Suddenly, Zhang Ling saw a woman in red flipping through books on the side of the bookshelf. Instinctively, a flash of light appeared in his eyes, and Zhang Ling's expression changed. He quickly turned his head to the other side, not daring to look at the female cultivator again. This woman was also a Golden Core cultivator. Apart from this woman, there were no other cultivators in the hall. It seemed that very few cultivators came here. But thinking about it, most of the cultivators who could enter this third floor had Golden Core cultivation. And that female cultivator seemed to be immersed in the books and hadn't noticed him. Zhang Ling breathed a sigh of relief and didn't think too much about it, walking to the other side. First, he circled around the surroundings. This was a circular space, about thirty to forty zhang in size. Strangely, three to four zhang above his head, there was a white, hazy area where he couldn't see the top. This situation clearly indicated a powerful restriction. Besides a few books, there was nothing else in the space in front of him. However, on the surrounding walls, there was a doorway every so often.

There were a total of eight arched stone doors, all wide open with darkness inside. Looking at their arrangement, it seemed to be based on the Eight Gates of the Nine Palaces formation. When he scanned with his divine sense, he could only see some words engraved next to the mountain gate, and once his divine sense probed inside the mountain gate, it would be swallowed by endless darkness. Seeing this, Zhang Ling no longer recklessly used his divine sense to investigate. However, just by observing with his naked eyes, he could still see the words next to the nearest few stone doors. On one of the doors, the ancient characters for 'Five Elements Cultivation Methods' were engraved. Another door was labeled 'Esoteric Secret Techniques'. It seemed that behind each door, there were many books. Zhang Ling roughly scanned around and then withdrew his thoughts, focusing his attention on the bookshelves. These bookshelves also each had a small plaque with text on them. After scanning a few times, Zhang Ling walked towards a redwood shelf that was only about a zhang tall. This shelf had the ancient characters for 'Cultivation Experience' written on it, which was exactly what he was looking for. He casually picked up a white booklet with 'Green Wood Spell Experience' written on it. Zhang Ling flipped through it a few times and then picked up another book to read. He stayed in front of this bookshelf for almost half an hour, reading through all the books on it. On one of the wooden shelves, he also found the Golden Core Formation Experience he needed, and there was more than one copy, about seven or eight. After selecting for a while, Zhang Ling took a book called 'Earth Element Core Solidification Record' and returned the way he came to the previous passage. The 'Earth Element Core Solidification Record' recorded the experiences of two cultivators who practiced earth-attribute cultivation methods in forming their Golden Cores. The other Golden Core Formation Experiences were roughly the same, but the book in his hand now did not contain a complete record. To get the complete version, he would have to get the consent of the previous Golden Core elder. Before long, Zhang Ling saw the old man again. After taking out the book in his hand, the old man didn't seem surprised, but just opened his mouth and said in a muffled voice, 'Now that you've chosen, let me tell you the rules.' 'The price for the complete Golden Core Formation Experience here is uniform, ten thousand spirit stones.' 'Ten thousand spirit stones.' Hearing this price, Zhang Ling's face showed a surprised expression. His heart also sank. It wasn't that he couldn't take out ten thousand spirit stones, but he didn't want to attract the attention of this Golden Core elder. The old man looked at Zhang Ling's expression and didn't seem surprised. He had seen this kind of expression many times.

Ten thousand spirit stones was not too much for a peak Foundation Establishment cultivator, but it was not too little either. Not many could easily take it out. While Zhang Ling looked embarrassed and hesitated, the old man pointed at the book in his hand. The book in Zhang Ling's hand flew into the old man's hand, and then a wisp of red light appeared in this person's hand, turning into several runes that entered the book. Suddenly, the book flashed with spiritual light, and a fist-sized ball of light emanated from it. Then it split in two, turning into two black pieces of paper. Zhang Ling saw this change and wondered if this person was removing the restriction on the book. The runes on the black paper flickered twice and then turned into two copper coin-sized light spots. 'Senior, is this the Divine Sense Aura?' Seeing this, Zhang Ling couldn't help but ask. 'Boy, you have some knowledge. This is the complete experience in this book. The cultivation methods above this third floor have special restrictions, and even I can't take them out. Ten thousand spirit stones is already the lowest price.' The 'Divine Sense Aura' was a usage of divine sense, a special method of dividing a part of the divine sense to record information. Only cultivators above the Golden Core stage could use it. Ordinary books and jade slips mostly recorded text-based information, and even image-retaining beads were just special props for recording pictures and sounds. But the information recorded with the Divine Sense Aura method had a special effect, which was to record a part of the cultivator's insights. A cultivator's insights were also experience, and this abstract thing was difficult to record in books. Originally, Zhang Ling thought that the Golden Core Formation Experience was the same as other books, paper-based information, but he didn't expect that the Golden Core Formation Experience here was recorded using this method. Ten thousand spirit stones was not spent in vain. Zhang Ling thought to himself, but he calmly replied, 'Thank you for your guidance, Senior. Here are ten thousand spirit stones, please verify.' A large bag was taken out by Zhang Ling and placed on the ground. It was filled with low-grade spirit stones. The old man glanced at the large bag and smiled at Zhang Ling. 'Okay, come forward, and I will pass this experience on to you.' 'Thank you, Fire Dragon Senior.' Zhang Ling took a few steps forward and bowed to the old man again. Zhang Ling also nodded, and without seeing any movement from him, the two light clusters in his hand flashed and arrived in front of Zhang Ling. 'Concentrate and receive the experience inside.' The old man's muffled voice rang in Zhang Ling's ears, and he saw one of the light clusters disappear into Zhang Ling's brow. Zhang Ling immediately felt an extra piece of information in his mind. This information was not much, but it was very pure. After a quarter of an hour, Zhang Ling walked out of the third floor of the Myriad Dharma Building. After leaving, he didn't stop and randomly found an inn to stay for a few days. Zhang Ling didn't leave the inn at all. He stayed in the guest room, constantly digesting the experience in his mind. This kind of message conveyed by Divine Sense Aura was mostly special messages such as insights, which could only be understood implicitly and were quite mysterious. At the same time, the information recorded by this method could basically only be used once. Even the same high-level cultivator, using this method to record the same cultivation method insights, would not be exactly the same. There were subtle differences. And how much the cultivator who received the information could comprehend also varied. This Divine Sense Aura would not last too long after being transmitted, and would generally dissipate within a few days.

This was also the reason why Zhang Ling immediately comprehended it. He received the experience of two different cultivators. The insights had similarities and differences. In short, after Zhang Ling absorbed the insights in his mind, he also had some insights on breaking through the bottleneck. These insights were different for each cultivator in terms of their understanding of cultivation, their understanding of spiritual power, and even the laws of heaven and earth. In these few days, Zhang Ling had a feeling of enlightenment. When he circulated the spiritual power in his body, he didn't know if it was an illusion, but he felt that he had a better grasp of the spiritual power. Some of the doubts in his original cultivation were also suddenly cleared up. Zhang Ling knew that this state was because he had a deeper understanding of combat cultivation. This kind of spiritual perception was often the most difficult to figure out. After a full seven days, Zhang Ling left the inn with a relaxed expression and returned to Fire Cloud Island. Next, he began to prepare to form his Golden Core. …… As soon as Zhang Ling returned to his cave, he first set up the Six Jia Bewildering Divine Formation, and then he patted his storage bag and took out a wooden box, which contained three square jade stones and thirty-six fist-sized white light jade beads. After checking the jade stones and jade beads, Zhang Ling buried the three square jade stones next to the spiritual spring in his cave. Then he walked out of the cave and used the Wind Control Technique to travel. Zhang Ling directly dragged the wooden box and moved around the cave. Every so often, he calculated the position and bought a white jade bead. After spending most of the day, Zhang Ling placed all thirty-six jade beads. After Zhang Ling returned to the cave, he began to cast spells on the three jade stones. After a while, he activated the three jade stones. The three jade stones flashed and flew into the sky above the spiritual spring, and began to rotate slowly. At the same time, a layer of water ripples rippled out, forming a layer of translucent spherical water curtain around the three jade stones. Seeing this, Zhang Ling released his divine sense, and a divine thought invaded the water curtain, carefully sensing it for a while. However, the spirit stones were not spent in vain. These sensing beads really have some effect, and with these beads, the protection around the cave can be considered an extra layer of protection. The three jade stones and thirty-six jade beads are components and formation disks of a set of formations. The difference is that they are neither formations that protect the cave nor illusion formations, but special formations for sensing. Among them, the thirty-six jade beads are said to be materials from a monster called the Hundred-Eyed Demon. These jade beads are refined with special techniques, and can be connected into one to monitor an area. Each jade bead can monitor the space within half a mile, and Zhang Ling scattered thirty-six jade beads throughout the entire mountain. As long as other cultivators enter the mountain where his cave is located, he will know immediately. This set of special formations cost him a lot of spirit stones to buy from a shop specializing in selling formations. With this layer of invisible protection, the safety of the cave can be greatly increased. Next, Zhang Ling began to get busy. He first planted all the spiritual herbs he had collected in the medicine field. Only when the years were enough could he prepare the Yuanling Water, an auxiliary spiritual object for forming the Golden Core. …… On this day, a buzzing sound came from the foot of the mountain. Zhang Ling stood on a boulder, watching hundreds of earth spirit bees flying around him. These earth spirit bees were scattered within a four-mile radius. On his left hand, only one earth spirit bee was lying. This earth spirit bee happened to be the size of a hand. The difference was that its body was chubby, and it had two long red antennae on its head. And a pair of transparent wings on its back were glued to its back. Looking at its appearance, it seemed that it could not fly. However, Zhang Ling looked at the earth spirit bee in his hand, but he did not mean to underestimate this little thing at all. This is the queen of the earth spirit bees, and also the queen bee of the earth spirit bees. Half of Zhang Ling's credit for controlling the earth spirit bees depends on this insect.

Suddenly, Zhang Ling opened his mouth, and a somewhat harsh muffled sound came from his mouth. Then the earth spirit bee queen in his hand also鳴叫了起来, and suddenly hundreds of earth spirit bees flying around flew towards Zhang Ling densely. Zhang Ling raised his hand, and a green-skinned bag was thrown into the air by him, and he pointed at the bag with one hand. The bag swelled into a bag as tall as a person, and the mouth of the bag was also opened. Those earth spirit bees also entered into it one after another, and after the last earth spirit bee flew into the green-skinned bag, Zhang Ling waved his hand, and the green-skinned bag returned to its original shape and he grabbed it in his hand. Little guy, you did a good job. Zhang Ling touched the bee queen in his hand and chuckled. Then he put the bee queen into the green-skinned bag. Soon after, Zhang Ling came to a somewhat dim stone cave. He took out the green-skinned bag again and put all the earth spirit bees in the stone cave. This stone house was specially built, and after some transformation, it was used by him to cultivate those earth spirit bees. Zhang Ling got a total of three bee queens, and each bee queen could command thousands of earth spirit bees. It's just that these earth spirit bees are still larvae, and their strength is very small, but even so, thousands of earth spirit bees can deal with Qi Refining stage cultivators. Cultivate earth spirit bees. In addition to this stone room, there are two other identical stone rooms, all of which are occupied for cultivating earth spirit bees. He put the Divine Control Forbidden Curse on the three bee queens, which is used to control the earth spirit bees. However, it is not easy to control this kind of spirit insects with a large number. These spirit insects in groups generally have a insect king or a insect mother. Only by controlling the insect king and insect mother first can you control the spirit insects in groups. However, Zhang Ling also reversed that although spirit insects also have spiritual intelligence, they are not dead objects, but their spiritual intelligence is very weak. It takes a lot of divine sense to fully control the spirit insects. However, these are not what Zhang Ling needs to consider now. He cultivates earth spirit bees because he is interested in the honey they breed, which is used to condense spiritual power. And he can control the spirit insects so quickly, because in the storage bag of Elder Chen he obtained, there are related breeding methods. Reading it carefully can save a lot of time. And cultivating earth spirit bees is also quite simple for Zhang Ling. Although earth spirit bees also devour some mosquitoes and other insects. But most of their food source is still spirit flowers and spirit grass. Zhang Ling basically uses spirit flowers that have been around for hundreds of years to cultivate these spirit insects, hoping that they can grow quickly and breed the honey he needs. Zhang Ling basically spends most of his time cultivating and meditating except for feeding some earth spirit bees and taking care of the medicine field from time to time. He still has a little earth spirit bee honey in his hand that can supply him with cultivation for a period of time. In this way, Zhang Ling entered a semi-secluded state. In the next few years, he never left Fire Cloud Island.
