It's just that in the face of these fist-sized holes, Yun Yu couldn't help but be speechless, although this hole is dense, it is obviously extremely far-reaching.

Being in the underground, he didn't dare to use the Earth Escape Technique to enter the tiny holes in the stone wall, because the rocks in this place were a special species, not ordinary soil attribute bulking properties.

And if you want to sacrifice spiritual power to blast these holes, under such circumstances, it is definitely not a wise move.

Standing on the spot, Yun Yu couldn't help but show a look of concern on his face. After a while, he turned around and left the cave and walked directly towards the cave where the demon monks had been.

According to Yun Yu's assumption, no matter where the nest of the Heavenly Fire Glowworm was, there should definitely be a passage to enter there, otherwise those Heavenly Fire Glowworms would not be able to dig out those holes in the stone wall alone.

If there is a passage into the final nest of those Heavenly Fire Glowworms in the underground caverns here, according to Yun Yu's assumption, apart from the tall stone platform, there will be no other place.

Quietly entering the vast cave, Yun Yu's soul power probed, and on the stone platform, he did not find the figure of the demon cultivator.

In the vast empty cave mansion, there was no abnormal fluctuating aura. And the long stone is still hanging above the stone platform.

Under the protection of the breath charm, Yun Yu slowly approached the huge stone platform, and probed the long stone up close, and his eyes suddenly showed a look of shock.

The long strip in front of him, why did it give him a rather familiar feeling since before, it turned out that the main material of this long strip of stone was made of the entire 10,000-year-old black yin soul wood.

And it is not a simple 10,000-year-old ghost wood, but it has evolved into a fossil after hundreds of millions of years, no wonder it was not remembered before.

At the beginning, in the cultivation world, the statue given by the Venerable Master Ruoyi was carved from this wood, but this is a more precious and rare fossil.

At this moment, there was such a huge 10,000-year-old Yin Soul Wood fossil in front of him, which made Yun Yu also very surprised.

"Hahaha, your junior is really daring, he dares to go and come back, and he still wants to beat the old man's idea of sealing the soul with this strange treasure, it seems that you have really lived to the end. ”

Just as Yun Yu was hanging near the tall stone platform, looking at the long stone in the sky, suddenly a wild laugh suddenly sounded in the distance.

A figure wrapped in black mist, from the depths of the cave in the distance, rushed like a lightning speed, and it only took a few flashes to get closer.

The figure of a child who looked no more than thirteen or fourteen years old was revealed.

"You can actually see through Yun's breath talisman?" Suddenly, the demon monk stared at the place where he was hanging, and Yun Yu's complexion changed suddenly.

The breath talisman is not a rare thing in the spiritual world. But after all, it is a high-level special talisman, and after Yun Yu created and refined it himself, its breath collection effect is undoubtedly extremely clever.

According to Yun Yu's assumption, the breath charm he drove at this time was difficult to see through even a late-stage cultivator of the Xuanling Realm.

But the demon monk in front of him not only recognized the location of his figure, but also in a very distant place, and had already penetrated his stealth effect.

At this time, Yun Yu was by no means afraid of the appearance of the demon monk, but he was surprised that the other party could break his body in one fell swoop.

"Breath Talisman, Hmph, with a talisman, you want to fool the old man in front of him, you think too easily.

Don't you know that as a demon cultivator, you are extremely sensitive to the existence of any trace of soul power?" The child-like demon monk looked at Yun Yu with an expression of extreme disdain.

At this moment, the demon monk, although he is a child's body, and his voice is only in the state of youth, but his tone and demeanor seem extremely old-fashioned, and he regards Yun Yu as a junior.

The demon monk's words made Yun Yu's heart suddenly. As a Yin attribute energy cultivator, he was naturally very sensitive to the cultivator's Yuan Soul spiritual energy and breath fluctuations.

Although the breath talisman is powerful, it can also shield the spiritual power and divine soul aura of the monk's own body, but a small wisp of soul breath fluctuation of the talisman itself is still a little outward.

Hearing the demon monk say so bluntly, Yun Yu's heart was greatly relieved. It turned out that it was not the failure of the effect of the breath charm, which was undoubtedly the most beneficial thing for him.

"Ah, is that tower-like thing in your hand the Meritorious Receiving Tower? Could it be that Xu Xiuyou and Qu Sen Xiuyou fell into your hands at this time?"

Just when Yun Yu wanted to talk to the demon monk in front of him about something, suddenly a small tower-like object that the demon monk was holding in his hand came into his eyes.

As soon as he saw the tower-like thing, Yun Yu's face suddenly changed in shock, and an exclamation came out of his own voice.

"There are only two juniors at the spiritual realm level, even if they have a powerful secret treasure in their hands, if the old man wants to capture and kill, will he still be able to waste his energy.

This secret treasure tower is also a powerful offensive and defensive weapon, but it is a pity that the effectiveness of those previous attacks has been damaged, otherwise its power will definitely be able to exert its full strength in the hands of the old man. ”

Standing on the spot, the demon monk with a childlike face didn't care about playing with the Gong Receiving Tower, which was only the size of a broad bean, and his face showed a hint of joy.

The power of this secret treasure attack was powerful, and although he was in the seal of the combination formation prohibition at the beginning, the power of that power still made him a little jealous.

Otherwise, it would be impossible for him to sacrifice the Heavenly Fire Spiritual Liquid that he had refined for many years to resist the attack that devoured the energy of nearly 10,000 needles of silk thread.

It was precisely because of this that when the energy of nearly 10,000 needles of mango silk thread exploded and destroyed his Heavenly Fire Spiritual Liquid, he knew how powerful the energy contained in his attack power.

"You killed Xu Xiuyou and Qu Sen Xiuyou?" Although he had already made a judgment in his heart, hearing that the demon monk confirmed it, Yun Yu still showed disbelief.

Xu Zhengmao is comparable to the cultivation of the Xuanling realm, and Qu Sen is not only the cultivation of the peak level of the spiritual realm, but also hidden in the internal formation of the Gongshou Tower.

Although the demon monks in front of him had extremely strange methods, Yun Yu really couldn't believe that he wanted to easily kill such two monks.

But after only a moment's hesitation, Yun Yu's heart suddenly shook that he had already contacted the key to this matter.

The demon monk in front of him was not alone, his companion insect had tens of thousands of heavenly fire insects, but he was included in the meritorious tower by Xu Zhengmao.

With tens of thousands of Heavenly Fire Glowworms inside the Gongshou Pagoda to launch an attack, it is also very possible to act in concert with the demon monks.

"The old man is very curious, since you broke the prohibition of the cave, why wasn't you killed by the spirit insects guarding the cave?

The demon monk didn't mean to say anything more, but looked at Yun Yu with a little puzzlement in his eyes, and said solemnly.

While staring at the place where Yun Yu was, his hand kept driving the Yuan Soul Power in his body, constantly residing in the Gong Receiving Tower.

As two hostile parties, one is a spiritual realm cultivator, and the other is an old monster of the special martial arts Xuanling realm, in this dark underground cave place, no one even took the lead.

The most bizarre thing was that the Spirit Realm Monk was obviously on the extremely weak side, but his words and stance did not show even the slightest hint of fear and panic.

"If you want to meet Yun's companion, you just want to get her secret treasure, so naturally you can, but Yun wants to learn your methods again. ”

At this time, Yun Yu still didn't think about asking the Spirit Ring Fairy to appear and join forces with him to fight against the demon monks. Instead, he looked at the monk in front of him with all his heart, and had the intention of fighting him head-on.

It was not that Yun Yu Yun Yu was arrogant, but he knew that the other party must still have a large number of Heavenly Fire Flying Insects, and at this time, the other party was holding the Gong Receiving Tower, and there were about tens of thousands of spirit insects among them.

Even if the Spirit Ring Fairy appeared, it would be difficult to help him much. On the contrary, some of his methods could not be used in time.

And although the lightning leech is powerful, he can't control it like his arm, as long as he releases it, except for himself, everyone else can be said to be among the targets of the lightning leech.

Previously, he was under the cave, and with Yun Yu standing in front of the Spirit Ring Fairy, he naturally wouldn't let the lightning leech attack the Spirit Ring Fairy, but if the three of them were fighting, it would be difficult for him to pay attention to the Spirit Ring Fairy all the way.

Hearing Yun Yu say this, the Demon Monk's expression was also slightly stunned. At the beginning of the fight, although the two sides were only a head-to-head blow in the real sense.

That is, he cast the Void Domain Secret Technique, and his hair turned into a snake energy attack, but the young monk in front of him could easily break that blow.

At this moment, he dared to argue with him alone, which made the already suspicious demon monk's heart move slightly.

Although his secret is powerful, the most powerful thing is that his defense is extremely strong, and although the energy silk attack is powerful, the other party has already seen it.

Since the other party dares to challenge head-on alone, he naturally has the means to fight against this secret technique.

"If you want to kill a junior in the middle of the spirit realm, where is the need for the old man to do it himself, you can fight with the old man's spirit worm first. ”

As a demon cultivator in the realm of Xuanling Realm, saying such words made Yun Yu Wendu couldn't help but laugh in his heart. If the other party is completely sure, there is naturally no need to sacrifice the spirit worm.

Although the Heavenly Fire Glowworm is powerful, if it is used in battle, it will be the result of injuring 1,000 enemies and 800 self-damage, and every time it is used, there will inevitably be losses.

"Hahaha, this secret treasure has finally been preliminarily practiced by the old man. ”

Just as the demon monk answered the words, he was about to instruct the Heavenly Fire Glowworm hiding in the secret cave, but he suddenly laughed with a happy face.

As its laughter sounded, a buzzing sound suddenly sounded, and I saw that the green mangs of the bean-sized Gongshou Pagoda were blooming, and they were quickly activated and formed into a body of more than ten zhang in size.

Under the sudden flash of the tall tower, a swishing sound suddenly resounded on the spot. Tens of thousands of dark red skyfire glowworms suddenly shot out from the lower end of the tower.

A red cloud of insects was suspended in the air, and just as tens of thousands of Heavenly Fire Glowworms appeared, a silver figure also flew out of the tower quickly, and with a flash, it shot towards the place where the cloud feather was.

The appearance of this figure was so rapid and unbelievable that the demon monk, who was rejoicing greatly, couldn't help but be stunned by the scene in front of him.

He also did not expect that the monk with the tree-like imitation spirit weapon had actually hidden in the Meritorious Receiving Pagoda in advance and was not discovered by him.
