Chapter 741: Soul Gathering Jade Crystal

The expression of the city lord changed slightly, but no one noticed it. Everyone's attention was focused on the huge magic circle in the center of the square.

It can be said that everyone who came here was very interested in this mysterious city defense formation. There are also some rumors about the operation and changes of this magic circle, but I am afraid that only after seeing it with your own eyes can you know how it works.

But even if someone saw the change in the expression of the city lord at this time, they would not think that it was anything special. After all, Zuo Feng just changed his position, which seemed a bit abrupt, and it was normal for the city lord to have some thoughts about it.

In fact, the surprise in the heart of the city lord at this time was more than what he saw on the surface. Maybe the people present were not clear about this set of formations, but as the city lord and the person in charge of the villa, he knew many secrets.

In fact, the ancestors of the super families at that time only knew a little bit of the runes on the giant stone pillar. They studied a set of defensive magic circles based on the runes, which were the stone pillars built later, guiding the energy contained in the central stone pillar to form a protection.

But they themselves knew that for this huge central stone pillar, the power of the defensive array called out was only a drop in the bucket of the energy in the giant stone pillar.

However, after the defensive array was established, the super families fought for this place, and naturally no one had the leisure to continue studying the array. After the fight, of course, all parties compromised, but at that time this place had become the property of the empire, and other families were not allowed to come here casually.

Although every few years, each family can select outstanding children to come to the black crystal stone of the second competition to gain insights. It is very difficult to come to the center of this array, and it has almost never been allowed by the empire.

Later, this array was only controlled by the empire. The head of the empire would naturally not give up such a large treasure, and naturally invited some masters to come and study it.

After later research, the empire also discovered that it was possible to transform the original city defense array. After this transformation, the original city defense array has a new function, which is an alternative trial site.

However, such a formation consumes a lot of energy when it is in operation, especially the loss of materials such as magnetic spirit stone and beast core. Such loss cannot be used frequently even by the empire, so in recent years, the empire has not used this power much to help its elites train.

Others may not know much about the other training function of this formation, but as the city lord of Linshan County, he still knows some inside stories that others don’t know.

Especially the place where Zuo Feng is going now is the key to this training formation. Because the formation opened in the next competition is also extended from the rune power on the giant stone pillar, and the extended part is carved from the southeast corner. He believes that Zuo Feng should not know these things.

But since Zuo Feng can find that position accurately, it can also be seen that he is not simple, or it can be attributed to Zuo Feng’s sixth sense.

It was not until Zuo Feng sat cross-legged in the southeast corner of the giant pillar that the city lord looked away after a few more glances.

Yao Zhen and the other two contestants also looked up at Zuo Feng. They were naturally a little surprised by Zuo Feng’s choice.

The city lord said before that after the whole formation is running, the space inside the six stone pillars will be inside the formation. Everyone also chose the position in the center of the formation, which is also a safer choice.

Because near the edge of the formation, if the energy coverage is unstable, then once an accident occurs, the clone may be affected after being injured.

As for the location of the stone pillar, everyone can see that it is the place where the energy spreads out and is also the place where the energy is relatively concentrated. In this case, it is not wise to choose to be close to the stone pillar, so they are somewhat puzzled about Zuo Feng's choice to be close to the stone pillar.

At this moment, the whole stone pillar is divided into two parts. One part is the two people on the west side, both of whom are young people who participated in the first and second competitions before. The east side is Yao Zhen and Zuo Feng, but Zuo Feng's position is closer to the stone pillar.

Since Zuo Feng did not choose to go over and get together with the other two young people, the two people did not show any other emotions.

Seeing that everyone has chosen their respective positions, Su Lan and Zhong Lao also cast their eyes on the city lord. The city lord nodded slightly, then slowly took out a box from his arms and slowly opened it in front of everyone.

This is a wooden box, but there are many inlaid objects on the wooden box. If it is inlaid with some gems, perhaps this box will look very exquisite, but the wooden box is full of dark-colored stones, and the shapes of the stones are somewhat irregular.

However, everyone present is knowledgeable. After seeing the stone, they recognized it as a magnetic spirit stone at a glance. Although this kind of magnetic spirit stone is not as good as the one that Mr. Zhong took out before, it is already considered medium in quality.

The city lord looked at the wooden box in his hand with a gleam in his eyes, and then took out a large crystal core from it. Zuo Feng saw the crystal core at a glance. It should be the beast core of a third-level to fourth-level magic beast. Such a beast core is very valuable. I didn’t expect that it would be taken out and used here.

The city lord came to the bottom of one of the six stone pillars on the outside and slowly pressed the beast core in his hand into the groove where runes intersected on the pillar.

The groove was originally very shallow. If it was placed there normally, it would have fallen to the ground due to gravity. However, after the beast core was pressed on it, it seemed to be sucked in. When it was even half an inch close to the stone pillar, the beast core flew over on its own and merged with the stone pillar with a "click".

The city lord seemed to be used to it, but when he saw the beast core being sucked on the stone pillar, his eyelids twitched slightly with some pain.

Without stopping at all, the city lord turned around and walked towards the next stone pillar. He also took out a beast core, and the quality seemed to be better than the previous one. It was also placed on the stone pillar, and after being firmly absorbed by the stone pillar, the third beast core was also placed on the third pillar.

After arriving at the fourth stone pillar, it was originally thought that the city lord would continue to take out beast cores, but what he didn't expect was that the city lord actually broke off the magnetic spirit stone on the box and then placed the magnetic spirit stone on the stone pillar.

Everyone then understood that the magnetic spirit stone was not only placed on the wooden box to lock the energy of the beast core inside, but also a material needed to activate the formation.

When the immortal understood this in his heart, he saw an amazing scene happening at the place where the stone pillar and the magnetic spirit stone touched. The magnetic spirit stone was originally very irregular in shape, but after being adsorbed on the stone pillar, it slowly changed its appearance. In a moment, the magnetic spirit stone and the stone pillar merged into one, and even runes appeared on it.

If they hadn't seen it with their own eyes, everyone would not have believed that there was a groove there before. The next steps are the same as placing the beast core. The same magnetic spirit stone is placed on another stone pillar, and then it will slowly change its appearance and merge into one.

From beginning to end, everyone was observing silently, but no one said a word. Until the last magnetic spirit stone was placed, Su Lan's expression became gloomy.

Su Lan's voice was filled with suppressed dissatisfaction, and she slowly said, "This is what you said is valuable. I don't think you have any intention of living together. If that's the case, I think you..."

Su Lan's words were not finished, and they stopped abruptly, because he saw the city lord slowly take out a dark green crystal that looked like jade. The moment the crystal was taken out, the eyes of the people around gathered together, and at the same time, there were several sounds of inhaling violently.

The pupils of the two young men who participated in the competition had dilated at this time. If they had not been rational, they would have almost rushed over to see what was going on.

Zuo Feng's expression also changed slightly at this time, and he muttered to himself, "Gathering Spirit Jade Crystal. Could this be the legendary Gathering Spirit Jade Crystal? I didn't expect to see it here. It seems that the foundation of this city lord's mansion is really good."

The preciousness of this Gathering Spirit Jade Crystal is even far greater than the original ore of the magnetic spirit stone that Zhong Lao took out before. Not only is it rare and precious, but its value is also outrageous. Generally, a small family with one piece is likely to cause the disaster of extermination.

However, the city lord turned his head slightly, glanced at Su Lan who was still furious before, and turned his head coldly and ignored him, but quickly inserted the dark green crystal in his hand into the middle of the two stone pillars, which was also the edge of the formation.

When he inserted the spirit jade crystal into the ground, the surface of the two adjacent stone pillars immediately emitted a faint light, which was obviously being activated.

Then the city lord took out another piece of the same dark green spirit jade crystal, walked to the middle of the next intersection of the stones and inserted it into the ground, and the third stone pillar also lit up.

Seeing this scene, Su Lan also said with a slightly embarrassed face: "It seems that I misunderstood the city lord, so our transaction is still valid."

No one understood what this meant, only the city lord nodded slowly. At this time, he had taken out the fifth dark green spirit jade crystal, and Zuo Feng could feel that the energy contained in it seemed to be much higher than the previous four.

The spiritual power contained in this spirit-gathering jade crystal is almost equal to the total spiritual power of a warrior in the late stage of Qi Refining, and the spiritual power in it can be mobilized, which is also an important reason for its high value.

Once you have such a piece of spirit-gathering jade crystal, it is equivalent to having a mobile spiritual energy warehouse. Even if it is consumed in battle, there is no need to be afraid, which is also the reason why its value is high.
