"Interesting techniques?" Klein asked curiously. Old Neil chuckled and said: "I'll go and inspect the weapons, materials, and library. You use the two cups on the table to make two cups of coffee. Put something bad in one of the cups. What exactly it is is up to you to decide, use your imagination. The only requirement is that you shouldn't waste too much coffee powder. That's the coffee I hand-ground with the special coffee beans from the plateau!" "OK." Klein, although not fully understanding what Old Neil wanted to do, still happily agreed. Watching him take out the copper key and open the iron door of the weapons room, hearing the long footsteps echoing inside, he slowly arranged the cups, confirmed that there was hot water in the pot. Removing the lid of the silver tin can, Klein used the shiny little spoon to sprinkle a spoonful of richly scented coffee powder into each cup separately, then poured hot water, and stirred skillfully. — As a time traveler from an era with abundant resources, he wasn't unfamiliar with coffee. After doing all this, Klein thought for a moment, sat down, lifted his right leg, and used his fingers to pinch some dirt from the sole of his boots and put it into the left cup. Then, he carefully did the stirring again until the two cups of coffee had almost no difference in appearance and aroma. After a few minutes, Old Neil swung his key chain and walked out of the weapons room, slamming the iron door shut. "Done." His dim red eyes turned slowly, looking at Klein across the table. "OK." Klein nodded in reply. Old Neil smiled and began to untie the silver chain around his wrist, sitting down. His expression quickly became calm. His left hand held the chain out, letting it hang vertically on the coffee cup on his right, the pure white crystal was just a little bit away from getting stained by the liquid. In a relaxing tranquility, the white crystal inexplicably began to move slightly, doing a small counterclockwise rotation with the silver chain. "This cup has the bad things put in it." Old Neil said in an affirmative tone. Before Klein could confirm, he folded up the silver chain, picked up the other cup of coffee, and took a sip: "Do you like bitter coffee? I'm used to one spoon of sugar and one spoon of milk." Klein didn't respond. With great interest, he asked: "Your divination results are very accurate. Is it based on that pure white crystal? It's the white crystal, right?" "This is the pendulum method in divination, also known as the spirit pendulum method. It relies on the connection between the spirit body of the crystal and the spirit world, the stars, and the use of some natural materials and spiritual communication, such as crystals, gemstones, and special metals, to predict the good or bad of things... Let's go back to those two cups of coffee. Counterclockwise movement means bad, clockwise means good, no movement means neither good nor bad. You can write the events on a piece of paper, pay attention, it's not a problem. Old Neil put down the coffee cup in his hand, explained in detail. Klein seemed to be thinking: "That means don't use interrogative sentences?" "Yes, don't use 'Whoever is willing to be my fiancée', use 'Whoever is willing to be my fiancée', write it on the paper, lay it flat on the table, then hold the chain with your non-dominant hand, pay attention, it's your non-dominant hand. At this time, straighten your arm, adjust the length of the chain, let the crystal just hang directly above the paper, almost touching the events we wrote, then close your eyes and silently repeat that sentence seven times in your mind. After finishing, open your eyes, see if the spirit pendulum is moving, if not, close your eyes again, repeat the previous process until there is a movement." Klein nodded slightly: "Counterclockwise 'No', clockwise 'Yes'?" "It can also be interpreted as not smooth and smooth." Old Neil corrected, teaching Klein the other uses and details of the spirit pendulum divination. Klein thought about it several times and realized that this was a very practical divination technique. For example, when in an unfamiliar environment, one could use it to quickly determine whether the food was poisonous, without needing to acquire additional skills such as "Wilderness Biology". When However, this form of divination is too simple and only yields two or three possible answers, making it impossible to conduct in-depth exploration and interpretation. For instance, although certain things are harmful to themselves, after certain processing, they can become very beneficial. For example, some ingredients may indeed cause harm to the human body, but it's not severe. In a situation where one is on the verge of starving, having a bite actually doesn't pose too much of a problem. None of these can be judged using the pendulum method. "I need to save money as soon as possible to buy crystals or pure silver to make a pendulum..." Klein sighed. Old Neil looked at him in surprise: "You can apply directly. This belongs to extraordinary individuals. Especially for us, this type of auxiliary-oriented extraordinary individuals, the standard equipment in our arsenal still has a yellow crystal and a piece of pure silver pendulum." "But I'm not yet a formal member of the team..." Klein's heart skipped a beat and he was somewhat hesitant. Old Neil chuckled lightly: "For extraordinary individuals, whether they are formal members or not, since there's no salary increase, then some kind of certain convenience must be provided in other aspects." "Perhaps 'benefits' is a more appropriate term. I'll apply to the captain right away!" Klein clenched his fist in his mind and made a decision. Without trying, how could one know if the captain would agree? "OK," Old Neil smiled and said, "Let's start the formal 'mysticism course'. One of its basics is called 'symbolism'. Do you know what 'symbolism' is?" Klein recalled the fragmented words he had heard before and what he had seen and heard in the astral realm and above the gray fog, and deliberated before saying: "Whether in the astral realm, the illusory starry sky, or those unknown domains, they are all outside our sensory world. The information obtained through ears, noses, and eyes cannot accurately describe them. What we get are intangible intuitive inspirations and experiences, which manifest as abstract symbols and images representing different things and meanings. These symbols respectively represent different things and meanings." "Very accurate. You truly are a 'diviner'." Old Neil nodded solemnly and said, "Only by mastering the ability to interpret symbols can one truly enter the door of mysticism. Well, the patterns on the Tarot cards, each element on the pattern, is a symbol, an artificially defined symbol, to help us understand and interpret the original 'inspiration'." He took out a piece of paper and picked up the nearby pen, drawing a short arc. Immediately after, he added several vertical lines beneath the arc and looked up at Klein, saying: "Do you know what this symbol represents?" Klein looked and looked again, and after a while, hesitantly said: "Eyelashes?" "..." Old Neil let out a breath and said, "This is the symbol of the Harvest Constellation, this is the Thunder Constellation, and this is the White Frost Constellation..." He casually drew several more symbolic signs. Klein, while memorizing, couldn't help but speak: "These constellation names are truly, truly very simple and plain, yes, plain!" So rustic and so primitive... Old Neil smiled and said: "Back then, Emperor Rosser also thought so. He had always intended to change the constellation names to something like *** Constellation, Crab Constellation, Scorpion Constellation. Unfortunately, he still couldn't resist the power of tradition. At least the ancient names of these constellations and the dates they represent can guide farming and harvest." "I have to say, Emperor Rosser was a person with ideas." Klein didn't know how to tease. Well, Emperor Rosser must have been a decent person in life... Old Neil couldn't understand Klein's humor and continued to explain various basic symbolic signs, such as those of various constellations, such as the Sun, Red Moon, Brown Star, Red Star and Blue Star. While talking about these, he also interspersed teaching the drawing method and precautions of the divination astrological chart, the making and materials of the crystal ball, and the selection of incantations. Klein felt as if he was overwhelmed by the information. If it weren't for him discovering that the "Diviner" potion slightly enhanced his memory, he would have made Old Neil stop long ago, to facilitate his own digestion of the acquired knowledge. "Today's 'Mysticism Course' is over. You should think it over on your own, and if you have any questions, you can come to me." Old Neil took out a golden pocket watch, snapped it open and glanced at it, "Don't forget to read the historical materials I prepared for you. To be honest, seeing them makes me feel afraid." "Okay." Klein took the drafts with the symbols written by Old Neil, quickly reviewed the mysterious knowledge he had learned today to avoid obvious forgetting. Old Neil took another sip of the freshly brewed coffee and said: "Only relying on memory is not enough. One must use it frequently so that the knowledge can become your instinct. Also, meditation must be done every day. Only by practicing more and using it more can you truly master the power of the potion and uncover its hidden mysteries, eliminating the negative effects." When he mentioned this, Klein remembered the performance and the divination club, tentatively saying: "My potion ability is related to divination. It's not enough to practice alone. One must come into contact with a large number of people, give them divinations, and then quickly master it. I plan to have extra money, then join the 'Divination Club', the one on Holles Street in the North District, to become a true 'Diviner'." This matter will definitely not go unnoticed by the night watchmen. It's better to lay the groundwork in advance. "Your idea is similar to Daria's. She has always said she wants to be a true 'Medium'. Old Neil shook his head and smiled, "But why wait until you have extra money to do this? You can write an application to Dunne to get the approval of the expenses!" "Organizations like the 'Divination Club' may have members who have joined cults or evil organizations. As a civilian staff member of the night watch team, a standard exceptionalist, joining them for monitoring is necessary for the job. It's for the sake of the job! We usually conduct regular inspections of these places, but due to insufficient manpower, it's difficult to follow up for a long time. Now it's up to you to handle it." And this kind of operation? Looking at Old Neil's serious expression, Klein was simply stunned. This is openly finding reasons to reimburse expenses for personal matters! I have absolutely no idea about such things... I'm just a keyboard powerhouse... "You want to use your own money to do this?" Old Neil saw this and added with a smile. Klein immediately shook his head and replied firmly: "I'll report to the captain right away!" Old Neil nodded in satisfaction and looked at the cup of coffee that hadn't been spilled yet, with bad things in it, saying: "What exactly did you put in there?" Klein smiled awkwardly: "Well, it was just a little bit of mud from the sole of a boot. Its color was similar to your coffee powder, pretty much the same." Old Neil was stunned for a moment, then suddenly pressed his hand against his mouth and shouted in a low voice: "Take it out and throw it away right now!"
