"The obsidian longan stone is naturally watery, but because it is hidden underneath all the year round, it has also absorbed a large amount of earth qi essence over tens of thousands of years, and it has become a very rare dual-attribute spiritual creature like water and soil......"

Tang Chuyang held a fist-sized black spar in his hand, black light was bright, like an eye, and explained the characteristics of spiritual materials to Cang Yao and Ya Xi, who were sitting cross-legged in front of him, obsidian dragon eye stone belonged to the eighth-order best material, and it was almost extinct in the entire continent.

The average obsidian dragon eye is only the size of a peanut grain, and it is recorded that the obsidian dragon eye can only form a black spar the size of a small thumb knuckle when it completely absorbs all the essence of a dragon, and then it will continue to grow in size with the length of time it nourishes itself.

According to the growth rate of the obsidian longan stone every three thousand years, the obsidian longan stone in Tang Chuyang's hand is the size of an adult's fist, not to mention more than 10,000 years old.

The obsidian longan stone is not difficult to refine, but refining it piece by piece has become the biggest problem that stumps Cangyao and Yaxi, for no other reason, this thing is a dual-attribute spiritual material, and the most pitiful thing is that these two attributes are still water attributes and earth attributes that restrain each other.

The method of refining the obsidian dragon's eye stone is also very simple, you only need to extract one of the two phases of the attribute of restraint, and the stone will immediately turn into a pile of powder full of aura, but only one of the two attributes can be left.

How to refine the obsidian dragon's eye stone while keeping the two attribute aura inside intact, this is the biggest problem for Cang Yao and Ya Xi.

Of course, it is impossible for Tang Chuyang to complete the refining of the Jun Fu by himself, although he now has the strength to refine the Jun Fu, he is only barely qualified. In terms of material refining alone, it takes a lot of Tang Chuyang's time and energy.

What the Tang family lacks most now is time, how could Tang Chuyang waste too much time on refining spiritual materials? has already looked at Cangyao and Lixi as coolies.

Moreover, the benefits of refining spiritual materials to Cang Yao and Ya Xi are also great. As the Tiger Clan, an ancient sub-god race, based on their own melee specialties and characteristics, refining weapons is a basic skill that almost every Tiger Clan member must master.

Cang Yao and Qi Xi were also very happy to assist Tang Chuyang in this regard, refining 10,000-year-old spiritual materials to test their refining skills, while also enriching their knowledge reserves of materials, and refining the best materials was also a great help for them to condense the true yuan and the original spirit.

This in itself is an extremely luxurious cultivation method, and even if others want to do this, they don't have the financial resources and resources.

The properties and formation process of the obsidian dragon's eye stone Cang Yao and Xuan Xi naturally knew that although Tang Chuyang was explaining the knowledge that both of them were familiar with. But Cang Yao and Qi Xi had no intention of stopping it, and the experience of getting along in the Heavenly God Ruins let the two know that Tang Chuyang's favorite thing was to start with the origin and characteristics of the materials.

In particular, Tang Chuyang's analysis and cognition of the formation process of materials is unique, and he can always give people a sense of brightness and a sense of openness, and he is accustomed to Tang Chuyang's teaching method.

"Big brother, sister-in-law. Tell me what you think, I've seen you do it a few times before, so you should have gained something, right?"

Let's talk about the origin, formation process and attribute characteristics of obsidian longan. Tang Chuyang began to ask, he is from modern times, and he is more accustomed to everyone debating with each other. Then find out where the problem is, and finally solve the problem in a targeted manner.

Cang Yao and Yan Xi also seemed to know Tang Chuyang's habits. Seeing Tang Chuyang asking, Cang Yao and Ya Xi nodded to each other. Ya Xi said with a little distress:

"We've tried to add attributes to prevent the two properties from collapsing due to violent conflicts, whether it's metal, wood, or fire.

Once it is added, it is stable at the beginning, but once the material starts to melt, it will collapse instantly, and it will not be able to alleviate it at all......"

"That's for sure!"

Tang Chuyang nodded, adding attributes to alleviate the conflict of dual-attribute materials This method is one of the basic skills that the existing refining room in the Five Elements Continent must master, especially when it comes to dual-attribute materials with similar attributes, this method is the most commonly applied.

"According to the theory of the five elements, it is most appropriate to add wood attributes to the dual attributes of water and soil, because the wood attributes do not have any direct connection with the first two, I think, big brother and sister-in-law, you must do the same!"

"That's right, we added the wood attribute of the same genus to it, and it was relatively smooth at first, and the two attributes of water and soil separated by the wood attribute were fine, but when we started refining, for some reason, the three attributes of water, wood and earth were completely chaotic, and they couldn't be stabilized at all!"

When Cang Yao said this, the corners of his mouth twitched constantly, as if he was extremely depressed about this abnormal phenomenon, and he couldn't figure out what was wrong with it.

Tang Chuyang smiled when he heard this, although his refining theory was extremely rich, there were very few opportunities to really do it in his previous life, and he couldn't do it without doing it himself, and he couldn't let Tang Chuyang thoroughly explain the reason for the connection.

Therefore, Tang Chuyang's way of lecturing Cang Yao and Lixi was very simple, and even a little irresponsible, he did it himself, and then let Cang Yao and Lixi see it by themselves and understand it by themselves, this is Tang Chuyang's way of teaching students.

This is also a helpless thing, Tang Chuyang himself is just a rookie in refining, after all, the theories in his head are all seen from books, and the conditions of the Tang family in the past did not support him with the resources and financial resources to integrate time and theory.

There are some things he understands, and he also knows what the most critical factors are, but to let Tang Chuyang clearly explain the stakes, this is absolutely impossible for him to do before practice.

"In this way, I will refine it myself once, and the eldest brother and sister-in-law will observe it carefully, and then you two will go back and slowly comprehend it......"

As Tang Chuyang spoke, he released the Yuan Shen Perception, shrouded the obsidian dragon eye stone in his hand, and after trying his best to line up the two attributes of water and soil to both sides, Tang Chuyang raised and fell with lightning speed, and the dragon eye stone in his hand was cut in half by him.

"Well, okay......"

Tang Chuyang exhaled with a sweat, it was still not good to cultivate too low, it was just a matter of discharging the two attributes, and it actually consumed most of the true yuan in his body, which had to be put on Cang Yao and Lixi, I am afraid that this problem can be solved by eating and drinking.

"This, that's good?!"

Cang Yao and Qi Xi opened their mouths in surprise, they thought that Tang Chuyang might have mastered a more superb refining technique of adding control attributes, who knew that people didn't have the mind to add attributes at all, and they would go straight down with a knife, and the materials that would kill the two of them would be solved?

Cangyao picked up the two halves of the longan stone that had been cut a little unbelievingly, released the Yuan Shen perception and sensed it slightly, and a slightly suspicious face suddenly turned into a stunned face, and said in disbelief:

"This, how can this be?!?!! is really separated" (to be continued......
