The rich spiritual power spread throughout the secret room in an instant, and Chen Fei directly began to cultivate the Zhen Firmament, as well as the secondary rules of the remaining two kinds of water.

The Heavenly Frost Yu Divine Technique had already been cultivated to the Great Perfection Realm, and Chen Fei now had no other exercises in his hands to cultivate, so the two cultivation positions vacated were all given to the secondary rules of water.

This Xuanguang Stone has almost complete secondary rules, and through the observation just now, if the number of Xuanguang Stones is large enough, it can directly arrange a formation similar to the Spirit Gathering Array.

At that time, with the passage of time, depending on the number of Xuanguang Stones, a small Xuanguang Pool will appear.

It must not be compared with the genuine Xuanguang Pool, after all, the Xian clan has arranged the Xuanguang Pool for I don't know how many thousands of years, and today's Xuanguang Pool is even increasing the number of Xuanguang Stones by itself.

Otherwise, the Xian clan would not have taken the Xuanguang Stone as their heart and gave a piece to all the Open Heaven Realm people present at that time.

Chen Fei didn't have so many Xuanguang stones, and he didn't have so much time to arrange a small Xuanguang pool, and the shattered Xuanguang stone was the fastest way to realize it.

Of course, if it doesn't crumble, there are actually other uses, but none of them are suitable for Chen Fei.

Dozens of breaths of time passed in a blink of an eye, and the spiritual machine in the secret room began to return to normal.

Chen Fei's eyes opened, sensing the changes in the proficiency of the Zhen Firmament and the secondary rules of water.

This Xuanguang Stone, the spiritual machine triggered after it was shattered, was roughly equivalent to one percent of the spiritual essence in the early stage of the Open Heaven Realm.

This effect is less than Chen Fei imagined.

Of course, the value of Xuanguang Stone cannot be measured in such a way, after all, Chen Fei is only seeking the spiritual opportunity, but the role of Xuanguang Stone is not only this.

The spirit essence in the early stage of the Open Heaven Realm can also be used in many very useful places, but Chen Fei chose the most simple and crude way to use it.

But no matter what the true value of the early stage of the Open Heaven Realm spirit essence or the Xuanguang Stone is, now in Chen Fei's hands, it is such a way to measure.

After all, this method is the fastest way to improve Chen Fei's cultivation realm.

Chen Fei shattered the remaining half of the Xuanguang Stone in his hand, and a weaker spiritual opportunity descended than just now, Chen Fei closed his eyes and began to cultivate.

After more than a dozen breaths passed, Chen Fei exhaled a breath of turbidity, and the secondary rules of the firmament and water improved again, but Chen Fei was not satisfied.

Chen Fei got up, left the secret room, and walked to the courtyard where the Xuan clan was.

It is impossible to get those Xuanguang stones from the hands of the Xian clan in a short period of time, but at this moment, in the hands of other Open Heaven Realms in Xian City, everyone has a Xuanguang stone.

Chen Fei could use the medium-grade Yuan Crystal and the seventh-order spiritual materials to exchange these Xuanguang Stones from the hands of these Heaven Opening Realms.

As soon as Chen Fei came to the gate of the Xuan courtyard, the gate of the courtyard automatically opened, and Li Song's figure appeared and arched his hand at Chen Fei.

"Something to ask for." Chen Fei also arched his hand.

"Brother Chen is polite, between you and me, everything can be discussed, why not ask for a word." Li Song welcomed Chen Fei into the courtyard.

"Can the Xuanguang Stone in everyone's hands be useful? I am willing to exchange three thousand medium-grade Yuan Jing for a Xuanguang stone. Chen Fei looked at the Open Heaven Realm of several Xuan clans in the courtyard and said in a low voice.

Three thousand medium-grade Yuan Crystals, you can already buy an ordinary low-grade Open Heaven Treasure Treasure, most of the early stage of the Open Heaven Realm, plus the low-grade Open Heaven Treasure in your hand, it is estimated that there are only 10,000 medium-grade Yuan Crystals.

In the task hall just now, the task reward in the early stage of the Sancheng Open Heaven Realm was half a Xuanguang stone, but this was the result of the Xian clan's greatly increased reward.

Therefore, Chen Fei exchanged three thousand medium-grade yuan crystals for a Xuanguang stone, which can definitely be regarded as full of sincerity.

After all, in the hands of other Open Heaven Realms, Xuanguang Pool could not be transformed into his own combat power immediately like Chen Fei.

When it comes to the Seventh-Order Open Heaven Realm, except for a very small number of legendary Heavenly Materials and Earth Treasures, there are almost no spiritual materials that can make the progress of the Open Heaven Realm instantaneous, and they all need to rely on time to exchange.

Hearing Chen Fei's words, the Xuan Clan's Open Heaven Realm was stunned for a moment, they saw Chen Fei coming over solemnly, and they thought they were going to say something, but they didn't expect that they wanted to buy Xuanguang Stone.

Xuanguang Stone has been studied by them just now, it is indeed a good thing, but it is impossible to immediately improve the cultivation, the value is slightly higher than that of the seventh-order lower-grade spiritual material, but it has not reached the position of the seventh-order middle-grade spiritual material.

Three thousand medium-grade Yuanjing is a Xuanguang stone, but they are cost-effective.

"If Brother Chen needs Xuanguang Stone, we will give it to you directly, it's like this, and you don't need to deliberately exchange it for medium-grade Yuan Jing." Li Song said with a smile.

If it is a normal time, even if it is an alliance relationship, it must be mutually beneficial, and it is impossible to give anything directly for nothing, which is also not conducive to the relationship between alliances.

But now that the Xuanling Domain is about to be destroyed, the most important thing is to save his life.

The Xuanguang Stone is in their hands, and now it can't have any effect, if Chen Fei can improve some cultivation, then give it directly to Chen Fei.

Chen Fei has become stronger, if they encounter danger, Chen Fei has spare strength, for the sake of the alliance, presumably Chen Fei will not stand idly by.

"I have some Yuan Crystals in my hands, so I don't have to do this, but if you don't need Yuan Crystals, I also have some healing elixirs, which should be of greater help to you."

When Chen Fei heard Li Song's words, he couldn't help but smile on his face, then thought for a while, and took out some healing pills from Zangyuan Zhong.

Yesterday, when I was preparing to attack the Rain Clan, the price of the pills related to healing injuries in the Xuanling Domain skyrocketed, after all, if you want to fight, injuries are inevitable, and the demand for wound medicine will naturally increase greatly.

To this day, the value of this wound medicine continues to soar.

"Brother Chen, you really don't have to be like this, we have the medicine in the Xuan clan." Li Song wanted it in his heart, but he still excused himself.

At this juncture, if you don't open the Heaven Realm, you will dislike the healing elixir in your hand, after all, you don't know what will happen here in the end.

There is such a thing as wound medicine, and the more the better.

"I have more medicine for injuries, and the Terrans need to fight for me as an Open Heaven Realm, and I don't need so much medicine for injuries." Chen Fei said with a smile.

In fact, Chen Fei is the least needed for injury medicine, seeing that the gods are immortal and the sky is so that Chen Fei will either not be injured, and if he is injured, he will have broken through all defenses and fallen into a state of near death.

At that time, the healing elixir didn't have much effect.

Therefore, none of the wound medicines in Chen Fei's hands were bought by Chen Fei himself, they were all obtained from the collections of Liao Xia's Open Heaven Realm, but he hadn't had time to realize them yet.

Li Song excused himself a few times, and finally accepted the wound medicine in Chen Fei's hand, and handed over eleven pieces of Xuanguang Stone to Chen Fei.

"Farewell!"

Chen Fei arched his hand at Li Song a few times, turned to leave, and walked around Xiancheng at the same time, wanting to exchange for more Xuanguang Stones.

After just walking for a while, Chen Fei had to stop.

At this moment, the other races in Xiancheng Open Heaven Realm are all meditating in their respective courtyards to adjust their state, and there are no other Open Heaven Realms to be seen on the streets of Xian City.

At this moment, he went directly to other courtyards to knock on the door, saying that he wanted to change the Xuanguang Stone, which was somewhat provocative, after all, Chen Fei was not familiar with most of the Open Heaven Realm in the Xuanling Domain.

The Rain Clan's army is coming, if there is still plenty of time, then the provocation will be provocative, as long as Chen Fei shows enough money in the end, presumably the other party can understand Chen Fei's approach.

Chen Fei thought for a moment, returned to the courtyard where he was, and began to shatter the Xuanguang Stone in his hand.

The Xuanguang Stones in the hands of the other Open Heaven Realm could only wait for the Rain Clan's attack to come to an end before Chen Fei had a chance to exchange it.

Eleven pieces of Xuanguang Stones, which are equivalent to more than one Enlightening Heaven Realm Early Stage Spiritual Essence, the cultivation effect is still quite good, at least compared to Chen Fei's use of Qiling Pill, the effect will be better, and the cost performance is also higher, but it is a pity that there are too few Xuanguang Stones in his hand.

After a while, Chen Fei opened his eyes, the fourth secondary rule of water in his body had already reached a position close to eighty percent, and with more than ten or twenty Xuanguang stones, he could complete the cultivation of this secondary rule of water.

Because just now it was the secondary rule of the two water of the initiate, and the secondary rule of the fifth water reached the position of close to 20%.

Therefore, if there were enough Xuanguang Stones, Chen Fei could really break through to the late stage of the Open Heaven Realm in a short period of time, and even that Xuanguang Pool, Chen Fei would not have to enter it again.

There are hundreds of Alien Open Heaven Realm in the mission hall just now, and this is hundreds of Xuanguang Stones.

Not to mention buying them all, there are not so many middle-grade Yuanjing in Chen Fei's hands, but as long as he buys two or three hundred yuan, it is enough for Chen Fei's cultivation to improve by leaps and bounds.

"Bell!"

Chen Fei was sorting out what he had gained, when suddenly a loud voice resounded throughout Xiancheng, and all the Open Heaven Realms appeared in mid-air.

"The Rain Clan is out!"

A huge bronze mirror appeared in the sky above Xiancheng, shining in the direction of the Rain Clan's territory.

The next moment, a light curtain appeared in mid-air, revealing the general mountains, rivers, lakes and seas of the Xuanling Domain, and at this moment, there was a cloud of black ink pouring out from the territory of the Rain Clan, infecting the Xuanling Domain.

The existence of the Xuanling Barrier cannot completely stop the power of the Heart Realm, and wherever the Rain Clan appears at this moment, the power of the Heart Realm will follow.

At most, the Xuanling Barrier is to make the power of the Heart Realm unable to completely diffuse into the entire Xuanling Domain.

On the light curtain transformed by the bronze mirror, the Rain Clan's army suddenly divided into three after flying for a million miles, one army rushed to the position of the Yan Clan, another directly attacked the Xian Clan, and the remaining small one began to clear the rest of the Xuanling Domain.

This Rain Clan really didn't let go of those cultivators who were hiding in other places.

Seeing this scene, the expressions of all the Open Heaven Realms in the Xian City became solemn, and the same was true of the Open Heaven Realm and the Creation Realm of the Xian Clan.

In fact, no matter which eighth-order race the Rain Clan pounced on, they would have to face it, but the feeling of the Rain Clan's direct rush still made the hearts of the cultivators present tremble.

"Please!"

Shi Jianzhu's voice sounded, and then a shield wrapped the entire Xian City, and the formation reached the eighth order, which was already a world of its own, even if there was no heaven and earth vitality in the outside world, it could operate on its own for a very long time.

"Stubborn, give you a chance, you don't know how to cherish it, you deserve to die here!"

The cold voice suddenly spread throughout Xiancheng, and at some point, it was already pitch black outside Xiancheng. (End of chapter)
