Xuantian Dragon Zun

Hiss hiss. . .

Halfway up the mountain, bursts of hissing sounds could be heard from time to time. Under the burning of the nine-color true fire, one after another blood needle tree turned into a ball of blood-red strange substance, which was taken into the Dantian world by Du Long. That blazing sun star warmed up.

For some reason, he always felt that this kind of blood-colored liquid would be of great use, and it was best not to let it solidify when exposed to cold. Just keep it in this liquid state, which would be the best storage environment.

call!

After continuously collecting the blood-red substance from dozens of blood needle trees, Du Long exhaled a long breath. It was really tiring to maintain the nine-color true fire burning and refining the blood-red substance for a long time. .

"Not good!" After taking a long breath, Du Long found with some depression that the sky around him gradually became pitch black, and then he softly exclaimed: "It seems that we have to find a safe cave to hide as soon as possible. !”

With a flash of thought in his mind, he immediately dodged and flew forward. Even if there were blood needles that continued to shoot at him, they could only shoot them down and did not continue to use real fire to burn and refine those missiles. Dryad of Blood Needles.

Just like this, he continued to shoot with blood needles, and after wandering around the mountain for an hour, he still couldn't find any trace of the cave.

In desperation, Du Long could only give up the idea of ​​continuing to search for a safe cave on this mountain peak. After a slight hesitation, he gritted his teeth and flew towards the sky.

He almost flew upwards directly. The height of the ceiling of this huge underground world was only a few hundred miles. Compared with Du Long's current speed, it only took him three to five steps to get up.

Peng!

Both feet stepped heavily on the roof of the cave, making a violent roar. Du Long stood on the stone wall of the cave roof with his head down and began to look at the cave wall in front of him.

According to what he observed along the way deep into the underground world, there was no cave at the top of the entire underground world, so he simply gave up the plan of looking for the cave entrance on the top of the cave.

snort!

With a soft hum, the top-grade artifact sword in Du Long's hand flew up and down, turning into dazzling swords and electric snakes, and then slashed hard towards the cave wall in front of him.

That's right!

In order to find a safe cave to stay in, he decided to dig a cave with his own hands on the stone wall of the cave roof, and then use this artificial cave to temporarily hide.

Clang clang clang. . .

Originally, he thought that with his own strength, it would be abnormally easy to dig a cave on the roof of the cave. However, when the sword in his hand, which was no weaker than a top-grade super-artifact level, fell on the stone wall one after another, the result was that But he was dumbfounded.

Lights of electric fire burst out one after another, and the sky was full of sword light slashing on the stone wall, but it was unable to cut open the stone wall. It felt like an ordinary person using a kitchen knife to chop through a copper wall and an iron wall.

Waves of tooth-aching clashing sounds of gold and iron continued to resound in this underground world. After dozens of slashes, Du Long stopped with some depression.

"Damn! What the hell kind of rock is this?! Ever since I entered this underground world, I've begun to doubt my own strength!" Du Long said rudely, somewhat depressed.

Just as he said, with his combat power that has reached the strongest level of the Emperor, he can easily pick up stars and destroy the sun in any immortal world, and it is easy to wipe out a star field with a wave of his hand. .

However, with such terrifying strength that reaches the sky and the earth, he can't even cut through a mere cave wall at this moment, and he couldn't even cut through a big tree before. All these things really made him doubt his own strength.

‘Du Long! It's not that the cave walls are made of hard minerals, but that there is a layer of magic circle energy guarding them. . . ’ A clear and sweet voice began to resound in his mind, and it was the Ring Spirit Ling’er who couldn’t help but remind him.

Du Long's initially depressed expression was slightly shaken. The ring spirit Ling'er's voice was like the sound of nature, making him seem to see some hope.

"Is there a magic circle guarding the stone wall on the top of the cave?! Ling'er! Could it be said that the entire underground world is covered by an extremely powerful magic circle?!" The ring spirit Ling'er rarely spoke, and Du Long naturally wouldn't Let go of the opportunity to question her.

"It should be!" Ring Spirit Ling'er also replied with some uncertainty: "My understanding of this underground world is also very limited. You have to explore everything carefully by yourself. Remember to be careful, Qian Don’t rush for success!”

"I understand!" Du Long naturally didn't dare not listen to Ring Spirit Ling'er's rare and serious warning.

After a casual response, he once again focused his attention on the stone wall at the top of the cave in front of him. A knife flashed past and he slashed at the cave wall with all his strength again.

clang!

With a deafening sound of gold and iron clashing, Du Long used his Thunder Eyes with all his strength, and the thunder and fire light shot out from his eyes like real substance, staring at the stone wall at the top of the cave in front of him.

As the light of electric fire flickered, subtle mysterious formations could be vaguely seen on the cave wall!

Sure enough, as the Ring Spirit Ling'er said, the reason why the cave roof of this huge underground world will not collapse is because it is supported by the magic circle.

If she hadn't reminded him, Du Long would not have been able to capture from the fleeting changes in formation patterns behind the electric light that the cave wall was actually protected by some mysterious magic circle.

"I don't believe it! Since the roof of the cave is protected by the energy of the magic circle, can't the ground also be protected?!" Du Long muttered with some disbelief.

Then he immediately dodged and flew downwards, returning to the mountain peak in the blink of an eye. Then he found a cliff and started slashing it with his knife. Since he couldn't find a safe cave on the ground, he might as well just do it himself. Open one up.

Clang clang clang. . .

As the harsh sounds of gold and iron clashing resounded under the cliffs, Du Long was somewhat depressed to discover that there were actually bloody formations appearing on the surfaces of these cliffs.

In other words, the entire underground world is actually under the protection of a super magic circle. Just from the fact that he can only arouse a small part of the energy of the magic circle to show up when he attacks with all his strength, you can see how terrifying this big formation is in front of you. !

"Damn it!" Du Long yelled angrily and depressedly: "Is this really the case that there is no way to go to heaven and no way to go to the earth?! If there is some kind of irresistible danger, wouldn't he have no place to hide? ah?!"

As he said, the situation at this moment really felt like there was no way to go from heaven to earth. With the strong sense of crisis constantly emerging in his heart, Du Long would inevitably feel restless and irritable.

"Should we continue to use Nuwa's space-time footwork with all our strength to see if we can successfully escape from this weird area?!" Du Long murmured to himself: "No! That would be too risky, and we must find other ways!"

As soon as this idea came into his mind, he was immediately rejected by Du Long. He really didn't want to try again due to the frightening feeling he had experienced while using Nuwa's time and space footwork before.

After reaching the level of Emperor of Heaven, he has a certain ability to predict unknown dangers. Since he knows that method is not feasible, he naturally does not want to waste time thinking about it for too long.

Seeing the sky gradually getting darker, the uneasy feeling in his heart became more and more intense. Du Long felt a bit like an ant on a hot pot, with one solution after another flashing through his mind. In the end, they were all rejected by themselves.

"Damn it!"

Frustrated and angry, he couldn't help but kick a stone, and kicked the stone away on the spot. He watched it fly out of the detection range of his spiritual consciousness, and finally disappeared into the vast mist.

Du Long's heart moved slightly, and a bright light flashed in his mind. He stopped talking nonsense immediately, and directly sunk his mind into the world of Dantian, and then pulled out a fist-sized portion of liquid from dozens of blood-colored liquids.

As soon as his mind moved, an ordinary space formation stone immediately appeared next to the liquid, and then he controlled the liquid to wrap the ordinary formation stone.

After finishing all this, Du Long directly moved the liquid wrapped in the ordinary space formation stone out of the blazing Sun Star. As the temperature dropped, the blood-red energy began to solidify rapidly and turned into a blood-colored crystal stone.

Whoosh!

This solidified blood-colored crystal suddenly appeared in front of Du Long. Looking at the blood-colored crystal, Du Long showed a look of relief on his face.

As the ordinary space formation stone was wrapped in the blood-colored crystal, the entire blood-colored crystal successfully shielded the energy fluctuations emitted by the space formation stone inside, and this was also the effect Du Long wanted to achieve.

I saw that he directly placed the blood-colored crystal in a stone crevice, then glanced around at the world that had become many times darker, and then entered the formation space inside the blood-colored crystal.

Then his figure disappeared without a trace again in that ordinary space, leaving only a formation stone flashing with gray light. It was the time and space island formation stone that he brought into the underground world.

In the ninth space-time island, Du Long, who was in the form of three heads and a thousand arms, was sitting cross-legged on the ground. Next to him was a virtual scene. It was pitch black inside and almost nothing could be seen.

However, this virtual scene is actually the underground world outside the blood-colored crystal.

Du Long divided a small portion of his more than a thousand minds to continue observing the underground world outside the blood-colored crystal, while the other minds began to reinvest in cultivation.

After traveling in the underground world for so long, the mist between heaven and earth has just undergone abnormal changes. Who knows how long this cycle of changes will last, so Du Long must seize the opportunity and learn more about the Five Elements of Heaven while he is free now. secret.

Time is passing slowly. The flow rate of time inside the Ninth Spacetime Island is a million times that of the outside. A moment in the outside world is several years inside.

Du Long was not in a hurry, but was quietly observing the situation in the virtual screen, always paying attention to various changes in the underground world.

'really. . . The underground world is completely dark! ’ As the world outside the blood crystal stone was completely immersed in absolute darkness, Du Long couldn’t help but mutter silently in his heart: ‘I just don’t know. . . What kind of terrible crisis is hidden in this frightening underground world? ! ’

As time went by, the virtual screen was immersed in a state of darkness and silence, and no abnormal changes could be seen at all. This also made Du Long gradually begin to wonder whether the previous uneasy feeling was an illusion.

Buzz, buzz, buzz. . .

Suddenly, in the pitch-black virtual screen, a strange buzzing sound began to be heard from the silent state. This sound was very strange and seemed to be somewhat similar to the buzzing sound made by flies when flying.

As the sound rang out, Du Long's heart tightened for no reason. He vaguely felt that some unknown danger had appeared. He hurriedly braced himself and tried to figure out the source of the sound.

As time went by, the sound became louder and louder, as if a swarm of flies were flying past the ears. This buzzing sound gave people a strange feeling of sore teeth.

Buzz!

Suddenly, a blood-colored ripple flashed across the virtual screen. Du Long instantly captured the shape of the blood-colored ripple. It was a sharp cone-shaped air blade passing through the air.

Soon, another bloody ripple passed through the air and passed through the virtual screen again.

Gradually, the number of these bloody ripples began to increase dramatically, flying past the virtual screen like raindrops. They did not attack any mountains or vegetation, they just cut through the sky like this, filling this pitch-black area. The world brings extremely dazzling bloody fireworks.

"What the hell is this?! Are they the terrifying things that make even the most powerful commander-level beings in the outer realm afraid to step into this underground world?!"

In the ninth space-time island, Du Long looked speechlessly at the blood-colored pointed cone-shaped ripples that kept crossing the virtual screen in front of him, and he had no idea what these things were.

"This should be some kind of sonic attack formed by the formation of the underground world!" Ring Spirit Ling'er's voice sounded at the right time: "Presumably this formation of the underground world should be formed by a powerful vampire. Deployed by strong men, don’t underestimate these sonic shocks. Once hit, it will definitely be miserable!”

"Ling'er! Do you recognize this sonic attack method?!" Du Long raised his eyebrows slightly.

"I have seen similar attack methods before. This is a magic circle attack unique to the vampires outside the territory. The vampires have extremely amazing research on sound waves and have achieved a lot of results!" Ring Spirit Ling'er replied in a deep voice.

Although she can't easily lead Du Long's rescue mission, it doesn't mean that she can't answer some questions she knows. This is what Pangu Ancestor reminded before, don't deliberately avoid Du Long, it's your own job. You still have to do a good job, otherwise you should try to avoid misleading Du Long if it is not your responsibility.
