"Under the fire?" he repeated the phrase.

Suddenly, his eyes lit up, and he said in his heart, "Could it be that the original five-system prohibition in this wooden tower is only guarding, not offensive, only the addition of the back, that is, the current fire attack and iron plate barrier are added later." ”

I don't know when the original ban was laid down, obviously it was not something that Lao Mai could break quickly, but the fire on the fire that was added later was made up of the dog's tail and mink of those who were now in the foundation building period outside, and he thought about it again and again, and finally confirmed this.

The formation ban laid by the Great Perfection during the foundation building period, there is no doubt that the early stage of Jindan can be broken, Lao Mai has advanced to Jindan Avenue, this news is only known to Mu Qingzi, at that time, Lao Mai pressed down, and he didn't want to celebrate it as a well-known person, and it was just such a day to prevent it.

Lao Mai has advanced to the Jindan stage, which is a point that the group outside missed, otherwise they would not dare to do this, a group of foundation building period Dacheng besieged a Jindan early stage, even if the Jindan early stage was outnumbered, no matter what, they could escape.

Lao Mai had already figured it out, so he swung the small stone ball in his hand and threw it into the ground, smashing the floor sawdust sideways, revealing the dark cast iron layer underneath.

He used his divine sense to feel it for a while, and then he felt that although the cast iron layer under the ground was thick, it was newly clothed, and it was only made during the foundation building period, and it should not be difficult to penetrate the Jindan period.

Lao Mai then divided the small stone ball into three black stone drill bits, which can be compared to diamond drills, pinched a few hands and used the endless trick, and carried five or six successful waves and smashed them down.

I saw a whistling sound followed by the sound of rolling drilling, and the three drill bits hit one and drilled straight into the underground cast iron layer.

After exhausting his strength, Lao Mai stretched out his head to look in, and it was estimated that he had drilled more than one meter, but he had not drilled through, so he summoned back three drill bits, waved his hand and drilled into it again, and this time he drilled into more than one meter, but he still did not go to the end.

Lao Mai couldn't help but smack his tongue a little, you are thick enough, thought about it, beckoned the drill back into his hand, transported ten successes, and shouted in his mouth, "Destroy endlessly!"

With a buzzing sound, three drill bits rolled and collided, and suddenly drilled into the small hole more than two meters deep in the cast iron layer.

Suddenly, he heard a popping sound, Lao Mai hurriedly recruited back the drill bit to see, the drill bit was glued to some red clay, and he was overjoyed, it turned out that he had drilled through the cast iron layer and reached the laterite layer.

Laterite is a layer rich in iron ore, which is not unfamiliar to Lao Mai, who has been working in the industrial field for many years, that is, he understands where this underground cast iron layer comes from, and it is very convenient for gold cultivators to extract gold elements from underground iron ore to form a cast iron layer.

Piercing through such a small hole an inch wide, if it were just Lao Mai himself, he could have shrunk through it, but Yu Mu and the other clothes were not small, and it was obvious that everyone couldn't get through it together.

Lao Mai sighed, where else did he have to do this hard work, and after hearing that there was no movement outside, he cast a trick and divided the brick magic tool into one hundred and eight small drill bits, and arranged them into a circle with a diameter of one meter, a total of thirty-six groups.

Lao Mai's Endless Destruction and Ten Thousand Beasts are all trained to reach the first level, and he can use three combos and thirty-six groups of attacks.

This is much more difficult than a game of picking up stones, he has to carry the teleportaries, first neatly distribute the little drills into the air, around the small iron hole he just chiseled through in a circle, and then quickly pinch a few tricks, wave his hand to let the little drills drill into the ground.

Only listening to a series of drilling sounds, after exhausting his strength, Lao Mai saw that it was less than half a meter drilled, and he understood in his heart that it was scattered into dozens of parts, and its strength was naturally not as good as the three above.

However, the depth of half a meter also indicates that this time the expansion of the hole will take more than double the effort at most, which is not a difficult task.

Lao Mai waved his hand several times, and finally drilled into the laterite layer again, so he breathed a sigh of relief, thought about it, merged the little drill bits, turned them into a large stone cake, pressed it on the circle with thirty-six holes around it, and sat cross-legged to breathe.

Punching holes with all his might one after another, Lao Mai also has to spend a lot of effort, and his body is inevitably tired, and he needs to adjust his breath to recover, and he will have work to do for a while.

It seemed that the people outside also heard some movement inside, and the sound of persuasion sounded again, but Lao Mai took care of his pranayama and recovered, turned a deaf ear, and ignored their noise, anyway, no one dared to come in.

Maybe I couldn't hear the movement again, but at the same time I felt that the person was still inside, and I shouted a few times outside, but I didn't see any reaction, so I stopped and sat up outside.

The current situation is that no one inside and outside can help anyone, and the people outside want to catch them alive, and use them to extract their souls and refine their souls to get their benefits, since they can't attack and arrest people, they have to squat outside to discuss methods.

In their opinion, although Lao Mai's skill inside is high, he is trapped and can't get out or escape, and it is normal for him to make some movement for a while.

After Lao Mai finished pranayama, he felt that his body was full of strength, so he took off the wave shoes he was wearing, which were foreign objects and could not withstand strong squeezing, but he stood barefoot on the big stone cake, and carried ten percent of his true yuan power, and fell down, and the huge gravity shook the cast iron layer humming.

The buzzing sound of the cast iron layer was also heard by the people outside, and after listening for a while, they felt that Lao Mai's efforts were in vain and in vain, where was the several meters thick cast iron layer and the ancient prohibition so easy to break, they simply stopped making a sound of persuasion, and meditated quietly and ignored it.

Lao Mai fell a few times in a row, and found that the one-meter-diameter cylindrical cast iron ring was pressed down by the stone cake and began to break, and he happily thought to himself that this was a good thing, and he had to continue to practice.

After a few more falls, the cylindrical cast iron pillar has completely broken away from the cast iron layer and began to penetrate into the iron-rich laterite layer.

Lao Mai was overjoyed, grinned silently and laughed a few times, immediately sat down on the big stone cake, collected all the things wrapped in the Gangqi Imperial Body, and transported ten successes, only to listen to the sound of the brush, the iron cylinder that broke away from the cast iron layer was inserted into the laterite layer at once, and even the rock layer below was pierced through.

I don't know how many meters deep, completely trapped in the laterite iron ore rock layer, Lao Mai paid attention to maintaining the Gang Qi Imperial Body, while leaving the cylindrical cast iron body and retreating to the depths of the ground.

Although there are definitely no characters in the Jindan period outside, they are all those who build the foundation of the Great Perfection, and I don't know how many people there are, once they desperately come forward to fight, it doesn't matter if they want to break through or fight, I'm afraid that if they don't pay attention to hurting Yu Mu, it's not appropriate just to shake.

Therefore, Lao Mai thought hatefully: "Why don't you wait for this group of old cows first, write down this one, and then wait for Lao Tzu to find out who is involved, and find out one by one to settle the general account." ”

It is not too late for a gentleman to take revenge, ten years is not too late, and of course he himself is now as far away as he is.

After walking a hundred and ten kilometers underground, Lao Mai breathed a sigh of relief and stretched out his hand to remove Yu Mu's closed five senses.

Yu Mu's five senses can be used immediately, but at a glance, the surroundings are still pitch black, he can't see or touch his eyes, he is very frightened in his heart, and asks in a low voice: "Brother Mai, where are we now, why is it so dark?"

Lao Mai made up an excuse and said: "Sister Miki, we are now in the cave, and there is no light, of course, it is dark." ”

"Drill into the cave, then you can't see it, why are you still walking so fast?" Yu Mu was not stupid, and obviously felt Lao Mai moving quickly in the dirt.

Lao Mai said with a smile: "Brother Mai, I have a pair of cat's eyes, of course I can see the road and run fast." ”

Yu Mu had long been accustomed to his child-like talking, rolling her eyelids and pointing her mouth in disbelief, and she had long been familiar with Lao Mai's occasional magical tricks.

However, she was continuously closed to her five senses, which made her very mentally tired, and after eating a few biscuits and chocolates, she said I want to sleep, and fell asleep around Lao Mai's neck.

Lao Mai saw that she was already asleep, so he breathed a sigh of relief, and concentrated on exerting his earth to retreat forward.

Having said that, from the moment Lao Mai fled, the people guarding outside the wooden tower suddenly found that there was no movement in the tower since then.

Together with the thin middle-aged man who was the bait, there were a total of seven Foundation Building Stage cultivators, and six of them were the pinnacle of the Foundation Building Great Perfection.

At this time, a cold old man in metallic clothes suddenly spoke: "There is a gold element in the hair, and it is out of the cast iron layer and goes straight down, I don't know why, Namai is only a pure earth person, and it is impossible to control metal." ”

An old man in a white-bearded gray sermon robe asked, "How far down?"

The golden old man felt it and replied: "It's not far, and there is no movement for ten meters down." ”

A yellow-robed old Dao suddenly exclaimed, "Poor Dao feels that there is no breath of Mai in the tower anymore. ”

This old Dao is the Immortal Dao Sect Elder Ping Xuzi of the pure earth attribute, and he is most familiar with the aura of the earth cultivator.

When everyone heard this, they were immediately shocked, and when the old man in the regular clothes of the fire attribute pinched a few tricks, only to hear the fire in the tower, and the sound of the blow, it seemed to burn all over the bottom of the tower.

The gray cloth old Dao muttered: "Poor Dao feels that Mai has gone away, and there is no existence in the wooden tower that traps the pure earth attribute people. ”

This old Dao is a peak cultivator of the Great Perfection of Foundation Building with a partial wood attribute, and he feels that things are more sensitive than others through the wooden tower.

Ping Xuzi gritted his teeth and said, "Fellow Daoists, let's join forces to open the formation prohibition and see what happens." ”

The old man nodded and said: "I agree, I wait for the six Great Perfection Peak Inheritors, although he can't help a pure attribute awakening inheritor, he is only a half-step golden pill at the peak of the Great Perfection, and he can't hurt us either." ”

The rest of the people who had never spoken and were all water attributes also nodded in agreement, and one of them was the elder Shui Xuanzi of the Immortal Sect.

So, except for the thin man in the early stage of foundation building, the three customs present set up a formation, and each pinched the trick to open the formation prohibition, only to see the five-colored auspicious light flashing, and a layer of mist shrouded in the entire tower dissipated, and the original prohibition was quietly opened.

I saw Ping Xuzi take the lead, stepped forward and pushed open the wooden door, and stared at the center of the hall, between a pile of sawdust, the round hole of a meter square and a black hole.

The other six people gathered around at once, and everyone couldn't help but open their mouths wide.

Especially the Pingxuzi who is at the peak of the Pure Earth Attribute Great Perfection realm, what kind of cultivation realm Lao Mai was at the beginning, he is very clear about the fighting, and he is tied with himself, even if his skill is high, it is not high.
