As soon as the words fell, Liu Jingyu and the others were shocked.

Before they could come to their senses, a figure had already arrived in front of them. Holding the seven-foot Emperor Yan Sword, the four flames on the sword body were burning, and the fire was great. I can't feel a trace of temperature, but it gives people an unapproachable destructive power.

"Huh?"

Liu Jingyu and Chen Fuyun's faces were stiff.

The flames on this sword were so strange that there was a sense of déjà vu. Immediately, one word flashed in both of their minds, Linghuo!

That's right.

The sense of destruction and inaccessibility that the four-colored flame exudes is the feeling that can only be emanated by spiritual fire. There are also people in the Protector Mansion who have spiritual fire, and they have also been exposed to it, and it feels similar to the flame on this sword.

Merely.

They are also people who have seen the world, and they also know that the colors of spiritual fire are strange. Basically, there are very few spiritual fires that are exactly the same color, so wouldn't there be four spiritual fires on this young man's sword?

It can't be.

The rarity of the spiritual fire is self-evident, and it is one of the treasures that many strong people want to pursue in their lives. This young man has the strength of a shackle realm powerhouse at a young age, and with the addition of four spiritual fires, it is obviously a bit impossible. Yang Yanghua, Xia, hundreds of schools of thought contend, I really haven't heard of anyone with such a background.

And with it.

Liu Jingyu's attention shifted from the Emperor Yan Sword to Sunan, and asked vigilantly:

"What do you want to do?"

Before, they did have a little disrespect for this young man verbally, and he was afraid that this young man would wash his shame in blood, so his spirit was very tense.

"I won't stop you if you want to go, but don't forget the previous agreement. If I want to invite him one day, you must come to my aid, or else ......"

But Sunan didn't pay attention to Liu Jingyu, but said to himself, which made Liu Jingyu quite unhappy, but he couldn't say anything, after all, the person in front of him had just killed a fourth-level demon beast.

“......”

Chen Fuyun and Qin Lian didn't speak, they just glanced at each other, and they naturally knew what Sunan was referring to. However, they were very curious, what else did a powerhouse in the Shackles Realm need them to do?

"I, Chen Fuyun, am also a trustworthy person, Shaoxia saved our lives before, and we should repay this affection. ”

Chen Fuyun was silent for a while, and finally responded.

They had always thought that Sakura's halfway way up was her own sake, but now it seems that it was completely Sunan's fault. At that time, I didn't even say thank you, and I couldn't help but feel that my old face was flushed.

Qin Lian was also silent.

At this moment, she had mixed feelings in her heart, she never thought that the young man in front of her was a powerhouse in the shackle realm. If her attitude eased a little bit before, and she was friends with him, would she still need to go out in person in the family's resource war? Directly ask Sunan to appear instead of her, wouldn't the Qin family win steadily?

"Hey......"

A sigh of remorse.

......

......

"Let's go. ”

Sunan didn't pay attention to them, turned around and walked like a deep pool in front of him. As he passed by the crocodile's side, a beam of cyan flames burst out from his palm, instantly turning the crocodile into ashes.

Mo Zhengfeng and the others had just recovered from the shock, and Mo Zhengfeng looked even more stunned and unbelievable. He has fought in southern Jiangsu, so he naturally knows the heritage of southern Jiangsu. But now he can actually slash a fourth-level demon beast with one sword, this is a bit too exaggerated, right?

It's like a person whose strength is as great as yours, and suddenly one day he can match the strength of your whole body with the power of one finger, which is completely qualitatively transformed.

It's only been a few days?

Mo Zhengfeng looked at Sunan's eyes and looked at the gods, and secretly felt a chill in his heart. Fortunately, I didn't go too far before, otherwise ...... He didn't dare to think about it, just gasped.

"What's that?"

At this moment, he suddenly noticed that there was a crystal flickering faintly on the corpse of the blue crocodile that had turned to ashes.

"Demon Crystal!"

He was shaken.

After the demon beast is psychic, it will condense the demon crystal in the body, but not all demon beasts will have it, and the number of demon beasts with demon crystals is only one percent, I didn't expect this blue-veined crocodile to have it, no wonder even Liu Jingyu is not an opponent.

"Demon crystals?"

Sunan's attention was originally on the bottom of the pool, and after hearing Mo Zhengfeng's voice, he shifted his gaze to the blue-striped crocodile that had been burned to ashes. At this glance, I found that in the ashes, a fiery red crystal was shining, emitting a faint red glow.

He naturally knew the usefulness of the demon crystal.

It can be used to quench weapons with rare metal materials, and it is also an item needed for the formation, and at the same time, it can also directly absorb the spiritual energy in the crystal for cultivation, which is a rare treasure.

But now there is only one.

"As far as I know, you have been in the middle stage of the half-saint bottleneck for a long time and have not been able to break through, so you can take this demon crystal. ”

Sunan's eyes were flat, as if what he was seeing in front of him was not a demon crystal, just a mundane stone.

"Master Su, do you really want to give me this demon crystal?"

Mo Zhengfeng's eyes were glaring, and he couldn't believe it in his eyes.

If it was a first- or second-level demon crystal, he wouldn't have such a reaction, this is a fourth-level demon beast. Whether it is in the official market or in the black market, it is a priceless existence, and many people have fried the third-level demon crystals to sky-high prices in order to temper a weapon in their hands. If this fourth-level demon crystal is brought to the market, it will definitely cause a lot of shock.

Because even in the Medicine God Valley, there are only a few demon crystals of the fourth-level demon beasts, and they are still placed in the inner hall and suppressed by the masters, and no one can see them. Now Sunan actually said that he would send him, it was too generous, he couldn't believe it.

"Really. ”

Sunan did not hesitate and nodded slightly.

The fourth-level demon crystal was not of much use to him, refining the weapon, his Emperor Yan Sword had already exceeded the range of the fourth-level demon crystal quenching, and it needed at least five or six levels. The Yunshan Great Array is the same, there is no level six at all.

"Let's go. ”

Immediately, Sunan was not delayed, and jumped down the deep pool, and Mo Zhengfeng, Lin Qingqing and others also followed one after another. Although Tan Zhongzhi's water had been cleaned by Mo Zhengfeng, this gap had seeped out a lot again.

Sunan's mind moved slightly.

The power of Emperor Yan, which shimmered red, overflowed from his palm, and then quickly approached like a lake, opening a passage in the lake water about one meter deep. As darkness flashed in front of them, everyone disappeared into a two-meter-wide cave at the bottom of the pool.

The cave winds in an S shape, about 20 meters. There is water, and there is also a parade on the edge of the passage formed by the power of the water creatures of the Outer Emperor's Fire. The cave was very narrow at first, but it suddenly became open ten meters behind, and the people of southern Jiangsu passed side by side.

The real fire in his hand flickered, and with the help of the light, it was obvious that there were artificial chisel marks in the passage.

"Somebody has been here. ”

Mo Zhengfeng whispered behind Sunan.

"The spirit veins have been formed for a long time, and it is normal that we are not the first batch. The aura in the spiritual veins belongs to natural precipitation, and the aura in this cave is one or two times stronger than the outside world, and it will not let us down inside, so don't worry. ”

Sunan is not worried.

The spiritual vein is not an ancient tomb, even if there are many people, at most, the spiritual energy in the vein will be a little scarce, and it will not be depleted to that extent. After all, the spirit veins can repair themselves, and looking at the chisel marks on the rock wall, it is obvious that they are some age.

After about three minutes of walking, a faint blue light shone down from overhead.

"It's here. ”

Sunan jumped up and came out of the rock path, and immediately a thick mist aura swept through his body, making every pore of him unintentionally stretch out, and the richness was even several times stronger than that of the Yunshan Great Array. But the scene in front of him was beyond his opinion, and his spiritual consciousness couldn't help but disperse.

"Here?"

After Mo Zhengfeng and the others came in, they were all stunned, because after coming in, there was a hole in it, which was completely different from what they imagined.

They originally thought that it was a natural cave inside, and the five fingers were missing in the dark, but the scene inside was a bit too exaggerated.

The huge cave is the size of a basketball court or two, and the two rows of one-man thick stone pillars in the middle are carved with various animal figures, and some unintelligible characters. There was a blue light flashing all around, emitted by an oil lamp fueled by something unknown.

Apparently, this place was once inhabited by people for a long time.

"Everyone be careful......

Mo Zhengfeng quickly began to be alert, but before he finished speaking, Sunan's voice came:

"Don't worry, there's no one here. ”

His spiritual sense had already scanned the vast space, but he didn't notice the existence of any living creatures, and then said, "You are free to move around and find a place to cultivate, I'm exploring." ”

Then Sunan ignored Mo Zhengfeng and them, and walked straight up by himself. Although the cave was hand-hewn and the size of a football field, it was not rectangular but irregularly shaped, and the end was even L-shaped.

"Are you sure there's a secret passage ahead?"

Just when Sunan was at the L-shaped corner, he suddenly muttered to himself.

"Of course. ”

Immediately, a voice came from his head. It was none other than the black figure in the Open Heaven Creation Tower, who was sitting on a seat in the hall of the Creation Tower and talking to Sunan at the moment.

"I believe you for now. ”

Sunan didn't hesitate, the figure had no intention of harming him, so he believed him as a friend for the time being. Following the figure's instructions, he walked to the end of the L-shaped hall, fumbling for the entrance mechanism of the secret passage, and asked:

"I don't know what your name is these days, can you tell me?"

Although this figure usually has a bad attitude towards him, it is not bad. When he was about to enter the first floor of the Open Heaven Creation Tower, he was at least kind enough to remind him that there was a threat, although the danger was not encountered, the good intentions were still real. But Sunan didn't expect him to say it, after all, this figure's attitude towards him these days is not very good to be honest.

"True Martial Heavenly Monarch, Feather Transformation Green, Blue Emperor!"

As soon as Sunan's words fell, the voice of the figure came out. The words were cold, but they were speaking of a great name.

"Qingdi, you look very powerful?"

Sunan raised his eyebrows slightly.

Just by name, he couldn't guess Yu Huaqing's true identity, so why did he appear in the Open Heaven Creation Tower in the state of a remnant soul. However, when he asked, Yu Huaqing didn't pay attention to him for half a minute, and only said coldly after half a second:

"Don't move, the secret passage switch is three squares under your left hand, press it. ”
