casually touched a crystal nucleus that looked like an olive from his arms, and Zuo Feng couldn't help but look at it carefully, his eyes full of curiosity and joy.

The value of this thing itself Zuo Feng can't judge it specifically, but from the fleshy pain that the three elders showed when they took it out, it is obvious that the value of this thing should not be low.

Just inside the Yongjia Stone Castle, seeing that the Yong Fat Man had already laid out the basic formation of the Gathering Spirit at the tea time, and constantly adjusted the formation within half an hour, so that the Gathering Spirit Formation had four overall changes in a short period of time.

When the three elders saw that Yong Fat Man was arranging the most primitive formation, they had already completely believed in Zuo Feng's ability, and Zuo Feng's words were not bragging.

Because the arrangement of the formation is completely different from the normal depiction of the large array, it does not start from the most important point in the center. Instead, the fat man started from the outermost edge, which required an overall grasp of the formation, and the position of each rune was accurately grasped in his mind.

This way of arranging the formation was actually used by Zuo Feng when he arranged the formation before, but just now Zuo Feng just laid out the formation casually and didn't think too much about it.

The reason why Zuo Feng was able to start arranging the formation from the edge at will was because when he originally comprehended it, he also used the method of reverse deduction, so it seemed to be a very wonderful alternative arrangement of the formation, but it was extremely common for Zuo Feng to make it.

Yong Fat Man was secretly surprised when he saw it before, but his memory was amazing, and every step was memorized by him. At this time, the three elders inquired about the results, not only to show his mastery of the formation, but also to let Zuo Feng not underestimate himself, so he also arranged according to the gourd painting scoop.

Although the three elders had already mastered this basic formation, when they saw Yong Fatzi arranging it like this, they were still extremely shocked in their hearts, and they looked at it more carefully.

After that, Yong Fatzi was like fighting with Zuo Feng before, first adjusting one rune in the formation, and then quickly adjusting six or seven runes, so that the formation quickly stabilized.

By the time of the third adjustment, the three old men were already speechless with excitement, and the eyes of the three old men were already full of tears, and the excited three trembled unconsciously, and they didn't say anything for a long time.

It wasn't until the fat man dispersed the formation that the Great Elder gradually came back to his senses, his legs trembling slightly, and he was almost about to bend over and kowtow. But in the end, he was still a little sober, just clasped his fists and bowed slightly, and his voice was a little hoarse and solemnly thanked.

The other two elders didn't say anything, they also bowed in the same way, and looking at the appearance of the three of them at this time, there was no artificiality.

After that, the three old men kept saying, "I am grateful, I will definitely thank Shen Feng Xiaoyou", Zuo Feng listened and didn't care, but Yong Fat seemed to think of something, and suddenly asked the three old men to send something to Zuo Feng's body.

The reason is that Zuo Feng has not completely taught it yet, and he has not yet learned the rune changes of the other three formations, and Zuo Feng is leaving for the time being, and the Yong family needs to do their best to protect his safety.

After hearing this, the expressions of the three old men immediately changed, and the "heavy thanks" that they had kept saying before did not mention half a word, but said that the Yong family was willing to send someone to protect them, and they wanted to leave Zuo Feng in the Yong family for the time being.

The big change in the attitude of these three elders did not surprise Zuo Feng at all, but looking at the reactions of the three old men, it made him have some interest in the "self-defense thing" that Yong Fat Man said.

As for staying in the Yong family, it is impossible for Zuo Feng to agree, firstly, before choosing medicine, he still needs to find a way to improve his strength as soon as possible. Especially after getting the booklet introducing the crystal of the imperial array in the fourth layer, Zuo Feng was also more interested in that treasure, and the name of this competition medicine selection must also be obtained.

In addition, Zuo Feng hates restraint the most, especially this kind of house arrest to leave himself in the Yong family, which he can't tolerate even more. When he saw that the three elders put forward their opinions, they obviously had a somewhat consultative tone, and he understood that the three of them should have thoroughly investigated their own details.

With curiosity about "self-defense", Zuo Feng refused to stay in the Yongjia family, and at the same time refused to take people by his side.

After listening to this, Yong Fat Man kept adding oil and vinegar to the side, what "Zuo Feng is very important, there must be no loss, how can the life safety of the great benefactor be important." "Words like that.

In the end, the three elders had no choice but to take out the small crystal nuclei that Zuo Feng was holding in his hand from his body at this time.

With Zuo Feng's familiarity with various materials, he could see at a glance that this crystal nucleus should be made of beast cores, but now the appearance and the inside of the beast core have changed, so it is impossible to tell at a glance what grade of beast core it uses.

The core of the monster and demon beast itself is oval-shaped, and its surface will have a flat section like a vomiting crystal, and there will be countless reflective surfaces when it rotates in the sun.

However, the surface of the crystal nucleus in front of him has become extremely smooth, and the whole body is much smaller than the normal beast core, and the whole is in the shape of a flat olive, like two plates buckled together.

When Yong Fatzi took it from the three elders, he only briefly told Zuo Feng how to use it, but he didn't explain in detail what this thing was made of, so Zuo Feng knew it but didn't know why it was so he brought it out.

Seeing that it was getting farther and farther away from the Yongjia's stone castle, Zuo Feng was also driven by curiosity to take out one of the crystal nuclei.

At this time, on the palm of his hand, there were two crystal nuclei, one of which was green and the other was golden. It's just that on the surface, it's like a special spar that sparkles and shines, and there is nothing special about it.

Zuo Feng didn't dare to use his spiritual power to test it, because once this thing was activated with spiritual energy, it would quickly activate it.

This green crystal nucleus, according to Yong Fatzi, carries the power of siege, and the power of siege can temporarily trap the warrior in place without causing any damage to him.

Another yellow crystal nucleus, which carries a lot of destructive power, can cause damage to the warrior within a certain range.

According to Yong Fatzi's introduction, when using it, you need to pour the aura into it, and then throw it out as soon as possible. When Zuo Feng heard it, he almost rushed out the words "Yanjing Fire Thunder".

Although the method of use is exactly the same, the difference in size is completely different, the size of this crystal nucleus is like the thumb of an ordinary child, and it is not a problem to grab a dozen of them. But the eyes of fire and thunder can hold three or two in one hand, and it is almost the same.

Zuo Feng was curious, and looked around, but no one noticed him. In this Yong family's mansion, although there are also bright posts and secret posts, no one deliberately stares at them, I believe that this is also what the three elders have explained.

This is the biggest secret forbidden place of the Yong family, Zuo Feng has visited from the first floor to the top floor, and there is no secret in this Yong family that needs to be kept from Zuo Feng, but he is in the Yong family as if he is in a no-man's land.

As soon as the mind moved slightly, the telekinesis was sent out along the fingers, and almost in the blink of an eye, it was sent into the crystal nucleus in the hand. Although the spiritual power can have the ability to detect, he doesn't dare to use it now, which will only talk about the rapid activation of the crystal nucleus.

And the exploration of telekinesis is clearer and more careful than spiritual power, and the moment it is sent into the crystal nucleus, Zuo Feng's whole person is stunned.

"It turned out to be the basic formation of the Yong family, and the formation fit was not perfect, but it also allowed it to barely maintain stability, and the power contained in it was quite good. ”

After observing it, Zuo Feng withdrew his telekinesis from it. Although the method of making the crystal nucleus has not yet been figured out, the power contained in it, Zuo Feng, has figured it out.

The golden crystal nucleus has a powerful metallic power, and all of these forces are locked in the formation, and when all the formations in it are suddenly activated with spiritual power, the brittle metallic energy in it will be released.

Those metallicity should be mainly beast energy, only the formation has the component of human metallic spiritual power. The proximity of each other's attributes is the only way to stabilize it. And the strange shape of the crystal nucleus is the special shape formed by the fusion of the formations with each other, and the shape is almost completely attached to the internal formation.

Zuo Feng focused his attention on another crystal nucleus, and after using his mental power to check it, Zuo Feng clearly knew the doorway.

In this green crystal nucleus, the existence is naturally a wood-attribute beast energy, and the formation is also completely solidified, completely trapping the huge beast energy in it, waiting for the spiritual energy to be injected and completely activated.

Zuo Feng is very interested in this thing, if he is not in the Yong family at the moment, he really wants to stimulate it, see what power this crystal nucleus is, and why does Yong Fat Man say that it has the ability to save his life.

Zuo Feng put away the crystal nucleus in his hand with doubts, and walked towards the hall outside the mansion, and soon came to the outside of the hall. The two Su family warriors who came with him were meditating cross-legged in a corner of the hall at this time, and when Zuo Feng came, the two of them also opened their eyes together.

At this time, a warrior of the Yong family came from the side, came to Zuo Feng and bowed and said, "Elder Shen Feng, this is from the Yao family, he has been waiting for you for a long time, and the three elders said that they will bring him to see you when you come out." ”

Zuo Feng and the two martial artists of the Su family both turned their heads to look at the person from the Yao family in some surprise. The Nayong family bowed slightly, turned around and walked away without stopping at all.

The current Zuo Feng not only has the status of a guest of the Kang family, but also has the identity of a guest elder of the Yong family.
