Let's talk about the spiritual herbs in the spiritual fields. Although Zhang Ling had been in seclusion for nearly thirty years, in reality, only a little over four years were spent in life-or-death situations. He could still spare some time to cultivate spiritual herbs during the rest of the time. Now, Zhang Ling's storage bag contains several millennium-old spiritual herbs, each with varying ages, mostly ranging from one thousand to two thousand years of potency. These millennium-old spiritual herbs are mostly grade-three spiritual herbs. Among them is a strange, dark, withered wood, over ten feet tall, completely bare without a single leaf. Seeing this wood, Zhang Ling was quite shocked. This was the Soul Nourishing Wood he possessed. Due to his breakthrough, he hadn't used many elixirs recently. The mysterious beads were used to cultivate spiritual herbs older than five hundred years, including several special spiritual trees that he focused on. The Soul Nourishing Wood is at least ten thousand years old. There's also a five-thousand-year-old Cassia Willow, a yin-attribute spiritual tree. The Soul Nourishing Wood is a divine wood. Zhang Ling used all the inexhaustible spiritual liquid from the mysterious small beads on this wood. Besides these two special spiritual trees, there's also a two-thousand-year-old Frost Bamboo and a Fire Flame Wood of similar age. These two spiritual trees were specifically cultivated to exchange for cultivation resources he would need in the future.

Although these two spiritual trees aren't considered rare, two-thousand-year-old spiritual wood is sufficient as raw material for refining magical treasures. He could naturally stimulate them further, allowing the spiritual wood to reach five thousand, or even ten thousand years. But Zhang Ling didn't do so. Apart from the Soul Nourishing Wood, which is over ten thousand years old, he doesn't plan to cultivate any other spiritual herbs or trees to ten thousand years. If the Soul Nourishing Wood wasn't special, not measured by age, and because this kind of divine wood is basically extinct, he wouldn't have cultivated it to ten thousand years. Rather than waste some of the mysterious beads' stimulating liquid, Zhang Ling wanted to ensure that the spiritual energy emitted by these spiritual herbs remained within a controllable range, undetectable by others. Millennium-old spiritual herbs contain a large amount of spiritual power, which even Golden Core cultivators rarely use. Elixirs refined from one or two-hundred-year-old spiritual herbs are sufficient. Zhang Ling didn't want to be discovered to possess millennium-old spiritual herbs, attracting disaster. If it weren't for exchanging some treasures after forming the Golden Core, he wouldn't have stimulated the growth of millennium-old spiritual herbs. The treasures needed by Golden Core cultivators are rarely found on the market. Exchanges are mostly done with other Golden Core cultivators in a barter system. After collecting the century-old spiritual herbs from the medicine field and taking the spirit beasts and mature earth spirit bees, Zhang Ling left Fire Cloud Island. ... After leaving Fire Cloud Island, he flew towards Myriad Manifestation City. A thin layer of yellow golden light floated around Zhang Ling. With a flash of light, he turned into a streak of afterimages, reaching a place more than ten feet away. He wasn't flying at full speed, but his speed was already three or four times faster than when he was still in the Foundation Establishment stage. The so-called flying through the air! The principle is simple. The Golden Core in a Golden Core cultivator's body contains powerful spiritual power. Releasing spiritual power around the body allows one to temporarily stay in the air. This is similar to the Floating Spell, which can also be used by those in the Qi Refining and Foundation Establishment stages. However, they can only stay in the air for three or four breaths at most. Golden Core cultivators, on the other hand, can stay in the air for more than ten breaths without deliberately casting a spell. While staying in the air, they circulate spiritual power to transform it into a small amount of wind spiritual power, achieving the purpose of flying through the air. Although wind-attribute spiritual power is a mutated spiritual power, it evolved from the power of the five elements.

Zhang Ling himself cultivates earth-attribute spiritual power. But now he is already a Golden Core expert. Transforming a small amount of earth spiritual power into spiritual power of other attributes is not difficult. This is how one flies through the air without the aid of magical artifacts. If he flew at full speed, he could be more than twice as fast. Of course, some Golden Core cultivators also use flying magical artifacts. Some specialized flying treasures are faster than ordinary cultivators' escape techniques. In addition to flying magical treasures, there are also sword cultivators in the Golden Core stage who fly on their swords, or specialized flying spells, and the Shadow Escape and Shadow Technique of the Demonic Path. Although the speeds vary, they are often incredibly useful. After flying for more than an hour, Zhang Ling arrived at Myriad Manifestation City. Approaching the outskirts of Myriad Manifestation City, he pondered for a moment and decided to keep a low profile. With a wave of his hand, the flying boat appeared under his feet, and his speed was reduced by more than half as he entered Myriad Manifestation City. It had been many years since he had come to Myriad Manifestation City, and it was still as bustling as before. Walking on a street, looking left and right, a feeling of both unfamiliarity and familiarity stirred in Zhang Ling's heart. This immortal city hasn't changed, the only difference is that Zhang Ling's state of mind has changed after returning to Myriad Manifestation City. In the following period, Zhang Ling would frequently enter and exit some shops. In these shops, he began searching for things useful to Golden Core cultivators. With his current Golden Core cultivation, he was treated like a VIP no matter which shop he entered. Generally, the people who received him were managers with at least a late-stage Foundation Establishment cultivation. During this time, he also saw several other cultivators with Golden Core cultivation. The things Zhang Ling is searching for now are mostly things that Golden Core cultivators would use. Therefore, there is no need to deliberately hide his cultivation. Besides, his previous Qi Concealment Technique doesn't seem to be a profound secret technique. As long as a Golden Core cultivator takes a few more glances, they can discover his cultivation. So why bother hiding his cultivation? However, Zhang Ling paid attention to such techniques. If he could find some profound Qi Concealment Techniques, he would still cultivate them. The purpose of entering and exiting these shops was naturally to inquire about cultivation techniques, which is his top priority now. Thus, Zhang Ling stayed in Myriad Manifestation City, basically visiting all the large shops and some bookstores. Zhang Ling also entered and exited many of the shops in the seamless areas of the city. But even so, he couldn't find a cultivation technique that satisfied him. This afternoon, in room six of the 'A' section of a tavern called Green Mountain Tavern, Zhang Ling looked at the two cultivation techniques placed on the table with some distress. The names of the two cultivation techniques are 'Earth True Great Method' and 'Heavy Mountain Thick Earth Art'. These two cultivation techniques are what he has collected during this period. Although these two cultivation techniques are not common, they are not profound cultivation techniques either. Even so, these two cultivation techniques cost him fifty to sixty thousand spirit stones.
