The palace is very large, at least it covers an area of thousands of square meters, it is very spacious inside, walking through the huge palace hall, Tang San entered the underground part of the lower layer of the palace, passing through the guards one by one, without attracting the slightest attention, like a ghost.

Most of the guards in the palace are undead skeletons, but these skeletons are powerful, each of them is more than two meters tall, and they belong to the powerful cannon fodder among the undead demons.

In addition to the skeleton soldiers, who are hideous-looking ghouls, undead demons made up of various corpses, and some of their bodies are still flowing with stinky thick liquid, which is also unbearable disgusting.

"These lifeforms are really amazing, the corpse is completely an external armor, only the core soul is the real body, I don't know what kind of environment can create this kind of creature. ”

Tang San had a heart to explore everything, and he was always full of interest in the unknown, but thinking of his purpose, he did not delay, but continued to move forward, and in about a quarter of an hour, he finally came to the outside of the dormitory where the undead dragon knight was.

At this time, the undead dragon knight seemed to be in some kind of deep sleep, he sat on a black throne, his whole body was shrouded in steel armor, and he could see a pale face, his eyes were closed, and his consciousness seemed to enter some kind of deep entry.

Guarding the gate were two vampires, each of them an advanced vampire, their scarlet eyes scurrying around, alert for any enemies who might sneak in.

Vampires are terrifying creatures that can hardly die unless they crush their hearts or brains, but of course this is limited to ordinary vampires, once a vampire is leveled. Then even if there is a drop of blood left, they can all be reborn. And it's very fast, amazingly fast. Their eyes have infrared-like abilities, they can easily see hidden creatures, and once they reach the level, they can even detect subtle changes in light and shadow, and the effect of any stealth technique in front of them will be greatly reduced.

Tang San wanted to pass through them silently, but he still had enough confidence in the stealth technique he had deduced, even an advanced vampire would definitely not be able to see through it.

But what really bothered him was that the door behind the vampire was closed, and if it was opened, it would definitely alarm the undead dragon knight, so he had to think of other ways. Let yourself dive into it silently.

Thinking of this, a strange smile appeared on the corner of his mouth, and then he hid in the shadows, and an idea was connected to the dimensional plane, controlling the demon's lair, a powerful Bato Flame Demon was quickly born, and then he released it out of the dimensional plane, and under the control of Tang San's mind, he frantically rushed towards the palace of the undead demon knight.

The advanced Bato Flame Demon is also second to none in terms of combat power among demons, not to mention that it has completely fallen into a rage. The Bato Flame Demon who vented frantically regardless of wear and tear was even more terrifying.

Bang bang bang

Huge black flames burst out from its body, turning into huge meteors and falling towards the palace of the undead dragon knight.

Dozens of flame meteors fell, immediately alarming the bone dragon perched on the top of the palace, and it reacted immediately. With a snort, a huge black breath swept towards the black meteor flames that fell from the sky.

Thundered

A huge explosion rang out, and the palace of the dead was completely covered in countless black sparks. Mars crashed to the ground and immediately set the rocks on fire. This is the highest level of abyssal fire, and it is a rock that can be ignited. This skull dragon was a half-step second-order viscount-level undead demon, while the Bato Flame Demon created by Tang San was just an ordinary baron demon, the gap between the two was huge, and more than a dozen flame meteors were powerless under the breath of the bone dragon.

However, such a movement also immediately alarmed the entire palace of the undead, and the undead dragon knights of the underground palace were also alarmed, and a piece of death power diffused out, quickly spreading to all sides, and the two vampires at the gate turned grim, knelt on one knee, and greeted their masters.

The door opened, the sound of footsteps came slowly, and a powerful aura came to his face, making Tang San who was hidden in the darkness feel a trace of pressure, of course, this refers to his incarnation, only the strength of the second order, and there will not be too much gap with the undead knight, but it is not easy to get the abyss crystal above his head silently, so he needs a chance, and the outside world has created chaos, so it is convenient for him to act.

When the undead knight led the two vampires out of the underground palace and ascended to the upper palace, he saw an amazing scene, a Bato fire demon who was almost burning was wildly wielding his power, and one after another flame meteors blasted out like machine guns without money, completely enveloping the entire undead palace, and the undead bone dragon above the palace spat out a breath, constantly destroying the meteors, and could not spare his hand to solve the Bato fire demon body.

The flames swayed by the Bato Fire Demon are all abyssal fires, once attached to the object, it will continue to burn until it burns everything it is attached to, and the undead bone dragon does not dare to let these flames fall on this palace on a large scale, otherwise it will not be easy to explain if the undead knight asks it.

That's why the two sides have formed a situation of bombardment on both sides, Bato's Yan Demon has a flexible body, constantly throwing abyssal fire around the palace, and the bone dragon can only be frozen, looking very angry, and one after another dragon roars resounded in the sky.

And at this time, the undead knight came, and immediately became the core, attracting the attention of countless demons and undead, only to see that the undead demon showed an angry look in his eyes, pulled out the knight's sword at his waist, and slashed towards the Bato Yan Demon from a distance of hundreds of meters.

This sword was very terrifying, turning into a ray of death light, flashing away, like the real speed of light, after a flash of black light, Bato Flame Demon directly turned into two halves in the run, starting from the top of his head and completely splitting into two halves under his feet, the scorching abyssal fire exploded, burning it to ashes, and at the same time a huge flame shockwave swept in all directions.

But it was Tang San's design, Bato Flame Demon's demonic heart was already full of violent power, once it was broken, it would immediately cause a huge and violent impact, a huge roar sounded, and the mushroom cloud rose and shot straight into the sky.

The Palace of the Undead bore the brunt, and in the face of the oncoming huge flame storm, the power of death in the undead knight's whole body exploded, turning into a black barrier of death power in an instant, completely covering the entire Palace of the Dead, unscathed in the impact of the huge abyssal fire.

And the demons watching around were not so lucky, many low-level demons had no resistance at all in front of the abyssal fire, and were directly burned into ashes, and the advanced demon nobles also immediately erected various spell barriers to resist the invasion of the abyss fire, many demons were startled, they didn't expect that the death of this Bato Flame Demon would cause such a huge explosion.
