Zuo Mo looked at the various spiritual herbs and strange objects placed in front of him with some trepidation. For example, three incense sticks made from the powder of the Heavenly Yao's whiskers after they had been burned, a small bottle of Ku Cui's demonic blood, and the musk of the Weasel Demon that reeked of a pungent smell...

  These were all bought by him according to Pu Yao's instructions, and he almost ran through the entire Dong Fu, even specially finding He Rong to make up for it. These strange things are extremely expensive, and one thousand third-grade crystal stones were spent in an instant. This time, Pu Yao was unusually generous and took out the crystal stones on his own initiative.

  These strange things are all parts of the body of a demon. The corpse of a demon killed by a demon hunter will be quickly dissected into various useful parts in the hands of a skilled butcher. The demon's body is rich in spiritual energy and has many mysterious places, so it is widely used in alchemy and equipment refining. The internal organs and flesh of the demon can be used to make elixirs, the skin of the demon is mostly extremely tough and is an excellent material for making spiritual armor, and their claws and teeth are made into flying swords that are also top-notch.

  For thousands of years, the activities of demon hunters have been thriving, driven more by interests than hatred.

  However, the risk of hunting demons is too great and the gain is not much, so raising spiritual beasts becomes popular. The qualifications of spiritual beasts cannot be compared with those demons, and the quality of the materials obtained after dissecting them is mostly not high, but they have a large number and low cost. Even a small sect like Wu Kong Jian Men has a special breeding room, which shows how common breeding is.

  The Pu Yao has high requirements for these materials, they must come from the demon world and not from spiritual beasts. This is also why the price is so expensive, any material that has a connection to the demon world is not cheap.

  But...

  Zuo Mo looked at the strange and eerie objects on the table, his heart racing. He felt as if an evil ritual was about to take place here, and these strange, living flesh and blood were the offerings. Even with his usual research on array techniques and such, he had never seen anything so terrifying and ominous.

  "There's nothing good, only barely enough." The Pú Yāo said somewhat helplessly: "These things are just barely sufficient to refine into the lowest level magic seals."

  "What's a demon mark?" Zuo Mo suppressed the fear in his heart and asked.

  "It's a hassle to even mention it." The Pú Yāo picked up various materials, inspecting them as he spoke: "You can think of it as a kind of talismanic array, an innate talismanic array. Flesh and blood, fur and skin, essence and energy, all forming the array. Hmph, cultivators always want to decipher the subtleties within, but the mysteries contained here aren't so easily cracked."

  "What are you going to do now?"

  "Don't be too stupid, you're asking me such a simple question?" Pu Yao looked at Zuo Mo's eyes as if looking at an idiot: "Of course, I'll make a magic seal for you."

  "Make a mark? Can Mo make one? Didn't you say no one could decipher it?" Zuo Mo was shocked.

  "They can't, doesn't mean I can't." Baoyou snorted coldly and proudly said: "In the past..." He suddenly realized something and shut his mouth.

  Pu Yao didn't want to say, Zuo Mo was curious but didn't ask either, pointing at another pile of spiritual grass and asking: "What about these spiritual grasses? Are they also used for tattoos?" The materials on the table were clearly divided into two piles, one pile of spiritual grass and one pile of yao demon's dirty organs.

  "That's another thing I've added for you." The púyāo chuckled: "A very interesting thing."

  "Oh." Zuo Mo nodded as if he understood and didn't understand at the same time. Suddenly, he felt his eyelids getting heavier and heavier, very sleepy...

  "Don't forget!"

  "Even in death, I will never forget!"

  He was dreaming again. Zuo Mo let out a soft sigh, and he became like a calm onlooker, watching his own dreamscape. He knew that no matter what he said, it would be useless, no one would answer him, or perhaps this dreamscape just wanted to throw a question at him.

  He is waiting for her to wake up.

  When he opened his eyes, he saw Pu Yao's handsome and charming face.

  "Welcome back!" The Pú Yāo smiled with some profound meaning.

  Zuo Mo sat up, and with this movement, he suddenly felt an intense pain. Every part of his body seemed to have a wound, and he smelled the thick smell of blood in the air.

  "Did it work?" Zuo Mo was startled by his own voice and found that he had completely lost it.

  "Success? I'm too ashamed to use those two noble words for this trash. But there's no other way, who made you so poor, it's still my reward, you have to return me this crystal as soon as possible." The Peony Demon said with a hint of mockery.

  On the left, Mo Yue's painful expression was met with Pu Yao's delighted appearance: "I've added a simple magic seal on you. Hmm, I discovered this pattern on a Bronze Rhinoceros Demon, it's very primitive and simple, it can automatically absorb the surrounding spiritual energy to strengthen your body. Your body will turn copper-colored, which is just right for your cultivation of the 'Vajra Minor Precepts', with a slight disguise, no one will be able to notice."

  Zuo Mo struggled to sit up at this time, and he was suddenly startled. Two thick red lines extended from the center of his palms along his arms to his chest, intersecting on his chest, then separating downwards, following the two legs all the way to the soles of his feet. The intersection point on his chest seemed like a knot tied by the two red lines.

  Seeing Zuo's concern, Pu You said carelessly: "Don't worry, in two more days, these patterns will merge into your flesh and blood. Even if others cultivate the Heavenly Eye or similar techniques, they won't be able to see them."

  Zuo Mo couldn't help but let out a sigh of relief. If he were to go out with such frightening tattoos, his life wouldn't be easy.

  "This spell is quite simple, of course, you can't expect it to have a great effect." The Pú Yāo said irresponsibly: "It's because you're too poor, one penny one penny goods, no crystal, naturally there's nothing good."

  Zuo Mo felt a faint pain in his brow and involuntarily reached out to touch it. As soon as his hand touched his forehead, his fingers seemed to come into contact with something foreign.

  "What is this thing?" Zu Mo suddenly remembered that Pu Yao had added something extra for him.

  "Heh heh, a fake core." The Pú Yāo was very pleased: "Although this thing can't compare to a real core, for you, it's more than enough."

  Youmo knew that demons have demon cores, and devils have devil pellets. This is an important basis for judging demons and devils. Although cultivators also form golden elixirs, these golden elixirs are formed by the gathering of spiritual energy and are not physical objects, which automatically disperse after death. However, demon cores and devil pellets are physical objects that grow inside the body and are extremely important raw materials.

  "Youxian?" Zuo Mo asked with some trepidation: "What does it do?"

  "You'll know if you try," said Pu Yao.

  Zuo Mo didn't say a word and hurriedly activated Embryonic Breathing Spiritual Cultivation.

  This rotation, suddenly felt the difference. The surrounding spiritual energy, competed to gather towards oneself. All over his body's pores naturally opened up, and the spiritual energy effortlessly drilled into his body, his flesh and blood was like a magical filter screen, lightly and easily filtering out the impurities in the spiritual energy, transforming into starlight spots, merging into his flesh, blood, and bones.

  Zuo Mo was slightly stunned, it really was as Pu Yao had said - as easy as breathing. There wasn't any of the usual blockages, those ling energies seemed extremely close to him.

  He was overjoyed!

  With the magic thread, his cultivation speed will increase several times.

  He thought of the demon core mentioned by Pu Yao, although he didn't know what it looked like, but it was definitely related to his divine consciousness. Sure enough, he soon found the demon core at his brow point, a blood-red crystal, somewhat similar to the blood crystals on Pu Yao's earlobe, but in terms of luster and purity, it was far inferior.

  What made Zuo Mo feel even more astonished was that with an additional piece of Netherworld's core, his spiritual body underwent a huge transformation.

  His divine sense was like a cloud of fog before, but now it's like a single-celled jellyfish with many long tentacles, and the demon core is tightly wrapped in the center by his divine sense. These long divine sense tentacles, centered on Mo Ye, floated around him, and everything around him was clearly reflected in his mind. Since cultivating his divine sense, his six senses had become much sharper, and after gaining the demon core, this sharpness had increased several times over.

  He thought for a moment, and those spiritual senses touched his hands extremely agilely flying around him at will.

  Zuo Mo had always been anxious and finally couldn't hide his wild joy, if nothing else was said, with alchemy, his success rate would definitely increase greatly.

  These two benefits are worth it, even if some costs have to be paid!

  With this demon mark and demon core, his cultivation speed will increase several times.

  Just as Zuo Mo was overjoyed, Pu Yao suddenly said, "Don't be too happy yet. This magic seal and demon core, I haven't done for anyone else either. Who knows what side effects there will be? You're on your own. You need to study the talisman array well. Even if you absorb spiritual energy quickly, if you can't store it, it's all for nothing."

  Zuo Mo gradually calmed down from his extreme excitement.

  What Pu Yao said is right. The efficiency of absorbing spiritual energy has increased several times compared to before, but if the problem of storing spiritual energy isn't solved, it's indeed useless.

  "Learn the formation." Pu Yao said seriously, "For now, you only need to learn the formation."

  "Is it just about learning Fu Zhen?" Zu Mo was somewhat perplexed, feeling that Pu Yao's words were too absolute.

  "That's right." The Pú Yāo explained: "Whether it's alchemy or sword techniques, the essence is all about talismans. This is something you have to learn on your own, as a cultivator's talismans are too complex and cumbersome. Moreover, they're completely different from our understanding as demons, many things we find hard to comprehend."

  "You can't understand it either?" Zuo Mo was a bit skeptical. Although he thought that the potted spirit was just a stupid spirit, in terms of cultivation, Zuo Mo believed that one potted spirit could surpass him by a hundred times. If even the potted spirit couldn't understand something, how could he possibly understand?

  Pu Yao's expression was rarely serious, and he said a sentence that Zuo Mo couldn't understand: "It has nothing to do with the law, but everything to do with faith."

  Although he didn't understand, Zuo Mo felt that Pu Yao's words were extremely serious, probably the most serious thing Pu Yao had said so far. He secretly memorized this sentence.

  "What about alchemy? What about swordsmanship?" Zuo Mo was still somewhat hesitant.

  Pu Yao finally got annoyed with Zuo Mo: "Stupid, they are also formation arrays, don't be deceived by appearances. Anyway, just focus on studying formation arrays."

  "I don't have Jade Ann..." Zuo Mo said weakly.

  The pao yao irresponsibly spread out his hands: "There's nothing I can do about this either."

  Suddenly, Pu Yao was seen smiling gloomily, and Zuo Mo couldn't help but feel a bad premonition in his heart. Sure enough, he then heard Pu Yao say leisurely, "Alright, I think it's necessary for us to discuss the issue of my reward this time."
