Xu Qing carefully looked at the two fire spirits, and could vaguely see that there was a fist-sized purple-red spar in the heart of the fire spirit, which exuded a warm aura all the time.

As if sensing Xu Qing's bad intentions, the two fire spirits suddenly became furious and turned into an afterimage and rushed towards Xu Qing. Xu Qing only felt a flower in front of him, and ushered in the shadow of the fist in the sky. This fist shadow is not an afterimage, every fist shadow is a real existence, and the scorching aura emitted from it is so hot that even immortal cultivators dare not touch it slightly.

Xu Qing really wanted to use the Spirit Snatching Sword Technique again, when he was in Poison Flame City, he deliberately bought ten lower grade spirit swords, it is conceivable that if they were slashed with one sword, these two fire spirits probably did not even have the power to resist. But thinking of the consequences of using the Soul Snatching Sword Technique, Xu Qing hurriedly pressed this tempting idea again.

He deftly dodged to the side, preventing the two fire spirits from attacking him one after the other, and quickly activated the body protection aura, while quickly taking out a spirit weapon shield from the storage bag and protecting it in front of him.

Although Xu Qing dodged most of the fist shadows, some of the fist shadows still fell on the spirit weapon shield, and the huge force made Xu Qing retreat in the air again and again.

After dodging the first round of attacks, Xu Qing was naturally unwilling to be beaten all the time, he took out the top-grade spirit sword from the storage bag, injected the true yuan into it, and then the spirit sword turned into a streamer and slashed towards one of the fire spirits. Immediately after that, he took out a lower-grade spirit sword from the storage bag again, and the spirit sword slashed towards the other fire spirit several times, and dozens of sword qi burst out from the spirit sword and turned into a sword net, advancing in the direction of the other fire spirit.

The top-grade spirit sword was extremely fast, and it instantly slashed above the body of the fire spirit. Although the fire spirit tried his best to dodge, one of his arms was ruthlessly cut off by the spirit sword. After the arm was cut off, it suddenly turned into a ball of flames and slowly disappeared into the air. Leave no traces.

The other fire spirit was much luckier, the speed of the sword qi net was not fast, it easily dodged it with its dexterous body, and the sword qi net collided with the stone wall in the distance, and the stone chips flew for a while.

The fire spirit that lost its arm did not suffer as much as it had imagined, and it quickly landed on the lava and stood on the waves. In Xu Qing's stunned eyes. A pillar of flame quickly condensed from the magma, which was sucked into the mouth of the fire spirit, and continued to increase as the flames were devoured. The fire spirit's arm condensed again, the same as before.

"This is simply an immortal body, how can you fight in magma?" Xu Qing blinked, and he already had the intention of giving up in his heart.

But even if he wanted to give up. But those two fire spirits would not agree to let Xu Qing go like this.

And so the fierce battle began again. Every time Xu Qing injured one of the fire spirits, the other fire spirit would protect it and help it recover from its injuries quickly.

However, after a long period of observation, Xu Qing is no longer afraid. Although these two fire spirits have the strength equivalent to the middle stage of foundation building, because they have no entity, both their attack power and defense power are much weaker than ordinary middle stage foundation building monks, as long as Xu Qing is willing, he can forcibly break through and leave at any time.

There is no more fear in the heart. At this time, Xu Qing naturally did not leave, after observation. He had finally discovered the fire spirit's weakness. Every time he attacked the Fire Flame Crystal in the heart of the Fire Spirit, the two Fire Spirit would choose to dodge it immediately, not daring to force it at all, and it was obvious that the Fire Flame Crystal was their weak point.

Now that he knew the weakness of the fire spirit, Xu Qing naturally didn't want to waste any more time, and the spirit sword in his hand went to one of the fire spirits at the same time, with the lower grade spirit sword in front and the top spirit sword behind.

Seeing that the opportunity could not be missed, the other fire spirit immediately attacked Xu Qing, while Xu Qing only dodged with his dexterous body, only entangled it and prevented it from supporting the other fire spirit.

The lower grade spirit sword pointed directly at the heart of the fire spirit, and the fire spirit hurriedly flashed to the side, but the top spirit sword that followed closely behind the lower grade spirit sword suddenly appeared in the frightened eyes of the fire spirit at this time, as if it had already predicted the escape route of the fire spirit, and went directly to the heart of the fire spirit.

At this time, the fire spirit couldn't dodge, and in the blink of an eye, the spirit sword hit the fire crystal at the heart of the fire spirit. With a crisp sound, the spirit sword shot backwards, and the fire spirit's body trembled violently, and after a moment, its body suddenly collapsed.

But in the next moment, those flames condensed again, and the fire spirit appeared in front of Xu Qing's eyes again, but at this time, the fire spirit had obviously been hit hard, and the flames around him were also much dimmer, like a candle in the wind, bright and uncertain. Although it was wounded, it did not absorb the flames in the magma as before.

"The strength of the fire spirit should be determined by its spirituality, and its spirituality is hidden in the fire crystal, only by hurting its spirituality can it be injured, but the fire crystal is hard and abnormal, and the damage through the fire crystal is not large. Xu Qing frowned and thought about it, wanting to find a better way.

Xu Qing's eyes lit up slightly, he put the top-level spirit sword back into the storage bag, and then took out a giant axe spirit weapon. Although the Giant Axe Spirit Weapon is not sharp enough, it will produce a strong concussive force when attacking an object, so it is really suitable to destroy the spirit in the Fire Flame Crystal.

The True Yuan slowly poured into the Giant Axe Spirit Weapon, and then it was raised high, slashing down at the uninjured Fire Spirit with the momentum of opening the mountain. The fire spirit couldn't dodge, and the giant axe spirit weapon was directly cut off from its shoulder, and landed on the fire crystal without any barrier, and the huge force of the shock made the giant axe violently vibrate.

A scream came from the fire crystal, and it stopped abruptly after a moment, and the fire spirit's body suddenly collapsed at this time, turning into flames and disappearing into heaven and earth.

The flame crystal fell from the sky, and Xu Qing's spiritual power spit slightly, and he sucked it into his hand. As concocted, Xu Qing quickly solved the other fire spirit and obtained a fire crystal again.

The flame crystal is purple-red, and it looks very positive, although it is condensed by the essence of fire, it does not feel hot at all when held in the hand, and it is very warm. Even if he didn't have to perceive it carefully, Xu Qing could still feel the surging fire attribute spiritual power contained in the Fire Flame Crystal, which was much stronger and purer than the Spirit Pill.

"It seems that you need to hunt some fire spirits, this is a good thing, and you won't even need to do alchemy in the future. Xu Qing thought in his heart, and then found a safe place to start pranayama and restore the consumed spiritual power.

Three hours later, Xu Qing's spirit and spirit returned to its peak again, and the true yuan in his body was surging like a tide, strong and powerful. Because when he was entangled with the fire spirit before, his clothes were already a little torn, so Xu Qing changed into a purple robe.

The purple robe is dusty, full of elegance and dignity, Xu Qing is like a fairy king walking in the world, with an ethereal temperament, and there is a fairy rhyme flowing between gestures.

Searching for the Fire Grass was very boring and tedious, but Xu Qing had to devote himself to it again, he had a strange poison in his body, so he couldn't help but look for the Fire Grass hard, he continued to explore the depths of the passage. (To be continued.) )
