The bones of these extraterritorial heavenly demons were extremely hard, comparable to the latest alloys, and even the Flame Heaven Burning Sword in Xu Dashan's hand could not cut it. If you use them to refine weapons, the power is definitely not small.

The only thing that worries people is that the Extraterritorial Heavenly Demon Divine Mind carries a strange curse power.

Qi Wentian of the Ten Thousand Ghost Palaces in the Ancient Land of Xiuzhen is an example of escape, he manipulated the Heavenly Demon Skeleton as a magic weapon, but as a result, his soul was eroded, and finally he turned into a demon.

But for Xu Dashan to come, these are not problems.

There is a yin and yang fish, and no matter how strong the divine thought curse is, it can be wiped out. With a plan in his heart, he put a few skeletons into the cave for the time being.

Next, the two of them rushed around the country of Yellow Springs, and after half an hour, they had already explored the entire space.

Matsusaka Sakura became depressed: "According to the records in the secret codex, the Yellow Spring Netherfire should be here, why is there no trace of it. Or was it taken away a long time ago?"

"Are you sure that the secret tomes are correct?" Xu Dashan asked rhetorically.

"Well, the Huangquan Netherfire sealed by the jade talisman was taken from here by the seniors of the sect, and it has been hundreds of years, so it shouldn't be wrong. ”

"Wait for me to release the sniffing gopher to try," Xu Dashan beckoned.

A strange-looking rat appeared out of thin air and chirped in horror. Clearly, it sensed that the space was filled with an aura of evil death.

"Don't be afraid, there is me" Xu Dashan patted the little guy's head and said, "Take me around to find out what's going on here." ”

"Chirp...... Chirp...... "The snorting gopher's paws kept pulling, as if to tell something.

Xu Dashan immediately understood, and nodded speechlessly: "Okay, after the matter is done, two pills!"

This guy is getting more and more presumptuous, let it do some work, dare to bargain.

To achieve the goal, the sniffing gopher jumped from the arms of its owner and carefully searched in the yin soil.

It was the first time for Matsusaka Sakura to see a mouse hunting for treasure, and she asked curiously, "Can you find it?"

"If we can't find this little guy, we'll have to go home empty-handed. Xu Dashan replied.

As soon as he finished speaking, the sniffing gopher suddenly ran wildly towards the ruined house in the distance, letting out an excited cry of joy.

The two hurriedly followed, and after a few seconds, a stone house appeared in front of them that had collapsed for an unknown number of years. The mottled stones leave traces of weapon attacks, and it is clear that there was a great battle here.

"Nothing out of the ordinary," Matsusaka Sakura said confusedly. They had already explored the neighborhood before, but they didn't find any clues.

Xu Dashan understood what the little guy meant: "In the ground!"

After speaking, he condensed his vitality and waved his hand. Hundreds of tons of stone remnants were directly wiped out, and several runestones appeared underground.

It turned out to be an isolation circle, no wonder I didn't find anything abnormal with my clair. It seems that after the predecessors of the Matsusaka Sakura Master took away some of the strange fires, they were afraid of being found by others, so they deliberately set up a magic circle to hide.

For some reason, she didn't record this incident in the secret book of the master.

If it weren't for the keen sense of the sniffing gopher, the two would have really missed it.

Xu Dashan kept his promise, threw two pills, and then sent the little guy back to the cave blessed land.

Then things become simpler, as long as the forbidden circle is broken, you should be able to find the location of the Yellow Spring Nether Fire.

With just one punch, shatter the circle.

The flat stone floor collapsed violently, revealing a large hole, and the dead and silent yin qi that had been sealed for hundreds of years came out in unison.

When the yin qi dissipated, the two of them dodged in and descended along the long, dark passage.

At the end, a huge pool appeared in front of me, and the edge was fenced with black stones.

In the center, a black flame burns.

The flame was a foot high, like lit sandalwood, which would be extinguished at any moment.

"The Yellow Springs Netherfire is about to be extinguished. This...... How is that possible?" Sakura Matsusaka was extremely disappointed. She never imagined that she would come here with all her might and almost die here, and this would be the result.

Xu Dashan took up his perspective eyes to investigate, but there was a trace of solemnity in his eyes. In the next second, he didn't hesitate, pulled Matsusaka Sakura, and quickly retreated!

Rumble...... The black flame, which was about to be extinguished, suddenly skyrocketed.

Black flames, like flowing blood, instantly filled the entire pool, boiling, and raging.

Sneer...... In the center, a ghost-like flame swooped straight at it with its bloody mouth open.

The 12 Styles of the Heavens, Shaking the Mountains!

With one punch, the void in front of him collapsed.

The creature let out a scream, and its body collapsed, turning into sparks, falling into the pool, and vanishing.

"There are ghosts in the Yellow Springs Netherfire Flame?!" Matsusaka Sakura's face was full of incredulity. What kind of ghost thing can withstand the strange fire that burns everything.

"No, it's not a ghost, it's a fire spirit! The Yellow Springs Nether Fire should have existed for thousands of years, burning day and night, so it breeds fire spirits. Looking at her appearance, it is estimated that she has just been psychic for a short time.

The strange fire had been dormant before, and our arrival had awakened her. If you can subdue the fire spirit, your strength will at least double!"

During the divine sense investigation, Xu Dashan clearly sensed the immortal and terrifying aura hidden in the black fire.

Even if it is more than ten feet away, it makes people's hearts palpitate.

Hearing this, Matsusaka Sakura was excited. Then she calmed down and shook her head: "I'm afraid I don't have the strength to subdue ......"

Her biggest reliance is the magic weapon of Magatama and the illusion space, the two are used together, even if the monks in the late stage of foundation building, if they are not careful, they will make a big mistake.

But when he encountered the fire spirit of the Yellow Spring Netherfire Flame, the black fire stored in the jade magic weapon was equal to waste, and he could only look away.

"If you don't surrender, you will fight until it surrenders!" Xu Dashan replied domineeringly.

How could a monk in the middle stage of spiritual cultivation make a small fire spirit stumped.

Thinking in his heart, Xu Dashan flew forward.

As soon as he approached within three feet, the black fire spirit swooped out again.

The twelve styles of the heavens, moving mountains and rivers, dragon elephant seals!!

Boom, boom, boom...... For a while, the entire underground palace was in flames, and the sound was loud and loud.

The fire spirit body is composed entirely of flames, and as long as the Yellow Spring Nether Fire is not extinguished, it will not collapse. But the divine consciousness that was bred was not so powerful.

After suffering a few losses, the fire spirit burrowed into the flames. No matter how provocative Xu Dashan is, it will never show its head again.

"When you are a turtle with a shrunken head, do you think I can't do anything?" Xu Dashan's divine sense moved slightly, and the Heaven Devouring Blood Jar appeared in his hand.

Immediately, a strange blood-colored flame, exuding a corrupt and evil aura, burned brightly.

"What flame is this?" exclaimed Sakura Matsusaka.

"Blood Demon Refining Fireworm, I got it from the Blood Ancestor incarnation. It is also one of the top ten strange fires," Xu Dashan explained and made a legal decision.

Bloodfiend Red Flame swooped up...... With strange fire against strange fire, I believe that the fire spirit will definitely not ignore it.

Sure enough, before the Blood Demon Refining Firefly pounced, the black fire erupted again, burning fiercely.

Two strange fires fought in the void, collided and entangled, and for a while, rolling sparks splashed everywhere, and the entire underground space completely turned into a sea of fire.

Although she couldn't feel the scorching heat around her, it made Matsusaka Sakura panic.
