Zhang Naijing sold the first-order Lingbao Flying Sword at a high price and used the immortal stones he earned to open a shop.

Qin Di passed on to him a unique identification method called "Star Identification" to identify starfall fragments.

In order to perform star appreciation, there must be a "void breaking charm". Therefore, Qin Di refined several "Void Breaking Talismans".

The Starfall Fragment is essentially the Cave Heaven Remnant Core left behind after the fall of the Great Immortal, similar to the "Sumeru Space", which looks very small on the outside and has a piece of land inside. Because of the protection of runes, outsiders can't see through what's in the space, so there's no way to characterize the Starfall fragment.

Qin Di has a unique attainment in the Dan Weapon Rune Array, with his current skills, the refining of the Void Breaking Talisman can reach the point of the eighth-order treasure talisman, such a talisman to the starfall fragment, although it may not be able to open the starfall fragment, but it can stimulate the items inside to release a specific brilliance, through the light released can roughly judge the nature of the starfall fragment, this is the so-called "star appreciation".

Qin Zhan understood the principle and took the initiative to help her design a light wave comparison table to further simplify the astral technique, and then she went to help Zhang Naijing identify the starfall.

Zhang Naijing bought the starfall fragments with unknown attributes at a low price from the market, and after Qin Zhan's appraisal, he marked them with specific attributes and sold them at a high price.

In some starfall fragments, there are also remnants of spiritual veins, and such starfalls are particularly valuable. It can be buried in the spiritual field, so that the spiritual veins in it can slowly escape, thereby increasing the level of the spiritual field. If you don't understand the attributes of Starfall, if you extract the fire spirit vein and the gold spirit vein, it will destroy the nature of the spirit field.

Because of this, the starfall fragments that had been identified by Qin Zhan were very sought-after, and most of them were bought by the people of the Immortal Leaf Sect.

When the people of Xianye Gate saw the waist card on Zhang Naijing's body, they knew that he was from the Qin Palace, and they didn't dare to bully him.

In his free time, Qin Di called Zhang Naijing and Qin Zhan over and taught them the immortal texts of the space department.

"The immortal texts of time and space each have three thousand avenues, and each kind of avenue corresponds to an immortal text, and there are a total of 3,000 space-related immortal texts. Your skills are too weak now, and you can only learn a little bit of skin, which is good for improving your star appreciation skills. When you become immortals, these avenues will be of immeasurable value!"

Qin Zhan asked, "Brother, what is the use of learning these immortal texts well besides being used for identification?"

Qin Di said: "You can also crack the big array, no one can trap you, suddenly appear here, suddenly appear there, as soon as your mind moves, you can appear in different places." ”

"That's interesting. ”

"What about the Avenue of Time, can you go back in time?"

"You can go back, but you can't change history. ”

"Cut, you can't change history, what are you going to do back?"

Qin Di could only let out a wry smile.

On this day, the withered leaf master came again and asked, "Mr. Qin, have you broken through the Earth Immortal Cave Heaven?"

Qin Di listened to the tone of the other party's questioning, and knew that the Xianyin Sect had mastered the movements of the Qin Mansion, so he said, "That's right, I cracked an Earth Immortal Cave Heaven." ”

Master Withered Leaf was surprised and asked, "How did you crack it?"

Qin Di handed him a Void Breaking Talisman and said, "This is a good thing I bought from the domain, and I can use it to stimulate the magic circle in the cave heaven in order to crack the cave sky." ”

Master Withered Leaf couldn't understand it, and asked, "What kind of talisman is this?" Seeing that it flows with a rich immortal aura, it is obviously a high-level treasure talisman. ”

Qin Di smiled slightly: "You can take it back and try it." ”

The withered leaf master went back with the treasure talisman, and did not dare to test it alone, but took the treasure talisman to the bamboo leaf immortal.

The Bamboo Leaf Immortal was skeptical, took an Earth Immortal Cave Heaven, and then slapped the treasure talisman on it.

Then I saw that the Heaven of the Immortal Cave had a violent fluctuation, sometimes getting bigger and sometimes smaller, and the shape was also constantly twisting, from a circle to a square, and even a triangle.

Master Withered Leaves was dumbfounded, not knowing why this was happening.

The bamboo leaf fairy was surprised and delighted, and after a while, he suddenly slapped it in the corner of the cave!

The cave stopped changing, but a "gurgling" sound was heard, revealing a small portal!

"Haha, this is open? I've been thinking about it for many years, but I can't find the portal to get in and out, but I didn't expect it to be displayed by a treasure talisman!"

Master Withered Leaves was even more surprised: "Uncle Shi, how did you open it? Why didn't I see it clearly?"

Zhu Ye Immortal said: "Your skill is a little worse, and you can't see the changes in the law clearly, so you can't find the hidden portal." ”

"Uncle Shi, what kind of treasure talisman is this?"

"This seems to be the 'Void Key', its value is very great, but unfortunately it is only an eighth-order treasure talisman, if it reaches the immortal level, it can be said to be invaluable!"

"Void key? I've heard of it! There used to be a 'Heavenly Toad Sect', wasn't it someone who used the Void Key to crack the Great Array of the Protector Sect? As a result, the Heavenly Toad Sect suffered a heavy blow, and even the Earth Immortals in retreat fell!"

"I didn't expect Qin Di to have such a precious talisman!

"Uncle Shi, how much is this treasure talisman worth? It is not an immortal talisman after all, the core area of our Immortal Leaf Sect is protected by a first-order immortal array. ”

The Bamboo Leaf Immortal said: "Don't look at it as an eighth-order treasure talisman, it is worth no less than two Earth Immortal Pills." ”

The withered leaf immortal couldn't help but grit his teeth: "This Mr. Qin really has good things! Uncle Shi, it seems that this person has a very deep background!"

Zhu Ye sighed lightly: "Yes, there is a kind of person in the world, who specializes in cultivating the Great Dao of Time and Space, and the people who get this kind of inheritance seem to be rare. I don't know where Mr. Qin got the treasure talisman, but he actually knows such a master, which shows that the background is indeed very deep!"

"Do you want me to ask him?"

"Forget it, if you come from within the domain, it's useless to ask, across the chasm of heaven, it's difficult to cross the past, and there's no way to get a similar talisman. I will keep this treasure talisman first, and I can use it to open a few Earth Immortal Cave Heavens and strengthen the strength of this sect. ”

Since then, there have really been a few more caves in the Xianyin Sect, and there have been a few more places for the disciples to explore and cultivate.

For the Xiuzhen sect, the small world of the cave is of great significance, and one more cave heaven is equivalent to one more secret land, where you can collect spiritual materials, plant spiritual valleys, and do a lot of things. In the complete Earth Immortal Cave Heaven, there is at least one giant spirit vein, which can generate the best spirit stone, which can enhance the strength of the sect.

Xianye Sect originally had nine small worlds, and it was precisely because of the existence of these small worlds that a large number of disciples settled in Dayong City, otherwise they would be scattered to other cities due to the lack of cultivation resources. Now there are a few more small worlds, which was a great thing at the time.

It's a pity that that eighth-order talisman is not omnipotent, under its stimulation, the Bamboo Leaf Immortal Elder opened five cave heavens, and there is still nothing he can do about the rest of the cave heavens.

The Bamboo Leaf Immortal Elder couldn't help but sigh: "The level of the eighth-order treasure talisman is still a little lower! If it is an immortal talisman, it would be good! The Immortal Rank Void Key can open most of the Earth Immortal Cave Heaven." ”

However, there are very few people with spatial inheritance, and even fewer people can advance to the earth immortals and draw immortal talismans. Such people have never heard of it outside the territory at all!
