This trip to the underground palace, just from the time alone, is actually not long, and it is only a few days in the underground palace. But there's just so much going on.

During this period, Ding Qi experienced various traps in the dungeon, and later learned that Zhang Tao was dead, and there was a vicious fight with Feng Yuanzi who was almost alive, and he also learned a lot of incredible information from this person.

These things are almost more than all the experiences he had in his life.

Coming out of the underground palace, doing it again in the medicine garden, smelling the familiar medicinal fragrance emitted by various herbs in the medicine garden, Ding Qi thought back to what had happened in the past few days, and suddenly had a sense of amazement.

But he didn't have much time to sigh now, Ding Qi looked at the copper ring in his hand, and his face showed a cautious look.

This copper ring ring, which only made the mana in his body fluctuate, Ding Qi has been extremely concerned about it since he was brought out of the underground palace. Now that he had also returned to the medicine garden, he was finally able to calm down and figure out the situation of the ring in detail.

Ding Qi took the ring in his hand and played with it carefully, feeling the mana in his body, and all kinds of fluctuations because of the existence of the ring. There was a faint feeling on the ring, wanting to absorb the mana in Ding Qi's body.

After playing with it for a while, he had the most basic understanding of the situation of the ring: "Although this ring, I don't know what it does." But it seems that it should be necessary to input mana into it first. ”

Thinking of this, Ding Qi's mind moved slightly, and the mana in his body slowly entered the ring.

Under the injection of Ding Qi's mana, the brass ring in his hand began to flash a faint light, and Ding Qi was overjoyed when he saw this.

Next, he continued to inject mana into it, and after that, he clearly felt that he had broken through a certain threshold.

Then, a space inexplicably appeared in Ding Qi's mind.

Ding Qi was surprised at first by this inexplicable change, but then he quickly realized something, and looked at the copper ring in his hand with surprise on his face: "This ring, is it a legendary ...... Mustard seeds turn Sumeru. ”

Among the legends of immortals and monsters in this world, there are many legends of this kind of Sumeru space. After this trip to the underground palace, Ding Qi knew that he was practicing the rumored immortal cultivation method, and he was already an immortal cultivator, so it was extremely normal to be able to encounter this kind of legendary thing this time.

This copper ring is also the thing of Fengyuanzi, and it is not surprising that this person can have this kind of thing.

Although he figured this out in his heart, the excitement on his face when he encountered such a magical thing could not be dissipated in a short period of time.

Ding Qi felt the inexplicable space in his mind, took a deep breath, focused his attention on various things in the space, and his mind moved with it.

Then, something from a place appeared in front of Ding Qi's eyes out of thin air.

Although Ding Qi had been prepared for this for a long time in his heart, he was still stunned when he saw that there was really something that was taken out of the ring under the lock of his own thoughts.

Soon after, Ding Qi was attracted by a stall on the ground. Most of these things were jade boxes, and there were a few books inside, as well as a few jade bottles and some swords and armor that Ding Qi couldn't figure out.

"No wonder there was nothing in the study except for a few books. It turned out that this Feng Yuanzi contained all the things in this ring. Ding Qimo rubbed the ring in his hand and muttered to himself.

After that, Ding Qi locked all the remaining things in the ring and took them out of it.

Ding Qi looked at the items on the ground, and finally began to carefully examine these things that Fengyuanzi had collected two hundred years ago.

He put them on the table one by one and examined them carefully.

Under Ding Qi's examination of these things, half an hour passed quickly, and he finally finished the general examination of these things.

There were dozens of things he had taken out of the ring before. It stands to reason that it will not take such a short time to inspect one by one.

However, when he checked it just now, Ding Qi found that most of the jade boxes contained similar items. Among the nearly twenty jade boxes, he found that what was placed inside was something the size of a bean grain that exuded a faint luster, like jade but not jade.

These bean-like things, the whole body is crystal clear, with six or seven colors, and they are also classified in different jade boxes according to different colors. In each jade box, there are about a hundred grains. Ding Qi could feel a power fluctuation from these items, but what was the use, Ding Qi couldn't figure it out for a while.

The rest of the swords, armor and other items, after Ding Qi checked them and injected mana into them, he probably figured out what they did. Ding Qi estimated that these things should be so-called magic weapons, and looking at their shapes, those sword-style ones are probably offensive magic weapons. The armor style is a defensive magic weapon, just like the pale silver armor that Feng Yuanzi wore and was later taken out of the dungeon by Ding Qi.

Ding Qi also checked the various jade bottles taken out of the ring, and found that all the pills were placed inside. However, what the specific effect of these pills is, with Ding Qi's knowledge, it is naturally impossible to distinguish.

After examining the pills in these jade bottles for a while, Ding Qi could only put them away again first, put them aside, and wait for later.

However, during this period, when Ding Qi checked the jade box, there was a jade box in it, and Ding Qi couldn't open it no matter what.

Ding Qi looked at the jade box in front of him at this time, which could not be opened, with a helpless look on his face. He also knew that what was in it was probably the most precious thing in the ring.

"I don't know what the hell is in here. Ding Qi sighed and looked at the jade box, thinking silently in his heart.

For a while, the more the jade box could not be opened, the more Ding Qi looked forward to the contents inside.

"Since this jade box can't be opened for the time being, we can only find a way in the future. Now, let's take a look at what is recorded in those books. Thinking of this, Ding Qi took a few books on the table in his hand and opened one of them.

He opened the book in his hand, and there was a somewhat cold touch on the pages. This book was placed in the original study, two hundred years old, but it was not damaged much, and it didn't look too old, Ding Qi saw this, and realized that the pages of this book were obviously not mundane things, and they should also be made of a strange material in the world of cultivating immortals.

Ding Qi didn't pay much attention to these, but began to take a serious look at the content recorded in it.

After he turned the pages of the book, Ding Qi quickly discovered that what was recorded in the book was the knowledge of the so-called 'spiritual veins' in the immortal cultivation world.

In this book, Ding Qi finally learns that there is something called 'aura' between heaven and earth. Immortal cultivators can absorb aura and refine it into mana to cultivate. After Ding Qi cultivated to the eighth layer of innate skill, the mysterious power that he felt between heaven and earth was replenished into his body, allowing him to survive without eating and drinking, which was actually spiritual power.

The so-called spiritual veins are where the spiritual power is formed by the aggregation of spiritual power in accordance with the rules of heaven and earth. Above the spiritual veins, the thickness of the spiritual power is hundreds of times higher than that of ordinary places. Generally, only in this kind of place is it suitable for immortal cultivators to cultivate.

If it is an ordinary place, although there is also spiritual power in the space, but just if you want to extract it and use it for cultivation, it will take a lot of effort, and the efficiency is extremely low. Compared to cultivating in a place where there are spiritual veins, it is likely to take more than ten times slower. Even in some places where spiritual power is even thinner, the power spent by the immortal cultivator himself to extract the spiritual power in the space is likely to be more than the spiritual power that can be absorbed and refined into his body, so the gain outweighs the loss.

According to the records in this book, all the great sects of immortal cultivation in the world also build their foundation on the spiritual vein. Only in this way can we ensure that the sect will continue to multiply for thousands of years and prosper from generation to generation.

This book also introduces that the spiritual veins themselves are also divided into grades, and the spiritual veins of different grades are even more different. Among them, the more powerful the sect, the more high-end the spiritual veins it occupies. The same amount of time it takes, the faster the immortal cultivator can cultivate above the spirit vein.

At this time, Ding Qi looked at the content of the spiritual veins introduced in the book page by page, and looked like he was relishing.

Ding Qi knew that the content he saw was probably something that most immortal cultivators knew. However, for him, this knowledge was something he really needed, and he was quite hungry for a while.

"Hey, there's actually a record of the content of anchovy grass in this. Just when Ding Qi carefully flipped through the contents of the book, and opened the next page, and saw the relevant content recorded in it, Ding Qi suddenly showed a look of surprise on his face.

(In the last two chapters, there was no description of the content of the armor that brought out Feng Yuanzi, but we have now revised and made up for it.) In addition, today's three watches are over, let's ask you for recommended tickets and collections. ）
