What Chu He thought was leaning towards the Heavenly Star Sect. The Celestial Star Sect was powerful, one of the best in the Southern Continent, and the area it covered was very wide.

Although the Southern Sword Sect also has a long tradition on the Tiannan side, it was not a big sect 10,000 years ago, and it could only be in a corner of the country at that time. Most of the resources of the Tiannan and Extreme South regions were still in the hands of the Heavenly Star Sect.

I don't know how long the Dao Heavenly Star Sect has been operating in the Tiannan Domain, and whether it has extended its tentacles to the Black Sea, but if it is arranged in the Secret Water Realm, it is not impossible.

After all, this kind of remote place where water and fire coexist is rare in the world, and if it can be used properly, it can do a lot of things, not only alchemy and refining. In particular, it is suitable for monks like Chu River, who are spirits of both fire and water, to retreat.

Falling to the ground, Chu He was about to jump off Xuanwen's back.

"Master, be careful, the geomagnetic force here is not trivial. Xuanwen reminded at this time.

"Huh?" Chu He realized that the raging magma river and the narrow clearing were covered with a faint layer of brilliance, and from time to time there were five lights passing by.

Before, due to the fierce fire on the ground, the entire bottom of the pit was red and dazzling, and Chu He did not find that layer of geomagnetic yuan light for a while. If it weren't for Xuanwen's timely reminder, I was afraid that there would be a clown.

"The geomagnetic element light at the entrance is still weak, and if it goes down to it, it will increase exponentially. Xuanwen continued.

If there is no geomagnetic element light in it, this strange scene will not be so stable, and it will have long been agitated and chaotic.

The power of the Yuan Magnet, coupled with the agitation of water and fire, gave birth to visions, including the wind blade of the genus Xìng. It's just that I don't know how to go down, and if you go inside, you will see what kind of strange Gangyuan you will see.

Chu He prepared a little, and stimulated all the power of the treasure clothes and armor on his body, and then jumped up in the air and went straight to the entrance. And Xuanwen saw that Chu He had made up his mind. He didn't say anything, and immediately rushed to open the way.

Anyway, even if you meet the terrifying Ice and Fire Python, with your own cultivation, you can barely keep it safe. At that time, the exit will be.

The power of the earth and fire here is extremely strong. Maybe it's because of the abundant accumulation, I saw a heavy golden sè flame, like boiling boiling water, and the crimson sè ground fire of the lower level. The status here is limited to the surrounding area.

Xuanwen has magical powers, and I saw that his whole body was covered with bursts of silver-white sè runes, and his whole body was covered with a layer of silver-white sè brilliance, which kept circulating. Chu He just glanced at it twice, and then felt a little dizzy.

There must be layers of high-level talisman arrays to support it, so that even the eyes can be involved. It is equivalent to a puppet of Yuanying's middle-level cultivation, and the layers of magic circles imprinted on its body are at least ten or twenty or more high-level.

He didn't have a deep attainment in the Yuan Shen Realm, and he had extraordinary grandmaster-level strength on the puppet, so it was difficult to create such a puppet.

For a long time on the market, the six-armed silver guard could not be bought with spirit stones, and it only had a very close relationship with the Xuanji Sect. and pay a lot of money to get one from it.

And Xuanwen's master actually gave a broken four-armed silver guard to his disciple, which shows that his master's status in Xuanji Sect is also unusual. It could be the top few, if not, it's pretty much the same.

With such an identity and status, Xuan Tianyi is still able to do it, is he brainless or too arrogant? Or is he ruthless. Stop at nothing. However, there is a reason. That Senior Sister Zhang Wanran should have played a very important role.

Thinking about it for a flash, the thickness of the cold and flame made Chu He a spirit, and he put all his heart and soul on this journey of exploration.

Although I had the experience of walking through the earth fire before, it was obvious that the pressure I faced this time was much greater.

Although the amount of heavy water hanging down is small, it is still a gathering of water, and it can still easily break away the scorching magma and golden earth fire, and go deep inside, not knowing where the end is.

After going a little deeper, the Chu River finally discovered: how the heavy water mythril was formed, only to see that the heavy water broke through the heavy magma and the golden earth fire, in this process, perhaps because it was in a special state, it was fused with some silver objects in the magma, and then continued to undergo the calcination of the golden earth fire in the descent.

And the more it goes on, the more the geomagnetic element force increases, and some white sè earth fire appears. These heavy water mythril fused with Mithril, under the action of the geomagnetic element force and the white sè earth fire, finally stripped of impurities again and condensed into heavy water Mithril with extremely high purity.

"Master, be careful, those white sè earth fires are terrifying, the light protection of the ordinary Yuan Ying Zhenjun can be broken, and it is best not to collect the heavy water Mithril here, everything goes down and then takes its time. Xuanwen reminded at this time, and at the same time, he sent a cold light, which made the various pressures faced by Chu He much easier.

The golden sè ground fire is a flame that can threaten the real people of the Yuan Dan Realm, and the white sè ground fire can hurt the Yuan Ying Zhenjun even more. Chu He only has the cultivation of the upper rank of Yuan Dan, although the true Yuan jīng is pure, and he also has the cold and flame sword intent to protect the body, but in the home field of this earth fire, it still seems a little difficult.

The most troublesome thing for him is the geomagnetic element force, compared to those eruptions in the Heavenly Star Divine Palace, it is much more stable here, but because of the long accumulation, it is far superior in strength. This kind of majestic geomagnetic element force greatly restricts his activities in it, and the pervasive geomagnetic element force is really annoying.

No wonder, on the data, the collection of heavy water Mithril can only be carried out in an area with a slight white fire, and it cannot be lowered into it. Even so, it is necessary to apply a low-grade spirit treasure-level armor, and with the extreme cold and light protection, you can move in it with confidence.

The clothes of the low-grade spirit treasure are the Blue Ice Spirit Armor, which is tailor-made by the Xuanji Sect for everyone who has entered the secret realm, and it is used in this area where the earth is churning, and it is an excellent protection object. Since its composition is mainly thousand-year-old ice crystals and fourth-grade Xuanbai jade, which are not within the five elements, it also has a lot of effect in isolating and resisting the geomagnetic elemental force.

However, Chu He didn't want to use the Blue Ice Spirit Armor so soon, and the current situation could still be kept safe under the protection of Xuanwen. Go down to the innermost, if you meet that ice and fire python, you will have to have a fierce battle, and Xuanwen will not be able to take care of himself at that time, and it is just right to use it for self-protection.

With the support of Xuanwen, he carefully slowed down his speed all the way, and soon passed through a distance of hundreds of zhang and arrived at the depths of the earth fire.

Chu He didn't expect that although the entrance was full of magma and many grades of earth fire, there was a different kind of space when it fell below.

Below is an earth fire vein, a very wide earth fire vein, more than 100 zhang in size. The magma that fell from the entrance was like a "rumbling" waterfall of fire, which was injected into the veins of earth fire.

The geomagnetic force here is extremely fierce, and with the support of Xuanwen, Chu He also feels tight and uncomfortable. If it weren't for Xuanwen's help, I'm afraid it would be a little difficult to act.

"There's a lot of heavy water Mithril down here, so I'll go down and clean it up for my master. Xuanwen said.

It can be seen that he is also a straight-hearted spleen, and after he returned to the seat of Chu He, he did his best in everything.

Thinking of this, Chu He was a little lucky, fortunately he didn't refuse his request at that time, otherwise it would be a big loss if he lost such a subordinate.

The main vein of earth fire is like a strengthened version of the magma river, but the scorching heat here has reached its peak, and I am afraid that Chu He will take out a piece of dark iron, and this temperature can easily melt it into iron juice without much effort.

If you guessed correctly, this main vein of earth fire is at least a high-grade level, and it may even be almost a peerless line, far from being comparable to the earth fire vein of Qingling Mountain in the past.

It's a pity, if it weren't for the secret realm of the dark water, with such an earth fire vein, if he could make full use of this majestic firepower, it would be enough to raise his alchemy level by a few percent, maybe even the elixir-level elixir could be tried.

When the alchemist saw the extraordinary Earth Fire Vein, he was naturally very happy, but the fact was not what he wanted, but it made Chu He feel a little more regretful in his heart.

I don't know how deep it is under the fire veins of the Dao Dao, but it is obvious that there are many white earth fires in it, and even if Chu He has the Blue Ice Spirit Armor, he will have to bear a lot of risks if he goes down.

Fortunately, with Xuanwen's help, he would have to return to the passage at the entrance and collect the imperfect heavy water Mithril inside.

"Hmm!" Suddenly, the trace of induction from Tianji Star was strengthened a lot, which surprised Chu He.

Even if it was on the line before, it was still looming, and although the general direction could be detected by following the induction, at this time, its source was also revealed.

Even if it was only for a moment, it was enough to distract the Chu River: it was in the depths of the lower reaches of the Earth Fire Vein!

The rolling earth fire flows, and there are still one or two vacant areas here, which can make the Chu River breathe a sigh of relief, but when it comes downstream, the Yongdao is a lot smaller, and there is no space where the earth fire magma does not exist.

In other words, if you want to enter it, you can only pass through the earth fire magma, and there are a lot more white earth fires in it, which is enough to make Chu He have a lot of scruples in his heart.

"Whoa. ”

At this moment, a sound came, and Xuanwen had already flown out from under the magma river, holding it in both hands, and above it was a mass of heavy water Mithril surrounded by the power of the air.

Strange things such as heavy water Mithril, although xìng are as good as water, but the quality is extremely heavy, and only a few kinds of strange iron and dark steel can weigh as much.

Don't look at Xuanwen holding this lump is not big, if it is measured, I am afraid that it will weigh thousands of catties.

Heavy water Mithril is silvery-white with a slightly jet-black sè, and to a certain extent, it is the same as the mercury seen in previous lives. Chu He didn't dare to slack off, and immediately put it away through the storage ring.

Wen saw that Chu He put away the heavy water Mithril, jumped down again, and searched the bottom again.

Chu He didn't stop him, but frowned and turned his head to look away.

Downstream, it turned out that there was a change at this time!
