And Zhou Feng estimated that he had broken through the level, and the Hanhai Tidal Heart Method had to be as big as the fifth level, so he had to speed up his cultivation.

It is obviously inappropriate to always go to the Tianwu Secret Realm, mainly because Zhou Feng's strength has exceeded the upper limit of what the Tianwu Secret Realm can bear, and it doesn't matter if you go in once or twice once in a while, but if there are too many times, it is estimated that it will likely cause the space of the entire Tianwu Secret Realm to collapse.

Although the Nine Turns Yin Yang Stone Stalactites are also said to be the Heaven and Earth Spirit Spring, they are extremely precious materials like the earth vein gold liquid that Zhou Feng has seen, and the flesh and bones of the living dead may be exaggerated a little, but they definitely have the miraculous effect of an extremely artifact, but compared to those treasures, it seems a little inferior.

It is not surprising that in that ancient era, all kinds of resources were still very abundant, and correspondingly, all kinds of blades and treasures were scarce, which caused the market of these treasures to be priceless at that time, and no one was willing to spend a high price to buy them.

It's just that now, the situation is completely different, all kinds of resources have become scarce, and consumable things are used a little less, such is the case with the Nine Turns Yin Yang Stone Stalactite, and it is estimated that there is only so little left.

The child of the Nine Turns Yin Yang Stone Stalactite is just a rare elixir for others, but it is completely different for Zhou Feng, it represents the redemption of life again and again, and it is also the most suitable for Zhou Feng to use.

When Zhou Feng's hand gradually approached the disc, the blocking power gradually increased a lot, but the red light on Zhou Feng's hand flickered even faster, releasing a faint halo to offset the blocking power brought by the formation to Zhou Feng.

Finally, the hard work paid off......

When Zhou Feng touched the disc, he suddenly felt a cold chill circling around Zhou Feng's body along Zhou Feng's arm, which immediately made Zhou Feng feel refreshed all over his body.

"Old ghost, be careful......"

Although this disc had already been touched, just in case, Zhou Feng still reminded Li Fangyuan in advance, so as not to avoid accidents in time.

Airplanes~~

Zhou Feng's wrist flicked slightly, and the disc was immediately lifted from the box, Zhou Feng immediately felt its heaviness, and one arm was actually a little struggling.

Since the dragon qi refining body, Zhou Feng's strength is not ordinarily large, you must know that Zhou Feng grabbed the huge body of the evil dragon and then forcibly pulled it back, that power is definitely comparable to the dragon clan.

But even so, this disc that didn't look very big made Zhou Feng feel struggling, so its weight could be seen.

It's just that after the treasure left the box, that formation was immediately activated, and Zhou Feng more clearly perceived the huge vitality fluctuations brought about by this formation and the chain formation, and a strong man like Rao couldn't help frowning.

"Don't worry, it's okay!"

However, Li Fangyuan looked very calm, and pointed to the bursts of red light coming out of Zhou Feng's hand, and at this time he was also agitated, don't look at it as if it was very inconspicuous, but it was actually able to compete with the vitality fluctuations released by so many chain formations, and ...... In the end, he won.

"Whew~~ It's finally a success!"

When the red light battle chain formation finally won the victory, Zhou Feng was also able to get the disc and the nine-turn yin-yang stone stalactite on it out, this wipe is a long sigh of relief, the process just now was too thrilling, Zhou Feng's heart almost always fell in his throat, for fear that their guess would be wrong, then it would be really troublesome.

However, there is one thing, Zhou Feng can be regarded as the final confirmation this time, that is, the treasures in this treasure vault are not able to move at will, look at it, as long as you accidentally look at it from a safe distance, then there is no problem at all.

But if it's the opposite, and you want to touch, touch, or even take it, then the situation is completely different.

Such a strong fluctuation of vitality, once it erupted, he and Li Fangyuan's two small bodies really might not be able to resist tossing a few times, not to mention that the formations in the treasure cave were all interlocked, if one formation was touched, there would be several, dozens, or even dozens of formation cups triggered, so how terrifying the power of the eruption was, this was beyond Zhou Feng's imagination.

Even Zhou Feng didn't doubt that if it really happened like that, the peak powerhouse would only be the life of cannon fodder if he threw it in, maybe the powerhouse of the Holy Rank Realm would be able to mix it up.

It's just that this world is still where there are so many Saint-level realm powerhouses, and outside of the Outer Heaven and the mysterious Sky City, just this continent, the Saint-level realm powerhouses have not been able to exceed the number of two palms.

"If I'm not mistaken, this disc should be made of the 10,000-year-old cold iron from the deep sea...... No, it's a natural formation, the power of nature, it's really magical! ”

Li Fangyuan looked around this disc several times, tried it many times, and finally gave a vague judgment, although he himself was not sure, but it should be about the same.

Ten thousand years of cold iron, is in the deepest part of the deep sea bottom of the cold spring sea eye breeding ten thousand years of fine iron, years of suffering from the baptism of the cold spring, the cold is absolutely quite amazing.

Zhou Feng had experienced the baptism of the cold spring of Zhu Tianfeng, but the moment he came into contact just now, he couldn't help but be frozen a little stiff, but fortunately, Zhou Feng had the strength of Xuan Ice in his body, and it quickly merged with this chill, not only did it not cause any trouble to Zhou Feng, but it made Zhou Feng profit a lot because of it.

For the masters of cultivating the ice system Yuan Force, the effect is still very good, if it can be created into a divine soldier, it is definitely a sword that surpasses the scope of ordinary people-level divine weapons, and even a swordsmith with an extremely superb memory can create a divine soldier.

Of course, this premise is that an extremely powerful beast soul must be prepared as a machine spirit.

It's just that this doesn't have much to do with Zhou Feng, he not only uses such a large piece of Wannian Cold Essence Iron in his hand, this thing is born with the effect of breeding nine-turn yin-yang stone stalactites, otherwise, these nine-turn yin-yang stone stalactites have already been taken out, how can there still be so many left, and it is as fresh as ever, this is all caused by the cold of this piece of ten-thousand-year cold essence iron.

"Sure enough, it's a treasure of heaven and earth, and the energy contained in it is so terrifying......"

Putting aside the ten thousand years of cold essence iron, the attention of the two people was focused on the number of nine-turn yin-yang stone stalactites in front of them, which was not very large, and the two pairs of eyes widened, and carefully looked at these nine-turn yin-yang stone stalactites.

But judging from the appearance, it is obvious that the nine-turn yin-yang stone stalactites are not so good-looking, and even some stone powder or stone scale and the like can be faintly seen falling into it, which makes people feel uncomfortable when they look at it.

When facing these Nine Turns Yin Yang Stone Stalactites like this, Rao is Li Fangyuan, who was not very interested in this before, couldn't help but be shocked by the terrifying heaven and earth aura contained in it.

"Presumably it is the effect of this piece of cold essence iron, which has enhanced the effect of these nine-turn yin-yang stone stalactites a lot, I have seen the leyline gold liquid, but it is obviously not as good as the nine-turn yin-yang stone stalactites in front of me!"

Zhou Feng shook his head and said, this Nine Turns Yin Yang Stone Stalactite is very strong, no wonder it can be specially placed in this treasure house, you must know that even the existence of Shenmu Wang Ding, which can be called an artifact, is also thrown outside.

"It seems that this piece of cold essence iron is not an ordinary mortal thing......"

Wanzai cold iron is just a simple general term, in fact, it is also such a Wanzai cold iron, the difference is also very big, a little just a little ordinary top-quality ore, and some are very precious treasures, such as this piece in front of you, it is obviously an extremely high-quality goods.

"Zhou boy, you said that the reason why this nine-turn yin-yang stone stalactite is placed here, in fact, the real value is not it, but this piece of ten thousand years of cold essence iron?"

While pondering, Li Fangyuan suddenly asked with a somewhat strange face.

"Well, it's really possible!"

Not to mention, if you look at it in this way, it seems that Li Fangyuan's guess is more likely, although the value of the Nine Turns Yin Yang Stone Stalactite is not low, but compared to the treasures here, it is a little too low-grade, but if it is placed in this treasure house, then it is likely that its value can be compared with other treasures, it is entirely because of the value of the piece of cold essence iron below, and it is just a coincidence.

"Why don't we give it a try......"

With this piece of cold essence iron in place, the two of them were a little moved, but it was impossible to confirm whether it was as they had guessed, so Li Fangyuan couldn't help but propose after thinking about it.

"Then give it a try."

Zhou Feng pondered for a while, and felt that this was also reasonable, there was a treasure but he didn't know where its miraculous effect was, this was really an insult to this kind of treasure, it was simply destroying the heavens, not to mention that this treasure was obtained from the treasure house of the Xuanwu Holy Palace, one of the four holy palaces in ancient times and at the peak of human martial arts.

It is absolutely impossible to be weak to be able to place it with some other artifact-like treasures, otherwise it would not even have the qualifications to enter this door of the treasure cave, let alone specially placed a box for it, although the location of this box is not very conspicuous, but being able to enter here is itself a recognition of honor and strength.

After thinking about it, Zhou Feng took out a purple blood Bodhi from his body, since that time after the sacrifice of the Witch Venerable Ceremony of the Barbarian Witch Palace, Zhou Feng deliberately picked a few more and carried them with him when he went back to Zhutian Peak, just in case of emergency.
