pointed to a piece of parchment, and said to Xiwen, "You haven't read this how to use a time converter, have you?" You don't want to think about what to do if something really goes wrong. ”

"You've promised to teach me the spells of Kama Taj, and I won't allow you to be in danger because of your own negligence, and then break your promise to me!"

Xiwen stopped writing and looked up at Helena, but suddenly laughed happily.

"I'll just say it if I'm worried! What excuses? He laughs.

Helena blushed a little, but immediately said stiffly, "I'm not worried about you little wizard, I'm just afraid that your indiscriminate use of the time turner here will affect your soul body!" ”

Xiwen chuckled, and immediately caused the soul body to stop the work of deducing spells, and floated through the dimensional door into the Room of Requirement.

Helena was confronting the little wizard Xiwen at this time, and she was unaware that the ghost Xiwen was holding her waist behind her, which made her immediately blush, completely unconfident.

"Thank you for your concern." Ghost Xiwen put his arm around Helena's waist and didn't want to let go, smiling and whispering in her ear.

In fact, every time Xiwen traveled through time, because he didn't bring his soul body with him, he couldn't immediately feel the perception and thoughts of his soul body under the barrier of time power.

For example, now, the little wizard Xiwen who is doing his homework in the Bing Room can connect with the ghost Xiwen instantly, but the little wizard Xiwen who is reading Sukarno's notepad does not receive any thoughts from the ghost Xiwen.

Therefore, even if the future and the past are the same person, even if they have been in the same place, the effect of time travel has always existed.

In this way, the five-hour time travel limit is completely reasonable, otherwise even if the time traveler does not feel any discomfort, under the subtle influence of the power of time, it will still cause a strong backlash to his body after all.

Thinking of this, Xiwen was no longer conceited about his understanding of the power of time in Kama Taj, reached out and took the parchment of "Principles for the Use of Time Turners" in Helena's hand, and carefully read the principles listed on it-

"The principles of using a time converter: 1. Use it only to solve the most trivial time management problems, and never try to solve something bigger or more important with it."

"2. Don't let anyone know, don't let others see."

"3. Time travel should be controlled within 55 hours."

“4、……”

At the bottom of the page, at the end of a page full of entries is a proverb: "Just as man cannot understand time, he cannot understand what a catastrophe it will bring to mankind if he tries to erase the laws of time." ”

After reading it, Xiwen fell into thought.

This world is actually very contradictory - it is possible to collect time energy, but the need for time travel can only be achieved through a single way of time reversal spell in the time converter.

In addition, wizards also realized the dangers of unrestricted time travel due to the accidents of several experiments, so hundreds of laws were enacted to regulate the use of time converters.

However, researchers at the Ministry of Magic and the Department of Mysteries were not willing to stop their research on time altogether, so they allowed the time turner to be lent to good students at Hogwarts who were both good at learning and learning, so that they could collect time travel data and use samples, so that they could conduct safer research.

But this situation is very dangerous, and not all people who appear to be good at learning will strictly follow the rules. For example, Xiwen himself......

"Well, after reading the principles of using the time converter, is there anything you would like to reflect on?" Helena's voice interrupted Xiwen's thoughts.

The little wizard Xiwen just smiled and didn't say anything, but the ghost Xiwen lowered his head, almost next to Helena's side face and said, "Don't worry, the second principle of use is for those who don't know anything about the time system. ”

"When those people see their future selves, they are likely to think of them as dark wizards impersonating themselves or demagogic evil creatures, which leads to the tragedy of those who are injured or even killed by their past selves."

"I'm different, I've had an understanding of the power of time a long time ago, so I won't have the situation of mistaking my future self or even thinking of myself as a bad person!"

Helena saw that Xiwen leaned her face over, and rubbed the side of her face on his cheek affectionately, and still asked with some concern: "But in the principle of 'not letting others see', you only explained that you don't let your past self see it, but you didn't say why you can let me know about it?" ”

"I don't think I violated this, after all, it says that it is not allowed to be seen by other 'people', and you are just a ghost." Ghost Xiwen laughed casually.

Helena was about to refute, but suddenly she heard a buzzing sound, so she subconsciously turned her head to look in the direction of the dungeon room.

Xiwen also turned his head in surprise, and saw the scimitar leaning on the corner of the wall wrapped in layers of golden magic whips, and it trembled violently very suddenly!

The binding of the magic whip that had been specially made to bind it even loosened slightly, causing it to fall to the ground completely.

"Is this Barrow's knife?" Helena asked.

Xiwen frowned and nodded slightly.

"Did Barrow come out of his locked room and want to summon this knife back?" He guessed suspiciously.

He had previously learned from Helena that the knife was most likely made by Salazar Slytherin from a living snake, and that Barrot had always been the master, and had even become a ghost with him.

So it probably makes sense to have this function of receiving callings.

Naturally, Xiwen didn't want this knife to be taken by that annoying Barrow again, so he directly summoned a Crimson Chain of Setolak, completely binding the scimitar.

"Shall we go to Sir Nicholas and ask Barrow how he is doing?" Helena watched Xiwen's movements and spoke.

"It's fine." With a slight bow, Xiwen opened a dimensional door to the ghost meeting room.

The ghost meeting room has long since been transformed into a mirrored world, which has expanded many times over, and all sorts of sumptuous foods often appear out of thin air from the plates on the four long tables.

Ever since it had been transformed from a conference room into a ghost cafeteria, Grubb the Fat Man had gotten rid of a bad habit of not going to the door of the auditorium to stop the little wizards who were about to go to dinner.

He now stays in the ghost cafeteria all the time every day to "eat", as if he can't get tired of eating and can't eat enough.

As soon as he arrived at the ghost meeting room, Xiwen saw Grubb feasting.

The corners of his mouth twitched and he thought for a long time, and then he barely found a word to describe Grubb, and commented on him: "The ghost who dies for the sake of eating, and treats eating as an obsession, is really ...... Very unique......"

Helena nodded approvingly.

She has been a ghost for nearly a thousand years, and Edmund Grubb, a little fat man, is also the first ghost she has seen who is obsessed with eating.

Grubb had just finished a plate of ghost dishes when he looked up to see Shewin and Helena watching him.

So he floated over excitedly and said loudly, "Mr. Strange, I haven't seen you for a long time!" ”

Shewin smiled at him, and said, "I won't bother you to enjoy your meal, I'm here to find Sir Nicholas, or if the monk is there." ”

"Sir Nicholas has gone to Sir Deleni Podmore of the Headless Hunters, and he's ready to submit his first application for membership for an unknown number of times." Grubb said. "But the Fat Friar is in the castle, and he should be telling stories to the freshmen in the Hufflepuff common room right now."

Sheavin nodded knowingly, and was about to drift to the Hufflepuff common room to find the Fat Friar, but was stopped by Helena.

Helena shook her head at him and said, "The Hufflepuff common room has never been entered by wizards from any other house, and it should not be appropriate for us ghosts who are not Hufflepuffs to go in. ”

"In that case, how do we find the monk?" Xiwen asked.

"Why don't you wait here for a while?" Helena said uncertainly.

"But Barrow's cutlass suddenly appeared in this general situation, and I still want to find out the specific reason as soon as possible." Xiwen frowned slightly and said softly.

At this moment, Grubb suddenly jumped out and said excitedly: "Mr. Strange, I can help you go and call His Excellency the Fat Friar back!" ”

"Is that okay?" Xiwen asked.

"Of course, I'm also a Hufflepuff ghost!" Grubb patted his chest proudly and said to Xiwen.

"Then please, Grub." Xiwen also put his mind at ease and said with a smile.

"No problem, it's my pleasure to do things for Mr. Strange!" Grubb said excitedly.

With that, he immediately floated towards the door of the ghost conference room, the gateway to this mirror space.

However, halfway to the gate, he seemed to remember something again, and quietly turned around and added in a low voice: "If only there were a little more types of meals in the ghost conference room......"

Xiwen nodded with a smile, and then updated all the food he had seen and remembered everywhere in the past two years on the long table in the ghost conference room, and set them up with auto-replenishing spells.

The new dish almost filled all four long tables with plates.

……

A moment later, the fat friar floated into the ghost conference room with Grubb.

As soon as Grubb entered, he noticed that many new delicacies had appeared on the long table, so he thanked Xiwen excitedly, and then rushed to the table to continue his great business of eating.

The fat monk smiled helplessly, and said to Xiwen: "Grubb, this kid is good at everything, but he is too greedy. Especially after you gave the ghost the conditions to eat, it was even more incredible, and you couldn't stop eating there every day! ”

"After all, when there is no such mirror space, he dares to taste those rancid and smoky leftovers of reality, and these are naturally no problem compared to those dishes." Xiwen said with a smile.

"Yes." The Fat Friar nodded approvingly, then asked. "I heard you have something to ask me about this time, Mr. Strange?"

"There's something I want to inquire about." Xiwen nodded. "I wonder how Bloody Barrow is doing?"
