At the entrance of the mine, Elder Lan looked at the pitch-black mine, his brows furrowed deeply.

"Elder, will these guys find a secret when they enter the mine?" asked a monk in the early stages of foundation building, cautiously beside him.

Elder Lan shook his head slightly: "These people don't need to worry, they can't escape, but that guy who escaped with the Void Talisman is very troublesome, and it is likely that the secret here will be exposed to the Zhenyuan Sect to know!"

In the early days of foundation building, the monks couldn't help but be stunned.

"There's no way that man could have discovered the secrets of the mine!"

Elder Lan snorted: "What do you know, just a rotten silver vein, but we have arranged so many monks to guard it, this in itself is a loophole!"

"That'...... What are we going to do next?" asked the early foundation monk.

"Destroy these guys in the mine first, I hope this matter will not attract the attention of the Zhenyuan Gate, but for the sake of insurance, I still have to inform the master of what happened here, Ma Liang, this matter will be handed over to you, and I will report to the master immediately!"

"Yes, Elder!" replied another late-stage foundation building monk as he bowed down and took out the Messenger Jade from his storage bag.

Elder Lan glanced at the pitch-black mine, and his face was murderous: "The others followed the old man into the cave, and this group of guys must be wiped out one by one!"

More than a hundred monks followed Elder Lan, each offering a defensive magic weapon and a protective light shield, and then quickly poured into the mine.

The remaining three hundred Qi Refining Stage cultivators remained outside the cave......

......

In the mine cave hundreds of meters away, Xia Yin took Zhang Rouran, followed closely by Lin Yuan, Zhou Wu and more than twenty Qi refining stage cultivators, and went all the way down the pitch-black mine cave.

Although there is no light in the mine, everyone is a monk after all, and their eyesight is far beyond ordinary people, and the impact is not very great.

To Xia Yin's surprise, there was not a single miner in the mine.

However, this thought only passed through my mind......

The most important thing now is how to escape and save your life.

Today's Xia Yin has become the backbone of this group of people, even Lin Yuan and Zhou Wu dare not leave Xia Yin, otherwise once they encounter the group of monks of the Armor Breaking Sect, they will definitely die!

Suddenly, Zhang Rouran, who was tightly pulled by Xia Yin, suddenly leaned his head to Xia Yin's ear and whispered: "This vein is strange!"

Xia Yin couldn't help but be stunned, but he didn't stop at all, but he used his spiritual power to sound a voice in Zhang Rouran's soul consciousness: "What, find out what's wrong?"

Zhang Rouran leaned into Xia Yin's ear again and whispered: "The surface of this vein is a rotten silver mine, but deep underneath the rotten silver mine, I sensed another rare ore vein!"

"What kind of rare mineral deposits?" Xia Yin asked with some curiosity.

"If I'm not mistaken, this is an extremely rare vein of Breaking Stone!"

Xia Yin clearly sensed that when he said this, Zhang Rouran's tone was full of surprise.

"What, is this Boundary Breaking Stone valuable?"

Zhang Rouran nodded slightly, kept his head in Xia Yin's ear, and carefully told Xia Yin about the Boundary Breaking Stone.

The Boundary Breaking Stone is a kind of spatial attribute material, and it is a very high-level kind, it is impossible for ordinary monks to know about it, but those high-level old monsters regard the Boundary Breaking Stone as a treasure!

If you can obtain the Boundary Breaking Stone, and add some crystals, rotten silver essence and other materials, you can use it to repair various spatial items, such as teleportation arrays, large star ships, and some spiritual weapons with spatial attributes......

The most important thing is that the Boundary Breaking Stone Milk derived from the large Boundary Breaking Stone Vein can repair the Void Spirit Body!

Zhang Rouran's last sentence shocked Xia Yin, and then his face was full of surprise.

"Great, then the boundary-breaking stone veins deep underground, has there been any derivation of the boundary-breaking stone milk?"

Zhang Rouran nodded slightly: "I sensed the breath of the Boundary-Breaking Stone Milk!"

Xia Yin couldn't help but suddenly realize.

"I see, no wonder the Armor Breaking Sect has sent so many monks to guard this place, it seems that they have also discovered the Boundary Breaking Stone vein deep underground!"

Zhang Rouran continued to whisper: "The Boundary Breaking Stone Milk is too important to me, you have to find a way to block the others and the Armor Breaking Sect monks, let me sneak into the depths of the mine alone, try to get the Boundary Breaking Stone Milk, and directly take the refining, if the amount is enough, my Void Spirit Body will hopefully recover, and at that time, I will have countless ways to let the two of us leave this place safely!"

Xia Yin didn't expect that this mission would have such a great harvest, and his spirit was doubled in an instant.

"No, you just said that the Boundary Breaking Stone vein is deep underground, how can you reach the depths of the earth alone?"

Zhang Rouran smiled: "Don't forget that I'm a virtual ...... Of course there is a way!"

Xia Yin nodded slightly: "Okay, then you be careful yourself, if you can't do it, don't force it, safety first, I will try to drag everyone, including the Armor Breaking Sect monks!"

Zhang Rouran nodded.

Xia Yin let go of the hand holding the girl, and then stopped his steps.

But Zhang Rouran directly sacrificed the jade boat and flew towards the depths of the mine......

This cave, because a large amount of rotten silver ore has been mined, appears to be very wide, and various forks are crisscrossed vertically and horizontally, and the terrain is very complicated.

"Hey, Zhang Daoyou, Sister Ling, this is ......"

Lin Yuan found that Zhang Rouran continued to go deeper, while "Zhang Hao" stopped his pace and couldn't help but ask suspiciously.

Xia Yin raised his hand and motioned for everyone to stop: "There is always an end to the mine, it's not a way for us to keep running inside, we must try to block the monks of the Armor Breaking Sect, the reason why I let my sister continue to move forward is because I don't want to be distracted!"

This explanation makes sense.

Zhang Rouran's sixth-layer cultivation of qi refining really can't help much, having him will distract "Zhang Hao" instead.

"So what do we do now?"

Lin Yuan looked at Xia Yin and asked a little anxiously, because the voice of the Armor Breaking Sect monk was already coming from behind him.

Xia Yin groaned for a while, and said to Lin Yuan Zhou Wu and the twenty Qi Refining Stage cultivators, "You all come behind me!"

At this time, everyone naturally obeyed Xia Yin's words unconditionally, and came behind Xia Yin one after another.

Xia Yin wiped the storage ring off his arm and placed it at the wrist position, and between the meager mana in his body, countless low-level talismans burst out from his wrist......

After having mana, even if it is only a meager mana, it is enough to perform the long-lost low-level talisman technique.

Everyone saw the sky full of talismans flying, thousands of them, all gathered on the wall of the mine cave fifty meters in front of Xia Yin.

At this time, the figures of Elder Lan and the others had already appeared in the place where the talismans were densely packed.

"You can't escape today!" Elder Lan's confident voice sounded in the mine, ignoring the countless low-level talismans around him.

However, at this time, Xia Yin's hands turned sharply like a windmill, quickly pinched the law decision, and then hit dozens of law decisions in a row......

Snort!

Thousands of talismans instantly ignited, turning into countless ice pick fire bombs, which exploded one after another, turning into a dense aura of water and fire......

Xia Yin waved his hands continuously, and quickly sent out dozens of wind blades, shooting into the aura of water and fire that filled the mine in front of him......

This scene made Lin Yuan, Zhou Wu and others couldn't help but be full of doubts.

"Zhang Hao" Daoyou, what are you doing?

Elder Lan and the others, who were in the aura of water and fire in front of them, also looked at Xia Yin with a vigilant face, and the body protection shield on their bodies was fully opened.

This group of people is very puzzled, this guy wants to use these dozens of low-level wind blades to attack, this is too naïve!

The answer was soon revealed!

The breath of water and fire that filled the mine suddenly exploded at the moment when dozens of wind blades shot in!

Boom Boom Boom ......

A strong wave of qi erupted towards the front and back ends of the mine in this confined space!

Lin Yuan Zhou Wu and the twenty rookies in the Qi Refining Period, even though they were protected by the body protection shield and magic weapon, were still swept up by the qi wave and threw out towards the depths of the mine......

And Xia Yin had already turned into an afterimage at the moment when the qi wave erupted, shooting towards the depths of the mine, and the speed was even faster than the people set off by the qi wave!

At the other end of the mine, there was even more chaotic exclamation and curse from the monks of the Armor Breaking Sect......

The next moment, only a loud bang was heard, and where the explosion had just occurred, most of the mine cave collapsed directly, cutting off Xia Yin and the others from the Armor-Breaking Sect monks......

When Lin Yuan and Zhou Wu got up after rolling on the ground for more than ten zhang, they saw the scene of the collapse of the mine.

These two people did not suffer much damage because they had magic weapons and body protection shields to protect their bodies, but the twenty rookies in the Qi refining period were generally directly stunned by the qi waves, and even three of them flew into the raised stone wall of the mine cave and were seriously injured.

This is Xia Yin deliberately sacrificing thousands of talismans fifty meters away from this group of people, otherwise the consequences will be even more serious!

For example, the monks of the Armor Breaking Sect must have had many people injured under the explosion of the talisman......

"Ah...... The way out is cut off, how can we get out?" Zhou Wu couldn't help but be a little anxious.

Xia Yin looked at this guy a little speechlessly, and then said coldly: "Let's think about how to block the attack of the Armor Breaking Sect monk first, if Zhang Mou's guess is right, they will soon open the mine and attack in!"

Zhou Wu was speechless.

Xia Yin looked at the dozen or so Qi Refining Stage cultivators who had just gotten up, and ordered, "You guys help the injured Daoist friends up and get some healing pills for them to take!"

Seeing the dozen or so Qi refining rookies busy helping up the injured Daoist friends on the ground, Xia Yin sighed secretly in his heart.

These people are already doomed to death!

The Armor Breaking Sect would never let anyone go, lest the news of the Boundary Breaking Stone Vein leak out.

Even if it was himself, he could only hope that Zhang Rouran would be able to find enough boundary-breaking stone milk, restore the Void Spirit Body, and then use the space secret technique to move the two out.

And for others, there is no other way but to die!

Even if Zhang Rouran had the strength to bring these people, she would not allow him to do so, unless she was absolutely sure to hide from this group of people.

After all, the girl's void spirit body is a secret that must not be revealed, and it cannot be leaked because of soft-heartedness!

I never think that I am a good person, and I will never make a "heroic" feat of sacrificing myself to save others.

Compared with the lives of a group of people who have never known each other, the safety of himself and Zhang Rouran is much more important......

And what he has to do now is to drag the Armor-Breaking Sect monk and let Zhang Rouran have enough time to obtain the Boundary-Breaking Stone Milk.

As for how long Lin Yuan, Zhou Wu and the others can live, they can only resign themselves to fate!

Just when Xia Yin was in a complicated mood, there was a muffled sound from the collapsed mine, and the messy gravel continued to roll......

The Armor Breaking Sect monk really started to act on the other side.

With the strength of this group of people, it won't be long before they will penetrate this collapsed mine and kill again!

Xia Yin couldn't help frowning again.

I don't know how deep this mine is, and I must not continue to go deep into the mine, otherwise once I reach the deepest depth, Lin Yuan and the others are likely to discover Zhang Rouran's abnormal behavior......

But if you want to stop more than a hundred foundation building monks, how easy is it!
