"Master? I just injected soul power, not spiritual sense? Zhang was puzzled and held the incense burner horcrux in the palm of his hand and muttered to himself.

"A natural Horcrux needs to be injected with soul power and spiritual sense to recognize the owner, and if someone provides its soul power and feeds it in the stage of the Horcrux in the stage of conception, then once the Horcrux gives birth to the soul spirit, the spirit will remember the taste of the soul power of the person who feeds it, and naturally regard that person as the master." Nuwa's remnant soul explained.

"Master Nuwa, why didn't you say it earlier, I still want to put it back as it is after I use it, if this artifact spirit recognizes me as its master, then the old man Zhong who made this horcrux will not be able to slaughter me when he comes back." Zhang Su complained.

"You don't need to say it earlier? Without this incense burner horcrux, how do you deal with that source heaven crown worm? You only have these Yuantian soul power that you give me, I can continue to pass on my mantle to you, since things have happened, then relax, when the time comes, just explain it well, by the way, don't say anything about the Yuantian soul power. Nuwa's remnant soul comforted.

"To borrow your auspicious words, indeed, without the spirit of this incense burner, it is impossible for me to subdue the Source Heaven Crown Insect, but this excuse is not easy to find, and once this Horcrux recognizes the master, unless my master is dead, otherwise this Horcrux will be of no use to others, and it is inevitable that there will be no indisputable situation." Zhang said.

"This is a good thing, there are very few Horcruxes that can give birth to a real instrument spirit, once there is a spirit in the Horcrux, then this Horcrux has exceeded the level of the high-grade Horcrux, and then if you can maintain and support it well, it is also possible to grow into an ancient Horcrux, not only the ancient Horcrux can be called an ancient Horcrux, all Horcruxes with a strong enough spirit can be called an ancient Horcrux, whether it is an ancient Horcrux or a source of heavenly Horcruxes, it is just a level name, not referring to time, Now your world can barely give birth to ancient horcruxes, and the source heaven horcruxes can no longer be conceived in this heaven and earth realm, not that there are no methods and formulas, but the source heaven soul power in the soul realm is too thin to meet the basic needs of the source heaven horcrux generation. Nuwa explained the hierarchy of Horcruxes.

"So the Source Heaven Soul Jade can't be fully opened because of the lack of Source Heaven Soul Power, right?" Zhang Su asked thoughtfully.

"That's right, using the Source Heaven Horcrux also requires the Source Heaven Soul Power, so even if the Source Heaven Horcrux exists now, few people can use ordinary soul power to urge it." Nuwa's remnant soul nodded in affirmation.

"In other words, as long as there is enough Source Heaven Soul Power or Source Heaven Remnant Soul, the Source Heaven Soul Jade can be completely opened?" Zhang Su seemed to understand something.

"That's true, but in today's world, the source heaven soul power has been thinned to the point of 'nothing', and collecting enough source heaven soul power to completely open the source heaven soul jade is like a fool's dream." Nuwa's remnant soul said.

"Then Master Nuwa, where is the source heaven soul power most abundant during the source heaven period?" Zhang Su thought for a while and asked.

"There are three places where soul masters gather, such as the sacrificial spirit village, Tongxuan Valley and the first line of heaven." Nuwa's remnant soul searched through the remnant soul's spiritual consciousness and said three terms that Zhang Su had never heard of.

"The sacrificial spirit village should be the village where the ancient soul masters gathered during the sacrifice, and now I guess I can't find that kind of place, but I can't guess what this Tongxuan Valley and the first line of heaven refer to, can Master Nuwa solve the puzzle?" Zhang Su asked while pondering.

"I don't know the specifics, I don't have any memories of these two places in my remnant soul, I only know that when my body is in the Heaven and Earth Realm, it will go to these three places to connect with the Taoyuan Realm, and after each connection, there will be a lot of Source Heaven Soul Power from the Taoyuan Realm scattered around there, and its richness is far from being comparable to the soul power of the Heaven and Earth Realm." Nuwa's remnant soul explained.

"The point of contact between the ancient period and the Taoyuan realm?" Zhang Su muttered, he thought about the places that might be called "Tongxuan Valley" and "A Line of Heaven" according to the description of Nuwa's remnant soul, and after thinking for a long time, he didn't have a clue, and finally decided to leave this question for later to explore.

"I know, master, how to maintain this Horcrux with a Horcrux, I don't know the knowledge of Horcruxes, and naturally I don't know how to make a Horcrux with an Horcrux grow into an ancient Horcrux, I have to ask you for advice on this." Zhang Su asked respectfully at Nuwa's remnant soul.

"It's not difficult, soul power feeding must be indispensable, spiritual assimilation also has to be done, the most important thing is that you need to cut the soul and feed the spirit, over time the machine spirit can identify the person who feeds it as its master, and the machine spirit will become more and more powerful, and the result of the strong machine spirit is that the ability of the horcrux is getting stronger and stronger." Nuwa's remnant soul said.

"Cut the soul and feed the soul?" Zhang asked puzzled.

"That's right, in ancient times, eagle keepers would cut meat and feed eagles, in order to be able to influence and tame eagles, and the same is true between people, if someone can sacrifice themselves for others, and someone can be kind and charitable, then people can make the person who gets the charity return to their hearts, and the same is true for taming the machine spirit, if you don't feed the instrument spirit with your own main soul, the machine spirit will be estranged from you and cannot return to the heart, and it will not be driven by you in the future." Nuwa's remnant soul said.

"Cut off a part of your soul to feed the Spirit? Wouldn't that hurt? Zhang Su pouted and said, usually if a certain part of the soul is injured, the same pain will occur relative to the body, maybe it can't be seen from the outside, but the pain is real.

"Cutting the soul is actually much easier than cutting the meat, every time you cultivate some more souls like sarcoma in your soul, when you need it, you will remove this sarcoma soul and feed it to the machine spirit to eat, so that your soul will not be damaged, and the machine spirit will be more obedient to the master, this is the best of both worlds that the ancient soul master came up with." Nuwa's remnant soul said.

Zhang Ji pondered for a moment, the method that Nuwa Remnant Soul said was really good, using his own soul deity to cultivate the soul tumor, as long as he did not inject spiritual consciousness into it, then there would be no pain when he removed it, so that he would not damage his own body and soul, it seems that the wisdom of the ancients is indeed a lot.

Just when Zhang Su and Nuwa's remnant soul were constantly discussing the matter of the machine spirit, in the corridor, the sound of a hard-soled rubber shoe stepping on the concrete floor sounded, and this sound was getting closer and closer to the storage room where Zhang Su was, needless to say that Zhang Su knew that this was Zhong Tianli coming back from Yan Hunshan.

Listening to the tapping sound getting closer and closer, Zhang Su hurriedly put the incense burner horcrux back in place, and then quickly restored the messy storage room, leaving only the "Brief Description of the Soul Realm" in his hand and constantly flipping through it, making it look like he was reading the book seriously.

"Boy, did you find what you were looking for? Has anyone ever come to me during this time? As soon as Zhong Tianli entered the storage room, he asked Zhang Su.

"Tell Mr. Zhong, what I want has been found, and no one has come to you during this period." Zhang Su showed a well-behaved appearance and replied truthfully.

"Well, yes, it's quite reliable, your ability to look after the house is much stronger than Hu boy, that time he asked him to help me look at the research room, but when I came back, I found that there were two things missing, and finally I learned that Hu boy lent my things to Lin Yannizi and Jia Shuo's boy without permission, and actually confiscated the rent, since then I have never asked Hu boy to help me take care of the house, in terms of the ability to watch the house, you are better than Hu boy." Zhong Tianli looked around his research room and then happily praised Zhang Su.

"Housekeeping?" Zhang Su repeated, although Zhong Tianli said good things, but he always felt that something was wrong, and he wondered what it was that he had strong housekeeping skills, and finally remembered that it seemed to be a word that would only be used to praise dogs.

"I'll take a look, I'll take a look, what you're looking for is this "A Brief Introduction to the Soul Realm", it's actually useless, some of the content is outdated, and some of it is too false, and this book is written by a half-soul person with yin and yang eyes, and a lot of the content has mythological elements, which is not suitable as the basis for the soul master realm." Zhong Tianli commented on the book in Zhang Su's hand.

"Well, what the seniors Zhong said is that the juniors also think so." Zhang Su followed Zhong Tianli's words, wanting to pave the way for what he wanted to say later.

"There are a lot of books in my research room, such as "Soul Realm" written with special soul power characters, "Soul Immortal Journey" written by Mr. Nan Guo, the first person in the Soul Master Realm, and a guide to the production and operation of Horcruxes, those books are much more useful than this." Zhong Tianli continued.

"I wonder if Senior Zhong will allow me to borrow it?" Hearing that there were other literature, Zhang Su was naturally reluctant to let it go.

"Yes, but you have to pay the borrowing fee, I have a total of eight books, borrowing a book is three yuan a day, if you package the loan, I will give you a discount, eight books for a month of borrowing period, I only charge you thirty yuan, how about it?" Zhong Tianli looked at Zhang Wei with a grin.

"Huh?" Although Zhang Su had heard that Zhong Tianli was a little slammed, he felt that this person was still very generous and hearty when he borrowed the key from him before, but now that he heard that Zhong Tianli had to charge for borrowing a few books, Zhang Su suddenly understood where Zhong Tianli's rumors of slamming the door came about, and opened his mouth in surprise.

"Ahhhh Old man, my price is not high, and you can borrow books outside for more than that. Zhong Tianli snorted coldly.

Zhang Su thought about it, he still had a report about the incense burner horcrux later, in order to talk well in the future, it was not suitable to offend this old and somewhat eccentric guy now, and then replied with a smile: "I mean I didn't expect the borrowing fee issued by Senior Zhong to be so low, just a little surprised, Senior Zhong, I borrowed all eight books, packaged and borrowed for two months, and I will use my mobile phone to transfer sixty to you later." ”

"You still know the goods, I don't want to transfer money, you can take the book away first, and send the money over within three days." Zhong Tianli turned his anger into amusement and said to Zhang with a smile.

"Okay, by the way, Senior Zhong, I have one more thing I want to tell you." Seeing Zhong Tianli laughing, Zhang Su knew that Zhong Tianli was in a good mood at this time, and wanted to take this opportunity to drag out the matter of the incense burner Horcrux completely, so as to ask Zhong Tianli to forgive him.

"What's the matter? Want to rent a Horcrux from me? Zhong Tianli asked with a smile.

"That's not it, what I want to say is can you sell me this incense burner-like Horcrux?" Zhang asked timidly.

"Not to mention the old man, my Horcruxes are only rented and not sold, and even if they are to be sold, I will not sell Horcruxes that are in the pregnancy period." Zhong Tianli's face changed very quickly, and after hearing that Zhang Su wanted to buy a Horcrux, Zhong Tianli instantly showed an expression of rejection.

"That, don't hide it from the old man Zhong, that incense burner horcrux has passed the gestation period, and it has successfully conceived the machine spirit, but some accidents happened during the period, I accidentally helped the machine spirit to conceive, and as a result, I was swallowed up by the machine spirit during the gestation period Some soul power, so ......" Zhang Su explained guiltily, and did not hide the slightest thing about the machine spirit recognizing the master.

As Zhang Su spoke, he saw Zhong Tianli's face gradually become angry, Zhong Tianli is a soul master who specializes in horcruxes, so he naturally heard what Zhang Su meant, and without Zhang Su continuing to speak, Zhong Tianli had already shown an expression of wanting to tear Zhang Su apart, and the blue tendons on his forehead were rising.

"So the spirit of this Tutun furnace regards you as its master, right? Bastard? Zhong Tianli interrupted Zhang Su's words and asked sharply.

"Well, Senior Zhong is sorry, this ...... It was just an accident. Seeing that Zhong Tianli was about to be furious, Zhang Wei explained weakly.

"Accident, the Horcrux I worked so hard to make recognized you as the master, and you were embarrassed to tell me that it was an accident, and this Horcrux gave birth to a spirit and already has the possibility of becoming an ancient Horcrux, this kind of Horcrux that is worth even the city has been possessed by you, and you are telling me that it is an accident now?" Zhong Tianli looked at Zhang Su with a gloomy face, and kept asking, he didn't believe that an accident could make the machine spirit recognize the master.

Zhong Tianli questioned Zhang Su, while exuding a huge amount of soul power from his body, approaching Zhang Su step by step, as if he wanted to vent his anger at Zhang Su, judging from the pressure of Zhong Tianli's soul power, Zhong Tianli was only a little weaker than Yan Huishan, this powerful soul power showed that Zhong Tianli's strength was at least at the intermediate soul ancestor level.

Seeing Zhong Tianli's majesty, Zhang Su no longer knew what Zhong Tianli would do to himself next, but Zhang Su knew in his heart that if this matter could not be explained well, Zhong Tianli would definitely not give up, and it was very likely that he would directly abolish himself, and he might also abolish the incense burner horcrux called "Tudun Furnace", in short, this matter would not be easily turned over.

"Senior Zhong, I really didn't mean it, you listen to me explain first, if I'm really wrong, it's not too late for you to do it." Zhang Su pleaded as he moved his body back.

"I'll give you three minutes, and you can explain this to me now, or I'll kill you and make this Tutun furnace unclaimed again." Zhong Tianli said coldly.

After listening to Zhong Tianli's words, Zhang Su felt that there was still a glimmer of hope, carefully arranged the previous events, picked up what could be said and mixed it into a reasonable story and explained: "That's the case, I was looking at the book, and as a result, there was a violent soul power fluctuation in the incense burner horcrux, I remembered what Zhong said before, and I was afraid that there would be ghosts in this incense burner horcrux, so I used my soul power to probe, but I didn't expect that the spirit of the instrument really woke up, but it was extremely violent, and there were faint signs of becoming a ghost." So I wrestled with the rampaging machine spirit, and finally the soul power of the machine ran out and went into a deep sleep again, and after a while, the machine spirit woke up again, and then it took me as its master. ”

"Berserk? Ghosts? How do you know that the ferocity of the machine spirit during the gestation period is a sign of the formation of ghosts? I don't remember ever telling you about it. Zhong Tianli asked.

"This, oh, by the way, this content was seen when I was training as a newcomer in the Heavenly Soul Castle, and it seems that I read it in a certain book in the Heavenly Soul Pavilion." Zhang Su definitely couldn't confess Nuwa's remnant soul, so he could only arrange a possible situation.

"Heavenly Soul Pavilion still has this kind of book? But the rest of the content is not much different, indeed, when I used my soul power to probe just now, I sensed that there was still a little violent soul power in the Tudun furnace, which confirmed what you said about the mutation. After listening to Zhang Su's explanation, Zhong Tianli unloaded some soul power slightly, and did not continue to exert coercion on Zhang Su, but he still looked at Zhang Su with a suspicious face, and he still didn't believe the story described by Zhang Su.

"Well, I just made a move to prevent the mutation of the machine spirit, because I watched the door for you, under the peach tree and plum, I was afraid that you would blame me for the mutation of the machine spirit, so I wanted to suppress the mutation of the machine spirit first, so as to ensure the normality of the Horcrux, but I didn't expect the mutation to be suppressed, but let this machine spirit recognize me as the master, I really can't argue." Zhang Su responded with a slight cry.

"Although I also expected the mutation, it was just a little earlier than I expected, by the way, Zhang Wei boy, you explain to me how you suppressed this spiritual mutation?" Zhong Tianli asked.

Zhang Su thought about it seriously, he was afraid that Zhong Tianli was deliberately setting a pit for him, so he said cautiously: "I just simply use soul power to compete with it, it controls the soul spirit space to release the ghost fire wave, my soul keeps using soul power to resist in it, and when the soul power of the machine spirit is almost consumed, the machine spirit will no longer be violent, and will fall into a deep sleep again, I am afraid that she will die after she has no soul power, so I fed it a little more of her soul power, and it slowly woke up." ”

"No wonder I haven't been able to give birth to a machine spirit once in so many years, maybe I'm lacking some kind of means, your kid's method can be used, this is the first horcrux I made that successfully gave birth to a machine spirit, it's a pity that this machine spirit recognized you as the master, hey, maybe it's providence." Zhong Tianli unloaded the soul power on his body and sighed.

Seeing that Zhong Tianli didn't seem to be angry anymore, he let go of his heart in his heart, he smiled secretly, Zhong Tianli said that it was the will of heaven is not an exaggeration, the Nuwa who gave him a hint is not a god in the eyes of others, maybe everything that can be called the will of heaven has an unknown human man.

"Then I wish Senior Zhong can make more ancient-level Horcruxes." Zhang Su joked with a smile.

"Don't be smiling with me, you haven't solved the matter of messing with my Horcruxes casually, what do you say should I do?" Zhong Tianli pretended to be angry again and asked Zhang Su.

"It's still Senior Zhong, you have an idea, after all, it's the kid I accidentally moved your brainchild, even if you want to beat and punish the little one, I don't dare to talk back to you." Zhang Su knew that he was at fault first, of course he didn't dare to talk nonsense, so he could only politely admit it.

"Okay, I won't argue with you junior, so let's sell you this Tudun furnace, I know you don't have any money, so I don't want your money anymore, you can help me find three things." Zhong Tian left the road.

"Looking for what?" When Zhang Su heard that he didn't want money, his face was already happy, but when he heard Zhong Tianli say that he was looking for three things, Zhang Su knew that this matter would not be so easy to pass, so he asked puzzledly.

"It's not difficult, the top-grade soul crystal, the seven-leaf Lanling soul grass, the shell of the wide-striped armor turtle, the kind with a texture that is one finger wide." Zhong Tian left the road.

"Huh?" Zhang Wei's eyes widened, he had never heard of these things.
