But what went wrong, Ding Qi's mind turned, but he didn't have any clue for a while.

He felt that if this body was really extra-legal true breath and showed some kind of ability, although it was related to this anchovy grass, it should not be the point.

Anchovy, most likely, is only an incidental effect, and the real ability should be in another aspect.

Although Ding Qi has this feeling in his heart, he is not sure. After all, he was still unsure whether the golden true breath in his body was the so-called 'extralegal true breath'.

In the end, a look of helplessness appeared on his face, and he was once again confused about the situation of the golden true qi in his body.

At this time, the contents of the ring, after half a day, were completely inspected by Ding Qi. After reading the pill book that recorded a lot of miscellaneous things just now, Ding Qi had a better understanding of the things in the immortal cultivation world.

While Ding Qi was distressed about the matter of the golden true breath in his body, he couldn't help but cast his eyes on the nearly twenty jade boxes on the table.

After reading the book just now, Ding Qi also knew what was in these jade boxes.

Inside these jade boxes is something called a 'magic crystal'. In the world of cultivating immortals, they exist as currency.

The magic crystal contains abundant spiritual power, which can be absorbed and refined by cultivators. When an immortal cultivator was cultivating, if he was holding a magic crystal in his hand, his cultivation speed would immediately become extremely fast.

This kind of speed is much more than the spiritual power that escapes between refining heaven and earth, and it is an extremely precious thing for immortal cultivators.

However, this magic crystal is a consumable thing, as long as the immortal cultivator refines the power inside, the magic crystal itself will immediately shatter and become something of little use.

In addition, this magic crystal can only be collected in some extremely rare special ore veins, which is extremely difficult to obtain, and it also makes most immortal cultivators not qualified to use such a luxurious method to cultivate.

In addition to helping immortal cultivators to cultivate, the magic crystal is also a necessary thing for arranging most of the magic circles. In the circle, this kind of thing must be embedded as a source of energy in order to function.

Among them, the larger and more complex the magic circle, the more it consumes the magic crystal, and the greater the dependence.

For example, the Ghost Spirit Array, which only needs to absorb the spiritual power escaping from heaven and earth to be able to maintain its own operation, is only a very few, and there are only a few in the Immortal Cultivation Realm.

This magic crystal can not only be used for cultivation and formation, but also can be used as a supplement to fill one's body and consume mana. For an immortal cultivator like Ding Qi, even the mana in his body is consumed because of overuse. A small magic crystal is enough to replenish the mana consumed in the body at a very fast speed in a very short time.

It can be said that if Feng Yuanzi had a magic crystal in his hand when he was in the underground palace, he would not have needed Ding Qi to help him open the magic circle, and he could quickly replenish the mana in his body and open it.

It's a pity that Feng Yuanzi, for the sake of insurance, stored all the magic crystals in the copper ring and sealed them in the study behind the stone door.

In addition to these main uses, the magic crystal also plays a very important role in many other places, and the uses can be described as extremely numerous.

Therefore, in the world of cultivating immortals, the precious thing of the magic crystal has gradually become an existence like currency, and you can use this thing to exchange for what you want.

The spiritual power contained in these magic crystals also has various attributes according to the different elements and yin and yang. The magic crystals of different attribute powers can be distinguished from the color of their appearance.

This is also the reason why among these jade boxes in front of Ding Qi, the magic crystals will be placed in different jade boxes.

They are all stored according to different attributes.

Of course, among the power contained in the magic crystal, in addition to the most basic attributes such as the five elements and yin and yang, there are also some peculiar attributes. However, it is generally difficult to see the magic crystal of this kind of attribute.

Their value is far from being comparable to ordinary law crystals.

Ding Qi casually picked up a jade box in front of him and opened it, looking at the bean-sized magic crystal inside, feeling the fluctuations of spiritual power inside.

Among the twenty jade boxes, there are nearly two thousand magic crystals, and Ding Qi doesn't plan to use them now.

He still has a box of Gathering Spirit Pill in his hand now, which is enough for Ding Qi to use for a long time if it is used to cultivate innate skills. In addition, in the center of Qixia Mountain, there was a batch of two-hundred-year-old medicinal herbs, and he also planned to take them all back and use them to refine the elixir.

After having these things, his future cultivation will be for a long time, and he will no longer have to worry about the elixir, and naturally he will not waste such a precious thing as the magic crystal.

The role of the magic crystals in these jade boxes, Ding Qi has already figured it out. After putting this box back in, Ding Qi unconsciously moved his gaze to another jade box.

This is the box with the jade plaque on it.

Except for the books he couldn't read, and the jade box that couldn't be opened, there was only the rather mysterious-looking jade plaque left, which made him feel distressed.

"This jade plate, I don't know what is special, Feng Yuanzi did not put this thing into the brass ring, but put it in a jade box alone. Thinking of this, Ding Qi took out the jade plaque from the box, looked at it twice, and tried to inject mana into it.

At this time, a ray of light emanated from the jade plaque, threw it at a jade box on the table, and swept over the jade plaque.

Seeing this scene, Ding Qi suddenly showed a look of surprise on his face.

Ding Qi was in the dungeon, and when he got this jade card, he used to try to input mana into it, but there was no reaction at that time.

This time, he took out the jade plate from the jade box and entered the mana again, but a vision occurred.

Ding Qi looked at the extinguished light in his hand with a puzzled face, and then looked at the jade box that had been swept over: "I remember, this jade box is...... The one that was taken out of the ring and could not be opened. ”

"Could this token actually be the one who opened the jade box just now?" An idea suddenly popped up in Ding Qi's heart.

He reached out and took the box in his hand, looked at it carefully, and tried to reach for the lid with his other hand.

Ding Qi used a slight force in his hand, this jade box that could not be opened before, under the sweep of the white light thrown from the jade plate just now, this time it was easily opened.

The moment the box was opened, a crystal green light shone out of the box.

Ding Qi looked at the open box with a look of surprise on his face. He knew very well in his heart that according to his previous judgment of the situation of this jade box, the contents of this box were probably the most precious things in Feng Yuanzi's collection.

"I don't know what the most precious thing in the ring is. ”

As the opening thing of this box, the jade plate was actually placed in two completely different places by Feng Yuanzi and the copper ring ring, and Ding Qi was now even more convinced in his heart that the things in this jade box were definitely extremely precious.

Ding Qi looked at the jade box, and even began to suspect that if the jade box was not opened in this correct way this time, but in some kind of brutal method he used in the future, if he wanted to open it rashly, it was likely to cause unknowable consequences, and it was impossible to destroy the jade box and the contents together.

The thoughts swirled in his mind, but he didn't stop. After the jade box was opened, Ding Qi couldn't wait to look inside the jade box to confirm what was inside.

Ding Qi saw that a piece of jade-like thing wafting with a dense aura stayed quietly inside the box, emitting a crystal green light outward.

This thing, at first glance, looks like some kind of solid, but if you look closely, you will feel that it is not so simple. This green jade-like thing seems to be transforming from solid to gaseous all the time.

In general, this thing gives Ding Qi a peculiar state formed by the condensation of some kind of green mist, with steam-like things in it, constantly tumbling and changing, which gives people a strange feeling.

When opening the jade box, Ding Qi could feel a wave of essence energy from this object, sweeping from his body, so that the pores of Ding Quan's body were instantly opened and began to be comfortably greedily absorbed.

However, this energy fluctuation only appeared for a very short time, and then it was confined to the interior of this strange substance, as if it had never appeared.

It was only at this time that Ding Qi recovered from the extremely comfortable feeling just now, and looked at the thing in front of him with unfinished eyes.

"This kind of thing, in the books I read before, seems to have been mentioned. After Ding Qi came back to his senses, he looked at the thing in front of him suspiciously, and suddenly realized that he seemed to have mentioned something similar to the thing in front of him in the books he had read before.

However, in those books, he had read too much unfamiliar knowledge, and although Ding Qi now realized that he had seen the characteristics and similar contents of this thing in front of him not long ago, he couldn't remember it for a while.

Ding Qi squinted his eyes and looked at the green jade-like thing in front of him, trying to recall what he had read before. Soon, he finally remembered in which book he had seen something similar.

There is something in front of you, and a similar record is the book with the content related to the phoenix grass and the spiritual vein.

After recalling what he had seen about the similarity of the things in front of him, Ding Qi stood in place for a long time, with an indescribable look on his face.

"This thing, could it be...... The eye of the spiritual vein. Ding Qi looked at this object, took a deep breath and muttered to himself.

"But Feng Yuanzi, how can there be such a thing. According to what the book says, isn't this kind of thing only available to those powerful immortal cultivators who are qualified to have it, and it exists as the treasure of the town sect!"

Ding Qi couldn't help swallowing his saliva and said slowly.

(After the third watch, I ask you for a recommendation ticket and collection.) ）
