"So, that evil soul is below?"

Looking at the pool water, Xiangru's face was solemn. He could not have imagined that such a crisis was hidden in the calm pool water.

"It should be."

Zhou Shu nodded, as if thinking, "I'm still wondering why I can't even sense any trace of the evil soul along the way. It turns out that it's all here."

After those monks entered the eighth level of heaven, they came here and were stained with pool water or the surrounding energy. Unconsciously affected by the evil soul, they gradually changed into corpse refining. If Zhou Shu had not been careful, Xiangru would have been like this.

But no wonder, there is an evil soul hidden in this pool of water, but it cannot be seen at all on the outside, and it cannot be detected by Zhou Shu's spiritual sense.

Xiangru said suspiciously, "Why doesn't the evil soul come out?"

Zhou Shu nodded, "This is what I am thinking about, and I don't understand."

Why do evil souls hide in the pool water? Since they have become evil souls, they are unrivaled in this secret realm, so it is better to come out? It is easier to devour cultivators, and there is no need to use traps. They may even use the power of cultivators to escape from the secret realm and go to the Xuanhuang Realm to harm sentient beings. Why hide in the pool and slowly affect the cultivators and devour the soul? It is not very suitable for the identity of the evil soul.

Looking at Chi Shui, he slowly said, "If you want to find the answer, you can only go down and take a look."

Xiangru was stunned, "You really want to go down, but below..."

Zhou Shu said calmly, "We must go down."

Since he has been known as the Human Emperor, he should work hard for humans. How can he be immortal when facing evil souls? He has already killed an evil soul, and it is not inexperienced, even though the evil souls here are much more powerful.

"Yes, I'm here, how can I not find out what's going on? OK."

Xiangru turned to the Dragon Pool, and a faint smile appeared on the corner of his mouth, giving a kind of spirit of sacrificing his life to accompany a gentleman.

Zhou Shu smiled unconsciously and nodded, "Don't worry, wait for them to come."

This waited for more than twenty days.

"Brother Zhou, don't you really need to look for it?"

Xiangru had a little doubt, "It's been too long, they won't be trapped, right?"

Zhou Shu smiled slightly and looked calm, "It's okay, I just use this time to think about things."

Xiangru nodded and didn't ask much.

He said calmly, but he has been paying attention to Qingque and Caiying. Every once in a while, he will use the eighth sense to detect it.

The two women were indeed trapped, very tired, and even injured several times, but they were not in danger of life. However, he believed that they could escape by relying on their own strength rather than relying on him, so that they would gain greater and more valuable gains.

A few more days passed.

In the distance, a man and a sword were slowly walking over.

He looked haggard, but his steps were firm, and his face was filled with irresistible excitement and joy.

Zhou Shu looked at them from afar with a satisfied smile.

"You're here."

"Here you come."

Qingque nodded slightly, then sat down on the ground, as if he had lost all his strength, but the smile at the corner of his mouth did not diminish at all.

Zhou Shu smiled slightly, "What good thing has happened?"

"A great thing!"

A green light flashed, Caiying jumped out of the sword and shouted, "I..."

I felt relieved without saying a word, and the green light on my body appeared and disappeared, like a candlelight that would go out at any time, and the oil was gone and the lamp was dry.

Zhou Shu had already arranged it, and two white mists flew out of his sleeves, completely wrapping them up.

The rich and unconverted vitality allows them to recover quickly.

"Qing, show him what we have gained!"

As soon as he recovered a little, Caiying screamed impatiently. Qingque nodded with a smile, took out a few things from the bag and placed them in front of Zhou Shu.

Zhou Shu's eyes fell on an item and was immediately attracted.

It was a square piece of metal. At first glance, it was a very ordinary mineral material, but the color was a bit special, and it was mixed with blue and black.

But if you look closely, you will find that the blue and black are changing, and their positions are constantly changing, just like the undercurrent undercurrents. The blue is the moving currents, and the black is the undercurrent vortex.

Zhou Shu was shocked, "This is..."

"The Iron of the Dark Sea!"

Before he could say it, Caiying had already shouted out loud, with a lot of pride, "It was Qing who told me, you don't know, right?"

Zhou Shu nodded, "Actually I know."

"You know, do you know if you go find it earlier?"

Caiying's face suddenly changed and she said angrily, "Don't you know what it is useful to me? Humph, you don't care about me at all!"

Zhou Shu was not angry and continued, "This is the Dark Sea God Iron, an important material for the Blue Sword to be able to upgrade to the eighth level. But it's not that I don't look for it, but that I can't find it now. Just like the Dark Sea Iron that refines the Blue Sword, the Dark Sea God Iron is not a mineral in the Xuanhuang Realm. It is a hundred times more precious than the Dark Sea Iron. I think there is definitely not in the Xuanhuang Realm... You can find that it is really a great luck, and it is also God's will."

Qingque said in a warm voice, "It was found by Caiying. She has always felt its breath before we can find it."

"It's us!"

Caiying quickly corrected, "Without you, I am still in that palace now."

"The Qingyan Sword was originally made of the Iron of the Sea, so it can sense the location of the Iron of the Sea. In fact, it has no breath itself. At least we immortal cultivators cannot sense it." Zhou Shu looked at the Iron of the Sea with a little bit of gratitude, "It would be great to have it now. I thought that only after ascending to the Immortality could the Iron of the Sea can I upgrade the Iron of the Sea, but I didn't expect that I could do it now. Caiying, you have to go further."

"Call me the Lord of the Palace."

Caiying turned her head, still looking like she didn't want to pay attention to Zhou Shu.

This dark sea god iron is the biggest gain they have gained from that palace. For this reason, they have done everything they can do, and it is not necessary to say how hard they have worked.

It is alien iron outside the sky, and there is no level difference, but it can penetrate the spiritual energy and vitality, which is very consistent with the immortal cultivators in the Xuanhuang Realm. It has to be said that it is a real treasure, and it is even called a god. It is known as a god gift.

Its value is no less than that of the Kaitian Stone.

The magic weapons refined with the Iron of the Nether Sea are at least level six or seven, and the best possible one is very high, while the Iron of the Nether Sea even has a slight chance of impacting the Ninth Level.

The ninth-level magic weapon is the ultimate magic weapon. It is the best magic weapon that immortals can refine. It is one point higher than the heavenly magic weapon. It is called an immortal product. If you enter the fairy world, you can be ranked alongside the immortal weapon.

Qingque was trying to smooth the field, "The flying swords that have been promoted need a lot of materials. What are they? Let me see if I have one?"

"Need not."

Zhou Shu shook his head, "I have prepared everything else long ago. Now I have a different firearm furnace on my body. After solving the problem here, I can directly refine and upgrade the level. Moreover... the heavenly tribulation brought in the secret realm is easier to deal with. It's a real opportunity."

"It's an opportunity, and it's the result of your hard work."

Qingque nodded with a smile and looked at Caiying, "Look, he still cares about you. Apart from this, the others have been prepared long ago."

"snort……"

There was still a grievance voice, but Caiying turned around and was already smiling and full of joy.
