Ling Zheng stared blankly at the pile of black and gray residues around the black ancient mirror, and was stunned for a while before picking up the only remaining yellow ring grass.

But just by looking at it, Ling Zheng felt like he had been electrocuted, and his hands trembled violently.

This yellow ring grass not only grows very well, the rhizome is strong, but what is even more incredible is that on the leaves of this yellow ring grass, there are seven white rings and three red rings!

Huanghuan grass is a spiritual grass, and it is actually very simple to identify its age, as long as you look at the number of rings on its leaves, and the color of the rings, you can know a rough idea.

For those under 10 years old, each year increases with a white ring on its leaves. After 10 years, with each additional 10 years, a white ring turns red.

In other words, the yellow ring grass in front of Ling Zheng now has been at least thirty years old.

How is this possible? The more than 30 yellow-ringed grasses just now are obviously only a white ring!

Ling Zheng stretched out his hand, touched the black ancient mirror that was still slightly warm, and then glanced at the black and gray residues around the black ancient mirror, and suddenly felt very familiar.

When the black ancient mirror was used to transform the waste pill into the spirit pill before, those waste pills that lost their essence didn't become this kind of thing?

Could it be that this black ancient mirror still has the ability to transform low-year medicinal materials into high-vintage medicinal materials?

For a while, Ling Zheng fell into a stupor, and his brain couldn't turn around. When he came back to his senses, he was pleasantly surprised.

According to the records of the "Chronicles of the Pills", many rare pills with wonderful effects, because the medicinal materials required for their refining must be hundreds or even thousands of copies, and in today's cultivation realm, although the refining methods of those rare pills are still there, they have not really appeared for thousands of years.

It is precisely because the value of those pills is really amazing, therefore, the price of the high-grade medicinal materials for refining those pills has also risen, and there are often some cultivators who fight for those medicinal materials of hundreds and previous years.

And with the Black Ancient Mirror, does it mean that he can easily obtain the high-grade medicinal materials that ordinary cultivators have to fight for even if they risk their lives?

Ling Zheng didn't want to sell those medicinal herbs, but he was going to use them for his own alchemy, he had been coveting the wonderful effects contained in those pills that were almost extinct for a long time, if he could refine those pills in a hurry, his cultivation speed would be greatly improved!

Although Ling Zheng has not yet learned alchemy, this thing can be learned just like making zuò talismans, and Ling Zheng feels that the speed at which he learns to make zuò talismans is very fast, and it should be much worse to learn alchemy.

Finally, Ling Zheng picked up the phantom demon bead that was dim at the moment and looked at it carefully.

Ling Zheng didn't have any ill feelings towards this kind of magic weapon in his heart, although it was said that ordinary magic weapons to improve spirituality must be at the cost of slaughtering other people's lives, but those were all things done by cultivators who mastered magic weapons, and there was nothing wrong with the magic weapons themselves, the fault was the people who used them.

The power of this Phantom Demon Bead was now comparable to that of a first-grade mid-rank spirit weapon, and Ling Zheng naturally had no intention of discarding it alive and throwing it aside. Regardless of whether it is a magic weapon or not, enhancing one's own strength is the most important thing.

As for how to enhance the power of this ghost bead, Ling Zheng also had an idea. In the future, when your cultivation is strong enough, you can just find a few damned cultivators who are full of evil and kill them, and at the same time eliminate harm for the world, you can also enhance the power of the Demon Bead, killing two birds with one stone, why not?

Thinking of this, Ling Zheng bit his finger and dripped his own blood onto the Demon Bead.

Suddenly, Ling Zheng felt that he had a sense of connection with this ghost bead. The Phantom Demon Bead flickered with purple light again, happily surrounding Ling Zheng's body, as if he was very excited when the Dancing Wind Sword was recognized by Ling Zheng.

However, after recognizing the Demon Bead, Ling Zheng received a message from the Demon Bead, and after reading the message, Ling Zheng's face became a little strange.

That piece of information turned out to be a fragmented Demon Dao Cultivation Inheritance that had been sealed in the Zài Demon Bead, called "Ghost Demon **".

Judging from that information, this ghost bead is only about one-tenth of the overall inheritance of "Ghost **", and it covers a series of strange spells like what kind of ghost retreat technique, ghost transformation technique, etc., Ling Zheng has never heard of.

Ling Zheng didn't take this Demon Dao cultivation inheritance to heart, he didn't plan to change to Demon Dao cultivation at all, so naturally he didn't have any thoughts about the other parts of this "Demon **".

With a thought in his mind, Ling Zheng also took the ghost bead into his body, and found that this ghost bead was the same as the dancing wind sword, and seemed to be very interested in the non-attribute spiritual power in his spiritual power magic ball, and it was also coiled around the spiritual power magic ball, absorbing the non-attribute spiritual power that escaped in the slightest.

After successfully recognizing the ghost bead, Ling Zheng cleaned up his cabin, and then lay comfortably on the bed, playing with the black ancient mirror in his hand.

In tonight's battle, although he had harvested a magic weapon that was comparable to a mid-level spiritual weapon, Ling Zheng felt that the biggest gain was the discovery of the ability of the black ancient mirror to transform low-grade medicinal materials into high-grade medicinal materials.

The ability of the Black Ancient Mirror to transform the waste pill into a high-quality spirit pill was already enough to defy the sky, and coupled with the ability to transform medicinal materials that had just been discovered, Ling Zheng felt that his future was bright.

He remembered the bottle of barrier-breaking pill he saw at the trade fair on the top of Baihe Mountain that day, and felt that it was a matter of time before he advanced to the Great Perfection of the Spirit Condensing Realm. But he knew very well that from the Great Perfection of the Spirit Condensation Realm to the Foundation Building Realm, it was a huge watershed on the road to cultivation. I don't know how many cultivators of the Great Perfection of the Spirit Condensation Realm have never been able to cross that hurdle in their entire lives.

Ling Zheng thought that he had worked so hard to advance to the third order of the Spirit Condensation Realm, and felt that after he cultivated the Great Perfection of the Spirit Condensing Realm, the process of advancing to the Foundation Building Realm would definitely not be so easy.

Therefore, at that time, the barrier breaking pill will be very important.

The refining technique of the barrier-breaking pill is not a secret, it is even recorded in the "Dan Yao Zhi", because Ling Zheng has read the entire "Dan Yao Zhi" thoroughly, so he naturally knows its refining techniques and prescriptions very well.

What is really difficult is the seven medicinal materials needed to refine the Barrier Breaking Pill, these seven medicinal materials have extremely strict requirements for the year, at least they must be more than two hundred years old.

But now, this kind of difficulty is nothing to Ling Zheng, as long as there are enough low-grade medicinal materials, he can get what he wants through the guò black ancient mirror.

"Hmm, it seems that I need to care more about the matter of medicinal herbs, I have to ask Wang An when I have time, he should be able to help." ”

After that, Ling Zheng fell into a deep sleep. The black ancient mirror that was carried in his arms seemed to understand his words, and exuded bursts of warmth.

Before dawn the next day, Ling Zheng was awakened by a sharp knock on the door.

"Brother, are you there, hurry up and open the door, there's something big!"

Ling Zheng heard that it was Wang An's voice, and got up to open the door, his face full of doubts.

Could it be that the death of Du Fei and Yu Cong was discovered so quickly?

Thinking of this, Ling Zheng's nerves tensed instantly.
