Chih!

A blood-colored pointed cone-shaped sound wave air blade broke through the air and instantly shot on the trunk of a big blood needle tree. Under Du Long's horrified gaze, the blood-colored pointed cone-shaped sound wave air blade penetrated the trunk directly, and then shot away without decreasing force.

Hiss!

Looking at the hole in the tree trunk, he couldn't help but take a deep breath. The blood needle trunk was something he could not cut with the top-grade super artifact sword. When facing the blood-colored pointed conical sound wave air blade, it would be pierced instantly?!

Hoosh!

Another blood-colored conical sound wave blade broke through the air and then landed on a huge rock in the virtual picture. This huge rock that could not be cut by the knife was bombarded and shattered on the spot.

Du Long finally understood what the danger was in this underground world. It turns out that after this world enters the dark night state, this extremely fatal sharp cone sound wave air blade will appear.

As his mind turned around, he immediately made a decision and summoned several monsters that had just reached the strength of the God-level, and then ordered them to move within a radius of twenty meters.

Under the pressure of his Heavenly Emperor, how could these two monsters who only reached the strength of the God-level were afraid to have any objection? They could only stay within twenty meters next to the blood-colored crystal according to his instructions.

In the virtual screen, these two demon beasts with the strength of the God-level monsters seemed not clear about how terrible the sound wave air blades emitted from the sky were. They were still curiously looking at the blood-colored sound wave air blades that flashed from time to time.

Hoosh!

Suddenly, a blood-colored pointed cone air blade flashed and instantly passed through one of the monsters. The blood-colored sound wave air blade with a sharp front and a large back twisted the monster that had only reached the strength of the God-level, and it burst into pieces of flesh and blood all over the sky.

The poor monster didn't even have time to scream, and died inexplicably. This scene saw the other monster's hair standing upside down, and it was obvious that it was very scared by this scene.

‘Do your all-out effort to avoid the bombardment of these blood-colored sound wave air blades. As long as you can survive, I will give you a free body!’ Du Long’s divine sense of transmission fell into the mind of this monster at the right time.

His goal is very clear, that is, to test whether the monster in front of him can dodge the blood-colored sound waves and survive in this mysterious and terrifying dark night environment of the underground world.

"Yes! Sir!"

The monster felt the terrifying imperial pressure, so he naturally did not dare to disobey any of Du Long's instructions. For it, as long as the imperial powerhouse had a random thought, he could destroy his soul.

Therefore, it is clear that only by obeying the instructions of this mysterious emperor-level powerhouse can he have a chance to survive. As long as he can survive the bombardment of these blood-colored sound wave air blades, he will be able to regain his freedom.

Looking at the blood-colored sound wave air blades that flashed from time to time in the air, the flight speed of these sound wave air blades was not too fast, but because of the layer of fog, when they were discovered, they often had already arrived not far away.

In this way, the difficulty of dodging increased a lot. The monster could only carefully observe the changes in the light in the air. Once it was discovered that a certain light flashed, it was ready to dodge.

Swallowing...

Blood-colored sound waves and air blades broke through the air, and gradually several shots shot from the monster standing, but they were successfully dodged by it.

The monster then breathed a sigh of relief. It was obvious that although the blood-colored sound wave air blades in front of him had amazing attack power, they were not unavoidable.

However, before it was happy for too long, the number of blood-colored sound wave air blades attacking it gradually became denser, as if the formation of these blood-colored sound wave air blades had discovered the existence of this monster and began to focus on taking care of it.

As more and more blood-colored sound wave air blades shot towards the monsters one after another, it finally could no longer remain calm and began to rush back and forth frantically, trying its best to dodge those blood-colored sound wave air blades.

Chih!

The strength of this monster was always too weak. Not long after dodging, it was cut by a blood-colored sound wave air blade, leaving a deep bone-visible scar on its body on the spot.

Oh yell!

The severe pain made the monster unable to help but let out a long roar to the sky, but its long roar could not slow down the bombardment of the blood-colored air blades all over the sky. A blood-colored air blade flashed instantly and shot directly through its body.

With a muffled sound of Peng Ran, the monster with the power of the Heavenly God level was bombarded into pieces of flesh and blood on the spot, scattered in this blood-colored underground world.

Du Long continued to observe the surrounding environment expressionlessly. The two monsters just now were two evil beasts in the Cave Heaven world. Their life and death would not cause any burden on his Taoist heart.

The blood-colored sound wave air blades in the virtual picture gradually became thinner from the beginning when they were dense. It can be seen that when living things appear, the attacks of those blood-colored sound wave air blades will become denser.

Seeing that the blood-colored sound wave air blade attack became thinner again, Du Long summoned two monsters again. This time, they were monsters that reached the strength of the Hunyuan level, and they were the leopard monsters and cat monsters who were more good at body speed.

Du Long's intention is very obvious, that is, to see if these monsters can successfully survive the bombardment of the blood-colored pointed cone air blades in the sky when their body speed is relatively fast.

After explaining the two trembling monsters, Du Long immediately threw them out. The two cat-like monsters smelled a strong smell of blood and saw the fragments of the other two monsters being bombarded with vigilance.

‘Be careful that the blood-colored sound wave air blades in the sky must not be hit by them, otherwise they will have to be bombarded!’

Du Long's voice echoed in both of them. The reason why he reminded these two monsters was that he hoped they could last longer, not that he suddenly had kindness.

Soon, as two living creatures appeared outside, the blood-colored sound wave air blades that had become sparse gradually became denser and began to constantly bombard the two monsters that reached the Hunyuan level.

Not only is these two monsters one level stronger than the previous two god-level monsters, but they are also known for their body speed. The success rate of dodging the bombardment of those blood-colored sound wave air blades has naturally increased a lot.

However, although they survived for a period of time than the two monsters before, they still couldn't escape in the end, and were bombarded by the increasingly dense blood-colored sound wave air blade.

On the Ninth Space Island, Du Long frowned and stared at the virtual scene in front of him, watching the blood-colored pointed conical air blade gradually return to its thin state, and pondered for a while before summoning two figures again.

These are two emperor-level powerhouses who are good at body speed, and they are also his two second-level spiritual servants, and they are also from the Darkness lineage in the West.

"You two go outside, remember to be careful of the bombardment of the blood-colored sound wave nerds. As long as you can survive until the end and not die, I will give you the freedom to the two of you!" Du Long explained to two second-level spiritual servants from the Dark Lineage.

"Yes! Master!"

The two looked at each other, and they all saw a hint of bitterness and helplessness in their eyes. As other people's spiritual servants, their fate is usually at the mercy of others and is often used as cannon fodder.

"Remember not to leave the twenty meters range, go!"

After explaining again, Du Long released the two of them, and then began to continue to observe the performance of these two imperial-level powerful men who were good at body speed under the bombardment of the blood-colored sound wave air blades in the sky.

As expected, they are not afraid of being members of the Dark Lineage who are known for their body speed. These two dark powerful men with the strength of the Emperor level dodge the attack speed of the blood-colored sound wave air blades is many times faster than the previous two Hunyuan-level monsters.

However, no matter how fast they are, they can't escape the fate of being killed by the blood-colored sound wave air blade. Even if one of them uses the Shadow Body Technique and transforms into dozens of clones, they can't escape the tragic situation where the true body is killed.

The blood-colored sound wave attacks seemed to be able to distinguish the true body and ignore the shadow clones. In this way, the role of the shadow clones was immediately weakened to the extreme.

As a Dark Emperor-level powerhouse fell, the situation of another person became precarious. Du Long's voice sounded in his mind at the right time: "Now expand the range of movement, you can move within a mile area to avoid the bombardment of these blood-colored sound wave air blades. As long as you can hold on for another day, I will give you freedom!"

‘Yes! Master!’

The Dark Emperor-level powerful man gritted his teeth, and his eyes that had already felt desperate were once again filled with hopelessness. Du Long's words made him feel that he still had a glimmer of chance of survival.

Whoosh swish swish swish...

Within a mile area, this Dark Emperor-level powerhouse continued to dodge the bombardment of blood-colored energy, while Du Long watched quietly from the side.

The blood-colored sound wave air blades in the sky were like maggots attached to bones, tracking the black figure tightly, which shows that these blood-colored sound wave air blades are not shooting randomly without target.

Time passed by minute by minute. As the last hour was left before the day's deadline, Du Long was shocked.

Boom!

I saw a dark red light appeared out of thin air in the thick blood mist. The light shot on the black shadow with extremely accurate accuracy, instantly exploding.

"Damn! What the hell is that?! Why are there dark electric bombardment among those sound wave blades?! How can this make people trapped in this underground world live?!" After a moment of dazed, Du Long finally woke up and cursed angrily with a little depressed look on the spot.

However, no one answered his doubts at this moment. If this underground world was not dangerous, how could those who were at the strongest commander level of the imperial level outside the domain be discouraged?!

After a long period of gloomy expression, he sighed and finally accepted the reality in front of him. Since this underground world is not only hit by blood-colored sound waves, it is also an extremely deadly dark electric attack, so he can only slightly change the way of testing.

As soon as my mind moved, an ordinary space formation stone immediately appeared on the ground outside. There were several demon beasts of the god level hidden inside that ordinary space.

This time, Du Long did not let the monsters go out to die, but let them hide in an ordinary space formation stone to see if the blood-colored sound wave air blades would attack the space formation stone.

Hoosh!

As a result, not long after, a blood-colored sound wave air blade fell and directly hit the space array stone that emitted a faint fluctuation of energy. The space array stone was shattered in the sound of the puff, and the several heavenly god-level monsters inside also turned into pieces of flesh and blood all over the ground.

"Damn it?! Is this just a coincidence?!" Du Long cursed inwardly and released an ordinary space formation stone again, and there were still a few ordinary monsters hidden inside.

In order to determine whether the situation just now was a coincidence, he used the same method again, but not long after, the space formation stone was bombarded again.

Until this moment, he finally confirmed that it was definitely not a coincidence. It seemed that those blood-colored sound wave air blades would attack all objects with abnormal energy fluctuations, including space formation stones that do not belong to this world, could not escape the disaster.

Gripping his teeth, he summoned a second-level spiritual servant from the Dark Line again, and then sent a set of black armor to him: "Recognize this set of low-grade super artifact-level armor and wear it!"

"Yes! Master!" The dark powerful emperor-level man hurriedly took the order and soon put on the black armor that he recognized him as his master.

"You're out now..." Du Long continued to say the words he had previously explained again, and finally added: "As long as you can live until dawn, I will not only give you freedom, but also give you this set of armor as a reward!"

The black-armored man immediately received the order, and then came to the outside world with Du Long's help, and began to enter a state of full alert, ready to deal with the upcoming dangerous attack.

On the Ninth Space Island, Du Long stared at the black-armored man with a faint look at the virtual screen. The man's body speed was not much faster than the previous two people, but there was a layer of armor made of black matter on the body of the spirit-eating ant beast to guard it.

Du Long's goal of this test is very simple, that is, to know whether this black armor can help the wearer avoid the attack of the blood-colored sound wave air blade!

‘Huh?! It seems that he was not attacked?!’

After a while, Du Long raised his eyebrows and murmured to himself as he saw that the black armored man was not bombarded by the blood-colored sound wave air blades and the blood-colored sound wave air blades around him did not become denser.

After continuing to observe for a quarter of an hour, no abnormal changes were found. Du Long then sent a voice to the second-level spiritual servant from the Dark Lineage and said: "You are starting to move within a radius of 100 meters, be sure to be careful of the bombardment of the blood-colored sound wave air blades!"

‘Abide by the order! Master!’
Chapter completed!
