The Heavenly Knight didn't just summon a thorn worm to come over, with a ripple of space, there were six iron thorn worms in front and back, all of which flashed through the void to the side of the Sky Knight, and as soon as they appeared, they plunged headlong into the rock and soil.

Each of these iron thorn insects has an extreme combat power comparable to the second and ninth orders, although in terms of single combat power, it is much worse than the black-scaled python of the black-robed bishop, but the combination of the six is in the underground environment that they are best at, but it is enough to bring a lot of trouble to the other party.

"Boom Boom Boom ......"

The thornworms soon took effect, and the vibrations and roars of the ground gradually became more and more intense.

"Whew——!!"

As if he finally couldn't stand it anymore, with a terrible roar, a piece of rock and soil not far from the Heavenly Knight suddenly exploded, and the black-scaled python drilled out again.

At this moment, the black-scaled python did not drill out of the rock layer alone, but had three or four iron thorn insects wrapped around its body, and the dozens of mechanical claws of the iron thorn insects were fiercely pulled on the black python's body

However, the Heavenly Knight's Spiritual Brain judged after calculation that it should not take risks for this, so it directly chose to retreat and dodge.

At the same time, he quickly pulled out an alloy shield made of the same active black gold from the storage compartment for defense and blocked it in front of him.

And sure enough, the Celestial Knight's cautious behavior proved to be correct. Because, after the purple-black poisonous aura was spit on the surface of the alloy shield, it immediately aroused an extremely harsh 'snort' sound, corroding the black alloy shield to the point that a large amount of scorched smoke came out, and the surface of the alloy shield even dissolved at a speed visible to the naked eye, turning into pools of black water and falling to the ground, and corroding the ground into pits that were at least the size of a fist.

Even the soil around the pit was slowly stained with a grayish black color that seemed wrong.

After seeing this scene, the Heavenly Knight was even more determined in his decision to avoid the purple-black poisonous aura.

In fact, this can also be called a weakness of active black gold, which is not a weakness.

Reactive black gold is a material that can be automatically repaired when it is damaged, but it cannot be created out of nothing. The so-called repair is actually equivalent to the act of 'rebuilding discarded parts into new ones', rather than 'creating regeneration out of thin air'.

In other words, the automatic repair function of activated black gold requires the support of raw materials to achieve. If the enemy can directly wipe out the material of the active black gold to the point that there is no slag left, so that the material is missing, then naturally there is no way to repair it.

Corrosive, decomposing attacks are exactly the way to do this. Of course, that's not to say that just a corrosive attack will work.

As the crystallization of the highest technology of the Demon Spirit Clan, the peculiar material of Active Black Gold itself has an extremely high limit of damage resistance, it is not only extremely strong and has a very high resistance to energy attacks, but also has a high resistance to corrosive attacks.

Ordinary corrosive substances such as aqua regia sulfate will not even leave a trace on the active black gold when it falls on it.

However, the poisonous gas of the black scale python was not an ordinary thing, it was the specialty attack of a powerful transcendent creature that had reached the rank of the third-level legendary realm, and it was not too strange that it could corrupt and break through the upper limit of the defense of active black gold.

Taking advantage of the gap where the Heavenly Knight retreated because he was afraid of the poisonous gas, the black-robed bishop was finally able to get a chance to breathe, and immediately controlled the black-scaled python to roll around him, and the snake body bent and suddenly ejected.

Boom ——!!

The power that erupted from the sudden exertion of the snake's body forced the ground within a radius of 100 meters centered on the black-scaled giant snake to sink several meters and burst into countless cracks.

And with this terrifying force that shattered the earth, the black-scaled snake suddenly jumped out to the rear, and this jump was more than five hundred meters away. In an instant, it was far away from the range of the Celestial Knight's melee attack.

The area without aura created by the Heavenly Knight before was centered on the Heavenly Knight itself.

And now, after the black-robed bishop stayed away from the Heavenly Knight, in addition to taking advantage of this to distance himself and avoid the attack range of the Heavenly Knight, he was also out of the isolated shroud area without spiritual energy. ，

After re-entering the area full of aura, there was no need for the black-robed bishop to deliberately control it, and the black-scaled python took the initiative to open its mouth, like a giant whale sucking water, frantically devouring the surrounding aura.

That terrifying devouring speed even directly set off a small range of spiritual energy tides like a hurricane vortex around it!

As a large amount of spiritual energy was swallowed into its abdomen, the black-scaled serpent's wounds, which had been injured by the Heavenly Knight, were also recovering quickly at a speed that was visible to the naked eye. Even the coercive aura it exudes has become even more terrifying.

The Heavenly Knight, who was aware of this, immediately chased after him, and the magic array behind him sped up, re-incorporating the black-scaled python into the enveloping range of his 'Spirit Repulsion Fluctuation Force Field'.

"Hiss ——!"

Feeling the aura in the air around him retreat with the approach of the iron bump, even if he urged the devouring power with all his strength, he couldn't absorb the aura again, the black-scaled python was very unhappy, it turned its head to stare at the heavenly knight in front of it, and let out an angry roar.

Then, the black-scaled python's mouth twitched slightly, and then suddenly opened its mouth, and once again spat out the purple-black poisonous gas with terrifying corrosive poison towards the heavenly knight. Before, it relied on this attack to force the Heavenly Knight back, so at this moment, it naturally wanted to repeat the old trick.

However, how could the Heavenly Knight, who was already familiar with the Black Scale Python's attack method, be stumped by the same move for the second time!

"The coordinates are calculated, and the jump begins. 』

The Celestial Knight's Spiritual Brain completed the required calculus data in this short instant, and activated the Celestial Knight's individual space jumping device, causing the entire body to disappear in front of the black-scaled python and the black-robed bishop in an instant after a slight spatial ripple.

"It's ...... Not good!"

Seeing that the enemy suddenly disappeared without warning, the black-robed bishop was slightly stunned, and when he reacted, his face immediately changed drastically, and he realized that something was wrong.

Unfortunately, it was already late.

Through the spatial jump, in the next moment, accompanied by an extremely slight spatial ripple, the Heavenly Knight had already appeared in the void behind the black-scaled python.

As soon as he jumped out, the Sky Knight directly swung out the ship slashing knife in his hand.

Poof——!

The black-robed bishop tried his best to control the black-scaled python to dodge, and controlled the black python to use the back half of its body to actively block the trajectory of the ship slasher.

However, the Sky Knight's Ship Slashing Knife is not just a metal knife, but the most powerful 'High-Frequency Concussion Knife' that can be made with the current technology of the Dream Realm.

Every minute, every second, the edge of the giant blade is actually oscillating at an extremely high frequency amplitude that ordinary people can't detect with the naked eye, and if it comes into contact with other objects, it can theoretically easily crack the molecular structure of any substance, even if it is used to cut steel, it can be as simple as cutting tofu.

To be able to confront this terrifying weapon directly with his physical body in such a situation, even if he uses spiritual power to strengthen the snake body and snake scales, even if every direct collision will be seriously injured, but the black-scaled python can actually be proud.

"Whew——!!"

With a terrible hissing sound, a black snake tail about six or seven meters long fell to the ground with the blood sprayed out.

Faced with the sharpness of the Heavenly Knight's sword slashing sword, the black-scaled python finally failed to completely resist it, and was completely cut off a snake tail.

However, the Heavenly Knight itself is naturally very dissatisfied with this.

The knife it slashed out in this pre-attack was originally aimed at the black-robed bishop who was protected by the black python, but it was still defended by the black python with a snake tail.

Just as the Heavenly Knight wanted to mend the knife again, the black-scaled python suddenly slapped the ground with force, ignoring the pain of the broken tail.

Boom ——!!

With a sound of explosion that made the nearby earth tremble faintly, the black python's severed tail struck the earth and stirred up a large amount of dust, covering its body at once, as if trying to hide itself.

However, through the scanning of the power of data, the Heavenly Knight's Spiritual Brain was not negatively affected by the slightest obstruction of vision, but continued to swing and slash without any disorder.

"Whew——!!"

In the dust, another terrible scream came out.

The Heavenly Knight waved his hand suddenly, and the spiritual power gathered in the palm of his hand turned into a fan, and with a slap, it set off a violent wind and swept away all the mud and dust in the field.

In the exposed clearing, there was no trace of the black-scaled python and the black-robed bishop, but a deep black pit with a thickness of four or five meters was left in place.

Obviously, the black-scaled python actually dug a hole and escaped by burrowing into the ground on the spot, and it is not known whether it was its own judgment or its owner's control.

The performance of the Sky Knight is extremely good, and he is good at air and ground combat, even if he dives under the sea, his combat effectiveness will not be greatly affected.

However, fighting in the underground rock formations happens to be an area where it is not good at. After all, the Celestial Knight's body form is obviously not good at drilling underground.

However, it doesn't matter, because the scientists of the Dream Nation have already considered the operational needs in this area for a long time.

The void around the Heavenly Knight rippled slightly, and then, a black crystalline mechanical puppet with a body length of more than twelve meters and resembling a millipede suddenly appeared beside the Heavenly Knight.

It is said to resemble a millipede, but in fact, the overall structure of this mechanical puppet insect is not the same as that of insects such as centipedes and crickets, because its body has no structural difference between the front and back. The whole thing looked like a steel worm with countless blade-like worm feet growing on the sides of its body.

As soon as it appeared, it plunged into the pit and cave that was carved out by the black-scaled python, and dozens of mechanical feet dug out a large amount of soil in an instant, even the hard rock under the ground was as easy to crush as tofu under the cutting of the mechanical feet and mechanical claws, and in the blink of an eye, the huge mechanical body of more than ten meters long disappeared on the ground.

This is the name given to this mechanical puppet by scientific researchers, which is a special mechanical weapon for the operation of the underground rock formation environment created according to the bionic mechanism of underground insect-like creatures.

Its head is a deformable structure, which can be transformed into a worm-like mouthpiece structure that can bite and tear through prey and hard objects such as rock and metal, or it can combine all the mechanical teeth on the mouthparts into an extremely sharp drill-type structure, which can be used to quickly drill into rock formations, and if necessary, this deformable head mouthpart can also be transformed into a barrel structure comparable to the main gun of a small warship, so as to blast out an energy cannon that is enough to shatter a 100-meter hill!

The circle of blade-like mechanical feet on his side can be used to quickly dig through underground rock formations, or to turn into dozens of blades to brutally cut the body of a prey when wrapping his long body around an enemy;

And this can even adapt to combat in underground areas such as dark rivers in underground rock formations, and its dozens of blade-like mechanical feet can also act as a function similar to fish fins and frog flippers in the underwater environment, so that the ironthorn insect has an extremely fast and sensitive underwater movement ability, and the mechanical body made of active black gold also allows it to be fearless of the squeeze of rock formations deep underground and the terrifying pressure of the deep sea environment.

According to the words of the scientific researchers of the Dream Realm, although this bionic insect-type mechanical puppet is not beautiful, and it is even enough to make many people instinctively feel uncomfortable at a glance, but if you really want to talk about combat ability, it is indeed a very reliable one!
