It's still that question, although Shi Lu's spiritual power is attributeless, but after all, it is still cultivated by individuals, and it is okay to use it temporarily, and it cannot be used for refining, although the spiritual power of the dark night can be refined by Ning Xu due to the same root and origin, but the three energies of flame spiritual power, ice spiritual power, and attributeless spiritual power cannot exist in Ning Xu's body at the same time.

This will cause too strong oppression to Ning Xu's body, and if Shi Lu is withdrawn, it will be even more unrealistic for the two people to take the top, with the support of the spiritual power of the baron-level Shi Lu, they can only barely resist the undead plague by flooding, not to mention that Ning Xu and the two are only knight-level cultivators.

In either way, it would be unrealistic to expect two knights and a baron to withstand such a plague that could destroy a city for a long time.

This kind of thing can only be fought by high-level professionals, or large-scale professionals in a formation with the mode of war, as for ordinary people, or technological weapons, in the face of this kind of attack with dimensional power, it is useless, just a burden.

"Bang bang bang." Several more successive explosions sounded, and the tentacles in the flesh hall continued to explode, and the rich yellow-green sea continued to spread like an ocean.

The undead plague instantly rolled up a wave, like a tsunami that flooded the world, and rushed towards the Nirvana fire wall that was already a little lonely in the undead plague.

A large amount of spiritual power was fed into the wall of fire, and the flames continued to burn as if they had been poured oil, but even so, it was still difficult to resist the undead plague that was pounced.

Ning Xu could clearly feel that the Nirvana True Fire in the wall of fire was constantly being extinguished little by little, even if he had spiritual power, it could only alleviate this situation, not change the result.

"I can't stop it, and I'm ready to deal with the first wave of the undead plague."

"You can't give up, you have to block it, otherwise you ...... outside the city"

"Gan, don't be outside the city, don't delay the spread of the undead plague, you know it in your own heart, and if it continues like this, we will die here because we don't have enough spiritual power to protect our bodies."

Ning Xu was originally a little anxious, but after hearing Shi Lu's words, his emotions exploded instantly, and he yelled desperately, and the amplitude of the spiritual power output in his hand began to decrease continuously.

"Heroic Bears, Spell Cards, Rock Barriers."

Shi Lu also knew in his heart, he roared angrily, reluctantly withdrew his hand, reached out and grabbed a card with the word Heroic Spirit written on it from the air and slapped it on his body.

The bear fur continued to cover his body, Shi Lu raised his hands and pressed to the ground, and the rich yellow light continued to pass from his body into the floor, and a yellow light filled the place where the flames were burning.

"Boom!" The wall of Nirvana fire burst open suddenly, and Shi Lu roared, and from the earthy yellow light, an incomparably solid stone wall was drilled, and the stone wall flashed with gray-white light, faintly reflecting a bit of metallic color.

Ning Xu raised his hand and waved, and a flame erupted, incinerating a wisp of undead plague that had been lucky enough to escape.

"Night, Frost Shield, the stone wall can't hold up for too long, give me a few minutes!" Ning Xu roared angrily, and the Nirvana True Fire in his hand quickly condensed in his hand, forming threads of flames, and behind him, a golden aura slowly emerged.

"Frost Shield." Three blue rays of light fell on the three of them almost at the same time, condensing into a miniature shield that enveloped each of them.

"Click." A faint but incomparably clear voice came out, and Shi Lu's face suddenly swelled up with a pale, and his spiritual power was almost uncontrollable surging towards the stone wall.

The previous sound seemed to be just a signal, and then, a series of rings sounded continuously, and cracks like spider webs appeared on the surface of the stone wall, and wisps of yellow-green gas kept spreading outward.

"Frost!" Styx let out a low cry and pressed his hands on the surface of the stone wall, and the wisps of smoke poured out of the cracks, and after touching the shield, the shield kept rippling.

The blue ice swelled up from the place where the palm of the night came into contact with the wall, and continued to flow towards the wall, and the blue ice flowed with the power of nirvana, which was full of vitality.

The frost sealed every crack in the wall, but even the plague of the undead that had infiltrated it was rapidly draining the spiritual power in the body of the night.

Behind the two of them, in Ning Xu's hands, the crimson flame flickered, and the flame threads kept shuttling between his palms, as if they were about to weave into a thing, but for some reason, every time a little rule appeared, that thing would collapse directly, and the aura suspended behind his head flashed and bloomed, and there was a figure standing in the aura.

Dressed in white, carrying a long sword, surrounded by an endless sea of fire, there is only one person who can have a relationship with Ning Xu, Yan Jun and Ning Lou!

"Whew!" Ning Xu closed his eyes slightly, and his consciousness sank into the sea of souls, at this time, the sea of souls had turned into a sea of flames, and the phoenix covered in flames fluttered its wings and soared in the sea of fire, and in the center of the sea of fire, a thing like a token was quietly suspended above the flames.

The token continued to devour the flames in the sea of souls, and then black and yellow divine fire flowed out of the token.

There are a few big characters on the token, even in the sea of fire, the characters on the token are still very clear, but even so, as long as people's eyes are focused on the characters, there will be a feeling of dizziness constantly coming to mind, it seems that the characters have a little divine power.

"Damn, this method taught by my brother is very powerful, but I don't think I can hold it now."

The moment the golden token in the sea of souls appeared, the flame thread, which was still a little disordered and at a loss, immediately found its direction and converged towards the center of Ning Xu's palm.

The flame threads were intertwined and intertwined, and the red light suddenly shone brightly, like a small sun, held in Ning Xu's hand, blooming with an incomparably blazing high temperature.

The moment that fireball appeared, Ning Xu instantly felt an extremely powerful force spread out from that fireball, as if it was about to push his hands away, and then, completely burst.

"It's too dangerous." While thinking so in his heart, but the movements in Ning Xu's hand were not slow at all, the spiritual power that had been depleted because of the support for the Nirvana True Fire, the moment the token appeared in the soul sea at this time, it frantically surged out of the dantian, and it seemed to be completely endless.

In the void and dim aura behind Ning Xu's head, a whirlpool emerged, pulling the surrounding aura, constantly going to the inside of the whirlpool, between the whirlpool constantly rotating, the violent power instantly tore the aura to pieces, and then the dross in the aura was thrown directly out of the whirlpool, leaving only the purest point.

That bit of spiritual energy essence was extremely pure, and it was quickly infused into Ning Xu's dantian, but with a slight turn of spiritual power, that thing was instantly refined into a large amount of spiritual power, which was replenished into the meridians.

This is also the reason why only when you reach the marquis level can you unscrupulously release spells, whether it is the law golden pill or the law aura, they will take the initiative to help their owners absorb energy, and after refining it, it will be directly injected into the master's body to provide a steady stream of supplies.

So much so that unless the marquis level kills it instantly at the beginning, with the law golden pill and the law aura, they can have almost endless energy, and a marquis can be killed by losing to the opponent in battle, but he will definitely not be consumed to death because of excessive consumption.

Unless it's in the Nine Shadows, or in the Necromantic Realm, where the aura is thin and there is almost no way.

Although Ning Xu is not a marquis, just a small black iron, but with the support of Ning Lou's power, this law from the previous deprivation from the Wu family's powerhouse can also play a role in extracting aura.

Of course, since that aura is supported by Ning Lou's strength, most people will think that this law aura is just a little bit of law breath lent out by Ning Lou, although there is no precedent, but this kind of genius has a few slapstick operations, isn't it normal?

The spiritual power gathered in his hand, Ning Xu's hands slowly closed, and the powerful spiritual power instantly forcibly pressed the flame token from unstable to stable state.

It's just that the already unstable flames, how can they stand like this? A huge flame power continued to drill out from inside, resisting the spiritual power in his hand.

Although it has the protection of spiritual power and is friendly with the flames of Yan Feng, where can the flames in the berserk state manage these? The blazing flames continued to scorch Ning Xu's palm through spiritual power.

In just an instant, the palm of his hand began to dry up a little, and if he could not still feel the vitality flowing in that palm, he would have thought that his palm had completely reduced to a piece of black coal.

The violent flame flow passed through the surface of his skin, divided into countless filaments, and rushed towards his meridians, and in each meridian, the huge conflict between spiritual power and flame made Ning Xu extremely painful.

The huge pain in the palm of his hand and the bursts of burning sensation that poured out from almost every part of his body constantly stimulated Ning Xu's nerves, but he couldn't put it at the moment, and he couldn't let it go.

That flame creation has a faint tendency to get out of control, and once it is given up at this time, that thing will explode, and everyone else will have to die here.

"Ahh Ning Xu roared angrily, the Nirvana True Fire continued to weave in the palm of his hand, a wisp of gold was revealed from it, and the delicate phoenix head symbol appeared on the token, exuding bursts of aura belonging to the Nirvana True Fire.
