The circle of purple mes was not tall, measuring only about ten centimeters high—an easy step would carry one over it—but those dancing mes seemed like a boundary, thoroughly isting the inside of the circle from the outside.


    "This is a form of protection, and I hope you will remember that no matter what ritual you perform, always take the necessary precautions to avoid unnecessary dangers, especially with spiritualmunication rituals. It is strictly forbidden to proceed without protection," Chen Yu exined the precautions of the ritual to Misumi Mikoto.


    Besides her, Kube Rokuro and the Nakado Department were also listening seriously, as this was a rare opportunity for them to encounter the mysterious and unknown.


    Especially for the Nakado Department, ever since he learned that this spiritualmunication ritual could summon his lover, he listened even more intently, hoping to memorize the ritual so that he could have the ability to summon his lover too.


    "Teacher, why? Could there be some danger in a spiritualmunication ritual?" Misumi Mikoto asked Chen Yu about things she didn''t understand. She clearly knew that pretending to understand in a field she was unfamiliar with could lead to severe consequences.


    "Every ritual is potentially dangerous because there''s always a chance of losing control.


    Although for some rituals, the possibility of going out of control is as likely as you choking to death on drinking water, it''s not nonexistent," Chen Yu joked in a half serious manner before exining earnestly, "Spiritualmunication rituals require summoning andmunicating with spiritual bodies or certain special entities.


    Depending on the level of the ritual, it will have different levels of attractiveness to entities of different levels. Dr. Misumi, you must have heard stories about young girls ying with soul summoning and ending up calling forth evil spirits, right?"


    "Teacher, you can just call me Mikoto," Misumi Mikoto remarked, apparently feeling it was odd for Chen Yu to call her Dr. Misumi, and then she nodded, "That kind of thing is a ssic trope in ghost stories."


    "Yes, that is what could actually happen, especially in the case of spiritualmunication rituals. Without proper protection, it is quite normal to attract evil spirits or even more dangerous and evil entities," Chen Yu said, casting a nce at the Nakado Department, who turned his face away in embarrassment but still listened intently.


    "Why does that happen, Teacher? Is there a problem with the ritual itself?" Curiously, Misumi Mikoto voiced her doubts to Chen Yu and asked with concern, "If it were me alone, how should I protect myself?"


    Chen Yu looked at Misumi Mikoto with approval, picked up the salt and white crystals and white candle prepared by Kyuuzai Ryousen, and exined, "Spiritualmunication rituals inherently use the power of the ritual tomunicate with spiritual bodies. During this process, the ritual generates a strong attraction to spiritual bodies.


    The more advanced the ritual, the stronger the attraction, and the stronger the spiritual bodies that might be attracted, among which evil spirits are a verymon urrence.


    As for your question about how to build defenses, that''s a very good question. The fact that you considered this even though I''m protecting you today shows you have the caution necessary for learning magic. Maintain your reverence for the unknown and the mystical.


    Because the spiritualmunication ritual I am teaching you today is very simple, the method to build defenses is also very simple. Under normal circumstances, just drawing a circle with salt around yourself is usually sufficient.


    For something a bit more advanced and effective, you can use a small dish filled with salt, ce a white candle on top of the salt pile, then set it at the four corners of a room. Additionally, hanging white crystals in corresponding positions can provide very good protection.


    However, you must be careful that if you actually attract an evil spirit, you must immediately stop the ritual. This kind of defense is too rudimentary; once the salt or candle is used up, the protection will be broken. So if you find that you have summoned an evil spirit, you must end the ritual immediately, understand?"


    Misumi Mikoto quickly nodded, while the Nakado Department thought to himself that he needed to buy more salt in the future.


    "Alright, when conducting a spiritualmunication ritual, after you''ve set up the defenses, what you''re going to face next is the ritual itself," Chen Yu said as he drew another circle in the area surrounded by mes, using animal blood prepared by Kyuuzai Ryousen, and exined, "Blood is an excellent medium for rituals.


    It''s used in many spells and rituals, and the more advanced the ritual or spell, the more stringent the blood requirements are. Of course, for the simplest rituals we are conducting today, ordinary animal blood is sufficient, without the need for human blood or live sacrifices.


    Don''t think it''s impossible. In fact, if you really want to conduct a high-level spiritualmunication ritual, preparing a few living people as offerings whenmunicating with certain entities who have peculiar tastes is quite normal. Some entities might even require you to prepare a massacre. Of course, those are not the kind you would want tomunicate with, I presume."


    Misumi Mikoto realized through Chen Yu''s words that magic was not just an interesting and mysterious thing; it was also very dangerous, particrly the necromancy she had chosen to learn, which dealt with the dead.


    "Returning to the ritual itself, in most rituals, the ritual magic circles used are circr, symbolizing the world and truth.


    Especially for Necromancers, it represents the one truth we believe in, the Unity of All Things," Chen Yu finished drawing the magic array, and began to exin the deeper meaning of the magic array to Misumi Mikoto, "Within the circle, we usually use shapes imbued with magical power such as triangles, squares, pentagrams, and hexagrams as part of the magic array.


    Today, to keep it simple, we are using the triangle."


    Having said that, Chen Yu lit candles at the three points of the triangle he had drawn. But clearly, these candles were different from the white candles he had shown to Misumi Mikoto before, and she noticed this because the mes that the three candles burned with were green.


    "These are ritual candles, a special type of ritual material made mainly from materials such as human hair soaked in corpse oil, corpse wax, cat ashes, grave moss, and grave soil.


    The process is quiteplex, and I will provide you with a method for making themter, as it''s something you must master," Chen Yu noted the noticeable disappointment on the Nakado Department''s face when he said this, chuckled, and then purposely added, "Of course, white candles can also be used, but as for the effectiveness... It''s a matter of luck, it could still work if you''re lucky."


    After finishing, Chen Yu recited the summoning spell over thepleted ritual magic circle, and with his incantation, a semi-transparent female figure finally appeared within the magic circle of the ritual.
